Total carbon, total inorganic carbon and total organic carbon content in standard shipboard samples from IODP Hole 357-M0071A

Samples were not collected and handled in a way to minimize carbon contamination and are likely overestimates of true values. TC data are averages of 2-3 replicates with standard deviation of the measurement and the coefficient of variance of the measurements. TIC was determined by subtraction of TOC from TC.

Alkalinity, pH and delta13C values for fluid samples from IODP Hole 357-M0068A

Reported pH was determined from the average value of the sensor package pH meter mounted on the rock drills.

Pre-compiled metrics data sets, links to aggregated statistics files in CSV format

Martin G Schultz, Sabine Schröder, Olga Lyapina & Owen R Cooper
Errata: Due to a coding error, monthly files with "dma8epax" statistics were wrongly aggregated. This concerns all gridded files of this metric as well as the monthly aggregated csv files. All erroneous files were replaced with corrected versions on Jan, 16th, 2018. Each updated file contains a version label "1.1" and a brief description of the error. If you have made use of previous TOAR data files with the "dma8epax" metric, please exchange your data...

Increased temperature, rather than elevated CO2, modulates the carbon assimilation of the Arctic kelps Saccharina latissima and Laminaria solidungula, supplement to: Iñiguez, Concepcion; Carmona, Raquel; Lorenzo, M Rosario; Niell, F Xavier; Wiencke, Christian; Gordillo, Francisco J L (2016): Increased temperature, rather than elevated CO2, modulates the carbon assimilation of the Arctic kelps Saccharina latissima and Laminaria solidungula. Marine Biology, 163(12), 18 pp

Concepcion Iñiguez, Raquel Carmona, M Rosario Lorenzo, F Xavier Niell, Christian Wiencke & Francisco J L Gordillo
Ocean acidification and warming are affecting with special intensity the Arctic Ocean. Arctic coastal ecosystems are dominated by kelp forests with a high biomass production, which are expected to be directly affected by the increases in CO2 and temperature. This study presents the different physiological responses of the Arctic kelps Saccharina latissima and Laminaria solidungula from Kongsfjorden (Svalbard) cultured at 4 and 9 °C in combination with current (390 ppm) and increased (1200 ppm) levels...

Grain Structure, Grain-averaged Lattice Strains, and Macro-scale Strain Data for Superelastic Nickel-Titanium Shape Memory Alloy Polycrystal Loaded in Tension

Harshad M. Paranjape, Partha P. Paul, Hemant Sharma, Peter Kenesei, Jun-Sang Park, T.W. Duerig, L. Catherine Brinson & Aaron P. Stebner
A cylindrical dog bone specimen from NiTi shape memory alloy is loaded in tension at room temperature for eleven cycles. Maximum stress in each cycle is approximately 220 MPa. The experiment is performed in-situ at Sector 1, beam line 1ID-E of Advanced Photon Source, Argonne National Laboratory. Using far-field high-energy diffraction microscopy technique, grain centroids, grain-averaged lattice strain tensor, grain volume, and grain-averaged crystal orientation are obtained at the start of the first cycle and...

Dataset for A Blocked Linear Method for Optimizing Large Parameter Sets in Variational Monte Carlo

Luning Zhao & Eric Neuscamman
We present a modification to variational Monte Carlo’s linear method optimization scheme that addresses a critical memory bottleneck while maintaining compatibility with both the traditional ground state variational principle and our recently-introduced variational principle for excited states. For wave function ansatzes with tens of thou- sands of variables, our modification reduces the required memory per parallel process from tens of gigabytes to hundreds of megabytes, making the methodology a much bet- ter fit for modern...

Characterizing the Unifying Thread in High Temperature Superconductors Using Realistic Simulations

Awadhesh Narayan, Brian Busemeyer & Lucas K. Wagner
This is a dataset collecting high accuracy quantum Monte Carlo (QMC) results for pnictide and cuprate compounds, some of which are high temperature superconductors. Our trial wavefunction consists of a Slater determinant augmented by a Jastrow factor. We construct the Slater determinant using orbitals from density functional theory (DFT). Our DFT calculations are done using the CRYSTAL package, with the PBE0 functional. We use Burkatzki-Filippi-Dolg pseudopotentials to replace the core electrons. We then use the...

Solute transport database in Mg using ab initio and exact diffusion theory

Ravi Agarwal & Dallas R. Trinkle
This dataset demonstrate the improved solute transport in hcp Mg through exact diffusion theory:Green function approach. We report the database of 61 solutes consisting of solute diffusivity and solute drag ratio. We also report the results from previously used approximate models of diffusion namely 8-frequency and 13-frequency models. The parameters needed for the diffusion models i.e. binding energy, migration barrier and attempt frequency are obtained through density functional theory calculations

Chemical vapor deposition of monolayer MoS2 directly on ultrathin Al2O3 for low-power electronics

Hadallia Bergeron, Vinod K. Sangwan, Julian J. McMorrow, Gavin P. Campbell, Itamar Balla, Xiaolong Liu, Michael J. Bedzyk, Tobin J. Marks & Mark C. Hersam
This data corresponds to the characterization of a transfer-free ultrathin heterostructure of a 2D semiconductor and high-k dielectric, and the resulting field-effect transistors. Monolayer MoS2 was grown directly via chemical vapor deposition on 20 nm of amorphous alumina deposited via atomic layer deposition on a silicon substrate. This method of integrating 2D MoS2 with a high-k dielectric results in superior performance in low-power electronics figures of merit. DOI: doi.org/10.1063/1.4975064

Pre-compiled metrics data sets, links to yearly statistics files in CSV format

Martin G Schultz, Sabine Schröder, Olga Lyapina & Owen R Cooper
Errata: On Dec 2nd, 2018, several yearly statistics files were replaced with new versions to correct an inconsistency related to the computation of the "dma8epax" statistics. As written in Schultz et al. (2017) [https://doi.org/10.1525/elementa.244], Supplement 1, Table 6: "When the aggregation period is “seasonal”, “summer”, or “annual”, the 4th highest daily 8-hour maximum of the aggregation period will be computed.". The data values for these aggregation periods are correct, however, the header information in the...

Tropospheric Ozone Assessment Report, link to software tools

Martin G Schultz, Sabine Schröder, Olga Lyapina & Owen R Cooper
The programs in this distribution comprise a collection of python tools that have been used in the preparation and quality control of surface ozone datasets that were used in the first Tropospheric Ozone Assessment Report (TOAR). Many of these programs will require access to the TOAR database with hourly observations, so that you will not be able to run these tools. Other programs (for example in the statistics or cdm directories) can be adapted for...
