Darwin Harbour Habitat Mapping Program: Predicted surface of Total Sediment Metabolism

This resource contains a predicted total sediment metabolism 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 sediment metabolism 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.本数据集作为达尔文港（Darwin Harbour）与拜诺港（Bynoe Harbour）海底基线测绘项目的组成部分，包含大达尔文港区域的沉积物总代谢预测网格数据。本项目由INPEX牵头的伊奇斯液化天然气（Ichthys LNG）项目所提供的补偿资金资助给北领地政府环境与自然资源部（NTG-DENR），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。本项目旨在通过整理与采集基线数据，提升对达尔文港及拜诺港海域海洋环境的认知，所获数据可用于制作专题生境地图及相关信息，为海洋资源管理决策提供支撑。本次沉积物总代谢预测网格数据由GA、AIMS与NTG-DENR在2011至2017年间开展的多项勘测数据整合而成，涵盖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、GA0359（Radke等，2018）的勘测成果，同时纳入了GA、AIMS、NTG-DENR与达尔文港务局（Darwin Port Authority）此前开展的GA4425与GA0333勘测数据。
