A bathymetric compilation over Anvers-Hugo Trough, Perrier Trough and Palmer Deep, 1990-2017

We present extensive new bathymetric compilation over Anvers-Hugo Trough, Perrier Trough and Palmer Deep, here defined by the following bounding box: 66.15 to 64.0 W, 65.25 to 63.6 S.

This bathymetry grid was compiled from a variety of different data sources including multibeam swath bathymetry collected from scientific cruises undertaken by British Antarctic Survey (BAS), United Kingdom Hydrographic Office, or acquired during RVIB Nathaniel B. Palmer, HMS Protector and RV Maurice Ewing expeditions. The data is available as a 30m resolution grid either in a NetCDF format using WGS84 coordinate system (EPSG: 4326) or in an ESRI ASCII interchange raster format in standard Antarctic polar stereographic coordinates (EPSG 3031). The grid have been created using the MB-system mbgrid program.

我们发布了覆盖安弗斯-雨果海槽（Anvers-Hugo Trough）、佩里尔海槽（Perrier Trough）与帕尔默深海（Palmer Deep）的全新大范围水深汇编数据集，其覆盖范围由以下边界框（bounding box）界定：西经66.15°至64.0°，南纬65.25°至63.6°。

该水深栅格数据集由多类数据源汇编而成，涵盖英国南极调查局（British Antarctic Survey, BAS）、英国海道测量局（United Kingdom Hydrographic Office）开展的科学考察航次采集的多波束条带水深测量数据，以及“纳撒尼尔·B·帕尔默”号破冰科考船（RVIB Nathaniel B. Palmer）、“守护者”号皇家海军舰艇（HMS Protector）与“莫里斯·尤因”号科考船（RV Maurice Ewing）执行考察任务期间获取的相关数据。该数据集提供分辨率为30米的栅格文件，支持两种格式：采用WGS84坐标系（EPSG: 4326）的网络通用数据格式（NetCDF），以及采用标准南极极球面投影坐标系（EPSG 3031）的ESRI ASCII交换栅格格式。本栅格数据集通过MB系统（MB-system）中的mbgrid程序生成。
