Shipboard measurements of atmospheric

Saltzman, E. S., and Cooper, D. J., Shipboard measurements of atmospheric dimethylsulfide and hydrogen sulfide in the Caribbean and the Gulf of Mexico, J. Atmos. Chem., 7, 191-209, 1988. 

To derive the parameters r, the atmospheric transmittance, and L, the path radiance, linear regression analyses were performed on radiances from the satellite measurements, L, and radiances derived from shipboard measurements of temperature, L, versus elapsed distance, X, along selected parts of the track. These track segments were selected nearest in time to the satellite overpass and where temperature gradients were large enough to minimize the relative errors due to satellite-measured thermal noise and the lower AVHRR temperature resolution of 0.5 °C in the 8-bit data from Redwood City. 

Emissions of organohalogen (Br or I) gases (one to two carbon atoms) from the oceans can have significant effects on the oxidant chemistry of the atmosphere, and in some cases in particle formation. There is a growing database of shipboard measurements from which sea-to-air fluxes can be calculated (e. g. Chuck et al. 2005). However, in contrast to DMS, there is little understanding of how these compounds are formed, with both direct biological production and indirect photo-... 

X HE LEVELS OF INDUSTRIAL CHEMICAL WASTES BEING DUMPED into our nation s coastal waters are constantly being monitored by the National Oceanic and Atmospheric Administration (NO A A). To carry out the frequent marine monitoring programs necessary to stay abreast of this problem, it was determined in 1977 that more expedient shipboard sampling and analyses systems would have to be developed. One area of prime interest for sampling and scrutiny was the surficial seafloor sediments. To enhance rapid data collection, the ability to analytically measure samples while at sea was essential. This capability would allow areas of interest to be delineated and studied in detail before the survey vessel returned to port.
