Hedging strategy for coral restoration balances diversity, ecosystem benefits      (via sciencedaily.com)     Original source 

An international team of researchers developed an innovative new strategy for choosing a set of key coral species that will best maintain ecosystem functions critical for reef health. Their hedging approach provides a simple framework for aiding restoration practitioners in selecting target species for their projects, depending on spatial scale and resources.

Water storage capacity in oceanic crust slabs increases with age, researchers find      (via sciencedaily.com)     Original source 

An international research team has discovered that a subduction zone's age affects the ability for it to recycle water between the Earth's surface and its inner layers. The more mature the subduction zone, the bigger the water storage capacity.

Expanding large-scale agriculture is escalating flooding in the largest South American breadbasket      (via sciencedaily.com)     Original source 

Driven by soaring international demand, extensive areas of grasslands, and forests across South American plains have rapidly been converted to the production of annual crops, such as soybean and maize. This agricultural expansion has been taking place at a staggering rate of 2.1 million hectares a year. A new study shows how these shifts to annual crop agriculture, which relies on rainfall rather than irrigation, is also rapidly disrupting the water table across the large flat regions of the Pampas and Chaco plains and contributing to significantly increased risks of surface flooding.

Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes      (via sciencedaily.com)     Original source 

Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire. A new study suggests a notable amount of such subducted carbon returns to the atmosphere rather than traveling deep into Earth's mantle.

Geologists are using artificial intelligence to predict landslides      (via sciencedaily.com)     Original source 

Many factors influence where a landslide will occur, including the shape of the terrain, its slope and drainage areas, the material properties of soil and bedrock, and environmental conditions like climate, rainfall, hydrology and ground motion resulting from earthquakes. Geologists have developed a new technique that uses artificial intelligence to better predict where and why landslides may occur could bolster efforts to protect lives and property in some of the world's most disaster-prone areas. The new method improves the accuracy and interpretability of AI-based machine-learning techniques, requires far less computing power and is more broadly applicable than traditional predictive models.

What are the characteristics of foreshocks for large earthquakes?      (via sciencedaily.com)     Original source 

Seismologists agree that foreshocks are the most widely identified signal of an upcoming mainshock earthquake. But do these foreshock sequences have distinctive characteristics that separate them from aftershock sequences, and could these characteristics be used to help forecast mainshocks?

Multiscale rupture growth driven by a complex fault network during the 2023 Türkiye and Syria earthquake doublet      (via sciencedaily.com)     Original source 

Researchers analyzed the source processes of the twin earthquakes that caused extensive damage in Türkiye and Syria on February 6, 2023. The results revealed that a complex fault network with bends, steps, and branches controlled the propagation speed and direction of the rupture, leading to hierarchical small to large rupture growth.

Worse than diesel and gasoline? Bioenergy as bad as fossils if there is no pricing of CO2 emissions from land-use change, experts argue      (via sciencedaily.com)     Original source 

Demand for modern biofuels is expected to grow substantially in order to mitigate climate emissions. However, they are far from being a climate neutral alternative to gasoline and diesel. A new study shows that under current land-use regulations, CO2 emission factors for biofuels might even exceed those for fossil diesel combustion due to large-scale land clearing related to growing biomass. Before bioenergy can effectively contribute to achieving carbon neutrality, international agreements need to ensure the effective protection of forests and other natural lands by introducing carbon pricing, the expert team argues.

How coral reefs can survive climate change      (via sciencedaily.com)     Original source 

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
