Shark may avoid cold blood by holding its breath on deep dives
Scalloped hammerhead sharks stay warm as they descend into cold, deep water off the coast of Hawaii, suggesting the cold-blooded species may maintain its body temperature on dives by holding its breath, according to new research presented at the Ocean Sciences Meeting 2020 in San Diego, California.

The Blob hides in the deep
Fall is nearly here and, for most of us, that means the end of the summer heatwave. In the waters of British Columbia, however, the seasonal cycle is stuck. A marine heatwave began more than four years ago and new research suggests it won’t be disappearing anytime soon. Marine heatwaves are not new. But heatwaves are getting more intense and more frequent with a changing climate. Over the fall and winter of 2013 and 2014, satellites detected above normal temperatures in the surface waters of the northeast Pacific. At its peak, the mass of warm water—nicknamed “The Blob”—had water temperatures up to 3 °C warmer than normal and covered an area larger than Australia.

What brings people to the 2010 Ocean Sciences?
“I am chairing a session on satellite altimetry research on Friday. It promises to be very exciting, because hopefully people are going to argue with each other about what the oceans are doing.” Josh Willis, NASA’s Jet Propulsion Lab “I’m a sophomore in marine biology. This is my first time at Ocean Sciences. I will not be presenting; I’m watching and observing. I’m currently doing undergrad research with phytoplankton and …
