Environmental Monitors on Lobster Traps and Large Trawlers
More than one hundred commercial fishing vessels on the Northeast Shelf now have oceanographic sensors installed on their fixed and mobile gear. Some have experimented with tide gauges, acoustic listening devices, cameras, satellite-tracked drifters, current meters, and salinity monitors but the primary focus has been collecting bottom temperatures. While some gear are fitted with internally-recording devices that have returned more than two decades of hourly data from fixed locations, about half the vessels are fitted with satellite transmitters so that ~20,000 hauls have reported bottom temperatures in realtime. In the past year, several vessels are now equipped with water column profilers to document the vertical stratification of temperature and a few are collecting records of bottom dissolved oxygen. The primary goal is to feed the data to both ocean models and stock assessment models.
While the project was initiated at NOAA's Northeast Fisheries Science Center in 2001, the Gulf of Maine Lobster Foundation leads the administration/operations along with several partners. The original NOAA eMOLT page is here.
