Circumpolar Diatom Database (CDD): a new database for use in paleolimnology and limnology

Abstract

The Circumpolar Diatom Database (CDD) is a new, open-access, online resource for the analysis of species distribution and abundance of diatoms in high-latitude, circumpolar regions. We provide a short description of the CDD design and its components and the data consultation methods and procedures, to familiarize potential users with the project and the database. In addition, opportunities for data exchange and input are described, to allow optimal application and expansion of the CDD by the user community, composed of paleolimnologists, limnologists and northern researchers in related disciplines.
