NASA's Terra satellite passed over Tropical Storm Talim early on Sept. 11 and obtained a visible-light image of the storm as it moved through the Philippine Sea.

As Hurricane Irma approached southern Florida, a NASA satellite captured a night-time image of the storm in the Florida Straits and identified where the strongest storms were occurring within Irma's structure. NOAA's GOES satellite provided a visible image at the time of Irma's landfall in the Florida Keys.

As the Arctic warms twice as fast as the rest of the planet, the range and distribution of at least some fish stocks found in places like the Bering Sea will likely extend northward. That could bring some big changes to the region. More than 60 percent of all seafood caught in the United States comes from the waters off Alaska and generates billions of dollars in revenue each year.

As previously ice-covered areas of the Arctic become seasonally ice-free, there will be pressure to expand US fishing north of the Bering Strait. That can’t happen under the Arctic Management Plan, established in 2009, which prohibits commercial fishing until scientists and fisheries managers understand what’s going on with the ecosystem.

Heatwaves are intensifying in cities due to the double whammy of the urban heat island effect and global warming, according to a new study.

NASA's fleet of satellites have been continually providing forecasters with data on Hurricane Irma. NASA-NOAA's Suomi NPP satellite provided a look at the wide-eye of Irma and if you think about the area of maximum sustained winds around the eye, it's similar to a wide F2 tornado.

NASA's Aqua satellite captured clear view of the eye of Hurricane Jose at it moved toward the Leeward Islands and strengthened into a Category 4 Hurricane on the Saffir-Simpson Hurricane Wind Scale. Aqua also analyzed the storm in infrared light showing powerful storms around the center, capable of heavy rainfall.

Two days of satellite imagery from NASA's Terra and NOAA's GOES East satellites showed that Hurricane Katia was starting to crawl to the coast of southeastern Mexico.   

A global commitment to reduce health risks and environmental damage from mercury pollution came into effect last month (16 August), when the so-called Minamata Convention on Mercuryentered into force.

Hurricane response crews from the U.S. Geological Survey are installing storm-tide sensors at key locations along Florida’s southeast and southwest coastlines in advance of Hurricane Irma.

Under a mission assignment from the Federal Emergency Management Agency, the USGS is currently deploying approximately 58 storm tide sensors, 24 barometers and five rapid deployment gauges, and is consulting with federal and state partners about the need for similar equipment for other coastal areas farther north along the coastlines.

The back deck of the Healy is a tough place to work.  It’s wet, it’s cold, and the scientists slogging away there are always covered in mud.  That’s because getting samples off the bottom of the Chukchi Sea is an important part of our mission this year.
