Bynoe Harbour Habitat Mapping Survey 2016: Chlorins and porosity data for seabed sediments

This resource contains surface sediment data for Bynoe Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and Department of Land Resource Management (Northern Territory Government) during the period from 2-29 May 2016 on the RV Solander (survey SOL6432/GA4452). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, 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 outer Darwin Harbour, including Shoal Bay; 2. Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; 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 total chlorin concentrations, chlorin indices and porosity measured on seabed sediments.

本数据集收录了由澳大利亚地质调查局（Geoscience Australia, GA）、澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）以及北领地政府土地资源管理部，于2016年5月2日至29日搭载Solander号科考船（航次编号SOL6432/GA4452）在拜诺港采集的表层沉积物数据。

本项目的实施依托INPEX牵头的伊奇斯液化天然气（Ichthys LNG）项目向北领地政府土地资源管理部提供的补偿资金，以及澳大利亚地质调查局与澳大利亚海洋科学研究所的联合投入。这项为期四年（2014-2018）的计划旨在通过整理与采集基础数据，提升对达尔文港及拜诺港海域海洋环境的认知；这些基础数据可用于制作专题生境地图，为海洋资源管理决策提供支撑。

本次航次的具体目标如下：
1. 获取包括肖尔湾（Shoal Bay）在内的外达尔文港海域的高分辨率地球物理（水深测量）数据；
2. 表征外达尔文港（含肖尔湾）的底质特征，包括声学背散射特性、粒度与沉积物化学组成；
3. 采集航次区域的潮汐数据。

本次航次采集的数据包括：多波束测深声呐与声学背散射数据、海底沉积物物理样品、采样点位的水下摄影与视频影像，以及包含潮汐数据和声速剖面在内的海洋学信息。本数据集涵盖海底沉积物中测得的总氯浓度、氯指数与孔隙度数据。
