Ship-based Trackline Geophysical Data (MGD77) from the Southern Ocean acquired during the Nathaniel B. Palmer expedition NBP1504 (2015)

This data set was acquired with a ship-based Echosounder and Gravimeter during Nathaniel B. Palmer expedition NBP1504 conducted in 2015. These data files are of MGD77 format and include Bathymetry, Gravity Free Air Anomaly, Navigation, and Gravity Field data and were processed after data collection.

本数据集采集于2015年开展的内森尼尔·B·帕尔默号科考航次NBP1504，使用船载回声测深仪（Echosounder）与重力仪（Gravimeter）完成数据采集。本次数据文件采用MGD77格式，涵盖海底测深数据、自由空气重力异常（Gravity Free Air Anomaly）数据、导航数据与重力场（Gravity Field）数据，且已在数据采集完成后进行预处理。
