December 30, 2002Contents 1. Great Lakes Oceanography A field intensive 1-week course (May 4-11)will be taught at NOAA/GLERL's
Lake Michigan Field Station in Muskegon,MI. Students will participate
in a week long cruise aboard the R/V Laurentian using the latest
physical and biological oceanographic methods (e.g.,moored instrument
arrays,state-o -the-art profiling systems,etc.).The course will
focus on physical measurements,and Despite the limited class size (12 students) we would like your help in advertising the availability of this course broadly. I have a pdf flyer posted off my main web page (www.glerl.noaa.gov/seagrant) 2. New Reprint - Ice ASSEL, R.A. and D.C. NORTON. Twentieth Century trends in the ice cover of the Laurentian Great Lakes of North America.

Science.gov makes research more accessible to the public A new federal Web site aims to make scientific information gathered
by different agencies more accessible to the public. The site,
www.science.gov, is an offshoot of Firstgov.gov, and is especially
useful because it houses information under one roof from the multiple
agencies that perform scientific research, said Eleanor Frierson,
deputy director of the National Agricultural Library and co-chair
of the science.gov Alliance, the interagency group that created
the site.
"Science.gov provides the unique ability to search across
the content within databases as well as across Web sites," Frierson
said. "It shows that federal agencies can work together to
pull off The site, which is geared toward a wide audience that ranges from
academics to private business owners, offers a compilation of information
from 10 government agencies and 14 scientific and technical organizations.
The Agriculture, Commerce {including NOAA}, Defense, Education,
Energy, Health and Human Services and Interior departments, as
well as the Environmental Users can search for technical reports, journal citations, databases, fact sheets and links to other federal Web sites by clicking on one of 12 subject areas such as "agriculture and food" or "health and medicine." Or they can complete a general search across all subject areas. Access to the site is free and does not require registration. "Science.gov aims to bring the substantial resources of the federal science and technology enterprise together in one place," said John Marburger, director of the White House Office of Science and Technology Policy, in a statement. "The site is a great example of e-government in action." |

Lab team member When I first came to GLERL, Tom Nalepa was looking for a person
who could take care of his field-work program, which included becoming
a NOAA SCUBA diver and performing laboratory analyses. After 11
field seasons supporting Tom Nalepa, research is still my primary
duty. This year my research included approximately 30 days of travel
to Muskegon, Milwaukee, Cheboygan, This past year my secondary duty was as a SCUBA diver and field
support person for the newly established NOS Thunder Bay National
Marine Sanctuary (TBNMS). As the only formally trained NOAA certified
diver available in the region, I was designated Unit Diving Supervisor
and given responsibility for all aspects of SCUBA operations at
TBNMS. This included the training and 5. New Faces at GLERL Dennis Schornack, newly appointed chair of the U.S. section of the International Joint Commission, and his assistant John Nevin now have an office at GLERL Stephen Schneider, Managing Editor of the Journal of Great Lakes Research for IAGLR has taken up residence in GLERL. Dr. Stuart Ludsin joined GLERL as a federal research scientist, working with Dr. Brandt on a NOAA-COP project on Ecosystem Forecasting in Chesapeake Bay. His research explores mechanisms that regulate fish population and community dynamics and seeks to apply ecological understanding to management/conservation problems in aquatic systems. Nate Bosch, an incoming PhD candidate at the University of Michigan is currently completing a research fellowship with Dr. Tom Johengen doing nutrient analyses on the NOBOB ballast-residual study. Jessica Bleha (B.S. University of Michigan) will be helping to process trap samples from Lake Michigan through the end of February (when she leaves for graduate work in Australia). Erin Cooney, an undergraduate at the University of Michigan is working with Hank Vanderploeg to convert tabulated files on phytoplankton species composition of Saginaw Bay into electronic format for later statistical and modelling studies (funded by U of M work/study). |

November 26, 2002NOAA GREAT LAKES SEMINAR SERIES Wednesday, December 4 - 2:00 p.m. Monday, December 9 - 2:00 p.m. Abstract: One of the most important mechanisms for the introduction of aquatic nuisance species is transport in ship ballast waters. Although several ballast tank treatments to prevent transport of aquatic organisms appear promising, all existing approaches will result in significant costs to the shipping industry. This seminar will describe a treatment that can dramatically reduce the survivorship of most organisms found in ballast waters while providing economic benefits to ship owners. Purging of oxygen from ballast tanks with nitrogen was recently found to be a cost-effective technique for reducing corrosion and therefore extending ship life. We tested the tolerance of larvae of known invasive invertebrate species to low levels of oxygen, comparable to those resulting from this anticorrosion treatment, and detected significant levels of mortality. Two separate literature reviews further support the conclusion that few organisms will be able to withstand extended periods of exposure to nitrogen treated ballast water. This novel deoxygenation technique may therefore have direct benefits to both marine conservation and the shipping industry. Currently investigation are being initiated to optimize the oxygen stripping process, to examine Microbially Influenced Corrosion under hypoxia, and to examine deoxygenations's effectiveness at removing ballast water organisms onboard active vessels. |

November 18, 2002Contents: 1. NOAA Great Lakes Seminar Series at GLERL All GLERL seminars can be recorded for viewing by Sea Grant staff on request. Thursday, November 21st @ 10:30 AM The Lake Erie Center was established in 1998 as a multidisciplinary center dedicated to exploring the linkages between land use and water quality in the western catchment of Lake Erie. In 2002, a two-part program was established to help fulfill this mission: I. To monitor the water quality of Maumee Bay and the southwest portion of the Western Basin. II. To establish an interactive database of historic and current data on the Maumee River catchment, Maumee Bay, and western Lake Erie. This seminar will provide an introduction to the Lake Erie Center, including research facilities available to collaborating scientists. We will also present the preliminary results of monitoring efforts in 2002 with conclusions that may have relevance for the "dead zone" phenomenon in Lake Erie. Finally, we will present a prototype of the environmental database. 2. New Reprints - Circulation & Photosynthesis McCORMICK, M.J., G.S. MILLER, C.R. Murthy, Y.R. Rao, and J.H. SAYLOR.

October 31, 2002Contents: This week, Earthwatch Radio is featuring a story - "Memories of Great Lakes"with comments by GLERL meteorologist Brent Lofgren. Story is listed at: http://www.seagrant.wisc.edu/earthwatch/program.asp?ProgramID=3322 2. MIL - Automated observing systems GLERL's Marine Instrumentation Laboratory (MIL) is developing the first Great Lakes observatory ustilizing wireless/internet technology at the Lake Michigan Field Station in Muskegon. When fully developed, the observatory will provide chemical, physical and biological data to support long-term research. The goal of this project is to put in place the infrastructure needed to simplify sensor deployment and data acquisition with the goal of providing information that is accessible to scientific researchers, educators and the public. This data will be available to the scientific and educational community via the internet through real-time broadcasts. Over the summer, GLERL staff deployed and tested two vertical profilers with instrumented tripods and a fixed direction communication mooring for over 30 days. More information can be found at: www.glerl.noaa.gov/mil/profiler.html and http://pcrealtime.glerl.noaa.gov/tripods/ 3. Copepod Research Presentations Hank Vanderploeg gave an invited presentation of results at the 8th International Conference on Copepoda in Keelung Taiwan titled "The effects of oligotrophication, interannual variability in weather, and nonindigenous fishes and intevertebrates on the copepod community of Lake Michigan." Gretchen Messnick of NOS Cooperative Oxford Laboratory, who has been working with Hank on the 'zooplankton tumor problem' presented a paper 'Histological Characteristics of Abnormal Protrusions in Copepods from Michigan Lakes'. This paper has also been submitted to the journal, Zoological Studies. 4. Ship News Th addition of the RV/Laurentian to the NOAA 'fleet' on the Great Lakes has greatly increased the amount of shipboard time available for research this summer. Several improvements have been made to the Laurentian including addition of a second conductive cable winch, a reconfigured wet lab, and an electronic charting display so that crew can view ship speed, track lines and ETA to the next station from the lab. Renovation of the Shenehon was also completed, just months prior to her 50th anniversary. Small boat usage is also up with the addition of an A-frame and winch to the Cyclops which increases versatility and capability for larger trawls, net tows and towed electronic instruments. The mix of shipboard projects has also been more diverse than in recent years, with more work in the areas of fisheries, ROVs, towed cameras, side scan sonar, bottom coring and dive operations. Much of the work in Alpena (aboard the Shenehon) is in support of archaeological efforts at the National Marine Sanctuary and the Laurentian was employed to explore an unknown wreck (originally thought to be the Chicora) in Lake Michigan. The Shenehon is now out of the water for the season. 5. New faces Dr. Mary Cardenas joins GLERL as a visiting scientist. Dr. Cardenas is on sabbatical from the Engineering Department at Harvey Mudd College in Claremont, CA. She will be working with Dave Schwab and Dmitry Beletsky on computer modeling of sediment dynamics in Lake Michigan. Dr. Cheegwan Lee joins GLERL as a National Research Council Fellow. Dr. Lee recently graduated from the University of Wisconsin and will be working with Dave Schwab, Nathan Hawley and Brian Eadie on sediment dynamics.

October 18, 2002Contents: A $0.5M proposal developed by David Reid in collaboration with the Naval Surface Warfare Center, Carderock Division (West Bethesda, MD) was successful against a field of over 40 competing proposals received by NOAA Headquarters in response to a national RFP for ballast water treatment projects. The new project, titled "Computational Modeling of Ballast Tanks to Improve Understanding and Maximize Effectiveness of Management Practices and Treatment Mechanisms" involves computer-based computational fluid dynamics modeling and scale model experimental validation to study the flow dynamics and predict the efficacy of the flow-through exchange method as a ballast water management and treatment practice. Ballast water discharge is considered to be the number one mechanism responsible for the exponentially increasing successful invasions of aquatic species into coastal ecosystems. There are more than 45,000 commercial cargo vessels operating on the world's oceans. Mid-ocean ballast water exchange (BWE) is presently the primary management practice with widespread acceptance for reducing or preventing the spread of nonindigenous aquatic species via ballast water. Although efforts are underway to replace ballast exchange with technology-based treatment systems, ballast exchange will likely continue for the foreseeable future and may ultimately be combined with some other technologies and management approaches. Therefore, it is essential to fully understand the ballast exchange process and what occurs inside a ballast tank during exchange. Attempts to experimentally determine the effectiveness of BWE have produced inconsistent and generally unsatisfying results. Conducting on-board experiments during exchange is complex, labor intensive, time consuming, and only allows one shot at successfully detecting the relevant conditions inside the tank. Logistics of sampling the conditions inside a large compartmentalized ballast tank make it very difficult to resolve internal fluid dynamics and flow structures in these tanks. Additional experiments are usually delayed until the ship has another ocean crossing, which could be weeks later. Ship schedules are subject to change and often on short notice, thus disrupting planned experiments. These difficulties have limited the experimental design and resolution of sampling needed to determine exchange effectiveness. The GLERL-Carderock proposal suggested that an approach utilizing computer-based modeling of the flow dynamics in ballast tanks makes sense and could provide several advantages over the experimental approaches to date, as well as enhancing understanding of experimental results. The ballast water exchange proposal will build on the experience gained by the Navy modelers over the last six years. We anticipate that the results of the proposed work may help explain the variable results of ballast water exchange experiments documented to date, improve the design of such experiments, lead to ballast tank modification recommendations to improve overall ballast water exchange effectiveness, minimize deadspots, and reduce sediment deposition and accumulation, thus reducing the threat of coastal invasive species being discharged in our coastal ecosystems. The new project will start in early FY2003. 2. Six Month Publications Update April 2002 - September 2002 ASSEL, R. A., D. C. NORTON, and K. C. CRONK. A Great Lakes ice

Brandt receives Presidential Rank Award 11 of NOAA's very best leaders have been selected to receive 2002 Presidential Rank Awards - including GLERL director Dr. Stephen Brandt. Presidential Rank Awards are the most prestigious recognition bestowed on career Senior Executives. Selectees are officially recognized as "strong leaders who achieve results and consistently demonstrate strength, integrity, industry and a relentless commitment to excellence in public service" - all hallmarks of NOAA's core values. Each recipient was selected following a rigorous selection process. After being nominated by NOAA and endorsed by the Department, each was evaluated by a board of private citizens, receiving final approval from the President himself. They will be recognized personally in separate ceremonies by both Secretary Evans and President Bush. DR. STEPHEN B. BRANDT, director of the OAR Great Lakes Environmental Research Laboratory in Ann Arbor, is cited for excellent organizational leadership. Since arriving at NOAA's only multidisciplinary laboratory focusing on Great Lakes and coastal issues, Steve has engaged staff at all levels in decision-making and problem-solving; fostered recruitment, retention and training of next-generation scientists; and generated strong partnerships with universities, state and federal agencies that have resulted in new science programs for NOAA, joint academic-federal appointments, plans for a multi-institutional facility, and acquisition of a research vessel. His initiatives created new multidisciplinary programs critical to science-based decision-making. Other NOAA recipients include Dr. Thomas R. Karl, Dr. James Balsiger, Dr. Eddie N. Bernard, Gary K. Davis, Dr. David J. Hofmann, Dr. James E. Hoke, Dr. Edward R. Johnson, John Kelly, Louisa Koch and Gregory W. Withee. 5. Reid and Eadie receive NOAA Bronze Medal Awards It gives me great pleasure to announce that Dr. David Reid and Dr. Brian Eadie have each won the NOAA Bronze Medal Award. The Bronze Medal Award is the highest honorary award given by the head of NOAA and is defined as superior performance characterized by outstanding or significant contributions which have increased the efficiency and effectiveness of NOAA. To warrant a Bronze Medal, a contribution must focus on qualitative and quantitative performance measures cited in the Department's Strategic Plan and be identified in one of the following areas: leadership, personal and professional excellence, scientific/engineering achievement, employee development, customer service, administrative/technical support, or public service or heroism. Brian Eadie is recognized for his Scientific Leadership in NOAA and, in particular, for his leadership in the EEGLE program and his innovation and leadership as a Science Branch Chief during the last two years. David Reid is recognized for his Scientific Leadership in NOAA and, in particular, for his leadership in developing GLERL as the leader in NOBOB/Ballast research on Invasive Species within NOAA. There will be a ceremony in Washington on October 22, recognizing Brian and Dave and the other NOAA Bronze Medal winners. 6.

September 24, 2002Contents Title: Effects of omnivory in marine planktonic food webs Abstract: Omnivory in marine calanoid copepods was manipulated by the presence/absence of microzooplankton in model food webs. The presence of microzooplankton caused changes in abundances of various phytoplankton groups, and enhanced reproduction in calanoid copepods. Further experiments on calanoid copepods with diatoms and heterotrophic dinoflagellates as prey revealed that positive effects of microzooplankton on copepod reproduction cannot be attributed to differences in the copepod's feeding efficiency. Rather, microzooplankton caused 'trophic upgrading' of the phytoplankton prey for calanoid copepods. Recent findings about negative effects of pure diatom diets on reproduction in calanoid copepods may be relativized by these results, since diatom blooms are usually accompanied by high abundances of heterotrophic dinoflagellates.

Muskegon Field Station Facilities Upgrade Approved Thanks to Dennis Donahue's outstanding facilities management and proposal writing skills, the Lake Michigan Field Station will receive $270,000 for needed improvements from the NOAA's Facilities Maintenance Project Prospectus program. Although this will not cover the entire amount of improvements, it will make a significant impact on revitalizing LMFS. Improvements were requested under three categories: 3. 2003 NOSB GLERL will again be co-sponsoring the NOSB Midwest Regional Competition. The 6th Annual Competition which will be held on Saturday, February 8, 2003. In this upcoming competition, we will include team challenge questions

David Reid at the Great Lakes Environmental Research Laboratory
in Ann Arbor, Mich., and Hugh McIsaac at the University of Windsor.
The group tested ships last year -- usually ones that made their The resting eggs hatched readily in lab conditions, so this year they'll look for any evidence of hatching on board, work that's done with the help of companies such as Montreal-based Fednav, which says it let scientists test empty ballast tanks on a ship last season. Reid says the work is difficult, especially because the researchers can't interfere with the ships' operation. He also says it's tough to adequately sample a ballast tank, which he describes as a honeycomb of cells. Reid says samples taken directly under access hatches may not represent what's really happening throughout the tanks, where water may not mix thoroughly and where it may stay trapped. 4.

The team won the all expense paid trip to LMFS 4. GLERL in the News - Water Levels ... although Lake Michigan's water levels are up from last year, they still are below normal, said Cynthia Sellinger, a hydrologist at the National Oceanic and Atmospheric Administration's Great Lakes Environmental Research Laboratory in Ann Arbor, Mich. "Since 1997, Lake Michigan's levels have been dropping off," Sellinger said. "But we're up 10 inches from last year - putting us back to the 2000 levels." The reasons for this drop - and recent increase - are pretty well understood. But what is less apparent is whether this year's increase is a sign of things to come - or an aberration in a larger decline of water levels. Since 1997, Lake Michigan's surface has dropped 3.4 feet. "It's been a pretty steady decline," said Sellinger, who, like other researchers studying the fluctuations of water levels in Lake Michigan, thinks the trend of decreasing levels is related to the weather. "It's a combination of low precipitation and higher-than-average temperatures," she said. "And because we've had warmer winter temperatures than usual for the past five years," and therefore, no ice, she said, the amount of water lost to the air has been enormous. Last winter, however, the situation was ameliorated by "a combination of near-record snowfall and a bigger supply of water into the lake" through streams and rivers, said Keith Kompoltowicz, physical scientist and meteorologist with the U.S. Army Corps of Engineers in Detroit. But whether this latest resurgence of water into the lake is the beginning of a new trend "is anybody's guess," Kompoltowicz said. The article also highlights research by Todd Thompson, associate scientist at the Indiana Geological Survey, on at ancient climatological records and by Brent Lofgren, a physical scientist at GLERL, on climate change predictions. |

July 18, 2002A short one this week... Contents: ABSTRACT: Herein, we document changes in the Lake Michigan food web between 1970 and 2000 and identify the factors responsible for these changes. Control of sea lamprey (Petromyzon marinus) and alewife (Alosa pseudoharengus) populations in Lake Michigan, beginning in the 1950s and 1960s, had profound effects on the food web. Recoveries of lake whitefish (Coregonus clupeaformis) and burbot (Lota lota) populations, as well as the buildup of salmonine populations, were attributable, at least in part, to sea lamprey control. Based on our analyses, predation by salmonines was primarily responsible for the reduction in alewife abundance during the 1970s and early 1980s. In turn, the decrease in alewife abundance likely contributed to recoveries of deepwater sculpin (Myoxocephalus thompsoni), yellow perch (Perca flavescens), and burbot populations during the 1970s and 1980s. Decrease in the abundance of all three dominant benthic macroinvertebrate groups, including Diporeia, oligochaetes, and sphaeriids, during the 1980s in nearshore waters (less than or equal to50 m deep) of Lake Michigan, was attributable to a decrease in primary production linked to a decline in phosphorus loadings. Continued decrease in Diporeia abundance during the 1990s was associated with the zebra mussel (Dreissena polymorpha) invasion, but specific mechanisms for zebra mussels affecting Diporeia abundance remain unidentified.

July 10, 2002Contents _______________________________________________________________ "The Regional Integrated Sciences and Assessments (RISA) Program of NOAA's Office of Global Programs (OGP) represents an important innovation in how our nation conducts science related to climate variability and society. Explicit in the RISA program is real partnership between the scientific community and the users (decision-makers or "stakeholders") of scientific knowledge. Close stakeholder involvement is new to the climate research enterprise, but the RISA's clearly demonstrate the value of this involvement. All RISA effort is focused on climate research and communication of information required by stakeholders to support their decision-making, as well as to reduce their vulnerabilities to climate variability. The RISA's focus on regional- and local-scale science and information, and thus form the critical link between national science programs and the inherently regional ("place-based" or local) users of scientific knowledge." Excerpt from http://www.ogp.noaa.gov/mpe/csi/risa/teams.html GLERL's Brian Eadie is spearheading an effort to get a Great Lakes RISA designated in the next round (RFP expected in 2003). The existing 5 RISA's are located in the Interior West, the Northwest, Southwest, California and Florida. We are likely to see considerable competition from the Northeast in the next round. As a precursor to building the partnership needed to develop a proposal, he has asked me to develop a one page description of the potential clientele, issues, and product needs of the coastal community with regard to climate change and its impacts. So, I need your help in identifying such. If you have ideas that I could/should incorporate into a one-page description of specific clientele (no more 'general public'), specific issues related to climate change which are important to those clientele, specific products related to climate change generally or to specific climate research needed by these client groups and/or specific climate-related research priorities please send them my way asap (by 7/24/02 if possible). A few thoughts from the researchers to give you an idea of the types of research and products a Great Lakes RISA might encompass: Can climate change impacts be seen in fish species (recruitment)? What is the role of upwellings on fish productivity and how will climate changes impact upwelling? What impacts will climate change have on thermal structure of the lake? Will alterations to the Great Lakes lower food web be sufficient to support the predictions of increased fish production? Improved ice cover forecasting, Probabilistic ice cover forecasting, modelling changes to lake effect snow under global climate change scenarios, modelling changes to lake circulation under climate change scenarios, addition of land use parameters to hydrology models (which can already interface to some extent with global climate change models). enhancing the interface between the current Great Lakes hydrology models and the mesoscale climate change models. For more information about what other RISA's are doing browse: http://www.ogp.noaa.gov/mpe/csi/risa/index.htm 2. GLERL Hot Items: Congressman Ehlers Keynotes at R/V Laurentian Ceremony Keynote remarks by U.S. Representative Vern Ehlers from Michigan's 3rd District highlighted a July 2nd ceremony honoring a new partnership between GLERL and the University of Michigan. Through a 15-year lease agreement, GLERL will operate and maintain the University's science vessel, the R/V Laurentian. The ceremony was held dockside at GLERL's Lake Michigan Field Station in Muskegon, Michigan where the Laurentian is now based. Following remarks by Representative Ehlers, GLERL Director Steve Brandt and University of Michigan Associate Vice President for Research, James Penner-Hahn spoke about development of the partnership and mutual benefits in advancing Great Lakes research activities of the two institutions. The ceremony ended with a ribbon-cutting ceremony in recognition of the operational transition and invited guests joined GLERL and university officials for a vessel briefing and cruise demonstrating instrumentation and sampling capabilities. Representative Ehlers is co-chair of the Great Lakes Task Force for the 107th Congress and has a long history of Great Lakes leadership on Capitol Hill. He also chairs the House Science Subcommittee on Environment, Technology and Standards with oversight of NOAA activities related to weather, weather services, climate, the atmosphere, marine fisheries and oceanic research. See also 3. GLERL Hot Items: GLERL Scientist Presented 2002 Editor's Award GLERL scientist Tom Nalepa was recently presented with the 2002 Editor's Award by the International Association for Great Lakes Research (IAGLR). The award was made on the basis of Nalepa's outstanding contributions to the review process of the Journal of Great Lakes Research. Journal Editor Gerald Matisoff noted that he had found Nalepa's solicitation and handling of manuscript reviews to be "fair, of the highest caliber and meticulous". Nalepa has served as an Associate Editor in the area of aquatic zoology since 1991 with responsibilities for coordinating peer review of submitted manuscripts and making recommendations on their publication. The International Association for Great Lakes Research (IAGLR) is a scientific organization made up of researchers studying the Laurentian Great Lakes and other large lakes of the world, as well as those with an interest in such research. Specifically, the Association promotes all aspects of large lakes research and communicates research findings through publications and meetings. Contact information: Thomas F Nalepa 4.

If I get nothing from a particular program, I will tap the communicators for articles, but information direct from the extension agents is welcome. 2. GLERL Hot Items: New Digital Great Lakes Ice Cover Data Set GLERL recently completed digitizing historical Great Lakes ice
charts from 1973 to 2000 in cooperation with the OAA/USN/USCG National
Ice Center (NIC) and the Canadian Ice Service (CIS). At GLERL the
ice cover data sets are being used for: Worldwide distribution and amounts of ice and snow (the cryosphrere) are important indicators of climate and climate change, and lake ice is a sensitive index of regional change in the Great Lakes. Given the growing concern over global warming and its potential impacts on the Great Lakes, GLERL began updating all ice cover data starting in 1994 under the auspices of NOAA's Earth System and Data Information Management (ESDIM). Ice cover has an effect on almost every aspect of life on the Great Lakes, from hydropower generation to commercial shipping to the fishing industry. The typical extent and duration of the winter ice cover changes from year to year, and long-term changes may occur because of global warming. These data sets are available on the web at: ftp://ftp.glerl.noaa.gov/ice/charts/ The readme.txt file describes the data format, file naming conventions, and ice cover codes Subcategories by winter season contain: The data set and methods used to digitize and quality control these data are documented in two Technical Memoranda which are also available on GLERL's Web Page: ftp://ftp.glerl.noaa.gov/publications/tech_reports/glerl-121/ ftp://ftp.glerl.noaa.gov/publications/tech_reports/glerl-117/ Data set users include: Contact information: Raymond A Assel, (734) 741-2268 3. GLERL Hot Items: Shenehon Attracts Hundreds at Riverfest On Saturday June 8th GLERL's research vessel, the R/V Shenehon joined the annual Riverfest celebration in Alpena, Michigan for the first time and was toured by an estimated 500 visitors. The Shenehon made its move last month from its home base in Muskegon to Alpena to spend the summer assisting the newly designated Thunder Bay National Marine Sanctuary and Underwater Preserve while continuing research on the Great Lakes. It will be used by the Sanctuary for deploying new mooring buoys as well as for gathering data on shipwrecks. Additionally, GLERL will continue to use the vessel for gathering water and sediment samples along with other research activities. The Shenehon was originally stationed at the Lake Michigan Field Station (LMFS) in Muskegon. However, recently a new partnership between GLERL and the University of Michigan provides for GLERL operation of the University's vessel R/V Laurentian under a fifteen-year lease agreement. The Laurentian will operate from the Field Station to support GLERL research on Lake Michigan as well as the needs of select University of Michigan scientists. A July 2nd ceremony is planned at the LMFS to recognize the new operational partnership. Contact information: Dennis J Donahue, (231) 755-5173 4. Laurentian Press Release 5. GLERL in the News: Climate Change and Water Levels Earthwatch Radio is a service of the Sea Grant Institute and the Institute for Environmental Studies at the University of WI-Madison Water levels in the Great Lakes have dropped about two feet over the past five years due to dry weather. Brent Lofgren says this change is probably due to natural ups and downs in the weather, but it's also a sign of what we might see in the future with global warming. Lofgren is a climatologist at the Great Lakes Environmental Research Lab in Ann Arbor, Michigan. "I would not attribute this fairly fast change in water levels to global warming, but it is similar to something that we anticipate over a longer period of time in the future." Lofgren says the drop in water levels on the Great Lakes was caused by an increase in evaporation. It's been accelerated by stronger winds and warmer air and water temperatures. On top of that, there's been more evaporation during the winter because there has not been as much ice cover. Lofgren says the result is a picture of what might become the norm as the Earth grows warmer. 6. Dr. Al Beeton is GLERL's first Emeritus Scientist I am happy to announce that Dr. Al Beeton is now GLERL's (and
NOAA's) first Emeritus Scientist. As an Emeritus, Dr. Beeton will
work closely with the Director and GLERL scientists on program
issues. Specifically, Dr. Beeton will: (1) support specialized
scientific expertise that is of long-range importance to GLERL
and the Nation; (2) investigate science research frontiers that
have potential future importance to the Nation; (3) provide seasonal
counsel to managers, individuals scientists, and teams; (4) conduct
or engage in special projects that require specialized scientific
perspectives or knowledge and that supplement and enhance normal
GLERL As part of the Emeritus process, Dr. Stephen Brandt will serve as Dr. Beeton's project scientist and will provide broad guidance on the program scope. 7.
