Seabed photographs taken along OFOBS profile PS126_3-21 during POLARSTERN cruise PS126
No full textDuring the RV POLARSTERN cruise PS126 (2021-05-24 to 2021-06-27) to the long-term ecological research station HAUSGARTEN observatory in the Fram Strait the Ocean Floor Observation and Bathymetry System (OFOBS) was used to collect still images from various locations surveyed during the expedition. The OFOBS consisted of a towed underwater camera system equipped with a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III). The camera was mounted on a steel frame (140 L x 92 W x 135 H cm), together with two strobe lights, three laser pointers spaced with a distance of 50 cm used to estimate the size of seafloor structures, four LED lights, and a USBL positioning system (Posidonia). An automatic seafloor image was taken every 20 seconds to obtain 'TIMER' stills distributed at regular distances along each of the survey profiles. Additional 'SW_RELEASER' photos were triggered individually when interesting objects appeared in the live feed. During this expedition, no positioning data was available for the OFOBS. Here, image data of OFOBS deployment PS126_3-21 is presented
(Bio)geochemical data Pürgschachen Moor
No full textThe dataset contains multi-proxy-analyses (element geochemistry, stable Pb isotopes, humification index, ash content) of a 500-cm-long, 14C dated peat core covering the past ~5000 years from the ombrotrophic Pürgschachen Moor in the Styrian Enns Valley (Austrian Alps)
Permittivity measured with the dielectric profiling (DEP) technique on the Talos Dome ice core, Antarctica
No full textDielectric Profiling (DEP) of the Talos Dome Ice Core (TALDICE) were recorded in the field during the 2005-2007 field seasons with the DEP device described by Wilhelms et al. (1998). The permittivity and conductivity of DEP data are calculated by their respective densities and conductivities (Wilhelms, 2005). The resolution of DEP data is 5 mm depth intervals. The DEP was not processed at a consistent temperature due to the varying temperature in the field seasons. For more information on the calibration procedure see Mojtabavi et al, 2020

Effects of drought on generation 2 Lupinus bicolor (Fabaceae)
No full textData are for Lupinus bicolor grown in a dry-down drought experiment at UC Santa Barbara in a second (F1) generation to test for maternal effects on plant growth and reproductive output. Plants were grown in dry-down and well-watered conditions in order to simulate potential maternal effects. Data collected include seed production, vegetative and phenological traits. The seeds were collected by hand between 2016-12-01 and 2017-02-28 near UC Santa Barbara Greenhouses. The greenhouse had climate controlled conditions with an average temperature of 21.1°C – 22.2°C
