NOAA Sea to Sky: Education resource database

This resource collection from NOAA Education dives into what food webs are. Food webs describe who eats whom in an ecological community. Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly.

This resource collection from NOAA Education explores what oil is, where it comes from, how oil spills can happen, and what NOAA does in response to these events. Oil is an ancient fossil fuel that we use to heat our homes, generate electricity, and power large sectors of our economy. But when oil accidentally spills into the ocean, it can cause big problems. Oil spills can harm sea creatures, ruin a day at the beach, and make seafood unsafe to eat. It takes sound science to clean up the oil, measure the impacts of pollution, and help the ocean recover.

This resource collection from NOAA Education explores where pollution comes from, how it impacts humans and other living things, and what NOAA does to help combat this issue. Each year, billions of pounds of trash and other pollutants enter the ocean. Where does this pollution come from? Where does it go? Some of the debris ends up on our beaches, washed in with the waves and tides. Some debris sinks, some is eaten by marine animals that mistake it for food, and some accumulates in ocean gyres. Other forms of pollution that impact the health of the ocean come from sources like oil spills or from accumulation of many dispersed sources, such as fertilizer from our yards.

This resource collection from NOAA Education explores the chemistry behind ocean acidification and how this impacts living things animals, algae, and ecosystems. In the 200-plus years since the industrial revolution began, the concentration of carbon dioxide (CO₂) in the atmosphere has increased due to human actions. During this time, the pH of surface ocean waters has fallen by 0.1 pH units. This might not sound like much, but the pH scale is logarithmic, so this change represents approximately a 30 percent increase in acidity.

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.

Part of the Faces of the Southeast Fisheries Science Center series, meet Suzana Dumitrita Blake, Ph.D.

Seamounts represent some of Earth’s tallest peaks, unexplored territories, and critical habitats supporting important fisheries across the globe. Students will apply the phenomenon of upwelling and currents to determine why many seamounts sustain diverse ecological communities and support surprising levels of biological productivity in nearby waters. Students analyze data and various models to evaluate how well they represent patterns of ocean currents around seamounts and determine the effects these current flows have on productivity.

Learn more about the intelligent mammals that inhabit our ocean, the problems they face, and their importance in the marine ecosystem. Read to explore NOAA’s efforts to protect dolphin populations and how national marine sanctuaries benefit dolphins.

Learn about one of the ocean’s top predators — sharks — and their critical role in maintaining the marine ecosystem. This collection features NOAA Office of National Marine Sanctuaries resources for everyone to explore NOAA’s efforts to research and conserve shark populations, how sharks support the sanctuary system, and more.
