Darwin Harbour Habitat Mapping Program: Mixed benthos habitat

This resource contains a maximum likelihood map of five benthic habitat 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 a maximum likelihood map of five benthic habitat 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 a previous survey GA0333 collected by GA, AIMS and NTG-DENR.

本数据集包含大达尔文港区域的5种底栖生境最大似然图，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。本项目由INPEX牵头的伊契斯液化天然气（LNG）项目提供补偿资金，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（GA）与澳大利亚海洋科学研究所（AIMS）共同出资参与。本测绘项目旨在通过整合与采集基线数据，生成专题生境图及相关信息，为达尔文港与拜诺港海域的海洋资源管理决策提供支撑，以深化对该区域海洋环境的认知。本次生成的5种底栖生境最大似然图，源自2011至2017年间GA、AIMS与NTG-DENR开展的多份调查数据的整合，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、GA0359（Radke等，2018），同时纳入了此前由GA、AIMS与NTG-DENR完成的GA0333调查数据。
