Seamount. Their goal was to investigate and find ways to reduce the impacts of fishing and improve knowledge of the distribution of tunas, and how they are impacted by fishing activity. It also performed routine maintenance on the HARP. On April 21, 2007, another cruise embarked for Cross Seamount. This cruise's goal, led by Reka Domokos and again on the Oscar Elton Settle, was to test and develop new methods for estimating fish populations using bioacoustics, specifically that of the bigeye tuna. The study was also keyed to try to determine the relationship between seamounts and the local fish population. On April 15, 2008, another cruise embarked, to study the bigeye tuna population and their migratory patterns. The researchers, again on the ship Oscar Elton Sette, investigated the seamount waters, measuring the number of bigeye tuna and the prey species that frequent the area.
