Total organic carbon, biogenic silica concentrations, total nitrogen concentrations and carbon nitrogen ratios in short sediment core from Lake 850, Sweden

Total organic carbon (TOC), biogenic silica (BSi) concentrations, total nitrogen (TN) concentrations and carbon nitrogen ratios (C/N) from short sediment core, which was taken in March 2019 from ice-covered lake are presented.The sediment core analyzes of TOC, TN and C/N were measured on 5 to 10 mg of freeze-dried sediment using elemental analyzer COSTECH ECS4010. The biogenic silica concentrations were determined using weak alkaline extraction by Conley and Schelske (2001) using 30mg of freeze-dried sediment reacting with 40ml of 0.1M Na2CO3 for 5 hours. The DSi concentration in the extracted aliqote was measured using molybdate blue method (Strickland and Parsons, 1972) using Smartchem 200, AMS System descrete analyzer.
