As part of the 14th International Conference on Paleoceanography in 2022 ( we are organizing a one day post-conference workshop on 3 September.

Title of workshop: A synthesis of Cenozoic paleoceanographic proxies for seawater oxygenation. 

Location: Bergen University, Bergen, Norway. The meeting will be held as a hybrid event, meaning there will be the possibility to participate online or in-person.  

Number of participants: 30.

There will be some funding to support ECR participants and/or participants from low- to middle income countries, generously provided by PAGES.

Workshop aim: to review Cenozoic paleoceanographic proxies used for assessing seawater oxygen concentrations (qualitative and quantitative), with in-depth discussion of potential restrictions, issues and specific regional applications. Furthermore we will host a discussion about convening a PAGES working group on Past Ocean Deoxygenation. 

Background: Ocean deoxygenation is a pressing issue, with climate models predicting that the recently discovered declining trend will continue well into the future. In order to extend seawater oxygen records, and to understand longer-term (> centennial and millennial time-scales), paleoceanographers are actively developing and refining proxy methods to assess seawater oxygenation. Over the last decade various new proxy methods have been proposed that complement existing ones, but there have also been advances / refining of traditionally used proxies. During this 1 day hybrid-workshop we will bring together researchers who have been leading the development and application of both traditional and new proxy methods using marine sedimentary archives. This includes proxy methods to assess bottom water oxygenation: sedimentology, sediment redox trace elements, corals, benthic foraminifera assemblages, morphology and trace elements; and methods to assess pelagic subsurface water oxygenation: planktonic foraminifera assemblage, nitrogen isotopes, trace elements and morphology.  

The meeting will initiate and/or develop the writing of a planned synthesis paper through a series of break-out sessions and will also involve time to discuss key global perspectives and the potential coordination for an application for a PAGES working group.

Registration closes May 1st 2022.
