Amy Bower

Senior Scientist

Amy developed a strong connection to the oceans growing up in a small coastal town  in northeastern Massachusetts. Her high school math and physics teachers inspired her to pursue an undergraduate degree in physics at Tufts University near Boston. Through the off-campus Sea Semester program run by Sea Education Association,  Amy discovered a field where she could combine her curiosity about the oceans with her undergraduate training in physics—physical oceanography. During the summer between her junior and senior years at Tufts, Amy was an intern at the University of Rhode Island’s Graduate School of Oceanography, and subsequently earned her Ph.D. there. In 1988, under the mentorship of Professor Tom Rossby. she then accepted a postdoctoral scholar fellowship  at WHOI and has been there ever since, earning tenure in 1999 and the rank of Senior Scientist in 2005. Presently, she serves as Chair of the Department of Physical Oceanography. She is married and has one daughter.

Amy’s primary research interests  are aimed at understanding the structure and dynamics of the most energetic features of the deep circulation:  boundary currents (flows along the edges of the ocean basins) and deep mesoscale eddies (swirling masses of water typically 50 miles in diameter). These components of the deep ocean circulation have an important role in transporting heat, salt and other water properties (and the creatures that live in them)  long distances in the ocean. The pathways of these currents and eddies are hard to observe because they often have no expression at the sea surface. Amy and her team have used several techniques to uncover these mysteries of the deep, but most often they release freely drifting buoys that sink down below the surface, where they drift with the currents and are tracked underwater using sound. They have deployed hundreds of these so-called RAFOS (Ranging and Fixing of Sound) floats in the North Atlantic, Gulf of Mexico, and Indian Ocean. With these and other tools, Amy’s group has discovered the formation location of some deep eddies, tracked their life histories and eventual demise; uncovered previously unknown pathways of the deepest currents in the North Atlantic and Gulf of Mexico; and showed important linkages between the pathways of deep currents and the flows above, which in some cases are flowing in the opposite direction.

Legally blind for over 20 years, Amy has learned to use several adaptive technologies to continue her research. These include video magnifiers for enlarging text and graphics, scanners for converting print into speech, and screen readers and magnifying software on the computer. There have been four canine members of Amy’s group:  Winslow, Abby, Echo, and most recently, Intrepid, a black lab guide dog from  The Seeing Eye in New Jersey. Intrepid doesn’t yet have his sea legs, but he travels everywhere else with Amy, including meetings and conferences.

Heather Furey

Research Specialist

Heather has been working in the Bower Lab since 1997, doing everything from managing field programs, to helping ballast floats, to putting together presentations for conferences, to writing scientific publications and proposals. Heather joined WHOI in 1997, after completing an M.S. in Physical Oceanography from the University of Alaska, Fairbanks, and a B.A. in Physics and Studio Art from Smith College.

Andrée Ramsey

Research Associate

Andrée joined WHOI in 2010 and has been involved in processing, quality control, and analysis of both Eulerian and Lagrangian flow data in an effort to better understand ocean dynamics.  Currently, her focus is on mesoscale circulation in the subpolar North Atlantic and its relationship to the Atlantic Meridional Overturning Circulation.  She received her B.A. from the University of Colorado, her M.S. from Boston College, and worked for several years at USGS in Woods Hole before joining WHOI.

Anna Pinckney

Research/Access Assistant

Anna joined WHOI in April 2024 and is the newest addition to the Bower Lab. She received her B.S. in Environmental Science from Stonehill College, her M.S. in Atmospheric and Oceanic Science from the University of Colorado-Boulder and worked for 2 years as a science teacher before joining WHOI. Anna supports multiple Bower Lab projects and works on improving accessibility of science to those who are blind and visually impaired.

Jim Valdes

Emeritus Research Scholar

Jim has been a critical part of the Bower Lab for over 25 years. Before that, he was instrumental in the development of the predecessor  to the RAFOS float, the SOFAR (Sound Fixing and Ranging) float and its use at WHOI by Emeritus Scientists Breck Owens, Phil Richardson and Jim Price. His extensive knowledge in electronics and mechanical systems as been the foundation of the RAFOS float lab at WHOI, from building and tuning the sound sources used for float navigation, to float ballasting, design modifications and improvements.


Guide dog Intrepid sits on a cushioned chair and poses for a portrait.



Intrepid is a true “lab” member. A labrador-golden retriever mix, he joined WHOI in 2017 and is a proud graduate of the Seeing Eye guide dog school in Morristown, NJ. Intrepid spends his days deep in thought on his favorite chair in Amy’s office and accompanying her wherever her busy days take her.
