The coronavirus pandemic response has reduced pollution from a large number of sources across many geographic regions. NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing, and other activities on Earth's atmosphere and oceans. Researchers are using the most advanced atmosphere-ocean models to look for changes in atmospheric composition, weather, climate, and precipitation over weeks to months. In the oceans, NOAA scientists will be assessing impacts of reduced underwater noise levels on marine life.
PMEL along with NOAA Fisheries Office of Science and Technology, NOAA Sanctuaries and Department of Interior’s National Park Service are collaborating to analyze data from hydrophones deployed around the United States coastal waters to measure changes and assess any impacts on fisheries and marine mammal activity due to reduced maritime transportation and other maritime activities.
