Data Usage Summary
  • Data Use Policy

    1. Use our data freely. All Niwot LTER data products (except some recent data sets for which metadata but not data are available) are released to the public and may be freely copied, distributed, edited, remixed, and built upon under the condition that you provide acknowledgement as described below.

    2. Give proper acknowledgement. Publications, models and data products that make use of these data sets must include proper acknowledgement, including citing data sets in a similar way to citing a journal article. See http://www.datacite.org/whycitedata). The following acknowledgment should accompany any publication or citation of these data: Logistical support and/or data were provided by the NSF supported Niwot Ridge Long-Term Ecological Research project and the University of Colorado Mountain Research Station

    3. Let us know how you will use the data. The data set creators and Niwot LTER would appreciate hearing of any plans to use the data set. Consider consultation or collaboration with data set creators.

    4. Although efforts have been made to ensure that these data are of the highest quality, the possibility of errors exists. Plase notify the data manager of any errors at lternwt@colorado.edu.

Abstract:

This dataset contains water quality measurements made on Green Lakes 1, 4, 5, and Lake Albion starting in 2000 (for Green Lake 4) and ongoing. Water samples were collected for analysis of chlorophyll a, pH, temperature, specific conductivity, dissolved oxygen (dO), % saturation, secchi depth, light attenuation, and % of surface. Most samples were collected between 0900 and 1100 MST. The first sampling date each summer occurred shortly after the ice had melted. An inflatable raft was used to reach the middle of the lake. The majority of the measurements were taken at the surface, three meters, and nine meters from the raft. However, additional measurements were taken for side projects of the long-term dataset during several of the years and are included in this dataset. Water samples were collected using a Van Dorne sampler. Field measurements were conducted using a YSI dissolved oxygen meter and a Li-Cor datalogger. Chlorophyll was extracted from filtered samples and absorbance was measured before and after acidification to quantify chlorophyll a concentration.
