SCANS I cetacean sightings 1994

Point file data on all sighting events and associated parameters and data from the survey.
The Small Cetacean Abundance in the North Sea (SCANS) project was initiated in 1993. Dedicated line transect shipboard surveys were conducted between 27 June and 26 July 1994. Transects covered 20,000km2 in an area of 890,000km2. The survey area included the region specified in the Agreement on Small Cetaceans Of the Baltic And North Seas (ASCOBANS) (excluding most of the Baltic Sea proper) and the Celtic Sea. The shipboard methodology involved simultaneous survey from two independent observation platforms, one of which searched farther ahead of the vessel than the other. There were two observation platforms on each of the nine vessels participating in the SCANS project. Three species dominate the dataset; the harbour porpoise (Phocoena phocoena), white-beaked dolphin (Lagenorhynchus albirostris) and minke whale (Balaenoptera acutorostrata). The dataset is a point file containing information on all sighting events from each platform on each vessel during survey effort. The effort file contains the start and end positions for each leg of survey effort for each vessel and associated parameters. The data have been extracted from the Joint Cetacean Database.

The status of small cetaceans, particularly the harbour porpoise, in the North Sea and adjacent waters was of considerable concern due to substantial incidental bycatch in fishing operations, declines in the number of stranding records and incidental sightings in coastal waters and from the possible risk of contaminants and pollution. The objective of SCANS was to provide essential information for conservation, management and future monitoring of small cetaceans by i) identifying concentrations of P. phocoena and other small cetaceans and ii) generating precise and unbiased abundance estimates.
Cetacean strandings in the northern Black Sea and the Sea of Azov

More than 1220 strandings of Black Sea cetaceans have been recorded on the coasts of Crimea peninsula during the period from 1989-2010.
More than 1220 strandings of Black Sea cetaceans – harbour porpoises, common dolphins and bottlenose dolphins – have been recorded on the coasts of Crimea peninsula during 22 years (1989-2010) by the cetacean stranding network coordinated from the Brema Laboratory. The dataset includes information about  live-stranded animals and findings of cetacean carcasses. The data make it possible to ascertain several cetacean mass mortality events occurred in different years of the monitoring.
Phytoplankton in longitudinal east-west transect of the Mediterranean Sea,1999

The scope of this study was to explore the diversification of the phytoplankton community structure and related ecological determinants along a large scale (3188 km) longitudinal transect, covering the region from eastern Mediterranean to Western Basin. Sampling was performed during the period June – July of 1999. Six stations were located in the Eastern Basin, one station in the Sicily strait and two stations in the Western Basin.A total of 216 species were identified(48 diatoms, 112 dinoflagellates and 56 coccolithophores).
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.

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.
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.
