Abandoned, lost or discarded fishing gear — often called ghost gear — can contribute up to 76% of all marine debris found during beach cleanups.Estimates of the weight of abandoned fish gear vary widely by region and by type of gear used. One study retrieved 14 tonnes from the northwestern Hawaiian Islands. In one fishing region in Nova Scotia, an estimated 22 tonnes of fishing gear remains at sea.

Surveyors Map Sunken Liberty Ship off Texas Coast

U.S.-based marine data acquisition services company TDI-Brooks said it recently mapped the Liberty Ship George Vancouver off Freeport, Texas while out on a seabed survey project with the R/V Brooks McCall. The multiple multi-phase geophysical and geotechnical site surveys program consisted of pipeline routing and subsea structures to facilitate route and project design for offshore developers.Equipment used to map the ship was a Teledyne Reson SeaBat T-20 multibeam sonar with integrated Applanix POSMV for Motion. Applying the mesh tools to the multibeam survey shows an example of the shipwreck.Texas
