NASA prepares for future Satellite by studying Coral Reefs of Hawaii

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA pulled off a scientific double play in Hawaii this winter, using the same instruments and aircraft to study both volcanoes and coral reefs. Besides helping scientists understand these two unique environments better, the data will be used to evaluate the possibility of preparing a potential future NASA satellite that would monitor ecosystem changes and natural hazards.

The advantages of studying active volcanoes from the air rather than the ground are obvious. Coral reefs may not offer the same risks in a close encounter that volcanoes do, but there’s another good reason to study them by remote sensing: they’re dotted across thousands of square miles of the globe.

NASA Climate Models show that El Niño event could happen later this year

 

Written by Alan Buis

NASA - National Aeronautics and Space AdministrationPasadena, CA – Some climate models are suggesting that El Niño may return later this year, but for now, the Pacific Ocean lingers in a neutral “La Nada” state, according to climatologist Bill Patzert of NASA’s Jet Propulsion Laboratory, Pasadena, California.

The latest map of sea level height data from the U.S./European Jason-3 satellite mission shows most of the ocean at neutral heights (green), except for a bulge of high sea level (red) centered along 20 degrees north latitude in the central and eastern Northern Hemisphere tropics, around Hawaii. This high sea level is caused by warm water.

Data collected Feb. 28 - March 12, 2017, by the U.S./European Jason-3 satellite show near-normal ocean surface heights in green, warmer areas in red and colder areas in blue. Ocean surface height is related in part to its temperature, and thus is an indicator of how much heat is stored in the upper ocean. (NASA/JPL-Caltech)

AAA reports Gas Prices Make Slow 10 Day Decline

 

AAATampa, FL – After remaining relatively flat, the national average price for regular unleaded gasoline has now fallen for 10 straight days to today’s average of $2.30 per gallon.

Today’s national average is one cent less than one week ago and two cents more than one month ago. Compared to this same date last year, consumers are paying 37 cents more per gallon at the pump.

Gas Prices Remain Steady Despite Increased U.S. Production reports AAA

 

AAATampa, FL – Oil prices slipped fractions of a penny over the weekend, reaching today’s national average price for regular unleaded gasoline of $2.31 per gallon. Today’s price is still two cents more than one week ago, four cents more compared to one month ago and 50 cents more per gallon year-over-year.

Retail prices continue to fluctuate but have remained between $2.28-2.32 for more than a month as reports of increased U.S. production continues to counter OPEC rebalancing efforts.

AAA reports Average Gas Prices Remain Steady Despite Low Demand

 

AAATampa, FL – National gas prices have increased fractions of a penny to reach today’s average price for regular unleaded gasoline, which is $2.28 per gallon. Today’s average is the same as one week ago, five cents less compared to one month ago and 56 cents more than the same date last year.

Prices continue to remain flat due to lower driving demand and an oversupplied market as a result of increased U.S. production. As refinery maintenance season begins and driving demand increases, we could expect to see some of the gasoline supply in the U.S. soaked up.

NASA reports Vortex Coronagraph takes it’s first Planetary System Images

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new device on the W.M. Keck Observatory in Hawaii has delivered its first images, showing a ring of planet-forming dust around a star, and separately, a cool, star-like body, called a brown dwarf, lying near its companion star.

The device, called a vortex coronagraph, was recently installed inside NIRC2 (Near Infrared Camera 2), the workhorse infrared imaging camera at Keck. It has the potential to image planetary systems and brown dwarfs closer to their host stars than any other instrument in the world.

AAA reports National Gas Price Average Drops for 21 Consecutive Days

 

AAATampa, FL – Continual growth in the number of U.S. oil rigs and the increased drilling it implies are raising expectations for a climb in domestic oil production. Additionally, increased U.S. crude oil production coupled with lower driving demand has kept downward pressure on the national average price at the pump, which has fallen for 21 consecutive days.

Today’s national average price for regular unleaded gasoline is $2.27 per gallon, down four cents versus one week ago, five cents less than one month ago, but 47 cents more per gallon year-over-year.

AAA reports Increased U.S. Oil Production Pushes Pump Prices Lower

 

AAATampa, FL – The national average price of gas continues to decline as U.S. oil production increases. Today’s average price of $2.31 per gallon represents a decrease of three cents per gallon on the week, four cents per gallon on the month, and prices have moved lower for 14 of the past 15 days.

Despite this recent trend lower, retail averages are up by 46 cents per gallon as compared to one year ago.

AAA reports Pump Prices have Dropped for Eight Consecutive Days

 

AAATampa, FL – Gas prices have fallen for eight consecutive days, reaching today’s national average price of $2.34 per gallon. The price of retail gasoline has retreated since last week with today’s average three cents less per gallon than one week ago, but ten cents more than one month ago and 43 cents more per gallon year-over-year.

The slight decrease in retail prices can be attributed to less demand and adequate supply, but this downward dip may only be temporary as the market awaits OPEC’s December monthly output report which is due out later this week.
