Statement of Need: Rayfin Single Channel Inspection Camera Brand Name or Equal

Introduction:

The U. S. Geological Survey (USGS) Woods Hole Coastal & Marine Science Center (WHCMSC) has the need to procure a Rayfin Single Channel Inspection (SCI) Camera as part of the Sea Bed Observation Sediment Sampling System upgrade. The Aquorea Mk3 LED lamps/strobes and MantaRay Parallel Lasers have also been identified as a need as they are critical parts of the Rayfin (SCI) Camera system. The proposed procurement is needed to upgrade the capability of digital seafloor mapping of U.S. near shore coastal waters and inland waterways using high definition position and time tagged still photographs and video. Collection of high definition time and position tagged still photographs and video data, when coupled with an understanding of sub-surface geology, is fundamental to USGS research and provides a framework for addressing coastal erosion, coastal evolution, shoreline/coastal response to large-scale storm systems, offshore resources, and sediment transport studies. The Aquorea Mk3 LED and MantaRay Parallel Lasers interface directly with the Rayfin SCI Camera to provide the user control of the system components through the same software package. The Rayfin SCI Camera provides power to the Aquorea Mk3 LED and MantaRay parallel lasers simplifying system design and lowering the overall cost for components. The ability for the Aquorea Mk3 to operate as both an LED and a still photo strobe is unique to the system and fills a need that would otherwise require two different pieces of equipment, representing a cost savings to the government.

The WHSC requires the Sea Bed Observation Sediment Sampling System of which the Rayfin Single Channel Inspection Camera system is a critical component to conduct digital photographic and video mapping of our coastal oceans, estuaries and coastal shoreline. The addition to the existing system is a more cost-efficient means to maintain these capabilities than procuring an entirely new system.
