Extreme weather events and sea level rise are increasing, intensified by a warming ocean. Understanding heat in the ocean can help better predict extreme weather and long-term climate shifts. A network of robotic instruments called Argo is helping scientists track warming beneath the surface and it’s showing us the ocean's heat content is increasing steeply. This video shares just how much the ocean is warming, and how the Argo program needs more support to continue to give society the full picture of ocean warming. #Argo #OceanWarming #OceanHeat #MarineHeatWaves #ScrippsOceanography #UCSanDiego #COP28 Animation by Jessica Kendall-Bar. https://jessiekb.com Science Advisors: Sarah Purkey & Megan Scanderbeg - Climate, Atmospheric Sciences, and Physical Oceanography, Scripps Institution of Oceanography, UC San Diego.

For the first time, scientists have recorded brain activity in a free-ranging, wild marine mammal, revealing the sleep habits of elephant seals during the months they spend at sea. The new findings, published April 20 in the journal Science, show that while elephant seals may spend 10 hours a day sleeping on the beach during the breeding season, they average just 2 hours of sleep per day when they are at sea on months-long foraging trips. They sleep for about 10 minutes at a time during deep, 30-minute dives, often spiraling downward while fast asleep, and sometimes lying motionless on the seafloor. The research was led by Scripps Institution of Oceanography postdoctoral fellow Jessica Kendall-Bar when she was a graduate student at UC Santa Cruz. Study co-authors include a team of researchers affiliated with UC Santa Cruz and several other research organizations.
