Data sets
(Expand by double-clicking on the archive icon und then by using the extract command in WinZip 11.1).
Explanations for the C. leptoporus data-set, in subdirectory [CLEPTOP]:
Subdirectory [MEASURES/DIAM_EL] contains the original bivariate measurements of coccolith diameter (in µm) versus the number of elements, separated by a comma. Each file represents a sample. The data are sorted into core locations. Holocene surface sediment samples are sorted into folder [HOLOCENE]. For the provenance of Holocene materials refer to Knappertsbusch et al. (1997), for the provenances and ages of the remaining material refer to Knappertsbusch (2000). Open files with MS Word to watch the formatting.
Subdirectory [GRIDDED] contains absolute frequencies (number of coccoliths per grid-cell) per sample per core using a grid-cell size of 1µm in length and 2 elements in width. The gridded data for C. leptoporus were calculated using program Grid2 from the binary measurements of diameter versus number of elements in the distal shield in each sample and are from Knappertsbusch (2000). Open files with MS Word to watch the formatting.
Subdirectory [INP_VOX] contains the coccolith frequency data (ALL_XYZFsn) arranged by core after application of the Grid_toVox4 program was performed. File ALL_XYZFsn can be directly imported to Voxler. X denotes the diameter in µm, Y the number of elements in the distal shield, and Z indicates the coccolith frequency per grid-cell. During running of Program Grid_to_Vox4, the options "with scaling of axes and with normalization of Frequency (option 1)" and "output to one single file (option 1)" were applied. The common age to all cores (ZMAX) was 23.08 Ma.
The lowercase letter "s" of the filename ALL_XYZFsn indicates, that all axes were standardized to units between 0 and 1, whereas the lowercase letter "n" indicates, that the coccolith frequencies were normalized by conversion from absolute to relative frequencies. Open files with MS Word to watch the formatting.
The MS Word file "statistics" in folder [AGES] reproduces a survey of samples, numerical ages, and statistical data for all C. leptoporus data, as they were published in Knappertsbusch (2000) and used in the present study for construction of volume density plots.
Explanations for the G. menardii data-set, in subdirectory [GMENAR]:
Subdirectory [MEASURES] contains the split-weighted morphometric measurements of G. menardii from DSDP Sites 502A and 503A, arranged per sample (see Knappertsbusch, 2007). In "composed_files" all measurements are merged together into one single file. The format of the header line of "composed_files" applies also to the individual sample files. For collecting bivariate measurements of spiral height versus axial length cited in the paper, the respective columns (X,Y) must be extracted before they can be fed to the gridding program. Open files with MS Word or MS Excel to watch the formatting.
Subdirectory [GRIDDED] contains absolute frequencies (number specimens per grid-cell) per sample for the DSDP Sites 502 and 503. Also for these data program Grid2 was applied to bivariate measurements of X (spiral height, in µm) versus Y (axial length, in µm) using a grid-cell size of 100 µm in length and 50 µm in width as was discussed in Knappertsbusch (2007). The subdirectory [XY data] provides the bivariate measurements of X versus Y for each sample; the filenames encode for the absolute age (in million years), the ages were taken from the study of Knappertsbusch (2007). Open files with MS Word or MS Excel to watch the formatting.
Subdirectory [INP_VOX] contains the files "ALL_XYZFsn_ZMAX=8Ma", that were obtained with
Grid_to_Vox3 on the respective lists of gridded data files from DSDP Sites 502 and 503.
Open files with MS Word or MS Excel to watch the formatting.
Parameters for Gridding in Grid2.2:
Data range: 0-700µm, 0-1600µm,
Grid-cell size: DeltaX = 50µm, DeltaY = 100µm.
The files ALL_XYZFsn_ZMAX=8Ma (same name for DSDP Sites 502 and 503) can directly be imported to the spreadsheet from Voxler.
Parameters set in Program Grid_to_Vox3:
Option "with scaling of axes and with normalization of Frequency" (Option 1)
Option "output to one single file (option 1)"
In file "ALL_XYZFsn_ZMAX=8Ma" the axes were standardized to units ranging from 0 to 1 (indicated by the lowercase letter "s" in the filename) and frequencies F of specimens per grid-cell are normalized to relative values ranging from 0 to 100% (indicated by the lowercase letter "n" in the filename) in order to maintain inter-sample comparison.
The common age to all cores (ZMAX) was set to 8.0 Ma.
Tutorial – Program Grid_to_Vox
Given are bivariate (X,Y) scatter data from a series of samples at different geological ages. Using program Grid2.2.out discrete bivariate frequency distributions Delta X, Delta Y,Z,F are generated, with Delta X and Delta Y being the grid-cell sizes of the X- and Y coordinate axes, respectively, with Z being the geological age of a particular sample, and with F being the bivariate frequency of points per grid-cell (see, for example, Knappertsbusch, 2000). The program Grid_to_Vox3 is reserved for handling the G. menardii data set, while Grid_to_Vox4 is reserved for the C. leptoporus data set (this separation into two programs was done in order to keep computer programs as simple as possible).
Input to Grid_to_Vox:
Both Grid_to_Vox versions work in batch operating mode, so that a large number of gridded input files can be processed one after the other. Two types of input files are required: First, one text file called List_of_files, which contains a list of the age (in Ma) of the sample and the corresponding name of the file with the gridded data matrix per sample. The gridded data matrix contains the frequency distribution of the bivariate set of measurements. The age must be written in digits of five characters, followed by a comma, followed by the name of the gridded input matrix. The name of the gidded input data is 16 characters long. The second type of input files are the files with the gridded data matrices (one file per sample). The gridded data matrices need to be unformatted, i.e., without any header or column information (these must first be removed by manual editing).
Example for Grid_to_Vox3 (Globorotalia menardii):
File List_of_files:
00.340,input1xxxxxxxxxx_grd.txt
56.781,input2xxxxxxxxxx_grd.txt
Gridded data matrix (for Globorotalia menardii):
A 14x16 matrix (14 columns, 16 rows).
Delta X goes in horizontal direction (mid-points at 25, 75, 125,..., 675 micrometers).
[Intervals of Delta X=50micrometers].
Delta Y goes in vertical direction (mid-points at 50, 150, 250,...,1550 micrometers).
[Intervals of Delta Y=100 micrometers].
