The ocean surface wind mediates exchanges between the and atmosphere. These air–sea exchange processes are critical for understanding predicting atmosphere, ocean, wave phenomena on many time space scales. A cross-calibrated multiplatform (CCMP) long-term data record of satellite winds is available from 1987 to 2008 with planned extensions through 2012. variational analysis method (VAM) used combine derived conventional in situ sources multiple satellites into a consistent nearglobal at...
The devastating environmental impacts of the Exxon Valdez spill in 1989 and its media notoriety made it a frequent comparison to BP Deepwater Horizon popular press 2010, even though nature two spills environments impacted were vastly different. Fortunately, unlike higher organisms that are adversely by oil spills, microorganisms able consume petroleum hydrocarbons. These degrading indigenous played significant role reducing overall impact both spills.
The Atmospheric Infrared Sounder (AIRS) and its two companion microwave sounders, AMSU HSB were launched into polar orbit onboard the NASA Aqua Satellite in May 2002. required sounding system to provide high-quality research data for climate studies meet NOAA's requirements improving operational weather forecasting. NOAA requirement translated global retrieval of temperature humidity profiles with accuracies approaching those radiosondes. AIRS also provides new measurements several...
Experiments were performed to evaluate the effectiveness of two different methodological approaches for recovering DNA from soil and sediment bacterial communities: cell extraction followed by lysis recovery (cell method) versus direct alkaline recover (direct method). Efficiency each method was determined spectrophotometric absorbance using a tritiated thymidine tracer. With both procedures, use polyvinylpolypyrrolidone important removal humic compounds improve purity recovered DNA; without...
Abstract Bioremediation has become a major method employed in restoration of oil‐polluted environments that makes use natural microbial biodegradative activities. petroleum pollutants overcomes the factors limiting rates hydrocarbon biodegradation. Often this involves using enzymatic capabilities indigenous hydrocarbon‐degrading populations and modifying environmental factors, particularly concentrations molecular oxygen, fixed forms nitrogen, phosphate to achieve enhanced Biodegradation...
Crude oil and petroleum products are widespread water soil pollutants resulting from marine terrestrial spillages.
Polymerase chain reaction (PCR) amplification and gene probe detection of regions two genes, lacZ lamB, were tested for their abilities to detect coliform bacteria. Amplification a segment the coding region Escherichia coli by using PCR primer annealing temperature 50 degrees C detected E. other bacteria (including Shigella spp.) but not Salmonella spp. noncoliform lamB selectively radiolabeled probes as little 1 10 fg genomic DNA few 5 viable cells in 100 ml water. provides basis method...
Abstract The Cyclone Global Navigation Satellite System (CYGNSS) is a new NASA earth science mission scheduled to be launched in 2016 that focuses on tropical cyclones (TCs) and convection. mission’s two primary objectives are the measurement of ocean surface wind speed with sufficient temporal resolution resolve short-time-scale processes such as rapid intensification phase TC development ability measurements penetrate through extremely high precipitation rates typically encountered inner...
The three-dimensional global wind field is the most important remaining measurement needed to accurately assess dynamics of atmosphere. Wind information in tropics, high latitudes, and stratosphere particularly deficient. Furthermore, only a small fraction atmosphere sampled terms profiles. This limits our ability optimally specify initial conditions for numerical weather prediction (NWP) models understanding several key climate change issues. Because its extensive heritage (since 1968)...

A method was developed for the detection of fecal coliform bacterium Escherichia coli, using polymerase chain reaction and gene probes, based on amplifying regions uid that code beta-glucuronidase, expression which forms basis by commercially available Colilert method. Amplification probe four different specifically detected E. coli Shigella species, including beta-glucuronidase-negative strains coli; no amplification observed other nonenteric bacteria.
