A Matter of Density

New Review

Larvae transportation on the New England seamounts is based on the density of the water. Scholars calculate density and graph salinity versus temperature to better understand the distribution of organisms in a water column. Discussions of the relationship between density, temperature, salinity, and pressure lead to a better understanding of sigma-t.
