🌊 Oxygen Minimum Zone Chlorophyll Maximums 🌊

🚀🛰️🦠When the upper boundary of an OMZ approaches the euphotic depth in stratified regions, an OMZ-chlorophyll maximum can form at depths of 68-160m in extremely low-light and low oxygen.🚀🛰️🦠

“We survive on collecting and selling the seafood, but we are also protecting them. We show how humans and nature can coexist.”

#Freediving for food is the most selective fishing method there is. It's challenging & time-consuming, but rewarding.
Amazing story from South Korean freediving culture🌊🦑

The RAPID-MOCHA-WBTS time series of the Atlantic overturning circulation will soon reach 20 years (started in 2004) thanks to the many people (crew, officers, students and researchers) who have participated in the research expeditions that regularly maintain the observing array.
The next RAPID 26N AMOC expedition will sail from Fort Lauderdale on the 11th December 2024. Updates to follow.
