Langseth, we’ve zigged and zagged our way over a 360×240 mile region of the Pacific plate, first dropping instruments to the seafloor, and then shooting airguns to them (see previous posts). The final step is to recover a subset of the instruments: 34 ocean-bottom seismometers…

The Shock of the New
During the eighteenth and nineteenth centuries, a host of naturalist-explorers traveled around the globe in a quest to identify new species. We interview science writer Richard Conniff, who evokes this grand age of discovery in The Species Seekers: Heroes, Fools, and the Mad Pursuit of Life on Earth, just released in paperback.
