o Support the continued operation of the campaign's decadal duration of the Yucatan Channel, Florida Straits, and Campeche Banks mooring arrays (shown in teal in Figure 4.2; see Recommendations 9 and 12) o Deploy a West Florida Shelf real-time "pressure point" mooring (shown as a blue star in Figure 4.2; see Recommendation 15)

FIGURE 4.2 Near-term observational scheme. NOTE: Red ovals indicate recommended HF radar installations, the blue grid indicates the general area of bottom-moored array, teal lines indicate existing mooring locations from which data, historic and future, should be accessed, and the blue star indicates location of West Florida Shelf "pinch point" mooring.

The committee recommends these measures: • Improved predictive skill in forecasting the LC and/or LCE current speed, verti cal structure, and duration out to a forecast period of days to 1 week • Improved predictive skill in forecasting the extension of the LC (location and duration) and LCE propagation out to a forecast period of approximately 1 month 66

The funding opportunity should be solicited for a 5-year period with the opportunity to document progress and propose a 5-year extension after approximately 3.5 years have elapsed. Key Observation Variables The funding opportunity should principally specify observing temperature, salinity, current vectors, and pressures from the surface through the entire water column and fundamental near-surface meteorological variables.

• Surface current data from newly procured and/or installed and operated HF radars on three oil/gas platforms in the western Gulf, and on land sites cover ing the inflow/outflow regions (see Recommendations 3, 10, and 11)

. Technology Enhancements The funding opportunity should strongly encourage and incentivize proposals that commit to the adoption of vehicle, sensor, and data communication technology enhancements.

Opportunites for collaboration are highlighted in Box 4.1. The campaign solicitation should reach out to talented ocean scientists and numerical modelers in • academia; • nonprofit organizations that work in the ocean observing and modeling fields (e.g., Navy University Affiliated Research Centers [UARCs]

We also share the Florida Straits with the Bahamas. While the campaign should encourage -- to the point of funding -- collaboration with our Gulf neighbors, the GRP should, in the near term, begin discussions about data sharing and the furthering of moorings operations, HF radar installation, and other ocean observing plans.

Additionally, any funding opportunity should explicitly require a data manager or data management team to ensure proper capacity for adhering to the data management policy. Regarding systems for data communication, quality control, and archival and access, the funding oppor unity should encourage the use of IOOS protocols and other existing, acces t sible, nationally accepted data management systems (e.g., those used by NDBC)

The committee believes that success in any model is dependent on the technical quality of the team selected and especially the quality of overall program leadership. The committee recommends that scientific/technical program principal investigators and science teams be selected based on track record, experience, and collaborative potential by a GRP selection panel.

ESTIMATED COSTS The Statement of Task specifically asks for an estimate of the costs associated with the campaign components. The estimated costs described below do not consider contributions of outside funding or in-kind resources possibly contributed through collaborative leveraging.
