    Description: Here, we present a global compilation of previously reported sightings of the rare planktic foraminifer Globorotalia cavernula Bé, 1967 as well as new observations of live-collected specimens from the Southern Ocean (Subantarctic south of Africa). The goal of this synthesis is to provide the geographic and stratigraphic context needed to investigate the past and present-day distributions of this rare but possibly under-recognized species. The previous records include modern occurrences in the water column (collected by plankton net tows and a single sediment trap) and seafloor sediments ranging in age from recent to Eocene. Seafloor sediment samples were collected by dredge, sediment grabs and core-tops. Deeper sediments came from drilling cores. Existing databases provided a foundation for this compilation, particularly ForCenS for surface sediments (Siccha & Kucera, 2017) and FORCIS for water-column collections (de Garidel-Thoron et al., 2022; Chaabane et al., 2022, 2023). These records were supplemented with occurrences from the literature, PANGEA, and cruise reports of the Deep Sea Drilling Project (DSDP) / Ocean Drilling Program (ODP). Searches were conducted in October 2022 using Google Scholar, GBIF, EOL (Encyclopedia of Life, "http://eol.org", which includes records from the Smithsonian NMNH). Where available, we include information on the abundance of G. cavernula in each collection, and indicate whether photographic evidence (or drawings) could be found to support the identification. Globorotalia crozetensis Thompson, 1973 (reclassified as G. cavernula by Brummer & Kučera, 2022) and closely related Globorotalia petaliformis Boltovskoy, 1974 were also included in compilation.

Spring data span 2017, 2018, 2020 and 2021 whereas autumn data span 2018-2021. The reason data for spring 2019 are omitted is due to observer error which resulted in a number of inconsistencies so the entire season has been omitted.

    Description: Gypsum samples collected in two outcrops located in the Polemi basin, Cyprus, have been analyzed for their triple oxygen and hydrogen isotopic composition. Respective methods are described in the original publication. The oxygen and hydrogen data provided here is derived from the crystal bound H2O within the Gypsum (CaSO4*2H2O), which allows calculating paleo-water isotopic compositions of the mother brine from which this gypsum precipitated during the Messinian Salinity Crisis. Because the isotopic composition of the mother brine is affected by the local hydroclimate at that time, such analyses allow reconstructing paleo-hydroclimate. One aim of the study was to reconstruct paleo-relative humidity of the Messinian Salinity Crisis. For this purpose, the triple oxygen and hydrogen isotope data was fitted to an appropriate isotope model that is based on the Craig and Gordon formula, which provides absolute paleo-relative humidity estimates. Model input and output data are summarized in Table S2.

    Description: This dataset contains planktic foraminifera Trilobatus sacculifer and Dentoglobigerina venezuelana stable oxygen isotopes, Mg/Ca, local seawater δ18O and ΔT estimates from Site NGHP-01-01A, which was recovered by the drill ship JOIDES Resolution (JR) in the Kerala-Konkan Basin in the Eastern Arabian Sea (EAS; 15º18.366' N, 70º54.192' E; 2663 m water depth) during the Indian National Gas Hydrate Program (NGHP) Expedition 01 in 2006 (28.04.-19.08.2006). The data archived here was generated to reconstruct changes of the upper water column structure, i.e., depth of the mixed later and thermocline at Site NGHP-01-01A in the EAS during the middle Miocene in order to study changes in the summer South Asian Monsoon (SAM). The isotopic composition of the planktic foraminifera samples was analysed at the MARUM, University of Bremen, Germany, using a Finnigan MAT 251 mass spectrometer equipped with an automatic line for carbonate preparation (type "Kiel III"). Planktic foraminiferal trace element concentrations were measured using an Inductively Coupled Plasma Optical Emission Spectrophotometer (ICP-OES; Agilent 5110 VDV) at the Center of Major Equipment and Technology (COMET) of the State Key Laboratory of Marine Environmental Science (MEL), Xiamen University. Planktic foraminiferal Mg/Ca ratios were converted to temperature using the the multiple species planktic foraminifera calibration of Anand et al. (2003; doi:10.1029/2002PA000846). To account for past seawater Mg/Ca changes, the D. venezuelana and T. sacculifer Mg/Ca estimates were adjusted for changes in seawater Mg/Ca by modifying the Mg/Ca-temperature calibrations of Anand et al. (2003; doi:10.1029/2002PA000846), following Lear et al. (2015; https://doi.org/10.1002/2015PA002833. Seawater δ18O (δ18Osw) was calculated using the unadjusted and adjusted temperature Mg/Ca-temperature estimates in order to account for past seawater Mg/Ca changes by removing the temperature-driven component of the planktic foraminifera δ18O record. The δ18O-temperature relationship of (Bemis et al., 1998; https://doi.org/10.1029/98PA00070) was used to calculate the δ18Osw estimates. A local record of changes in δ18Osw was derived by subtracting an estimate of middle Miocene ice-volume changes from the δ18Osw record. In order to reconstruct the upper surface water column structure in the EAS, the difference in Mg/Ca-based temperatures (ΔT˚C) of surface-dwelling (Trilobatus sacculifer) and sub-thermocline-dwelling (Dentoglobigerina venezuelana) planktic foraminifera was calculated to estimate the upper ocean thermal gradient. The age model of all provided datasets is based on Yang et al. (2020; doi:10.1029/2020PA003853).

    Description: Carbon cycle models used to interpret the IntCal20 compilation of atmospheric ∆14C have so far neglected a key aspect of the millennial-scale variability connected with the thermal bipolar seesaw: changes in the strength of the Atlantic meridional overturning circulation (AMOC) related to Dansgaard/Oeschger and Heinrich events. Here we implement such AMOC changes in the carbon cycle box model BICYCLE-SE to investigate how model performance over the last 55,000 years is affected, in particular with respect to available 14C and CO2 data. Thus, this data set contains: (a) Carbon cycle simulation output of the BICYCLE-SE model covering the last 55,000 years consisting of changes in marine reservoir age (MRA) of the whole ocean, or of the deep ocean in different basins (Atlantic, Southern Ocean, Indo-Pacific), non-polar surface ocean MRA, atmospheric CO2, atmospheric D14C, 14C production rates in 18 scenarios, which differ in boundary conditions (prescription of atmospheric carbon inventories) and changes in the strength of the AMOC in order to meet changes in marine 14C age as provided by data. (b) Six splines of intermediate (0.2-2.0 km) and deep (〉2km) ocean marine reservoir age in Atlantic, Southern Ocean, Indo-Pacificof the past 25,000 years based on benthic 14C data as compiled in Skinner et al., 2023 (doi: 10.5194/cp-19-2177-2023), related to data set doi:10.1594/PANGAEA.960693.

Spring data span 2017, 2018, 2020 and 2021 whereas autumn data span 2018-2021. The reason data for spring 2019 are omitted is due to observer error which resulted in a number of inconsistencies so the entire season has been omitted.
