The MPC Drifters are back in the water this week as our MBARI collaboration continues for a second week. The data on the image above represents about 27 hours of data, from the afternoon of October 5 to about 6 pm local time of October 6. It illustrates quite nicely the 24-hour periodicity that is evident in much of our data. We have semi-diurnal tides here on the coast of California, so that pattern is not tidal. The drifters tend to have a stronger SE component of motion in the afternoons and a stronger NW component of motion in the early morning hours.
I’m trying to get some images of students deploying and retrieving the drifters. I’ll post them as soon as I get them.
