What are some ways to track water movement?
Two of the main ways to track water movement are floats that are weighed down to a neutrally buoyant depth and surface drifters that follow the surface current and send signals to satellites or nearby radar signals.

At what latitude is the Coriolis effect the weakest? Strongest? Will it make me throw up?

Coriolis effect increases with latitude, so equator = weakest and poles = strongest; I highly doubt it

How do you calculate the density when given temperature and salinity in ppt?

Use a T-S diagram?

I honestly don't know the answer and was hoping you knew a formula.
That's valid though, go ahead

The form of the equation of state is:
o AS + BS^3/2 CS^2

Where A, B, and C are functions of temperature (ºC) and S is salinity. The coefficients
for the combined data are:
A = 8.24493 x 10-1 – 4.0899 x 10-3 t + 7.6438 x 10-5 t2
– 8.2467 x 10-7 t3 + 5.3875 x 10-9 t4
B = -5.72466 x 10-3 + 1.0227 x 10-4 t – 1.6546 x 10-6 t2
C = 4.8314 x 10-4

Here's probably what you're looking for but I doubt you'll ever need to use this formula. Most density calculations on tests I've taken comes in the form of a T-S diagram.

As for my question...
What are the differences between El Niño and La Niña. Make sure to also compare with "normal" conditions.
