Iceberg 'doodles' trace climate history

It is as if a child has been doodling with large coloured crayons.
What you see are actually the great gouge marks left on the seafloor when the keel of a giant block of ice has dragged through the sediments.
The arcs and loops record the movement of the berg as it turns about, caught in the wind, currents and tides.
This "ice art" is from a stunning new collection of images that detail how glacial action has shaped the ocean floor in Earth's polar regions.

It's time to visit 'Iceberg Alley' in Canada

Residents view the first iceberg of the season as it passes the South Shore, also known as "Iceberg Alley", near Ferryland Newfoundland, Canada April 16, 2017. The best time to view icebergs are during the spring and early summer months, with the "bergs" most plentiful in April and May.

Iceberg tourists flock to Newfoundland town

A small town in Newfoundland, Canada, has become a sudden tourist spot thanks to a new visitor - one of the first icebergs of the season.
Canada's CBC News said that over the Easter weekend, the Southern Shore highway near the town of Ferryland was blocked with traffic as photographers - professional or amateur - pulled up to snap the hulking ice mountain.

Unusually large swarm of icebergs drifts into shipping lanes

More than 400 icebergs have drifted into the North Atlantic shipping lanes over the past week in an unusually large swarm for this early in the season, forcing vessels to slow to a crawl or take detours of hundreds of miles.

Iceberg patrol gains faster updates from orbit

The international iceberg patrol service set up after the sinking of the Titanic is now able to track drifting ice from orbit more swiftly through ESA-backed cloud computing.
The icebergs drifting in transatlantic shipping lines typically break off from the Greenland ice sheet before being carried into Baffin Bay. From there, they typically either become grounded or continue southwards. Most are gradually weathered away, but some can endure dangerously far south.

Giant icebergs play 'major role' in ocean carbon cycle

Giant icebergs could be responsible for the processes that absorb up to 20% of the carbon in the Southern Ocean's carbon cycle, a study suggests.
Researchers say mel****er from these vast blocks of ice release nutrients into the surrounding waters, triggering plankton blooms that absorb the carbon.

Icebergs 'have sound signature'

Listening to icebergs could help to assess the extent of glacier melt, scientists report.
Researchers in Poland and the UK have found that different types of icebergs have their own acoustic signature as they calve away from the ice.

Texas A&M Researchers Rethink Massive Iceberg Shifts That Have Occurred In North Atlantic

Some Heinrich events - periodic massive iceberg surges into the North Atlantic that were previously thought to have weakened the global ocean conveyor belt circulation and sent Earth's climate into the deep freeze - may actually have been caused by changes in atmospheric circulation patterns, say a team of researchers that includes two Texas A&M University professors.

Study Examines Iceberg Shifts In North Atlantic

Some Heinrich events - periodic massive iceberg surges into the North Atlantic that were previously thought to have weakened the global ocean conveyor belt circulation and sent Earth's climate into the deep freeze - may actually have been caused by changes in atmospheric circulation patterns, say a team of researchers that includes two Texas A&M University professors.
Matthew Schmidt, associate professor of oceanography, and Ping Chang, professor of oceanography and atmospheric science and director of the Texas Center for Climate Studies, along with colleagues from Georgia Tech, Princeton, the Woods Hole Oceanographic Institution, the University of Cambridge and Germany's University of Bremen, have had their findings published in the latest issue of Nature Geoscience.

Is this the iceberg that sank the Titanic?

One of history's greatest whodunnits may have finally been solved with the appearance of a photo depicting the iceberg the Titanic could have hit.
An American auction house is selling a black-and-white picture of an iceberg taken by the captain of the SS Etonian two days before the sinking of the Titanic.
