ARCTIC Analysis of Arctic Cod Movements in the
ABSTRACT. A study was conducted to investigate distribution and abundance of arctic cod in the nearshore region of the Beaufort Sea. Data collection methods included 3 m otter trawl and hydroacoustic surveys. Temperature and conductivity measurements were taken throughout the study area on a regular...
