Characteristics of mesozooplankton sound-scattering layer in the Pacific Summer Water, Arctic Ocean

This study investigated the variations in the sound-scattering layer (SSL) that were reflected from the mesozooplankton communities around the Northwind Ridge in the western Arctic Ocean. A multi-frequency acoustic survey was conducted to reveal the SSL distribution dominated by Arctic copepods in the early summer of 2010. The SSL distribution was well correlated with the salinity, nutrients and chlorophyll a (chl-a) associated with the features...
