Dynamic Planet (Oceanography)

[JoeyC]

Yup!
For number 3:
Wind forcing creates a downwelling Kelvin wave heading towards the East and an upwelling Rossby wave heading towards the West. When the Kelvin wave reaches the coast of Latin America (faster than the Rossby wave cause it's faster) El Nino starts, The Rossby wave is eventually reflected by the Western ladnmasses and returns as a Kelvin wave. The period in between these two events is the El Nino time. This theory is known as the Delayed Oscillator theory.

Questions:
1) What type of current makes submarine canyons and where do submarine canyons occur?
2) Why do waves break when they reach shore?
3) What types of waves are ocean waves?(As in what types of waves are ocean waves classified as?)

Uh, usually the person who answered the previous question, asks the next. So in this case that’s silver breeze

I'll just answer these, then post my own questions?

1. turbidity current, continental margins
2. The water molecules at the bottom of the wave start to strike the seafloor, causing the wave to grow in height. The trough is slowed by friction, and the crest rushes ahead and topples.
3. surface waves?



1. What letter do the isohalines of a slightly-stratified estuary resemble?
2. What does a piston corer do?
3. What is Forchhammer's principle?

1. No clue, gonna guess S
2. Collects sediment samples via pressure differential and, as all corers do, jamming a tube thingy into the ground
3. Regardless of location, ratios of major constituents of seawater remain the same

[SilverBreeze]

All correct. Your turn!

[BennyTheJett]

Welp, time for a revive.

1: Name 2 of WHOI's RVs, ROVs, or Submersibles

2: How do sponges (poriferans) obtain nutrients essential for their survival.

3: If you observe a semidiurnal high tide at 4:00 PM, what time would you expect the next low tide?

[adarsh]

1. HOV Alvin and ROV Jason/Medea (I had to research this)
2. They obtain them by filtering plankton/other nutrients through the water using specialized cells
3. 4:25 A.M.?

[BennyTheJett]

3 would be 10:25 pm. I was looking for the low tide after giving the high tide. Other than that, spot on.

[adarsh]

1. What is the general term applied to sediments deposited by turbidity flows, and what bedding does it show?
2. What is the difference between a mid ocean ridge and a mid ocean rise?
3. What is longshore drift and why does it occur?
