Neodymium isotope gradients between ODP Sites 130-807 and 181-1123
No full textThe Neodymium isotope gradient between ODP Sites 130-807 and 181-1123 was calculated after interpolating both records at 5 kyr resolution using Acycle. NaN values indicate intervals without data. The age models follow Elderfield et al. (2012, doi:10.1126/science.1221294) and Feng et al. (2022, doi:10.1016/j.gloplacha.2022.103945)
Carbon isotope gradients between Sites ODP 130-807 and 181-1123
No full textThe stable carbon isotope (δ13C) gradient between ODP Sites 130-807 and 181-1123 was calculated after interpolating both records at 5 ka resolution using Acycle. The age models follow Elderfield et al. (2012, doi:10.1126/science.1221294) and Feng et al. (2022, doi:10.1016/j.gloplacha.2022.103945)
Aboveground plant traits along elevation gradients on disturbed and undisturbed sites in three valleys of the Central European Alps
No full textAs the European Alps are highly affected by climate change which leads to higher number of heavy rainfall events and degradation of permafrost. These changes can lead to disturbance by geomorphic processes, which can affect vegetation development. The objective of the study of Kinzner et al. (in review) was to analyse the effects of disturbance on vegetation cover and species richness and to assess the response of individual species and plant groups. We sampled, when possible, plants in plot pairs with similar topographic conditions with low distance. There we collected the five most abundant species per undisturbed and disturbed plot to measure the interspecific variability in traits as well as the three most abundant species occurring both in the undisturbed and the disturbed plot to account for the intraspecific variability. The sampled plant individuals were wrapped on site in wet paper towels and kept sealed in plastic bags. Until measurements in the laboratory they were stored in the freezer. We measured plant height, leaf dry weight, leaf area, and the SLA (specific leaf area) as they are correlated to functional strategies under geomorphic stress. The traits were measured according to Pérez-Harguindeguy et al. 2013: Plant height (cm) was measured for rosette plants as the maximum height of the rosette leaves, and for herbaceous plants as the length from the root base to the upper boundary of the photosynthetic tissue. For measuring the leaf area (mm²) three to five representative leaves from each individuum were scanned and their area was measured using the image analysis software 'ImageJ' version 1.8.0 (Schneider et al., 2012). The scanned leaves were dried at 80 °C for a minimum of 72 hours and stored at 60 °C until weighing. For weighing we used an analytical balance (Sartorius 124-1S) or in case of very low leaf weights a precision balance (Kern EG 220-3NM). Very low weighted leaves were measured five to 10 leaves together, and the mean weight was calculated afterwards. The SLA (mm²mg-1) was calculated as the ratio of leaf area and leaf dry weight
Master tracks in different resolutions of ELISABETH MANN BORGESE cruise EMB346, Rostock - Rostock, 2024-08-06 - 2024-08-20
No full textRaw data acquired by position sensors on board RV Elisabeth Mann Borgese during expedition EMB346 were processed to receive a validated master track which can be used as reference of further expedition data. During EMB346 data from the motion reference unit exail Phins Gen.3, the Trimble SPS356 GPS receiver, the Furuno GP-170 and the Furuno GP-150 GPS receiver were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track

Master track of Eugen Seibold cruise ES22C13, Playa Blanca - Playa Blanca, 2022-10-06 - 2022-10-06
No full textThis dataset contains the validated master track of the S/Y Eugen Seibold during expedition ES22C13, with a time resolution of about 10 seconds. This master track can be used as reference for further expedition data. For creating the master track, the 1-second resolution raw data acquired by the GPS position sensor on board S/Y Eugen Seibold were processed, averaging latitude and longitude within equidistant 10-second intervals. Quality control was performed visually and by checking the maximum speed calculated between neighbouring positions. In case of unrealistically high speeds, data points have been removed
Physical oceanography during RV METEOR cruise M188
No full textDuring RV Meteor cruise M188 in the eastern South Atlantic (7 March - 13 April, 2023) conductivity, temperature, and depth (CTD) measurements were made using a Sea-Bird 9plus instrument. Calibration for conductivity was performed at sea using water samples. The CTD data were processed using the standard Seabird algorithms. Downcast data were separated and averaged over 1 dbar intervals. The accuracy of the calibrated CTD measurements is: 1 dbar for pressure, 0.002 °C for temperature, 0.003 psu for salinity
