FalkenhaugNancy Copley from Woods Hole Oceanographic institution, MA, USA, has visited the Institute of Marine Research, Flødevigen Research station (Arendal), Norway, 7 – 11 March 2005. The aim of the visit was to sort out selected groups of zooplankton from MAR-ECO samples collected on the mid-Atlantic Ridge, June 2004.

This work is a cooperation between MAR-ECO and the CoML project Census of Marine Zooplankton (CMarZ).

The samples will be brought to Prof. Ann Bucklin at the University of New Hampshire, NH, USA for species identification and DNA sequencing.
This will provide MAR-ECO with valuable information on species diversity and reveal cryptic or undescribed species. The molecular data will be incorporated into the OBIS database by CMarZ.

Groups that have been selected for molecular analysis include euphausiids, siphonophores, medusae and copepods. Copepod genera that are of special interest are the Aetideidae, Metridiidae, Heterorhabuds, Paraeuchaeta and Pleuromamma. 5 of the 6 known N. Atlantic species of Pleuromamma were found in the zooplanktonsamples from the MAR. For some of the species, this work will provide the first DNA sequences ever.

Nancy Copley is a Research Associate at the WHOI. Her specialty is zooplankton taxonomy, especially crustacea and Calanoid copepods in particular; and has experiences with zooplankton from Gulf Stream Rings and deep sea hydrothermal vents.
