Suspension-feeding bivalve molluscs are foundation species in coastal intertidal systems.
The selective feeding capabilities of these animals can have a large influence on …

Optical particle measurements are emerging as an important technique for understanding
the ocean carbon cycle, including contributions to estimates of their downward flux, which …

Methane is an important greenhouse gas, and its atmospheric concentration has nearly
tripled since pre-industrial times. The growth rate of atmospheric methane is determined by …

As the application of nanomaterials to science and technology grows, the need to
understand any ecotoxicological effects becomes increasingly important. Recent studies on …

Autotrophic picoplankton dominate primary production over large oceanic regions but are
believed to contribute relatively little to carbon export from surface layers. Using analyses of …

We present new empirical and mechanistic models for predicting the export of organic
carbon out of the surface ocean by sinking particles. To calibrate these models, we have …

Abstract The Southern Ocean contributes substantially to the global biological carbon pump
(BCP). Salps in the Southern Ocean, in particular Salpa thompsoni, are important grazers …

The oceanic biological carbon pump (BCP) regulates the Earth carbon cycle by transporting
part of the photosynthetically fixed CO2 into the deep ocean. Suppressing this mechanism …

Carbon and nutrients are transported out of the surface ocean and sequestered at depth by
sinking particles. Sinking particle sizes span many orders of magnitude and the relative …

A considerable amount of particulate carbon produced by oceanic photosynthesis is
exported to the deep-sea by the “gravitational pump”(~ 6.8 to 7.7 Pg C/year), sequestering it …
