Jonathan Tree is a marine geoscience data technician at the University of Hawai‘i at Mānoa where he also graduated with a Master’s degree in Geology and Geophysics. Continuing work in the same region as his master’s research, the Northwestern Hawaiian Islands, he is currently developing the first detailed geological interpretation map of the submarine flanks of the oldest Hawaiian volcanoes. His work relies heavily on high-resolution multibeam bathymetry and backscatter datasets like the data on this research cruise, as well as the data acquired on the FK161229 expedition, which was his first opportunity to visit the Johnston Atoll region.
This will be his fourth expedition on the R/V Falkor and his third visit to the Hawaiian-Emperor volcanic chain. During this time at sea, he will be assisting his colleagues with multibeam data acquisition, processing, and interpretation. In addition to imaging the seafloor, Jonathan will also be working with the marine geophysical dataset that we are collecting along the multibeam data using a gravimeter and a magnetometer. The gravimeter measures small changes in the gravitational changes, while a magnetometer measures small changes in the magnetic field – these instruments help reveal non-visual information about the interior of the volcanoes we’re surveying.
