Distribution of halacarid species in sediment surface samples of Josephine Bank and Great Meteor Bank, Northeast Atlantic (Table 4)

In 22 samples, 6 from Josephine Bank and 16 from the Great Meteor Bank, 14 halacarid species were found and described. Halacarus spiniger n. sp., Copidognathus magniporus n. sp., Arhodeoporus lineatus n. sp., A. brevocularis n. sp., Coloboceras karamani n. sp., Scaptognathus minutus n. sp., and Atelopsalis newelli were hithero unknown. Acaromantis squilla Trouessart & Neumann and Atelopsalis tricuspis Trouessart were redescribed. Four larvae, probably belonging to Copidognathus longips Bartsch, C. tricorneata (Lohmann), Lohmannella falcata (Hodge), and Atelopsalis newelli n. sp. were described, two Scaptognathus larvae could not be identifird. To date only three species, Copidognathus tricorneata, Lohmannella falcata, and Scaptognathus minutus, have been found on both seamounts.

Spatial distribution of key zooplankton species using continuous plankton recorder (CPR) data from the North Atlantic (2000-2009)

The continuous plankton recorder (CPR) survey is an upper layer plankton monitoring program that has regularly collected samples, at monthly intervals, in the North Atlantic and adjacent seas since 1946. Water from approximately 6 m depth enters the CPR through a small aperture at the front of the sampler and travels down a tunnel where it passes through a silk filtering mesh of 270 µm before exiting at the back of the CPR. The plankton filtered on the silk is analyzed in sections corresponding to 10 nautical miles (approx. 3 m**3 of seawater filtered) and the plankton microscopically identified (Richardson et al., 2006 and reference therein). In the present study we used the CPR data to investigate the current basin scale distribution of C. finmarchicus (C5-C6), C. helgolandicus (C5-C6), C. hyperboreus (C5-C6), Pseudocalanus spp. (C6), Oithona spp. (C1-C6), total Euphausiida, total Thecosomata and the presence/absence of Cnidaria and the Phytoplankton Colour Index (PCI). The PCI, which is a visual assessment of the greenness of the silk, is used as an indicator of the distribution of total phytoplankton biomass across the Atlantic basin (Batten et al., 2003). Monthly data collected between 2000 and 2009 were gridded using the inverse-distance interpolation method, in which the interpolated values were the nodes of a 2 degree by 2 degree grid. The resulting twelve monthly matrices were then averaged within the year and in the case of the zooplankton the data were log-transformed (i.e. log10 (x+1).
