An APL-UW research team has developed an ultrasound system capable of non-invasive, real-time, image-guided repositioning of kidney stones. During presentations to the urology community at the urological association's annual meeting in May 2013, the team and the system garnered interest and praise. Webcasts of their presentations are available temporarily.

Investigators have just completed a series of experiments at the mouth of the Columbia River, where they collected data using drifting and airborne platforms. DARLA's remote sensing data will be used to drive representations of the wave, circulation, and bathymetry fields in complex near-shore environments.

From 22–26 April, APL-UW researchers, along with UW Oceanography department graduate students and educators from the Pacific Northwest, will cruise aboard the R/V Thompson on a mission of buoy deployment, Washington shelf science experiments, learning, and gaining experience at sea.

As arctic sea ice transitions from a multi-year to a more seasonal ice pack, buoys deployed by the International Arctic Buoy Programme have required improvements to better survive the seasonal ice regime. The recent and dramatic environmental changes have pushed scientists and engineers to improve the platforms and sensors rapidly.

Scientists are studying the impact of reduced sea ice and changes in ocean–ice–atmosphere interaction in the Beaufort and Chukchi seas region. A summertime marginal ice zone is a long-standing feature in the shallow Bering and Chukchi seas, but its expansion to the deep Beaufort Sea is a relatively new phenomena.

APL-UW's Oceanographer Trina Litchendorf and Senior Engineer Andy Stewart are mentoring the University of Washington's ROV Team. Learn about this dedicated and energetic group of undergraduates—what they've done, and where they're heading next.

The Office of Naval Research has launched an initiative in response to the decline in Arctic sea ice extent. Collaborative research seeks to understand and predict the environment in this region, including a desire to forecast the presence or absence of sea ice at a variety of lead times.
