d NOAA and CBI, a 22 N year partnership Prior to becoming an IIQ contractor, CBI performed numerous tasks at the request of CO-OPS. These include installation, maintenance, and/or operation of systems along the entire Gulf Coast in support of PORTS, NWLON, NERRS, and even Joint Hydrographic Surveys projects in Tampico, Mexico. AS an IIQ contractor, CBI s previous projects include: Texas NWLON: Mobile PORTS 2007-2011 Gulfport PORTS 2007-2012 Pascagoula PORTS 2007-2012 Sabine PORTS 2009 - present Houston Galveston PORTS - present Lake Charles PORTS - 2012

CBI &TCOON an integrated observations and operational predictions system Too much data? Approach and computational infrastructure for transition from research/data to actionable information Operational Model Examples: Water Level Forecasting Water temperature predictions for navigation interruption Transit App for ship channel navigation Other examples
February 3-5, 2011 Cold Front Advice for start of traffic Interruption: 2-3 06:00 Advice for end of traffic Interruption: 2-5 18:00 7C 7C 7C 7C
Transit Time Large amount of measurements, nowcasts and predictions for most US ports (PORTS ) Predictions are difficult to access in the field Synthesize and augment predictions/data and make them accessible on a smart phone Transit App developed in collaboration with NOAA CO-OPS
Transit Time Mobile App http://apps.proto.cbi.tamucc.edu/transit/ Indication of the predicted water level Predicted transit time from the start position to that location +4:42 Arrow indicating the strength (length of arrow) and direction of the predicted current if stronger than 0.25 Kts
Other Prediction Tools Water level predictions for the Texas Coast (implemented since ~ 2005) Storm surge predictions for Texas bays (prototype) Local hydrodynamic models (CMS) forced by stations from the dense TCOON network Use dense observation networks to set-up small and computationally efficient local hydrodynamic models

In conclusion The began the development of the Texas Coastal Ocean Observation Network in 1988. Since it s inception, the TCOON has expanded, contracted, stations have been destroyed, and been rebuilt. As a result, data from 30 TCOON stations installed on Storm resistant, hardened structures. ata are available online and in near real-time. CBIs database archives all information and activities associated with each data collection station included in TCOON. For more information, visit: www.cbi.tamucc.edu
