title: Ocean and climate response to North Atlantic seaway changes at the onset of long-term Eocene cooling

description: Here we publish simulated early-middle Eocene annual mean ocean temperature, salinity, density, mixed layer depth and current velocities (at the depth of ~1500 m) with different gateways configurations in the North Atlantic region. The details of original paleogeography, compiled by GETECH, are provided in Vahlenkamp et al. [2018, doi:10.1016/j.epsl.2017.12.016]. The CO2 level is set to 840 ppm, while the obliquity to a minimum value. All data are averaged over the period of 100 years. All simulations were run with COSMOS (ECHAM5/MPIOM/OASIS3). The atmosphere component ECHAM5 was run in the resolution of T31/L19, while the ocean model MPIOM has a formal resolution of ~3.0°x1.8°. OASIS3 is a coupler between the atmosphere and ocean components.The gateway alterations with respect to original paleogeography include an opening of the Arctic and Tethyan Seaways, as well as changing the depth of the Greenland-Scotland Ridge to 50 m and 200 m [Vahlenkamp et al., 2018, doi:10.1016/j.epsl.2018.06.031]. We publish also one experiment with higher, 1000 ppm CO2 level. In order to compare our simulated temperatures with the data, we have collected 30 Eocene temperature reconstructions from literature. We compared these reconstructions with the zonal surface air temperatures as well as zonal surface ocean temperatures (annual, boreal winter and summer) from our base simulation. All data used are provided in this dataset.
description: In each NetCDF file there are variables:THO - ocean temperature,SAO - ocean salinity,UKO - zonal ocean currents (shown only at the depth of 1.5 km),VKE - meridional ocean currents (shown only at the depth of 1.5 km),rhopoto - ocean density.In the file cntrl840 there are also variables:THO_DJF and THO_JJA: boreal ocean winter and summer temperatures,tsurf, tsurf_DJF and tsurf_JJA: surface air temperature (annual, boreal winter and summer).All details are explained in the manuscript.

title: The effect of stress on limestone permeability and effective stress behavior of damaged samples - original data used for figures

description: The evolution of permeability and its effective stress behavior is related to inelastic deformation and failure mode. This was systematically investigated in Indiana and Purbeck limestones with porosities of 16% and 14%, respectively. High‐pressure compression tests were conducted at room temperature on water‐saturated samples. At relatively high confinement shear‐enhanced compaction was observed to initiate at a critical stress, accompanied by significant permeability reduction of up to a factor of ~3. Overall, the permeability reduction due to inelastic compaction in our limestones is smaller than that observed in sandstones. At relatively low confinement, dilatant failure was observed, which was accompanied by a decrease and increase of permeability in Indiana and Purbeck limestones, respectively. There seems to be a trend for the correlation between porosity and permeability changes to switch from positive to negative with increasing porosity. The void space of both limestones has significant proportions of macropores and micropores. The effective stress behavior of such a limestone with dual porosity has been documented to be different from the prediction for a microscopically homogeneous assemblage, in that its effective stress coefficients for permeability and pore volume change may attain values significantly &gt;1. In contrast, our investigation of damaged samples consistently showed effective stress coefficients for both permeability and pore volume change with values &lt;1. This suggests that the behavior in the damaged samples is akin to that of a microscopically homogeneous assemblage, possibly due to pervasive collapse of macropores that would effectively homogenize the initially bimodal pore size distribution.
description: The samples include the Indiana limestone and Purbeck limestone.Indiana limestone is from USA with a porosity of 16%.Purbeck limestone is from UK with a porosity of 14%.Pc represents confining pressure.Pp represents pore pressure.

title: Mesozooplankton adundance during Mikhail Lomonosov cruise ML27, Part IV

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 125 µm. Additionally, the JUDAY oceanic model JOM with 300 µm mesh size and 80 cm ring diameter was used. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-300, 300-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

title: List of grains and results of the Scanning SQUID Magnetometer (SSM) scan

description: Obtaining reliable information from even the most challenging paleomagnetic recorders, such as the oldest igneous rocks and meteorites, is paramount to open new windows into Earth's history. Currently, such information is acquired by simultaneously sensing millions of particles in small samples or single crystals using SQUID magnetometers. The obtained rock-magnetic signal is a statistical ensemble of grains potentially differing in reliability as paleomagnetic recorder due to variations in physical dimensions, chemistry and magnetic behavior. Here we go beyond bulk magnetic measurements and combine computed tomography and scanning magnetometry to uniquely invert for the magnetic moments of individual grains. This enables us to select and consider contributions of subsets of grains as a function of particle-specific selection criteria and avoid contributions that arise from particles that are altered, or contain unreliable magnetic carriers. This new, non-destructive, method unlocks information from complex paleomagnetic recorders that until now goes obscured.

title: Experiment I: Effect of temperature and salinity on metamorphosis to cyprids (Fig. 1c)

description: Experiment I - nauplius to cypris developmentTwenty nauplii were incubated in 10 ml filtered (0.2 µm) seawater in each well of the six-well plates under continuous light, and fed daily with a 1:1 mixture of the unicellular algae, C. calcitrans and S. marinoi, at a concentration of 2 × 105 cells ml-1 21. Every second day, the water in each well was carefully replaced by filtered seawater at the respective temperature and salinity, and fresh food was added. The number of surviving nauplii, cyprids and settled juveniles in each experimental well were observed daily for 21 days using a dissecting microscope (Olympus SZX12). Preliminary trials confirmed that the short handling time of each six-well plate during observations did not cause any significant change in water temperature in any of the treatments. The resulting data were used to calculate: i) survival (% survivors in form of nauplii, cyprids or settled individuals at the end of the experiment relative to the initial number of nauplii), ii) naupliar duration (days from hatching until 50 % of the surviving nauplii had metamorphosed into cyprids), iii) successful metamorphosis to cyprids (% of the initial number of nauplii that metamorphosed into cyprids at the end of the experiment), and iv) overall settlement success (number of settled cyprids at the end of the experiment relative to the initial number of nauplii). We additionally calculated v) settlement of cyprids (number of successfully settled cyprids at the end of the experiment relative to metric iii).

title: Experiment II: Effect of temperature and salinity on survival of cyprids (Fig. 3b)

description: Experiment II - cypris settlementNewly released nauplius larvae were held at a density of 0.5 larvae ml-1 in filtered (0.2 µm) seawater in 20 l containers at 25°C and a salinity of 30 ("standard" culture conditions at the time of collection, (see Berntsson et al. for culture details 31)). Containers were gently aerated and provided with a 1:1 mixture of the unicellular algae, T. pseudonana and S. marinoi, at a concentration of 2 × 105 cells ml-1. Every third day, the water in each container was carefully replaced by filtered seawater and fresh food was added. When cyprids appeared in the cultures (usually after 6 to 7 days), the cultures were sieved (200 µm) and cyprids were collected. Ten cyprids were incubated under continuous light in 10 ml filtered (0.2 µm) seawater in each well of the six-well plates at the temperature and salinity combinations outlined above. The transition from initial to target temperature and salinity conditions was achieved gradually (2 salinity units h-1, 1°C h-1) to prevent acute shock to the cyprids. Every second day, the water in each well was carefully replaced with fresh filtered seawater at the respective temperature and salinity. Settlement and survival of cyprids were monitored daily over 26 days. From these data we calculated: i) survival and ii) settlement of cyprids.

title: Monthly and spatially resolved black carbon emission inventory of India: 2011

description: Black carbon (BC) emissions from India for the year 2011 are estimated to be 901.11 ± 151.56 Gg/yr based on a new ground-up, GIS-based inventory. The grid-based, spatially resolved emission inventory includes, in addition to conventional sources, emissions from kerosene lamps, forest fires, diesel-powered irrigation pumps and electricity generators at mobile towers. The emissions have been estimated at district level and were spatially distributed onto grids at a resolution of 40 × 40 km**2. The uncertainty in emissions has been estimated using a Monte Carlo simulation by considering the variability in activity data and emission factors. Monthly variation of BC emissions has also been estimated to account for the seasonal variability. To the total BC emissions, domestic fuels contributed most significantly (47 %), followed by industry (22 %), transport (17 %), open burning (12 %) and others (2 %). The spatial and seasonal resolution of the inventory will be useful for modeling BC transport in the atmosphere for air quality, global warming and other process-level studies that require greater temporal resolution than traditional inventories.

title: Inventory of glacial lakes in Austria (elevation &gt;1700m)

description: Glacial lakes constitute a substantial part of the legacy of vanishing mountain glaciation and act as water storage, sediment traps and sources of both natural hazards and leisure activities. For these reasons, they receive growing attention by scientists and society. However, while the evolution of glacial lakes has been studied intensively over timescales tied to remote sensing-based approaches, the longer-term perspective has been omitted due a lack of suitable data sources. We mapped and analysed the spatial distribution of glacial lakes in the Austrian Alps. Lakes in the inventory are located above 1.700 m a.s.l. and have a size greater than 1000 m². The lake inventory contains information on lake location, size, elevation, lake type (dam classification: dam material, damming process, dam form), lake formation period, glacial water supply, direct glacier contact.The lake mapping is based on orthoimages from 2015. Lake formation period corresponds to glacier inventory data of Austria (see Fischer et al. 2015, doi:10.1594/PANGAEA.844988).

title: (Table T1) Correlations between marker beds and drill holes for ODP Leg 171B sites

description: More than 50 discrete volcanic ash layers were recovered at the five drill sites of the Blake Nose depth transect (Leg 171B, western central Atlantic). The majority of these ash layers are intercalated with Eocene hemipelagic sediments with a pronounced frequency maximum in the upper Eocene. Several ash layers appear to be deposited from volcanic fallout with little or no indication of secondary remobilization. They provide excellent stratigraphic markers for a correlation of the Leg 171B drill sites. Other ash layers were probably redeposited from volcaniclastic-rich turbidity currents, but they still represent geologically instantaneous events that can be used in stratigraphic correlation between adjacent drill holes. Additional nonvolcanic marker beds, like the suspect late Eocene impact event layer, were included in our hole-to-hole correlations. Stratigraphic and downcore positions of marker beds were compiled and plotted against existing composite depth records that were constructed to guide high-resolution sampling. Comparison of our correlation with the spliced composite sections of each drill site reveals several minor and some major discrepancies. These may result from drilling distortion or missing sections, from the lack of unambiguous criteria for the synchronism of ash layers, or from the systematic exclusion of marker-bed data in the construction of the spliced record. Integration of both correlation approaches will help eliminate most of the observed discrepancies.
