A review of peer-reviewed publications was undertaken, 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 (https://www.ausmap.org/). This dataset summarises basic information about the microplastics studies: the location of the study; if the study focused on water, sediment or biota; the type of biota (for biotic studies); and the DOI of the publication. Although the primary focus of this study was restricted to southeastern Australia, studies collated from other regions have also been included in this dataset. The outcomes of the literature review for other regions (QLD, NT, SA, WA, Tas) should not be considered comprehensive.

Dive surveys were conducted in 2014 and the same sites resurveyed annually until 2022 (excluding 2021), to establish a baseline and monitor the status of the critically endangered spotted handfish (Brachionichthys hirsutus) population. This dataset is a summary of all surveys season 2014 to 2022 (excluding 2021) in which the 11 sites across the Derwent Estuary and D'Entrecasteaux Channel were assessed. The data describes the search effort (transect length, swathed area) and counts of handfish observed on each transect, including size measurements (total length) and depth records for each sighted fish.

This metadata record provides a brief overview of the National Environmental Science Program (NESP) Marine and Coastal (MaC) Hub. The record acts as an aggregation point for all NESP Marine and Coastal Hub data collections and projects developed as part of this research program. The National Environmental Science Program (NESP) is a long-term commitment by the Australian Government to environment and climate research. The first phase invested $145 million (2014-15 to 2020-21) into 6 research hubs. The second phase invests $149 million (2020-21 to 2026-27) into 4 new research hubs. The program builds on its predecessors – the National Environmental Research Program (NERP) and the Australian Climate Change Science Programme (ACCSP) – to support decision-makers to understand, manage and conserve Australia’s environment by funding world-class biodiversity and climate science. The Marine and Coastal Hub is a collaborative partnership supported by funding from the Australian Government administered by the Department of Climate Change, the Environment, Energy and Water (DCCEEW) - previously Department of Agriculture, Water and the Environment (DAWE). The current NESP funding program runs from 2021 to 2027. The Marine and Coastal Hub is co-administered by the University of Tasmania (UTAS), and the Reef and Rainforest Research Centre (RRRC). The Marine and Coastal Hub delivers: • applied research to support management of Australia’s marine and coastal environments including estuaries, coast, reefs, shelf and deep-water • targeted biodiversity and taxonomy products to support efficient system monitoring • environmental monitoring systems and decision-support tools. Research products from the NESP Marine and Coastal Hub are available from https://nespmarinecoastal.edu.au and the Australian Ocean Data Network catalogue (http://catalogue.aodn.org.au)

Aerial surveys of southern right whales (Eubalaena australis) were undertaken off the southern Australian coast to monitor the recovery of this endangered species following extreme 19th and 20th Century commercial whaling. The aerial survey was undertaken in the coastal waters from Perth (Western Australia) to Ceduna (South Australia) between the 12th and 19th August 2022, to maintain the annual series of surveys and inform the long-term population trend. The survey resulted in a total 526 whales sighted, consisting of 247 cow-calf pairs, 31 unaccompanied adults and 1 yearling. The ‘western’ population of southern right whales in Australian waters is increasing in size (~5.3% per year based on female/calf pairs and a population estimate of 2675 whales) based on the long-term population trend data from the annual aerial surveys. This represents the majority of the Australian population given the very low numbers in the ‘eastern’ population. The 2022 surveys recorded the lowest number of unaccompanied animals (i.e. males and females without a calf) ever throughout the time-series of the annual aerial surveys since 1993 when survey coverage between Cape Leeuwin and Ceduna first began. Across this time series, there is a particularly notable decline in sightings of unaccompanied animals over the past five years. It is currently unclear what factors account for the decline in these sightings or may influence the variation in numbers of unaccompanied animals on the southern Australian coast. Lower than expected counts in the long-term data may provide evidence of a slowing population growth rate, which can only be assessed by continued annual population surveys to assess population trend data.

Seagrass beds are a dominant marine ecosystem of Tayaritja (the Furneaux Group of Islands) in the north-eastern waters off Tasmania. Historical coarse mapping has indicated extensive beds of Posidonia, Amphibolis, Heterozostera, and Zostera species, potentially comprising some of the largest and deepest seagrass extents found in temperate Australian waters. However, limited data on the distribution and ecological value of these seagrass habitats represents a significant knowledge gap in understanding Australia's wetland natural assets. This project mapped the extent, ecological composition, population structure, and blue carbon value of seagrass beds around Tayaritja. The study area focused on the coastal waters surrounding Flinders Island in the western Furneaux Group, with mapping extending from the high tide line to the depth limit of reliable optical detection (approximately 30 m), based on analysis of field data and satellite imagery capabilities in the region. The field validation component of this study involved deployment of benthic video platforms to capture imagery of seagrass beds and associated ecosystems. A field campaign deployed a Benthic Observation Survey System (BOSS) and unBaited Remote Underwater stereo-Video system (stereo-uBRUV) at approximately 400 locations to collect photoquadrats and validate remote sensing outputs. Imagery annotation was conducted in the SQUIDLE+ platform. The approach developed through this study contributed to the creation of the NESP Standard Operating Procedure (SOP) for Seagrass Mapping using Optical Remote Sensing (https://sustainabledevelopmentreform.github.io/nesp-sop-seagrass-mapping).. See the "Lineage" section of this record for full methodology of field collection techniques. See associated dataset https://doi.org/10.25959/e4s6-ge74 for habitat maps derived from field validation and remote sensing inputs.

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Research needs for assessment and monitoring of nutrients, chemicals and antimicrobials in the marine environment". No data outputs were generated by this project. -------------------- Coastal water quality is threatened by an increasing volume of chemicals produced and used in our modern lives. These chemicals are commonly incorporated into pharmaceuticals and household items, and subsequently discharged into coastal areas from a broad range of point sources. Recently emerging contaminants include a variety of chemical (e.g. heavy metals, pharmaceuticals, pesticides, nutrients) and microbiological (e.g. pathogens, antibiotic resistant microbes) sources that are discharged in sewage, stormwater, estuarine flows and industrial wastes. For many of these chemicals, our understanding of their environmental concentrations and biological effects is limited. When new scientific information emerges to suggest that a particular contaminant may be hazardous, this is refered to as a contaminant of emerging concern (CEC). There is limited data about the environmental occurrence and biological effects of CECs, but emerging research suggests they have the capacity to be toxic. With an increasing list of CECs detected in the environment, important questions remain unanswered around which contaminants and scientific knowledge gaps should be prioritised. This desktop study engaged CEC stakeholders from academic research, government, water utilities, and non-government organisations to collaboratively identify priority CEC issues in Australia’s marine ecosystems. The project delivers a risk-based framework for future CEC research directions and water quality management priorities. Outputs • Final Project Report [written]

Fish annotations of stereo Baited Remote Underwater Video 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 EventMeasure using standard operating procedures for the annotation of remote stereo imagery.

The Parks Australia Management Effectiveness (ME) system - previously MERI - is underpinned by a controlled, common language that provides a nationally consistent lexicon for a) Natural, cultural, and heritage values; (b) Social, cultural, and economic benefits; (c) Activities and anthropogenic pressures; and (d) Biophysical, and social and economic drivers. The Natural Values component of the common language is defined at three levels: 1) ecosystem complexes; 2) ecosystems; and 3) ecosystem components. This map shows the Ecosystems (tier 2) component of the Natural Values, and delineates features by habitat and depth for the Australian Exclusive Economic Zone (EEZ). This version (2022) of the National Values Ecosystems dataset uses Geoscience Australia's 250m resolution Australian Bathymetry and Topography Grid, 2009 (https://dx.doi.org/10.4225/25/53D99B6581B9A) as the basis for the map. See Hayes et al. 2021 and Dunstan et al. 2023 for a full definition of Natural Values Ecosystem terms, input datasets used, and processing steps involved with the creation of this map. Note that this dataset uses a combination of input data sources and interpolates where data gaps exist. The common language adopts a functional, largely geo-physical perspective to define surrogates for marine ecosystems. This dataset is not a substitute for a validated habitat map (see Seamap Australia National Benthic Habitat Layer: https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a), but has a national coverage and provides valuable broad-scale categorisation of marine ecosystems in Australian waters. ***An updated version of this data product is available - see https://doi.org/10.25959/7SXA-DX47***

The Black Rockcod (Epinephelus daemelii) is a large, slow-growing, long-lived reef fish that occurs in Australia along the coast of New South Wales, including at Lord Howe Island. Populations of black rockcod have been significantly reduced here due to overfishing, accidental hooking, and loss or degradation of estuarine and intertidal nursery habitats. As a result, the species is listed as ‘Vulnerable’ under both the Commonwealth Environmental Protection and Biodiversity Conservation Act 1999 and the NSW Fisheries Management Act 1994. Despite having been protected from fishing in NSW since 1983, black rockcod are still taken illegally, or caught incidentally and released, which can lead to mortality post-release from embolism. Its protection status results from concerns of population declines across its range. The NSW Government has identified long-term population monitoring as a a high priority for the species’ recovery plan. Broadscale surveys of black rockcod were first conducted using the diver Underwater Visual Census (UVC) technique in 2009-11 when 83 sites were sampled from Port Stephens to Cook Island in far northern NSW, including the waters of Lord Howe Island. This NESP Marine and Coastal Hub project 3.14 funded the repeat of these broadscale surveys in 2023, with 8 additional sites (91 total) sampled using the same technique. For each black rockcod sighting, the length of the fish was visually estimated by divers, and also filmed using a diver stereo camera system where possible to obtain an exact length measurement. Other attributes recorded included the habitat the fish was found in, if the sighting was cryptic (i.e. hidden or camouflaged), and the depth of the sighting. Based on the broadscale survey sites in 2009-11, a subset of 19 key Black rockcod survey sites along mainland NSW were established These comprised of two sites in the Cape Byron Marine Park (CBMP), five sites in the Solitary Islands Marine Park (SIMP) two sites at SW Rocks (Fish Rock), and ten sites within the Port Stephens-Great Lakes Marine Park (PSGLMP). An additional 18 key sites were established at Lord Howe Island (LHIMP) and surveyed in 2011, 2019, 2023 & 2024. These surveys involved an identical methodology to the broadscale surveys, but without the use of stereo cameras as diver estimates of fish size were shown to be reasonably similar. This NESP MaC Hub project 3.14 provided funding for the resurveying of the 37 total key sites (where weather permitted) in both 2023 and 2024. The data provided by this record includes: (1) all black rockcod sightings and measurements for broadscale sites (2023) and key sites (2023 & 2024); (2) a comparison of the counts of black rockcod recorded at broadscale sites in 2009-11 (n=83) and again in 2023 (n=91); and (3) a comparison of the count of black rockcod recorded at key monitoring sites in northern NSW (n=19) and Lord Howe Island (n=18) across monitoring years 2009-2024.
