These data were derived from the measurement of sediment grain sizes from seabed samples collected as part of a baseline habitat mapping program for the Darwin Harbour region, including Bynoe Harbour. This project was funded through offset funds provided by 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 sediment samples were collected during multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017. A total of 499 samples are reported on from 489 stations with all grain size data published in the Marine Sediments Database (MARS).
