Past projects:
GOCART will use AUVs to investigate seasonal and high frequency variability in organic carbon fluxes and remineralisation. Glider deployments will be used to establish the characteristics and significance of temporal variability in organic carbon flux and remineralisation depth. This will give new insights into the factors driving variability in remineralisation depth, ultimately leading to development of a new model parameterisation incorporating temporal variability.
COMICS (Controls over Ocean Mesopelagic Interior Carbon Storage) aims to quantify the flow of carbon in the ocean’s ‘twilight’ zone in order to more accurately model global climate change. We have had two expeditions to two fascinating sites: The Benguela Upwelling off the coast of Namibia and the Southern Ocean around South Georgia. By studying these two contrasting environments, we can better understand what drives ocean carbon storage.
CUSTARD (Carbon Uptake and Seasonal Traits in Antarctic Remineralisation Depth)will examine how seasonal changes in food availability for phytoplankton at a key junction of the global ocean circulation influences how long carbon is trapped in the ocean rather than escape to the atmosphere as carbon dioxide.
