It is a glaring fact that climate, and in particular global warming and associated climate change, is having a major impact on life on Earth, and will continue to do so into the forseeable future 1, 2.
Green sulfur bacteria (GSB) (Chlorobiaceae) are primary producers that are important in global … carbon and sulfur cycling in natural environments. An almost complete genome sequence for a … single, dominant GSB species (‘C-Ace’)…
Prediction of the impact of global climate change on marine phytoplankton is fraught with uncertainties. Increasing temperature, enhanced surface stratification, alteration of ocean currents, intensification or weakening of local nutrient upwelling, stimulation of photosynthesis by elevated CO2…
Special emphasis should be placed on determining optimal sampling regimes to detect … statistically significant differences in key indicators between populations for species with high conservation … values, especially when invasive handling techniques are the only method of gathering … data.
We analyze the precursor of a Forbush decrease (FD) observed with the Global Muon Detector Network on 2006 … December 14. An intense geomagnetic storm is also recorded during this FD with the peak Kp index of 8+.
The upwelling of iron-rich Upper Circumpolar Deep Water (UCDW) is thought to be critical for primary production in the Southern Ocean, since iron has been shown to be a limiting factor in what is otherwise a high nutrient region.
Reconstructing and modeling extent and dynamics of ice sheets is crucial in … understanding and predicting the evolution of ice sheets. Key to ice sheet dynamics are ice … streams, which drain most of the ice from the ice sheet interior to the ice shelves, where most of … the ice is lost.
The Amery Ice Shelf, East Antarctica, undergoes high basal melt rates near the southern … limit of its grounding line where 80% of the ice melts within 240km of becoming afloat. A considerable … portion of this later refreezes downstream as marine ice.
Tracking features between pairs of satellite synthetic aperture radar (SAR) images using image crosscorrelation … methods is a powerful tool for defining regions of image movement such as ice flow of Antarctic … glaciers. Unlike optical images…
Determining the mass balance of the Greenland and Antarctic ice sheets (GIS and AIS) has long … been a major challenge for polar science. But until recent advances in measurement technology…
It has recently been shown that sea ice (via frost flowers) is an important source of sea … salt to coastal Antarctica. This has been used to suggest that the sea salt record from … ice cores may reflect a proxy for sea ice extent around Antarctica. In this study…
The Antarctic-Arctic Radiation-belt (Dynamic) Deposition-VLF Atmospheric Research Konsortium … (AARDDVARK) provides a network of continuous long-range observations of the lower ionosphere in the … polar regions.
Techniques are presented for generating thermal infrared and … visible composite images from cloud-free portions of MODIS … (MODerate resolution Imaging Spectroradiometer) images … closely spaced in time, with a focus on studies of landfast sea … ice along the East Antarctic coast.
