| Title: | Benthic faunal sampling adjacent to the Barbers Point ocean outfall, Oahu, Hawaii, 1986-2010 (NODC Accession 9900098) |
| Abstract: | Benthic fauna in the vicinity of the Barbers Point (Honouliuli) ocean outfall were sampled from 1986-2010. To assess the environmental quality, sediment grain size and sediment chemistry were measured. To identify the fauna, mollusk species and non-mollusk species sitings were tabulated. Stations were located both within and on the boundary of the zone of initial dilution (ZID) and at distances of 1.2 to 2 km from the ZID boundary. In summary, the response patterns of benthic fauna near the Barbers Point ocean outfall showed little or no indication of a strong influence by the diffuser effluent. Seven stations previously established along the approximate diffuser isobath (61 m) were surveyed. In 1990 survey station names were changed from those used in the 1986 survey (Nelson et al. 1987). Survey stations (1986 station names are in parenthesis) and their locations are as follows: Station HB1 (A) Approximately 3.5 km east of the zone of initial dilution (ZID) boundary to evaluate effects far-field and beyond the ZID Station HB2 (B) On the northeast ZID boundary Station HB3 (C) On the southeast ZID boundary Station HB4 (D) On the southwest ZID boundary Station HZ (Z) Within the ZID to evaluate diffuser effects Station HB6 (E) Approximately 0.5 km southwest of the ZID boundary as a near-field reference station Station HB7 (F) Approximately 3.5 km southwest of the ZID boundary as a far-field reference station SAMPLING PERIODS: September 1986 February 1990 July 1991 February 1992 June 1993 June 1994 January 1995 January 1996 January-February 1997 January 1998 April 1999 February-March 2000 January 2001 January 2002 January 2003 June 2004 February 2005 February 2006 July 2007 June 2008 March 2009 June 2010 missing years: 1987-89 METHODOLOGY: 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. Five van Veen grabs were taken at each station. A subsample 7.6 cm in diameter by 5 cm deep was taken from each grab sample for infaunal analysis and a subsample 4.8 cm in diameter by 5 cm deep for mollusk analysis. Subsampling was necessary because the epifauna and infauna in the area are known to be both small and abundant and processing of the entire sample would be impractical. Replicated grab samples at each station, rather than replicated subsamples from one grab sample, were used to provide information on intrastation variability. All six nonmollusk subcores were processed on a 0.5-mm screen. 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). |
