High Tide Bulletin: Spring 2017 (March – May)

This item was filled under News


The rising and falling of the sea is a phenomenon upon which we can always depend. Tides are the regular rise and fall of the sea surface caused by the gravitational pull of the moon and sun and their position relative to the earth.There are some factors that cause the tides to be higher than what is "normally" seen from day to day. This bulletin tells you when you may experience higher than normal high tides for the period of time between March and May 2017.

NOAA Releases 2017 Hydrographic Survey Season Plans

This item was filled under News


Coast Survey maintains over a thousand charts and publications covering 95,000 miles of shoreline and 3.4 million square nautical miles of water. Measuring depths and determining new dangers to navigation along U.S. coasts and the Great Lakes is a monumental job because the seafloor is constantly changing due to factors such as storms, erosion, and development. One of Coast Survey's biggest tasks during the winter months is to plan hydrographic survey projects for the coming field season. View 2017 planned survey projects.

From Ridge to Reef: Habitat Conservation in Puerto Rico

This item was filled under News


The picturesque hillsides and vibrant blue waters of northeast Puerto Rico and nearby Culebra Island are home to marine and terrestrial ecosystems that make it a truly special place. This corner of Puerto Rico is NOAA's only Habitat Blueprint Focus Area in the Caribbean. NOAA's Habitat Blueprint is a national framework to improve habitat for fisheries, marine life, and coastal communities. Among the most pressing environmental issues here are the impacts from soil erosion and nonpoint source pollution on the coral reefs and other marine habitats that lie just offshore from the rugged hillsides.

What are the Roaring Forties?



During the Age of Sail (circa 15th to 19th centuries), these strong prevailing winds propelled ships across the Pacific, often at breakneck speed. Nevertheless, sailing west into heavy seas and strong headwinds could take weeks, especially around Cape Horn at the southern tip of South America, making it one of the most treacherous sailing passages in the world. The Roaring Forties take shape as warm air near the equator rises and moves toward the poles. Warm air moving poleward (on both sides of the equator) is the result of nature trying to reduce the temperature difference between the equator and at the poles created by uneven heating from the sun.

How the arrival of containers and intermodalism revolutionized the shipping industry. As container ships continue to grow in size and ports grow more congested by the year, NOAA plays an increasingly critical role in U.S. marine transportation. NOAA services and products improve the efficiency of ports and harbors, promote safety, and help to ensure the protection of coastal marine resources.

What is the Pineapple Express?

This item was filled under Facts, Ocean Observations, Ocean Science


Atmospheric rivers are narrow regions in the atmosphere that transport much of the moisture from the tropics to northern latitudes. Atmospheric rivers are part of the Earth's ocean water cycle, and are tied closely to both water supply and flood risks.

A well-known example of a strong atmospheric river is called the "Pineapple Express" because moisture builds up in the tropical Pacific around Hawaii and can wallop the U.S. West Coast with heavy rainfall.

Are all fish cold-blooded?

This item was filled under Basics, Ecosystems, Facts, Ocean Life


Not all fish are cold-blooded. In 2015, researchers with the NOAA Southwest Fisheries Science Center revealed the opah, or moonfish, as the first fully warm-blooded fish. Although not as warm as mammals and birds, the opah circulates heated blood throughout its body, giving it a competitive advantage in the cold ocean depths from 150 to 1,300 feet below the surface.

NOAA designates 29th National Estuarine Research Reserve

This item was filled under News


On Jan. 19 , NOAA announced the establishment of the He'eia National Estuarine Research Reserve. Estuarine reserves protect a section of an estuary and provide a living laboratory to explore and understand the important areas where rivers meet the sea. The 1,385-acre He'eia National Estuarine Research Reserve encompasses upland forests and grasslands, wetlands, reefs and seagrass beds, as well as the largest sheltered body of water in the Hawaiian Island chain. It is located within the Kaneohe Bay estuary on the windward side of Oahu and includes significant historic and cultural resources.
