🌊 Ocean fronts are boundaries where different water masses collide. They cover about 1/3 of the global ocean but account for nearly 3/4 of total ocean CO2 uptake, absorbing about 1.8 billion tonnes of carbon each year.

🌊 "Ice shelves act as buttresses for Antarctica’s 30 million cubic kilometres of ice ... The Ross Ice Shelf is the largest, among the coldest and most southerly, and perhaps the most sheltered from a warming ocean."

Beneath Antarctica’s largest ice shelf, a hidden ocean is revealing its secrets
A four-year record from the heart of the Ross Ice Shelf shows how subtle changes could shape future sea level rise, ocean ecosystems – and even our weather.

Some methods being tried to counter climate change shift the ocean’s biology or chemistry. Others would deflect solar radiation. All have consequences for marine life.
