Hudson River data (Kingston, biweekly)

These are long-term data on water chemistry, water clarity, and plankton from a long-term monitoring station on the Hudson River at Kingston, New York. Most variables were measured from 1987-2015 during the ice-free season (approximately April-November). Variables include water temperature, dissolved oxygen, secchi transparency, light extinction, seston weight and organic matter content, particulate and dissolved organic carbon, turbidity, total N, ammonium and nitrate concentrations, total P, and soluble reactive phosphorus concentration, chlorophyll (=phytoplankton biomass), bacterial abundance and production, and micro- and macrozooplankton numbers.
