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 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.

These data represent phytoplankton community composition in Green Lake 4 observed during bi-weekly sampling events following ice-off starting with the 2008 field season. Samples were collected from the deepest part of the lake using a Van Dorn sampler from the surface, as well as depths of 3 and 9 m. Samples from the inlet and outlet are grab samples. Phytoplankton samples were preserved in 1% Lugol’s solution. Cell counts and biovolumes for each taxonomic group were measured using a FlowCAM. Taxonomic resolution was based on the imaging capabilities of the instrument and varies based on the size and distinguishing characteristics of the cells in a given taxonomic group. Please see details in Methods.
