Phosphates Reveal High pH Ocean Water on Enceladus
Enceladus offers our best opportunity for exploring the chemistry of an ocean on another world. Here, we perform geochemical modeling to show how the distribution of phosphate species found in ice grains from Enceladus's plume provides a very straightforward constraint on the pH of the host solution. The ratio of HPO$_4$/PO$_4$ species serves as a pH indicator. We find evidence of moderately alkaline water (pH 10.1-11.6)--significantly more alkaline than current estimates (~8-9) of the pH of En…

The oceans are overheating—and scientists say a climate tipping point may be here
In 2023, the world’s oceans experienced the most intense and widespread marine heatwaves ever recorded, with some events persisting for over 500 days and covering nearly the entire globe. These searing ocean temperatures are causing mass coral bleaching and threatening fisheries, while also signaling deeper, system-wide climate changes.

It’s a vicious cycle:
Pumping for groundwater is dehydrating our world.
And yet, people take more water from underground due to need, when climate-driven heat and drought are at their worst.

As ocean acidification ramps up, experts call for speedy ocean protection
Ocean health is moving into a danger zone, with rampant human-caused carbon dioxide emissions having already pushed ocean acidification levels beyond safe limits in large swaths of the marine environment, according to a recent study. The new findings underline the urgent need to ramp up protection of the world’s oceans, while simultaneously slashing CO2 emissions, […]

Continents have lost so much water to the ocean since 2002 that they have surpassed ice sheets as the biggest contributor to global sea level rise, a new study reveals.
Almost 70% of this loss is due to unchecked groundwater extraction,
which removes water from deep aquifers and eventually transfers it to the ocean, researchers found.
Together with rising rates of evaporation due to climate change, this has caused rapidly drying "hotspots" to merge into four &quo…

'Like a creeping mold that's spreading across the landscape': Separate dry areas around the world are merging into 'mega-drying' regions at an alarming rate, study finds
Unchecked groundwater extraction and climate change have dried continents significantly over the past 22 years, with 101 countries now losing fresh water to the ocean, research reveals.

Satellite tracking of 12,000 marine animals reveals ocean giants are in trouble
A massive global collaboration has tracked over 12,000 marine animals from whales to turtles to create one of the most detailed movement maps of ocean giants ever assembled. The project, MegaMove, highlights how animal migrations intersect with fishing, shipping, and pollution, revealing alarming gaps in current ocean protections. Even if 30% of the oceans were protected, most critical habitats would still be exposed to threats.

Central American countries most affected by plastic bottle pollution #America

Central American countries most affected by plastic bottle pollution
Most of the plastic bottles and caps that pollute the Pacific coasts of Latin American countries are of local origin, and are mainly produced by the multinational companies The Coca-Cola Company, Aje Group and PepsiCo. The countries most affected by these pollutants are those in Central America, probably due to high consumption of beverages in plastic containers, poor waste management and transport by ocean currents. On the island coasts, bottles of Asian origin are more abundant, probably dump…

North Pacific waters are acidifying more rapidly below the surface, research reveals
Carbon dioxide in the atmosphere enters the ocean at the surface and has been increasing the acidity of Pacific waters since the beginning of the industrial revolution over 200 years ago. A new study, led by University of Hawai'i at Mānoa oceanographers, revealed that the ocean is acidifying even more rapidly below the surface in the open waters of the North Pacific near Hawai'i.
