Bio/Research
My group was the first (and only) to deploy pop-up satellite tags and video packages (National Geographic Crittercam) on large Humboldt squid to record their second-to-second movements and color-changing behaviors. This work showed that this active predator spends a great deal of its time at depths of 300 m or more where the oxygen concentration is extremely low – less than 10% of that at the surface. This ‘oxygen minim zone’ (OMZ) is found throughout the southern half of the Gulf of California and much of the eastern Pacific Ocean, including Monterey Bay. The OMZ has been moving closer to the sea surface over the last few decades, and this aspect of marine climate change is expected to have major ecological consequences as ocean’s oxygenated surface zone becomes increasingly vertically compressed.
