No abstracts are to be cited without prior reference to the author.Large-scale circulation patterns in the N. Atlantic may partition the ocean basin into three semi-distinct gyre systems: the Norwegian Sea, the northern N. Atlantic, and the western N. Atlantic. Zooplankton entrained in these gyres may be ecologically, reproductively, and (perhaps) genetically distinct due to geographic isolation in different circulation systems and/or to isolation by distance. In an ongoing study of the distribution, abundance, and genetic variation of the ecologically important copepod Calanus finmarchicus in Icelandic waters, we are working to identify population genetic markers for mapping the species ˇ molecular genetic diversity and structure at appropriate scales and resolution in relation to water mass structure and ocean circulation patterns. We report here on the results from preliminary population genetic analysis using two different genetic markers: a single nucleotide polymorphism (SNP) in the DNA sequence of the ...
