Spotlight on Sandy

Oceanographic Gear Retrieved from Offshore of Fire Island, New York

 previous story | next story

In April 2014, U.S. Geological Survey (USGS) scientists retrieved oceanographic instruments that had been collecting data for two months off Fire Island, New York. Recovery of the instruments wraps up the field portion of an effort by the USGS Coastal Change Hazards Project to study how sediment moves in response to storms (see Sound Waves article, “Update on Oceanographic Study Offshore of Fire Island, New York”).

Above: Screenshot from video clip showing gear recovery aboard the research vessel Connecticut offshore of Fire Island, New York. The clip shows recovery of one large tripod, two smaller tripods, and two yellow surface buoys, one of which held a set of meteorological instruments. The weather was rather calm and made for smooth retrieval of the equipment. View the clip, produced from GoPro® images by Peter Traykovski (Woods Hole Oceanographic Institution), on YouTube.

Instrumented tripods deployed on the seafloor in from February to April 2014 (see Sound Waves article, “USGS Deploys Oceanographic Gear Offshore of Fire Island, New York”) measured ocean currents, water temperature and salinity, suspended-sediment concentrations, and other parameters that could shed light on sediment transport. Surface buoys protected the seafloor tripods, and some held instruments to measure meteorological variables, such as air temperature and wind speed and direction. A specialized wave buoy was deployed at the site farthest from shore to measure the height, period, and direction of surface waves and telemeter the data to the Coastal Data Information Program (CDIP)

All of the instruments except for the wave buoy were recovered in April. The wave buoy will be left on site for several years—its data can be viewed in near-real time at the CDIP website, buoy 207—Fire Island Nearshore NY, or at the National Data Buoy Center, Station 44094—Fire Island Nearshore, NY—207. Learn more about the wave data on this FAQ page.

Three cruises onboard the research vessel (R/V) Connecticut were required to gather all the gear and transport it back to the dock at the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. Operations ran during daylight hours and were recorded using a GoPro® camera. Project collaborator Peter Traykovski (WHOI) merged images taken at 30-second intervals to create a short (50-second) video clip showing a full day of recovery activities, “FireIsland2014RecoveryGopro.”

Project scientists are currently analyzing the accumulated data. Stay tuned for further developments!
