An Inch of Water. What’s it Worth?

This item was filled under [ News ]


Our nation’s ports are the lifelines of our economy. In 2016, foreign trades through U.S. ports were valued at $1.5 trillion—$475 billion exports and $1.0 trillion imports were moved by vessels. When goods travel through ports, it means they are traveling via ship.

NOS is in the business of making sure that mariners—and the goods they are transporting—make it to their destinations safely and quickly. Just as airplane pilots need to know current weather and ground conditions, ship captains need to know exactly what's going on in the water and in the air. NOS monitoring systems supply mariners with the real-time data they need, providing information such as water levels, wind and current speeds and directions, and water temperature. But what does this have to do with that inch of water?

Understanding Sea Level Rise in the Nation’s Largest Estuary

This item was filled under [ News ]


Chesapeake Bay Sentinel Site Cooperative researchers are working towards a better understanding of how the nation's largest estuary is changing over time due to rising sea levels. Scientists are collecting data with tide stations and other tools at sentinel sites around the Bay. Through intensive studies and long-term observations at these stations, Cooperative partners are helping to create a clearer picture of sea level and ecological changes in this region to better inform coastal decision-makers about the health of the Bay now and into the future.

Deepwater Horizon Oil Spill: Longterm Effects on Marine Mammals, Sea Turtles

This item was filled under [ News ]


A recent Endangered Species Research special issue summarizes some of the devastating longterm effects of the Deepwater Horizon oil spill on protected marine mammals and sea turtles. The issue compiles 20 scientific studies authored by NOAA scientists and partners covering more than five years' worth of data collection, analysis, and interpretation. The research indicates that populations of several marine mammal and sea turtle species will take decades to rebound. Significant habitat restoration in the region will also be needed.

NOAA scientists used a variety of cutting-edge research methods in these studies and many others as part of a Natural Resource Damage Assessment. This is the legal process where we investigate the type of injuries caused by the oil spill, quantify how many animals were harmed, develop a restoration plan to compensate for the natural resource injuries, and hold responsible parties liable to pay for the restoration.

The Rebirth of a Healthy Eelgrass Meadow

This item was filled under [ News ]


An effort to restore eelgrass beds along Virginia's eastern shore began with people painstakingly planting 200 acres of eelgrass seeds by hand. Today, these eelgrass meadows have grown to 6,195 acres — providing a home for an estimated 240,000 bay scallops.

Sea Urchins Help Combat Invasive Algae on Corals

This item was filled under [ News ]


Tiny sea urchins are helping to combat invasive algae in Kaneohe Bay—part of a restoration plan from the settlement of the 2005 grounding of the ship M/V Cape Flattery on the coral reefs south of Oahu. The grounding, and response efforts to free the ship, injured 19.5 acres of coral. Despite the injuries, the reef began recovering on its own. Rather than mess with that natural recovery, NOAA Fisheries, U.S. Fish and Wildlife Service, and Hawaii's Division of Aquacitec Resources focused on restoring coral reefs in Kaneohe Bay.

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.
