Benthic diatoms modify riverine silicon export to a marine zone in a hypertidal estuarine environment
Read more of: Benthic diatoms modify riverine silicon export to a marine zone in a hypertidal estuarine environmentRiverine dissolved silicon (DSi) and biogenic silica (BSi) are modulated along the estuarine gradient by several biotic and abiotic processes governed by physical forcings. An important area controlling silicon transport […]

New evidence for preservation of contemporary marine organic carbon by iron in Arctic shelf sediments
Read more of: New evidence for preservation of contemporary marine organic carbon by iron in Arctic shelf sedimentsThe protection of organic carbon through association with iron minerals (FeR) is an important factor in its stabilisation, long-term storage, and burial efficiency in marine sediments. However, large uncertainties still […]

Survivors and colonizers: Contrasting biogeographic histories reconciled in the Antarctic freshwater copepod Boeckella poppei
Read more of: Survivors and colonizers: Contrasting biogeographic histories reconciled in the Antarctic freshwater copepod Boeckella poppeiTwo main hypotheses have been proposed to explain the contemporary distribution of Antarctic terrestrial biota. We assess whether the current distribution of maritime Antarctic populations of the freshwater copepod Boeckella […]

Last Interglacial Arctic sea ice as simulated by the latest generation of climate models
Read more of: Last Interglacial Arctic sea ice as simulated by the latest generation of climate modelsThe 16 models that simulated the Last Interglacial climate as part of the CMIP6/PMIP4 exercise consistently produce a smaller Arctic summer sea-ice area compared to the pre-industrial period, but their […]

Reconstructing Antarctic sea ice from 130,000 years ago
Read more of: Reconstructing Antarctic sea ice from 130,000 years agoPast warm periods serve as an analog for the impacts of future warming. Reconstructions of Antarctic sea ice from 130,000 years ago show a reduction in sea-ice extent relative to […]

Snow petrel stomach-oil deposits as a new biological archive of Antarctic sea ice
Read more of: Snow petrel stomach-oil deposits as a new biological archive of Antarctic sea iceWhere snow petrels forage is predominantly a function of sea ice. They spit stomach oil in defence, and accumulated deposits at nesting sites are providing new opportunities to reconstruct their […]

Antarctic Seabed Assemblages in an Ice-Shelf-Adjacent Polynya, Western Weddell Sea
Read more of: Antarctic Seabed Assemblages in an Ice-Shelf-Adjacent Polynya, Western Weddell SeaIce shelves cover ~1.6 million km2 of the Antarctic continental shelf and are sensitive indicators of climate change. With ice-shelf retreat, aphotic marine environments transform into new open-water spaces of […]

Palaeozoic – Early Mesozoic geological history of the Antarctic Peninsula and correlations with Patagonia: Kinematic reconstructions of the proto-Pacific margin of Gondwana
Read more of: Palaeozoic – Early Mesozoic geological history of the Antarctic Peninsula and correlations with Patagonia: Kinematic reconstructions of the proto-Pacific margin of GondwanaThe Antarctic Peninsula preserves geological evidence of a long-lived continental margin with intrusive, volcaniclastic and accretionary complexes indicating a convergent margin setting from at least the Cambrian to the Cenozoic.

Antarctic Bedmap data: Findable, Accessible, Interoperable, and Reusable (FAIR) sharing of 60 years of ice bed, surface, and thickness data
Read more of: Antarctic Bedmap data: Findable, Accessible, Interoperable, and Reusable (FAIR) sharing of 60 years of ice bed, surface, and thickness dataOne of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are crucial for modelling ice flow and hence for […]

Horizon scanning for potential invasive non-native species across the United Kingdom Overseas Territories
Read more of: Horizon scanning for potential invasive non-native species across the United Kingdom Overseas TerritoriesInvasive non-native species (INNS) are recognized as a major threat to island biodiversity, ecosystems, and economies globally. Preventing high-risk INNS from being introduced is the most cost-effective way to avoid […]
