title: Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy ZS2014: 120 s after the heating cycle

description: Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA ZS2014 is an autonomous instrument that was installed on landfast ice in Prydz Bay, East Antarctica, in May 2014. The buoy was deployed at 69.37°S; 76.36°E, ~100 m from the coast of Station Zhongshan with initial thicknesses of snow and ice of 0.02 and 0.57 m, respectively, on 13 May 2014. The thermistor chain was 5 m long and included 240 sensors with a regular spacing of 2cm. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of depth and time between 13 May and 23 November 2014 in sample intervals of 6 hours for temperature and 24 hours for temperature differences.

title: Dissolved inorganic carbon and total alkalinity of seawater samples from a Weddell Sea coastal polynya during two tidal observation case studies for RV POLARSTERN expeditions PS89 and PS117

description: Discrete seawater samples in a Weddell Sea coastal polynya along the Ekström Ice Shelf were collected from two sets of repeat CTD casts, capturing tidal variability in the water column. One set was collected during RV POLARSTERN expedition PS89, between 8 and 11 January 2015. The second set was collected during RV POLARSTERN expedition PS117, between 11 and 12 January 2019. Dissolved inorganic carbon (DIC) and total alkalinity (TA) were measured using coulometric titration and potentiometric titration, respectively, on a VINDTA 3C system. DIC and TA have been normalised to salinity: nDIC and nTA. Nutrients were measured with UV-Vis spectrophotometry and a continuous gas-segmented flow auto-analyser.
description: A fraction of oceanographic profiles (from CTD casts), the temperature, salinity, oxygen, and nutrient data have already previously been published (https://doi.org/10.1594/PANGAEA.910673). We have included these to maintain consistency with the rest of the profiles in the dataset (for which these variables have not been published yet). In addition to the fact that exactly these data were used in the calculations for the marine carbonate system in Droste et al. (2022), it is also easier for users to work with this dataset in the future. The DOI of the already published data is included in the comment column of the dataset itself. Details on sample collection, analysis methods, and salinity-normalisation of DIC and TA can be found in Droste et al. (2022).

title: Urban canopy parameterization data for urban climate simulation using CCLM/DCEP and hourly 2m temperature output

description: This dataset includes artificial/scenario Urban Canopy Parameterization (UCP) data for urban climate modelling with COSMO-CLM/DCEP and the hourly 2-meter temperature output of the corresponding simulations. Each simulation has a resolution of 0.009 degree (~1km) and covers a domain of around 300x300km centred at Berlin area. The temperature output covers a 1-week heatwave event which lasted from 1st to 7th of August 2003. All the simulations are driven by the same lateral boundary climate data down-scaled from ERA-Interim data, and the purpose of the work is to study the influence of urban morphology on urban heat island effect. UCP files are created using R package (https://github.com/sebschub/dcepucp) by incorporating designed scenarios (varying urban forms) of detailed urban street canyon structures which include urban fraction, street canyon orientation, building width, street canyon width and building height distribution. The details about the generation of the UCP dataset and conducted simulations can be found in Li Y, Schubert S, Rybski D, Kropp JP (2020): Urban Form and Heat. Nature Communications.

title: Grain size section mean data between 1340-2121 m of the EGRIP ice core derived with the Fabric Analyzer G50

description: Mean ice grain size and crystal-preferred orientation data was obtained from vertical thin sections (ca. 6.7 x 9 cm²) of the East Greenland Ice Core Project (EGRIP) ice core to analyze the microstructural evolution and internal deformation with depth. Vertical ice thin sections were prepared and measured with the Fabric Analyzer G50 (resolution: 20 μm/pixel) in the field at the EGRIP site in the summer seasons between 2018 and 2019, and at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research. 55 cm long sample were cut into six thin sections and used to calculate mean grain size values for these 9 cm long sections with the program cAxes between 1340 and 2121 m of depth. The stated depths of the section represent the top, center, and bottom of the section.

title: Seawater carbonate chemistry and calcification rates of tropical zooxanthellate corals (Stylophora pistillata, Pocillopora damicornis, and Seriatopora hystrix) and cold-water coral (Lophelia pertusa)

description: Corals are globally important calcifiers that exhibit complex responses to anthropogenic warming and acidification. Although coral calcification is supported by high seawater pH, photosynthesis by the algal symbionts of zooxanthellate corals can be promoted by elevated pCO2. To investigate the mechanisms underlying corals' complex responses to global change, three species of tropical zooxanthellate corals (Stylophora pistillata, Pocillopora damicornis, and Seriatopora hystrix) and one species of asymbiotic cold-water coral (Desmophyllum pertusum, syn. Lophelia pertusa) were cultured under a range of ocean acidification and warming scenarios. Under control temperatures, all tropical species exhibited increased calcification rates in response to increasing pCO2. However, the tropical species' response to increasing pCO2 flattened when they lost symbionts (i.e., bleached) under the high-temperature treatments—suggesting that the loss of symbionts neutralized the benefit of increased pCO2 on calcification rate. Notably, the cold-water species that lacks symbionts exhibited a negative calcification response to increasing pCO2, although this negative response was partially ameliorated under elevated temperature. All four species elevated their calcifying fluid pH relative to seawater pH under all pCO2 treatments, and the magnitude of this offset (Δ[H+]) increased with increasing pCO2. Furthermore, calcifying fluid pH decreased along with symbiont abundance under thermal stress for the one species in which calcifying fluid pH was measured under both temperature treatments. This observation suggests a mechanistic link between photosymbiont loss ('bleaching') and impairment of zooxanthellate corals' ability to elevate calcifying fluid pH in support of calcification under heat stress. This study supports the assertion that thermally induced loss of photosymbionts impairs tropical zooxanthellate corals' ability to cope with CO2-induced ocean acidification.
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 2022-12-19.

title: Posterior Amazon monthly mean surface carbon flux between 2010 and 2018 estimated using the INVICAT 4D-Var inverse model

description: This data set consist of a single netcdf file with a set of optimised global surface carbon fluxes (CO2), estimated by variational inverse methods using the TOMCAT chemical transport model, and the INVICAT inverse transport model. We assimilate in-situ surface flask observations from global surface observation sites and Amazonian lower-troposphere vertical profiles of CO2. The vertical profile data used here are available at PANGAEA Data Archiving, at https://doi.org/10.1594/PANGAEA.926834 and more details could be found at Gatti et al. (2021). These surface fluxes are monthly mean values for total emissions (labelled TOTAL_FLUX) on the (approximately) 5.6-degree horizontal model grid. The associated uncertainty for the flux from each grid cell is also included (labelled TOTAL_FLUX_ERROR). The fluxes and uncertainties cover the period of January 2010 to December 2018 and units are gC/m2/day, and time units are days since January 1st 2010. Further details about the data can be found in Basso et al. (2023) in the documentation section.

title: Oxygenated bottom water conditions on Broken Ridge (central Indian Ocean) in the last 9 million years

description: The late Miocene and early Pliocene were marked by widespread oxygen depletion in the Pacific and Indian Oceans in conjunction with the so-called "Late Miocene Biogenic Bloom" (LMBB). As the oxygen depletion progressed, it was accompanied by an oxygen minimum zone (OMZ) expansion, hypothesized to extend as far south as Broken Ridge (31°S), Indian Ocean. Here, we used benthic foraminiferal (BF) assemblage from Ocean Drilling Program (ODP) Site 752 (ODP Expedition 121) to reconstruct the bottom water dissolved oxygen concentration on Broken Ridge during the last 9 million years. Taxonomic analyses on the &gt;63μm fraction allowed the identification of 93 BF species and reported as benthic foraminifera row counts. The relative frequencies derived from BF row counts were used to determine diversity using the Fisher Alpha index and dissolved oxygen concentration was reconstructed using the Enhanced Benthic Foraminifera Oxygen Index. Benthic foraminifera with abundances below 5% across all samples were removed before statistical analysis to retain a robust signal of BF distribution without single and scattered occurrences. High abundance BF was reported in the grouped benthic foraminifera counts. Our results indicate well-oxygenated (dissolved oxygen concentration &gt;3ml/L) bottom water conditions in the last 9 million years.
