1. First study to show that seismic imaging detects ocean's internal tides

Internal tides, waves below the ocean's surface that propagate at tidal frequencies, play an important role in ocean mixing but can be difficult to detect and study. Holbrook et al. find they can detect these waves with seismic imaging. Using seismic data acquired in the Norwegian Sea, the authors observe bands of reflections that indicate internal tides. The study is the first to show that seismic imaging ca
