First up, improving charts and geodesy for Straits of Florida
Coast Survey welcomed Cuban colleagues to NOAA offices this week, as representatives of Cuba’s National Office of Hydrography and Geodesy (ONHG) traveled to Maryland for the first time since last December. In March, NOAA and ONHG signed a Memorandum of Understanding in Havana.
“We’ve identified a broad sweep of navigation issues for collaboration, and we’ve started to produce tangible results,” said Dr. Russell Callender, assistant administrator of NOAA’s National Ocean Service, at the start of three days of work sessions. “On behalf of NOAA, I’d like to express my appreciation for the progress made by our two agencies.”
The MOU, which is focused on improving maritime navigation safety and related areas of mutual interest to protect lives and property at sea, is the framework for continuing consultations between NOAA’s National Ocean Service and ONHG.
“The collaboration between our two countries is the way to move forward,” said Dr. Candido Alfredo Regalado Gomez, chief of Cuba’s National Office of Hydrography and Geodesy. “We are here to work.”
Among other hydrographic discussions, representatives from both agencies will review, revise, and hopefully approve a planned new international chart (INT chart 4149), the first cooperative charting product between the United States and Cuba during the modern era. NOAA expects to release the new chart in mid-December, at a meeting in Brazil of hydrographic officials from the Western Hemisphere. The chart covers south Florida, the Bahamas, and north Cuba, a popular area for both recreational boaters and commercial mariners.
The publication of the new international chart, along with alignment of U.S. and Cuba electronic navigational charts, will resolve many navigational issues as vessels move across the shared maritime border.
In addition to charting, the U.S.-Cuba dialogue has expanded to include an emerging geodetic component. NOAA’s National Geodetic Survey will discuss current datums (North American Datum of 1983 and North American Vertical Datum of 1988) and plans to transition to new datums by 2022. Discussions include both geometric (latitude and longitude) and geopotential (vertical coordinate referenced to Earth’s mean sea level) issues.
Representatives from both agencies have expressed additional interest in tide and current monitoring, modeling, and forecasting. The exchange of data and information will improve the accuracy and quality of these products, as closer direct dialogue between Cuban and NOAA hydrographic offices promises to improve navigation safety in the Florida Straits, the Gulf of Mexico and the wider Caribbean.
