   Date: unknown (process 1 of 1)

   The sampling methodology used in this study generally followed the recommendations of Swartz (1978) and US EPA guidelines (EPA 1987a, 1987b), hereafter refered to as EPA procedures.

   A modified 0.16-m2 van Veen grab sampler deployed from a stern-mounted A-frame on the research vessel Noi I Kai was used to obtain bottom samples at all seven stations. Penetration of the sampler was adequate for all replicates. The minimum penetration depth for all grabs was 8 cm and the maximum was 15 cm.

   Samples for geochemical analyses (total organic carbon (TOC), oxidation-reduction potential (ORP), sediment oil and grease (O&G), total Kjeldahl nitrogen (TKN), and grain size) were obtained from the grabs from which the biological subcores were taken. Each replicate van Veen grab contained more than enough sediment for both purposes (methods HI0020117). Three subsamples 7.6 cm in diameter by 5 cm deep (one from each of three differnt grab samples) were taken from all stations. The top 2 cm of sediment of each subsample were used for geochemical analysis. Samples for TOC and sediment O&G analysis were put in screw-cap jars, placed on ice, and taken to the laboratory for analysis. Sediment analyses of sediment grain size, ORP, TKN, and O&G followed EPA procedures. Analysis of TOC was carried out by PACE, Inc. Laboratory (Southern California).
