Bruce Peter Luyendyk (born 1943) is an American geophysicist and oceanographer, currently professor emeritus of marine geophysics at the University of California, Santa Barbara.

Luyendyk attended San Diego State University (SDSU) where he obtained a bachelor's degree in geology and geophysics.

That expedition, to the western and south Pacific, and led by Robert Fisher and William Riedel, inspired Luyendyk to follow an education and career in oceanography.

His projects include documenting the ninety degree or greater clockwise rotation of the Transverse Ranges during the Neogene Period of the Cenozoic Era.

[6][7] Principal discoveries included that of a basin-wide unconformity of Oligocene age in the Indian Ocean that was likely related to initiation of ice sheets in Antarctica[8] and uplift of the Reykjanes Ridge due to the Iceland hot spot.

[1] This research earned the team the Newcomb Cleveland Prize from the American Association for the Advancement of Science (see 1980, Spiess, Macdonald and 20 coauthors).

[10] During the 1990s, Luyendyk and colleagues began a study of the marine hydrocarbon seep field at Coal Oil Point, California.

[12] In the late 1980s, Luyendyk and David Kimbrough of SDSU launched two expeditions to the Ford Ranges of Marie Byrd Land in West Antarctica.

Antarctic geologist Christine Smith Siddoway accompanied them to conduct her graduate dissertation work on metamorphism and deformation within the Fosdick Mountains.

[14] Follow-on research by others discerned the recent retreat of the West Antarctic Ice Sheet in the region,[15][16] first noted here by the FORCE expeditions.

[21] In the later part of the 1990s, Luyendyk teamed with Andrea Donnellan of the Jet Propulsion Laboratory to use GPS to measure the rate of opening across the Ross Embayment between West and East Antarctica.

[24] Achieved through joint work with Douglas S. Wilson, revelations about the topography of the subglacial and nearshore marine environments of the eastern Ross Sea led to an interpretation of paleotopography at a time of climate transition that preceded continental glaciation of Antarctica.
