1. fetch, wind speed, wind duration
2. a rate of the amount of water movement
3. idrk but im guessing its an element that can be used to trace water masses.
1) Correct.
2) More specifically equivalent to 1*10^6 m^3/s.
3) Tritium is a radioactive isotope of hydrogen with 2 neutrons. I'm pretty sure it would be used for tracing like you've said.
Umaroth's corrections are right, so I believe they get to ask questions next

Since Umaroth didn't make questions:

1)What does a CTD measure?
2)What did the MMPA (Marine Mammal Protection Act) do?
3)What percent of the oceans are deemed unexplored (sorry for the randomness)?
I enjoy Dynamic Planet.

1. A CTD measures conductivity, temperature and depth.
2. I don't really know, is it an act that protects marine mammals off the coast of the US? 3. I don't really like this question because it is very vague. What does "unxplored mean? The total volume of the ocean is about 1.4 billion cubic km(thanks Fermi) and I can't imagine humans have been to more than a ten-thousandth of that? So maybe 99.99%?

For 1: A CTD actually measures conductivity, temperature, and pressure. They use pressure to determine depth.
2: the MMPA protected marine mammals from potentially harmful human activities. (you mostly got that one).
3: When you google it is comes up as 95%, so that's what I went with.
Your turn!
I enjoy Dynamic Planet.
