Curie depths beneath Greenland are revealed by spectral analysis of data from the World Digital Magnetic Anomaly Map 2. A thermal model of the lithosphere then provides a corresponding geothermal […]
Threats to global food security have generated the need for novel food production techniques to feed an ever-expanding population with ever-declining land resources. Hydroponic cultivation has been long recognised as […]
Aim: To predict the at-sea distribution of chinstrap penguins across the South Orkney Islands and to quantify the overlap with the Southern Ocean krill fishery. Location: South Orkney Islands, Antarctica. […]
The Southern Hemisphere westerly winds (SHW) play an important role in regulating the capacity of the Southern Ocean carbon sink. They modulate upwelling of carbon-rich deep water and, with sea […]
Nitric oxide (NO) produced in the polar middle and upper atmosphere by energetic particle precipitation depletes ozone in the mesosphere and, following vertical transport in the winter polar vortex, in […]
The life histories of cephalopods are still not well described. Stable isotopic analysis of cephalopod beaks is an effective method to study the habitat and trophic ecology of this group […]
Ice shelf break-up and disintegration events over the past 5 decades have led to speed-up, thinning, and retreat of upstream tributary glaciers and increases to rates of global sea-level rise. […]
To investigate whether impacts of reported climate change in the Antarctic marine environment have affected mesozooplankton populations, we compared the summertime abundances of four species of large calanoid copepods from […]
There is increasing interest in using higher-trophic level predators as ecosystem indicators because their performance is presumed to be linked to the overall function of the ecosystem that supports them. […]
The magnitude of observed multi‐decadal variations in the North Atlantic Oscillation (NAO) is at the upper end of the range simulated by climate models and a clear explanation for this […]
The last deglaciation represents the most recent example of natural global warming associated with large-scale climate changes. In addition to the long-term global temperature increase, the last deglaciation onset is […]
