Ship-based Trackline Geophysical Data (MGD77) from the Drake Passage acquired during the Nathaniel B. Palmer expedition NBP0908 (2009)

This data set was acquired with a ship-based Gravimeter and Subbottom Profiler during Nathaniel B. Palmer expedition NBP0908 conducted in 2009 (Chief Scientist: Dr. Teresa Chereskin). 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): Collaborative Research: Dynamics and transport of the Antarctic Circumpolar Current in Drake Passage, and funding was provided by NSF grant(s): ANT06-36493.

本数据集依托船载重力仪（Gravimeter）与浅地层剖面仪（Subbottom Profiler）采集于2009年执行的内森尼尔·B·帕尔默（Nathaniel B. Palmer）号科考航次NBP0908，本次航次首席科学家为Teresa Chereskin博士。本数据集的文件格式为MGD77，包含本次航次处理得到的水深（Bathymetry）、重力场与自由空气异常（Free Air Anomaly）数据。本次数据采集工作隶属于合作研究项目《德雷克海峡南极绕极流的动力学与输运过程》，研究经费由美国国家科学基金会（National Science Foundation, NSF）资助的ANT06-36493号项目提供。
