Ship-based Trackline Geophysical Data (MGD77) acquired during the Nathaniel B. Palmer expedition NBP0202 (2002)

This data set was acquired with a ship-based Gravimeter and Subbottom Profiler and Gravimeter during Nathaniel B. Palmer expedition NBP0202 conducted in 2002 (Chief Scientist: Dr. Peter Wiebe). These data files are of MGD77 format and include Bathymetry, Gravity (Field and Free Air Anomaly) data that were processed during the cruise. Data were acquired as part of the project(s): SO GLOBEC: Water-column phytoplankton primary productivity, SO GLOBEC: Water-column nutrient analysis, SO GLOBEC: Mesoscale Circulation, Tides, and Mixing, SO GLOBEC: Krill distribution, physiology, and predations; Copepod prey abundance, SO GLOBEC: Seabird distribution and abundance, SO GLOBEC: Hydrographic modeling, both biological and physical, SO GLOBEC: Zooplankton distribution, abundance in the water column and sea-ice/water column boundary, and SO GLOBEC: Mysticete Whale Acoustic Census in the GLOBEC West Antarctic Project Area, and funding was provided by NSF grant(s): OPP01-96489, ANT99-10007, OPP99-10102, OPP99-10175, and OPP99-11731

本数据集采集自2002年执行的纳撒尼尔·B·帕尔默号（Nathaniel B. Palmer）考察航次NBP0202，期间依托船载重力仪（Gravimeter）与浅地层剖面仪（Subbottom Profiler）完成数据采集，首席科学家为Peter Wiebe博士。本次采集的数据文件采用MGD77格式，包含经本航次处理完成的测深数据、重力数据（含野外重力与自由空气异常）。本数据隶属于以下南大洋全球海洋生态系统动力学研究（SO GLOBEC）相关项目：水柱浮游植物初级生产力研究、水柱营养盐分析研究、中尺度环流与潮汐混合过程研究、磷虾分布及生理与捕食行为研究、桡足类猎物丰度研究、海鸟分布与种群丰度研究、生物与物理海洋水文建模研究、浮游动物在水柱及海冰-水柱界面的分布与种群丰度研究，以及南极西部GLOBEC项目海域须鲸声学普查研究。本研究获得美国国家科学基金会（NSF）的以下项目资助：OPP01-96489、ANT99-10007、OPP99-10102、OPP99-10175及OPP99-11731。
