DESCRIPTION:
DSDP Site 219
Latitude: 9o01.75' N
Longitude: 72o52.67' E
Bathymetry: 1764 m
Deep Sea Drilling Project (DSDP) Site 219 was drilled during Leg 23 
(Whitmarsh et al., 1974), and lies on the crest of the Laccadive-Chagos Ridge 
in the northwestern Indian Ocean (southeastern Arabian Sea).

First column: (sample)  sample name in ODP standard format. 
Second column: (mbsf) depth of sample down hole in meters below sea floor, 
given at two values behind the decimal; 
Third column (species used for isotope analysis): G. p.: Globocassidulina pacifica; 
O.u.: Oridorsalis umbonatus; 
C.k.: Cibicidoides kullenbergi; C. w.: Cibicidoides wuellerstorfi. 
Fourth column (d18O): oxygen isotope data on the benthic species named in the third column. 
Fifth column (d18O*): carbon isotope data on the benthic species named in the third column. 
Sixth column (d13C*): adjusted oxygen isotope data; adjustment according to species. 
Seventh column: adjusted carbon isotope data; adjusted according to species. 
All isotope data are given with respect to PDB; two numbers behind the decimal point. 
Eighth column (numerical age): numerical age according to the time scale of 
Berggren et al., 1995; age model in Gupta and Thomas. 
Ninth column (Cluster, Assemblage): gives the results of the multivariate analyses of 
relative abundance data of benthic foraminifera; each sample is assigned to a cluster 
(roman numeral as a result of the cluster analyses, and to an assemblage 
(second number in this column) as a result of the varimax factor analysis. 
Tenth column: (number of specimens) number of benthic foraminiferal specimens counted 
in each sample. 
Eleventh column: (number of species) number of species recognized in each sample. 
The numbers in the tenth and eleventh column are integers. 
Columns 12 through 42: the column headings give a speies name followed by the author 
of the species name and the year of first description of the species. 
The numbers in the columns give the relative abundance of the species (%), 
given in 1 number behind the decimal point. 
Species included are present a relative abundance of 3% or more 
in at least one sample, and an occurrence in at least 3 samples. 


Methods: The data are obtained on the larger than 150 micrometer size fraction. 
R-mode factor analysis was run on the 31 highest ranked species using the SAS/STAT package; 
the procedure is based in principal component analysis (PCA) followed by orthogonal VARMAX 
rotation. Q mode cluster naalysis was perfomed using Ward's Minimum Vrainace method; 
to standardize the data a PCA was performed on a covariance matrix of 31 species prior to 
cluster analysis. The clusters are based on a plot of semi-partial R-squared values versus
the number of clusters. 
Chronostratigraphic information: the data range in age from latest Miocene through 
Pleistocene (0.03 - 5.54 Ma). Data were generated in spring 1998.
