description: Testing eggs with uncertain data integrity:
The aim of this study is to validate or refute the authenticity of rare or unusual species records that have eggshells as the basis of the record. To achieve this goal, we also generated the high-quality mitochondrial reference genomes for avian species that did not already have a representative in NCBI. A total of 5 egg clutches were tested and a total of 20 high quality mitochondrial reference genomes were generated. This was a pilot study to evaluate the feasibility of conducting future externally funded eggshell genomics projects.

title: From boom to bust: real commodity prices from 1850

description: This is the annual update of Jacks, D.S. (2019), “From Boom to Bust: A Typology of Real Commodity Prices in the Long Run.” Cliometrica 13(2), 201-220. It analyses an accompanying dataset on 42 commodities, comprising 7.43 trillion USD worth of production in 2019 and spanning the years from 1850 to 2023. It also presents evidence on three commodity price indices using various weighting schemes for the period from 1900 to 2023. Applying weights drawn from the value of production in 1975, real commodity prices are estimated to have increased by 41.13% (or 0.28% per annum) from 1900, 47.42% (or 0.53% per annum) from 1950, and 16.01% (or 0.31% per annum) from 1975. The data also indicates the presence of three complete commodity price cycles, entailing multi-year positive deviations from the long-run trend. The most recently completed cycle began in 1996, reached its peak in 2010, and is now near its trough.

title: TEAMER: Electrically Engaged Undulation System for Unmanned Underwater Vehicles

description: This TEAMER RFTS 1 (Request for Technical Support) project supported the flume tank testing of a long range, high endurance unmanned underwater vehicle (UUV) to monitor maritime space. Today, battery-powered remotely operated vehicles (ROVs) lack the duration to make persistent, wide-area data collection possible.The proposed solution, an Electrically Engaged UnduLation (EEL) drone, can sustain missions for longer duration through hydrodynamic energy harvesting. Power is provisioned via the piezoelectric effect, a material-led phenomenon that converts applied stress into electricity. The EEL subsystems include power, propulsion, navigation, ballast, telemetry, and instrumentation. By mimicking the gait of aquatic eels, EEL can counter currents during maneuvering and level-flight. The identified opportunity is in the future capability of extreme endurance UUVs in swarms. The specific goal for the EEL development is to expand the spatio-temporal coverage of the existing ocean observation mission by overcoming significant challenges of autonomous robotics. Some of the challenges presented include novel compliant mechanism for robust actuation, bio-inspired design to emulate efficient locomotion, smart material-based energy harvesting for sustained power, and swarming architecture through enabled autonomy.

title: Morphometric data of Aegocrioceras spp. from the clay pit Resse (Bed 82), NW Germany

description: Despite the fact that heteromorph ammonites often show a large range of intraspecific variation, that variation has rarely been quantified. Here, we quantify the intraspecific variation and ontogeny of 85 newly collected specimens of the Hauterivian endemic ammonite genus Aegocrioceras. All specimens have been collected from concretions in the newly exposed bed 82 in the clay pit Resse in NW Germany (Lower Saxony Basin). Data for the conch morphology (diameter, whorl height, whorl interspace, rib spacing) have been collected in 45° steps using the new software CONCH. The CONCH software will be made officially available with this publication. All ammonites have been a priori identified as A. bicarinatum or A. semicinctum. An assessment of the intraspecific variation of this population demonstrates the presence of just one species, i.e., A. bicarinatum. Comparison with the type material of A. bicarinatum and A. semicinctum reveals large morphological overlap of different shell parameters and does not support a separation of both forms as independent species. The analyzed population of A. bicarinatum has a high variation in shell morphology including whorl interspace, umbilical width, and whorl expansion. Further, the changes in intraspecific variation through ontogeny have been quantified and the presence or absence of sexual dimorphism within the population is discussed.

title: Chlorophyll pigments from the Laptev Sea (Arctic Ocean) during POLARSTERN cruise ARK-XXVII/3 from August-September 2012

description: Sampling was conducted with a TV-guided multiple corer (MUC), in order to retrieve undisturbed sediment cores. Upon retrieval of the MUC, the overlying water was carefully removed from each core and the core was cut into the following sediment horizons using a steel plate and a custom-made plastic ring: 0-1 cm, 1-5 cm, 5-10 cm. At each station, sediment samples from three replicate cores were pooled and transferred to a cooling container (0°C), where subsamples for chloroplastic pigment analyses were taken and processed directly on board.Chloroplastic pigments were extracted from 1 ml sediment with 3 x 8 ml acetone (90%), including the addition of glass beads and grinding of the samples in a cell mill according to Boetius & Damm 1998 (doi:10.1016/S0967-0637(97)00052-6). Samples were centrifuged and chlorophyll a and phaeopigment (after addition of 250 µl 25% HCl) concentrations were determined in the superanatant by fluorometric measurement with a Turner Trilogy fluorometer. Measurements were performed in triplicate for each sample.

title: Shell size and weight data of Trilobatus sacculifer shells off Puerto Rico (Caribbean Sea)

description: The state of a population of planktic foraminifers at a certain time reflects multiple processes in the upper ocean, including environmental conditions to which the population was exposed during its growth, the age of the cohorts, and spatiotemporal patchiness. We carried out depth-stratified (0-60, 60-100 m) replicated sampling off Puerto Rico in autumn 2012, revisiting three stations previously sampled in autumn 1994 and spring 1995, in order to analyze seasonal and interannual variability of planktic foraminifers and the stable isotopic composition of their tests. The merged dataset from all three sampling campaigns allows us to assess short- and long-term changes in foraminiferal population dynamics and the spatial assemblage coherency along the shelf edge. All three sample series cover more than 2 weeks during either spring (1995) or autumn (1994, 2012) and include the time of the full moon when reproduction of some surface-dwelling planktic foraminifers has been postulated to take place. Our analyses indicate that interannual variability affected the faunal composition, and both autumn assemblages were characterized by oligotrophic tropical species, dominated by Trilobatus sacculifer and Globigerinoides ruber (white and pink variety). However, G. ruber (white) had a higher abundance in 1994 (37 %) than in 2012 (3.5 %), which may be partially due to increasing sea surface temperatures since the 1990s. Between 60 and 100 m water depth, a different faunal composition with a specific stable oxygen isotope signature provides evidence for the presence of the Subtropical Underwater at the sampling site. Measurements on T. sacculifer sampled in autumn 2012 revealed that test size, calcification and incidence of sac-like chambers continued to increase after full moon, and thus no relation to the synodic lunar reproduction cycle was recognized. During autumn 2012, outer bands of hurricane Sandy passed the Greater Antilles and likely affected the foraminifers. Lower standing stocks of living planktic foraminifers and lower stable carbon isotope values from individuals collected in the mixed layer likely indicate the response to increased rainfall and turbidity in the wake of the hurricane.

title: Organic and inorganic data of ODP Hole 177-1088B

description: Oxygen and carbon isotopes were measured for several planktonic foraminifera species (Globigerina bulloides, Neogloboquadrina pachyderma sinistral (sin.), Globoconella spp.) and the benthic foraminifera genus Cibicidoides spp. in samples from Ocean Drilling Program (ODP) Site 1088B. Typically, 10-15 planktonic specimen and five benthic specimen larger than 150μm were picked per sample. Foraminifera were crushed, rinsed twice with deionized water and once with MeOH and dried overnight at 50°C. Samples were analyzed at ETH Zurich on a GAS BENCH II system coupled to a Delta V Plus irMS (Thermo Scientific) following procedures described by Breitenbach and Bernasconi (2011). Analytical precision after system calibration by two in-house standards and international standards NBS-19 and NBS-18 was 0.07‰ for both stable isotopes. Values are reported relative to the VPDB standard.Different alkenone ratios (U_37^k' and C37.2/C38.2) were directly estimated with a Thermo Scientific Trace 1310 Gas Chromatograph (GC) equipped with a flame ionization detector (FID). Lab-sample replicates and in-house alkenone standard were injected every sequence to determine instrument drift and to guarantee long-term validation giving a precision of 0.025 U_37^k' units. Alkenone-derived SST was calculated from U_37^k' using the global calibration from Müller et al. (1998).Carbon isotopic compositions of C37.2 alkenones were measured on a Thermo Scientific Delta V mass spectrometer interfaced with a Thermo Scientific Trace 1310 Gas Chromatograph (GC-irMS) at ETH Zurich. Replicates, in-house alkenone standard, and known isotopic mixtures A5 and B4 (supplied by Arndt Schimmelmann, Univ. of Indiana) were injected at every sequence to determine the analytical accuracy of the measurement and an uncertainty of 0.4‰ is reported. Carbon isotopes are reported relative to the Vienna PeeDee Belemnite (VPDB) standard.The isotopic fractionation (εp) during photosynthetic fixation of carbon between [CO2]aq and algal biomass is calculated using the equation originally described by Freeman and Hayes (1992). The carbon isotopic composition of C37.2 alkenones represents the organic part whereas carbon isotopes from the planktonic formaninifera species N. pachyderma sin. are used as an assumption of dissolved inorganic carbon. To carefully include and propagate the uncertainties of each parameter introduced, a full Monte Carlo simulation (n = 10'000) was conducted and the respective 1 sigma confidence intervals are reported in this table.A quantitative estimation of the mean size of the alkenone producing coccolithophorid Reticulofenestra pseudoumbilicus was carried out using polarized light microscopy and the C-Calcita software (Fuertes et al., 2014).

title: Modelled gamete fusion numbers in planktonic foraminifera

description: Reproductive biology is integral to evolutionary processes in organisms, yet gaining detailed insights poses major challenges. Planktonic Foraminifera are globally distributed marine protists and important contributors to the global carbon cycle with distinct biodiversity patterns. Knowledge on their life cycle remains incomplete, yet the production of flagellated gametes implies a sexual mode of reproduction. In the open ocean, this would rely on sufficient gamete encounters to maintain viable populations, which is problematic for protist plankton with low population densities. We applied dynamic modelling with parameters based on prior observations to verify if random gamete encounters are sufficient for maintaining viable populations. Temporal and spatial synchronization of gamete release seems inevitable to that end, and planktonic Foraminifera seemingly optimized their individual reproductive success at the expense of gene flow. This may explain their high degree of diversity and contributes to our understanding of plankton ecology and evolution.

title: Chlorophyll a-content of all (total), the small (0.2-2 μm) and the large (&gt; 2 μm) cells determined from the community sampled at station West and East (PS97) before and after exposure to different Fe and Mn availabilities

description: Two Fe-Mn bottle amendment experiments with two natural phytoplankton communities were performed during Polarstern expedition PS97 in 2016 in the Drake Passage. At two locations, sea water was pumped (using trace metals clean techniques) from 25m depth and used to fill polycarbonate bottles after having passed through a cleaned 200 μm mesh (removing large grazers). The Control treatment was the sampled seawater without any trace metals addition while the other three treatments were enriched with either FeCl3 alone (0.5 nM; +Fe treatment) or MnCl2 alone (1 nM; +Mn treatment) or both trace metals together (+FeMn treatment). All treatments were done in triplicate 2,5L PC bottles. All incubation bottles were maintained at 30 μmol photons m-2 s-1 under a 16:8 (light:dark) hour cycle at 1 ̊C.Chlorophyll a samples were taken at the beginning and the end of both experiments. In order to compare the contribution of large (&gt;2 μm) relative to small cells (0.2-2 μm), 250 mL (on average) of samples were filtered onto 0.2 μm (for the total fraction) and 2 µm (for the large fraction) polycarbonate filters, hence the small fraction was calculated as the difference of the total and the large fraction. All samples were directly flash frozen into liquid nitrogen (N~2~) and then stored at −80 ̊C in the dark until further analysis. After being homogenized, samples were extracted in 90% acetone for 24h at 4 ̊C in the dark and analyzed fluorometrically on a Trilogy Fluorometer.
