CMS provides high-resolution side-scan sonar surveys for seafloor mapping, target identification, and habitat assessment. Utilizing both pole-mounted and towed systems, CMS delivers reliable imagery across a range of substrate types and water depths. The CMS team employs multiple systems operating at a range of frequencies, including ~450 kHz for broader coverage, achieving swath widths of up to 100 meters (300 ft) per channel, and 800 to 1075 kHz for high-resolution mapping and detailed imaging. Data deliverables include fully processed sonar datasets and GIS-integrated mapping products tailored to project needs.

CMS provides multibeam and single beam bathymetric surveys to accurately measure and map underwater topography across freshwater, estuarine, coastal, and marine environments. Utilizing advanced sonar systems and experienced field personnel, CMS delivers efficient, high-resolution depth data suitable for a wide range of applications. Bathymetric surveys can be integrated with topographic data collection to produce seamless land-to-water elevation models. Deliverables include fully processed datasets and GIS-integrated mapping products tailored to project requirements.

CMS provides marine debris detection and removal services, with extensive experience targeting derelict fishing gear and other submerged debris across coastal environments. To date, CMS has supported the removal of over 22,500 derelict crab traps from Louisiana waters through contract work, partnerships, and collaborations with state and federal agencies and environmental organizations. CMS specializes in the use of side-scan sonar to locate unmarked and submerged debris, including traps that have separated from their surface buoys. Recovery operations are conducted using proven hook and grapple methods. In addition to crab traps, CMS has located and removed a range of marine debris, including derelict fishing gear, vessel components, and structural materials.

CMS provides underwater imaging and remotely operated vehicle (ROV) services to support inspection, visualization, and data collection in submerged environments. Compact and highly maneuverable systems allow for efficient deployment across a range of conditions, including low-visibility and confined environments. ROV systems are equipped with high-definition (1080p and 4K) cameras and integrated lighting to capture clear, real-time video and imagery. All footage is recorded for post-processing and analysis, with optional integration into visualization platforms to support rapid assessment, fish counts, and project documentation.

CMS provides marine technical support for the setup, operation, and troubleshooting of hydrographic and oceanographic instrumentation. Services range from short-term mobilization and system integration to extended field deployments, supporting a wide variety of project needs. The CMS team has experience with a broad range of systems, including echo sounders, ADCPs, acoustic survey equipment, sub-bottom profilers, CHIRP systems, flow-through systems, thermosalinographs, CTDs, and related instrumentation.
