24 July, 2018 by Geraint Tarling, Sally Thorpe, Sophie Fielding

Diel vertical migration (DVM) behaviour in swarms of Antarctic krill (Euphausia superba Dana, 1850) is notoriously variable, with swarms being found at a range of depths and in different shapes,…

Age-related variation in non-breeding foraging behaviour and carry-over effects on fitness in an extremely long-lived bird

1 July, 2018 by Richard Phillips, Thomas Clay, Thomas Clay

1.Senescence has been widely documented in wild vertebrate populations, yet the proximate drivers of age‐related declines in breeding success, including allocation trade‐offs and links with foraging performance, are poorly understood.…

A horizontal ice core from Taylor Glacier, its implications for Antarctic climate history, and an improved Taylor Dome ice core time scale

1 July, 2018 by Robert Mulvaney

Molecular data suggest long-term in situ Antarctic persistence within Antarctica’s most speciose plant genus, Schistidium

5 June, 2018 by Elisabeth Biersma, Jennifer Jackson, Katrin Linse, Peter Convey

From glacial reconstructions it is clear that Antarctic terrestrial life must have been extremely limited throughout Quaternary glacial periods. In contrast, recent biological studies provide clear evidence for long-term in…

On the ecological relevance of landscape mapping and its application in the spatial planning of very large marine protected areas

1 June, 2018 by Huw Griffiths, Katrin Linse, Oliver Hogg

In recent years very large marine protected areas (VLMPAs) have become the dominant form of spatial protection in the marine environment. Whilst seen as a holistic and geopolitically achievable approach…

A “shallow bathtub ring” of local sedimentary iron input maintains the Palmer Deep biological hotspot on the West Antarctic Peninsula shelf

1 June, 2018 by Michael Meredith

Palmer Deep (PD) is one of several regional hotspots of biological productivity along the inner shelf of the West Antarctic Peninsula. The proximity of hotspots to shelf-crossing deep troughs has…

Impact of sea-ice melt on dimethyl sulphide (sulfoniopropionate) inventories in surface waters of Marguerite Bay, West-Antarctic Peninsula.

1 June, 2018 by Hugh Venables, Michael Meredith

The Southern Ocean is a hotspot of the climate-relevant organic sulfur compound dimethyl sulfide (DMS). Spatial and temporal variability in DMS concentration is higher than in any other oceanic region,…

Long-lasting geomagnetically induced currents and harmonic distortion observed in New Zealand during the 07-08 September 2017 Disturbed Period

1 June, 2018 by Mark Clilverd

Several periods of Geomagnetically Induced Currents (GIC) were detected in the Halfway Bush substation in Dunedin, South Island, New Zealand, as a result of intense geomagnetic storm activity during 06…

Summer drivers of atmospheric variability affecting ice shelf thinning in the Amundsen Sea Embayment, West Antarctica

30 May, 2018 by Andrew Orr, Scott Hosking, John Turner, Pranab Deb

Satellite data and a 35‐year hindcast of the Amundsen Sea Embayment summer climate using the WRF model are used to understand how regional and large‐scale atmospheric variability affects thinning of…

Representing grounding line migration in synchronous coupling between a marine ice sheet model and a z -coordinate ocean model

1 May, 2018 by Adrian Jenkins, James Jordan, Paul Holland, Robert Arthern

Synchronous coupling is developed between an ice sheet model and a z-coordinate ocean model (the MITgcm). A previously-developed scheme to allow continuous vertical movement of the ice-ocean interface of a…

High intake rates of microplastics in a Western Atlantic predatory fish, and insights of a direct fishery effect

1 May, 2018 by Simon Morley

Microplastic contamination was investigated in the gut contents of an economically important estuarine top predator, Cynoscion acoupa, according to spatiotemporal and ontogenetic use of a tropical estuary. Microplastic contamination was…

Quantifying Debris Thickness of Debris-Covered Glaciers in the Everest Region of Nepal Through Inversion of a Subdebris Melt Model

1 May, 2018 by Michael McCarthy, Michael McCarthy

Debris‐covered glaciers are ubiquitous in the Himalaya, and supraglacial debris significantly alters how glaciers respond to climate forcing. Estimating debris thickness at the glacier scale, however, remains a challenge. This…
