Darwin Harbour Habitat Mapping Program: Predicted surface of Total O2 Uptake in sediments

This resource contains a predicted total O2 uptake grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this 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 and information to underpin marine resource management decisions. The predicted total O2 uptake grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.

本数据集包含大达尔文港区域的总氧摄取量（O2 uptake）预测网格，该数据是达尔文港与拜诺港海底基线测绘项目的组成部分。本项目由INPEX牵头的伊奇斯液化天然气（Ichthys LNG）项目向北领地政府环境与自然资源部（NTG-DENR）提供的环境补偿资金资助，并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）共同投资。本测绘项目旨在通过整理与采集基线数据，深化对达尔文港与拜诺港海域海洋环境的认知，进而生成专题生境地图，为海洋资源管理决策提供支撑依据。本次预测的总氧摄取量网格整合了GA、AIMS与NTG-DENR在2011至2017年间开展的多轮勘测数据，包括GA0333（Siwabessy等，2015）、GA0341（Siwabessy等，2015）、GA0351/SOL6187（Siwabessy等，2016）、GA4452/SOL6432（Siwabessy等，2017）、GA0356（Radke等，2017）以及GA0358与GA0359（Radke等，2018）；同时还纳入了GA、AIMS、NTG-DENR与达尔文港务局此前采集的GA4425与GA0333勘测数据。
