Title:
Kailua Bay, Oahu, Hawaii Benthic Mapping Data 1999-2001 (NODC Accession 0001239)
Abstract:
Benthic mapping surveys were conducted from March 1999 to January 2001 aperiodically in support of research related to sedimentology, sea level history, and reef development. Various parameters such as substrate, coral, and coralline algae types and percent bottom coverages of each were quantified using the Linear Transect Method (LTM) or Line Intercept Technique along 30 m transects at typically -3 or -20 meters depth. Various derived parameters such as abundance and diversity were also determined.

    Substrate Mapping at 60 sites between the depths of -3 and -20m using avariation of the Linear Transect Method (LTM) or Line Intercept Technique(Stoddard and Johannes, 1978, Monetbon, 1992). Identified and measuredthe length of each substrate type that intersected a 30 m measuringtape, generally following depth contours. Sites were chosen tocharacterize dominant and transition settings inferred from the hydrographicand MSS surverys, and to randomly fill a 15" latitude-longitude grid overthe reef. Measured each change in substrate with an accuracy of0.2 m (0.6% substrate cover) and determined from replicate surveys thatprecision was reproducible at 1-3% substrate cover.
