Researchers discovered that a dissolved form of manganese can keep toxic hydrogen sulfide zones in check by reacting with oxygen and hydrogen sulfide. This finding alters the understanding of manganese aqueous geochemistry and has implications for waterways like the Black Sea and Chesapeake Bay.
Scientists uncover evidence of massive soil erosion as primary cause of end-Permian extinction, which wiped out over two-thirds of reptile and amphibian families. The research reveals a unique set of molecules found in rocks from Italy provided crucial insights into the event.
Researchers reveal that underground water played a crucial role in cooling the planet, with strontium levels 10 times higher than river waters. The study changes perception on ocean chemistry, highlighting the importance of groundwater in global climate models.
Researchers have discovered a 4.4-billion-year-old zircon crystal that suggests the early Earth had a low-temperature environment with water and conditions suitable for life. The findings contradict conventional wisdom, which predicted a magma ocean, and may indicate the Earth cooled faster than thought.
Scientists analyze melt inclusions in Hawaiian crystals, finding highly unusual trace-element contents that match a specific rock type. The study confirms a giant recycling process where ancient oceanic crust is melted and re-formed in the Earth's mantle.
Researchers from Monterey Bay Aquarium Research Institute and Stanford University conducted experiments on liquid CO2 disposal in the deep ocean. The results show that liquid CO2 can react with seawater to form clathrate hydrate, expanding in volume and causing it to rise towards the surface.
A dense brownish haze layer extended from the ocean surface to 1-3 km altitude, impacting climate processes over the northern Indian Ocean. The haze reduced solar radiation absorbed by the ocean surface by as much as 10%, altering weather and climate dynamics.
The Florida Regional Competition of the National Ocean Sciences Bowl will be held in Fort Pierce, with 25 teams competing for scholarships and awards. The competition aims to broaden awareness and understanding of ocean research among high school students.
