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.

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
