Chemical products like household cleaners, pesticides, paints and perfumes that contain compounds refined from petroleum now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study

Unique collaboration works to extend sea ice prediction from days to decades

For more than two decades, Elizabeth Hunke has worked at the Department of Energy’s Los Alamos National Laboratory to design, create and improve a model used to predict sea ice extent, thickness and movement in both the Arctic and Antarctica. From the beginning, Hunke understood that collaboration was the key to improving this model. At a time when sea ice prediction is needed more than ever, NOAA, the Navy and other agencies are working together to extend sea ice prediction from days to decades.

PORTLAND — Scientists have for the first time captured the sounds of snapping shrimp off the Oregon coast and think the loud crackling from the snapping of their claws may serve as a dinner bell for eastern Pacific gray whales, according to new research by NOAA and Oregon State University presented here today. 

New research reveals patterns of US and global ozone pollution

Despite significant gains in controlling ground-level ozone pollution, some residents of California, Arizona, Colorado, Texas, the Midwest and the Mid-Atlantic spent more than 15 days each year between 2010 and 2014 breathing unhealthy levels of pollution, according to information from a new global database developed with NOAA support.

This summer, NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) hosted 10 interns, ranging from a high school senior to graduate students well on their way to their Ph.D. degrees. Each intern conducted research relevant to GFDL’s climate-science mission, and most presented their findings at GFDL and at their home institutions.

Since hitching unsolicited rides in boat ballast water in the late 1980s, invasive quagga mussels (Dreissena rostriformis bugensis), which are native to Ukraine, have caused massive changes to the ecology of the Great Lakes.  These invasive mussels have also taken a toll on the Great Lakes recreational and commercial fisheries, which are valued at $4-7 million annually.

What’s the first thing that comes to mind when you hear the words carbon dioxide? Is it the ocean? In this day and age, it should be. The ocean absorbs about one fourth of the extra carbon dioxide in the air that is released through human activity, according to a researcher at Scripps Institution of Oceanography.

Phytoplankton - tiny plant-like organisms drifting through the great, vast ocean - are barely visible to the naked eye, and some are visible only through a microscope. Yet, when they are thriving, it is possible to see them from as far away as space. Their location is marked by swirling patterns of bright blues and greens that give the ocean a slick, marbled appearance, like oil on water.
