| contents | 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. |
