Broadbeach Marine Vegetation and Sediment Survey, CA

eTrac completed a detailed and highly sensitive environmental and sediment classification survey for Rincon Consultants as part of their work on the Broadbeach Restoration Project offshore of Malibu, CA. eTrac acquired data using a myriad of data collection techniques and sonars including a mounted dual frequency sidescan sonar, ultra-high density and high-resolution multibeam sonar with backscatter and water column, as well as multispectral multibeam sonar data. In-depth analysis of the data was completed by our in house team of experienced marine scientists to determine accurate extents of rock outcroppings, gravel, sand, and mud sediments. In addition, marine vegetation were identified using methodology and sonar analysis techniques developed in partnership with sonar manufacturers. This project allowed a new level of sediment determination and analysis to be conducted through the use of multispectral data acquisition and processing.
