PILOT YEAR (1998) WORKGROUP

The following list is a TENTATIVE cruise schedule for the pilot year field program. Details may change to better meet program and scientific objectives. This schedule was put together by PIs from the proposals of Fahnenstiel et al., Vanderploeg et al., Cotner et al., and Gardner et al. proposals, but has also received input from PI's from the sediment resuspension and transport groups. The current plan is to have three main cruises, with 2 additional cruises in late fall to establish the extended annual monitoring efforts. The first cruise would be aboard the Lake Guardian in the fixed time slot of the Feb 1 - Feb 14. The second cruise would be aboard the RV/Laurentian and is scheduled to occur after a turbidity plume has developed. Linda Sicko-Goad indicated that the ship will be available and on call from early February through mid-April and will block out this period of time for us. We have requested 21 science days, with additional days for transport and loading to be calculated if necessary. We anticipate a 5-10 day interval or warning before a major resuspension event occurs to allow for the specific scheduling of the cruise. The "event" cruise will be staged in 3 legs according to our defined sampling activities of:

1. Survey Cruises,
2. Process Studies, and
3. Lagrangian Studies.

The ship will return to port for exchange of equipment and personnel in between each stage. A third cruise aboard the RV/Laurentian will occur in the fall and will focus on sediment collection for identifying meroplankton and surveys of plankton distributions. See figure for station locations and transects. Tentative cruise outlines are presented below.

Cruise Termination: Muskegon

Tentative Dates: Mar 1 - Apr 15, 1998 - Immediately following leg 2 Ship: RV/Laurentian Leg 3 of 3: Lagrangian Studies No. Working Days Needed (24h/day): 7 days Chief Scientist: Gary Fahnenstiel, NOAA/GLERL Scientific Personnel: Fahnenstiel (3), Vanderploeg, Cotner (2), Gardner, McCormick Cruise Origin: Muskegon Cruise Track and Time Intervals: Study Site A: Release drifters Follow 1 drifter or Centroid and do process studies on Day 1, Day 4, Day 7 and do hydrographic profiling each day. Possible add a geo-stationary stations for comparison to lagrangian site Cruise Termination: Muskegon

Tentative Dates: October 1998 Ship: RV/Laurentian No. Working Days Needed (24h/day): 6 days Chief Scientist: Linda Sicko-Goad, CGLAS/Univ. Michigan Scientific Personnel: Goad (2), Vanderploeg (2) Cruise Origin: Muskegon Cruise Track and Time Intervals: Monitoring at GLERL's 45m and 110m stations - 1 day Monitoring at primary station site A - 1 day Sediment collections throughout MIAA study region - 4 days Cruise Termination: Muskegon

Tentative Dates: November 1998 Ship: RV/Laurentian No. Working Days Needed (24h/day): 2 days Chief Scientist: Vanderploeg, NOAA/GLERL Scientific Personnel: Vanderploeg (2) Cruise Origin: Muskegon Cruise Track and Time Intervals: Monitoring at GLERL's 45m and 110m stations - 1 day Monitoring at primary station site A - 1 day Cruise Termination: Muskegon

Tentative Dates: December 1998 Ship: RV/Laurentian No. Working Days Needed (24h/day): 2 days Chief Scientist: Vanderploeg, NOAA/GLERL Scientific Personnel: Vanderploeg (2) Cruise Origin: Muskegon Cruise Track and Time Intervals: Monitoring at GLERL's 45m and 110m stations - 1 day Monitoring at primary station site A - 1 day Cruise Termination: Muskegon

NOTES: The sediment resuspension and transport group requests help to pump large samples of water (500 liters) through cartridge filters at each of our sampling stations, during each of the "event" cruise legs. The pumping system is independent of the winch and would take approximately 0.5 hrs per site.
