New study unravels long-standing climate mystery and provides insight into how our planet may change in the future. Scientists claim to have found the “missing link” in the process that leads to an ice age on Earth. Melting icebergs in the Antarctic are the key, say the team from Cardiff […]

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago — and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming — both past and […]

Fishing boats amidst “Arctic sea smoke” near Qingdao, China on January 7th. Arctic sea smoke is a result of frigid air passing over relatively warm water; the phenomenon is rare, even in the Arctic.

Coastal groundwater discharge can sometimes be seen at low tide as rivulets flowing into the ocean, as on this beach on Oahu. A global assessment found groundwater discharge plays a more significant role in ocean chemistry than had been thought. Credit: Jenny Bernier An invisible flow of groundwater seeps into […]

ANIMATION An international research team that included three scientists from the University of Rhode Island’s Graduate School of Oceanography has discovered single-celled microorganisms in a location where they didn’t expect to find them. “Water boils on the (Earth’s) surface at 100 degrees Celsius, and we found organisms living in sediments at […]

Epizoanthus martinsae lives on black corals at depths of almost 400m ATLAS Almost five years of studying the deep Atlantic in unprecedented detail has revealed 12 species new to science. The sea mosses, molluscs and corals had eluded discovery because the sea floor is so unexplored, scientists say. Researchers warn […]

The 60-year-old sub is preparing to take its deepest plunge yet. But in the age of autonomous machines, why are humans exploring the ocean floor at all? COURTESY OF WOODS HOLE OCEANOGRAPHIC INSTITUTION IN EARLY MARCH, a gleaming white submarine called Alvin surfaced off the Atlantic coast of North Carolina after spending the […]

The Pacific Ocean’s currents support a diverse ecosystem, seen here from space with green indicating blooms of photosynthesizing plankton. Warmer currents during the ice age may also have supported early human settlements.
