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.

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.

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.

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.

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.

Now they are waiting on laboratory confirmation that the genetic samples they collected prove this is a rare find, indeed. It is a story that could solve a decades old mystery. The footage from an expedition off Cape Horn, Chile, documented a new type of killer whale with different appearance. Researchers obtained a tiny bit of tissue/blubber that will allow them to determine if the “Type D” whales are a new species.

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’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.

NOAA’s Office of Coast Survey announced its plans to change the US Army Corps of Engineers maintained channel depth values on raster nautical chart products, which include paper nautical charts and the corresponding digital raster navigational chart. The change from showing, often outdated, controlling depths, to showing channel project depths on raster nautical chart products, will provide more clarity and safety for mariners.

Scientists with the National Centres for Environmental Information (NCEI) have made an early update to World Magnetic Model (WMM) concerning the unpredictable move from Canada Arctic towards Siberia. Most of the times, an updated version of WMM is published every five years and the scheduled date for new updates was at the end of 2019.
