Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface of Chlorin Index in sediments

This resource contains a predicted chlorin index 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 chlorin index 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.

本数据集包含大达尔文港区域的叶绿素指数（chlorin index）预测标准误差栅格，该成果为达尔文港与拜诺港基线海底测绘项目的组成部分。本项目资金由英佩克斯（INPEX）牵头的伊契斯液化天然气项目提供的补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（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。本项目旨在通过整合与采集基线数据，深化对达尔文港及拜诺港海域海洋环境的认知，进而生成专题生境地图与相关支撑信息，为海洋资源管理决策提供依据。本次的叶绿素指数预测标准误差栅格由澳大利亚地质调查局、澳大利亚海洋科学研究所与北领地政府环境与自然资源部在2011至2017年间开展的多项勘测数据汇总推导所得，涉及的勘测项目包括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），同时纳入了由澳大利亚地质调查局、澳大利亚海洋科学研究所、北领地政府环境与自然资源部及达尔文港务局采集的既往勘测项目GA4425与GA0333的数据。
