Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface of Sediment Oxygen Demand in sediments

This resource contains a predicted sediment oxygen demand standard error 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 sediment oxygen demand standard error 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与拜诺港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需氧量（sediment oxygen demand）预测标准误差栅格数据。本项目由INPEX主导的伊奇斯液化天然气（Ichthys LNG）项目拨付补偿资金至北领地政府环境与自然资源部（NTG-DENR），并由澳大利亚地质调查局（Geoscience Australia, GA）与澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）共同参与出资。本项目的宗旨在于通过整理与采集基线数据，深化对达尔文港及拜诺港海域海洋环境的认知，以此生成专题生境地图与相关信息，为海洋资源管理决策提供坚实支撑。本次沉积物需氧量预测标准误差栅格数据，源于2011年至2017年间GA、AIMS与NTG-DENR开展的多轮勘测数据汇编，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与GA0359（Radke等，2018），同时纳入此前由GA、AIMS、NTG-DENR与达尔文港务局完成的GA4425与GA0333勘测数据。
