The purpose of the original data collection was the study of Antarctic krill population (Euphausia superba Dana) and other main pelagic component of South-Orkney sub-region Scotia Sea and Bransfield Strait. Dataset includes zooplankton data (limited to order Tintinnida Kofoid and Campbel, 1929) collected during First Ukrainian Antarctic Expedition (March-April 1997) on board of R/V Krenkel. Samples were collected from different depths (25, 50, 70, 75, 100, 135 and 150 m) by bathometer and bucket from the surface. The volume of the sample - 5 L. Samples were concentrated by direct filtration to a final volume of 70 - 100 ml and fixed by formalin. Further samples were concentrated to 10-20 ml and analyzed with optical microscope at magnification x 12.5. At IBSS, the data were digitized from paper processing books, quality-controlled and transformed to comply with the Darwin Core/OBIS Schema. Funds for data operations were kindly provided by the Census of Marine Life International Cosmos Prize Fund, through a grant to Rutgers University.
