Darwin Harbour Habitat Mapping Program: Predicted surface Chlorin Index in sediments

This resource contains a predicted chlorin index 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 chlorin index 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预测叶绿素指数（chlorin index）网格数据，该数据为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牵头的伊契斯液化天然气（Ichthys LNG）项目向北领地政府环境与自然资源部（Northern Territory Government’s Department of Environment and Natural Resources, NTG-DENR）提供补偿资金资助，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）共同出资。本项目旨在通过整理与收集基线数据，深化对达尔文港及拜诺港海域海洋环境的认知，以生成专题生境地图及相关信息，为海洋资源管理决策提供支撑。该预测叶绿素指数网格数据源自2011年至2017年间GA、AIMS与NTG-DENR开展的多项勘测数据汇编，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），并补充了此前由GA、AIMS、NTG-DENR与达尔文港务局开展的GA4425与GA0333勘测数据。
