Date: Thu, 12 Feb 1998 15:53:30 -0800 From: Tom Johengen Organization: U.S. DOC/NOAA/GLERL Mime-Version: 1.0 To: eegle-spl@wings.glerl.noaa.gov Subject: Cruise Plans for March/April SPL Cruise on Laurentian X-Url: http://www.glerl.noaa.gov/eegle/email_archives/email_dist.html Eeglers, I am enclosing a tentative cruise plan for all three legs of the Laurentian cruises which are to take place between Mar 9 and Apr 15. This plan was put together by a committee of representatives from the appropriate study groups and directly reflects the decisions agreed upon at the Milwaukee workshop. Please review the plan promptly and let me know ASAP of any necessary modifications. The final version of the plan (including all station locations and maps) will be submitted to the Laurentian first thing next week. I will include the plan as text below, as well as, an attached WORD document. Thanks in advance for your prompt responses--Tom EEGLE: LAURENTIAN CRUISE PLAN: March 9 - April 15, 1998 Overview The cruise will be divided into three separate legs with the generalized objectives of Survey along multiple transects, Process studies at master stations, and Lagrangian experiments at multiple sites. Each leg will start on a fixed date and be allotted 12 working days to accomplish their tasks, with 2 days for turn-around of personnel and equipment in between legs. The cruise names and allotted dates are: Leg 1: SURV-1998-068 Mar 9 - Mar 20 Leg 2: PROC-1998-081 Mar 22 - Apr 2 Leg 3: LAGR-1998-094 Apr 4 - Apr 15 Personnel (F-denotes females) Leg 1 Tom Johengen, CILER/Univ Michigan (Chief Scientist) Jim Cotner, Univ Minnesota Hank Vanderploeg, NOAA/GLERL Steve Ruberg, NOAA/GLERL (F) Marie Bundy, Phil.

Station Names and Locations Transects are defined by a line from the 10m depth contour to the 110m depth contour and are named by the respective City which approximates their location along the coastline. Discrete sampling station along transects are designated by 1 or 2 initials from the transect name plus the depth of the water column at that position. [See WEB site for study area map for these cruises. URL is http://www.glerl.noaa.gov/eegle/cruises/tmp/surv-1998-068-planned1.gif]. [Iāll eventually attach the gif file once they are completed]. Please note that not all station positions are exactly fixed at this time. A general position is defined in the cruise plan below but the exact location may change as a function of the location of the sediment plume. Stations defined at 10 and 15 m depths refer to sites known to be within the plume. Stations defined at 30 and 45m refer to sites at the outer boundary of the plume. Stations defined at 80m or 110m are considered open lake or outside the plume. Data Management All sampling activities must be entered into a Cruise Operations Log which will be maintained by the Chief Scientist. Details are provided on the WEB site and in handouts kept with the log. NOTE all times and Julian Days used in the log are based on GMT (plus 5 hours from EST). Leg 1: SURV-1998-068 Task: Survey along transects at Muskegon (M), St Joseph (J), Gary (G), Chicago (C), Mid-lake Deep Basin (DB). Plus one station off Saugatuck.
