Prokaryotic heterotrophs play a key role in marine global carbon fluxes by way of their consumption of dissolved organic matter, respiratory CO2 production and nutrient recycling activities.
Micro-algae transform carbon dioxide (CO2) and nutrients dissolved in the ocean into organic matter and oxygen. This process, photosynthesis, uses sunlight energy. These primary producers then become an energy source for a vital link in the marine food chain, that being herbivorous zooplankton.
Ice-T is a buoy used at the Ice Camp to measure the thickness of sea ice. Anchored in the pack ice, this device provides information on atmospheric pressure, air temperature, ice drift, horizontal current, temperature, salinity at the base of the ice in addition to thermal profiles of the ice and snow. These data are as accurate (or sometimes more) than those provided by the satellite-derived mapsand are drawn up in real time.
