Heezen dismissed this as “girl talk” - though really a vital piece of #PlateTectonics puzzle.
Tharp believed rift was real though she hadn’t convinced Heezen. In 1952, they began working on physiographic maps, which really gave a sense of the geology, & were not US Navy classified, so they could publish. A 2nd project involved plotting earthquakes, & Heezen insisted they work at same scale. Heezen noticed that ocean earthquake epicentre data also formed long lines - 
Hired as technician "she had a hard time convincing [her superior, PhD student] Heezen, who initially dismissed her ideas as "old wives’ tale". In fact, it took #Tharp a whole year to persuade her male colleague that she was right, by showing the correlation between her #bathymetricMaps and that of earthquakes in the Atlantic"
"Being a #woman, she wasn't at that time allowed to embark on oceanographic vessels, or earn a PhD"
#GreenlandIce usage

... a thought experiment, let's reduce the geographical reach for a moment, b/c "thinking globally" never solves any real-world problems:
The American north east, the area b/W #CAN and #DK (#Greenland.)
I have no idea about water depths and #PlateTectonics in that region, but wouldn't a #WaterPipeline be feasible?
#CAN will need increasing amounts of water for #ForestFire fighting, and more and more...

In less than 10 million years, California could be an island offhore of North America, and the new coastline might be in Nevada. Geologists are studying an extensive series of earthquake faults in western Nevada to determine whether parts of western North America might be starting to wander off.

“HIGHLIGHTS:
• Earth may have had a ring during the middle Ordovician, from ca. 466 Ma.
• Breakup of an asteroid passing within Earth's Roche limit likely formed the ring.
• Among several features preserved is a near-equatorial band of impact craters.
• Shading of Earth by the ring may have triggered a global icehouse period…”

Why study and synthesize #Ringwoodite? Experiments (below, a diamond anvil pressure device that's transparent to visible light; Schmandt et al, 2014) and natural samples from the Earth's mantle (see ksircombe's posts: https://aus.social/@ksircombe/113124213223248687) suggest that there's an ocean or two worth of water stored in Earth's Ringwoodite. It's likely kept the planet habitable for the last 4.5 billion years.
Plus Ringwoodite is more Blue than #Kyanite !
