Overview
Browse more than 500 pages of
images and information about
inland diatoms (mainly freshwater)
from the McMurdo
Dry Valleys region
- View images to assist diatom identification.
- Browse taxon information such as length, width, original type description, and references.
- Search samples to see what taxa are present in stream algal mats, sediment cores, and water samples.
- Browse waterbody information such as location, setting, map, and photos.
- View individual diatom counts to check relative abundances in different settings.
This site is part of an ongoing effort to discriminate between Antarctic species that are relatively recent invaders from those that are relicts of a warmer past.
We are considering including diatom samples from other parts of Antarctica in the future.

Taylor Valley. View to the east through one of the Dry Valleys. The Kukri Hills dominate the right side of the picture. McMurdo Sound and Mt. Erebus (uppermost right) are visible in the background. Near the coast and extending into the valley is Commonwealth Glacier (upper left), with Lake Fryxell bracketed between Commonwealth and Canada glaciers.
