A glacier front meets the sea in Antarctica. The ice sheet holds enough water to raise global sea level by about 190 feet (58 meters). Qiyue Sun

Antarctica’s ice loss is locked in, and extra snowfall won’t save it – that’s bad news for low‑lying coastal areas elsewhere

The Antarctic ice sheet’s future depends how a chain of events plays out. A new study finds the evidence points in one direction.
The Global Ocean Observing System is facing funding pressures and data gaps as a result which leave the world blind. IOW M Naumann

Ocean monitoring is in trouble: without the US, it’s up to Europe and Asia to avoid losing sight of the world’s deep‑sea ecosystems

Defunding marine monitoring networks could jeopardise efforts to avoid losing track of the world’s oceans and their precious ecosystems, which drive the blue economy.
A consequence of dredging deep channels is that water also enters more easily with tides and storm surge. Google Earth

Coastal cities have a hidden vulnerability to storm‑surge and tidal flooding − entirely caused by humans

Some cities are building huge gates and barriers to counter the flood risk from estuary urbanization. But putting nature to work in a big way might be more effective.
Researchers are increasingly using small, autonomous underwater robots to collect data in the world’s oceans. NOAA Teacher at Sea Program,NOAA Ship PISCES

Titan submersible disaster underscores dangers of deep‑sea exploration – an engineer explains why most ocean science is conducted with crewless submarines

Dramatic improvements in computing, sensors and submersible engineering are making it possible for researchers to ramp up data collection from the oceans while also keeping people out of harm’s way.

Scientists envision an ‘internet of the ocean,’ with sensors and autonomous vehicles that can explore the deep sea and monitor its vital signs

The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
For centuries, sailors have told tales of milky seas – huge swaths of ocean glowing on dark nights, seen in blue in this false–color satellite image. Steven D. Miller/NOAA

Scientists are using new satellite tech to find glow‑in‑the‑dark milky seas of maritime lore

When conditions are just right in some parts of the Indian Ocean, a type of bacteria will multiply and start to glow. Satellites are helping scientists study these milky seas for the first time.
