NOAA Sea to Sky: Education resource database

Meteorologists at NOAA’s National Weather Service have always monitored the conditions of the atmosphere that impact the weather, but over time the equipment they use has changed. As technology advanced, our scientists began to use more efficient equipment to collect and use additional data. These technological advances enable our meteorologists to make better predictions faster than ever before.

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.

Keeping our marine transportation system functioning in a way that is safe and efficient requires information about water depth; mapping the shape of the seafloor, lakebed, or coastline; pinpointing the location of possible obstructions; and understanding many other physical features of water bodies. Hydrography is the science behind this information, and surveying is a primary method of obtaining hydrographic data. In this episode, we learn about surveying and NOAA Ship Thomas Jefferson's survey missions in the Great Lakes.

Millions of people rely on the Great Lakes for recreation, industry, and drinking water. Changing water levels can have positive or negative impacts on industries like tourism and transportation in the region. At present, anthropogenic climate change is affecting precipitation events and temperatures throughout the Basin and future predictions suggest this will continue. While it is presently unknown how water levels will change in the Great Lakes Basin, it is important to continue to monitor them as they are an integral part of life in the Great Lakes Basin.

Ever since Thunder Bay National Marine Sanctuary was designated in 2000 as the first national marine sanctuary in the Great Lakes, staff and partners have undertaken several expeditions to search for shipwrecks, and have even discovered some that were lost for decades. Probably one of the most notable discoveries within the sanctuary since designation is that of the steamer Choctaw (1892-1915) and wooden bulk freighter Ohio (1873-1894) in historic shipping lanes off Presque Isle, Michigan in Lake Huron.

The 6+ miles wide asteroid that hit Earth 66 million years ago, widely accepted to have wiped out nearly all the dinosaurs and roughly three-quarters of the planet’s plant and animal species, also triggered a megatsunami with mile-high waves. Recent historical tsunamis pale in comparison with this globally catastrophic event, thought to be 30,000 times more initial energy than any recorded events. Watch this visualization of this tsunami as it spans the entire ocean.

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.
