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 that will be acquired on the FK161229 expedition. This will be his third expedition on the R/V Falkor and his first opportunity to visit the Johnston Atoll region. During this time at sea, he will be assisting his colleagues with multibeam data acquisition, processing, and interpretation.
