jtotheizzoe: Happy World Oceans Day! They cover most of our planet. They are home to the vast majority of life on Earth, much of which we haven’t even discovered. They are mostly unexplored, mysterious dark depths teeming with curiosities. They are the sites where new parts of our planet are born. They are our oceans. And many of them are in trouble. Find out how you can help here. If you’d like to spend your day filling your brain with ocean facts (you know you do), there’s a simply amazing tidal wave of knowledge over on Twitter at the #oceanfacts tag today. Go learn ya somethin’. Bonus: To celebrate World Oceans Day in a particularly beautiful way, revisit this Van Gogh-esque NASA visualization of the ocean’s currents: Perpetual Ocean.
