Latitudinal and bathymetric patterns in the distribution and abundance of mesopelagic fish in the Scotia Sea
Mesopelagic fish are a key component of the pelagic ecosystem throughout the world's oceans. Opening and closing nets were used to investigate patterns in the distribution and abundance of mesopelagic fish from the surface to 1000 m on a series of transects across the Scotia Sea from the ice-ed...
