‘The decay of organic matter in the oceans, now and in the future

Date: 
Thursday 2 August 2018 - 14:00 to 15:00
Location: 
NOC Southampton - Node Room (074/02) (Waterfront Campus).

Sinking organic particles transfer large amounts of carbon to the deep ocean and sediments where it can be stored on long timescales, which helps to regulate atmospheric carbon dioxide levels. As it sinks, small organisms such as zooplankton or microbes degrade the carbon and convert it back into its original inorganic form, reducing the amount of carbon that can be sequestered/stored. Currently, we know a lot about the surface ocean, and also what we learn from samples from sediment traps deep in the ocean, but not what happens in-between.

 

In this talk I will show what happens during the decay and remineralisation of organic matter and also how we can predict how it may change with future warming.
