Zooplankton monitoring RADIALES - section off Santander (N Spain, Cantrabrian Sea); oceanic (station depth 850m)

Zooplankton time-series from the time-series monitoring programme RADIALES, done by IEO at different stations in the Northwest and North Iberian Shelf. Measured variables:

• Size-fractionated biomass, for size-fractions 200-500, 500-1000, 1000-2000 and >2000 µm ESD (equivalent spherical diameter).

• Water-column integrated abundance (individuals/m2) and/or concentration (individuals/m3) of meso-zooplankton (to the species level whenever possible.

  Collection method: Juday-Bogorov plankton net type of 250 micrometer mesh-size; double oblique hauls between the surface and 5m above the bottom depth.

  Sampling depth: Water-column integrated hauls from 5 m above the bottom (or a maximum of 100m) to the surface

  Preservation of samples: 4% sodium borate-buffered formalin-seawater solution.

  Analytical method: Identification / Enumeration under the stereomicroscope. Taxonomic classification is carried out by different experts depending on location.

  Format of the files: csv file; matrix of depth-integrated water column abundance (individuals/m2 and/or individuals/m3) by motnh and by taxonomic affiliation (to the species level whenever possible), for each sampling station (latitude / longitude).

  All data are organised in a common Access database
