Bridging the Scale Gap from Leaf to Canopy in Biosphere-Atmosphere Gas and Particle Exchanges
The increasing dependence of European Union member countries on imported oil and gas has led to concerns about energy supply and security. At the same time the share of clean energy in Europe’s energy consumption basket is increasing due to environmental issues. About a quarter of all energy consumption in the EU is natural gas, and most EU member states import almost all of their energy resou...
[1] The impacts of the seasonal evolution of sea-ice physical properties on ice-ocean biogeochemical exchanges were investigated in landfast ice at Barrow (Alaska) from January through June 2009. Three stages of brine dynamics across the annual cycle have been identified based on brine salinity, brine volume fraction, and porous medium Rayleigh number (Ra). These are sea-ice bottom-layer convec...
