  • Benthic habitat annotations of stereo Baited Remote Underwater Video (Stereo-BRUV) and panoramic drop camera imagery, were completed as part of a report funded by the NESP Marine & Coastal Hub. This report focussed on an IUCN II zone in the South-west Corner Marine Park off the 'Capes region' near Margaret River. These data were analysed in TransectMeasure using a modified version of the CATAMI scheme.

  • In this study, 34 fledgling Fairy Prions (Pachyptila turtur) recovered during a wreck event in south-eastern Tasmania in 2022 were examined for ingested plastics (number, mass, type, colour, and particle size) and body condition (e.g., wing chord length).

  • Predictions of dominant habitats were completed as part of a report funded by the NESP Marine & Coastal Hub. This report focussed on an IUCN II zone in the South-west Corner Marine Park off the 'Capes region' near Margaret River. This modelling contains data from stereo Baited Remote Underwater Video and panoramic drop camera, and was completed using the FSS-GAM package in R. Predictions are at two different scales and resolutions, one using the broad 250m resolution Geoscience Australia bathymetry and the other using a 4m resolution multibeam survey from Geoscience Australia

  • An increasing number of studies are considering Fe and ligand concentrations, providing data of trace element availability across the remote Southern Ocean region (Ardiningsih et al., 2021, Gerringa et al., 2020, Hassler et al., 2017, Thuroczy et al., 2012, Thuroczy et al., 2011, Caprara et al., 2016 and references therein). However, studies seldom focus on polar coastal environments which are especially sensitive to climate-induced changes. To anticipate how these changes may impact Fe availability, we must first understand the drivers of ligand supply to the Antarctic coast and offshore. The newly compiled Southern Ocean Ligand (SOLt) Collection includes all publicly available Fe complexation datasets for the Southern Ocean including dissolved Fe concentrations, Fe-binding ligand concentrations, and complexation capacities for 25 studies between 1995 - 2019.

  • Collection of processed BGC-Argo float profiles, used to calculate phytoplankton phenology from chlorophyll, phytoplankton carbon and nitrate.

  • We undertook a review of peer-reviewed publications focusing on coastal and marine microplastics relevant to South Eastern Australia (South Australia, Victoria, and New South Wales), as well as from ongoing citizen science programmes from AUSMAP. Here we summarise the location of the studies on microplastics, if the study focused on water, sediment or biota, and the DOI of the publication.

  • Efforts to restore Posidonia seagrass meadows in NSW are reliant on collecting beachcast fragments as collection of donor material from extant beds is prohibited. However, to maximise the collection efforts it necessary to understand where to collect fragments from and what environmental conditions (e.g. wind direction, wind strength, tidal height) increase the availability of fragments and where to collect the most healthy fragments. This data set captures the abundance of fragments at 7 sites in Gamay (Botany Bay), an area of interest for restoration of Posidonia australis. It investigates how characteristics of wind (speed and direction), tidal height and swell (height, direction) influence the availability (abundance) and health (as determined by observations of necrosis) of shoots at sites throughout Botany Bay. The Excel data workbook is comprised of two sheets: Fragments_data sheet shows the number of P. australis fragments collected at different sites, when they were collected, and the environmental conditions at collection (see data attributes section). Shoot_data sheet shows the proportion of necrosis of shoots attached to collected fragments.

  • This is a database of nature-based ("soft" or "hybrid") coastal protection projects from across Australia. The database will act as a tool to help coastal managers make informed decisions by providing as many examples as possible of where these solutions have been used, how they were used and how effective they are in different contexts. The information in this database was collected through direct engagement with coastal managers and stakeholders, a literature search, and informal internet searching.

  • Data collected from Southern Ocean phytoplankton laboratory culture experiments to examine the effect of iron limitation on the Chlorophyll fluorescence (F) to chlorophyll (Chl) ratio. Irradiance levels at which cultures were grown are indicated by the photon flux density (PFD). Growth rates of Fe limited cultures (-Fe) relative to Fe replete cultures (+Fe) are referred to as μ / μmax (unitless).

  • In March 2020 UWA and the Malgana Rangers transplanted by hand 36 pieces of Posidonia australis and Amphibolis antarctica into nearby restoration plots at Dubaut Point, Shark Bay. In March 2022 UWA went back to assess survival and shoot growth which is detailed in this dataset.
