This data contains abundance, length, and life history data of four species of Calanus copepods. The data is a compilation of 3 cruises of the MV OB carried out by the Soviet Antarctic Expedition during the IGY (1955-1958). The surveys paid close attention to obtaining complete data on the populations and distribution of the adult stages of Copepoda. Two types of plankton nets were used; Juday net with mesh size No. 38 and the K100 net with mesh size No. 9 in the cylindrical part, No. 15 in the upper part and No. 23 or 38 in the lower part of the net. This paper also includes excellent cruise and Calanus abundance maps as well as extensive station information. This data is a summary of three cruises of the MV OB by the Soviet Antarctic Expedition. The article summarizes the distribution of euphausiid species and includes maps of their distribution based on collections of the OB and published data. The euphausiids were mainly sampled with a K100 net: 100 cm diameter, cylindrical part with No. 9 mesh, conical part with No. 15 mesh in the upper part and No. 23 or 38 in the lower part. A few other samples were taken with a Nansen net(50 cm diameter, cylindrical part No. 15 mesh, conical part No. 23 mesh), a Juday plankton net, a Bogorev-Rass net, or a ring-trawl. Most of the samples were taken by oblique hauls.

Thirty-nine plankton samples were collected at the Drift Station "Arlis II" at the north of Greenland in the Arctic Ocean during the period from June to December, 1964. From the samples thirty-two species of copepods were identified, of which Calanus glacialis, C. hyperboreus, Microcalanus pygmaeus, Spinocalanus abyssalis, Metridia longa and Oithona similis were major components. The maximum plankton biomass throughout the period was observed in July when C. hyperboreus was predominant. The plankton population during day season (light season from June to August) was characterized by abundance of C. hyperboreus, M. pygmaeus and O. similis, while the population during night season (dark season from September to December) was characterized by abundance of M. pygmaeus and O. similis. Developmental stages of C. hyperboreus were collected in bulk in summer, suggesting that this species was breeding under the permanent ice floe.

Region(s) of distribution of Pacific Cod (Gadus macrocephalus) Tilesius, 1810 in the Arctic as digitized for U.S. Geological Survey Scientific Investigations Report 2016-5038. For details on the project and purpose, see the report at https://doi.org/10.3133/sir20165038. Complete metadata for the collection of species datasets is in the metadata document "Dataset_for_Alaska_Marine_Fish_Ecology_Catalog.xml" at https://doi.org/10.5066/F7M61HD7. Source(s) for this digitized data layer are listed in the metadata Process Steps section. Note that the original source may show an extended area; some datasets were limited to the published map boundary. Distributions of marine fishes are shown in adjacent Arctic seas where reliable data are available. The data were clipped to show only the marine distribution areas although some species also may have an inland presence.

Time series data on fluxes, average weight, and isotopic compilation of perennially abundant planktonic foraminifera of the Sargasso sea, near Bermuda, North Atlantic. Thirty one sediment trap deployments at 3200-m and 1000-m above the sea floor from April 1978 to May 1984. Forms described are Globigerinoides ruber, Globigerinella aequilateralis, and Orbulina universa. These data were collected by Dr. W. G. Deuser, Woods Hole Oceanographic Institution (WHOI), under NSF Grants OCE 76-21280, OCE 78-19813, OCE 80-24130, OCE 82-19588, and OCE 85-09155. One floppy disk containing planktonic foraminifera data submitted to NODC has been copied to current NODC data storage media.
