mzCloud

Advanced mass spectral database

Subject(s)
Content type(s)
Country
mzCloud is an extensively curated database of high-resolution tandem mass spectra that are arranged into spectral trees. MS/MS and multi-stage MSn spectra were acquired at various collision energies, precursor m/z, and isolation widths using Collision-induced dissociation (CID) and Higher-energy collisional dissociation (HCD). Each raw mass spectrum was filtered and recalibrated giving rise to additional filtered and recalibrated spectral trees that are fully searchable. Besides the experimental and processed data, each database record contains the compound name with synonyms, the chemical structure, computationally and manually annotated fragments (peaks), identified adducts and multiply charged ions, molecular formulas, predicted precursor structures, detailed experimental information, peak accuracies, mass resolution, InChi, InChiKey, and other identifiers. mzCloud is a fully searchable library that allows spectra searches, tree searches, structure and substructure searches, monoisotopic mass searches, peak (m/z) searches, precursor searches, and name searches. mzCloud is free and available for public use online.

The National Pollutant Release Inventory (NPRI) is Canada's legislated, publicly accessible inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. It is a key resource for: identifying pollution prevention priorities; supporting the assessment and risk management of chemicals, and air quality modelling; helping develop targeted regulations for reducing releases of toxic substances and air pollutants; encouraging actions to reduce the release of pollutants into the environment; and improving public understanding. The NPRI comprises: Information reported by facilities and published by Environment and Climate Change Canada under the authority of Sections 46 – 50 of the Canadian Environmental Protection Act, 1999 (CEPA 1999); and Comprehensive emission summaries and trends for key air pollutants, based on facility-reported data and emission estimates for other sources such as motor vehicles, residential heating, forest fires and agriculture. For the latest reporting year, 7,708 facilities reported to the NPRI on more than 300 listed substances. Comprehensive air pollutant emission summaries and trends were compiled by Environment and Climate Change Canada for criteria air contaminants (the main pollutants contributing to smog, acid rain and/or poor air quality), selected heavy metals and persistent organic pollutants.

>>>>!!!<<< NEPTUNE Canada is now part of Ocean Networks Canada and this website is being phased out. Please visit us on our new website at oceannetworks.ca >>>!!!<<< NEPTUNE Canada, the North-East Pacific Time-series Undersea Networked Experiments, is the world's first regional scale cabled deep ocean observing network. It consists of an 800km network of electro‐optic cable laid on the seabed over the northern Juan de Fuca tectonic plate, off the coast of British Columbia. This tectonic plate serves as an exceptional natural laboratory for ocean observation and experiments. NEPTUNE Canada instruments yield continuous real‐time data and imagery from the ocean surface to beneath the seafloor, and from the coast to the deep sea. They respond to events such as earthquakes, tsunamis, fish migrations, plankton blooms, storms and volcanic eruptions. NEPTUNE Canada offers a unique and exciting approach to ocean science.
