NOAA Sea to Sky: Education resource database

On the afternoon of April 13, 2018, a large wave of water surged across Lake Michigan and flooded the shores of the picturesque beach town of Ludington, Michigan, damaging homes and boat docks, and flooding intake pipes. Thanks to a local citizen’s photos and other data, NOAA scientists reconstructed the event in models and determined this was the first ever documented meteotsunami in the Great Lakes caused by an atmospheric inertia-gravity wave.

"Sonobuoys" record ocean sounds and are deployed over the side of a ship to send back real-time recordings.

Imagine this: you are sitting on a beautiful beach enjoying a lovely day, when out of the blue an alarm blasts from your phone and reads “Tsunami warning.” Do you know where you would go and what to do? What if you aren’t in the U.S. and there are no alarms, would you know the signs of an approaching tsunami?

Materials like consumer plastics, metals, rubber, paper, textiles, lost fishing gear, vessels, and other lost or discarded items can easily end up in the ocean, where it becomes marine debris. Marine debris threatens the ocean and its resources, the economy, and safe navigation. Animals like turtles, marine mammals, birds, and other creatures can die when they accidentally swallow or get tangled up in marine debris. These materials can also crush sensitive habitats like seagrass beds or coral reefs. All national marine sanctuaries face the challenges of marine debris and the harmful impacts that come along with managing this problem. This collection features resources related to the problem of marine debris, NOAA and sanctuary system programs, and the solution to pollution.

A rapidly changing climate brings challenges to our underwater parks in ways we have never seen before. Climate-related impacts, like changing weather patterns and storm events, warming seas, ocean acidification, and sea level rise, are becoming more prevalent around the globe. Changes in climate will affect national marine sanctuaries and the overall health of the ocean, which is vital to our quality of life and, ultimately, our survival.

Did you know that there are about 120 World War II era aircraft lying at the bottom of Lake Michigan?

SanctSound, a four-year effort led by NOAA, the U.S. Navy, and over 20 partner organizations to better understand the underwater soundscape of the National Marine Sanctuary System. The SanctSound team has been able to gather a wealth of data on the sounds heard in seven national marine sanctuaries and one marine national monument.

A key issue facing hurricane scientists and climate scientists is how Atlantic hurricane activity might be expected to change assuming the climate continues to warm over the coming century.

As Tonga’s Hunga Tonga-Hunga Ha'apai volcano began to erupt on January 15, 2022, it sent more than tsunami waves across the Pacific Ocean — some forms of communications in the region were sent into the dark, too. The eruption broke an underwater communications cable, leaving most of the island nation without internet access and other forms of communication.
