Ship-based Trackline Geophysical Data (MGD77) from the Ross Sea acquired during the Nathaniel B. Palmer expedition NBP0803 (2008)

This data set was acquired with a ship-based Gravimeter and Subbottom Profiler during Nathaniel B. Palmer expedition NBP0803 conducted in 2008 (Chief Scientist: Dr. Philip Bart). 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): Ross-Sea outer continental shelf morphology and near-surface stratigraphy: Quaternary ice-sheet grounding-zone migrations and stratigraphy: Quaternary ice-sheet grounding-zone migrations and the LGM dilemma., and funding was provided by NSF grant(s): ANT05-38475本数据集采集自2008年执行的Nathaniel B. Palmer号考察航次NBP0803，搭载设备为船载重力仪（ship-based Gravimeter）与海底剖面仪（Subbottom Profiler），本次航次的首席科学家为Philip Bart博士。本数据集采用MGD77格式存储，包含航次期间处理得到的水深数据（Bathymetry）、重力数据（含野外重力与自由空气异常）。本数据采集工作隶属于以下研究项目：罗斯海外大陆架地貌与近地表地层学：第四纪冰盖接地带迁移与地层学、第四纪冰盖接地带迁移与末次盛冰期（Last Glacial Maximum，简称LGM）困境。本研究获得美国国家科学基金会（National Science Foundation，简称NSF）ANT05-38475号项目资助。
