The Antarctic has significant environmental, scientific, historic, and intrinsic values, all of which are worth protecting into the future. Nevertheless, the area is subject to an increasing level and diversity […]
Portugal has developed an active Antarctic programme over the past decade. Here, we examine Portuguese Antarctic activity using a variety of bibliometric measures, showing that Portuguese scientific output has grown […]
Ozonesonde data from four sites are analyzed in relation to 191 solar protons events (SPEs) from 1989-2016. Analysis shows ozone depletion (~10-35 km altitude) commencing following the SPEs. Seasonally-corrected ozone […]
Geothermal environments in Antarctica have profound ecological and scientific value. They are single points of heat and moisture in an icy and dry landscape, and provide habitats for diverse living […]
Emissions of nitrogen oxide (NOx = NO + NO2) from the photolysis of nitrate (NO3−) in snow affect the oxidising capacity of the lower troposphere especially in remote regions of high latitudes with little […]
The Arctic sea ice cover of 2016 was highly noteworthy, as it featured record low monthly sea ice extents at the start of the year but a summer (September) extent […]
In the marine environment, understanding the biophysical mechanisms that drive variability in larval dispersal and population connectivity is essential for estimating the potential impacts of climate change on the resilience […]
Antarctic coastal polynyas are regions of persistent open water and are thought to be key bio-physical features within the sea-ice zone. However, their use by the upper trophic levels of […]
In the present paper, we compare how the kelp gull, Larus dominicanus, utilizes various nest building materials, particularly vascular plants, bryophytes, lichens and other components, in the Fildes Peninsula area […]
Aim The aim was to investigate those factors that influenced the differentiation of high-latitude and polar marine faunas on both ecological and evolutionary time-scales. Can a focus on a greenhouse […]
