2018 research from AMD_KOPRI evaluates the skin protection efficacy of the material KSF0031 and related compounds. The dataset examines the effect on skin cells and investigates the underlying mechanisms of action. It was last updated in October 2018.
NOAA_NCEI Accession 0195411 contains nitrogen and carbon content and stable isotope ratios from sediment core, surface sediment, and suspended particle samples. Data was collected in the Fowl River Watershed at four priority marsh spits and one downstream reference site. Analysis was performed by the U.C. Davis Stable Isotope Facility using continuous flow isotope ratio mass spectrometry.
Concentrations of individual sterols and n-alkanes were measured in the seawater of Kongsfjorden, Svalbard. The dataset was collected by the Korea Polar Research Institute (AMD_KOPRI) during April 2018, focusing on a specific Arctic fjord environment.
Historical data from a remediation project covers environmental sampling from 2009 to 2016. The dataset includes measurements for hydrocarbons, nutrients, volatile compounds, and soil properties from sites including Macquarie Island, Casey Station, Davis Station, and Lake Dingle. It was submitted by the Australian Antarctic Data Centre (AU_AADC) in March 2017.
Sediment core data from the northern Gulf of Mexico collected during the R/V Weatherbird cruise WB-0814 in August 2014. The dataset includes gas chromatography-mass spectrometry characterization of hydrocarbons, bulk density and porewater measurements, short-lived radioisotope data, sediment texture and composition, and core photographs. Data were collected and processed by NOAA NCEI from samples sectioned at 2mm and 5mm intervals.
From February 2013 to June 2014, grab samples of sediments were collected from RV Donald W Pritchard in Hempstead Bay, New York. The dataset likely contains measurements of sewage-derived compounds, including Quaternary Ammonium Compounds (QACs) and other personal care products. The data was collected by NOAA_NCEI approximately 100 days to 20 months after Superstorm Sandy.
A 2012 classified geospatial map covering 26 EU member states, Norway, Switzerland, and non-EU Balkan countries. The map provides landslide susceptibility assessments at a 1 km x 1 km resolution, developed by SCIOPS using over 100,000 georeferenced landslide events for model calibration. It classifies terrain into five susceptibility levels based on landslide frequency across seven climato-physiographic regions.
Discrete sample and profile data collected from the LAURENCE M. GOULD research vessel in the Gulf of Guinea, South Atlantic Ocean, and Southern Oceans from March 23, 2006, to November 2, 2010. These data include DELTA CARBON-13, DELTA CARBON-14, SALINITY, and WATER TEMPERATURE, collected using CTD and bottle instruments. The data were collected by researchers from Lawrence Livermore National Laboratory, NOAA, and the University of Washington as part of the Drake Passage Radiocarbon Data set.
Marine sediment cores collected near Davis Station, Antarctica, during the summer of 2009/10. The dataset contains concentrations of water-extractable nutrients, including anions and ammonium, analyzed using ion chromatography and colorimetry. The data was produced by the Australian Antarctic Data Centre (AU_AADC) and last updated in March 2010.
MERIS data from ESA's ENVISAT satellite provides daily maps of chlorophyll concentration in the North Sea. The product was developed by DLR-DFD and the GKSS Institute for Coastal Research within the MAPP project. Data was pre-processed by DFD and last updated in March 2010.
Daily maps of chlorophyll concentration in Lake Constance derived from MERIS satellite imagery. The product was developed by DLR-DFD and the GKSS Research Centre Geesthacht within the MAPP project, with data pre-processed by DLR-DFD. The dataset was last updated in March 2010.
2002 to 2012 data from the Medium Resolution Imaging Spectrometer (MERIS) on ESA's ENVISAT satellite. The dataset provides 10-day aggregated maps of chlorophyll concentration for Lake Constance, developed by DLR-DFD and the GKSS Research Centre's Institute for Coastal Research. It was produced under the MAPP project for regional water quality monitoring.
Ten-day maps of chlorophyll concentration in the North Sea derived from spectral data. The product was developed by DLR-DFD and the Institute for Coastal Research at GKSS Research Centre Geesthacht as part of the MAPP project. Data was collected by the MERIS instrument on ESA's ENVISAT satellite, with the last recorded update in March 2010.
MERIS satellite data provides monthly maps of chlorophyll concentration in the North Sea at a 300-meter spatial resolution across 15 spectral bands. The German Aerospace Center (DLR-DFD) and the GKSS Research Centre's Institute for Coastal Research processed this data as part of the MAPP project. This dataset was last updated in February 2010.
