Summary: Paleomagnetic measurements on International Ocean Discovery Program Expedition 352 basalt samples were undertaken to augment work done on board the R/V JOIDES Resolution during the expedition. A total of 177 new samples were measured using thermal demagnetization experiments with the goal of determining paleomagnetic inclinations from samples for tectonic studies. It was possible to estimate a characteristic remanent magnetization direction from 96% of the measured samples. New data were similar to those of the Expedition reports, with a large range of natural remanent magnetization values and variable demagnetization behaviors, both implying magnetic carriers with a variety of compositions. Paleoinclination values generally matched those found previously, with many having low values indicative of formation near the Equator
