Using automated overwinter sampling devices, preserved phytoplankton samples were collected from multiple depths in Lake Fryxell, a permanently ice-covered lake in southern Victoria Land, Antarctica. Photosynthetic algae (i.e. algae possessing chloroplasts) are maintained in a stable water column throughout winter darkness. The algal taxa "overwinter" in different ways, in a species specific manner. Typical vegetative cells were the most abundant form for all species found in the water column.

As part of an ongoing long-term sampling effort conducted by the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, the top 10 cm of soil was collected from sampling sites across the McMurdo Dry Valleys region of Antarctica. A subset of these samples representing each valley and a differing disturbance legacy from the last glacial maximum were analyzed for this data package. Samples were collected between 1995 and 2022.
