Agassiz trawl
/ˈaeɡasɪz ˌtrɔːl/Chiefly Oceanography
noun
A type of beam trawl consisting of a net attached to a rigid frame with a hoop on either side, used to collect organisms dwelling on the sea floor.
- Unlike a standard beam trawl, an Agassiz trawl has a supportive beam for both the top and bottom of the net, which means that it will catch effectively even if upside down. It is used chiefly for research purposes..
Origin
Late 19th century. From the name of Alexander E. Agassiz, U.S. naturalist, who designed the trawl + trawl.
