title: Survival of recovering F2 adults following parental (F1) exposure to the isolated and combined effects of hypoxia and marine heatwave events in the calanoid marine copepod Acartia tonsa

description: Specimens (F1) of the marine calanoid copepod Acartia tonsa were exposed for five days under laboratory conditions to the isolated or combined effects of hypoxia and a marine heatwave. Then, their offspring (F2) were returned to control conditions (C: 18 °C, 100 % O₂ sat.) for the rest of their life cycle to simulate a recovery period. This dataset compiles the survival data, expressed in terms of percentage and as the number of individuals at the beginning and end of exposure, of recovering F2 adults following parental exposure to the isolated and combined effects of hypoxia and a marine heatwave.
description: The experiment was conducted in the Marine Ecological and Evolutionary Physiology Laboratory (MEEP) at the University of Quebec in Rimouski (UQAR), Rimouski, QC, Canada. Copepods of the species Acartia tonsa were maintained following the stock culture culturing protocol described in Dam et al. 2021 (https://doi.org/10.1038/s41558-021-01131-5). Namely, copepods were kept in three 5 L aquaria filled with artificial seawater kept at a salinity of 28.4 ± 0.5. The physicochemical parameters of the seawater were the following: temperature of 18 ± 0.4 °C, oxygen saturation of 93.7 ± 6.0 %, and pH NBS of 8.20 ± 0.09 before the experiment. The photoperiod was kept at 13h light: 11 h dark. Copepods were fed ad libitum with a mixture of three phytoplankters: Tetraselmis sp., Thalassiosira weissflogii and Rhodomonas salina. Parents (F1) were transferred in 2 L aquaria placed in an experimental system during the 5-d exposure to the isolated and combined effects of hypoxia and MHW conditions. Once the parents (F1) were removed, their offspring (F2) were kept in the same 2 L aquaria and exposed to the control condition to simulate a recovery period until they reached sexual maturity. All traits were measured on F2 adult individuals. For all F1 traits measured during the exposure phase, please refer to the following database: https://doi.pangaea.de/10.1594/PANGAEA.967352.---This study was additionally supported by the FIR UQAR grant of the Université du Québec à Rimouski.

title: ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM107

description: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM107 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode with 8 m bins and a blanking distance of 8.0 m, while 100 bins were recorded using a pulse of 1.42 s. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). Heading, pitch and roll data from the ship's gyro platforms and the navigation data were used by the data acquisition software VmDas internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and the ship's heading data. Further errors stem from a misalignment of the transducer with the ship's centerline.Data post-processing included water track calibration of the misalignment angle (0.61° +/- 0.8098°) and scale factor (0.9987 +/- 0.0117) of the Ocean Surveyor signal. The average interval was set to 60 s. Velocity quality flagging is based on following threshold criteria: abs(UC) or abs(VC) &gt; 1.5 m/s, rms(UC_z) or rms(VC_z) &gt; 0.3.

title: ADCP current measurements (38 kHz) during RV MARIA S. MERIAN cruise MSM107

description: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM107 were continuously collected by a vessel-mounted Teledyne RD Instruments 38 kHz Ocean Surveyor ADCP. The transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode with 32 m bins and a blanking distance of 16.0 m, while 50 bins were recorded using a pulse of 2.85 s. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). Heading, pitch and roll data from the ship's gyro platforms and the navigation data were used by the data acquisition software VmDas internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and the ship's heading data. Further errors stem from a misalignment of the transducer with the ship's centerline.Data post-processing included water track calibration of the misalignment angle (0.34° +/- 0.9292°) and scale factor (0.9996 +/- 0.0145) of the Ocean Surveyor signal. The average interval was set to 60 s. Velocity quality flagging is based on following threshold criteria: abs(UC) or abs(VC) &gt; 1.5 m/s, rms(UC_z) or rms(VC_z) &gt; 0.3.

title: Pedogenic carbonate nodule δ¹⁸O and δ¹³C record from the Pliocene-Pleistocene Villalba-Alta section, Teruel

description: Two sampling campaigns to the Teruel Basin, Spain were carried out in 2016 and in 2019. During the 2016 pilot expedition, 52 nodules (2-6 nodules per stratigraphic level) were collected and the section was measured as depth below the prominent cliff-forming conglomerate at the top of the section. During the 2019 expedition the section was measured as height above the lowest outcrop. 3-14 nodules were collected from each stratigraphic level at which nodules were observed resulting in 1,257 discrete soil carbonate nodules from 148 different heights. 312 nodules from 43 different heights were selected for stable isotope analyses. In the laboratory, nodules were split in half using a mallet and then the micrite was sampled with a Dremel drill avoiding spar. The resulting powders were then reacted with H₃PO₄ under 70°C to liberate CO₂ before being analyzed on a Thermo 253 isotope ratio mass spectrometer operating in continuous flow mode and interfaced with a Thermo Gasbench II at the University of Texas at Austin. Drift corrections were applied to the soil carbonate δ values using an internal Carrara marble (UTM) standard while laboratory standards NBS-18, NBS-19 were used to calibrate delta values to the PDB scale. The standards across all runs had an average reproducibility of 0.16‰. Additionally, spar and coexisting micrite from seven nodules were sampled separately, and analyzed using the same procedure to determine if they had δ¹⁸O values distinct from each other.

title: Seafloor bathymetric maps derived from side scan data collected along OFOBS profiles during POLARSTERN cruise PS124 to the southern Weddell Sea

description: The Ocean Floor Observation and Bathymetry System (OFOBS), used during Polarstern research cruise PS124 to the southern Weddell Sea , a towed underwater camera system equipped with both a high-resolution photo-camera (iSiTEC, CANON EOS 5D Mark III) and a high-definition video-camera (iSiTEC, Sony FCB-H11). The cameras were mounted on a steel frame (150L x 92W x 105H cm), together with two strobe lights (iSiTEC UW-Blitz 250, TTL driven), three parallel 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) to track the position of the OFOBS during deployments. Additionally mounted on the platform was an EdgeTech 2205 bathymetric side scan and BlueView M900-130 forward looking sonar systems, to become the Ocean Floor Observation and Bathymetry System (OFOBS). Auxiliary sensors include an iXBlue PHINS 6000, and an AML Micro-X 6000 SV-Xchange sound velocity probe. An iXBlue DVL system was installed to augment the output of the PHINS 6000.Within this data set, the bathymetric maps of the seafloor derived from the raw side scan data collected are provided at 10 and 20 cm resolutions.

An iXBlue DVL system was installed to augment the output of the PHINS 6000.The forward facing acoustic camera was particularly useful during the PS124 expedition as it revealed very clearly regions of the seafloor which had been used previously as nesting sites for ice fish. These abandoned nests were harder to distingusish from OFOBS camera images than from the acoustic forward facing camera data. Within this data set, all forward facing acoustic camera sonar data collected from the 20 deployments conducted during the cruise are presented.

title: Observational Notes on Anomaly Measures and Gravitational Amplification

description: Definitions

Let





μ_pk denote the baryonic surface density evaluated at the Einstein radius and normalized by a fixed critical surface density Σ_c.




Nlayer=ln⁡(Rout/RE)Nlayer=ln(Rout/RE) be the logarithmic boundary accumulation depth.




Ξ represent an effective gravitational amplification factor, such as a time-delay distance ratio or an effective convergence ratio relative to ΛCDM expectations.




A be an anomaly score obtained from an unsupervised morphological or variability-based detection method.





Prediction 1: Anomaly–amplification relation

For galaxy and lens samples drawn from wide-field optical surveys:

In subsamples restricted to μ_pk values close to 3, objects with larger anomaly scores A are expected to exhibit systematically larger values of Ξ.

When the same analysis is performed for subsamples with μ_pk well below or well above this range, no statistically significant dependence of Ξ on A is expected.



Prediction 2: μ-dependent scaling of boundary accumulation

For strong gravitational lens samples:

If lenses are grouped according to μ_pk, the dependence of Ξ on NlayerNlayer is expected to change qualitatively across μ_pk.

For μ_pk below the critical range, Ξ should show at most a weak (constant or approximately linear) dependence on NlayerNlayer.

In a narrow interval of μ_pk centered around μ_pk ≈ 3, Ξ is expected to increase approximately exponentially with NlayerNlayer.

For μ_pk significantly above this interval, the exponential trend is expected to weaken or saturate.



Falsifiability

The framework is disfavored if no systematic association between anomaly measures and gravitational amplification is found near μ_pk ≈ 3, or if an exponential dependence of Ξ on NlayerNlayer persists independently of μ_pk.



Note on timing

These statements were formulated prior to the availability of large-sample public data from next-generation wide-field surveys.

title: Paleo- and rock magentic data of core PS97/085-3

description: During Expedition PS97 of the Research Vessel POLARSTERN to the Drake Passage in 2016, three sediment cores, PS97/085-3, PS97/084-1, and PS97/079-2 were collected along the Shackleton Fracture Zone. The age model of core PS97/085-3 was constructed using a combination of radiocarbon dating and tie points from paleomagnetic and environmental tuning (refer to https://doi.org/10.1594/PANGAEA.923843). The age models of cores PS97/084-1and PS97/079-2 were determined by tuning their rock magnetic parameters to those of core PS97/085-3. Rock magnetic results indicate that the magnetic minerals in the three sediments cores are dominated by (titano-)magnetite and have well-preserved geomagnetic signals. This dataset includes rock magnetic results of bulk magnetic susceptibility, anhysteretic remanent magnetization (ARM), and saturated Isothermal remanent magnetization (SIRM), and paleomagnetic results of characteristic inclination and declination, natural remanent magnetization (NRM) after alternating field (AF) field of 30 mT (NRM30mT), and relative paleointensity (RPI). RPIs are determined by NRM30mT/SIRM for cores PS97/084-1, and PS97/079-2, and by ln(NRM30mT)/ARM for core PS97/085-3.

title: Last Interglacial annually to subdecadally resolved GDGT-based sea surface temperature record from sapropel S5 (Eastern Mediterranean)

description: We present annually to subdecadaly resolved GDGT-based (CCaT) sea surface temperature reconstruction from S5 sapropel layer recovered in the sediment core M51/3-SL104 (34.8247°N, 27.2925°E; water depth 2155 m) from the Pliny Trench region of the Eastern Mediterranean. We applied Mass Spectrometry Imaging (MSI) on finely laminated sapropel sediment in 200 µm resolution. We used CCaT ratio that was calibrated to SST. MSI was performed using a 7T solarix XR Fourier transform-ion cyclotron resonance-mass spectrometer (FT-ICR-MS) coupled to a matrix-assisted laser desorption/ionization (MALDI) source equipped with a Smartbeam II laser. The resulting time-series of alkenone-based sea surface temperature covers ~4.800 years in 1-4 year resolution. In the dataset are presented depth, age, CCaT values, calibrated SST time-series and associated uncertainty.
