Constituent Databases

Neotoma is a database of databases. While some data is stored in “Neotoma”, most data is associated with a particular constituent database, organized around a proxy type and also often a geographic region or time period.

Currently not complete. Pulling from rough data within Craft as a sample.

The Academy of Natural Sciences of Drexel University (ANSDU) constituent diatom database was established in 2010 with funding from a 2009 National Science Foundation grant to establish Neotoma. It continued work assembling data that had been ongoing as part of the Diatom Paleoecology Data Cooperative, funded by NOAA and NSF from 1994- 2008. The ANSDU database extends data from sites that were initially in the DPDC, and adds many additional new sites and datasets. It contains primarily diatom count data for lake surface samples and sediment cores. ANSDU data are contained entirely within Neotoma. There is no separate database or website, though there is a directory at Drexel University with contributed data files and supporting materials.

The APD was first developed in 1996. The initial workshop and subsequent work, funded by the French CNRS, the EU (INCO, ENRICH) and UNESCO (PICG), established methods of collating pollen data, developed a standardized pollen nomenclature (Vincens et al. 2007), generated updated age models, collated images of pollen grains, and created a searchable web interface. Due to a lack of funding and the closure of the French data center, Medias-France, the APD lapsed in 2007, making its extant data holdings largely inaccessible and leaving no home for newer paleoecological records. It has recently been revived and various contributors are actively adding data to the database.

The main types of data included in the DPDC are site information, diatom counts, water chemistry and other environmental data, and chronologies. The DPDC was initially funded by NOAA and NSF from 1994 - 2008, with continued support to facilitate transfer to Neotoma coming from NSF. For more information and history, see the DPDC website. Data that were originally included in the DPDC via the linked website have been accessible to retrieve since 2021, thus the DPDC constituent database within Neotoma is the primary source of data currently.

Data downloaded from this constituent database should be cited, as well as the original source publications and investigators whenever possible. Please use the following as an example: “Data were obtained from the Diatom Paleolimnology Data Cooperative (https://diatom.ansp.org/dpdc/), a constituent database of the Neotoma Paleoecology Database (https://www.neotomadb.org/). The work of data contributors, data stewards, and the Neotoma and DPDC communities is gratefully acknowledged.”
