Applied Marine Biogeochemistry Groupat the Institute for Marine and Antarctic Studies
Marine biogeochemistry investigates element cycles in the ocean. We study the effects of deliberate changes in these element cycles, for example in the carbon cycle
We do field and laboratory research to improve our understanding of how the ocean works
Currently, we focus on the assessment of ocean alkalinity enhancement (OAE) as a strategy for marine carbon dioxide removal (mCDR)
OAE field study 2024
Follow the 2024 field programme from scouting and plot setup to sampling and recovery.
Day 1
Day (1) – scouting the field site and initial testing of equipment
Our main goal on day 1 (17.9.2024) was to find the best study site within the area for which we have a...
Day 2
Day (2) – Learning about how to do oae research in sediments
Our main goal on day 2 (9.10.2024) was to learn how OAE minerals can be applied underwater in a way that...
Day 3
Day (3) – Setting up the plots for the field study
Our main goal on day 3 (22.10.2024) was to set up the 12 plots on which the study will be conducted. This...
Days 4-7
Day 4 to Day 7 – Adding minerals to the seafloor and taking samples from the plots
Our main goal on days 4-7 (1.11.2024, 46.11.2024) was to get the alkaline minerals on ~1.5 m 2 plots on the...
Day 8
Day (8) – 10 days after deployment
Ten days after deployment, we sampled water in the 12 plots and obtained small sediment cores in the tracer...
Days 9-10
Day (9) and (10) – 31 days after deployment
A month after deployment, likely marking the final days of sampling for this experiment, we spent two...
Days 11-12
Day (11) and (12) – 77 days after deployment
The last two days at the field site were a whirlwind of sediment coring, carbonate chemistry sampling,...
