MarFac is the operational arm of PCMSC. MarFac staff provide engineering, mechanical, and electronics expertise for field operations along the coast, in the nearshore environment, and in the deeper waters of the ocean.

Ocean engineer Gerry Hatcher, of the USGS Pacific Coastal and Marine Science Center (PCMSC), sits at a desk on board the USGS boat Sallenger. He and a team of scientists from PCMSC and sister team St. Petersburg Coastal and Marine Science Center are near Eastern Dry Rocks reef off the coast of Key West National Wildlife Refuge in Florida. Gerry is keeping notes while the special camera system that he invented and developed is towed in the water.

The system is called “SQUID-5” (Structure-from-Motion Quantitative Underwater Imaging Device with 5 cameras). SQUID-5 is towed over an area of interest, in this case a coral reef ecosystem, to collect high-resolution georeferenced imagery that is used to make 3D maps of the seafloor.

These high-res maps allow the USGS to detect millimeter-scale changes in seafloor elevation and coral reef structure. This information can be used to help track the progress of restoration efforts being done by partners such as the NOAA Florida Keys National Marine Sanctuary over the next two decades.

Jenny McKee and Peter Dal Farro of the USGS Pacific Coastal and Marine Science Center’s Marine Facility swing a pair of seismic sources, also called air guns, and the gun hanger, out over the water to deploy them during the 2018 MATRIX cruise.

Marine engineering technician Pete Dal Ferro sets up a newly acquired, portable, single-beam echo sounder on the San Lorenzo River in Santa Cruz, California. The new device, called CEESCOPE, collects bathymetric (depth) data and also records features of the subsurface. All the components are easy for one person to set up and operate, with GPS and an LCD touch screen. This day survey is part of ongoing, seasonal surveys in the nearshore regions of Monterey Bay to help characterize the sediment budget of the area. Credit: Andrew Stevens, USGS Pacific Coastal and Marine Science Center
