NOAA: What is a bight?

A bight is a long, gradual bend or recess in the shoreline that forms a large, open bay. Bights are shallow and may pose hazards to navigation, so their depths, in addition to any submerged features like sand bars and rock formations, are clearly marked on nautical charts.

Watch: Near-normal 2019 Atlantic hurricane season is expected

NOAA’s Climate Prediction Center is predicting ]a near-normal Atlantic hurricane season this year. This outlook expects a 40% chance of a near-normal season, a 30% chance of an above-normal season and a 30% chance of a below-normal season. The hurricane season officially extends from June 1 to November 30.

Explaining High Seas Forecasts

NOAA’s High Seas Forecasts are weather forecasts and data transmitted around the world in real- and near-real-time. These forecasts are aiming to make navigation safer, especially considering the fact that for centuries not much could be done to make shipping safe, because of weather unpredictability.

NOAA: What is GPS

In the past and for centuries, sailors used the constellations, sun, and moon to navigate to distant shores. Today,  all that’s needed is a device called a GPS receiver. GPS stands for Global Positioning System, and it lets us know where we are and where we are going anywhere on Earth.

Explaining what ‘doldrums’ are

What can be described as ‘doldrum’? According to NOAA’s National Ocean Service, ‘doldrums’ is a belt around the Earth that extends about five degrees north and south of the equator. In this area, the prevailing trade winds of the northern hemisphere blow to the southwest. This leads them to collide with the southern hemisphere’s driving northeast trade winds.

NOAA: What are the Totten Beacons

The US  National Ocean Service under the National Oceanic and Atmospheric Administration (NOAA) provided a short overview of what are called Totten Beacons, one of the first aids to navigation which provided safe navigation through the reefs in 19th century.

February 2019 was second wettest month on record for US

This winter was the wettest on record for the US, especially after a steady march of snow and rain storms across the country between December 2018 and the end of February 2019, according to data provided by US NOAA. The wet weather last month also made February 2019 the second wettest February on record.  

USCG, NOAA terminate voyage for illegal fishing in Tortugas Ecological Reserve

The US Coast Guard and National Oceanic and Atmospheric Administration terminated the voyage of the 83-foot commercial fishing vessel ‘Lady Kristie’, with three people aboard Thursday, after discovering multiple violations near Tortugas Ecological Reserve. Fishing in an ecological reserve violates NOAA regulations.

NOAA improves channel depths’ presentation for safer navigation

NOAA’s Office of Coast Survey presented plans to alter the U.S. Army Corps of Engineers (USACE) maintained channel depth values on raster nautical chart products, which include paper nautical charts and the corresponding digital raster navigational charts. Minimum depths (also called controlling depths) are collected during periodic USACE sonar surveys of channels.
