9632596 DAVIS A major goal of the U.S. GLOBEC Northwest Atlantic Field Studies Phase 2, Georges Bank Program is to examine the immigration and emigration (source, retention, and loss) of target species from the Bank. Toward this end, a field study is proposed in which focused high-resolution sampling will be conducted with the Video Plankton Recorder (VPR) to quantify average and episodic transport processes that move the copepods Calanus and Pseudocalanus across the boundaries of the Bank during the spring development of these populations. The major circulation processes to be studied include: 1) the inflow or source of copepods along the northern edge of the bank; 2) the degree of closure of the gyre and retention of copepods, and 3) the losses of copepods, due to mean along-shelf flow to the west as well as detrainment of bank copepods to the south by eddies and warm-core rings. This project will be carried out collaboratively with the Brink et al. SeaSoar/(VPR) study (9632349). ***

9632596 DAVIS美国GLOBEC西北大西洋实地研究第2阶段的一个主要目标，乔治银行计划是检查目标物种的迁入和迁出（来源，保留和损失）。为此，提出了一项实地研究，其中重点高分辨率采样将进行视频浮游生物记录仪（VPR），以量化平均和情节运输过程中移动的桡足类哲水蚤和Pseudocalanus跨越银行的边界在春季发展这些人口。 要研究的主要环流过程包括：1）沿着海岸北方边缘桡足类的流入或来源; 2）环流的闭合程度和桡足类的滞留; 3）桡足类的损失，这是由于向西的平均陆架沿岸流以及涡旋和暖心环将海岸桡足类驱离到南部。本项目将与Brink等人的SeaSoar/（VPR）研究（9632349）合作开展。 ***
