Archaeal tetraether lipids in sinking particles from Western tropical South Atlantic sediment trap WAB-1
No full textMicro rain radar (MRR) raw data measured at Neumayer Station (2023-07), links to files
No full textThe meteorological observatory Neumayer continuously operates a vertically looking single column 24 GHz meteorological Doppler radar (METEK MRR-PRO) to monitor hydrometeors. The instrument essentially records radar reflectivity and Doppler velocity in 128 vertical range gates. The vertical resolution is set to 50m, hence the maximal altitude is 6400m; the temporal resolution is typically 1 second. The instrument was initially installed in January 2019 and is mounted on the roof of the Neumayer Station III. Since the station altitude changes slightly over time the instrument height above sea level can change over time too. This is documented in the netCDF variable "range:meters_to_center_of_first_gate", initially 65m. Since installation an interfering signal which could not be readily identified and removed disturbs the measurements in range gates 7 to 10, i.e. 370m to 520m. The disturbance can easily be identified and filtered for analysis of the data. This dataset contains the full raw data from the instrument. All data published here is left "as recorded", no quality control was applied. Still, some concatenation and temporal re-sorting was sporadically applied to homogenise the temporal file granularity. Any such operations are documented in the netCDF global attribute "history" of the respective files

Electromagnetic induction measurements with the vertically oriented dipole of the CMD Mini Explorer (71 cm transmitter-receiver spacing) taken in June 2023 in the Lower Havel Inner Delta near Lake Gülpe, Brandenburg (Germany)
No full textElectromagnetic induction (EMI) was measured with a CMD-Mini Explorer (GF Instruments s.r.o., Brno, Czech Republic) in June 2023. We used the vertical dipole (VDP) at coil spacings of 0.32 m (VDP1), 0.71 m (VDP2) and 1.18 m (VDP3), archieving effective penetration depths of 0.5 m (VDP1), 1.0 m (VDP2) and 1.8 m (VDP3). According to the manufacturer, 70% of the signal originate from above these depths. The EMI sensors measure the apparent electrical conductivity (ECa, in mS/m). Measurements were taken by carrying the instrument about 0.2 m above ground while being directly connected to D-GPS (Leica GPS1200) for positioning. The acquisition rate was five measurements per second. Data quality was checked by measuring a reference line before and after each measurement.
The area investigated by EMI in June 2023 is located to the north and northeast of the Gülpe research station. It has a total area of 12.3 ha. The reference line was located in the southern part of the study area. No drift correction had to be applied due to good data quality. Reference lines and single outliers were removed.
The data set contains the EMI data with an intercoil spacing of 0.71 m
