Maps were produced showing one foot contour intervals and dense spot elevations. Accurate measurement of the sound velocity was especially critical on this project due to the dynamic water conditions near the mouth of the river, as well as the water depth. A sound velocity probe was mounted at the multibeam transducer to account for real time changes in sound velocity, and full sound velocity profiles were taken every two hours.

Patch tests and performance tests were completed within days of the survey to ensure that all offsets and calibrations were correct. We employed this system on our 26’ SeaArk survey vessel with twin 150 horsepower engines. The survey was used to detect any small shoals, lumps, or areas above the navigation channel limit of -50 feet MLLW that may require the contractor to send down additional divers to rake the area.ĭue to the high accuracy requirement of this survey, Degrove utilized the state-of-the-art R2Sonic 2024 multibeam system, along with dual-antenna RTK GPS for positioning and a CODA Octopus F175 Inertial Measurement Unit (IMU) for motion detection. This project upgraded an existing Type V magnetic measurement range.ĭegrove completed the post-construction survey of the one-half square mile project area, located on the river bottom of the Naval Station Mayport ship channel in the St.

Joe Kistel, director of TISIRI, said this project was the state’s first artificial concrete reef in an urban river. The Florida Department of Wildlife and Conservation also awarded CCA a $30,000 grant for the project.ĬCA enlisted TISIRI, a nonprofit organization that has installed artificial reefs off the coast of North Florida, to manage the project. The overall project, which doesn’t include the cost of three years of research on the reefs, cost $59,000 and was covered in part by $30,000 from country singer Kenny Chesney. The habitat enhancement project was started by the Jacksonville chapter of the Costal Conservation Association. The following excerpt was taken from an article published on, with the full article being available here. The reefs, located south of downtown Jacksonville, Florida, are designed to attract game fish. Degrove provided side scan surveys of two recently-constructed artificial reefs in the St.
