Skill Sheet 3.3: Tanya Atwater
1. Tanya Atwater came from a family of scientists—her father
was an engineer and her mother a botanist. Atwater recalls
many dinner discussions about science and she eventually
shared in her parents’ passion. Atwater and her family went
on many vacations. The family often found the most remote
places to explore. This explains Atwater’s deep love for the
outdoors.
2. In 1967, Atwater began graduate school at the Scripps
Oceanographic Institution in La Jolla, California. During this
time, many exciting geological discoveries were being made.
The concept of sea floor spreading was emerging, leading to
the current theory of plate tectonics.
3. While at Scripps, Atwater joined a research group that used
sophisticated equipment to study the sea floor off of northern
California. It was her first close look at sea floor spreading.
Atwater also took twelve trips down to the ocean floor in the
tiny submarine Alvin. She collected samples nearly 2 miles
down on the ocean floor using mechanical arms. Atwater’s
firsthand view through Alvin’s portholes gave her a better
understanding of the pictures and sonar records she had
previously studied.

10. The Mid-Atlantic Ridge has a slow spreading rate, while the
spreading rate of the East Pacific Rise is fast. Because the
Mid-Atlantic Ridge is so slow, a valley has developed
between the two separating plates.
4. Propagating rifts are created when sea floor spreading centers
realign themselves. This realignment is in response to
changes in plate motion or uneven magma supplies. In the
1980s, Atwater was part of a team that researched
propagating rifts near the Galapagos Islands off the coast of
Ecuador. She has also discovered many propagating rifts on
the sea floor off the northeast Pacific Ocean and evidence of
propagating rifts in ancient sea floor records worldwide.
5. Atwater has been a geology professor at the University of
California, Santa Barbara for over 25 years. Atwater also
works with the media, museums, and teachers to educate
them about the Earth. She has created presentations and an
animated teaching film, “Continental Drift and Plate
Tectonics,” that has been used by educators from the
elementary school level through college.
6. Answers may vary. Some of Alvin’s noteworthy trips include
locating a hydrogen bomb accidentally dropped in the
Mediterranean Sea (1966), several trips to the Mid-Atlantic
Ridge and Galapagos Rift, surveying the sunken ocean liner
Titanic (1986), and IMAX filming off of the San Diego coast
for a deep sea feature production (2002).
