From the coast to the deep sea, changing oxygen levels affect marine life in different ways
Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels change within the course.....»»
Observations explore globular cluster system in the galaxy NGC 4262
Using the Canada-France-Hawaii Telescope (CFHT), Indian astronomers have performed wide and deep field observations of a polar ring galaxy known as NGC 4262. Results of the observational campaign, published April 15 on the pre-print server arXiv, she.....»»
Laser-treated cork absorbs oil for carbon-neutral ocean cleanup
Oil spills are deadly disasters for ocean ecosystems. They can have lasting impacts on fish and marine mammals for decades and wreak havoc on coastal forests, coral reefs, and the surrounding land. Chemical dispersants are often used to break down oi.....»»
Researchers help migrating salmon survive mortality hot-spot
When Kevin Ryan and the other hardworking volunteers at Mossom Creek Hatchery in Port Moody, B.C. release young coho smolts into the ocean, they're never quite certain how many will return as adults......»»
Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds
Analysis of mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation deep water limb in the North Atlantic has weakened. Two decades of continual observations provide a greater understanding of the Earth's cl.....»»
Using deep learning to image the Earth"s planetary boundary layer
Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer (PBL)—the lowest layer of the troposphere—is actually the part that most significantly influences weather nea.....»»
Marine microbial populations: Potential sensors of the global change in the ocean
Animal and plant populations have been extensively studied, which has helped to elucidate ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations, due to the impossibility of isolating, culturi.....»»
Fallout games continue seeing big player jumps after the TV series’ success
Being on deep discount doesn't hurt, either. Enlarge / Seeing power armor in the Fallout series inspired many players to jump back into their own suits (and start stockpiling fusion cores). (credit: Amazon/MGM Studios) L.....»»
Respiratory stress response that stunts temperate fish also affects coral reef fish
Coral reef fish, like the fish in other marine and freshwater ecosystems, are likely to reach smaller maximum sizes and start reproducing earlier with smaller and fewer eggs as climate change continues to warm up the ocean......»»
Plugging the leak on laundry pollution
Joaquim Goes, an ocean biochemist at Columbia Climate School's Lamont-Doherty Earth Observatory, had to look twice when he first saw the tiny strands of fiber floating in a water sample from the Hudson River. An expert in microplastics detection, he.....»»
Anthropocene activities dramatically alter deep underground fluid flux, researchers find
Much of Earth's water is hidden hundreds of meters beneath our feet, among soil particles and deep within rock pores and fractures......»»
NASA"s near space network enables PACE climate mission to "phone home"
The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission has delivered its first operational data back to researchers, a feat made possible in part by innovative, data-storing technology from NASA's Near Space Network, which introduced two key en.....»»
Ocean environment safety of nanocellulose investigated in study of mussels
Cellulose nanofibers represent a promising resource for multiple industrial sectors, but what is their impact on the marine environment? A study published in Environmental Science: Nano recently addressed this issue in a study on marine organisms con.....»»
Saturn"s ocean moon Enceladus could support life—researchers are working out how to detect extraterrestrial cells there
Saturn has 146 confirmed moons—more than any other planet in the solar system—but one called Enceladus stands out. It appears to have the ingredients for life......»»
A clinical decision support system for Earth-independent medical operations
Deep space exploration requires a paradigm shift in astronaut medical support toward Earth-independent medical operations. Currently, astronauts rely on real-time communication with ground-based medical providers. However, as the distance from Earth.....»»
Coral reef microbes point to new way to assess ecosystem health
A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health......»»
Huge database gives insight into salmon patterns at sea
A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The study is published i.....»»
Plastic pollution can kill variety of ocean embryos
High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows......»»
Researchers reveal oceanic black carbon sink effect driven by seawater microdroplets
Pyrogenic carbon is widely produced during the incomplete combustion of biomass and fossil fuels on land. About one-third of pyrogenic carbon is exported to the ocean by rivers, and thereinto, the refractory fraction becomes the source of oceanic bla.....»»
Uranium-immobilizing bacteria in clay rock: Exploring how microorganisms can influence the behavior of radioactive waste
When designing repositories for high-level radioactive waste in deep geological layers, various factors must be carefully considered to ensure their long-term safety. Among other things, natural communities of microorganisms can influence the behavio.....»»
