Darwin Harbour Habitat Mapping Program: Predicted surface of Total Reactive Chlorins in sediments

This resource contains a predicted total reactive chlorins 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 reactive chlorins 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总反应性叶绿素（total reactive chlorins）预测栅格数据。本项目资金由INPEX牵头的伊契斯液化天然气（Ichthys LNG）项目提供的抵偿资金拨付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（GA）与澳大利亚海洋科学研究所（AIMS）共同出资配套。本测绘项目旨在通过整合与采集基线数据，编制专题生境地图并提供相关信息，以支撑海洋资源管理决策，从而深化对达尔文港与拜诺港区域海洋环境的认知。本次预测得到的总反应性叶绿素栅格数据，整合了2011至2017年间GA、AIMS与NTG-DENR开展的多份调查数据，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），同时补充了GA、AIMS、NTG-DENR与达尔文港务局此前采集的GA4425与GA0333两份调查数据。
