The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing nutrients for the Relict Channel in the Fryxell basin. completed McMurdo Dry Valleys LTER http://mcmlter.org/ inorganic nutrients theme LTER Core Areas English ground condition 1996-01-01 2000-12-31 https://mcm.lternet.edu/sites/default/files/relcnutr.csv relcnutr eng; US McMurdo Dry Valleys LTER relcnutr Record Delimiter : \n Number of Header Lines : 1 Number of Footer Lines : 0 Orientation : Column Quote Character : "Field Delimiter : , false Dataset code Code representing stream nutrients dataset LOCATION_CODE Sampling Location Code DATE_TIME Date/time of sample (McMurdo time) Date Time Format: MM/DD/YYYY HH24:MM NO2 (mg/l) nitrite concentration determined through automated methods NO2 (MCM) (mg/l) nitrite concentration determined through manual methods NO2 (microM) nitrite concentration determined through automated methods NO2 (MCM) (microM) nitrite concentration determined through manual methods NO2 Comments Comments on nitrite measurements NO3 (mg/l) nitrate concentration determined through automated methods NO3 (MCM) (mg/l) nitrate concentration determined through manual methods NO3 (microM) nitrate concentration determined through automated methods NO3 (MCM) (microM) nitrate concentration determined through manual methods NO3 Comments Comments on nitrate measurements NO2+NO3 (mg/L) combined nitrate and nitrite concentration determined through automated methods NO2 + NO3 (MCM) (mg/l) combined nitrate and nitrite concentration determined through manual methods NO2 + NO3 (microM) combined nitrate and nitrite concentration determined through automated methods NO2 + NO3 (MCM) (microM) combined nitrate and nitrite concentration determined through manual methods NO2 + NO3 Comments Comments on combined nitrate and nitrite measurements SRP (microM) soluble reactive phosphorus concentration determined through automated methods SRP (MCM) (microM) soluble reactive phosphorus concentration determined through manual methods SRP (mg/L) soluble reactive phosphorus concentration determined through automated methods SRP (MCM) (mg/l) soluble reactive phosphorus concentration determined through manual methods SRP Comments Comments on soluble reactive phosphorus measurements NH4 (mg/L) ammonium concentration determined through automated methods NH4 (MCM) (mg/l) ammonium concentration determined through manual methods NH4 (microM) ammonium concentration determined through automated methods NH4 (MCM) (microM) ammonium concentration determined through manual methods NH4 Comments Comments on ammonium measurements DIC (mg C/L) Dissolved inorganic carbon concentration found at lake depth - mass units DIC Comments Helpful hints about the DIC sample DIN (microM) Dissolved inorganic carbon concentration found at lake depth DIN Comments Helpful hints about the DIN sample Data Source file name and/or location of data documentation Method Method / instrument used to measure nutrient concentrations DBF https://mcm.lternet.edu/sites/default/files/relcnutr.csv dataset Metadata Access Constraints: none Metadata Use Constraints: none annually McMurdo Dry Valleys LTER http://mcmlter.org/ pointOfContact
