Published Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat
(via sciencedaily.com) Original source A new Antarctic ice sheet modeling study suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster.
Published 'Robin Hood' approach for tracking biodiversity
(via sciencedaily.com) Original source Researchers have developed a framework that can help scientists understand trends in biodiversity by using data from well-characterized species to provide insights on data-deficient species. The framework provides a how-to guide for researchers and practitioners to implement.
Published Mystery of volcanic tsunami solved after 373 years
(via sciencedaily.com) Original source The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo's underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only be described by a combination of a landslide followed by an explosive eruption.
Published Marine protected areas and climate change
(via sciencedaily.com) Original source New research offers a way to build climate resilience into the designs of ocean and coastal areas intended to protect marine species. The researchers recommend establishing numerous marine protected areas across political borders, starting with the Southern California Bight.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published UK air pollution regulations will reduce deaths, but do little to protect ecosystems
(via sciencedaily.com) Original source Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com) Original source A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
Published Light, freshwater sticks to Greenland's east coast
(via sciencedaily.com) Original source Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island. In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.
Published Increased West Antarctic Ice Sheet melting 'unavoidable'
(via sciencedaily.com) Original source The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to new research. A substantial acceleration in ice melting likely cannot now be avoided, which implies that Antarctica's contribution to sea level rise could increase rapidly over the coming decades.
Published Soft, living materials made with algae glow under stress
(via sciencedaily.com) Original source Researchers have developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego's beaches.
Published El Niño's changing patterns: Human influence on natural variability
(via sciencedaily.com) Original source Two recent scientific studies provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño responds to natural factors over extended periods, while highlighting the increasing role of human activities in shaping this climatic phenomenon in the modern era.
Published Unearthing the ecological impacts of cicada emergences on North American forests
(via sciencedaily.com) Original source New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com) Original source The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
(via sciencedaily.com) Original source Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.
Published Ice sheet surface melt is accelerating in Greenland and slowing in Antarctica
(via sciencedaily.com) Original source Surface ice in Greenland has been melting at an increasing rate in recent decades, while the trend in Antarctica has moved in the opposite direction, according to researchers.
Published Marine bacteria take a bite at plastic pollution
(via sciencedaily.com) Original source A bacterium found in the sea can degrade a plastic that otherwise resists microbial breakdown in marine environments.
Published New study confirms presence of flesh-eating and illness-causing bacteria in Florida's coastal waters following Hurricane Ian
(via sciencedaily.com) Original source When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.
Published Climate change coping mechanism discovered in humble algae
(via sciencedaily.com) Original source One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.
