Samoan-Passage

Learning about physical oceanography through dance

A visit of 5th and 6th graders from Escondido to the MOD labs and the Scripps campus this past Saturday marked the end of an unusual class setting: Learning about physical oceanography through dance. Over several sessions in the past few weeks, the students heard about ocean physics and ocean observations from physical oceanographers Larry Pratt and Gunnar Voet. In between the lessons, the students, together with their dance teacher Roxanne Rojas de Blanco, came up with dance moves to transform what they had just learned into a choreography. With a lot of creative energy the students danced ships in stormy seas and subsurface oceanographic moorings knocked over by strong currents.

During their Scripps visit, the students carried out tank experiments to learn about density in the ocean. To put into action what they had learned about moored observations, they tested an acoustic release. A walk across the campus ended on the Scripps pier with seal, leopard shark and sting ray sightings.

Many thanks to Roxanne at A Step Beyond and our colleague Larry Pratt from WHOI for organizing this workshop, and to the National Science Foundation for financial support through our Samoan Passage research project!

An oldie but goodie from the Samoan Passage project

This video was made when Matthew was at APL/UW, but describes the science and adventure behind the Samoan Passage project pretty well.

A documentary special about a team of oceanographers chasing down 800 foot tall SUPERWAVES-- waves taller than sky scrapers-- that build and crest 15 thousand feet deep beneath the surface of the sea. These SUPERWAVES, also called "internal waves" are strong enough to push a full size submarine to the bottom of the seafloor and move enough water to affect the earth's climate.
