East Antarctica Monitoring Program

Monitoring variability in predator diets can highlight key parameters for understanding and managing marine ecosystems. Penguin diets provide useful indicators of ecosystem variability and several species, including Adélie penguins (Pygoscelis adeliae)…

We present a synthesis of marine soft sediment macrofaunal communities from the Vestfold Hills, East Antarctica, spanning historical data (1978–1982) and recent surveys from 47 locations (2010–2021). We examined relationships between environmental conditions…

Invasive species are a significant threat to marine ecosystems, contributing to biodiversity loss and ecosystem … changes. Biofouling, the accumulation of aquatic organisms on vessel hulls, is one of the main pathways for … invasive species worldwide…

Airborne environmental DNA (airborne eDNA) analysis leverages the globally ubiquitous medium of air to deliver broad species distribution data and support ecosystem monitoring across diverse environments. As this emerging technology matures…

Population monitoring provides information on species conservation status. We reassess the status of the southern elephant seal population at Macquarie Island. The number of cows on the isthmus, ~20% of the total population, correlated with counts for the whole island (i.e.

Human influence on Antarctic marine ecosystems is a growing concern, despite limited … information being available. This study investigated the coastal meiofauna and environmental … parameters of 10 locations, 4 of which served as reference points (OB1, OB2, OB3, and McGrady)…

1. Marine invasive species can cause irreparable change in new environments, though not all non-native … species inevitably cause negative impacts to recipient … ecosystems.

Microbial communities in Antarctic marine sponges have distinct taxonomic and functional profiles due to low temperatures, seasonal days and nights, and geographic isolation. These sponge holobionts contribute to nutrient cycling, structural habitat formation, and benthic ecosystem resilience.

The Southern Ocean surrounding Antarctica harbours some of the most pristine marine environments remaining, but is increasingly vulnerable to anthropogenic pressures, climate change, and invasion by non-native species.

Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been … developed to evaluate population genetic trends without necessarily collecting new genetic data. Such "genetic diversity … indicators" enable rapid…

Terrestrially breeding marine predators have experienced shifts in species distribution, prey availability, breeding phenology, and population dynamics due to climate change worldwide. These central-place foragers are restricted within proximity of their breeding colonies during the breeding season…

Genomic adaptation and introgression can occur during the speciation process, enabling species to diverge in their frequencies of adaptive alleles or acquire new alleles that may promote adaptation to environmental changes.

Baseline characterisation of the acoustic underwater environment is integral to understanding changes in the soundscape of a location. We used passive acoustic monitoring to investigate the soundscape of a seasonally ice-covered…

The distribution of New Zealand sea lions is typically localised to New Zealand and its remote subantarctic islands. However, non-resident male sea lions were seen on Macquarie Island, 650 km from their nearest natal islands, in all months of all years from 1965 to 1980.

The capacity sharing approach of the Scientific Committee on Oceanic Research (SCOR) focuses on supporting opportunities for individual ocean scientists and students within SCOR's portfolio of scientific activities and through targeted capacity development opportunities (Morrison et al.…

Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed…
