- #exoCeanadvent Day 8: Meet Katoo Declerk's Erasmus+ work. During her internship Katoo is investigating recently dead foraminifera (handily available in our lab!) Forams typically sink to the ocean floor soon after death, but partial or total dissolution can occur before getting there.Dec 8, 2025 15:23
- To quantify this initial dissolution action, Katoo is carefully placing recently deceased individuals inside tiny capillary sized tubes, and measuring pH and oxygen gradients near the carbonate shell over several days (roughly sinking time).
- Once finished, these measurements will be combined with CT scans, and modelling to work out exactly what is happening in these first stages of sediment formation, or indeed alkalinity recycling in the water column. Stay tuned for results later in Katoo's project!
