Finding Ocean Life with Sonar
The Midwater Ecology lab has been exploring the midwaters of Monterey Bay for the last week on the Western Flyer. On this expedition, they have been working with the ROV pilots to attempt to use the sonar on the ROV to detect midwater animals. 
The pilots are testing how increasing the pulse length on the Mesotech sonar enables the scientists to detect more midwater animals in order to try to estimate abundances. For example, they could estimate the size of krill swarms. With the ROV they can ground-truth the organisms the sonar is imaging. 
This bright sonar hit is an exceptionally large vampire squid, Vampyroteuthis infernalis.
