Introduction to diatoms
An introduction to diatoms is available from the microfossil image recovery and circulation for learning website supported by University College London
Antarctica
McMurdo Dry Valleys Long-Term Ecological Research (MCM LTER)
MCM LTER is an interdisciplinary study of the aquatic and terrestrial ecosystems in a cold desert region of Antarctica. In 1992 the McMurdo Dry Valleys area was selected as a study site within the National Science Foundation's Long-term Ecological Research (LTER) Program.

Taxonomy & references
Index Nominum Algarum (INA)
The INA is a card file containing bibliographic references pertaining to algal taxonomy. It contains nearly 200,000 names of algae (in the broad sense) and is maintained by Paul Silva at the Herbarium of the University of California.
Index Nominum Genericorum (ING)
The ING attempts to bring all generic names of plants together in a single list to reveal homonymy between groups. In addition, ING includes bibliographic citations and information about the typification and nomenclatural status of generic names It is maintained by the U.S. National Herbarium, Department of Botany, Smithsonian Institution
Diatom databases
ANSP Algae Image Database
This database contains light micrograph images of diatom taxa from rivers throughout the USA. The images were made primarily by ANSP Patrick Center Phycology Section staff as part of their routine analysis of algal samples.
Cal Academy Hanna Database
The Hanna Database provides taxon, locality, and publication information for tens of thousands of samples from sites all over the world. The database also contains thousands of bibliographic references. It is portion of the California Academy of Sciences Diatom Collection.
Diatom Paleolimnology Data Cooperative
The DPDC is a database of diatom and associated ecological and paleolimnological data relevant to study of long-term trends in variables related to global change. It contains data from western hemisphere lakes, wetlands, or estuaries and includes regional surface-sample calibration sets, sediment cores, and other types of samples. It is supported by several groups including the Phycology Section, Patrick Center for Environmental Research and NOAA Paleoclimatology.
