Beagle Marine Park bathymetry data 2018

This resource includes bathymetry data for Beagle Marine Park (Bass Strait) collected by Geoscience Australia (GA) and the Institute for Marine & Antarctic Studies (University of Tasmania; UTAS) during the period 17 - 26 June 2018 on the RV Bluefin. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and UTAS. The purpose of the project was to build baseline information for benthic habitats in the Beagle Marine Park that will support ongoing environmental monitoring within the South-east Marine Park Network as part of the 10-year management plan (2013-2023). Data acquisition for the project was completed during three separate voyages: Phase 1 - Seabed mapping by multibeam sonar; Phase 2 - Seabed imagery acquisition by Autonomous Underwater Vehicle, and sediment sampling; Phase 3 - Survey of demersal fish communities using Baited Remote Underwater Video (BRUVs). This dataset from Phase 1 comprises 11 bathymetry grids derived from multibeam sonar data gridded at 1 m spatial resolution, covering a combined area of 364 km2.

本数据集涵盖巴斯海峡比格尔海洋公园的海底测深数据，由澳大利亚地质调查局（Geoscience Australia, GA）与塔斯马尼亚大学海洋与南极研究所（Institute for Marine & Antarctic Studies, University of Tasmania, UTAS）于2018年6月17日至26日搭乘“蓝鳍号”科考船采集完成。

本次勘测为合作项目，由国家环境科学项目海洋生物多样性中心资助，澳大利亚地质调查局与塔斯马尼亚大学共同投入经费。本项目旨在为比格尔海洋公园的底栖生境建立基线信息，以支撑东南海洋公园网络内的持续环境监测工作——该网络是2013-2023年十年管理计划的组成部分。

本项目的数据采集分为三个独立航次完成：
第一阶段：多波束声呐海底测绘；
第二阶段：自主水下航行器（Autonomous Underwater Vehicle, AUV）海底图像采集与沉积物取样；
第三阶段：利用诱饵式远程水下视频（Baited Remote Underwater Video, BRUVs）开展底栖鱼类群落勘测。

本第一阶段数据集包含11幅由多波束声呐数据生成的测深网格数据，空间分辨率为1米，总覆盖面积达364平方千米。
