title: Northern hemispheric land ice distribution outside of Greenland during the Quaternary

description: From the combination of orbital theory with benthic δ18O it has been suggested which obliquity cycles led to interglacials during the Quaternary. Here, we use a model-based deconvolution of this benthic δ18O record to calculate northern hemispheric land ice outside of Greenland, from which an alternative distribution of glacial and interglacial periods is defined.Model output is compared with independent reconstructions of δ18O_seawater, sea level and atmospheric CO2 concentrations.All data plotted in the figures of the article:Köhler, P. & van de Wal, R. S. W. Interglacials of the Quaternary defined by northern hemispheric land ice distribution outside of Greenland, Nature Communications, 2020, 11, 5124, doi:10.1038/s41467-020-18897-5.are compiled here.

title: Synthesised hyperspectral dataset for bio-optical algorithm development

description: A synthesised dataset comprising inherent optical properties (IOPs) and apparent optical properties (AOPs) is presented. The dataset has a hyperspectral resolution of 1 nm spanning 350 - 800 nm. The IOPs were first synthesised using bio-optical relationships. The IOPs were then input to Hydrolight-Ecolight 5.1 radiative transfer code to simulate apparent optical properties (AOPs).

title: Differential impacts of elevated CO2 and acidosis on the energy budget of gill and liver cells from Atlantic cod

description: Ocean acidification impacts fish and other marine species through increased seawater PCO2 levels (hypercapnia). Knowledge of the physiological mechanisms mediating effects in various tissues of fish is incomplete. Here we tested the effects of extracellular hypercapnia and acidosis on energy metabolism of gill and liver cells of Atlantic cod. Exposure media mimicked blood conditions in vivo, either during normo- or hypercapnia and at control or acidic extracellular pH (pHe). We determined metabolic rate and energy expenditure for protein biosynthesis, Na+/K+-ATPase and H+-ATPase and considered nutrition status by measurements of metabolic rate and protein biosynthesis in media with and without free amino acids (FAA). Addition of FAA stimulated hepatic but not branchial oxygen consumption. Normo- and hypercapnic acidosis as well as hypercapnia at control pHe depressed metabolic stimulation of hepatocytes. In gill cells, acidosis depressed respiration independent of PCO2 and FAA levels. For both cell types, depressed respiration was not correlated with the same reduction in energy allocated to protein biosynthesis or Na+/K+-ATPase. Hepatic energy expenditure for protein synthesis and Na+/K+- ATPase was even elevated at acidic compared to control pHe suggesting increased costs for ion regulation and cel- lular reorganization. Hypercapnia at control pHe strongly reduced oxygen demand of branchial Na+/K+-ATPase with a similar trend for H+-ATPase. We conclude that extracellular acidosis triggers metabolic depression in gill and metabolically stimulated liver cells. Additionally, hypercapnia itself seems to limit capacities for metabolic usage of amino acids in liver cells while it decreases the use and costs of ion regulatory ATPases in gill cells.

description: Herein, we publish the simulated global annual mean temperature (THO), salinity (SAO), ice compactness (SICOMO), Atlantic Meridional Overturning Circulation (AMOC), Global Meridional Overturning Circulation (GMOC), zonal velocity (UKO), meridional velocity (VKE), 10m u-velocity (u10), 10m v-velocity (v10), mixed layer depth (zmld), horizontal barotropic streamfunction (PSIUWE) and sealevel (ZO) over a time period of 100 years retrieved from equilibrium climate simulations for the Miocene (~23-15 Ma) and use different Greenland-Scotland Ridge (GSR) and Fram Strait (FS) sill depths as a representative for different tectonic settings that occur during the subsidence interval and utilized in the publication by Hossain et al. (2020). The climate data has been produced with COSMOS (ECHAM5/JSBACH/MPIOM/OASIS3), utilized at a resolution of T31 in the atmosphere (19 hybrid sigma-pressure levels) and a resolution of GR30 (bipolar orthogonal curvilinear grid, formal resolution of ~3.0°x1.8°) in the ocean (40 z-coordinate levels). The model setup refers to boundary conditions (incl. changes in orography, bathymetry, physical land surface characteristics, ice sheets, atmospheric CO2) representative for the Miocene. Details on setup and identifiers of Miocene model simulations can be found in Table 1 and Supplementary Table 1 of Hossain et al., 2020.

title: Datasets for the graphs of the paper (Fig. 2 to Fig. 7)

description: Investigating the relationship between factors (climate change, atmospheric CO2 concentrations enrichment, and vegetation structure) and hydrological processes is important for understanding and predicting the interaction between the hydrosphere and biosphere. The Integrated Biosphere Simulator (IBIS) was used to evaluate the effects of climate change, rising CO2, and vegetation structure on hydrological processes in China at the end of the 21st century. Seven simulations were implemented using the assemblage of the IPCC climate and CO2 concentration scenarios, SRES A2 and SRES B1. Analysis results suggest that (1) climate change will have increasing effects on runoff evapotranspiration (ET), transpiration (T), and transpiration ratio (transpiration/evapotranspiration, T/E) in most hydrological regions of China except in the southernmost regions; (2) elevated CO2 concentrations will have increasing effects on runoff at the national scale, but at the hydrological region scale, the physiology effects induced by elevated CO2 concentration will depend on the vegetation types, climate conditions, and geographical background information with noticeable decreasing effects shown in the arid Inland region of China; (3) leaf area index (LAI) compensation effect and stomatal closure effect are the dominant factors on runoff in the arid Inland region and southern moist hydrological regions, respectively; (4) the magnitudes of climate change (especially the changing precipitation pattern) effects on the water cycle are much larger than those of the elevated CO2 concentration effects; however, increasing CO2 concentration will be one of the most important modifiers to the water cycle; (5) the water resource condition will be improved in northern China but depressed in southernmost China under the IPCC climate change scenarios, SRES A2 and SRES B1.

title: Low-field magnetic susceptibility and magnetic parameters of the navigation channel dried grab samples

description: Low-field magnetic susceptibility of every sample was measured with an MFK1 susceptibilimeter (AGICO; K_LF ). The obtained value was normalized by the weight of the sample to determine the specific low-field magnetic susceptibility, X_LF . Determination of Anhysteretic Remanent Magnetization (ARM), Saturation Isothermal Remanent Magnetization (SIRM) and Isothermal Remanent Magnetization (IRM) was performed with a superconducting rock magnetometer SRM760R (2G enterprises). The ARM is an artificial magnetization gained in an alternating magnetic field of 100 mT superimposed on a steady field of 50 µT, which is comparable to the strength of the geomagnetic field. The ARM is afterward subject to demagnetization at 30 mT (ARM_30 ). The SIRM was acquired at 3 T and the IRM at 0.3 T in the opposite direction using a pulse magnetizer MMPM9 (Magnetic Measurements ltd). The S-ratio was calculated after the formula 0.5(1-IRM/SIRM) and allows for an estimation of the relative abundance of high coercivity minerals. TheS-ratio comesclose to 1when low-coercive mineralssuch a as magnetite dominate the signal, and decreaseswith increasing amount of high-coercive mineralssuch as hematite (Bloemendal et al., 1992).The Hard Isothermal Remanent Magnetization (HIRM) was calculated after the formula (SIRM-IRM)/2 and allows for an estimation of the absolute concentration of high coercivity minerals (e.g. hematite).ARM/SIRM is used as an estimator of the relative magnetic grain size. ARM_30 /ARM is also used as a magnetic grain-size estimator since samples display a constant mineralogy.

title: High-resolution black carbon data of firn core OH-12 from Plateau Laclavere, northern Antarctic Peninsula

description: The firn core OH-12 was retrieved from Plateau Laclavere, a small ice cap on the northernmost end of the Antarctic Peninsula at about 1090 m above sea level in January 2016. The core was drilled down to 19.93 m depth. Glacio-chemical parameters (hydrogen peroxide, sulphur, sodium, black carbon) were determined in summer 2017 using a Continuous Flow Analysis (CFA) system as described by Röthlisberger et al. (2000) and McConnell et al. (2002, 2007). Black carbon (BC) was analyzed with a Single Particle Soot Photometer inter-cavity laser system (SP2, Droplet Measurement Technologies). The core was dated using annual layer counting of hydrogen peroxide measurements. We additionally accounted for precipitation intermittency at the drill site by using precipitation data from the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 Reanalysis extracted from the grid point closest to the firn-core drill site. The core covers the period from July 2011 to January 2016. The data has been used for investigating recent climate and environmental changes in the northern Antarctic Peninsula region providing the basis for the retrieval and analysis of a deeper ice core from the same site.
