Index of Chlorophyll files

Index of LTER lakes Chlorophyll files

Chlorophyll and Primary Production:

One file for each lake each year data was collected Files contain date, depth and chl a ug/l, and mg C/m^3 /d. The third fourth and fifth letters in all file names of Chlorophyll a and Primary productivity data files are the lake names. The last two or three letters are eitherchl or ch.

  • 7588tlkc - Chlorophyll A, and primary productivity of Toolik lake 1975 - 1988. Water samples were taken weekly from Toolik lake. The sampling depths for the Control side were 0, 1, 3, 5, and 6 meters and the Treatment side were 0, 1, 3, 5, and 7 meters

  • 8588n2cc - Chlorophyll A, and primary productivity of lake N-2 reference for 1985, 1986, 1987, 1988. Water samples were taken weekly from both sides of lake N-2. The sampling depths for the Control side were 0, 1, 3, 5, and 6 meters and the Treatment side were 0, 1, 3, 5, and 7 meters

  • 8588n2fc - Chlorophyll A, and primary productivity of lake N-2 treatment for 1985, 1986, 1987, 1988 , Arctic LTER 1985 to 1988.

  • ARC_Lakes_PrimProdChl_1983-1989 - Decadal file describing the chlorophyll a and primary production in various lakes near Toolik Research Station (68 38'N, 149 36'W) during summers from 1983 to 1989. Sample site descriptors include an assigned number (sortchem), site, date of analysis (incubation), time, depth and rates of primary production. The amount of chlorophyll a and pheophytin were also measured.

Sample site descriptors include an assigned number (sortchem), site, date of analysis (incubation), time, depth and rates of primary production. The amount of chlorophyll a and pheophytin were also measured.

  • ARC_Lakes_PrimProdChl_2010-2014 - Decadal file describing the chlorophyll a and primary production in various lakes near Toolik Research Station (68 38'N, 149 36'W) during summers from 2010 to 2014. Sample site descriptors include an assigned number (sortchem), site, date of analysis (incubation), time, depth and rates of primary production. The amount of chlorophyll a and pheophytin were also measured.
