The NECLIME data base in PANGAEA

All published climatic data can be included into the NECLIME data base in PANGAEA.
Therefore, we encourage everyone to contribute to this data base!
If you wish to publish your data online, please provide the published article and the properly filled Excel file NECLIME_INPUT_FORM to the data curator Christopher Traiser (christopher.traiser"at"uni-tuebingen.de).
The NECLIME_INPUT_FORM can be downloaded here!

Background: the PANGAEA data base

Information handling and knowledge management have become important backbones in Global Change research. Thus the data compiled in the course of the "Neogene Climate Evolution in Eurasia" (NECLIME) - Project are available since 2003 in the public data library "PANGAEA".
PANGAEA is part of a global information network of World Data Centres (WDCs). The information system PANGAEA is a public data library on the Internet aimed at archiving, publishing and distributing geocoded data with special emphasis on environmental, marine and geological research. The ultimate goal is the publication of data. The information system provides the relevant NECLIME data of fossil floras and palaeoclimate that are published and submitted to the data curator.

Queries in PANGAEA

A number of interfaces enable users to access meta information and analytical data. The interfaces vary in flexibility and complexity of usage, from simple search engines to complex retrieval and data processing tools. PANGAEA provides different internet clients for retrievals of stored data:

1. PangaVista allows the exploration of metadata (e.g. author, title, parameter, method, project, sampling location, principal investigator) of data sets. Keywords can be combined to create Boolean expressions, with syntax identical to that used by search engines. Results contain a short description of the retrieved datasets with the URLs to the related data included. Data can be downloaded as HTML or tab-delimited text. All data sets contain a metadata header.

2. Advanced Retrieval Tool (ART) is a data-mining tool to retrieve and download individually configured data sets. It is a web-based tool to retrieve analytical data and all types of meta information. The flexibility of this tool allows for the definition of complex retrievals as well as for the configuration and formatting of result sets, which are shown in listings and visualized as plots and or maps.

The data model of PANGAEA

The model reflects the standard processing steps for data in the natural sciences. Different institutes/projects (PROJECT) working in the earth science fields carry out expeditions (CAMPAIGN) for sampling. During an expedition at a number of locations (SITE) different samples may be taken or measurements made (EVENT). At distinct points/intervals the medium to be investigated (e.g., sediment, water or ice) is sub- sampled or measured as required (ACTIVITY). Finally, from each sample or measurement one or several analytical data values may be generated, which can be found on the 'DATA' level. These main levels are supplemented by related tables of information about staffs and institutions, gear, area, and used vehicles (Basis), literature (reference), methods, and parameters. (For NECLIME data only the structures in bold letters are relevant.)
