1. Seabird species worldwide are integral to both marine and terrestrial environments, connecting the two systems by transporting vast quantities of marine-derived nutrients and pollutants to terrestrial breeding, roosting, and nesting grounds via the deposition of guano and other allochthonous inputs (e.g., eggs, feathers). 2. We conducted a systematic review and meta-analysis and provide insight into what types of nutrients and pollutants seabirds are transporting, the influence these subsidies are having on recipient environments, with a particular focus on soil, and what may happen if seabird populations decline. 3. The addition of guano to colony soils substantially increased nutrient levels compared to control soils for all seabirds studied, with cascading positive effects observed across a range of habitats. Deposited guano sometimes led to negative impacts, such a guanotrophication, or guano-induced eutrophication, which was often observed where there was an excess of guano or in areas with high seabird densities. 4. While the literature describing nutrients transported by seabirds is extensive, literature regarding pollutant transfer is comparatively limited, with a focus on toxic and bioaccumulative metals. Research on persistent organic pollutants and plastics transported by seabirds is likely to increase in coming years. 5. Studies were limited geographically, with hotspots of research activity in a few locations, but data were lacking from large regions around the world. Studies were also limited to seabird species generally listed as Least Concern on the IUCN Red List. As seabird populations are impacted by multiple threats and steep declines have been observed for many species worldwide, gaps in the literature are particularly concerning. The loss of seabirds will impact nutrient cycling at localised levels and potentially on a global scale as well, yet it is unknown what may truly happen to areas that rely on seabirds if these populations disappear. The information in this record includes three spreadsheets and R code. Descriptions are included below: - The spreadsheets contain all information extracted from the publications that were critically reviewed (n = 181). The first spreadsheet contains information regarding each publication (1 publication per row), such as study location, sampling methods. The second spreadsheet contains information about the seabird species studied in each publication (1 row per seabird species per publication). The third spreadsheet contains data for the meta-analysis (1 row per publication, except if the publication studied multiple species, then it would be 1 row per species per publication). - The R code is for the meta-analyses that were undertaken. Comments are included within the code plus detailed information can be found in the Methods section of the paper.

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).

The imagery provides representative and highlight clips from the quantitative sampling of the abundance, body size and diversity of demersal fishes baited remote underwater stereo video (stereo BRUV) in and around Tasman Fracture, Beagle, Huon and Freycinet Australian Marine Parks (AMPs). The dataset allows examination of changes in fish communities over time as part of ongoing monitoring of these AMPs. There are plans for ongoing surveys as part of Parks Australia's management of the AMPs. The methods and key findings of the work are described in detail in Monk et al. (2016) and Perkins et al. (2022).

This data is a national compilation of video clips predominantly derived from underwater video sampling techniques (e.g. BRUV, Stereo-BOSS) for quantitative sampling of abundance, body size, and diversity of demersal fishes. The curated collection also includes regional 'compilation' videos highlighting a particular marine protected area or region of interest. Current contributors to this data compilation are IMAS, UWA, Geoscience Australia and the NESP Marine Biodiversity & Marine and Coastal Hubs, with the intention that this collection will grow to encompass collections from other research organisations around Australia. As of August 2024, this dataset includes video in and around Abrolhos, Arafura, Apollo, Beagle, Bremer, Christmas Island, Cod Grounds, Coral Sea, Dampier, Eastern Recherche, Flinders, Franklin, Freycinet, Gascoyne, Geographe, Huon, Lord Howe, Montebello, Murat, Murray, Ningaloo, Oceanic Shoals, Perth Canyon, South Tasman Rise, South-west Corner, Tasman Fracture, Two Rocks, and Zeehan Australian Marine Parks (AMPs), and of Bathurst Channel in the Port Davey Marine Reserve. The dataset allows examination of changes in fish communities over time as part of ongoing monitoring of these regions. This record represents a 'parent' record of multiple collections. See individual 'child' records for more information on specific regional collections.

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).

Tidal wetlands are vulnerable to accelerated rates of sea-level rise projected by climate models. Assessing the resilience, or vulnerability, of these environments requires measurements of rates of vertical accretion, subsidence and elevation gain across a range of coastal settings. The Surface Elevation Table (SET) technique is applied globally to assess the extent of vertical adjustment of tidal wetlands to sea-level rise over decadal timescales. This enables measurement of whether wetlands are keeping pace with sea level rise (measured at tide gauges), or subsiding relative to local sea level rise and thus vulnerable to permanent inundation and loss. Australia’s network of Surface Elevation Tables is one of the most extensive in the world, consisting of over 200 benchmark monitoring stations from Westernport Bay, Victoria to Darwin Harbour, NT. This record describes the consolidated SET data collated from the Australian network (OzSET) as at 2022. This data can be used for analysing change to the elevation of wetlands wetlands at the study sites encompassed by OzSET.

Decision-makers seek to account for the socioeconomic values of environmental assets. However, understanding the available frameworks and data can be a barrier. We address this here by summarising the data used across four case studies (3 geographic regions and 3 socio-economic value frameworks) to demonstrate what data are available and how they are applied to support decisions in varied contexts. See 'Lineage' section of this record for additional methodology.
