The impact that biogenic emissions have on aerosol-cloud interactions across the Southern Ocean is poorly quantified. Here we use satellite and ship observations during austral summer to study these interactions.
Manganese (Mn) is an essential element involved in photosynthesis, yet its concentrations in Southern Ocean open waters are very low, arising from biological uptake and limited external inputs. At southern latitudes…
Snow on Antarctic sea ice plays a complex and highly variable role in air-sea-ice interaction processes and the Earth's climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics:
Despite widespread iron (Fe) limitation in the Southern Ocean, intense phytoplankton blooms are observed around productive coastal regions such as the Mertz Polynya (off George V Land and Adelie Land, East Antarctica; 140–155°E). Sources of Fe across coastal East Antarctica vary…
The availability of iron (Fe) to marine microbial communities is enhanced through complexation by ligands. In Fe limited environments, measuring the distribution and identifying the likely sources of ligands is therefore central to understanding the drivers of marine productivity.
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission … to promote international cooperation among research groups investigating the mesopause … region (80-100 km) with the goal of early identification of changing climate signals.
Space weather forecasting is a very important tool for the space situational awareness to the space objects, the space environment and related threats and risks for manned and non-manned spacecrafts. The global network of ground based multi-directional detectors (GMDN)…
We use complementary observations from the prototype Global Muon Detector Network (GMDN) and the Advanced Composition Explorer satellite to identify precursors of geomagnetic storm events. The GMDN was completed in March 2006 with the installation of the Kuwait detector…
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission to promote international cooperation among research groups investigating the mesopause region (80-100 km) with the goal of early identification of changing climate signals.
Satellite remote sensing observations of three break-up events in 2008 for the Wilkins Ice Shelf (28 February … to 6 March, 27 May to 31 May, and 28 June to mid-July) provide unprecedented detail of ice shelf calving … during rapid break-up.
