The ARCWEST (Arctic Whale Ecology Study) cruise took place on board the R/V Aquila. The cruise began in Kodiak, AK on 13 August 2013 and ended in Kodiak on 18 September 2013. Chief Scientist was Dr. Catherine Berchok from 13 August until 9 September and Jessica Crance from 10 September until 18 September. The survey team consisted of 17 scientists representing eight different laboratories (for full personnel list, see Appendix 1). In summary, a total of 23 passive acoustic and 14 oceanographic moorings were retrieved, and 25 passive acoustic and 17 oceanographic moorings were redeployed. Five satellite tags were deployed on gray whales, four of which transmitted successfully. A total of 48 hydrographic and 32 zooplankton stations were conducted, nine drifters were deployed, 24 hour passive acoustic monitoring (via sonobuoy deployments) occurred, and over 1,500 nm were surveyed for marine mammal and bird observations.
