Beagle Marine Park bathymetry survey 2018 (GA0364)

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 TV 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 366 km2.

本数据集包含采集自巴斯海峡比格尔海洋公园的水深测量（bathymetry）数据，由澳大利亚地球科学局（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日期间，搭乘“蓝鳍号”（TV Bluefin）科考船完成采集。
本次调查依托一项合作项目开展，该项目由国家环境科学项目海洋生物多样性中心资助，澳大利亚地球科学局与塔斯马尼亚大学共同提供配套投入。
本项目旨在为比格尔海洋公园的底栖生境建立基础调查数据，以支撑东南海洋公园网络内的常态化环境监测工作，该监测为2013-2023年十年管理计划的组成部分。
本项目的数据采集分三次独立航次完成：第一阶段——利用多波束声呐开展海底测绘；第二阶段——通过自主水下航行器（Autonomous Underwater Vehicle, AUV）采集海底影像并进行沉积物取样；第三阶段——借助遥控水下诱饵摄像系统（Baited Remote Underwater Video, BRUVs）开展底层鱼类群落调查。
本第一阶段数据集包含11幅由多波束声呐数据生成的水深网格，空间分辨率为1米，总覆盖面积达366平方千米。
本次调查的详细报告参见：Barrett, N.、Monk, J.、Nichol, S.L.、Falster, G.、Carroll, A.、Siwabessy, J.、Deane, A.、Picard, K.、Dando, N.、Hulls, J.、Evans, H. 2019年发布的《比格尔海洋公园事后调查报告：东南海洋公园网络》，该报告为提交给国家环境科学项目海洋生物多样性中心的专项报告。
