Using vessel-based LiDAR to quantify coastal erosion during El Nin~o and inter-El Nin~o periods in Monterey, CA. |
|
Vessel-based LiDAR was employed to measure shoreline geomorphology, and quantify the rates of erosion and spatial distribution of coastal retreat around Monterey Bay, California during the 2008–2009 normal (non-El Nin~o) winter and 2009–2010 El Nin~o winter. These data were compared with pre- and post- El Nin~o airborne topographic LiDAR data from 1997 and 1998 to assess shoreline change since 1997. |

Rippled scour depressions add ecologically significant heterogeneity to soft sediment habitats on the continental shelf. |
|
Comprehensive high-resolution seafloor mapping of California's state waters have revealed rippled scour depressions (RSD) to be one of the most abundant and widespread habitats of the inner continental shelf. These sharply delineated elongate features range in size from 100's to 1000's of m² in aerial extent and are characterized by 30 to 50 cm deep depressions of coarser sediments and longer period bedforms than found on the surrounding seabed. Although RSDs have been identified on many of the world's continental margins, previous studies focused on their geomorphology and dynamics, leaving the ecological influence and associated biological communities of RSDs unexplored. Here we test the hypothesis that there are ecologically important differences in the distribution and abundance of benthic fish and invertebrate groups inside and outside RSDs. . [PDF] |

A Predictive Habitat Model for Endangered White Abalone Restoration Planning in Southern California. |
|
The aim of this study was to develop a predictive white abalone habitat model from high-resolution multibeam bathymetry data by analyzing relationships between occurrence patterns and geomorphology of the seafloor at Tanner Bank in California, where the presence white abalone has been well documented using ROV video transect surveys. |

Detection of Geomorphic Change in the Monterey Submarine Canyon Head. |
|
Although past research showed expansion in the canyon, it is still not understood if this is a long term pattern or part of an oscillation pattern. The results of the raster subtraction indicate that the canyon is in a state of erosion with an annual net loss of 240,000 m³ of substrate between fall 2005 and fall 2008. The rate of erosion has decreased since Smith et al. 2007 found the annual net rate of erosion to be 400,000 m³ between fall 2002 and winter 2005. Both techniques of tracing the canyon lip statistically gave the same results. The study failed to reject the null hypothesis of no change occurring in the canyon lip. Comparison between current study and fall 2002 also failed to show significant change. These results indicate that in the scope of this time series study of the canyon lip is not moving monotonically toward Moss Landing Harbor but rather in a pattern of oscillation.[PDF] |

Using sidescan sonar in determining the spatial and temporal distribution of the market squid (Loligo opalescens) spawning event, Monterey Bay, California. |
|
The squid Loligo opalescens (market squid) has become the most important fishery in California in both commercial landings and their monetary value. Market squid are also important to other commercially valuable species as food as well as protected marine mammals and birds. Five surveys were conducted in southern Monterey Bay to determine if sidescan sonar could be used to accurately assess egg abundance and therefore predict squid landings. The reliability of sidescan sonar in predicting egg abundance was found to be good as long as mean individual egg patch area was above the threshold of 0.25m2 and the data was of good quality and easily interpreted. Market squid was found to not have a preference for depth of egg laying activities beyond their normal limits. It was also found that sidescan sonar can predict landings (r2=0.980) with some certainty. [PDF] |

Modeling rockfish abundance and distribution at Cordell Bank National Marine Sanctuary, California |
|
The general hypothesis is that because rockfish are not randomly distributed across habitats, it should be possible to model and predict their distribution and abundance based on habitat maps and biological data. The purpose of this study was to test this hypothesis using autoclassification of multibeam bathymetry and acoustic backscatter data along with submersible video data of the seafloor and rockfish from Cordell Bank National Marine Sanctuary to determine how well rockfish distribution of three species of rockfish could be modeled based on seafloor habitat parameters.

Past studies have quantified the widening, deepening and rate of change in the Elkhorn Slough main channel and tributaries. This study determined whether the Parson Slough tributary is changing as rapidly, and in the same direction, as the main channel. . [PDF] |

A bathymetric analysis of equilibrium potential within Elkhorn Slough, California |
|
Critical areas affected by tidal scour have been identified as a result of multi-year mapping efforts. This project had three goals: 1)creating a bathymetric model of the slough environment, accomplished by the use of multibeam sonar, single beam sonar and terrestrial LIDAR, 2)quantifying rates and spatial distribution of erosion and deposition accomplished via GIS analysis, and 3)calculating the tidal prism of the slough in GIS for comparison to previous estimates.

Marine Protected Area Control Site Suitability Analysis Based On Geomorphic Interpretation Of Multibeam Bathymetry Data Using GIS. [PDF] |
|
This project conducted a comparative study of the newly designated Carrington Point, Santa Rosa Island MPA and its control site. The comparison was based on a geomorphic analysis of high-resolution multibeam bathymetry data used to quantify the relative abundance and distribution of seafloor habitat within both areas to assess the suitability of the selected control site.

study tested the hypothesis that the dramatic decline in the kelp
forests of Santa Monica Bay, California, can be attributed, in part,
to sediment deposition and the resultant loss of near shore rocky
