Characterization of pigments in photosynthetic benthic biomass on the river bed of the Upper Clark Fork River (Montana, USA) during the algal growing season of 2020
The Upper Clark Fork River (UCFR) Long Term Research in Environmental Biology (LTREB) umbrella monitoring project generating these data is conducted separately and complementarily to the 200-million-dollar (USD) superfund project for ecological restoration of the UCFR, associated tributaries, and head water streams including Silver Bow and Warm Springs Creeks. Restoration along the UCFR in western Montana includes removal of metal-laden floodplain soils, lowering of the floodplain to its original elevation, and re-vegetation of over 70 km of the river’s floodplain closest to contaminant sources. The UCFR LTREB project includes bi-weekly water quality monitoring across the first 200 km of the river and its major tributaries along a gradient of heavy metal contamination associated with historic mining. Monitoring includes inorganic phosphorus and nitrogen concentrations, biotic standing stocks, and dissolved and whole-water heavy metal concentrations. The monitoring program began in 2017 with funding likely to be extended through 2028. The original analytical intent for data in this product was to assess the response of the river algal community to the floodplain restoration. Data are measurements of benthic biomass organic matter standing stocks and pigments associated with primary producers. Benthic biomass data were collected on the UCFR (USGS HUC 17010201) at seven monitoring sites distributed from Warm Springs (near Anaconda, MT) to Bonita (east of Missoula, MT). Data from the Deer Lodge and Garrison sites were obtained from the River Algal Succession Study, a project funded by the Montana Consortium for Research on Environmental Water Systems. Data from Bonita were obtained from the Nitrogen Fixation Algal Study, a Research Experience for Undergraduates project. Benthic samples were obtained using a cylindrical benthic sampler isolating a known area of the river bed. Five samples were obtained at each site. Estimates of organic matter in biomass were obtained fr
The European Multi Lake Survey (EMLS) dataset of physical, chemical, algal pigments and cyanotoxin parameters 2015.
The European Multi Lake Survey took place in summer 2015. It was a grassroots initiative comprised 197 scientists from 26 European countries. The EMLS was a snapshot sampling effort where 369 lakes were sampled only once for various physical (e.g. temperature), chemical (total nutrients) and biological parameters (algal pigments and toxins). The sampling period for each region was defined as the locally two-week warmest period based on 10-year air temperature data. The initial purpose was to define how nutrients and temperature would interact to explain variance in algal or cyanobacterial blooms on a continental scale using a space for time substitution approach (spatial rather than temporal resolution of lake parameters). Several other scientific questions addressing what controls toxin distribution on a continental scale, or dealing with cross comparisons between algal numerical methods (microscopy vs pigments vs flowcytometry) are in preparation. Publishing this dataset will allow scientific access to a unique sampling effort over the European peninsula that can generate new research ideas.
