This project was initiated to better understand the distribution of bottom sediment types, habitat biodiversity, and most importantly, human's impact on the bay bottom and its living resources. The project integrates the use of three types of acoustical systems: Roxann Seabed classification system, chirp sub-bottom profiling, and multi-beam bathymetric mapping. Verification of the acoustic data with bottom and sub-bottom sediments is performed through the collection of bra banc core samples and underwater video images.

The bottom sediment data and maps that was collected through the sediment sampling were collected and constructed to aid in the identification of essential fish Habitat (EFH), identify locations of potential borrow sites for beach replenishment, identify important locations for marine protection areas, and aid in the assessment of sediment dynamic of Delaware River and Bay.

Conceptual Consistency Ground truth information was collected at the time of the original surveys. In some cases, several grabs were made in the same general area to confirm the presence of a specific habitat. In the entire survey area in the Delaware River and Bay, over 600 sediment grab samples were collected for the bottom sediment verification and calibration of the Roxann sediment box plot . Samples were collected using a Petit Ponar, which has a sample opening of 6 inches x 6 inches, with a total sampling area of 36 in2. The petite ponar is a spring loaded sampler which pivots on an axis and when it encounters the bottom the retrieval rope is pulled and the ponar swings shut. The ponar will retrieve 2 to 6 inches, in depth, of sediments (depending on sediment type, harder and coarse sediments will constrict the ponar's penetration into the bottom). The retrieved sediment samples are then placed in a sampling bin and qualitatively described, noting the dominant sediment types, color, and sediment grain properties (sorting, grain maturity, and grain shape). Interesting features such as organic content (depending on sediment color), shell content and type, and anthropogenic debris are also recorded. Any organisms present are documented and these grab samples are then analyzed for their percentage abundances of sand, silt, and clay to determine sediment type. The sediment types are then correlated with their associated Roxann roughness and hardness clusters. Thus, the Roxann clusters can be used to develop a classification scheme for the sea floor.The box plot scheme used to classify the Roxann data for the bay an river areas are the current Delaware Bay benthic mapping project box plot which was constructed and verified by 540 grab samples collected during the 2004 thru 2008 field seasons. Sediment grab samples are collected from each ~ 5 sq. nautical miles (nm) field area (after the surveying has been completed) to verify any localized or regional differences that might cause variations in the clustering of the sediment classification.The roxann acoustic data was collected in a gridded trackline configuration, with tracklines spacing of 100 meters parallel to the shoreline and 200 meters perpendicular to the shoreline.This project is an extension of the work currently being performed in Delaware waters by DNREC's Delaware Coastal Program's Delaware Bay Benthic Mapping Project. 2008-01-01T00:00:00
