    Description

    Water chemistry of Lake Arendsee

    Collection of all water chemistry investigations at the lake.

    The data was collected by the Helmholtz Center for Environmental Research (Helmholtz-Zentrums für Umweltforschung, UFZ), the State Office for Flood Protection and Water Management Saxony-Anhalt (Landesbetrieb für Hochwasserschutz und Wasserwirtschaft Sachsen-Anhalt, LHW) and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB).

    carbon DOC (dissolved organic carbon)
    description

    Dissolved organic carbon (DOC), sometimes known as dissolved organic material (DOM),[1] is a broad classification for organic molecules of varied origin and composition within aquatic systems. The "dissolved" fraction of organic carbon is an operational classification. Many researchers use the term "dissolved" for compounds below 0.45 micrometers, but 0.22 micrometers is also common, saving colloidal for higher concentrations. A practical definition of dissolved typically used in marine chemistry is all substances that pass through a GF/F filter. The recommended measure technique is the HTCO technique after filtration on precombusted glass fiber filters, typically GF/F filters.[2]

    Dissolved organic carbon in marine and freshwater systems is one of the greatest cycled reservoirs of organic matter on Earth, accounting for the same amount of carbon as the atmosphere and up to 20% of all organic carbon.[3] The source of dissolved organic carbon depends on the body of water. In general, organic carbon compounds are a result of decomposition processes from dead organic matter such as plants or marine organisms. When water originates from land areas with a high proportion of organic soils, these components can drain into rivers and lakes as dissolved organic carbon.

    Dissolved organic carbon is also extremely important in the transport of metals in aquatic systems. Metals form extremely strong complexes with dissolved organic carbon, enhancing metal solubility while also reducing metal bioavailability.

    name
    carbon TIC (total inorganic carbon)
    description

    The total inorganic carbon (CT, or TIC) or dissolved inorganic carbon (DIC) is the sum of inorganic carbon species in a solution. The inorganic carbon species include carbon dioxide, carbonic acid, bicarbonate anion, and carbonate.[1] It is customary to express carbon dioxide and carbonic acid simultaneously as CO2* . CT is a key parameter when making measurements related to the pH of natural aqueous systems,[2] and carbon dioxide flux estimates.

    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)
