Surficial sediment data along the shoreface and inner continental shelf of western Victoria, Australia

A comprehensive dataset of 138 surficial sediment samples retrieved from the shallow marine waters of six secondary compartments off the western coast of Victoria, Australia, is presented. Samples were collected between October 2018 and November 2020 at water depths ranging from four to 55 m using Shipek and Van Veen grabs. Sampling design tar-geted unconsolidated areas of the seafloor based on bathy-metric and seafloor habitat data. Retrieved sediments were subsampled and subject to grain size analysis using a combi-nation of dry sieving and laser diffraction methods, carbon-ate and organic matter content determination via Loss-on -Ignition, colour description using a Munsell chart, and round-ness analysis using microscopic photography. This dataset, the most comprehensive surficial shallow water sedimentary record of the Otway Shelf, serves as a benchmark to un-derstand sediment dynamics and conectivity along the coast, and can be used in environmental and engineering studies to support a range of management decisions.(c) 2022 The Authors.
