DO - 10.3334/ORNLDAAC/196 UR - http://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=196 AB - This data set contains three ACSII files (.txt format). Two files contain above-ground biomass data for two ungrazed seashore meadow plots dominated by the saltmeadow rush Juncus gerardii at Tullgarnsnäset, near Stockholm, Sweden (approximately 59.20 N 17.50 E). There is one file for each plot. The third data file contains monthly and annual climate data from weather station near Stockholm (59.4 N 18.0 E) for the period 1951-1990. Measurements of above-ground live biomass and total dead matter were made approximately monthly by harvest methods from April 1968 to April 1969. Below-ground biomass was also measured, but the data are not reported in this data set. Annual above-ground net primary production (ANPP) was estimated by several calculation methods, including peak total live plus current dead matter; sum of species maxima (biomass + dead material); single square clippings; and variations of these equations. The rate of disappearance of dead material and mortality were also determined. Mean ANPP estimates ranged from 324 g/m2/yr (max live + dead) to 430 g/m2/yr (taken as the mean of the two sites accounting for disappearance of dead matter).
