ObjectivesThe GeneFlow Cruise was a collaborative, interdisciplinary expedition to collect data and specimens necessary for the study of the interactions between oceanography and genetic structure of marine populations. Populations of the principle marine resource species (krill, fish and squid), as well as other planktonic fish larvae and invertebrates were sampled around the periphery of the Scotia Sea to test levels of genetic isolation and determine genetic exchange, or gene flow, between them. A substantial collection of fish larvae, krill, juvenile cephalopods and other marine invertebrates was made, and the oceanography of the water masses in which the samples were taken was thoroughly characterised in all areas where biological sampling took place. Heavy pack ice meant that the ship was not able to proceed from the South Sandwich Islands to the South Orkney group as originally intended so no samples were collected from that area.
