Perspectives on marine zooplankton lipids 1
We developed new perspectives to identify important questions and to propose approaches for future research on marine food web lipids. They were related to (i) structure and function of lipids, (ii) lipid changes during critical life phases, (iii) trophic marker lipids, and (iv) potential impact of climate change. The first addresses the role of lipids in membranes, storage lipids, and buoyancy...
متن کاملAn Unaccounted Fraction of Marine Biogenic CaCO3 Particles
Biogenic production and sedimentation of calcium carbonate in the ocean, referred to as the carbonate pump, has profound implications for the ocean carbon cycle, and relate both to global climate, ocean acidification and the geological past. In marine pelagic environments coccolithophores, foraminifera and pteropods have been considered the main calcifying organisms. Here, we document the prese...
متن کاملThe production of volatile iodocarbons by biogenic marine aggregates
We present the first reported measurements of volatile iodocarbon production by biogenic marine aggregates. Iodomethane (CH3I), iodoethane (C2H5I), 2iodopropane (CH3CHICH3), and 1-iodopropane (CH3CH2CH2I) concentrations were determined in incubations of aggregates formed by concentrating the .53 mm fraction of the plankton during a field campaign in the Celtic Sea. All four iodocarbons increase...

متن کاملSub-Antarctic marine aerosol: dominant contributions from biogenic sources
Biogenic influences on the composition and characteristics of aerosol were investigated on Bird Island (5400 S, 3803 W) in the South Atlantic during November and December 2010. This remote marine environment is characterised by large seabird and seal colonies. The chemical composition of the submicron particles, measured by an aerosol mass spectrometer (AMS), was 21 % non-sea-salt sulfate, 2 % ...
