Our knowledge of the depth and shape of the Arctic Ocean floor – its bathymetry – is insufficient. Owing to year-round sea-ice coverage and the cost of research in this remote region, much of ...

For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ...

Ice and snow reflect sunlight, keeping the Arctic cool, while large dark areas of open ocean absorb abundant solar energy, which triggers more ice melt and delays the autumn refreeze.

In February 2025, Seabed 2030 celebrated another 1.4 million square kilometers of seabed map on the International Bathymetric ...

Much of the focus was on the Arctic Ocean, where bathymetric and geologic surveys by federal agencies produced the first detailed maps of a complex seafloor with a series of canyons, ridges and ...

The first ice-free days of the Arctic Ocean could occur as soon as the 2020s or 2030s — as many as 10 years earlier than previous projections.

LEONID POLYAK, MARTIN JAKOBSSON, Quaternary Sedimentation in the Arctic Ocean, Oceanography, Vol. 24, No. 3, The Changing Arctic Ocean: SPECIAL ISSUE ON THE INTERNATIONAL POLAR YEAR (2007–2009) ...

The Arctic Ocean has always been a region that’s fascinated University of Delaware doctoral student Tianyu Zhou. While most of humanity lives in the world’s temperate zone, the polar ocean seems like ...

As Earth warms, the Arctic Ocean’s ability to absorb carbon dioxide from the atmosphere is waning due to melting permafrost and worsening coastal erosion, according to new research.

Arctic Ocean was covered by kilometre-thick ice shelf and filled entirely with freshwater, ‘surprising’ new evidence reveals. Extensive glaciation and lower sea levels cut off Arctic from ...

Earlier this year a group of explorers found themselves on thin ice. Their special F-150 sunk to the depths below. Here's how they got it back.

But it is also an unreliable indicator of just how much ice will cover the Arctic Ocean […] July is the peak of melt season in the Arctic. The sun is high and shines for almost 24 hours a day.
