Georges Bank Northeast Peak ADCP mooring data from GB NEP Mooring NEP_buoy_dep3.1 in the Georges Bank, Northeast Peak from 1996 (GB project)

<p>\"As part of the U.S. GLOBEC Northwest Atlantic/Georges Bank program, moorings were deployed on Georges Bank as part of the broad-scale survey component to help measure the temporal variability of both physical and biological characteristics on the Bank. The array consisted of a primary mooring site on the Southern Flank which was maintained for the full 5-year duration of the field program, plus secondary moorings, with fewer sensors and of shorter duration, in the well-mixed water on the Crest and in the cod/haddock spawning region on the Northeast Peak. Temperature and conductivity (salinity) were measured at 5-m intervals, ADCP velocity profiles were obtained with 1-m vertical resolution, and bio-optical packages (measuring fluorescence, optical transmission and photosynthetically active radiation) were deployed at 10-m and 40-m depths. Bottom pressure was measured at the Southern Flank site. The buoy design, sensors and mooring configuration is presented and discussed below, and the data obtained is presented and discussed in an accompanying report \"U.S. GLOBEC Georges Bank Long-Term Moored Program: Data Report.\" (December 2005 WHOI-2005-11; \" <a href=\"http://globec.whoi.edu/globec-dir/data_doc/WHOI-2005-11.pdf\" target=\"blank\"><em>U.S. GLOBEC Georges Bank Long-Term Moored Program: Part 1 - Mooring Configuration</em></a>\" by J.D.

<p>\"Long-term moorings were deployed on Georges Bank from the fall of 1994 through the summer of 1999. The Southern Flank site was occupied all years, the Crest just the first and the Northeast Peak the second, fourth and fifth years. Not all depths were occupied by all sensors at all times.\" (DRAFT REPORT - 27 April 2005, WHOI-2005-XX, \"<a href=\"http://globec.whoi.edu/globec-dir/data_doc/GLOBEC-GB_moorings-2_Apr05_DRAFT.pdf\" target=\"blank\"><em>U.S. GLOBEC Georges Bank Long-Term Moored Program: Part 2 - Yearly Data Summary and Report</em></a>\" J.D.

作为美国全球海洋生态系统动力学研究（U.S. GLOBEC）西北大西洋/乔治浅滩项目的组成部分，研究团队在乔治浅滩部署了锚系观测系统，作为该项目大范围调查模块的一部分，用于量化该区域物理与生物特征的时间变异性。该观测阵列包含位于南侧陆坡的主锚系站点——该站点在整个5年野外项目周期内均持续运行——此外还在混合充分的乔治浅滩脊区（Crest）以及东北海峰的鳕鱼/黑线鳕产卵区布设了次级锚系站点，次级站点搭载的传感器数量更少、运行时长更短。研究人员以5米为间隔测量温度与电导率（盐度），采用垂直分辨率为1米的声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）获取流速剖面，并在10米和40米水深处布设生物光学包，用于测量荧光值、光透射率以及光合有效辐射（photosynthetically active radiation, PAR）。南侧陆坡站点还开展了海底压力观测。下文将对浮标设计、传感器配置以及锚系系统架构进行阐述与讨论，所获观测数据的详细说明则收录于配套报告"U.S. GLOBEC 乔治浅滩长期锚系项目：数据报告"（2005年12月，伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）-2005-11；参见J.D.

乔治浅滩的长期锚系观测系统部署周期为1994年秋季至1999年夏季。其中南侧陆坡站点在全部观测年份均持续运行，乔治浅滩脊区站点仅在第1年布设，东北海峰站点则在第2、4、5年运行。并非所有传感器在全部时段均可覆盖所有观测水深。（资料来源：2005年4月27日草案报告，WHOI-2005-XX，参见J.D. Irish、R.C. Beardsley、M. Caruso、R.
