Chiou, M.-D., S. Jan*, J. Wang, R.-C. Lien, and H. Chien (2011) Sources of baroclinic tidal energy in the Gaoping Submarine Canyon off southwestern Taiwan. Journal of Geophysical ResearchOceans, 116, C12016, doi:10.1029/2011JC007366.


Colored arrows indicate the energy flux of the internal tide flowing in and around the Gaoping Canyon, with warm colors denoting high flux and cool colors low flux. The internal waves are heavily influenced by steep drops in the sea floor at the Taiwan and Luzon straits. (Graph: Tien-Hsa Kuo)
