title: Functional estimates from surface pollen samples in North America

description: Surface pollen samples were transformed from relative abundances to ecological function by linking plant functional traits to pollen datasets in North America to test the ability of the transformation to track ecological function at present. Trait measurements of all native plant species were log-transformed and scaled, and trait values were then assigned to each pollen taxon. Trait values are presented as the mean and standard deviations of all associated values. These values were then used to quantify the range of occupied trait space at each surface sample that were then averaged in 0.5º X 0.5º grid cells to reconstruct the latitudinal functional diversity gradient.

title: Seawater carbonate chemistry and live coral performance vs. framework dissolution and bioerosion

description: Physiological sensitivity of cold-water corals to ocean change is far less understood than of tropical corals and very little is known about the impacts of ocean acidification and warming on degradative processes of dead coral framework. In a 13-month laboratory experiment, we examined the interactive effects of gradually increasing temperature and pCO2 levels on survival, growth, and respiration of two prominent color morphotypes (colormorphs) of the framework-forming cold-water coral Lophelia pertusa, as well as bioerosion and dissolution of dead framework. Calcification rates tended to increase with warming, showing temperature optima at ~ 14°C (white colormorph) and 10–12°C (orange colormorph) and decreased with increasing pCO2. Net dissolution occurred at aragonite undersaturation (ΩAr &lt; 1) at ~ 1000 μatm pCO2. Under combined warming and acidification, the negative effects of acidification on growth were initially mitigated, but at ~ 1600 μatm dissolution prevailed. Respiration rates increased with warming, more strongly in orange corals, while acidification slightly suppressed respiration. Calcification and respiration rates as well as polyp mortality were consistently higher in orange corals. Mortality increased considerably at 14–15°C in both colormorphs. Bioerosion/dissolution of dead framework was not affected by warming alone but was significantly enhanced by acidification. While live corals may cope with intermediate levels of elevated pCO2 and temperature, long-term impacts beyond levels projected for the end of this century will likely lead to skeletal dissolution and increased mortality. Our findings further suggest that acidification causes accelerated degradation of dead framework even at aragonite saturated conditions, which will eventually compromise the structural integrity of cold-water coral reefs.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2021) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2022-12-21.

title: Physiological parameters from a long-term multiple stressor aquarium experiment with the cold-water coral Desmophyllum pertusum

description: We conducted a long-term (6 months) multiple driver aquarium experiment under future environmental conditions at St Abbs Marine Station (UK) with the cold-water coral Lophelia pertusa (syn. Desmophyllum pertusum) sampled from Tisler Reef (Skagerrak). The experiment with live corals consisted of four different treatments to investigate the combined effect of ocean acidification, warming, deoxygenation and food limitation on their physiology: 1) control (9 °C, pH 8.1, 100 % oxygen, 100 % food availability), 2) multiple stressor with high feeding (12 °C, pH 7.7, 90 % oxygen, 100 % food availability), 3) multiple stressor with low feeding (12 °C, pH 7.7, 90 % oxygen, 50 % food availability) and 4) reduced oxygen (9 °C, pH 8.1, 90 % oxygen, 100 % food availability). Every treatment consisted of three replicate tanks with four live corals (treatments 1-4). The physiological parameters were determined after 1.5, 3, 4.5 and 6 months of the experiment. Growth rates were measured using the buoyant weighing technique (Jokiel et al. 1978) and respiration rates were conducted using closed-cell incubations.
description: This dataset covers only the first 6 months of the experiment. Updated versions of the related datasets covering the entire 12-month experimental period are published (2025) and available for preferred reuse and are referenced here.

title: Accelerated discovery of topological metals for nanoscale interconnects

description: The sharp increase in resistivity of copper interconnects at ultra-scaled
 dimensions threatens the continued miniaturization of integrated circuits.
 Topological metals with gapless surface states (Fermi arcs) protected by
 bulk topological invariants offer robust, backscattering-immune
 conduction. We develop an efficient computational framework to quantify
 0~K surface-state transmission in TSM nanowires derived from Wannier
 tight-binding models that faithfully reproduce relativistic density
 functional theory results. Utilizing the non-equilibrium Green's
 function formalism, we systematically screen materials across chemical
 potentials and transport directions, producing a dataset of 3000 surface
 transmission values. This dataset supports machine learning models for
 rapid interconnect compound identification.

title: Age, annual coral growth rates and stable isotopes of coral sample Ningaloo

description: 116-year record of coral skeletal delta18O is presented from a colony of Porites lutea from Ningaloo Reef, western Australia. Interannual variability of sea-surface temperatures (SST) inferred from skeletal delta18O is dominated by a 9.5-year period, and may constitute a characteristic signal of the Leeuwin Current. On long-terms coral skeletal delta18O indicates a near-continuous increase of SST at Ningaloo Reef over one century. The skeletal delta18O time series was checked for the presence of seasonal cooling events resulting from major volcanic eruptions. An ~1 °C cooling is evident following the eruption of Pinatubo in 1991, which reproduces the results of previous investigations. However, only weak or no signals can be related to the eruptions of Krakatau (1883) and Agung (1963).

title: Sediment geochemical and stable isotope data of sediment core GPC04 at the Ninetyeast Ridge, Indian Ocean

description: We investigated benthic foraminifera in cores GPC03 and GPC04 in the northeast tropical Indian Ocean (TIO) over the past ~450 ka to evaluate the ballasting effect of particulate organic matter (POM) and the long-term zonal change during the mid-Brunhes dissolution interval (MBDI). Today, interannual climate and oceanographic variability in the TIO is governed by the Indian Ocean Dipole (IOD), which manifests as asymmetric zonal oceanographic change. Here we provide our sediment geochemical, stable oxygen and carbon isotope data and faunal data of benthic foraminifera in core GPC04.

title: Trophic levels and simple functional groups for taxa recorded in the Barents Sea between 2014-2016, based on literature

description: This dataset contains the Latin names and literature-based broad trophic and feeding occurrence (in terms of category of feeding depth zone) characteristics of 809 taxa recorded in the Barents Sea during scientific surveys by the Institute of Marine Research (IMR, Havforskningsinstituttet), Norway during the summers of 2014, 2015, and 2016. Trophic level (TL), functional group/guild (FG), broad group (e.g. mammal, fish, benthos), and depth group (DG, category of feeding occurrence to pelagic, benthopelagic, or benthic) were classified either directly from literature or based on e.g. congeners / similar organisms in similar areas with similar feeding habits. Each taxon is fully referenced, when relevant. These samples were taken during the annual IMR Ecosystem Surveys in the Barents Sea, and on surveys under the TIBIA (Trophic Interactions in the Barents Sea) and SI_ARCTIC projects. These surveys aim to monitor the organisms present, their geographic locations, abundance and biomass, and spatio-temporal changes to these in the Barents Sea ecosystem. Data were collected by pelagic and demersal trawls, and by plankton surveys.

title: Glycerol dialkyl glycerol tetraethers analysis of the last 15,000 years cal BP of the Canroute peatland sequence (Massif Central, France)

description: This dataset contains the relative abundance of isoprenoidal and branched glycerol dialkyl glycerol tetraethers (GDGT) components, in addition to various indexes used to reconstruct the mean annual air temperature and pH, of the Canroute peatland sequence (Massif Central, France) for the last 15,000 years cal BP. The analysis was performed by a double microwave extraction at 70°C with dichloromethane (DCM)-methanol (MeOH) mixture (3:1, v/v), filtered on a solid-phase extraction (SPE) cartridge and then separated into polar and apolar fractions on a silica column with a hexane-DCM (1:1, v/v) and DMC-MeOH (1:1, v/v) mixtures respectively. Samples were then analysed in hexane-propanol (98.2:0.2, v/v) by high-performance liquid chromatography with mass spectrometry (HPLC-MS). Ions in selected ion monitoring (SIM) are detected for mass-to-change ratios according to Hopmans et al. (2016, doi: 10.1016/j.orggeochem.2015.12.006). This data was used to better understand the biological origin of the components and reconstruct the environmental and paleoclimate of the Canroute peatland sequence.

title: Estimating epidemiological parameters of highly pathogenic avian influenza in common terns using exact Bayesian inference

description: Highly pathogenic avian influenza (HPAI) is a contagious viral disease
 that has led to the culling of huge amounts of poultry as well as the
 mortality of countless wild birds. The recent panzootic that began in 2021
 has been particularly notable for its devastating effect on seabird
 populations around the globe. Whilst transmission of HPAI within poultry
 has been relatively well studied, the recency of the current panzootic,
 combined with data collection challenges, means that much less is known
 about key epidemiological parameters, such as reproduction numbers, R0, of
 HPAI in wild populations. We develop methodology to carry out exact
 Bayesian parameter inference using reversible jump Markov chain Monte
 Carlo applied to mortality data in the form of daily carcass counts over
 the duration of subsequent outbreaks in a colony of common terns, Sterna
 hirundo, in 2022 and 2023. We estimate R0 to be 3.7 (95% CI 2.3; 7.2) in
 2022, and 3.2 (95% CI 1.7; 7.0) in 2023. The probability of mortality for
 an infected bird was estimated to drop from 0.26 (95% CI 0.24; 0.28) in
 2022 to 0.14 (95% CI 0.11; 0.20) in 2023. Our findings furthermore suggest
 direct bird-to-bird transmission to be the predominant driver of infection
 within the colony, with environmental transmission playing a negligible
 role.

title: Northern tropical Indian Ocean Mg/Ca derived SST for the last glacial termination, sediment core SSD004_GC03

description: Here, we reconstructed sea surface temperature (SST) and upwelling intensity record from the northern tropical Indian Ocean for the last glacial termination (8-24 kyr BP). The marine sedimentary archive was collected during forth voyage of ORV Sindhu Sadhana and SST record was reconstructed using Mg/Ca in G. ruber white (sensu stricto). The upwelling intensity was reconstructed using percentage abundance of G. bulloides. The record demonstrates that the northern tropical Ocean began warming well before the increase in the atmospheric carbo dioxide and has potential implications for the strengthening of the AMOC as well as the eventual glacial termination.

title: Nitrate raw measurements at lander 1 in the German Baltic Sea

description: Coastal ecosystems are heterogeneous environments with high turnover rates of carbon and nutrients that influence the distribution of greenhouse gases (GHG). They also represent challenging environments for scientific investigations, requiring new technologies that go beyond discrete sampling. Here we present temporal high-resolution measurements of several physicochemical variables, including the partial pressures of CO2 and CH4, made in shallow waters at around 6 m water depth of the Baltic Sea using two autonomous lander systems. The two landers were deployed at the sediment-water interface (bottom lander) and about 400 m offshore near the German city Rostock with support from the buoy tender “Rosenort” operated by the Wasserstraßen- und Schifffahrtsverwaltung des Bundes, Stralsund (WSA Stralsund). These landers were equipped with six commercially available state-of-the-art sensors. Field data resolution ranged from 10 seconds to 60 minutes and was obtained for partial pressure of CO2 (Contros HydroC-CO2) and CH4 (Contros HydroC-CH4), temperature, salinity, depth (hydrostatic pressure), O2 (CTD-O2 with SBE-37SMP-ODO), the concentrations of phosphate (SBE HydroCycle PO4), nitrate (SBE SUNA V2), chlorophyll a and the turbidity (both with SBE-FLNTUSB ECO) as stationary measurements at two different locations in close proximity. The CTD and oxygen measurements provide exact water depth data for the respective lander locations. In the other data sets (e.g., CO2 measurements) rounded data is inserted instead of the exact depth data, which is 6 m for lander_1 and 5 m for lander_2. The deployment and recovery of the landers and thus the measurements took place between 04 September 2019 and 04 October 2019 and the sensors were operated under battery power and a centralized timestamp. Three events common to coasts were observed during the deployment, allowing tracking of (1) an advection of saline waters with a mineralization signal, (2) a storm event of about 4 days, and (3) a stagnation event. Sensor data and processed data are available in separate files.
