High particle export over the continental shelf of the west Antarctic Peninsula
[1] Drifting cylindrical traps and the flux proxy 234 Th indicate more than an order of magnitude higher sinking fluxes of particulate carbon and 234 Th in January 2009 than measured by a time-series conical trap used regularly on the shelf of the west Antarctic Peninsula (WAP).
