With love for geoscience comes a zest for exploring the natural world. What we want to explore might not always be close to us. But science finds a way, even if it means sailing to the middle of the ocean. This week, we are going to dive into the nuts and bolts of how research cruises work in this blog post by Kuan-Yu Lin from the University of Delaware. Kuan-Yu recently sailed as an igneous petro ...[Read More]
