title: Total organic carbon (TOC) concentration from drillhole FB2001 located in Messel (Darmstadt)

description: We analyzed 10 samples from the FB2001 depth interval 10-9 m for their Total Organic Carbon (TOC) content. This new data set is supplementary to the existing TOC record of Bauersachs et al. (2014) for the depth interval 145-1 m of the same core. The new samples were measured due to low spatial resolution of the existing TOC data set (~two samples per meter; Bauersachs et al., 2014; doi:10.1016/j.palaeo.2014.06.015) relative to the gamma-ray data (~10 data points per meter), and thus allow for a same-resolution assessment of the gamma-ray/TOC relationship. For the TOC measurements we followed the protocol of Bauersachs et al. (2014). In short, the dried and powdered sediment samples (ca. 30 mg) were pretreated with excess 2M hydrochloric acid (HCl) to remove carbonates, neutralized with distilled water, and again dried at 50 °C for 24 h. Subsequently, samples were measured in duplicates using a CS-Analyser 144DR (Leco Coopeation) at the Institute of Earth Sciences at Heidelberg University with a sample reproducibility of &lt; 0.5%.

title: Total organic carbon (TOC) and δ13CTOC measurement from drillhole FB2001 located in Messel (Darmstadt)

description: The methodology for total organic carbon (TOC) and δ13CTOC measurement followed Bauersachs et al. (2014, doi:10.1016/j.palaeo.2014.06.015). In brief, for TOC concentrations, sediment samples (approximately 30 mg) were dried and powdered, pretreated with excess 2M hydrochloric acid (HCl) to eliminate carbonates, neutralized with distilled water, and dried at 50°C for 24 hours. Subsequently, samples were analyzed in duplicates using a CS-Analyser 144DR (Leco Corporation) at the Institute of Earth Sciences at Heidelberg University, with a sample reproducibility of less than 0.5%. For δ13C analysis, portions of the powdered, decalcified sediment samples (1-2 mg) were examined using a Flash Elemental Analyzer 1112 (Thermo Scientific), connected to the continuous flow inlet system of a MAT 253 gas source mass spectrometer (Thermo Scientific) at the Institute of Geosciences, Goethe University Frankfurt. Carbon isotopes in graphite standard USGS24 were analyzed alongside the samples to ensure accuracy and precision. Isotope ratios are expressed in conventional delta notation: δsample (‰) = [(Rsample − Rstandard) / Rstandard - 1] × 1000, where R represents the ratio of 13C/12C of the sample and the standard Vienna Pee Dee Belemnite (VPDB). Accuracy and precision of all isotopic analyses were determined by replicate sample analysis, yielding pooled standard errors better than 0.2 ‰ for δ13CTOC.

title: Gammy ray measurements from drillhole FB2001 located in Messel (Darmstadt)

description: The regularly spaced downhole gamma-ray log data (vertical sample rate = 0.1 m) from FB2001 located in Messel (Darmstadt) for the depth interval between 190 m to 1 m were already published in Felder and Harms (2004) and Wonik (2005). The gamma ray logging was done using a spectral gamma ray sensor (ANTARES). The normalized borehole gamma ray logging data from drill hole FB2001 was employed for astronomical tuning against the reference astronomical solution La2010d (Laskar et al., 2011, doi:10.1051/0004-6361/201116836).

title: Standardized mineral data of sediment core PG1746 from Lake Temje (Yakutia, Russia)

description: This data set is part of a larger data harmonization effort to make lake sediment core data machine readable and comparable. Here we standardized mineral data (Quartz and Calcite) of sediment core PG1746 from Lake Temje (Yakutia, Russia). Lake Temje (62°03′ N, 129°29′ E) is a thermokarst lake located 13 km east of Yakutsk on the Magane Terrace, west of the Lena River at ca. 208 m a.s.l. The lake is shallow, with a maximum depth of 75 cm and no permanent inflows and outflows. The 3.8 m lake sediment core PG1746 was recovered as part of a joint Russian-German expedition of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI, Germany, Potsdam) in cooperation with the North Eastern Federal State University (NEFU, Russia, Yakutsk) to Yakutia in July 2004. Sampling was performed from two connected rubber boats in the central part of Lake Temje at 70 cm water depth with a rod-operated half-tube corer (Russian peat corer: 5 cm in diameter, 100 cm long sampler). Overlapping core sections yielded a 380-cm-long sediment-core sequence. The core sections were described and sampled at 5-cm intervals in the field. X-ray diffraction analysis (XRD) was conducted to check both the presence of carbonate and the mineralogical composition of carbonate, which solely consists of calcite (XRD peak at 3.027 Å). The XRD data were also used to check the relative amount of quartz (XRD peak at 3.34 Å). XRD measurements were undertaken on random powder mounts, using a Philips PW1820 goniometer at AWI Bremerhaven (40 kV, 40 mA, from 3 to 100 , step-rate 0.05 , Co kα radiation).

Overlapping core sections yielded a 380-cm-long sediment-core sequence. The core sections were described and sampled at 5-cm intervals in the field. One set of subsamples were weighted in wet condition, freeze-dried, and weighed again to estimate the water contents. Weight concentrations in total organic carbon (TOC), total carbon (TC), and total nitrogen (TN) contents have been estimated chromatographically on milled samples, using a Vario™ CNS Elementanalyser. The data were used to calculate the TOC/TN ratio, using a factor of 1.167 to obtain the atomic ratio. Calcium carbonate weight concentrations were calculated from the inorganic carbon contents, the difference between TC and TOC, multiplied by a factor of 8.33 to include the stoichiometric contributions from calcium and oxygen. Inorganic carbon concentrations were below the limit of detection in the middle and upper parts of the sediment core.

title: Dive metrics of sperm whales collected between 2017 and 2019 off the Azores, Portugal

description: The development of sophisticated multi-sensor tags incorporating high-resolution movement sensors and hydrophones has enabled unprecedented views of the 3D fine-scale movement behaviour of cetaceans, especially for those species that use sound to forage. However, these tags are expensive, making them inaccessible to most researchers. Time-Depth Recorders (TDRs), which have been widely used to study diving and foraging behaviour of marine mammals, offer a more affordable alternative. Unfortunately, data collected by TDRs are bi-dimensional (time and depth only), so quantifying foraging effort from those data is challenging.Pérez-Jorge et al. (2023) developed a predictive model of prey capture attempts (PCAs) for sperm whales from low-resolution time-depth data. To develop this model, high-resolution movement and acoustic data from 12 sperm whales instrumented with digital acoustic recording tags (Dtags; Johnson et al., 2003; Oliveira et al., 2022) between 2017 and 2019 in the Azores archipelago, Portugal. This data was used to extract time-depth values at a sampling frequency of 1 second (typical sampling rate of low-resolution time-depth data) and detect buzzes, considered to represent PCAs. Based on the extracted time-depth values, a suite of dive metrics (ie., average depth, variance of depth) were obtained for different segment durations (30 seconds, 60 s, 180 s and 300 s). The present dataset includes the extracted dive metrics for the four segment durations selected on the final model of the study (Pérez-Jorge et al., 2023).Data provided for each record include the event number, individual identification, dive identification, date of sampling, latitude, longitude, dive phase, segment duration, number of buzzes, average of water depth per segment, variance of water depth per segment and variance of velocity.
