NOAA: Deepwater Horizon Incident, Gulf of Mexico Oil Spill Update

Improving weather today allowed both NOAA overflights and dispersant operations to resume. Today, four aircraft applied dispersants to the surface slick, and dispersant application by vessels is expected to begin tomorrow. Monitoring of the dispersant efforts are ongoing. NOAA overflights were conducted over the source as well as south from Mobile. At present, technical specialists and other personnel from many agencies and organizations are assisting NOAA in providing scientific support for the spill response. (Incident News)

NOAA: Deepwater Incident, Gulf of Mexico Effort

Trajectory map--PDF.

The Deepwater Horizon incident declared a Spill of National Significance (SONS). A SONS is defined as "a spill that, due to its severity, size, location, actual or potential impact on the public health and welfare or the environment, or the necessary response effort, is so complex that it requires extraordinary coordination of federal, state, local and responsible party resources to contain and clean up the discharge," and allows greater federal involvement. Commerce’s National Oceanic and Atmospheric Administration (NOAA) is assisting the Unified Command in evaluating a new technique to apply dispersants to oil at the source—5000’ below the surface. If successful, this would keep plumes and sheens from forming. (More) (NOAA-Deepwater) (Trajectory map 1—PDF) (IncidentNews: Deepwater Horizon)

NOAA Awards $73.6 Million Recovery Act Contract for New Fisheries Survey Vessel

Commerce’s National Oceanic and Atmospheric Administration (NOAA) awarded a $73.6 million American Recovery and Reinvestment Act contract to Marinette Marine Corporation located in Marinette, Wisconsin, for the construction of a new fisheries survey vessel, which will dramatically improve NOAA’s ability to conduct surveys for fish, marine mammals and turtles off the U.S. “Thanks to the Recovery Act, this new vessel will greatly enhance our understanding of our ocean resources and play a vital role in supporting NOAA’s mission,” said Jane Lubchenco, Ph.D., Under Secretary of Commerce for Oceans and Atmosphere and NOAA Administrator.” (More)

The eruption of a volcano under the Eyjafjallajokull glacier of Iceland on Wednesday, April 14, sent ripple effects around the globe as it halted international flights to and from Northern Europe. Airborne volcanic ash posed a threat to jet engines, and to prevent disaster, air traffic controllers grounded planes. From the earliest moments of the eruption, a global network of Volcanic Ash Advisory Centers began monitoring the ash plume and the appropriate centers issued advisories about flow of the ash through the atmosphere. There are nine such centers, each responsible for a defined geographic region. (More) (Video clip) (Image of ash cloud)

NOAA: Global Temps Push Last Month Hottest March on Record

The world’s combined global land and ocean surface temperature made last month the warmest March on record, according to Commerce’s National Oceanic and Atmospheric Administration (NOAA). Taken separately, average ocean temperatures were the warmest for any March and the global land surface was the fourth warmest for any March on record. Additionally, the planet has seen the fourth warmest January-March period on record. The monthly National Climatic Data Center analysis, which is based on records going back to 1880.

NOAA’s State of the Climate report shows the March 2010 average temperature for the entire contiguous United States was warmer-than-average with several New England states experiencing one of the warmest March’s on record. Average precipitation for the U.S. was below normal, but heavy rainfall set March records in parts of the Northeast. Based on data going back to 1895, the monthly analyses are prepared by scientists at NOAA’s National Climatic Data Center in Asheville, North Carolina. (More) (Temperatures) (Precipitation levels)

NOAA's GOES-15 Weather Satellite Captures Its First Image of Earth

GOES-15, launched on March 4 from Cape Canaveral, Florida, joins three other NOAA operational GOES spacecraft that help the agency's forecasters track life-threatening weather—from tornadoes, floods and hurricanes—and solar activity that can impact the satellite-based electronics and communications industry. The black and white full-disk image shows North and South America with a storm system visible across the United States, indicated by a drape of clouds from New England westward to the central Plains. Further west is a cold front over the Rocky Mountains. Mostly clear skies are seen over the mid-Atlantic, southeastern U.S., Gulf of Mexico, California and Mexico. (More)

Norfolk, Va.-based NOAA Ship Thomas Jefferson to Map Ocean Floor in Gulf of Mexico

Commerce’s NOAA Ship Thomas Jefferson, one of the most technologically advanced hydrographic survey vessels in the world, will depart its Norfolk, Va. homeport on April 6 to conduct a five-month long effort to map the seafloor and look for hazards to navigation off the Gulf coast. “The Gulf of Mexico has been affected by a number of large hurricanes in recent years, and our work will pinpoint the resulting hazards and shoals in these busy waters,” said Cmdr. Shepard Smith, Thomas Jefferson’s commanding officer. (More)

50th Anniversary of the Satellite that "Forever Changed Weather Forecasting"

One of the first satellite images. Click for a full version.

Fifty years ago today, the world’s first weather satellite lifted off from Cape Canaveral, Fla., and opened a new and exciting dimension in weather forecasting. Top leaders from Commerce’s NOAA and NASA hailed the milestone as an example of their agencies’ strong partnership and commitment to flying the best satellites today and beyond. The first image from the satellite, known as TIROS-1, was a fuzzy picture of thick bands and clusters of clouds over the United States. An image captured a few days later revealed a typhoon about 1,000 miles east of Australia. TIROS-1, a polar-orbiting satellite, weighed 270 pounds and carried two cameras and two video recorders.

NOAA: Sixth-Warmest February in Combined Global Surface Temperature, Fifth-Warmest December-February

Last month’s combined global land and ocean surface temperature made it the sixth-warmest February ever recorded. Additionally, the December 2009-February 2010 period was the fifth-warmest on record averaged for any similar three-month Northern Hemisphere winter-Southern Hemisphere summer season, according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C. Based on records going back to 1880, the monthly NCDC analysis is part of the suite of climate services NOAA provides to businesses, communities and governments so they may make informed decisions to safeguard their social and economic well-being.
