Abstract:
Sinking organic particles were collected from the Porcupine Abyssal Plain in 2013. Collection was done using a marine snow catcher (MSC), which is essentially a large (95 L) settling column. The marine snow catcher is deployed to one depth, the water trapped inside and then brought to the surface and left to stand on deck for 2 hours during which time the particles settle down (or up) the MSC depending on their settling rate. The particles are then collected and due to position of collection from the snow catcher are determined as fast or slow sinking particles. Some fluxes are negative as they were positively buoyant and not sinking.

Comment:
Calculated carbon fluxes using the marine snow catcher at the PAP site in June 2013, cruise JC087. Fluxes are separated as either fast or slow sinking particulate organic carbon. Sinking rates were measured using method established by Ploug and Jørgensen (1999) and developed by Morten Iversen.
