Arctic LTER 1982: Biomass in tussock tundra near Toolik Lake North Slope AK (68 degrees 38N, 149derees 34W).

Abstract: 

Biomass in tussock tundra near Toolik Lake North Slope AK (68 degrees 38N, 149derees 34W). There were three harvests;Late May-early June; Late July-early August; Late August-early September. See Shaver and Chapin (Ecological Monographs, 61(1), 1991 pp.1-31.

Methods: 

Field; Samples are obtained by collecting all aboveground biomass and belowground stems and rhizomes in 20 x 20 cm quadrats, located randomly along line transects within the site. Normally, 4 or 5 quadrats are collected along each of 4 transects at each site or treatment. Aboveground biomass is considered "within" the quadrat if it is associated with a meristem that is within the quadrat. Details are given in Shaver and Chapin (Ecological Monographs, 61(1), 1991, pg. 1.)
Lab; Each quadrat is first sorted into species and then into tissue type. Depending on the harvest, tissue types can be broad categories, i.e. above and below, or more detailed, i.e. inflorescences, new growth, old growth, etc. The separated samples are dried for several days at approximately 65 ÂșC and then weighed. The dry weight for each quadrat, species and tissue type is recorded. Finally the samples from all quadrats in a transect are combined according to tissue type. Samples are then returned to Woods Hole for nutrient analysis.
This File covers three biomass harvests at the sedge site; early season, mid season, and late season.
