Woods Hole Oceanographic Institution, or WHOI, is an American private, non-profit marine science research facility that undertakes studies of the physical, chemical, and biological features of the ocean environment.
It was established in 1930 on Cape Cod, in the village of Woods Hole near Falmouth, Massachusetts, from where it operates laboratories, oceangoing research vessels, and runs marine science post-doctoral research and graduate degree programs, the latter with the Massachusetts Institute of Technology (MIT).
WHOI is funded by grants from federal government agencies such as the National Science Foundation and the Office of Naval Research, private contributions, and endowment income.
