British Virgin Islands multibeam backscatter data

A multibeam echosounder survey was undertaken in July/August 2014 as part of
the Darwin Plus funded project (DPLUS026) in the British Virgin Islands. The
survey was undertaken from the MV Rhone Ranger, owned by the National Parks
Trust of the Virgin Islands. The survey suite consisted of the following
items: Teledyne-Reson T20-P multibeam echosounder, Applanix POS MV Wavemaster
Inertial Motion Unit with Fugro GPS corrections, SAIV SD-204 CTD profiler,
PDS2000 and Pos-Pac data acquisition software.

This dataset is a raster file in *.img format which shows an image and
contains backscatter intensity values (in decibels) across the survey area.

2014年7月至8月期间，作为达尔文计划（DPLUS026）资助项目的一部分，在英国维尔京群岛进行了一次多波束测深仪调查。该调查由维尔京群岛国家公园信托公司拥有的MV Rhone Ranger号船只执行。调查设备包括以下项目：泰雷德因-雷松T20-P型多波束测深仪、Applanix POS MV Wavemaster惯性运动单元配备福格罗GPS校正、SAIV SD-204 CTD剖面仪以及PDS2000和Pos-Pac数据采集软件。本数据集为*.img格式的栅格文件，显示图像并包含调查区域内后向散射强度值（以分贝为单位）。
