Atlantic Ocean
Samples of organic matter were isolated f?om seawater of the North Atlantic Ocean and Halifax Harbour by a bubble adsorptive technique. The samples thus collected, representa-tive of the organic materials important in the transport of gcochcmical species across the air-sea interface, were characteri...
