Cleveland Volcano, Aleutian Islands eruption in 2006. Volcanism is one of the main carbon dioxide sources in the long-term carbon cycle balanced by weathering sinks, which, among others, represent important processes included in Komar and Zeebe’s model.

Stanford researcher Ryan Searcy collects water samples from a tide pool at the Fitzgerald Marine Reserve, in Moss Beach, California. Credit: Meghan Shea Using water samples and environmental data gathered over 48 hours or less, Stanford engineers develop a new predictive technique for forecasting coastal water quality, a critical step […]

Full moon in Tromsø, Norway. Credit: Maja Sojtaric High tides may even counter the potential threat of submarine methane release from the warming Arctic. It may not be very well known, but the Arctic Ocean leaks enormous amounts of the potent greenhouse gas methane. These leaks have been ongoing for […]

Bhattacharya How to Identify Heat-Stressed Corals Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection […]

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 […]

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 […]
