Loop Current dynamics array and CICESE’s arrays. Deployment: April 2009. Rotation: July and November 2010. Retrieval: November 2011....................................................................................................................... 25 Figure 1A.2. 13-month mean fields for selected isotherm depths (corrected for mooring draw down caused by strong currents), 40-hour low pass filtered currents, and SSH from the altimeter gridded products. .......................... 27 Figure 1A.3. Crest-trough upper-lower layer coupling, July–August 2009............................... 28 Figure 1A.4. Ensemble averaged time-series of transports across the boundaries of the deep eastern Gulf control volume (see text) across 90˚W (black), Yucatan Channel (blue), and z = -1,000m horizontal plane (red). Also plotted are the Florida transport (gold curve) and the difference between the area-mean SSH in the eastern Gulf and the Caribbean Sea (dashed). The time-axis is over the Loop Current Cycle of 240 days with Stages A, B and C as discussed in text (see also Chang and Oey 2011). To show more clearly the relationship between the different variables during a Loop Current Cycle, a 30-day running-average has been applied to all the time series. ...................................... 33 Figure 1A.5. Monthly-binned histogram of the Loop Current eddy separation times for the 45 separation events observed in the 30-year record, 1980 through 2009. ............................................................................................... 40 Figure 1A.6. Scatterplot of retreat latitude versus separation period of the following Loop Current eddy separation event. Regression lines for various subsets of the data record are shown along with the prediction regression model (black line) for the entire record. .............................................. 40 Figure 1A.7. RAFOS float trajectories from the Exploratory Program (April 2003 to May 2004). The floats were deployed at various depths from 1,000 m to 3,000 m at 500 m intervals. The sound source locations are marked by the red diamonds, and the steep S Sigsbee escarpment at the base of the northern continental slope is shown by the gray shading. Note the concentration of floats and their westward transport along the escarpment. ........................................................................................................... 46 ix Figure 1A.8. Sound source locations (red diamonds) and preliminary deployment cruise tracks for the three-year field study. The gray shading represents the sound source coverage for depths greater than 1,500 m. Shadow zones are the small areas where only one source can be used and therefore location fixes are not available. ............................................................. 46 Figure 1A.9. Five Barnys equipped with ADCPs (red dots) are moored at the East Flower Garden Bank. Four temperature/conductivity string moorings (blue stars) are located next to Barny moorings 1–4.
