Joe Ortiz from Kent State University joins us to talk about using micro-fossils to learn about how climate changes over time, the Beaver-SCAT instrumentation, spending two months at sea in the North Atlantic, remote sensing and collecting sediment cores at sea, research at the Bering Strait, spending 3 days stuck in the ice, strategies for avoiding polar bears, identifying algae from space, harmful algal blooms, machine learning techniques, the benefits of open-source software for remote sensing and analysis, and multispectral UAS imagery analysis.
