Karen Harpp: Research in the Galápagos

Plume-ridge interaction in Northern Galápagos

map of the Galapagos spreading center The goal of this project is to understand the way mantle plumes interact with mid-ocean ridges. In the spring of 2010, we carried out an oceanographic cruise to the Galápagos, during which we mapped the region between the Galápagos Spreading Center (a mid-ocean ridge) and the main island chain to the south. This was a five-week cruise staffed by a team of undergraduate students and senior scientists. We sampled nearly 50 submarine volcanoes by dredging the ocean floor. We also collected geophysical data (gravity and magnetics), and mapped an area larger than the combined area of Massachusetts and part of Connecticut using multibeam and sidescan sonar methods.mapping compared to NE US

This and previous Galápagos work has been funded by grants from the National Science Foundation, and have been collaborative with several institutions, including Woods Hole Oceanographic Institution, the University of Idaho, and Ithaca College, among others.

The map to the right shows the area we documented during the cruise and how it compares to the eastern US:
