The Ocean Is Deeper Than You Think. We Need Better Maps.

Pleeeeeease give me more excuses to go look at beautiful maps!! This was so fun thanks for looping me in ✨

I'm an avid scuba diver but no matter how many times I dive I realize I am truly in a different world. There are common things you see as a scuba diver on a reef that most people never get to experience. For example a fish cleaning station with a line of fish waiting their turn to be cleaned by tiny gobies and other types of fish and shrimp. I'm so glad you're doing the series there's so much still to be learned! Thanks Cleo!

Who found this channel randomly or through shorts and now cant stop watching....I CANTT THESE VIDS ARE SO GOOD, the production quality is top notch

I remember learning as a little kid (I’m still young) that we had only mapped 5 percent of the ocean floor. This is so fascinating to me!

The best part about the Thorpe maps was that they were the first concrete evidence for plate tectonics and she is often credited in geology with providing the last piece of the puzzle that pushed the theory of plate tectonics from fringe idea to mainstream scientific theory.

That Marie Tharp map of the ocean floor was straight up incredible. The amount of dedication and skill to finish them is fantastic. I can see how Johnny loved going to the library to look at 'em 😅

Amazing to see how Marie Tharp could make those high quality maps with the limited data she had. I find it really interesting to see how a combination of old and new tech helps us to make an even more accurate map of this mysterious underwater world!

I started working at a large private seabed/subsea bed mapping company that did surveys around the world for oil companies at 17 back in 2007 through a friend of my grandma. They wanted a tech legit ‘go for’ and liked my honesty and ability. Anyway, I was immediately trained on how to map seabeds, not hard, and start learning sub seabed imaging, also not hard. The problem with mapping large areas of the seabed is it takes a while for the boats to move out, and the expense.  At the company we worked with both a 2d and 3d approach. The singular lines and guessing where and how the undersea ranges are, as shown in the old depth map with Johnny, are the 2d surveys we did. 3d surveys to mor accurately show the sea floor, and what is below, cost more and take way more time for the ships to complete. Disclaimer: I stopped working at that company in December 2015, so my knowledge on the cost of surveys and new tech may be out of date.

Retired ocean lifeguard here, I love the part about the surface giving away the bottom contour. It’s exactly what’s happening in the shoreline. Slightly deeper water breeds rip currents. The water’s shape and color tell a story all day long about the shape of the bathymetry under! A crew that rowed across the pacific from LA to Hilo followed deep trenches leading away from California helped by those currents. It’s amazing.

As a kid, I've heard that when you say "detailed map" five times into a mirror, Johnny Harris appears behind you.

I live Hilo Hawaii. What you’ve said is true. My house is oceanfront I see the ocean move at all times. The ocean ridge that extends off the island creates a very strange and interesting ocean condition that’s fascinating. We live off of the oceans resources. So knowing how it works is very important to us. Youve done a great job. I love the show.

it's always scared me how little we know about our oceans..

Great video! Just for a stat, I created the first generally accessible and affordable high-resolution mapping program using the World Database II way back in 1978. It was called AMP - A Mapping Program. And, while the National Center for Atmospheric Research (NCAR) had a program that used the World Database II to create maps, it was very expensive to use. I compressed the entire WDBII onto one Cyber 750 "Disk Pack" at 5 levels of resolution. Using just 5 lines of Fortran code, any student, researcher, scientist could create a map of any part of the world at up to 1 point every 300m resolution WITH their data presented in a variety of methods and usually at a cost of less than $5 (NCAR program to produce the same thing typically cost in the $50s to $100s of dollars in compute time). The program was used at the University of Washington for maybe 5 to 7 years by many departments and hundreds of users. Little did I know that I was at the very beginning of what eventually evolved into Google Maps!

I am absolutely terrified of the oceans or really any large body of water, even being in a city near one makes me feel uneasy.... The idea of being in the water and having miles of it underneath me is especially terrifying.

My dad is an oceanographer, and he uses gliders to capture data about the ocean floor, current, temperature etc. Very interesting video!

“If you want to see aliens, go to the oceans” Time 3:12 Simply brilliant!

When I was a young man, my father (an avid fisherman who died in 1987) always had the latest technology available at the time. A "depth finder" and a "fish finder" and a Loran for navigation. It was primitive by today's standards, and I wish he were around to see how the technology has advanced.

Love that Cleo's videos seem to be trending longer. I would absolutely watch a 30-60 min Cleo Abram video from end to end. Or listen to a 1-3 hour podcast, for that matter! 🤠

We (the US) actually have extremely good maps of the oceans, we just don't openly publish them for reasons that include national security. The best maps that we do have were not built by public agencies. In the private sector, companies like Exxon have amazing maps of the sea floor in areas that interest them. They do not share these with others.

"We can't be afraid of knowledge for fear of what we'll do with it." Wow! What a statement. I've always loved this. Once, I worked for a group of computer system administrators, some of whom knew much less about the operating system (AT&T UNIX) than we specialists did. For many of them, their attitude was "Don't type that command! You never know what might happen." I couldn't help but laugh because the one who actually said that had no idea of asset permissions. He didn't which level of permissions was dangerous and which was harmless, a perfect example of fear from lack of knowledge. I told my him, "We're safer when we understand why certain things are dangerous." I've always believed that it's smart to learn as much as we can before attempting the unknown so we'll be prepared. If we fail to prepare, we prepare to fail.
