Abstract:
The Arctic Ostracode Database provides species census data for about
100 species of benthic marine Ostracoda from modern surface and late
Quaternary sediments from various parts of the Arctic Ocean and
adjacent seas. Ostracodes are a microfossil group of bivalved
Crustacea that secrete a calcareous shell commonly preserved in
sediments in the Arctic region. Because many ostracode species have
ecological limits controlled by temperature, salinity, oxygen, food
and other factors, they can provide an important tool for
paleoceanographic reconstruction in the Arctic. Some recent
applications of ostracodes to understanding Arctic Ocean history
include Briggs (1983), Reimnitz et al. (1983, 1992), McDougall et
al. (1986), Clark et al.(1990), Pak et al. (1992), Brouwers et al.
(1991), Cronin et al. (1993, 1994, 1995), Penney (1993a,b), Nurnberg
et al. (1994), and Briggs and Mudie (in prep.).
Purpose:
Ostracodes are a microfossil group of bivalved Crustacea that
secrete a calcareous shell commonly preserved in sediments in the
Arctic region. Because many ostracode species have ecological
limits controlled by temperature, salinity, oxygen, food and other
factors, they can provide an important tool for paleoceanographic
reconstruction in the Arctic.
Supplemental_Information:
All files are tab-delimited ASCII text, meaning that columns are
separated by the tab character (ASCII 9). It should be
straightforward to import these data into a spreadsheet or database
application, provided the tab characters are preserved during the
transfer across the network. To ensure that the tabs are preserved,
load the files directly to your local disk, don't save them from a
web browser's display window.

Data_Set_Credit:
We are grateful to the shipboard scientists and crews of cruises who
obtained Arctic cores and samples that provided the material for this
database. We are also especially appreciative of the following colleagues
who have freely and kindly provided material for ostracode study: Dr. J.
T. Andrews, K. Foley, Prof. D. Fütterer, Dr. A. Grantz, Dr. S. Ishman, Dr.
E. Reimnitz, Dr. P. Barnes, Dr. S. Lehman, Dr. A. Mackensen, Dr. D.
Nurnberg, Dr. L. Polyak, Dr. R.Z. Poore, Dr. R. Spielhagen, Dr. R. Stein,
Prof. J. Thiede, Dr. C. Vogt, Dr. J. Wollenburg. Much of the ostracode
research was supported by the U.S. Geological Survey (USGS) Global Change
and Climate History Program, in collaboration with INSTAAR (University of
Colorado) and the Institute of Earth Studies, Aberystwyth, (University
College, Wales), and with assistance from the Alfred Wegener Institute
(Bremerhaven) and GEOMAR (Kiel). Most of the taxonomy of this database
was agreed upon at a conference on deep-sea Ostracoda held in summer,
1993, at the USGS in Reston, Virginia, sponsored by the USGS Global Change
and Climate History Program.

The data set was compiled on a Macintosh IIci, using Microsoft Excel
and Microsoft Word.
