Bynoe Harbour Habitat Mapping Survey 2016: High resolution bathymetry grid

This resource contains multibeam bathymetry data for Bynoe Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources) during the period between 3 and 27 May 2016 on the RV Solander (survey SOL6432/GA04452). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Environment and Natural Resources, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions. The specific objectives of the survey were to: 1. Obtain high resolution geophysical (bathymetry) data for Bynoe Harbour; 2. Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for Bynoe Harbour; and 3. Collect tidal data for the survey area. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. This dataset comprises multibeam bathymetry data.

本资源包含2016年5月3日至27日期间，由澳大利亚地球科学局（Geoscience Australia，GA）、澳大利亚海洋科学研究所（Australian Institute of Marine Science，AIMS）及北领地政府环境与自然资源部（Northern Territory Government Department of Environment and Natural Resources）在索兰德号考察船（RV Solander）上开展的SOL6432/GA04452调查中采集的拜诺港（Bynoe Harbour）多波束水深测量数据（multibeam bathymetry data）。

该项目得以实施，得益于由INPEX牵头的Ichthys液化天然气项目（INPEX-led Ichthys LNG Project）向北领地政府环境与自然资源部提供的补偿资金，以及澳大利亚地球科学局和澳大利亚海洋科学研究所的共同投资。

此四年计划（2014-2018）的目标是通过整理与收集基线数据（baseline data），提升达尔文及拜诺港区域海洋环境的认知水平，从而生成支撑海洋资源管理决策的专题生境图（thematic habitat maps）。

本次调查的具体目标为：1. 获取拜诺港的高分辨率地球物理（水深测量，bathymetry）数据；2. 表征拜诺港的基底（substrates）特征，包括声学反向散射特性（acoustic backscatter properties）、粒度（grainsize）及沉积物化学性质（sediment chemistry）；3. 收集调查区域的潮汐数据（tidal data）。

调查期间获取的数据包括：多波束声呐水深测量数据（multibeam sonar bathymetry）与声学反向散射数据；海底沉积物物理样本、抓斗采样点的水下摄影与视频，以及包含潮汐数据和声速剖面（sound velocity profiles）在内的海洋学信息。

本数据集包含多波束水深测量数据。调查的详细说明见：Siwabessy, P.J.W., Smit, N., Atkinson, I., Dando, N., Harries, S., Howard, F.J.F., Li, J., Nicholas W.A., Picard, K., Radke, L.C., Tran, M., Williams, D. and Whiteway, T. 2016.
