Experimental data from a study evaluating the electromagnetic wave absorption properties of a talc/NiTiO3 composite material. The dataset includes measurements of reflection loss, with a maximum of -11.94 dB at 6.85 mm thickness, and surface area changes from 2.51 m²/g to 79.09 m²/g after calcination at 650°C. It was authored by Wen-Li Qin and published via Dryad in 2020.
Encompassing computational results from density functional theory (DFT) calculations investigating perylene molecules encapsulated in carbon nanotubes (CNTs). The data was generated by author Yuya Nagasawa and last updated in June 2020. It examines metastable molecular conformations and electronic structures for perylene within semiconducting (19,0) and metallic (11,11) CNTs.
Comprising experimental data on synthesized diketopyrrolopyrrole-based polymers with polydimethylsiloxane (PDMS) side chains. The polymers were evaluated for their solubility, thin-film crystallinity, and performance in organic field-effect transistors, comparing different PDMS content and substitution patterns.
Model results from a 2019 study published in the Journal of Geophysical Research: Atmospheres by F. Comola et al. simulate preferential deposition of snow and dust particles over complex terrain. The dataset contains 2D arrays of deposition values (kg/m²) for each surface node in a Cartesian grid, generated using a coupled large eddy simulation and Lagrangian stochastic model. The research aimed to reconcile contradictory findings on deposition maxima and minima by analyzing the roles of particle inertia, flow advection, and gravity.
Three GPS beacons were deployed on Antarctic sea ice floes in July 2017 to measure drift. The instruments recorded location data at 4-hour intervals, with tracks lasting from several weeks to nearly five months. The dataset contains the GPS coordinates, dates, and times for each unit, submitted by the organization AU_AADC.
Crystal structure and functional characterization of an isoaspartyl dipeptidase (CpsIadA) from Colwellia psychrerythraea strain 34H. The dataset includes structures for both ligand-free and ligand-complexed forms at 1.85-Ã… and 2.33-Ã… resolution, respectively. It was produced by AMD_KOPRI and published in 2017.
March 19-22, 2017 measurements of Dall sheep hoof sinking depths in snow tracks, alongside snow depth, hardness, and density from adjacent snow pits. Data was collected at sites on Jaeger Mesa in the Wrangell Mountains, Alaska, and includes estimated sheep age classes and track site coordinates. The dataset is provided by the ORNL_CLOUD organization.
A 2015 global simulation of black carbon aerosol concentrations and daily deposition from the FLEXPART Lagrangian particle dispersion model. The dataset provides daily values on a 1x1 degree grid, created by the GES_DISC organization. It models atmospheric transport and deposition processes for this climate-relevant pollutant.
Crystal structures of two forms of the UbiX enzyme from the psychrophilic bacterium Colwellia psychrerythraea, including an FMN-bound wild type and an FMN-unbound mutant. The dataset provides atomic-level structural data revealing novel FMN-binding domain architecture and FMN-induced conformational changes in the C-terminal loop. The structural data was produced by the AMD_KOPRI organization and published in 2015.
A 2015 dataset from the Australian Antarctic Data Centre contains raw and processed logs, spreadsheets, and R scripts from respiration and PAM (Pulse-Amplitude-Modulation) chamber experiments. It includes measurements of dissolved oxygen, photosynthetically active radiation (PAR), temperature, salinity, and chlorophyll fluorescence for control and acidified treatments. The collection features raw sensor logs, cleaned Excel files, and rapid light curve data for physiological analysis.
Ambient light and seawater temperature measurements were collected from the seafloor during a controlled ocean acidification experiment near Casey Station, Antarctica. The Australian Antarctic Data Centre managed this data, which captures conditions from the austral summer of 2014/15. Sensors were deployed inside experimental chambers, open plots, and around the site to monitor environmental variables.
Matlab files contain 10-second interval measurements of wind, temperature, humidity, and snow particles from two instrument masts deployed on Antarctic sea ice during the 2012 SIPEX II voyage. Data was collected by the Australian Antarctic Data Centre using Campbell Scientific CR1000 dataloggers and specific sensor models from RM Young and Rotronics. The dataset covers at least three ice stations from October 2012.
Research from 2011 investigates the Southern McMurdo Ice Shelf's structure, composition, and motion. The project uses surface mapping from aerial photographs and satellite imagery, ground-penetrating radar surveys, GPS stake monitoring, and ice core analysis. It was conducted by SCIOPS to develop a model for sediment entrainment and ice shelf moraine formation.
1335 ocean profiles collected from September 2006 to July 2008 by the Woods Hole Oceanographic Institution. The Ice Tethered Profiler (ITP) was deployed on 9/4/2006 and recorded two daily profiles between 9 and 760 meters depth at 0000 and 0600 UTC. GPS locations, buoy temperature, and battery voltage status were recorded hourly by the surface package.
Data from 2009 characterizes the microstructure of ice cores from Siple Dome A between depths of 640 meters and 790 meters. The dataset likely contains pole figures and misorientation angle distributions for polycrystalline ice grains. It was provided by AMD_USAPDC and focuses on both a-axis and c-axis orientations.
1569 ocean profiles were collected from August 2007 to October 2009 by an Ice Tethered Profiler operated by SCIOPS. The instrument performed two daily profiles between 7 and 760 meters depth, recording temperature and location data while drifting with the Beaufort Gyre. Data transmission was reliable for the first 707 profiles, with additional data recovered upon instrument retrieval.
Methylthymol blue adsorbed onto Dowex resin beads forms a novel binding phase for diffusive gradients in thin-film sampling of Cu(II). The technique, developed by the Australian Antarctic Data Centre, enables detection at microgram-per-liter concentrations in test solutions. This metadata record documents the project's development phase, culminating in a 2008 publication.
WHOI Ice Tethered Profiler #4 collected 698 profiles of ocean salinity and temperature over 349 days. Deployed on September 3, 2006, it was the first ITP configured for a standard schedule of two daily profiles between 7 and 760 meters depth. The instrument, operated by SCIOPS, transmitted daily status data and was recovered for direct data retrieval.
From March 21 to June 7, 2007, the U.S. Army Corps of Engineers collected wave and current data in Kuhio Bay, Hilo, Hawaii. Data were gathered at three fixed locations using bottom-mounted Acoustic Doppler Current Profilers (ADCPs). The dataset is archived by NOAA's National Centers for Environmental Information (NCEI).
From 1956 to 2005, bathymetric surveys of South San Francisco Bay were compared to study sediment deposition and erosion. The analysis identified an erosional period from 1956 to 1983 and a depositional period from 1983 to 2005, with net changes varying by subregion. The dataset was summarized by the USGS.
