Compilation of published data from oceanic drilling that covers the late Miocene and early Pliocene interval for the study of the Late Miocene Biogenic Bloom.
Compilation of published ocean drilling (DSDP, ODP and IODP) records of sedimentation rates, CaCO3, opal and terrigenous accumulation rates that cover the late Miocene and early Pliocene interval.
We compiled oceanographic data from DSDP, ODP and IODP expeditions that cover the late Miocene and early Pliocene. Data mining was performed by automatically collecting the Pangaea datasets that correspond to the selected time interval and that have at least one of the following variables: sedimentation rate, dry bulk density, mass accumulation rate (MAR), CaCO3 accumulation rate, bSiO2 accumulation rate (biogenic SiO2) , %CaCO3, %bSiO2. The compilation was then improved by manually adding datasets absent from Pangaea but relevant to our study. The data compilation contains 154 datasets (122 are from Pangaea) from 118 different ocean drilling sites.
Age-depth models have been calibrated to the GTS2020 time scale in order to perform a temporal comparison of the datasets. This step was performed using the Neptune Sandbox Berlin database (Renaudie et al. 2020, Palaeontologia Electronica, DOI:10.26879/1032).
The Meta_Data_Table file is a metadata table with the following information : site number, dataset label, site label, publication, elevation, site coordinates, site paleocoordinates (10 Ma), available variables, variables used for labeling, the time scale used in the original publication, and the web link to the original dataset.
The Time_series file is a file that contains the time series of all the variables in all the data sets in this repository.
Each file (.csv) contains a dataset and includes the following information:
- Site number
- Original link of the dataset
- List of ages
- List of values for each variable
