Research Positions

Currently seeking multiple graduate students to fill positions at the MS and/or doctoral level. Research topics include: living shorelines, beach and tidal inlet dynamics, barrier island response to extreme events, groundwater impacts to coastal lagoons, and infrastructure resilience. Research assistantships are available. Contact me for more details.

One of our drifters (DISL023) released at the 20-meter isobath on April 26, 2012 woke up after an extended nap and started reporting again on October 16, 2012. In the days that followed, the drifter made it into the Loop Current, scooting quickly across the southern portion of the Gulf of Mexico headed toward Fort Jefferson in the Dry Tortugas at speeds approaching 2 knots. The drifter has now merged with the Florida Current. Click on the image at right for the interactive tracking page. Also, you’ll see a small embedded tracker as the second item in the left hand column of this page.

 

The figure below shows a comparison of the drifter trajectory and mean ocean surface currents for the period 10/15 – 10/25. The data were obtained from the NOAA OSCAR system, which provides satellite derived estimates of ocean surface currents*. The inset panel shows more detail around the drifter trajectory, along with drifter speeds (m/s) and position dates (10/16, 10/26). Note the excellent agreement between drifter speed and ocean current magnitude (using the color scale at right). Clicking on the image below will take you to an enlarged version for easier viewing.
