Study of Air-Sea Fluxes and Atmospheric River Intensity (SAFARI)

In July 2023, the Office of Naval Research (ONR) partnered with the 144th Airlift Squadron of the Alaska Air National Guard to deploy five different types of weather buoys across more than 1,000 nautical miles of the Arctic Ocean. Such deployments are critical for maintaining the Arctic Observing Network (AON), which provides observations for weather and ice forecasting and related research. “Understanding ocean and weather conditions in the Arctic region is crucial to ensuring safe, effective naval operations in this challenging part of the world,” said Chief of Naval Research Rear Adm. Kurt Rothenhaus. “Exercises like this buoy drop are a testament to the value of strong international scientific partnerships and collaboration, in order to share knowledge, resources and insights.” The buoy air deployment supported the International Arctic Buoy Programme (IABP), a collaborative program comprising more than 32 different research and operational institutions from 10 different countries and four international agencies — including the International Cooperative Engagement Program for Polar Research (ICE-PPR), European Meteorological Network, World Climate Research Programme and World Meteorological Organization.

The Office of Naval Research (ONR) sponsored a project at Virginia Tech University nearly 20 years ago that is now growing in influence across the world for measuring aerospace and aeronautical acoustics. Since noise reverberates against solid surfaces, such as the walls of a wind tunnel where acoustical testing takes place, collecting accurate sound data had been nearly impossible at the time. Researchers were also struggling to discern the sound of the wind tunnel’s air flow from the noise of the object traveling through it. After learning about some experiments on Kevlar as a wind screen, William Devenport, an engineering professor and director of Virginia Tech’s Stability Wind Tunnel, said he and a colleague wrote a proposal to then-ONR program officer Ron Joslin to try adding Kevlar to their wind tunnel walls. Devenport submitted the original grant proposal (N00014–04–1–04933) through the FY 2004 Defense University Research Instrumentation Program (DURIP) for alterations to Virginia Tech’s existing Stability Wind Tunnel that would allow it to measure flow-induced noise of relevance to Navy applications.

A dynamic era in naval oceanography recently ended as the iconic Floating Instrument Platform — popularly known as FLIP — was officially retired from service. Built in 1962 with funding from the Office of Naval Research (ONR), FLIP helped generations of scientists and oceanographers better understand the mysteries of the sea, including internal waves, air-sea interaction and long-range sound propagation. Sadly, age and exorbitant life-extension costs resulted in the platform being disestablished. On Aug. 3, a solemn gathering of well-wishers watched as FLIP was towed, at sunset, to a dismantling and recycling facility. Last month, a formal good-bye ceremony was hosted by the Marine Physical Laboratory at the University of California, San Diego (UCSD). Though retired, FLIP will live on at Scripps. One of its booms (crane-like arms for suspending instruments) will be installed on the Scripps research pier in La Jolla and used to deploy instruments. Also, artifacts from the platform will be displayed in a permanent exhibit at Scripps’ Birch Aquarium.

Extraordinarily rugged with a melting temperature of several thousand degrees Fahrenheit. That describes the results of research into new ceramic materials sponsored by the Office of Naval Research (ONR) and recently published in the Journal Nature. A research team, led by ONR’s Principal Investigator, Dr. Stefano Curtarolo, Duke University, developed a computational method for creating new types of ceramics using transition metals – carbonitrides or borides – through a process called Disordered Enthalpy-Entropy Descriptor (DEED). The applications are endless, said Dr. Eric Wuchina, a research materials engineer who was the program officer with ONR’s Sea Warfare and Weapons department when Curtarolo’s research team was awarded the Multidisciplinary University Research Initiative (MURI). According to Wuchina, the variety of new compositions could create potentially millions of new materials.

A research project from the Office of Naval Research (ONR) Global is providing valuable information about the effects of melting glaciers in Patagonia that feed into coastal fjords, transporting sediments, freshwater and nutrients. Dr. Chris Konek, science director at ONR Global in Chile, said the research will help the Department of the Navy (DoN) understand the effects of a changing climate on the coastal environment. “That’s the kind of the thing the Marines need to be able to handle,” he said. “It’s basic research and so it will help provide a fundamental understanding of this aspect of coastal systems where you can expect more things like this to happen in the future – more glacial melting as opposed to less.” Cristian Escauriaza, professor, Pontificia Universidad Católica de Chile, is the principal investigator along with his university colleague, Megan Williams. They are working with the Filantropía Cortés-Solari, a conservation organization that owns and manages the Melimoyu Elemental Reserve in northern Patagonia. Patagonia is largely remote with a diverse ecosystem and a rich array of wildlife, including penguins and blue whales. Konek said ONR Global is interested in Escauriaza’s project for its potential to inform what’s happening to that ecosystem, which can also help inform what’s happening to other coastal regions experiencing the same challenges.
