NASA study reveals Oceans Temperature Rise Slowed

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new NASA study of ocean temperature measurements shows that in recent years, extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans. Researchers say this shifting pattern of ocean heat accounts for the slowdown in the global surface temperature trend observed during the past decade.

Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory, Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized.

NASA Soil Moisture Active Passive (SMAP) observatory starts three year mission

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s new Soil Moisture Active Passive (SMAP) mission to map global soil moisture and detect whether soils are frozen or thawed has begun science operations.

Launched January 31st on a minimum three-year mission, SMAP will help scientists understand links among Earth’s water, energy and carbon cycles; reduce uncertainties in predicting climate; and enhance our ability to monitor and predict natural hazards like floods and droughts. SMAP data have additional practical applications, including improved weather forecasting and crop yield predictions.

The map has a resolution of 5.6 miles (9 kilometers). The data gap is due to turning the instruments on and off during testing. (NASA/JPL-Caltech/GSFC)

Chikungunya Virus Disease Spread by Bites

Tennessee Department of Health - TDOHNashville, TN – The Tennessee Department of Health is reminding vacation and business travelers about the importance of protecting themselves from mosquitoes that may transmit chikungunya virus and other mosquito-borne illnesses like dengue.

The first confirmed case of chikungunya virus disease in Tennessee occurred in 2014; since then 42 additional cases have been documented, all involving travel outside the state.

Tennessee Department of Agriculture reports additional Tennessee counties quarantined for Emerald Ash Borer

 

The Tennessee Department of AgricultureNashville, TN – A quarantine for Emerald Ash Borer, an invasive insect that destroys ash trees has been expanded to include more Tennessee counties. Bradley County, McMinn County, Meigs County and Polk County have been added to the list of areas restricted for the movement of ash trees and ash tree products.

EAB was recently found in McMinn and Polk counties and it is believed that EAB is also likely to be present in Bradley and Meigs counties. This brings the total number of Tennessee counties under a state and federal EAB quarantine to 38.

NASA’s Soil Moisture Active Passive (SMAP) satellite to help Farmers manage Drought conditions

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – About 60 percent of California is experiencing “exceptional drought,” the U.S. Drought Monitor’s most dire classification. The agency issued the same warning to Texas and the southeastern United States in 2012. California’s last two winters have been among the driest since records began in 1879. Without enough water in the soil, seeds can’t sprout roots, leaves can’t perform photosynthesis, and agriculture can’t be sustained.

Currently, there is no ground- or satellite-based global network monitoring soil moisture at a local level. Farmers, scientists and resource managers can place sensors in the ground, but these only provide spot measurements and are rare across some critical agricultural areas in Africa, Asia and Latin America.

For several months, California has been in a state of "exceptional drought." The state's usually verdant Central Valley produces one-sixth of the U.S.'s crops. (White House via Wikimedia Commons)

Austin Peay State University Botanical Garden showcases area’s rare and endangered plants

 

Austin Peay State University - APSUClarksville, TN – A few years ago, three tall, flowering cherry trees grew on the western side of Austin Peay State University’s Sundquist Science Complex. They provided a nice, welcoming entry into the building, but in 2007, Tennessee suffered from a record-setting drought.

Temperatures reached 113 degrees Fahrenheit that summer, and by the fall, the 20-foot tall trees were dead.
