Seawater trapped in ancient rocks opens a window into past ocean chemistry

By using advanced microscopes and imaging technology to study tiny pockets of liquid trapped in ancient minerals, scientists have gained new insights into how seawaters have changed over time, and how they might do so in the future. The research center… Continue reading Seawater trapped in ancient rocks opens a window into past ocean chemistry

Tiger sharks with cameras map out the world’s largest seagrass system

Tiger sharks have a strong symbiotic relationship with seagrass ecosystems, playing the role of apex predator to prevent overgrazing by other species while at the same time patrolling the underwater meadows for sustenance. Scientists studying these spe… Continue reading Tiger sharks with cameras map out the world’s largest seagrass system

Seafloor rover vacuums up valuable metals with smaller footprint

The seafloor is rich in valuable metals, but gathering them is disruptive to the environment. An international project has now tested a system called Apollo 2, which can vacuum up metal nodules without kicking up sediment.Continue ReadingCategory: Tech… Continue reading Seafloor rover vacuums up valuable metals with smaller footprint

Cell-boosting chemical allows deep-sea fish to live under pressure

Ever wonder how deep-sea fish and other animals are able to survive in an environment where the water pressure would kill us humans? According to a recent study, the secret lies in a chemical that occurs naturally in their cells.Continue ReadingCategor… Continue reading Cell-boosting chemical allows deep-sea fish to live under pressure

Japan tests deep-ocean current turbines in search of new renewables

Renewable energy potential is not distributed evenly. Japan, for example, has sub-par solar potential and nowhere near the wind potential of Western Europe or the United States. It’s also currently ranked fifth in the world for electricity consumption,… Continue reading Japan tests deep-ocean current turbines in search of new renewables

New map reveals deepest spot in Southern Ocean around Antarctica

An international team of scientists and cartographers has released the most detailed map ever of the seafloor of the Southern Ocean surrounding Antarctica. It covers 48 million km² (19 million miles²) and includes the deepest spot yet found in the regi… Continue reading New map reveals deepest spot in Southern Ocean around Antarctica

Mayflower autonomous ship successfully crosses the Atlantic

Following a number of technical setbacks, the Mayflower autonomous research vessel has successfully crossed the Atlantic Ocean, clocking up 3,500 miles (5,600 km) and arriving in Halifax, Nova Scotia, on June 5.Continue ReadingCategory: Marine, Transpo… Continue reading Mayflower autonomous ship successfully crosses the Atlantic
