AIRS Research Areas
Graduate and undergraduate students who wish to study the intersection of atmospheric sciences, oceanography, and engineering at the Applied Physics Laboratory may work with AIRS advisors who have joint apointments in UW academic departments. More >>
Graduate student Michael Schwendeman worked with advisor Jim Thomson to track and measure breaking waves in the North Pacific during an expedition to Ocean Station Papa. Mike's blog chronicled the research cruise.
What We Do
The Air-Sea Interaction and Remote Sensing (AIRS) Department is a diverse group of scientists, engineers, technical support staff, and students that conducts research focused on the air-sea interface by using a wide variety of remote sensing techniques.
Our interests range from the global scale of climate change and ocean circulation to the smallest scales of the physics of air-sea heat and gas exchange.
Our remote sensing tools also span a wide range of scalesfrom satellite remote sensing, to field experiments using surface and airborne platforms, and to laboratory experiments in wave tanks. Remote sensing instruments used include electro-optical sensors (microwave, infrared, and laser) and acoustic sensors (sonars and hydrophones).

Sharks as Oceanographic Research Platforms
Shark swimming paths and feeding behaviors are giving Peter Gaube and his colleagues some new insights to the annual phytoplankton bloom cycle in the North Atlantic. More >>
SWIFT Tests in Arctic Waters
Graduate student researcher Seth Zippel tests SWIFT (Surface Wave Instrument Float with Tracking) performance in the Arctic in advance of planned missions to be conducted in summer 2014 during the Marginal Ice Zone experiments. More >>
Depth, or bathymetry, is a key variable to understand how to navigate safely in a shallow water environment and it is also key to predicting the currents and waves. DARLA will help determine the extent to which data assimilation models, that are initialized and constrained with remote sensing and in situ measurements, can infer bathymetry. More >>
Marginal Ice Zone Program
An integrated program of observations and numerical simulations will focus on understanding iceoceanatmosphere dynamics in and around the MIZ, with particular emphasis on quantifying changes associated with decreasing ice cover. The MIZ measurement program will employ a novel mix of autonomous technologies (ice-based instrumentation, floats, drifters, and gliders) to characterize the processes that govern Beaufort Sea MIZ evolution from initial breakup and MIZ formation though the course of the summertime sea ice retreat.

Sea State and Boundary Layer Physics of the Emerging Arctic Ocean
This ONR Departmental Research Initiative is in response to the observed decline in Arctic sea ice extent. The U.S. Navy has a renewed interest in understanding and predicting the environment in this region, including a desire to forecast the presence or absence of sea ice at a variety of lead times.

Turbulence Generated by Tides in the Canal de Chacao, Chile
At a proposed tidal energy conversion site in southern Chile, APL-UW researchers measured the magnitude and scales of turbulence to aid the design of turbines for the site and to understand the fundamental dynamics of flows through the channel. More >>

Atlantic Ocean’s slowdown tied to changes in the Southern Hemisphere
UW News and Information, Hannah Hickey

The ocean circulation that is responsible for England’s mild climate appears to be slowing down. The shift is not sudden or dramatic, as in the 2004 sci-fi movie “The Day After Tomorrow,” but it is a real effect that has consequences for the climates of eastern North America and Western Europe.
Why Might Sharks Gravitate to the Hurricanes of the Ocean?

Around Cape Hatteras, North Carolina, the Gulf Stream veers east, flowing away from the coastline of the United States and out into the Atlantic Ocean. Away from the stabilizing influence of the continent, the powerful current revels in its new freedom, spawning large circulating masses of water called eddies that scientists describe as the hurricanes of the ocean.
Now, in preliminary research, scientists are trying to figure out how great white sharks may use the spinning features.
