New paper out in Global Biogeochemical Cycles! 🌍🌊
We used isotopic tracers to show how sediments shape nitrous oxide (N₂O) production in the Southern Benguela Upwelling System, linking oxygen, nutrient cycling, and climate.

Meet the WAM Biogeochemical Modelling Team 🌍

Using high-resolution models and ocean data, this team explores oxygen dynamics, nutrient cycling, and productivity along the West African margin to understand drivers of hypoxia and ecosystem change.

#TeamWAM #OceanScience #ClimateResearch

Say hello to the 'Ocean Observations: Nitrogen, Carbon, and Oxygen' Team! 🌊 They’re measuring nitrogen, carbon, and oxygen at sea to uncover how these cycles shape productivity, nutrient supply, and oxygen variability along the West African margin.

Meet the WAM Project Support Team! 🔧
This dedicated group ensures the smooth operation of the WAM project, from managing finances and logistics to maintaining lab equipment and supporting sample analysis.

Geology rocks. During #salasygomez expedition, ROV pilots collected this footage on the western flank of an unnamed seamount. It shows how vital seamounts & rocky surfaces are in the deep Ocean, providing a habitat for animals to cling to in water column & access to nutrients.

Say hello to the Atmosphere-Ocean Interactions Team!
They’re unravelling how ocean-atmosphere exchanges shape marine chemistry and climate, from nitrogen isotope work to aerosol impacts. Another key part of the WAM puzzle!

Meet the WAM Ecosystem Modelling Team!
They’re using ecosystem modelling tools to explore how changing oxygen levels affect marine ecosystems in the Benguela Current.

Say hello to the WAM Trace Metals Team!
They’re investigating how metals move through aquatic systems and affect productivity in low-oxygen waters, from the lower Orange River to the Benguela Upwelling.

Meet the Ocean Robotics Team!
Using gliders packed with sensors, the team is studying how physical and biogeochemical processes control oxygen variability along the West African Margin. A key step in understanding low-oxygen zones and their climate impacts.

It’s #WorldOceansDay!🌊 The theme this year? Catalysing Action for Our Ocean & Climate. At WAM, we’re tackling a quiet crisis: ocean deoxygenation. Less oxygen = more risk for marine life + food security. We’re building models & collecting data to turn science into action. #WAMProject #OceanClimate

Polymetallic nodules can generate oxygen in total darkness, no sunlight needed. As WAM explores oxygen dynamics along the West African margin, findings like this show how much we still don’t know about deep-sea systems.

From 9–16 April, WAM team members joined a routine survey aboard RV Mirabilis along the Namibian coast. The cruise coincided with a major marine die-off. Early results point to extreme anoxic conditions, key to WAM’s focus on oxygen-deficient zones. 📷: Sina Wallschuss

Mass die-off of octopuses, lobsters & fish on the Namibian coast signals growing ocean stress. Hypoxia, possibly from stratification or sulphur eruptions, may be to blame. WAM scientists were on a cruise collecting data during the event. More updates soon.
