CSA Ocean Sciences Inc.’s (CSA’s) multidisciplinary programs range from nearshore monitoring surveys to full ocean depth studies. Visual data collection, photography, and video play a significant role in successfully fulfilling the scientific requirements of these programs. CSA owns and utilizes subsea hand-held cameras, video systems, and remote camera systems such as towed platforms and remotely operated vehicles (ROVs).
Our photographic/video data collection methods vary significantly, depending on project requirements and location. In shallow water (less than 30 m), we use divers experienced in conducting repetitive video transects or taking still photos of quadrats, which enables further analysis and determination of the identities and relative abundance of marine organisms. Our diving staff regularly travels the world to collect photographic data in order to monitor various long-term programs such as coral relocation, seagrass restoration, and pre- and post-construction surveys or to document a damaged submarine telecommunications cable as part of the repair process.
For deepwater projects, CSA uses various types of ROVs, depending on project needs. Between 2010 and 2014, CSA conducted numerous deepwater ROV dives in the Gulf of Mexico and collected massive amounts of video and still photographic data. The ROVs utilized for this large, challenging project ranged in size from a small inspection vehicle to extremely large hydraulic work class vehicles.
