Intra-Americas Sea Trials
SSH forecast for 21 Jan 2007 from the ROMS modeling system, run in real-time on board the Royal Caribbean International vessel Explorer of the Seas. The black line shows the vessel’s cruise path.
• University of California, Santa Cruz researchers assimilating CCAR SSH into a Regional Ocean Modeling System (ROMS) for data assimilation and ocean prediction in the IAS, emphasizing the Caribbean Sea.• Partners: University of Miami, NOAA, NSF, Royal Caribbean Cruise Line• Cruise ship, Explorer of the Seas, equipped with oceanic and atmospheric sensors, for continuous observation along two cruise tracks that circumnavigate the Caribbean Sea once every two weeks.• Sea trials on board the Explorer during January and February 2007.•http://marine.rutgers.edu/po/ias

Hilton’s Realtime Navigator
CCAR SSH and ocean color overlay hosted by the Realtime-Navigator website.
• Private company provides fishing charts and atlas
• Large game fish (marlin, tuna)
• Offshore Gulf of Mexico
• Altimeter and ocean color data maps provided via CCAR
• CCAR produces daily sea surface height and chlorophyll concentration maps (MODIS) for 10 regions in the Gulf and along the Atlantic Coast.

Ocean color & SSH view ocean eddies
A. Fong, U. Hawaii
Hindcast SSH contours on chlorophyll concentration (MODIS). Note anticyclonic eddy with high chlorophyll concentration.
• U. Hawaii at Manoa researcher studies the spatial and temporal abundances of nitrogen-fixing bacteria
• May play an important role in open-ocean biogeochemical cycling
• SSH + MODIS data (from CCAR) in region of enhanced chlorophyll north of Oahu
• The feature was coincident with the decay of an anti-cyclonic eddy.
• NRT and hind-cast data allowed tracking and sampling of the feature for both biogeochemical and biological parameters.
• Progression of this and similar feature was tracked, providing compelling evidence for increased productivity due to these mesoscale features.
