|Float and ship paths over time. The red triangle that looks like the ship ran it over is probably the float we saw with the spotlight at 3am.|

The path the floats are following results from a combination of the mean current of the ocean as they profile, which seems to be generally toward the southeast at the moment, and what are termed “inertial motions”, which is an oscillatory motion that occurs due to the rotation of the earth. We see this show up as periods of speeding up and slowing down in the float positions.
