9632349 BRINK Physical and physical/biological measurements will investigate the sources, retention and losses of zooplankton and ichthyoplankton over Georges Bank during the U.S.GLOBEC Northwest Atlantic Field Studies Phase 2 program. This project will focus on issues involving retention (in the form of recirculation around the inner part of the Bank), losses from the southern flank of the Bank into the Slope Water, and losses westward into the Middle Atlantic Bight. A year-long, 9-element moored array will be placed along the southeastern end of the Bank to measure the local kinematics and dynamics of recirculation and to observe properties of the shelf break front (which is in effect the southern boundary of the Bank). Three highly resolved (1 km or better resolution) SeaSoar surveys are proposed along the southern flank to investigate losses due to warm-core rings, wind events, and shelf break eddies. SeaSoar surveys will measure normal physical variables (currents, temperature and salinity), and will include zooplankton observations made with a Video Plankton Recorder (VPR) and the Tracor Acoustic Profiling System (TAPS). ***

9632349在美国西北大西洋现场研究阶段2计划期间，在Georges Bank上，浮游生物和小浮游生物在Georges Bank上的浮游物质和物理/生物测量结果将调查浮游动物和损失的来源，保留和损失。 该项目将重点关注涉及保留率的问题（以银行内部内部的再循环形式），银行南侧的损失进入坡度，并向西损失到中大西洋中部。 为期一年的9个元素系泊阵列将沿着银行的东南端放置，以测量循环的当地运动学和动力学，并观察货架断裂前线的特性（实际上是银行的南部边界）。 提出了三项高度分辨（1公里或更好的分辨率）沿南侧面的海上调查，以调查由于暖核环，风事件和架子折断涡流造成的损失。 海景调查将测量正常的物理变量（电流，温度和盐度），并包括用视频浮游生物记录器（VPR）和示踪声原状分析系统（TAPS）进行的浮游动物观测。 ***
