Wavechasers and the Samoan Passage  Watch as a team of wave
chasers heads to Somoa where they search for an undersea river
five kilometers beneath the ocean's surface. There they measured
skyscraper-sized internal gravity waves, which break and produce
strong turbulence underwater. Understanding these deep waves and
flows is critical to understanding more about the Earth's
climate and can help to improve climate models. The team is
still chasing waves: they now know where the waves start, but
they are still searching for where they end up.
