Aquatic Macroalgae Collection (Chemical Preservation [Clip Harvests]) (NEON-AMAC-CPCH)

This collection contains subsamples of aquatic macroalgae from clip harvest samples (NEON sample class: apl_domainLab_in.sampleIDmacroalgae). Aquatic macroalgae clip harvest sampling is conducted once per year at wadeable streams, lakes, and river (during the mid-summer aquatic biology window). During the first and third bouts in rivers and lakes, only presence/absence of vegetation is noted; during the mid-summer bout, samples are collected via quadrats in wadeable streams, and rake collection in lakes and rivers. Ten samples are collected per site if plants are present. In wadeable streams, clip harvest samples are collected near plant transect locations. In lakes and rivers, ten randomly selected points are sampled at depths that are colonized by plants. Aquatic macroalgae vouchers are preserved in 2% glutaraldehyde. Vouchers are stored in a temperature (17-18°C) and humidity controlled environment. See related links below for protocols and NEON related data products.
