Growth of Fiber Optic Sensing for Sensitive Pipeline, Concrete and Subsea Cable Applications

By Joseph Shih, Seal-Connect Technical Product Specialist, Greene Tweed  The use of distributed sensing (DS) is on the rise, especially for sensitive oil and gas and pipeline applications, structural health monitoring in concrete structures, and subsea cable infrastructure monitoring for offshore wind energy power sources.  DS enables precise monitoring that can benefit operators seeking to

California Field Campaign Helping Scientists Protect Diverse Ecosystems

With a plane crisscrossing the sky and researchers working on land and sea, the Surface Biology and Geology High-Frequency Time Series campaign (SHIFT) combines the ability of airborne science instruments to gather data over widespread areas with the more concentrated observations scientists conduct in the field to study natural environments. SHIFT is jointly led by

NASA Finds New Way to Monitor Underground Water Loss

Scientists have produced a new method that holds the promise of improving groundwater management critical to both life and agriculture in dry regions. The method sorts out how much underground water loss comes from aquifers confined in clay, which can be drained so dry that they will not recover, and how much comes from soil

International Sea-Level Satellite Takes Over From Predecessor

On March 22, 2022, the newest U.S.-European sea-level satellite, Sentinel-6 Michael Freilich, became the official reference satellite for global sea-level measurements. This means that sea-surface height data collected by other satellites will be compared to the information produced by Sentinel-6 Michael Freilich to ensure their accuracy. Launched from Vandenberg Air Force Base in November 2020,

No Breathing Easy for City Dwellers: Particulates

Air pollution is the fourth-leading risk factor for death around the world. But one type of pollutant is particularly harmful: fine particulate matter (PM2.5). These small, inhalable particles (less than 2.5 micrometers in diameter) result from direct emissions into the air as well as interactions among other pollutants. PM2.5 is the leading cause of death

Quantum Sensor Breakthrough Paves Way for Groundbreaking Map of World Under Earth’s Surface

An object hidden below ground has been located using quantum technology, a long-awaited milestone with profound implications for industry, human knowledge and national security. University of Birmingham researchers from the UK National Quantum Technology Hub in Sensors and Timing reported their achievement in Nature. It is the first in the world for a quantum gravity

West Nile Virus and Mosquito Nuisance Prevention with a UAV

For a nuisance-reduction program after a summer rainfall 2021, GDG was challenged to monitor a several-thousand-hectare region and treat all mosquito breeding sites within it in just five days. As a result, biological larvicide treatment was applied to nearly one thousand hectares of areas producing mosquito larvae by GDG’s drone division in 2021.  “Once a

Volcano-Observing Drone Flights Open Door to Routine Hazard Monitoring

The ability to provide a “volcano forecast” could help reduce the significant health, safety and even economic impacts of eruptions; they regularly disrupt aviation and the global supply chain we depend on. Last fall, circling the summit of an active volcano, a small aircraft moved us toward a future where remote but hazardous volcanoes are

2021 Tied for 6th Warmest Year in Continued Trend, NASA Analysis Shows

Earth’s global average surface temperature in 2021 tied with 2018 as the sixth-warmest on record, according to independent analyses done by NASA and the National Oceanic and Atmospheric Administration (NOAA). Continuing the planet’s long-term warming trend, global temperatures in 2021 were 1.5 degrees Fahrenheit (0.85 degrees Celsius) above the average for NASA’s baseline period, according

NASA-NOAA Tech Will Aid Marine Oil Spill Response

NASA and National Oceanic and Atmospheric Administration (NOAA) scientists are teaming up to test remote-sensing technology for use in oil-spill response.  Just off the coast of Santa Barbara, Calif., thousands of gallons of oil seep through cracks in the seafloor and rise to the surface each day. But this isn’t a disaster zone: It’s one
