RECEIVER Theme 3
The transfer of matter and signals into the ocean floor
RECEIVER Theme 3 will track physical, chemical and biological parameters related to key aspects of, for example, export production and preservation of carbon in ocean-floor sediments that leave measurable signatures in the composition and properties of pelagic and benthic particles and organisms. Such signals, also known as proxies, preserve an imprint of the prevailing conditions during particle formation as well as of the processes associated with particle transformation in the water column and at the ocean floor. We will use these proxies to extract quantitative information about the oceanic carbon pump, and apply them to suitable high-resolution archives bearing the potential to reconstruct past ocean conditions on sub-decadal and shorter timescales.
