Test WG summary module OC3


OC3 was active from 2014 to 2019 and focussed on reconstructing ocean circulation and carbon cycling over the last 20,000 years by synthesizing carbon isotopes (d13C) measured on shells of benthic foraminifera from sediments of all ocean basins. More than 90 international scientists were involved.


- To synthesize core-top data and compare to water-column measurements for a new global calibration (completed).
- To synthesize down-core data and create an easily updatable database with consistent age models and uncertainty estimates.
- To analyze the down-core database and compare it with model results in order to better understand and quantify changes in ocean circulation and carbon cycling during the past 20,000 years.
