Latest Sea ice Stories
NASA's first dedicated oceanographic field campaign goes to sea June 15 to take an up-close look at how changing conditions in the Arctic are affecting the ocean's chemistry and ecosystems that play a critical role in global climate change.
Less ice covers the Arctic today than at any time in recent geologic history.
Melting sea ice has been shown to be a major cause of warming in the Arctic.
Scientists have discovered that changes in the amount of ice floating in the polar oceans are causing sea levels to rise.
Close to 50 years of data show the Devon Island ice cap, one of the largest ice masses in the Canadian High Arctic, is thinning and shrinking.
The US National Snow and Ice Data Center reports that the extent of sea ice over the Arctic Ocean grew until the last day of March, which is the latest the annual melting season has begun in 31 years of satellite records.
The main cause of a rapid global cooling period, known as the Big Freeze or Younger Dryas - which occurred nearly 13,000 years ago - has been identified thanks to the help of an academic at the University of Sheffield.
As ESAâ€™s Mission Scientist for CryoSat, Mark Drinkwaterâ€™s role in supporting the preparation of the mission has been to ensure that the satellite and data processing systems are compatible with achieving the missionâ€™s objectives of deriving accurate measurements of ice-thickness change.
A mammoth iceberg that struck a glacier off Antarctica, dislodged a newer chunk of ice that could affect ocean currents and also lower the levels of oxygen in the worldâ€™s oceans.
In 2007, the Arctic lost a massive amount of thick, multiyear sea ice, contributing to that year's record-low extent of Arctic sea ice.
The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...
