We’re collecting water and particles from the CTD/Niskin rosette, underway seawater system, and pumps that filter in situ. We use Bongo nets to collect particles […]

Simply speaking, should upwelling intensity decline let’s say by 50% […]

The last week of our cruise has begun, and the eddy hunt is aiming for an eddy in the East of Trinidad and Tobago, Eddy2. The trick with catching Eddy2 is to first estimate his dimensions by using sea level anomaly maps which give insight on surface eddies that are often overlying deeper eddies, like […]
