Sea Ice To Ocean Currents, Antarctica Is Undergoing Abrupt Changes
Melting sea ice allows oceans to warm more rapidly, which melts more sea ice. Once triggered, they can be difficult or even impossible to reverse on timescales meaningful to humans.

Atlantic Hurricane Season Sets Peak Record As Storm Erin Threatens US Coast
Hurricane Erin's massive footprint battered Caribbean islands with heavy gusts and downpours on Monday, as it threatened rip currents and flooding along the US East Coast later this week, even without a predicted landfall.

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...

Global Antarctic Research Declines Amid Growing Climate Crisis
Ice loss in Antarctica and its impact on the planet - sea level rise, changes to ocean currents and disturbance of wildlife and food webs - has been in the news a lot lately.

NASA’s SWOT Satellite Reveals Big Impact of Small Ocean Currents and Waves in n Marine Ecosystems
NASA’s SWOT satellite, in collaboration with CNES, reveals how submesoscale ocean features just a mile wide drive vital vertical circulation. These small currents transport heat, carbon, and nutrients, profoundly influencing marine ecosystems and climate systems. The mission’s high-resolution data is reshaping how scientists model ocean-atmosph...

Antarctic Ice Melt Weakens Strongest Ocean Current, Disrupting Global Circulation
The Antarctic Circumpolar Current, the planet’s most powerful ocean circulation system, could slow by 20 percent by 2050 due to melting Antarctic ice. Researchers suggest that the influx of fresh, cold water is disrupting convection, altering global ocean density. A weaker current may allow warm water to reach Antarctica, accelerating ice loss an...

On International Women's Day, Indian Navy Salutes 2 Women Officers Circumnavigating Globe
On the occasion of International Women's Day 2025, the Indian Navy shared a video showcasing the journey of two women officers who are currently sailing in the South Atlantic Ocean aboard the Indian Naval Sailing Vessel (INSV) Tarini.

Earth's Strongest Ocean Current Is Slowing Down And It Could Have Devastating Consequences
The ocean current might slow down by around 20 per cent by 2050 in the "high carbon emissions scenario".

Melting Ice Could Slow World's Strongest Ocean Current: Study
The world's strongest ocean current could slow as melting Antarctic ice sheets flood it with fresh water, according to research published on Monday that warned of "severe" climate consequences.
-
Greenland's Ice Sheet Approaches Dangerous Tipping Point Amid Rapid Melting
Greenland’s massive ice sheet is losing ice at an accelerating rate, with scientists warning that a global temperature rise of just 2°C could trigger irreversible collapse. The loss of 230 gigatons of ice per year is the estimated threshold for this tipping point. If melting continues at current rates, sea levels could rise by approximately 7 me...

Denmark Strait Cataract: World's Largest Underwater Waterfall Discovered
The Denmark Strait cataract, the world’s largest underwater waterfall, is located between Iceland and Greenland. Plunging 11,500 feet from top to bottom, it plays a key role in the global ocean circulation system. The waterfall forms part of the thermohaline circulation, which helps regulate the Earth's climate. Despite its immense size, it remai...

World's Largest Iceberg A23a Breaks Free, Drifts In The Southern Ocean
As A23a continues on its journey, it is anticipated to follow the Antarctic Circumpolar Current into the Southern Ocean.

Indian Ocean Study Reveals Bay of Bengal Defies Ekman’s Wind-Driven Current Theory
A study published in Science Advances has discovered that ocean currents in the Bay of Bengal deviate leftward, contrary to Ekman’s century-old theory. This anomaly, revealed through multi-year buoy data, suggests local factors influence wind-driven surface currents. Researchers highlight implications for climate models and propose a satellite sy...

NASA Europa Clipper Advances Toward Jupiter’s Moon, Instruments Successfully Deployed
NASA’s Europa Clipper spacecraft, launched in October 2024, is journeying toward Jupiter’s moon Europa to study its icy surface and hidden ocean. Currently over 13 million miles from Earth, the spacecraft has successfully deployed its solar arrays, magnetometer boom, and radar antennas. It will use a gravity assist from Mars in March 2025 to ad...

Irminger Sea’s Crucial Role in Atlantic Ocean Current Collapse Identified
A new study highlights the vital role of the Irminger Sea in the Atlantic Meridional Overturning Circulation (AMOC). Increasing meltwater from the Arctic is weakening this critical ocean current, which regulates global climate. The research suggests that disruptions in the Irminger Sea could cause widespread climate shifts, including cooling in the...
