Period length
1 year 3 months 16 days
Sampling interval
14 days Irregular Interval
Note on interval
4 occasional samples in 2022; every two weeks in 2023
Description

6 sampling points --> 3 in River Spree, 2 in Lake Müggelsee, 1 in River Erpe

2022: 4 occasional samples on 22.07., 11.08., 29.09., and 11.11.2022. Analyzed for trace organic contaminats, isotopes and anions (chloride, sulfate, nitrate)

2023: Grab samples every two weeks from mid-March to mid-November. Analyzed for trace organic contaminants, isotopes, and major ions. Temporal high-resolution EC measurements (by CTD-Divers)

 

 

Details on files:

2022_2023_WTW_isotope_major ions_trocs --> data from 2022 and 2023 from grab samples including standard water parameters (with EC measurements), stable water isotopes, major ion concentrations, and TrOC concentrations

2022_2023_water balance_Lake Müggelsee --> water components for Lake Müggelsee water balance including inflow from River Spree, evaporation, precipitation, storage change, and daily mean air temperature

2020_2023_EC_HR EC --> Occasional EC measurements at Spree Tunnel, in River Erpe and from present study from 2020 to 2023, daily mean EC from Lake Müggelsee (measured by Lake Müggelsee Monitoring station), EC measurements at inflow Lake Müggelsee, Data from Figure 3a: HR EC from 2023 recorded by CTD-Divers, Precipitation data 2023 from East Berlin

description

Man betrachtet das flüssige Wasser, das sich bei Niederschlag (Regen, Schnee, Hagel, Nebel usw.) in einer definierten Zeitspanne in einem nur nach oben offenen Gefäß mit definierter horizontaler Öffnung sammelt. Als Niederschlagsmenge bezeichnet man das Volumen der Flüssigkeit bezogen auf die Fläche der Öffnung und gibt sie an in Liter pro Quadratmeter bzw. Millimeter (1L/m² = 1mm).

Parsing data File

Estimated Time:

Why does it take so much time?

While parsing a file, the database has to perform various tasks, some of them needs a lot of CPU and memory for larger files.

  • preprocessing: means automatic detection of headlines, table body, format values or csv-separators
  • copying: means read the file cell by cell and copy all elements to the database. During this format settings can be calculated (for example iso-time)
  • analyzing: check out for different data types (can be time, numeric or text)
