Ship-based Trackline Geophysical Data (MGD77) from the Drake Passage acquired during the Nathaniel B. Palmer expedition NBP0812 (2008)

This data set was acquired with a ship-based Gravimeter and Subbottom Profiler during Nathaniel B. Palmer expedition NBP0812 conducted in 2008 (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): Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage, and funding was provided by NSF grant(s): ANT06-36493

本数据集采集于2008年执行的内森尼尔·B·帕尔默号（Nathaniel B. Palmer）科考航次NBP0812，搭载船载重力仪（ship-based Gravimeter）与浅地层剖面仪（Subbottom Profiler）完成数据采集，本次航次首席科学家为特雷莎·切雷斯金（Teresa Chereskin）博士。本数据集文件采用MGD77格式，包含本次航次处理得到的水深测量（Bathymetry）数据，以及重力场（Field）和自由空气重力异常（Free Air Anomaly）两类重力数据。本数据集隶属于“德雷克海峡南极绕极流动力学与输运（Dynamics and Transport of the Antarctic Circumpolar Current in Drake Passage）”研究项目，该项目由美国国家科学基金会（National Science Foundation, NSF）通过编号为ANT06-36493的资助项目提供经费支持。
