Macroinvertebrates from Rivers in Northwest Alaska, 2015-2019 This dataset contains taxonomic information, counts, and lengths of macroinvertebrates collected from rivers in northwest Alaska using drift and kick nets during summer and fall 2015-2019.

Chemical analyses were performed for hydrochemical parameters including field parameters, major ions, nutrients, metals, stable isotopes of water, and tritium, as well as for dissolved gases useful for determining the timescale over which the water was in the subsurface (i.e. age dating tracers), including noble gases and chlorofluorocarbons.

Macroinvertebrates were collected using kicknets and driftnets in April and August with the goal of comparing populations to those sampled from the same water bodies by the USGS in the 1970s.
