Phytoplankton in longitudinal east-west transect of the Mediterranean Sea,1999.

Study Extent

This dataset is based on a large scale longitudinal transect from eastern Mediterranean sea to the Western Basin, in June and July 1999.

Sampling

Samples were collected from routine hydrocasts using a CTD rosette sampler from 1, 10, 20, 50, 75, 100 and 120 m. Temperature and salinity were recorded using a Seabird Electronics SBE-911+ CTD profiler. Samples for chlorophyll a determination (2 L from each sampling depth) were filtered on board through 0.2 mm polycarbonate Millipore filters and kept frozen until analysis in the laboratory with a TURNER 00-AU-10 fluorometer. Samples for the determination of nutrients were collected in 100 ml polyethylene bottles and kept at -20oC, until their analysis in the laboratory with a Bran+Luebbe II autoanalyser. Phosphate was measured with a Perkin Elmer Lambda 2S UV/VIS Spectrometer.

Quality Control

Stations were plotted on Google earth for a visual check. Taxonomic quality control was done using the online taxon match tool of WoRMS.
