GEOGRAPHIC REGION: North Atlantic Ocean PERIOD OF RECORD: 30,000-0 yr BP LIST OF FILES: surface.dat, cores.dat, age.dat,names.dat, coord.dat DESCRIPTION: (notes from M. Barash) This diskette contains the data of the planktonic foraminifera counts in the Atlantic Ocean sediments. The micropaleontological analyses were made in the Laboratory of paleoecology and biostratigraphy of the P.P.Shirshov Institute of Oceanology, Russian Academy of Sciences, Moscow, by M.S.Barash, N.S.Blyum and N.S.Oskina. Some samples were carried out by other Barash's collaborators. These data are a part of the available data and are chosen especially for elaborating of a new paleotemperature method. Many data were used for the Quaternary paleoceanographical reconstructions (Barash,1988; Barash e.a.,1983; etc.). For foraminiferal analyses the sediment fraction coarser than 0.1 mm was used. Usually it was the fraction of the granulometric analyse. In other cases the sediment samples were washed through 0.1 mm sieve especially for a foraminiferal analyse. 5-10 g of the sediment was usually used. Then the fractions were dried, thoroughly mixed and divided until the remaining split contained at least 300 tests. All components were identified and counted in this split. Additionally, all the size fraction of the sample was examined under microscope to discover rare species that might be omitted from the split. (In this case in the data files the percentages of these species are shown as 0.05). The file COOR.DAT contains the coordinates of the bottom surface and core samples. The station number includes the letter simbol of the researh vessel and sometimes the cruise numbers. The samples were received in 1958-1989 years. E - R/V "Equator" K - R/V "Akademik Kurchatov" L - R/V "Michail Lomonosov" M - R/V "Dmitriy Mendeleev" MK- R/V "Akademik Mstislav Keldysh" S - R/V "Sedov" (S1, S2, S4 are its cruises 1,2,4) P - R/V "Polus" A - R/V "Nikolai Kolomeytsev" Latidudes and longitudes are given in degrees and minutes, the South latitudes and East longitudes are shown as "-". The bottom depths are in meters. The file NAMES.DAT contains the planktonic foraminifera species names. The species are arranged in the "temperature sequence" beginning from the most cold-water species to the most warm-water one (Barash et al.,1983;Barash, 1988; e.a.). The taxonomy of F.Parker (1960, 1962) with the some corrections proposed by A.W.H.Be (1967,1977) is used. Records 1-29 are the species names. Left coiling (sin.) and right coiling (dex.) forms of two species (Gq.pachyderma and Gr.truncatulinoides) were counted separately and placed under different numbers in the "temperature sequence" according to data on connection between their distribution and the annual temperature. (Records 1 and 5, and 9 and 12). Record 22 are Globigerinoides tenellus Parker and Globigerina rubescens Hofker counted together because their small tests are difficult to distinguish. Record 30 are "other" rare or unidentified species. Record 31 are Gr.truncatulinoides left coiling and right coiling forms counted together in some samples. The records 1-31 are used for species names in the left columns of the data files "SURFACE.DAT" and "CORES.DAT". The file SURFACE.DAT contains the results of the planktonic fo- raminifera tests counts in the bottom surface samples,in percents. The file headed by station numbers. Left columns (2-3) show the species names under numbers 1-31 as described above. In the cases if some of species are not found their numbers are not written. Other columns are species tests percents in the samples. Since rare species counted in whole coarse ( > 0.1 mm) fraction of sediment are added to split counts as 0.05% the sums sometimes are more 100%. The file CORES.DAT contains the results of the planktonic foraminifera tests counts in the samples from 15 cores. All the cores are obtained by gravity tubes. They represent the foraminifera thanatocoenoses changes on the different latitudes of the Atlantic Ocean mainly during the Late Quaternary. Each data block is headed by core number. The continuations and ends are also shown. Next line defines the depth in core (cm). Left column defines the species number according to the file NAMES.DAT. The file AGE.DAT contains the results of the C-14 dating of the cores. All C-14 data were obtained by Dr.V.M.Kouptsov (P.P.Shirshov Inst.Oceanology, Moscow). For core L-66 two dates by Th-230 and Pa-231 method are shown (Arslanov e.a.,1988). The file is a usual table.
