Tasmanian East Coast (GA4883)

This resource includes bathymetry data acquired during the Tasmanian East Coast bathymetry survey collected by Institute for Marine and Antarctic Studies (IMAS) University of Tasmania (UTAS) during the period 12 – 23 April 2021 on the RV Abyss using a Kongsberg Maritime EM2040C multibeam sonar (contracted from CSIRO). The Tasmanian East Coast bathymetry survey was led by Dr. Vanessa Lucieer (IMAS). The purpose of the project was to map the fine-scale spatial distribution of key abalone habitat impacted by urchins in < 25 m water depth using multibeam acoustic imagery. This dataset contains seven 0.5m-resolution 32-bit floating point geotiff files of the bathymetry in study area and transits, derived from the processed EM2040C bathymetry data, using CARIS HIPS and SIPS software.

本数据集涵盖塔斯马尼亚东海岸水深测量作业所获取的水深地形数据，该作业由塔斯马尼亚大学海洋与南极研究所（Institute for Marine and Antarctic Studies, IMAS）于2021年4月12日至23日期间执行，搭载平台为RV Abyss号科考船，采用从澳大利亚联邦科学与工业研究组织（CSIRO）租赁的Kongsberg Maritime EM2040C多波束声呐系统采集数据。
本次塔斯马尼亚东海岸水深测量作业由Vanessa Lucieer博士（IMAS）主导。本项目的研究目标为：利用多波束声学成像技术，绘制水深小于25米区域内受冠海胆属（Centrostephanus）影响的关键鲍鱼栖息地的精细空间分布格局。
本数据集包含7份分辨率为0.5米的32位浮点型地理标记图像文件格式（GeoTIFF）文件，涵盖研究区与航迹段的水深地形数据，其基于经后处理的EM2040C水深数据，使用CARIS HIPS和SIPS软件生成。
