Understanding Antarctic and Arctic marine ecosystems by exploring biodiversity and resilience to environmental change is critical for making policy decisions that will lead to effective stewardship and sustainable management of marine resources. This strand of research combines existing long-term data with new field-based and experimental observations to explore the impact of environmental change on marine ecosystems.
Seabirds are amongst the most globally threatened birds, often as a consequence of incidental mortality (bycatch) in fisheries [1] [2]. At South Georgia, wandering albatrosses have declined since the 1970s [3], and are listed …
Until the last decade, South Georgia held the third largest population of black-browed albatrosses at any island group (Phillips et al. 2016) [4]. However, assuming trends at surveyed sites are …
CUPIDO aims to address: what is the role of zooplankton in promoting the transport of plastic in the ocean?
and how this plastic transport interferes with zooplankton’s ability to store carbon in the deep ocean?
The commercial fishery for Antarctic krill (Euphausia superba) operates in the southwest Atlantic, in particular along the west Antarctic Peninsula, and over the shelf breaks of the South Shetland Islands, …
Wandering albatrosses are threatened by bycatch. Populations at South Georgia have declined catastrophically since the 1960s due to incidental mortality (bycatch) in fisheries (Pardo et al. 2017) [1]. This led …
A fishery for Antarctic krill (Euphausia superba) operates over the shelf breaks of the South Orkney, South Shetland and South Georgia archipelagos [8]. Krill is an important food source for …
The grey-headed albatross is listed as Endangered in the IUCN Red List of Threatened Species because of a decline since the 1970s of the largest global breeding population, which is …
On 12 July 2017, the Larsen-C Ice Shelf calved one of the largest iceberg originating from the Antarctic Peninsula ever recorded. As iceberg A68 moves north, it leaves behind an …
Three species of penguin breed on Signy Island: Adélie penguins (Pygoscelis adeliae), chinstrap penguins (Pygoscelis antarcticus) and gentoo penguins (Pygoscelis papua). These species have contrasting breeding and foraging strategies and …
Two species of penguin breed on Bird Island: macaroni penguins (Eudyptes chrysolophus) and gentoo penguins (Pygoscelis papua). These species have contrasting breeding and foraging strategies and ranging behaviour. Gentoo penguins …
