These models are based on real-time biological observations of all macro-organisms made during ground-truth surveys conducted in 2008 and 2009; the observations were made during a 10-second interval every minute along camera transects, which were approximately 1 km in length. \nFive invertebrate taxa\u2014cup corals, hydroids, short sea pens, tall sea pens, and brittle stars (which protrude out of the sediment)\u2014were selected for modeling purposes on the basis of their frequent occurrence in the Santa Barbara Channel. Presence-absence data for the selected invertebrates were fit to multiple generalized linear models using a combination of three covariates\u2014geographic location, seafloor character, and shaded-relief bathymetry\u2014as well as relevant interaction terms. Best-fit models were selected for each invertebrate based on Akaike\u2019s Information Criterion (AIC), a best-fit model being defined as the one with fewest parameters within two AIC points of the minimum score.\nSediment thickness and Depth to Transition maps show the thickness and the depth to base of uppermost Pleistocene and Holocene (post-LGM) deposits both for the Hueneme Canyon and vicinity map area and, to establish regional context, for a larger area (about 115 km of coast) that extends from the vicinity of Hueneme Canyon northwest to the Refugio Beach area. To make these maps, water bottom and depth to base of the LGM horizons were mapped from seismic-reflection profiles using Seisworks software. The difference between the two horizons was exported from Seisworks for every shot point as XY coordinates (UTM zone 11) and two-way travel time (TWT). The thickness of the post-LGM unit (Maps B, E) was determined by applying a sound velocity of 1,600 m/sec to the TWT, resulting in thicknesses as great as 65 m. The thickness points were interpolated to a preliminary continuous surface, overlaid with zero-thickness bedrock outcrops, and contoured. Data within Hueneme Canyon were excluded from the contouring because the seismic-reflection data are too sparse to adequately image the highly variable changes in sediment thickness that characterize the canyon.", "Subject": "CSMP is a cooperative program to create coastal/marine geologic and habitat base map information for all of California's State Waters.
