Radio Interviews with Dr. Musgrave

In 2002 and 2003, interviews with Dr. David L. Musgrave of the University of Alaska's Institute of Marine Science were broadcast on KUAC. We have obtained electronic versions of the interviews from KUAC 89.9 FM and placed them online for your listening pleasure. To listen to these interviews and view some additional materials on the subjects Dr. Musgrave discusses, follow the links below. In order to play these files you must have Real Audio and Windows Media Player.

2/6/02 Sitka Eddy: Dr. Dave Musgrave and Steve Reifenstuhl discuss the implications of the Sitka Eddy on the productivity of the Gulf of Alaska.

3/28/02 The SALMON Project
: Dr. Musgrave introduces a new University of Alaska initiative called the SALMON Project.

4/4/02 The "Rio Royer", a.k.a. The Alaska Coastal Current: The impacts of the tremendous amount of freshwater discharge into the Gulf of Alaska are discussed.

4/18/02 Large Scale Atmosphere-Ocean Interactions: The effects of the prevailing winds on the circulation of the Gulf of Alaska, as well as El Niño and the Aleutian low are discussed.

4/25/02 The Pacific Decadal Oscillation
: An oscillating climate pattern known as the Pacific Decadal Oscillation (PDO) is introduced.

5/2/02 GLOBEC: Some of the preliminary results of the Global Ocean Ecosystem Dynamics (GLOBEC) monitoring program in the Gulf of Alaska are discussed.

5/9/02 Ocean Modeling: Using the 1989 Exxon Valdez oil spill disaster as an example, Dr. Musgrave explains how ocean circulation models in conjunction with observations can be used to predict the dispersal of hazardous materials.

5/16/02 Boxes of Water: Dave Musgrave explains the theory behind how ocean circulation models work. Starting with the equations that form their basis and moving on to how these equations are solved on computers such as those at the Arctic Region Supercomputing Center.

5/23/02 The Coriolis Force: A spinning merry-go-round is used to explain an apparent force called the Coriolis Force, often confused with the forces that impart rotation as a toilet bowl drains.

6/6/02 Angular momentum and Vorticity in the ocean: Dave Musgrave talks about stratified density layers in the ocean that move as water columns due to angular momentum.

6/13/02 Ocean Waves Being Mechanisms for Stratified Layer Mixing: Strong winds create surface waves on the ocean which act as a mechanism for turbulant mixing of stratified layers.

6/27/02 Studying the ocean from deep in the interior of Alaska: Research in Oceanography does not require you to be present on the coast. Resources found in a university setting privide essential tools for research

7/11/02 Dr. Dave Musgrave discusses the choices he made thoughout his life that led to his career in physical oceanography research:

7/25/02 The Russel Fjord is blocked by glacial moraine: Fresh water is filling in behind glacial moraine in Russell fjord preventing fresh water from flowing into the ocean

8/1/02 Why is Scandinavia so warm?: The Scandinavian region is relatively equal in latitude to the Alaska region but stays comparativly warmer to the Alaska climate.

8/22/02 Global circulation by the conveyor belt: Ocean currents circulate over the entire globe on larger time scales, and have the ability to influence distant climates.

8/29/02 The Ocean's many seas: The Oceans are made up of many different seas that are all connected, unlike the continents.

9/5/02 The sea surrounding Alaska: Dr. Dave Musgrave talks about the connectivity of the Pacific ocean, Bering sea, and Arctic Ocean surrounding Alaska.

9/12/02 The Ocean bottom: The ocean bottom has a surface similiar to land, but also very different; tall seamounts, deep sea trenches are just a few.

9/19/02 CODAR: Oceanographers use a type of RADAR to measure surface velocity of large area of water.

9/26/02 Measuring currents across Cook Inlet: Using CODAR (a type of radar used to measure surface currents of a large body of water) oceanographers can gain detailed information about Tides that dominate the 'background' current flow in Cook Inlet.

10/03/02 Internal and Surface Ocean Waves: Surface and Internal waves are caused by the interaction of fluid layers of different densities. Dave talks about the interactions at the ocean's surface, and below the suraface that give rise to various ocean waves.

10/17/02 Dave goes to China: Dave talks about attending the North Pacific Marine Organization(PICES) in China.

10/31/02 PICES meeting: The North Pacific Ocean still harbors plenty of secrets for scientists to explore. One way to share information is through the annual PICES meeting. UAF Oceanographer Dave Musgrave just got back from the forum, held in China this year.

11/7/02 underwater volcanoes: Scientists have studied volcanoes for years, trying to understand the role they play in the earth's geology. John Delaney teaches at the University of Washington where he studies underwater volcanoes.

11/14/02 Prince William Sound: The circulation of water through Prince William Sound is heavily influenced by influences like topography and the depth of the water in the Gulf of Alaska. UAF Oceanographer Dave Musgrave says it causes from top to bottom and left to right.

12/5/02 CODAR in real time: Scientists are setting up a Coastal Ocean Radar to map currents and other circulation patterns in the North Pacific Ocean. UAF Oceanographer Dave Musgrave says these remote observations will expand the amount of information scientists can compile.

12/12/02 remote sensing challenges: Scientists are increasingly reliant on a system of remote sensors to collect data. UAF Oceanographer Dave Musgrave talks about the challenges of setting up these stations.

1/9/03 The earth has a predictable tide schedule featuring two a day. As Oceanographer Dave Musgrave explains, it's a result of the geometry between the earth, the sun and the moon.

1/16/03 Scientists at the University of Massachusetts are developing a line of Autonomous Underwater Vehicles that will revolutionize oceanography. Technical Director Lew Goodman says it gathers information in an environment formerly off limits to humans.

1/30/03 The famous waves of Hawaii aren't just an accident. As UAF Oceanographer Dave Musgrave explains, there's a scientific equation behind the surf.

2/13/03 The motion of the ocean is ruled by currents and tides. UAF Oceanographer Dave Musgrave describes a unique water movement called a tidal rip in Cook Inlet.
