Healthy coastal ecosystems play crucial roles in the U.S. economy, from supporting multibillion-dollar fisheries and tourism industries to protecting coastlines from storms.Theyre also difficult to manage, requiring specialized knowledge and technology.Thats why the National Oceanic and Atmospheric Administrationthe federal agency best known for collecting and analyzing the data that make weather forecasts and warnings possibleleads most of the governments work on ocean and coastal health, as well as research into the growing risks posed by climate change.The government estimates that NOAAs projects and services support more than one-third of the nations gross domestic product. Yet, this is one of the agencies that the Trump administration has targeted, with discussions of trying to privatize NOAAs forecasting operations and disband its crucial climate change research.As a marine environmental historian who studies relationships among scientists, fishermen, and environmentalists, I have seen how NOAAs work affects American livelihoods, coastal health, and the U.S. economy.Here are a few examples from just NOAAs coastal work, and what it means to fishing industries and coastal states.Preventing fisheries from collapsingOne of the oldest divisions within NOAA is the National Marine Fisheries Service, known as NOAA Fisheries. It dates to 1871, when Congress created the U.S. Commission of Fish and Fisheries. At that time, the first generation of conservationists started to worry that Americas natural resources were finite.By conducting surveys and interviewing fishermen and seafood dealers, the fish commissioners discovered that freshwater and saltwater fisheries across the country were declining. Oil spills and raw sewage were polluting waterways. Fishermen were using high-tech gear, such as pound nets, to catch more and more of the most valuable fish. In some areas, overfishing was putting the future of the fisheries in jeopardy.One solution was to promote aquaculture, also known as fish or shellfish farming. Scientists and entrepreneurs reared baby fish in hatcheries and transferred them to rivers, lakes, or bays. The Fish Commission even used refrigerated railroad cars to ship fish eggs across the country.Today, U.S. aquaculture is a US$1.5 billion industry and the worlds fastest-growing food sector. Much of the salmon you see in grocery stores started as farm-raised hatchlings. NOAA provides training, grants, and regional data to support the industry.NOAA Fisheries also helps to regulate commercial and recreational fishing to keep fish populations healthy and prevent them from crashing.The 1976 Magnuson-Stevens Fishery Conservation and Management Act and other laws implemented catch limits to prevent overfishing. To develop fair regulations and combat illegal practices, NOAA and its predecessors have worked with fishing organizations through regional fishery management councils for decades.These industries generate $321 billion in sales and support 2.3 million jobs.Restoring coral reefs to help marine life thriveNOAA also benefits U.S. coastal communities by restoring coral reefs.Corals build up reefs over centuries, creating cities of the sea. When theyre healthy, they provide nurseries that protect valuable fish species, like snapper, from predators. Reefs also attract tourism and protect coastlines by breaking up waves that cause storm-driven flooding and erosion.The corals of Hawaii, Florida, Puerto Rico, and other tropical areas provide over $3 billion a year in benefits from sustaining marine ecosystems to recreation, including sport fishing.However, reefs are vulnerable to pollution, acidification, heat stress, and other damage. Warming water can cause coral bleaching events, as the world saw in 2023 and 2024.NOAA monitors reef health. It also works with innovative restoration strategies, such as breeding strains of coral that resist bleaching, so reefs have a better chance of surviving as the planet warms.Battling invasive species in the Great LakesA third important aspect of NOAAs coastal work involves controlling invasive species in Americas waters, including those that have menaced the Great Lakes.Zebra and quagga mussels, spiny water flea, and dozens of other Eurasian organisms colonized the Great Lakes starting in the late 1900s after arriving in ballast water from transoceanic ships. These invaders have disrupted the Great Lakes food web and clogged cities water intake systems, causing at least $138 million in damage per year.In the Northwest Atlantic, Caribbean and Gulf of Mexico, invasive lionfish, native to Asia and Australia, have spread, preying on native fish essential to coral reefs. Lionfish have become one of the worlds most damaging marine fish invasions.NOAA works with the Coast Guard, U.S. Geological Survey, and other organizations to prevent the spread of invasive aquatic species. Stronger ballast water regulations developed through the agencys research have helped prevent new invasions in the Great Lakes.Understanding climate changeOne of NOAAs most crucial roles is its leadership in global research into understanding the causes and effects of climate change.The oil industry has known for decades that greenhouse gases released into the atmosphere from burning fossil fuels would raise global temperatures.Evidence and research from around the world have connected greenhouse gas emissions from human activities to climate change. The data have shown how rising temperatures have increased risks for coastal areas, including worsening heat waves and ocean acidification that harm marine life; raising sea levels, which threaten coastal communities with tidal flooding and higher storm surges; and contributing to more extreme storms.NOAA conducts U.S. climate research and coordinates international climate research efforts, as well as producing the data and analysis for weather forecasting that coastal states rely on.Why tear apart an irreplaceable resource?When Republican President Richard Nixon proposed consolidating several different agencies into NOAA in 1970, he told Congress that doing so would promote better protection of life and property from natural hazards, better understanding of the total environment, and exploration and development leading to the intelligent use of our marine resources.The Trump administration is instead discussing tearing down NOAA. The administration has been erasing mentions of climate change from government research, websites, and policiesdespite the rising risks to communities across the nation. The next federal budget is likely to slash NOAAs funding.Commercial meteorologists argue that much of NOAAs weather data and forecasting, also crucial to coastal areas, couldnt be duplicated by the private sector.As NOAA marks its 55th year, I believe its in the nations and the U.S. economys best interest to strengthen rather than dismantle this vital agency.Christine Keiner is a chair at the Department of Science, Technology, and Society at Rochester Institute of Technology.This article is republished from The Conversation under a Creative Commons license.
