Krill faecal pellets drive hidden pulses of particulate organic carbon in the marginal ice zone
Abstract: The biological carbon pump drives a flux of particulate organic carbon (POC) through ... the ocean and affects atmospheric levels of carbon dioxide. Short term, episodic flux events are hard ... estimates. We model the potential hidden flux of POC originating from Antarctic krill, whose swarming ... behaviour could result in a major conduit of carbon to depth through their rapid exploitation of ...
