Quantifying CO2 uptake and biological productivity in the southern hemisphere oceans using atmospheric observations ...
In this thesis, the use of atmospheric observations for quantifying the uptake of `CO_2` and biological production in the Southern Ocean is explored. For both these processes, ocean observations appear insufficient to accurately quantify their magnitude and variability. It has been proposed that atm...
