File List 25692_2_data_set_270203_lfqr22.csv -- (MD5: 172a372a325f89b9fc2f54e5222996ee) Description Data was created in an Excel file, and saved as a comma-delimited ASCII file, 25692_2_data_set_270203_lfqr22.cvs. The first two rows are the headings. The next 156 rows are the monthly data, inclusive from January 1994 through December 2006. The last row contains checksum values for download verification. Blank values are denoted by “99999”. The column headings contain variables under the five main variables of Date, Lake, Brine Shrimp, Phytoplankton, and Other Biota. The column variables are described below for each main variable. Date includes 2 columns: Month, Year Lake includes 10 columns: Lake Elevation (m), Lake Volume (m^3), Salinity (%), Temperature (C), Dissolved Oxygen (% saturation), Nitrogen (at 1-4m)(mg/L), Nitrogen (at 4+m)(mg/L), Phosphorus (at 1-4m)(mg/L), Phosphorus (at 4+m)(mg/L), Secchi Depth (m) Phytoplankton includes 5 columns: Chlorophyll_a (ug/L), Chlorophytes (ug/L), Bacillariophytes (ug/L), Cyanophytes (ug/L), Maximum Chlorophyll_a (ug/L) Brine Shrimp includes 9 columns: Cysts (#/l), Nauplii (#/l), Juveniles (#/l), Males (#/l), Barren Females (#/l), Females w/ Eggs (#/l), Females w Cysts (#/l), Biomass (Adult Equivalent), Cyst Harvest (metric tons) Other Biota includes 6 columns: Corixids (#/m^3), Grebes (total #), Protozoans (#/mL), Dinoflagellates (#/mL), Copepods (#/m^3), Brine Flies (#/m^3) CHECKSUM: Month = none, just the label “CHECKSUM”; Year = 312,000; Lake Elevation = 199,662.90; Lake Volume = 1.70318E+12; Salinity = 1749.78; Temperature = 1894.38; DO = 2726.42; N shallow = 26.5058; N deep = 136.5385; Phosphorus shallow = 11.5075; Phosphorus deep = 18.9285; Secchi Depth = 240.15; Chlorophyll_a = 3720.928; Chlorophytes = 456.9437018; Bacillariophytes = 970.5399242; Cyanophytes = 794.072427; Max Chl_a = 8768.07; Cysts = 5563.054425; Nauplii = 623.6800176; Juveniles = 189.6569998; Males = 76.53309394; Barren Females = 61.05721909; Females w/ Eggs = 4.4904062; Females w/ Cysts = 8.699123133; Biomass = 349.5981; Cyst Harvest = 63,822.92; Corixids = 36.8290032; Grebes = 118,887,480; Protozoans = 30,379.52; Dinoflagellates = 38,740.21; Copepods = 2309.11; Brine Flies = 361.400003
