Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae| oceanservice.noaa.gov
A team of NOAA and university sea level rise experts completed a study verifying the accuracy of NOAA’s modeling of historical coastal water level information for areas along the Atlantic and Caribbean coasts and the Gulf of Mexico.| oceanservice.noaa.gov
High tides do not coincide with the location of the moon. Tides originate in the ocean and progress toward the coastlines, where they appear as the regular rise and fall of the sea surface. Thanks to Sir Isaac Newton’s 1687 discovery, we know that tides are very long-period waves that move through the ocean in response to forces exerted by the moon and sun. However, these gravitational forces do not control when high or low tide events occur. Other forces, more regional than the moon or sun...| oceanservice.noaa.gov

Plastic is everywhere: In your home, your office, your school — and your ocean. Among the top 10 kinds of trash picked up during the 2017 International Coastal Cleanup were food wrappers, beverage bottles, grocery bags, straws, and take out containers, all made of plastic.| oceanservice.noaa.gov
Sea water has been defined as a weak solution of almost everything. Ocean water is a complex solution of mineral salts and of decayed biologic matter that results from the teeming life in the seas.| oceanservice.noaa.gov
Microplastics are small plastic pieces less than five millimeters long which can be harmful to our ocean and aquatic life.| oceanservice.noaa.gov
PCBs, or polychlorinated biphenyls, are industrial products or chemicals| oceanservice.noaa.gov
Eutrophication is a big word that describes a big problem in the nation's estuaries. Harmful algal blooms, dead zones, and fish kills are the results of the eutrophication process—which begins with the increased load of nutrients to estuaries and coastal waters.| oceanservice.noaa.gov
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white.| oceanservice.noaa.gov
El El Nino and La Nina are complex weather patterns resulting from variations in ocean temperatures in the Equatorial Pacific.| oceanservice.noaa.gov
