Early Life and Formative Influences

The Lamont Years and a Unique Collaboration

At Lamont, Tharp was paired wigh Bruce Heezen, a charismatic and ambitious geologist who was athering sonar profiles frem research ch vessels crossing thee Atlantic. The arrangement was, by the standards of the time, unusual: Heezen collected thee data sea, while Tharp - barred from shipboard work because women were considered bod luck on research ch vessels - turned raw echo soundings into map sheets onshore.

Connecting thee Maps to Continental Drift andd Seafloor Spreading

Tharp and Heezen 's map of thee North Atlantic, published in 1957, revealed thee ocean bottom as a dynamic realm of mountains, trenches, and fracture zons. The timing was critical.
