Description
Data is from an oceanographic survey performed from 10 to 18 August of 2010 off the South coast of Portugal. The sampling area was along the coast off Guadiana estuary to Cape S. Vicente between the longitudes 7º 30.0' W and 8º 59.6' W and between the 30 m isobath and 36º 30.0' N. Plankton stations were performed using a Longhurst Hardy Plankton Recorder (LHPR) sampler and Bongo nets. The LHPR was used in 16 stations to collect information on the water column distribution of the species. It was towed at 4 knots on oblique hauls from the surface to near the seabed or around 400 m at the deeper stations. Samples were collected at 25 m depth intervals. Mesh aperture of the collecting net and filtering gauze for all the hauls was 280 µm. A Bongo net with 60 cm diameter aperture and a mesh size of 335 µm was used in all the other stations. Additionally, in every station another oblique haul was performed using a Bongo net with 90 cm diameter aperture and a mesh size of 750 µm diameter. The Bongo nets were towed at depth integrated double oblique hauls at 2 knots from surface to 10 m above bottom or to 200 m at deeper stations. All plankton samples were preserved in 4% borax buffered formaldehyde prepared using seawater and subsequently sorted and analyzed for decapod larvae. The biovolume was determined by displacement volume method (Harris et al., 2000: https://wgze.net/methodology-manual/).
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 2,861 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
