I'm very interested in marine science and conservation. Is there any information on how to build a buoy? Icing on top would be to constrain it in place as well, but if that's not possible, that can be worked around with GPS.

Probably the biggest hurdle is regulatory in nature (c:
Assuming that's been overcome, anchoring becomes the issue. As you can imagine that gets more expensive the deeper the water is. The nature and purpose of the buoy has an effect on this: if the buoy has to remain absolutely dead nuts stationary then a 3-point mooring may be required (and it still will move around a bit).
An interesting possibility is to have a wind powered buoy to keep it stationary. Basically you put a wind turbine on the buoy to drive a propeller in the water. The harder the wind hits it, the harder it wants to claw its way upwind. This is counter intuitive but it does work. But it assumes the main cause of drift is wind.
As for the buoy proper, you can buy them off the shelf in various sizes, or build your own.
