The first-ever 7,300-mile Atlantic Ocean crossing by an unmanned underwater glider is opening up a new world of ocean technology. A ceremony on Dec. 9 in Baiona, Spain, will celebrate the partnership effort among the U.S. interagency Integrated Ocean Observing System (IOOS) through Rutgers University, NOAA, Puertos Del Estado (Spanish Port Authority), the National Oceanographic Partnership Program, and other European partners. “It is through efforts like this that we will continue to learn more about the wonders of the ocean at a critical time for our planet,” said Richard Spinrad, NOAA assistant administrator for oceanic and atmospheric research.

NOAA: North American 2008 Cooling Attributed to Natural Causes

NOAA map

Cooler North American temperatures in 2008 resulted from a strong natural effect, and the overall warming trend that has been observed since 1970 is likely to resume, according to university and NOAA scientists. “Our work shows that there can be cold periods, but that does not mean the end of global warming. The recent coolness was caused by transitory natural factors that temporarily masked the human-caused signal,” said Judith Perlwitz, lead author of the study and a researcher with the Cooperative Institute for Research Environmental Sciences, and NOAA Earth System Research Laboratory.

The 2009 Atlantic hurricane season officially ends today, marking the close of a season with the fewest named storms and hurricanes since 1997 thanks, in part, to El Niño. Commerce’s National Oceanic and Atmospheric Administration (NOAA) reported nine named storms formed this year, including three hurricanes, two of which were major hurricanes at Category 3 strength or higher. These numbers fall within the ranges predicted in NOAA’s mid-season outlook issued in August, which called for seven to 11 named storms, three to six hurricanes, and one to two major hurricanes.

The combined global land and ocean surface temperature was the sixth warmest October on record, according to NOAA’s National Climatic Data Center in Asheville, N.C. Based on records going back to 1880, the monthly National Climatic Data Center analysis is part of the suite of climate services NOAA provides. NCDC scientists reported that the average land surface temperature for October was also the sixth warmest on record. Additionally, the global ocean surface temperature was the fifth warmest on record for October. (More)

NOAA Scientists Undertake In-Flight Study of Global Levels of Greenhouse Gas Distribution

Scientists from Commerce’s National Oceanic and Atmospheric Administration (NOAA) began the second phase of a mission that will provide a detailed view of how carbon dioxide and other greenhouse gases are distributed globally. “Missions such as this one are critical to understanding the impacts of greenhouse gases and particulates,” said Jane Lubchenco, Ph.D., NOAA Administrator. “The data collected are also essential to help verify if policies to reduce these heat trapping pollutants are having their intended effect.” (More)

Representatives from Commerce’s National Oceanic and Atmospheric Administration (NOAA) and the states of North Carolina, South Carolina, Georgia and Florida announced the formation of a partnership to better manage and protect ocean and coastal resources, ensure regional economic sustainability, and respond to disasters such as hurricanes. The announcement was made during the annual meeting of the Coastal States Organization in Charleston, S.C. (More)

New NOAA System Improves Ship Safety, Efficiency, on Lower Mississippi River and Port of New Orleans

Ship captains and pleasure boaters can now get free real-time information on water and weather conditions for the lower Mississippi River from a new NOAA ocean observing system that makes piloting a ship safer and more efficient. The NOAA Physical Oceanographic Real-Time System (PORTS®) on the lower Mississippi River provides observations of tides, currents, water and air temperature, barometric pressure, winds and bridge clearance.

NOAA: El Niño to Help Steer U.S. Winter Weather

El Niño in the central and eastern equatorial Pacific Ocean is expected to be a dominant climate factor that will influence the December through February winter weather in the U.S., according to the 2009 Winter Outlook released by NOAA’s Climate Prediction Center. “We expect El Niño to strengthen and persist through the winter months, providing clues as to what the weather will be like during the period,” says Mike Halpert, deputy director of the Climate Prediction Center. “Warmer ocean water in the equatorial Pacific shifts the patterns of tropical rainfall that in turn change the strength and position of the jet stream and storms over the Pacific Ocean and the U.S.” (More)

NOAA Scientists Study Historic 'Dust Bowl' and Plains Droughts for Triggers

After analyzing historical records and climate model data for two major U.S. droughts in the 1930s and 1950s, scientists from Commerce’s National Oceanic and Atmospheric Administration (NOAA) found two very different causes, shedding new light on our understanding of what triggers drought. Studies such as this one that expand our insights into drought are essential for improving forecasts and can aid in the creation of an early warning system to help communities take precautions and prepare.

September 2009 average temperature for the contiguous United States was above the long-term average, according to NOAA’s monthly State of the Climate report issued today. Based on records going back to 1895, the monthly National Climatic Data Center analysis is part of the suite of climate services NOAA provides. The average September temperature of 66.4 degrees F was 1.0 degree F above the 20th century average. Precipitation across the contiguous United States in September averaged 2.48 inches, exactly the 1901-2000 average. (More)
