News Highlights

There's a lot going on at NOAA's National Ocean Service.

One of three online Gulf of Mexico harmful algal bloom products now available to the public, the respiratory irritation forecast displays conditions at individual beaches over the next 30 hours. It is updated every three hours with any new information and supported by volunteer citizen scientists. Respiratory irritation risk is indicated by the color of the pins: blue (absent or low risk), yellow (low risk), orange (moderate risk), and red (high risk).
Now Available: Enhanced Gulf of Mexico Harmful Algal Bloom Forecasting Products

NOAA’s newly enhanced harmful algal bloom forecasts are now available to the public in real time. The forecasts are higher resolution, providing hourly observations at the individual beach level. Analysis of "red tide" algal bloom locations and reported impacts are now automated, and reports include forecasts of potential development, intensification, transport, and impacts of algal blooms.

A container ship enters the shipping channel at PortMiami, where vessel pilots now have access to real-time current information to help guide them safely into port. This NOAA system, called PORTS® (short for Physical Oceanographic Real-Time System), is deployed in many busy waterways throughout the U.S. to provide key environmental parameters — including water levels, currents, waves, salinity, bridge clearance (air gap), winds, air and water temperature, and visibility. Sensors are tailored to meet specific needs at each seaport.
NOAA Celebrates 30 Years of Safer Marine Navigation Through PORTS®

This July, PORTS celebrates 30 years of providing commercial vessel operators with accurate and reliable real-time environmental conditions to enhance the safety and efficiency of maritime commerce.
