Arafura Marine Park survey (SOL7491/GA0366)

This resource includes bathymetry data for Arafura Marine Park (Arafura Sea) collected by Geoscience Australia (GA) and the Australian Institute of Marine Science during the period 2 – 15 November 2020 on the RV Solander. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and AIMS. The purpose of the project was to build baseline information for benthic habitats in Arafura Marine Park that will support ongoing environmental monitoring within the North Marine Park Network as part of the 10-year management plan (2018-2028). Data acquisition for the project included multibeam bathymetry and backscatter for two areas (Money Shoal and Pillar Bank), seabed samples and underwater imagery of benthic communities and demersal fish. This bathymetry dataset contains a 6 m resolution 32-bit geotiff of the survey areas produced from the processed EM2040C Dual Head system using CARIS HIPS and SIPS software. A detailed report on the survey is provided in: Picard, K. Stowar, M., Roberts, N., Siwabessy, J., Abdul Wahab, M.A., Galaiduk, R., Miller, K., Nichol, S. 2021.

本数据集包含阿拉弗拉海海洋公园（Arafura Marine Park，阿拉弗拉海）的水深测量数据，该数据由澳大利亚地球科学局（Geoscience Australia, GA）与澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）于2020年11月2日至15日期间，搭载索兰德号科考船（RV Solander）采集获取。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，并由GA与AIMS共同投入配套经费。本项目旨在为阿拉弗拉海海洋公园的底栖生境建立本底信息档案，以支持北海洋公园网络内的持续环境监测工作，该网络是2018-2028年十年管理计划的组成部分。本次数据采集涵盖两个区域（莫尼浅滩Money Shoal与皮勒尔浅滩Pillar Bank）的多波束水深测量（multibeam bathymetry）与反向散射（backscatter）数据、底质样品，以及底栖群落和底栖鱼类的水下影像。本水深数据集包含勘测区域的6米分辨率32位GeoTIFF格式数据，该数据由经过处理的EM2040C双探头系统（EM2040C Dual Head system）通过CARIS HIPS and SIPS软件生成。本次勘测的详细报告参见：Picard, K.、Stowar, M.、Roberts, N.、Siwabessy, J.、Abdul Wahab, M.A.、Galaiduk, R.、Miller, K.、Nichol, S. 2021年发布的《阿拉弗拉海海洋公园勘测后报告》，提交给国家环境科学项目海洋生物多样性中心。
