Nutrient chemistry of Arctic Lakes in Greenland, Norway, Russia and Alaska

Nutrient chemistry of Arctic Lakes in Greenland, Norway, Russia and Alaska
Nutrient chemistry of Arctic Lakes in Greenland, Norway, Russia and Alaska
This dataset contains nutrient chemistry data from 14 lakes in the Arctic region: 4 in Russia and Alaska and 3 in Greenland and Norway. Nutrient chemistry was measured on one occasion only at each lake, with date of collection ranging from 01/04/2011 to 14/03/2014. The following nutrients were measured: total phosphorus, soluble reactive phosphorus, total nitrogen, nitrate, ammonium, chlorophyll a, silicate, sodium, magnesium, potassium, calcium, sulphate, chloride and dissolved organic carbon. All nutrients were measured using standardised methods and the same methods were used between lake samples. The data were collected as part of the Lakes and the Arctic Carbon Cycle (LAC) project, which is funded under NERC's Arctic Research Programme.,As data were generated, checks were made to ensure linear standard curves and raw spectrophotometric readings fit within the absorbance on the standard curve. Where necessary, standard curves were adjusted accordingly. Checks were made in cases where the absorbance was below detection levels of the spectrophotometer. Calculations from quadratic equations were checked for errors before data was accepted. Water chemistry values were checked against data from previous water samples taken at the same locations.,

Abstract

This dataset contains nutrient chemistry data from 14 lakes in the Arctic region: 4 in Russia and Alaska and 3 in Greenland and Norway. Nutrient chemistry was measured on one occasion only at each lake, with date of collection ranging from 01/04/2011 to 14/03/2014. The following nutrients were measured: total phosphorus, soluble reactive phosphorus, total nitrogen, nitrate, ammonium, chlorophyll a, silicate, sodium, magnesium, potassium, calcium, sulphate, chloride and dissolved organic carbon. All nutrients were measured using standardised methods and the same methods were used between lake samples. The data were collected as part of the Lakes and the Arctic Carbon Cycle (LAC) project, which is funded under NERC's Arctic Research Programme.,As data were generated, checks were made to ensure linear standard curves and raw spectrophotometric readings fit within the absorbance on the standard curve. Where necessary, standard curves were adjusted accordingly. Checks were made in cases where the absorbance was below detection levels of the spectrophotometer. Calculations from quadratic equations were checked for errors before data was accepted. Water chemistry values were checked against data from previous water samples taken at the same locations.,
