NOAA releases manual to inform deepwater exploration mapping NOAA releases manual to inform deepwater exploration mapping The NOAA Office of Ocean Exploration (OER) has released the NOAA OER Deepwater Exploration Mapping Procedures Manual to describe the office’s approach to deepwater ocean exploration acoustic mapping. OER is sharing this manual as a contribution to broader cross-agency efforts to develop standard ocean mapping protocols and to serve as a guide for other interested public and private entities conducting deepwater mapping and exploration.

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020 7Apr2021 Read more The global average carbon dioxide level in the atmosphere surged at the fifth-highest rate in NOAA's 63-year record during 2020. Preliminary estimates of the increase in methane levels indicate it may have been the largest annual jump on record. Read more
Climate-driven shifts in deep Lake Michigan water temperatures signal the loss of winter 16Mar2021 Read more Climate change is causing significant impacts on the Great Lakes and the surrounding region. As the largest surface freshwater system in the world, the Great Lakes have an enormous impact, seen and unseen, on the more than 34 million people who live within their collective basin. Because of their unique response to environmental conditions, Earth’s large lakes are considered by scientists as key sentinels of climate change. A long-term study published in Nature Communications today from NOAA reveals a warming trend in deepwater temperatures that foreshadows profound ecological change on the horizon. While less visible than the loss in ice cover and increasing lake surface temperatures, this latest index of climate change adds to the growing evidence of climate change impacts in the region.

NOAA projects 30-percent maximum Great Lakes ice cover for 2021 winter 21Jan2021 Read more NOAA scientists project the maximum Great Lakes ice cover for 2021 will be 30 percent, higher than last year’s maximum of 19.5 percent, but part of a long-term pattern of declining ice cover likely driven by climate change.

New study shows promise of forecasting meteotsunamis 31Mar2021 Read more On the afternoon of April 13, 2018, a large wave of water surged across Lake Michigan and flooded the shores of the picturesque beach town of Ludington, Michigan, damaging homes and boat docks, and flooding intake pipes. Thanks to a local citizen’s photos and other data, NOAA scientists reconstructed the event in models and determined this was the first ever documented meteotsunami in the Great Lakes caused by an atmospheric inertia-gravity wave.

Emissions of a banned ozone-depleting gas are back on the decline 10Feb2021 Read more New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.
