AND IF YOU HAD TO CHANGE YOUR PROFILE TO A GIRAFFE… MAKE SURE THE OUTFIT WAS IRONED
Oceanography: Exploring Earth’s Final Wilderness – Prof. Harold J. Tobin
I thought this would be a fun course with mostly Attenborough-esque sceneries and lots of cool info. It was way more than that. I got to learn so much and as always I’ve just taken notes of whatever stood out to me.
- Land info called maps, ocean maps called charts. Navigating with sextant and Captain cook and Darwin history.
- Bartymetry – measuring the depths of the ocean.
- 1 episode just for the Big Bang solar system formation volcanos. 90 billion year history.
- Process and history of making natural oil and gas that we use, how people drilled for it. The consequences of spills and ways to recover from it.
- Different shades of pink salt because different algeas thrive in different salinity.
- Amazing properties of water. Way more then boiling and freezing points. Changes in temperature, density, salinity and pressure in the different levels as you go deeper. Light and colour blue as you go deeper because the other colours/frequencies are not strong enough to go deeper.
- Tides are 1 third sun and 2 third moon gravitational pull.
- Springtide during full moon & new moon because sun and moon are aligned and pulling tides together.
- Tidal bores happen in narrow places where the wave builds up on itself like River Severn.
- Moon and sun are slowing down earths rotation by 2.3 milliseconds per century.
- Gasses get more soluble the colder water gets.
- Different plankton adapt their bodies in different levels to live.
- The word twilight zone originally came from oceanography.
- Jellyfish pulsing is more to sweep water to get the food from it, propulsion is just a byproduct.
- 25% of fish caught for food are thrown away because the ship is not equipped to process these types and are already dead!
- Importance of mangroves because of their roots. The trees look amazing! Kelp and mangrove forests are beautiful.
- Beach replenishment to preserve beaches from erosion. Millions are spent to put back sand on the land.
- Corals are really animals! And a 1-1.5 degree change in the water can kill them (coral bleaching).
- Sea pigs are basically water balloons and they pump water into the leg they want to move.
- El Niño comes from current of baby Christ.
- Kiribati, Tuvalu and Maldives are going to sink in a matter of decades. And the president of one of them is already vacating the inhabitants.
- There is a saying regarding sewage that goes … solution to pollution is dilution. Well its not any more!
