CSA Colombia Deep Water Video

CSA recently provided, mobilized, and operated a deep water towed video system and all the ancillary equipment to conduct a video survey down to 2650m (8,700 feet) off the coast of Colombia. Included with the ancillary equipment was a slip-ring winch with 6,000 m of .68” EM cable, a Sonardyne USBL system, DGPS unit, and Hypack navigation software. After overseeing the shipping of the equipment spread from the U.S. to Colombia, CSA assisted with the mobilization and demobilization of the equipment to and from a Colombian offshore supply vessel of opportunity. The project data was collected in less than one week time and was a huge success, collecting over 2,000 photos and video of over 235 line km during the field effort. CSA operated all listed equipment and directed navigation of the vessel.

Building a Reef Habitat On the Outer Banks in North Carolina

CSA Ocean Sciences Inc. (CSA) has been contracted by the State of North Carolina Department of Transportation to conduct seagrass mitigation in anticipation of unavoidable impacts related to the Bonner Bridge construction project. The Bonner Bridge at Oregon Inlet on the North Carolina northern outer banks is a lifeline for tourism and tropical storm evacuation of the region but has reached its engineering limits and is currently under construction. The least impact associated with the new bridge alignment still requires recovery of at least 1.28 acres of highly productive seagrasses (eelgrass, Zostera marina and shoal grass, Halodule wrightii).

The Enigmatic Seagrass

Halophila johnsonii

Johnson’s seagrass, (Halophila johnsonii) is a species native to the Indian River Lagoon System (IRLS) and southeastern Florida coast. It is the first and only marine plant to carry the formal status of a Threatened Species under the Endangered Species Act. With this listing, this spatially and temporally dynamic plant has an elevated status of protection – which by default extends to a large portion of the coastal lagoon seafloor throughout the entire IRLS. As long as Johnson’s seagrass is listed under the ESA, many forms of coastal development are limited or prohibited and mitigation for its disturbance is not an option. We recently wrote an article for ECO Magazine (see link below) where you can learn more about this issue, along with the ins and outs of today’s DNA analysis methods.
