Spatial distribution of transparent exopolymer particles in the Bransfield
Transparent exopolymer particles (TEP) are recognized to play an important role in the flux of exported carbon to the deep ocean. However, there is little information on how TEP standing stocks are affected by different hydrographic conditions and other relevant ecological factors in situ. This lack...

Transparent exopolymer particles (TEP) are recognized to play an important role in the flux of exported carbon to the deep ocean.
