Dissolved petroleum hydrocarbons along the oil tanker route in the southern Bay of Bengal

Abstract

Concentrations of dissolved petroleum hydrocarbons during 3 cruises (Nos. 51, 66 and 68) of R V Gaveshani, along the oil tanker route, in the southern Bay of Bengal at 0, 10 and 20 m were 19.95 + or - 3.38, 16.78 + or - 2.53 and 13.45 + or - 2.17 mu g/l respectively. The values obtained during the cruise 51, along the same route differed significantly from those obtained during the cruises 66 and 68. The difference was largely attributed to the general hydrographic conditions existing during the time of sampling
