Title: "Microbially-Driven Shifts in Marine Nutrient Cycling in Response to Ocean Deoxygenation and Climate Change"

Speaker: Julia Huggins

Event Date: Tuesday, 5 December 2023, 12:00 - 13:00 h EST

"The oceans are currently losing dissolved oxygen (O2) as a result of climate change and human activity, which may have dramatic effects on biodiversity and global climate feedbacks. As O2 is depleted to near-anoxia in pelagic marine environments, microorganisms shift from aerobic respiration to anaerobic nitrogen-based metabolisms. Most conceptual and numerical models assume this shift will lead to nitrogen loss, but it can also lead to nitrogen retention depending on which microbial metabolism(s) engage. The controls regulating the relative activity and variability of these metabolisms remain uncertain, however, and this confounds our efforts to predict how the marine nitrogen cycle responds to deoxygenation and impacts other marine biogeochemical cycles. I conduct experiments with live marine microbial communities to measure how different nitrogen-based microbial metabolisms are regulated in the transition from oxic to anoxic conditions. I use a combination of stable nitrogen isotopes (15N) and bioinformatics technologies to increase our knowledge of how competing microbial metabolisms are regulated under variable environmental conditions and unstable resource availability. My work has implications for our biogeochemical models that predict ocean deoxygenation and related climate feedbacks."

Title: "Sailing for oxygen - how citizen science can help understand ocean deoxygenation"

Event Date: Thursday, 7 December 2023, 13:00 - 14:00 h

"On Thursday 7 December 2023, EMB will host its 35th Third Thursday Science Webinar featuring Toste Tanhua who will speak about "Sailing for oxygen - how citizen science can help understand ocean deoxygenation".

This topic is linked to the science within the EMB Future Science Brief No. 10 'Ocean oxygen: the role of the Ocean in the oxygen we breathe and the threat of deoxygenation'.

Toste Tanhua is a Senior Scientist at GEOMAR (Germany) and chemical oceanographer. His work focuses on Ocean ventilation by observing transient tracers and conducting deliberate tracer release experiments to understand ventilation and mixing in the Ocean. He also works on understanding the dynamics of Ocean carbon, nutrients and oxygen. In addition, he is co-chairing the steering committee of the Global Ocean Observing System (GOOS) and coordinating the EU funded project EuroSea, that aims at improving the ocean observing and forecasting system."

"On behalf of the 'Global Ocean Oxygen Database and Atlas’ steering committee we are very happy to share a short survey (10 questions, less than 10 minutes).

Ocean oxygen data are a critical part to understand our ocean today and in the future. However, currently there is no common entry point to obtain ocean oxygen data of known quality from the open and coastal ocean, measured from Eulerian and Lagrangian platforms. Within the Ocean Decade Programme 'Global Ocean Oxygen Decade' (GOOD) an effort called 'Global Ocean Oxygen Database and ATlas' (GO2DAT) is trying to change this.

This survey is the first step to implement GO2DAT. We count on your cooperation to identify who, where and how ocean oxygen is measured, what type of quality checks and flags are applied. This information will be indispensable to have ocean oxygen data complying with the FAIR and CARE principles.

Please submit your response by 30 June 2023."
