Microzooplankton Species Found in Lake Fryxell

Abstract: 

In conjunction with the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, lakes were monitored for microzooplankton by a team based out of the University of Nottingham (led by Johanna Laybourn-Parry). This dataset shows microzooplankton species found in Lake Fryxell.

Short name:

Data sources: 

LIMNO_ZOO_1994

Methods: 

The water column in Lake Fryxell was sampled at the deepest point in the lake with a 2.21 Niskin bottle, through a hole drilled in thick ice cover (approximately 4m thick). 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). This dataset provides a list of the microzooplankton species represented in the lake water samples drawn to analyze

Maintenance: 

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.
