Water isotope values and chemical parameters in time series samples (March 2020 - January 2021) from Müggelsee, Germany

Water isotopes (δ2H and δ18O) were analyzed in samples collected in lakes associated to major riverine systems in northeastern Germany throughout 2020. This sub-dataset is derived from water samples taken before the outflow of Müggelsee. Sampling was conducted biweekly from March 2020 to January 2021. Samples were taken with a pipette from 40-60 cm below water surface and directly transferred into a measurement vial. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water chemical and physical parameters are daily average values derived from the Müggelsee long-term data monitoring station (https://emon.igb-berlin.de/grosser_mueggelsee.html). The data give information about the seasonal isotope amplitude at Müggelsee over the studied time period.

Water isotope values in time series samples (March - October 2020) collected at buoys deployed in northeastern German lake systems

Water isotopes (δ2H and δ18O) were analyzed in samples collected in lakes associated to major riverine systems in northeastern Germany throughout 2020. This sub-dataset is derived from water samples taken at buoys temporarily installed in deep parts of the lake. Samples were taken monthly to bimonthly from March to October 2020. A Limnos water sampler was used to obtain samples from 1 m below water surface. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water temperatures were measured in similar depths with an Aqua TROLL 600 multiparameter sonde (In-Situ, Fort Collins, CO, USA). The data give information about the seasonal isotope amplitude in the sampled lakes and about spatial isotope variability in different branches of the associated riverine systems.

Water isotopes (δ2H and δ18O) were analyzed in samples collected in lakes associated to major riverine systems in northeastern Germany throughout 2020. This sub-dataset is derived from water samples taken at multiple spatially distributed spots in four selected lakes. A Limnos water sampler was used to obtain samples from 1 m below water surface on 29th and 30th September 2020. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer.

Willingmann eröffnet innovative Power-to-Heat-Anlage in Köthen

Was tun, wenn zu viel Strom im Netz ist? Bislang schalten Netzbetreiber Anlagen ab, um Überlastungen zu vermeiden. Die Köthen Energie GmbH zeigt, dass das gar nicht sein muss. Das Unternehmen hat eine neue Power-to-Heat-Anlage errichtet, die überschüssigen Strom aus erneuerbaren Energien in Wärme umwandelt und in die lokale Fernwärmeversorgung einspeist. Am heutigen Dienstag hat das Unternehmen die Anlage im Beisein von Sachen-Anhalts Energieminister Prof. Dr. Armin Willingmann offiziell in Betrieb genommen. „Das Leuchtturmprojekt hier in Köthen zeigt eindrucksvoll auf, wie mit innovativen Lösungen Engpässe im Stromnetz abgewendet werden können“, erklärte Willingmann. „Vor allem Windstrom kann hier künftig direkt in Wärme umgewandelt werden. Das ist nicht nur technisch klug, sondern auch energiepolitisch der richtige Weg. Innovative Lösungen wie hier helfen uns, Engpässe zu vermeiden und Kosten zu sparen, die sonst auf der Stromrechnung der Verbraucherinnen und Verbraucher landen. Statt Erneuerbare auszubremsen gilt es, auf Innovationen zu setzen und natürlich auch die Stromnetze weiter zügig auszubauen.“ Nach Angaben der der Köthen Energie GmbH hat der Netzbetreiber 50Hertz den Bau der Anlage mit rund 600.000 Euro finanziert und erhält im Gegenzug vollen Zugriff auf die Steuerung, um sie zur Entschärfung von Netzengpässen einsetzen zu können. Die Power-to-Heat-Anlage wird künftig Strom bis zu einer Leistung von 1,2 Megawatt aufnehmen und in Wärme umwandeln. Windkraft- und Photovoltaikanlagen können damit am Netz bleiben. Zugleich werden durch den Betrieb der Anlage weniger fossile Brennstoffe für die Wärmeversorgung benötigt, so dass auch weniger CO2-Emissionen bei der Fernwärmeversorgung anfallen. „Bundeswirtschaftsministerin Katherina Reiche sollte mal nach Köthen kommen, um sich anzuschauen, wie pragmatisch und wirtschaftlich sinnvoll die Energiewende durch Innovationen umgesetzt werden kann“, betonte Willingmann weiter. „Die Power-to-Heat-Anlage nutzt günstige Heimatenergien, steigert die Versorgungssicherheit und macht die Fernwärme wirtschaftlicher. Sie leistet darüber hinaus einen wichtigen Beitrag zum Klimaschutz.“ Impressum: Ministerium für Wissenschaft, Energie, Klimaschutz und Umwelt des Landes Sachsen-Anhalt Pressestelle Leipziger Str. 58 39112 Magdeburg Tel: +49 391 567-1950, E-Mail: PR@mwu.sachsen-anhalt.de , Facebook , Instagram , LinkedIn , Threads , Bluesky , Mastodon und X

Water isotope time series (March 2020 - March 2021) of samples collected at A. P. Møller Skolen, Kleine Breite, Schlei

Time series of stable isotopes (δ2H and δ18O) were analyzed in water samples collected near the A. P. Møller Skolen, Schleswig (Kleine Breite, Schlei), in biweekly to monthly intervals between March 2020 and March 2021. Water was sampled with a pipette from ca. 0.5 m below water surface and directly transferred into a measurement vial. Isotope analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity ring-down spectrometer. Water chemical parameters were measured in-situ with a modular WTW 3440 multiparameter devices and regularly calibrated conductivity cells (MPP 930 IDS, TetraCon® 925-P). The data give information about the seasonal isotope amplitude at the sampled locations and about spatial variability along the transects.
