Expanding Monitoring Capacity for Potential Invasive Species in Arctic Canada With Environmental <span>DNA</span> Metabarcoding Open
To date, environmental conditions have been enough to act as an effective barrier to prevent non‐indigenous species from arriving and establishing in Arctic Canada. However, rapidly changing climatic conditions are creating more suitable h…

South Georgia marine productivity over the past 15 ka and implications for glacial evolution Open
The subantarctic islands of South Georgia are located in the Southern Ocean, and they may be sensitive to future climate warming. However, due to a lack of well-dated subantarctic palaeoclimate archives, there is still uncertainty about So…

Sea Butterflies Defend Their Homes Against an Acidic Ocean Open
We all know that carbon dioxide (CO 2 ) is produced from burning fossil fuels, and that it contributes to global warming. But have you heard about the “evil twin” of global warming, also caused by CO 2 –ocean acidification? The ocean absor…

Vertical flux of microplastic, a case study in the Southern Ocean, South Georgia Open
Estimated plastic debris floating at the ocean surface varies depending on modelling approaches, with some suggesting unaccounted sinks for marine plastic debris due to mismatches between plastic predicted to enter the ocean and that accou…

Scoping intergenerational effects of nanoplastic on the lipid reserves of Antarctic krill embryos Open
Antarctic krill (Euphausia superba) plays a central role in the Antarctic marine food web and biogeochemical cycles and has been identified as a species that is potentially vulnerable to plastic pollution. While plastic pollution has been …

Contrasting life cycles of Southern Ocean pteropods alter their vulnerability to climate change Open
Pteropods are a key part of biogeochemical cycling and epipelagic food webs in the Southern Ocean. However, shelled pteropods are vulnerable to climate change, due to their aragonite shells being particularly sensitive to ocean acidificati…

Planktic foraminifera iodine/calcium ratios from plankton tows Open
Planktic foraminifera test iodine to calcium ratios represent an emerging proxy method to assess subsurface seawater oxygenation states. Several core-top studies show lower planktic foraminifera I/Ca in locations with oxygen depleted subsu…

Latitudinal Variance in the Drivers and Pacing of Warmth During Mid‐Pleistocene MIS 31 in the Antarctic Zone of the Southern Ocean Open
Early Pleistocene Marine Isotope Stage (MIS)‐31 (1.081–1.062 Ma) is a unique interval of extreme global warming, including evidence of a West Antarctic Ice Sheet (WAIS) collapse. Here we present a new 1,000‐year resolution, spanning 1.110–…

Episodes of Early Pleistocene West Antarctic Ice Sheet Retreat Recorded by Iceberg Alley Sediments Open
Ice loss in the Southern Hemisphere has been greatest over the past 30 years in West Antarctica. The high sensitivity of this region to climate change has motivated geologists to examine marine sedimentary records for evidence of past epis…
