Mon, 27 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) To time how long it takes a pulse of laser light to travel from space to Earth and back, you need a really good stopwatch -- one that can measure within a fraction of a billionth of a second.
Mon, 27 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) Tropical Cyclone Caleb is weakening in the Southern Indian Ocean and NASA's Aqua satellite caught one of the last bursts of strength as it passed overhead.
Mon, 27 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) NASA's Aqua satellite passed over the storm early on March 27, 2017 as Tropical Cyclone Debbie had intensified into a powerful hurricane already affecting the coast of eastern Queensland, Australia.
Sun, 26 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) The tropical low pressure area previously known as System 91P has developed into a tropical cyclone named Debbie in the Southern Pacific Ocean and threatens eastern Queensland, Australia. NASA's Aqua satellite provided an infrared look at the storm that revealed powerful thunderstorms quickly developed around the center. Debbie has already triggered warnings in Queensland.
Sat, 25 Mar 2017 00:00:00 EDT(CAGE - Center for Arctic Gas Hydrate, Climate and Environment) The Norwegian Sea acted as CO2 source in the past. It pumped the greenhouse gas into the atmosphere instead of absorbing it, as it does today.
Fri, 24 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) The area of tropical low pressure designated System 91P appears to be organizing in NASA satellite imagery on March 24. Visible imagery from NASA-NOAA's Suomi NPP satellite revealed that the tropical low is consolidating and strengthening in the Coral Sea, South Pacific Ocean.
Fri, 24 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) Tropical cyclone Caleb formed on March 23 in the South Indian Ocean southwest of the Indonesian Island of Sumatra. The GPM core observatory satellite had a fairly good view of the newly formed tropical cyclone when it flew overhead and analyzed its rainfall and found the heaviest precipitation was affected by westerly winds.
Fri, 24 Mar 2017 00:00:00 EDT(University of Texas at Arlington) A biologist from the University of Texas at Arlington is leading a new study aimed at quantifying how susceptible coral species are to disease by examining their immunity through a series of novel experiments and approaches.
Thu, 23 Mar 2017 00:00:00 EDT(Worcester Polytechnic Institute) Tests of a novel technology that can accelerate the combustion of crude oil floating on water demonstrated its potential to become an effective tool for minimizing the environmental impact of oil spills. The Flame Refluxer, developed by fire protection engineering researchers at Worcester Polytechnic Institute with funding from the Bureau of Safety and Environmental Enforcement, could make it possible to burn off spilled oil quickly while producing relatively low levels of air pollutants.
Thu, 23 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) The Global Precipitation Measurement mission or GPM constellation of satellites provide data on precipitation rates and totals. Recently the GPM core observatory measured the heavy rainfall that caused extensive flooding and loss of life in Peru.
Thu, 23 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) Shortly after Tropical Cyclone Caleb formed east of Cocos Island, NASA-NOAA's Suomi NPP satellite and NASA's Aqua satellite passed overhead gathering visible and infrared data on the twelfth tropical cyclone of the Southern Indian Ocean season.
Thu, 23 Mar 2017 00:00:00 EDT(Florida Atlantic University) FAU's Southeast National Marine Renewable Energy Center (SNMREC), a US Department of Energy designated center, is focused on advancing science and technology to recover energy from the oceans' renewable resources with special emphasis on those resources available to the southeastern US, initially focusing on ocean currents and thermal resources.
Thu, 23 Mar 2017 00:00:00 EDT(Woods Hole Oceanographic Institution) In the South China Sea, a 2°C rise in the sea surface temperature in June 2015 was amplified to produce a 6°C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study published in Scientific Reports this week.
Wed, 22 Mar 2017 00:00:00 EDT(National Socio-Environmental Synthesis Center) Marine protected areas (MPAs) are an increasingly popular strategy for protecting marine biodiversity, but a new global study demonstrates that widespread lack of personnel and funds are preventing MPAs from reaching their full potential. Only 9 percent of MPAs reported having adequate staff.The findings are published in the journal Nature on March 22.
Mon, 20 Mar 2017 00:00:00 EDT(NIOZ Royal Netherlands Institute for Sea Research) Dikes could be lower if they are protected against the waves by grassy marshes. But the protective salt marsh grass is struggling, not only due to increasingly stronger waves, but also to the superfood diet of ragworms. These sophisticated gardeners turn inedible, tough grass seeds into succulent, nutritious sprouts in their burrows. These cultivation techniques prevent many seeds from growing into salt marsh vegetation, thus undermining the use of salt marshes for 'natural' coastal protection.
Thu, 16 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) Ex-tropical cyclone 11S was still generating some heavy rainfall, despite losing its tropical status and becoming a sub-tropical storm when the GPM core satellite passed overhead. The Global Precipitation Measurement mission or GPM core satellite passed over the remnant low pressure area and analyzed the rain the system was generating.
Thu, 16 Mar 2017 00:00:00 EDT(University of California - Santa Barbara) Marine biologists quantify the carbon consumption of bacterioplankton to better understand the ocean carbon cycle.
Thu, 16 Mar 2017 00:00:00 EDT(Carnegie Institution for Science) Rock samples from northeastern Canada retain chemical signals that help explain what Earth's crust was like more than 4 billion years ago, reveals new work from Carnegie's Richard Carlson and Jonathan O'Neil of the University of Ottawa.
Wed, 15 Mar 2017 00:00:00 EDT(University of Washington) A properly-managed subsistence harvest of polar bears can continue under climate change, according to analysis that combines sea-ice forecasts with a polar bear population model.
Wed, 15 Mar 2017 00:00:00 EDT(NASA/Goddard Space Flight Center) Once a tropical storm, now a sub-tropical storm, the remnants of the tropical low pressure area formerly known as 11S was spotted by NASA's Aqua satellite, still spinning in the Southern Indian Ocean.
Wed, 15 Mar 2017 00:00:00 EDT(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) Polar cod fulfill a key role in the Arctic food web, as they are a major source of food for seals, whales and seabirds alike. But the polar cod themselves might soon be the hungry ones.
Wed, 15 Mar 2017 00:00:00 EDT(ETH Zurich) Microscopic marine plankton are not helplessly adrift in the ocean. They can perceive cues that indicate turbulence, rapidly respond to regulate their behavior and actively adapt. ETH researchers have demonstrated for the first time how they do this .
Tue, 14 Mar 2017 00:00:00 EDT(California Institute of Technology) A new study suggests that efficient nutrient consumption by plankton in the Southern Ocean drove carbon sequestration in the deep ocean during the ice ages.
Tue, 14 Mar 2017 00:00:00 EDT(University of Wyoming) Barbara John and her husband, Michael Cheadle, both UW professors of geology and geophysics, recently co-led a research expedition aboard the US Research Vessel Atlantis. With the aid of two small submarines tasked with exploring and sampling the sea floor, the group located five new hydrothermal vents, as well as two others that were last seen 23 years ago, at Pito Seamount in the Pacific Ocean.
Tue, 14 Mar 2017 00:00:00 EDT(GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre) GRACE began with a radical idea. Principal investigator Byron Tapley (University of Texas Center for Space Research) said, 'The completely new idea about GRACE was the perception that measuring and tracking mass gives you a way to probe the Earth system.' Measuring changes in mass has been a key to discovering how water and the solid Earth are changing deep underground in places humans can't go and can't see.
