Products & Services
GLERL carries out research and provides scientific products, expertise,
and services required for effective management and protection of Great
Lakes coastal ecosystems. GLERL has a fundamental responsibility to produce
high-quality scientific information that addresses issues of importance
to the nation regarding the wise use of the Great Lakes and marine coastal
environments. The research is both proactive (to provide the basic understanding
of how aquatic ecosystems work so that issues can be identified and solved
before they become problems) and reactive (to respond to those issues
deemed highly relevant to society). Scientific output must be readily
available to those who need it.
GLERL research results are published in the form of scientific journals
and technical reports. NOAA Technical Reports are scientific and
technical papers that, because of their length or their large data
sets, are not suitable for publication in scientific journals. This
series includes NOAA Technical Reports, NOAA Technical Memorandums,
and NOAA Data Reports. Most files are in PDF format with any associated
data files, figures, and programs available from GLERL’s FTP site.
Poster presentations from scientific meetings, workshops, and conferences.
One to two page descriptions of a few of our current research
projects and results. Written in plain-language and loaded with
color and graphics, these are perfect for the non-scientist.
A collection of Great Lakes images. The gallery is organized
into nine different categories: Facilities/Vessels, Fieldwork, Fish,
Ice, Lake Levels, Logos, Maps, Scenic, and Waterlife. We will update
and add to this site as more images become available.
Technology development at GLERL encompasses both hardware
and software development. The Marine Instrumentation
Laboratory performs engineering research and development
activities in support of GLERL projects, furthers the advancement
of marine technology, and provides instrumentation maintenance and
field support for GLERL scientific projects. The other component
of technology development is project specific software development.
Numerical models are used to predict water levels, the fate and
transport of toxic substances, and fish recruitment, among others.
Computer software developed at GLERL is also used as a research
and management tool; to better understand certain processes and
how best to manage resources.
The GLERL Library supports the laboratory’s research activities and
the collection reflects an emphasis on freshwater and coastal sciences, particularly in the
Great Lakes basin. The GLERL library is open to the public for research purposes, Monday
through Friday from 8:30 am - 4:30 pm.
GLERL research vessels include the R/V Laurentian, R/V Storm, and R/V Cyclops.
These vessels are also available to select institutions conducting Great Lakes research.
Great Lakes water levels constitute one of the longest high quality hydrometeorological
data sets in North America with reference gage records beginning about 1860 with sporadic
records back to the early 1800s.
GLERL’s Marine Instrumentation Laboratory has deployed and is maintaining
a real-time network of shore-based meteorological instrument packages
in Wisconsin, Michigan, Illinois, Indiana, and Ohio. Stations in
Alpena, MI, Muskegon, MI, Chicago, IL, Milwaukee, WI, and Toledo,
OH also include web cameras. All meteorological observation stations
measure and record wind speed, wind gust, wind direction, air temperature,
and wind chill. In addition, instruments in Muskegon measure dep
point, relative humidity, atmospheric pressure, and light level.
This data as well as camera images are updated at 5-30 minute intervals
and displayed on GLERL’s web site.
