Coastal and Marine Survey Services
CSA International, Inc.’s Coastal and Marine Services business line provides extensive operational experience conducting multidisciplinary surveys in support of coastal and marine environmental programs and integrated efforts to collect physical data from the world's aquatic environments. CSA provides underwater photography (still and video); side-scan sonar; geophysical subbottom; sediment profiling; and bathymetric, hydrographic, and navigational positioning services. Remote sensing techniques, including underwater towed photographic systems, are used for habitat and biological community mapping that frequently involves the integration of multiple operational capabilities and data sets. CSA International, Inc. personnel are experienced in marine survey techniques and equipment operation and maintenance, as well as in data analysis and interpretation. Remote sensing data sets are geographically represented by utilizing GPS interfaced with specialized navigation and data acquisition software. The data acquisition and integration system formats various digital data for the generation of high-quality, GIS-compatible, and computer-aided drafting (CAD) products. CSA personnel also are proficient in processing digital data to produce mosaic images and maps of geo-referenced features.

CSA International, Inc. strongly believes regular assessments of shallow water systems are vital to maintaining a functioning cable system. Our standard inspection that evaluates potential risks or changes to the baseline site conditions consists of a qualified diver who records geo-referenced video footage of the site and an assessment of the Beach Manhole (BMH). Based on the findings of this inspection, CSA prepares a final report that summarizes the risk to the shallow water cables and recommends actions to eliminate or mitigate risks. If necessary, we will compile and submit a site-specific Shallow Water Repair Plan. Additionally, CSA International, Inc. is capable of immediate mobilization to perform a shallow water cable and terrestrial link inspection immediately following natural disasters, such as hurricanes or earthquakes, in order to examine the cable system for damage.
