Abstract:
Abstract. Water stable isotopes (δ18O and δ2H) were
analyzed in samples collected in lakes, associated with riverine systems in
northeastern Germany, throughout 2020. The dataset (Aichner et al., 2021; https://doi.org/10.1594/PANGAEA.935633) is
derived from water samples collected at (a) lake shores (sampled in March and
July 2020), (b) buoys which were temporarily installed in deep parts of the
lake (sampled monthly from March to October 2020), (c) multiple spatially
distributed spots in four selected lakes (in September 2020), and (d) the outflow
of Müggelsee (sampled biweekly from March 2020 to January 2021). At
shores, water was sampled with a pipette from 40–60 cm below the water surface
and directly transferred into a measurement vial, while at buoys a Limnos
water sampler was used to obtain samples from 1 m below the surface. Isotope
analysis was conducted at IGB Berlin, using a Picarro L2130-i cavity
ring-down spectrometer, with a measurement uncertainty of 〈0.15 ‰ (δ18O) and 〈0.0 ‰ (δ2H). The data give information
about the vegetation period and the full seasonal isotope amplitude in the
sampled lakes and about spatial isotope variability in different branches of
the associated riverine systems.
