Shipping companies can route ships more safely and efficiently. Ocean search-and-rescue can operate more effectively. Meteorologists and climatologists now have a tool to provide long-range weather prediction more accurately. Navies too can perform more accurate anti-submarine surveillance. And environmental managers now have a mechanism to track pollution, algal blooms, or emergent situations such as oil spills. And, this is all due to a unique three-dimensional ocean model that has been developed by Rosenstiel School researchers in collaboration with scientists at the Naval Research Laboratory.
Featured in the March issue of Oceanography, the HYbrid Coordinate Ocean Model (HYCOM) is the critical part of data assimilative systems at the Naval Research Laboratory and at NOAA’s National Center for Environmental Prediction. The Navy will tap the velocities, temperature, and salinities of the HYCOM prediction system to force smaller models that provide even higher resolution that can account for things like rivers, tides, etc. in real-time for anywhere in the world. NOAA’s new Real-Time Ocean Forecast System will provide mariners with “nowcasts” and five-day forecasts for the entire North Atlantic Ocean. While other ocean models have been developed in the past, HYCOM is unique not only because it provides three-dimensional, global data that is of fine enough resolution to factor in the real-time displacements in currents caused by eddies, but also because of its flexibility in modeling both coastal and deep ocean regions (http://www.hycom.org). This enhanced understanding of the ocean offers invaluable applications.
“While a computer model may sound rather abstract to non-scientists, it’s exactly what can help clarify forecasting and minimize or prevent impacts from natural hazards on the seas,” said Dr. Eric Chassignet, principal investigator and a Rosenstiel School professor in meteorology and physical oceanography. Chassignet also just published a related book, titled Ocean Weather Forecasting: An Integrated View of Oceanography, which is now available.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
