Description of Project (Attach additional pages as necessary) 2.1 Nature and objectives of the project: This research program seeks to understand: 1. Means and direction by which information gets routed through the archipelago. We know that the interior is forced to some extent by fluctuating pressure distributions around the edge. On the Pacific side these come from westward propagating Rossby waves that hit the Philippine coastline and from
2. 3. 4. Kelvin or other coastal waves propagating along the coast. There is undoubtedly forcing from the South China Sea as well. To what extent do these signals propagate into the archipelago interior? Is the flow of information primarily westward? Are the signals important in establishing the interior flow, or is the latter primarily driven by wind and other local forcing? Processes governing flow partition in multiply-connected domains, including investigations of flow separations, internal waves, instabilities and sidewall eddy generation. The dominant dynamical balances that characterize the flow at different locations and scales. Response to (relatively) small-scale wind shear created by orographic effects on monsoon winds. Directed by remotely sensed sea surface temperature, wind speed and ocean color images, we will characterize the temporal evolution and three-dimensional structure of selected features by occupying repeated survey patterns with two towed profiling platforms. The proposed measurement program exploits two towed profiling vehicles (Triaxus and) to address the challenges posed by the rapidly-evolving, three-dimensional nature of submesoscale features within Lombok Strait. The vehicles offer complementary sampling capabilities that allow rapid, broad-reaching surveys, measurements near the surface and bottom boundaries, provide lateral resolutions of O(100 1000 m) and support a dense array of physical and optical sensors. Triaxus offers rapid tow speeds that allow broad, synoptic coverage. The Triaxus E model (Fig. 6a) is a new-generation towed profiler that has recently passed its sea trials. Triaxus profiles from the surface to 350 m (or deeper, depending on sea state) at tow speeds of 2 10 knots and can profile offset to the side, outside of the towing vessel s wake (providing improved surface layer characterization). Large foils control pitch and yaw, while smaller trim tabs stabilize the vehicle against roll. Vertical speed remains nearly constant (typically chosen as 1 m/s) throughout the profile. We also operate a hybrid SeaSoar (TriSoarus, Fig. 6b) that has been modified to improve flight performance when operating on unfaired tow cables. Dual single-mode fibers provide high-bandwidth telemetry to support a broad range of sensors. Both vehicles accommodate extensive payloads including dual Seabird CT, 1200 khz ADCPs, SBE43 dissolved oxygen, Wetlabs transmissometer, chlorophyll and CDOM flurometers, additional optical sensors to be added by Jones, Boss and Marra (see below), attitude package, dual Tritech altimeters and an acoustic transponder. (a) Figure 6. (a) Triaxus and (b) TriSoarus towed profilers. Triaxus can exert lateral control and operates over a wide range of tow speeds. TriSoarus is a hybrid SeaSoar with electric wing actuation and over-sized flight surfaces. Both carry SBE911+ CTD systems and an advanced fiber-optic MUX that eases sensor integration. An electro-optical tow cable provides high-bandwidth telemetry. The two vehicles share winch, tow cable, electronics, terminations, control and data acquisition systems. Vehicles can be
exchanged rapidly, with minimal reconfiguration, as part of routine operations.

Pierre Flament, Cesar Villinoy and Laura David, and the regional survey and towed profiler cruises that took place in early 2008. Also the Dr. Gordon s regional survey cruise which will follow this effort in March 2009. 2.3 Previously published research data relating to the project: None 3.

Installations and Equipment Details of installations and equipment (dates of laying, servicing, recovery; exact locations and depth): Satellite remote sensing (sea surface temperature, ocean color) will guide sampling to important features within the Philippine Archipelago. Repeated three-dimensional surveys (using Triaxus, Seasoar or SWIMS) will then characterize the feature. Surveys durations will range from hours to several days, after which a new feature will be chosen and the process repeated.
Sampling will take place within the grey box defined below. Survey location depends on the configuration of mesoscale variability at the time of deployment, so we cannot tell in advance exactly where within the box a given survey will occur. Similarly, we cannot know in advance exactly what times these operations will occur, though we expect all sampling to happen roughly between January and March, 2009. Also, depending on timing, we might recover or deploy Seagliders during this. Should any gliders malfunction during the period of this cruise, we would likely recover the failing instruments. 5. Geographical Areas 5.1 Indicate geographical areas in which the project is to be conducted (with reference in latitude and longitude): We request permission to conduct towed profiler surveys within Philippine waters within the grey shaded areas in the chart attached below. Sampling will likely focus on the region west of Mindoro and Panay, though, time permitting, we respectfully request permission to sample in the Bohol Sea and Surigao Strait (as depicted in the chart). 5.2 Attach chart(s) at an appropriate scale (1 page, high-resolution) showing the geographical areas of the intended work and, as far as practicable, the positions of intended stations, the tracks of survey lines, and the locations of installations and equipment. 6.
