This dataset shows microzooplankton species found in Lake Fryxell. Name: Inigo San Gil Role: data manager completed McMurdo Dry Valleys LTER http://mcmlter.org/ unknown Data-source renamed from zplnktsp to LUMNO_ZOO_1884 to make it coherent with database in 2015   Metadata and data migrated to DEIMS.    Data for this file was submitted by Johanna Laybourn-Parry to the data manager at INSTAAR on October 21, 1998. Files were sent via e-mail as well as a hard copy. The original version of the file is stored on the Unix system in "/data1/data/lakes/plankton/laybourn-parry/Species". Upon arrival at INSTAAR, the data manager reformatted the file to present it in a relational mode. This was done using Microsoft Access. It was then exported in comma delimited ascii and MS-DOS text format to present on the web. Links to these files are provided above.   In 2006, Chris Gardner and Inigo San Gil converted the metadata to EML meeting the LTER requirements.     In 2014, with the adoption of DEIMS (inigo San Gil), metadata was enhanced, in 2016, enhanced. population dynamics theme LTER Core Areas English The Lake Fryxell basin is formed by a moraine depression in a wider portion of the Taylor Valley. It has a number of moraine islands and shallower areas, as well as several relatively well developed deltas. The lake is fed by at least 10 meltwater streams with a total drainage catchment of 230 km2. The lake is dammed to the southwest by the Canada Glacier and is topographically closed. It is perennially ice covered; during summer months, an ice-free moat generally forms around much of the lake margin. Lake levels have risen ~2 m between 1971 and 1996. There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring).

Samples were collected at 1m intervals down to 13m. Duplicate 60ml samples from each depth were fixed in buffered glutaraldehyde to a final concentration of 2% and stored in the dark at 4 degrees C prior to being analyzed for bacteria, heterotrophic nanoflagellates (HNAN) and phototrophic nanoflagellates (PNAN).
