Air exposure of coral is a significant source of dimethylsulfide (DMS) to the atmosphere
Corals are prolific producers of dimethylsulfoniopropionate (DMSP). High atmospheric concentrations of the DMSP breakdown product dimethylsulfide (DMS) have been linked to coral reefs during low tides. DMS is a potentially key sulfur source to the tropical atmosphere, but DMS emission from corals during tidal exposure is not well quantified. Here we show that gas phase DMS concentrations (DMSga...
متن کاملProduction and consumption of dimethylsulfide (DMS) in North Atlantic waters
Production and consumption of dimethylsulfide (DMS) were studied in surface waters of the northwest Atlantic between latitude 32° and 45° N during May 1998. The kinetics of DMS production by the whole planktonic community were studied in short-term (3 h) experiments using additions of dissolved dimethylsulfoniopropionate (DMSPd) (0 to 3000 nM). Measurements of DMS production and DMSPd consumpti...

متن کاملThe three steps of the carbonate biogenic dissolution process by microborers in coral reefs (New Caledonia).
Biogenic dissolution of carbonates by microborers is one of the main destructive forces in coral reefs and is predicted to be enhanced by eutrophication and ocean acidification by 2100. The chlorophyte Ostreobium sp., the main agent of this process, has been reported to be one of the most responsive of all microboring species to those environmental factors. However, very little is known about i...
متن کاملStimulation of gross dimethylsulfide (DMS) production by solar radiation
[1] Oceanic gross DMS production (GP) exerts a fundamental control on the concentration and the sea‐air flux of this climatically‐active trace gas. However, it is a poorly constrained process, owing to the complexity of the microbial food web processes involved and their interplay with physical forcing, particularly with solar radiation. The “inhibitor method”, using dimethyldisulfide (DMDS) or...
