NOAA: Warmest Global Sea-Surface Temperatures for August and Summer

NOAA Visualization

The world’s ocean surface temperature was the warmest for any August on record, and the warmest on record averaged for any June-August (Northern Hemisphere summer/Southern Hemisphere winter) season according to NOAA’s National Climatic Data Center in Asheville, N.C. The preliminary analysis is based on records dating back to 1880. NCDC scientists also reported that the combined average global land and ocean surface temperature for August was the second-warmest on record, behind 1998. For the June-August 2009 season, the combined global land and ocean surface temperature was the third-warmest on record. (More)

U.S. Secretary of Commerce Gary Locke and Mayor Jerry Sanders led a groundbreaking ceremony in La Jolla, Calif., for two new buildings dedicated to ocean science on the campus of Scripps Institution of Oceanography at UC San Diego. The project is a major groundbreaking in California under the American Recovery and Reinvestment Act (ARRA). The buildings are supported by two federal agencies—the National Oceanic and Atmospheric Administration (NOAA) and the National Institute of Standards and Technology (NIST)—and will feature state-of-the-art marine life tanks and cutting-edge science labs.

Climate Effects of Atmospheric Haze Better Understood, NOAA Researchers Report

Scientists have used a new approach to sharpen the understanding of one of the most uncertain of mankind’s influences on climate—the effects of atmospheric “haze,” the tiny airborne particles from pollution, biomass burning, and other sources. The new observations-based study led by Commerce’s National Oceanic and Atmospheric Administration (NOAA) confirms that the particles (“aerosols”) have the net effect of cooling the planet—in agreement with previous understanding—but arrives at the answer in a completely new way that is more straightforward, and has narrowed the uncertainties of the estimate.

Jane Lubchenco, Ph.D., Under Secretary of Commerce for Oceans and Atmosphere and National Oceanic and Atmospheric Administration (NOAA) administrator, led a U.S. delegation to Geneva, Switzerland, Aug. 31-Sept. 4 for the World Climate Conference-3 in efforts to establish a Global Framework for Climate Services. This framework is intended to help meet accelerating demands for useful information on the impacts of climate change (Closing Delegation Statement) (Sept. 3 Lubchenco Statement)

NOAA Report Explains Sea Level Anomaly this Summer Along U.S. Atlantic Coast

Persistent winds and a weakened current in the Mid-Atlantic contributed to higher than normal sea levels along the Eastern Seaboard in June and July, according to a new technical report from Commerce’s National Oceanic and Atmospheric Administration (NOAA). After observing water levels six inches to two feet higher than originally predicted, NOAA scientists began analyzing data from select tide stations and buoys from Maine to Florida and found that a weakening of the Florida Current Transport—an oceanic current that feeds into the Gulf Stream—in addition to steady and persistent Northeast winds, contributed to this anomaly.

U.S. Secretary of Commerce Gary Locke announced in Norfolk, Va. $40 million for critical hydrographic survey and chart projects across the United States that strengthen the economy, create jobs, and support safe and efficient marine commerce and trade. Funded by the American Recovery and Reinvestment Act of 2009, the Commerce Department’s National Oceanic and Atmospheric Administration (NOAA) will allocate $32 million to utilize hydrographic surveying contractors to collect data in critical coastal areas which are used to map the seafloor and update nautical charts.

The planet’s ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998, according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880. The July ocean surface temperature departure of 1.06 degrees F from the long-term average equals last month’s value, which was also a record. (More) (National Climatic Data Center) (June Analysis)

Study: Better Observations, Analyses Detecting Short-Lived Tropical Systems

A NOAA-led team of scientists has found that the apparent increase in the number of tropical storms and hurricanes since the late 19th and early 20th centuries is likely attributable to improvements in observational tools and analysis techniques that better detect short-lived storms. The new study shows that short-lived tropical storms and hurricanes, defined as lasting two days or less, have increased from less than one per year to about five per year from 1878 to 2008. (More)

NOAA Joins Other U.S. Agencies and Canada to Survey Arctic Continental Shelf

The Department of Commerce’s National Ocean and Atmospheric Administration (NOAA) will join a multi-agency joint expedition that will bring together icebreakers from the U.S. and Canada to collect and share data useful to both countries in defining the full extent of the Arctic continental shelf. The Arctic survey is part of the multi-year, multi-agency effort undertaken by the U.S. Extended Continental Shelf Project, led by the Department of State, with vice co-chairs from the Department of the Interior and NOAA. NOAA’s Office of Ocean Exploration and Research provided key funding for the U.S. mission. (More)
