We compiled a bunch of temperature proxy data and concluded that the Miocene Climatic "Optimum" wasn't significantly warmer than the rest of the (very warm) early Miocene. The MMCT was definitely a cooling. Implications for CO2 versus ocean circulation mechanisms. www.science.org/doi/10.1126/...

Ocean circulation changes rather than global warming drove temperature trends across the Miocene Climatic Optimum
Early-to-Middle Miocene [23 to 13.8 million years ago (Ma)] climates were ∼6° to 9°C warmer than today. Around 16.9 Ma, benthic foraminiferal oxygen isotope (δ18O) records suggest pronounced warming, ...

Legendary oceanographer Dr. Sylvia Earle led the first all-female aquanaut team & has logged 7,000+ hours underwater. As NOAA’s first female Chief Scientist, she expanded marine research & holds the record for the deepest untethered ocean floor walk at 1,250 ft (381m). #WomenInSTEM (1/2) 🧵
A vibrant photograph of American marine biologist and oceanographer Dr. Sylvia Earle (born August 30, 1935) sitting beside a modern single-passenger research submersible on a sunlit pier. Dr. Earle, celebrated for logging over 7,000 hours underwater and serving as NOAA's first female Chief Scientist, looks directly at the camera with a bright, welcoming smile. She wears a vibrant red fleece jacket featuring two circular expedition patches on the chest—one displaying a blue "Sustainable Seas Expeditions" logo—layered over a pale yellow turtleneck collar, paired with blue jeans and a gold watch on her left wrist. Her brown hair is styled in a short, casual cut. Her right hand rests near a large, cylindrical underwater camera housing equipped with thick lime-green mounting bands. Behind her sits the black-framed submersible, showcasing its prominent, clear acrylic spherical cockpit dome. A dark blue banner with white text reading "-NEW" is affixed to the side of the vessel. The bright outdoor background reveals harbor structures and a building. The overall mood is triumphant and inspiring, capturing a historic pioneer of marine technology.
