Aquatic Macroalgae Collection (Chemical Preservation [Point Counts]) (NEON-AMAC-CPPC)

This collection contains subsamples of aquatic macroalgae collected during point counts (NEON sample class: apc_perTaxon_in.sampleIDmacroalgae, apc_voucher_in.sampleIDmacroalgae). Aquatic macroalgae point count data are collected three times per year at wadeable streams only, during aquatic biology bout windows, roughly in spring, summer, and fall. Data are collected at ten permanent transect locations that are revisited during each sampling bout. Aquatic macroalgae vouchers are preserved in 2% glutaraldehyde and stored in a temperature (17-18°C) and humidity controlled environment. See related links below for protocols and NEON related data products.
