Where do fish go when it freezes outside?

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


Have you ever wondered how fish survive in cold winter weather, or where they go when lakes and ponds freeze over? Like many people, fish tend to be less active in the cold. As cold-blooded creatures, their metabolism dips when temperatures take a dive.

The layer of ice that forms on top of a lake, pond, river, or stream provides some insulation that helps the waterbody retain its heat. Because warm water sinks, freshwater fish often gather in groups near the bottom. Some species, like koi and gobies, may burrow into soft sediments and go dormant like frogs and other amphibians, but most fish simply school in the deepest pools and take a "winter rest."

In this resting state, fishes' hearts slow down, their needs for food and oxygen decrease, and they move about very little. If you've ever gone ice fishing, you know that a long line, a slow, colorful lure, and a hearty portion of patience are often required to land this quiet quarry! Popular ice-fishing species include walleye, northern pike, yellow perch, and rainbow trout.

What is ocean noise?



Ocean noise refers to sounds made by human activities that can interfere with or obscure the ability of marine animals to hear natural sounds in the ocean. Many marine organisms rely on their ability to hear for their survival. Sound is the most efficient means of communication underwater and is the primary way that many marine species gather and understand information about their environment. Many aquatic animals use sound to find prey, locate mates and offspring, avoid predators, guide their navigation and locate habitat, and listen and communicate with each other.

Are we cleared to land? How the Wright Brothers influenced NOAA’s mission.

This item was filled under News


In a span of 12 seconds on December 17, 1903, two men near the town of Kitty Hawk, North Carolina, changed the course of history. This photograph shows the first powered, controlled, sustained flight. Orville Wright at the controls of the machine, lying prone on the lower wing with hips in the cradle which operated the wing-warping mechanism. Wilbur Wright running alongside to balance the machine, has just released his hold on the forward upright of the right wing. Today, we fly using technological advances that the Wright Brothers only could have imagined. Millions of people board airplanes, confident that pilots will guide them safely to their destinations. But safe navigation begins well before the pilot even touches the plane's controls; it begins with the runway. That's where NOAA comes in.

High Tide Bulletin: Winter 2016

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 December 2016 and February 2017. Note: Depending on non-tidal conditions (wind, storms) regions may experience impacts before or after the dates mentioned here.
