The researchers collected water samples from beneath the ice during the polar night to study plant plankton and bacteria and better understand how the marine ecosystem functions under extreme conditions.
What was the name of the research vessel that spent a winter trapped in Arctic ice to capture key climate data in 2019 and 2020?
The year-long project began last October, when the Polarstern icebreaker cut its engines in the Arctic Ocean north of Siberia and became frozen in a giant slab of ice. It has been drifting ever since, with teams of scientists travelling to and from the vessel using icebreakers and aircraft.
Can ships get stuck in ice?
Among the most serious hazards is becoming surrounded and stuck in sea ice requiring the assistance of other vessels, such as an icebreaker, to break free. When vessels become beset in ice, pressure on the ship’s hull, so-called ice-loading, can increase causing severe structural damage.
What kind of data did the scientists collect in the Arctic?
To overcome the shortcomings of in situ observations, polar orbiting satellites began collecting data over the Arctic (as well as the Antarctic) in the 1970s. Scientists use radiometry data and visible imagery collected from the satellites to determine the sea ice extent.
What are the effects of the ice melt?
Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
Is the North Pole still frozen?
The North Pole is presently covered by sea-ice all year. Each summer, the area of sea-ice coverage decreases and grows again in winter. However, as a result of global warming, the overall area of the Arctic Ocean covered by sea-ice has reduced rapidly over the past few decades.
Is the Arctic just made of ice?
Snow Cover over Sea Ice Because the Arctic Ocean is mostly covered by ice and surrounded by land, precipitation is relatively rare. Snowfall tends to be low, except near the ice edge. Antarctica, however, is entirely surrounded by ocean, so moisture is more readily available.
What do you call a ship stuck in ice?
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Icebreakers clear paths by pushing straight into frozen-over water or pack ice.
How did old ships break ice?
While other vessels feature a pointed bow, the icebreakers’ bow will be designed in a more rounded structure to help the vessel break the ice using its weight and also to ride over it. The pointed hull of a normal ship helps it to slice through the waves and reduce friction between ship and water.
How do scientists measure global warming?
Climate change is most commonly measured using the average surface temperature of the planet. Year-on-year, natural fluctuations can be seen on top of this long-term warming. For this reason, scientists traditionally use a period of at least 30 years to identify a genuine climate trend.
What are scientists doing in the Arctic?
To study the Arctic, researchers sometimes travel to the field to conduct experiments or make observations. They study the properties of snow and sea ice, digging snow pits to examine the properties of snow, or measuring the thickness of sea ice by hand to determine how the ice cover is changing.
How does global warming affect the melting of ice?
Melting ice causes more warming. As global warming causes more snow and ice to melt each summer, the ocean and land that were underneath the ice are exposed at the Earth’s surface. Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere.
