Summary of Field Work: |
The primary purpose of this ship request (2007-2009) is to participate as a project within the BEST field sampling team composed of a collaborative network of proposals. Our planned benthic sampling effort takes one hour of wire-time at the shallow Bering Sea depths to be studied during BEST. Our generic ship deployment requirements are for a 1/4 inch wire diameter winch for deployment of our 0.1m2 van Veen grabs (50 kg) and single HAPS core (70 kg) (either mid-ship or stern deployment), although a 9/16th inch stern wire is needed for use of our multi-HAPS corer (275 kg). As part of our BEST proposal, we request: 1) three additional ship days on the Healy just before our NSF-funded Healy cruise in May 2007 (Lovvorn et al.) in the northern Bering Sea in order to sample 16 additional stations in the middle Bering Sea transition zone where the current groundfish-dominated ecosystem transitions to a benthic-dominated ecosystem between St. Matthew and St. Lawrence Islands; and
2) benthic measurements at process stations within the core 30 day BEST icebreaker cruise to sample in a grid from south to north in the Bering Sea during the early season as outlined in the BEST implementation plan. We will participate in one BEST process cruise each year in 2007-2009 during the ice retreat in the spring period. |
