Abstract : Strandings of oil and tar on Galveston Island beaches were assessed for 1 year. Most materials collected were tars or tar-like residues that appeared to be highly weathered. There did not appear to be a consistent relationship between oil accumulation and wind speed and direction. Efforts to correlate oil deposition with shipping traffic were unsuccessful. Representative oil tar samples were analyzed periodically by (a) gas chromatography for hydrocarbons, (b) atomic absorption spectrophotometry for nickel, vanadium, chromium and cobalt, (c) carbon 12/13 ratios, and (d) X-ray diffraction analysis for minerals. Most of the samples analyzed appear to be the result of man's activities. (Modified author abstract)
