The ocean carbon cycle is a vital part of the global carbon cycle. It has been estimated that around a quarter of anthropogenically-produced emissions of CO2, caused from the burning of fossil fuels and land use change, have been absorbed by the ocean. On the other hand, significant advances have been made recently to expand and enhance the quality of a wide range of Remote Sensing based products capturing different aspects of the ocean carbon cycle.

BICEP will bring these developments together to increase understanding of the ocean biological pump and its processes and interactions with the Earth system.

Ocean Carbon From Space Workshop

ESA, together with Plymouth Marine Laboratory (PML) and the support from NASA, is organising the Ocean Carbon From Space Workshop, to be held virtually from 14 to 18 February 2022. This workshop is being organised as the second workshop in the CLEO (Colour and Light in the ocean from Earth Observations) Series and is a contribution to the Committee on Earth Observation Satellites (CEOS) Work Plan on the Aquatic Carbon Application area, as endorsed by the CEOS Ocean Colour Radiometry Virtual Constellation (OCR-VC) founded within the International Ocean Colour Coordinating Group (IOCCG).

Royal Society’s Summer Science 2021: How can we track and trace carbon from space?

Scientists from the BICEP project will be showing how we can use satellites to study the global carbon cycle during the Royal Society’s Summer Science 2021, which will be going totally digital from 8th to 11th July.

Dr Gemma Kulk and Dr Shubha Sathyendranath will be showcasing their research on phytoplankton – part of the European Space Agency’s ‘Biological Pump and Carbon Exchange Processes’ Read more...
