OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Map of the Arctic indicating samples collected during the CAO ARISE project
Warming of the Arctic is altering the physical environment, reducing sea ice cover and melting glaciers at unprecedented rates. The response of primary productivity by phytoplankton to enhanced light availability or increased glacial inflow will hinge on the availability of nutrient resources, especially nitrogen. Here, I will summarise our findings from the Changing Arctic Ocean programme on nutrient dynamics, cleaned from analysis of historical data sets and stable nitrogen isotopes. I will introduce new observations on the occurrence of marine nitrogen fixation in the cold Arctic Ocean and discuss implications for the future Arctic ecosystem.
