When did Operation IceBridge start?
2009
NASA’s Operation IceBridge (OIB) was an airborne mission to survey changing land and sea ice across the Arctic, Antarctic, and Alaska that operated between 2009 and 2021.
When did Operation IceBridge end?
Operation IceBridge concluded its final polar flight on November 20, 2019. The Operation IceBridge data collection is the second of three NASA missions providing continuous observations of Earth’s fast-changing polar regions.
What does IceBridge study annually?
NASA’s Operation IceBridge Completes Eleven Years of Polar Surveys. For eleven years from 2009 through 2019, the planes of NASA’s Operation IceBridge flew above the Arctic, Antarctic and Alaska, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers and ice sheets.
What is the purpose of Operation Ice Bridge?
Using a fleet of research aircraft, NASA’s Operation IceBridge images Earth’s polar ice to better understand connections between polar regions and the global climate system. IceBridge studies annual changes in thickness of sea ice, glaciers and ice sheets.
What is Ice Bridge mission?
IceBrdige – Flying over the poles to monitor critical areas of Earth’s ice sheets, glaciers and sea ice. Credits: NASA/Studinger. IceBridge is the largest airborne survey of Earth’s polar ice ever flown. It yields an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice.
What is IceBridge?
IceBridge is the largest airborne survey of Earth’s polar ice ever flown. It yields an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice.
How are ice bridges formed?
Driven primarily by atmospheric stresses, these ice bridges are formed when sufficiently thick ice “jams” during the course of its flow between land masses, resulting in a region of stationary compacted ice that is separated from a region of flowing open water (a polynya) by a static arch.
How long is the ice bridge to Mackinac Island?
The trio embraced the day’s overcast skies, calm winds and below-freezing temperatures to make the 3.5-mile trek on fat-tire mountain bikes across an ice bridge that stretches across the Straits of Mackinac and onto the shores of Mackinac Island.
What is an ice bridge on cell tower?
The waveguide bridge, also known as an ice bridge or transmission line bridge, is a hot-dipped galvanized support structure used to horizontally secure transmission lines from the tower to the equipment building or BTS cabinet.
Where was the ice bridge?
It is widely believed that the first migrants to North America arrived approximately 14,000 years ago, having trekked across a land bridge spanning the Bering Strait from Siberia to Alaska.
What is an ice bridge called?
The Bering land bridge is a postulated route of human migration to the Americas from Asia about 20,000 years ago. An open corridor through the ice-covered North American Arctic was too barren to support human migrations before around 12,600 YBP.
How many lives were lost building the Mackinac Bridge?
Five workers died during the construction of the Mackinac Bridge. One died in a diving accident; one fell in a caisson while welding; one fell a couple of feet into the water and drowned; and two fell from a temporary catwalk near the top of north tower.
What are the drum looking things on towers?
You will often see a parabolic dish or two on a cell tower. It will likely be a grid style or a solid dish, but you might see something that looks like a big bass drum. These are all species of microwave antennas, and they are being used to backhaul traffic to the mobile switch sitting in the central office.
What was the ice bridge called?
The Bering land bridge
The Bering land bridge, also called Beringia, connected Siberia and Alaska during the late Ice Age. It was exposed when the glaciers formed, absorbing a large volume of sea water and lowering the sea level by about 300 feet.
Do cell towers have IP addresses?
Mobile devices and cell towers communicate with each other with Global System for Mobile Communications (GSM – see wikipedia article), which does not provide internet protocol, and thus not an internet protocol (IP) address.
What is Operation IceBridge NASA?
About IceBridge. Using a fleet of research aircraft, NASA’s Operation IceBridge images Earth’s polar ice to better understand connections between polar regions and the global climate system. IceBridge studies annual changes in thickness of sea ice, glaciers and ice sheets. ICEBridge bridges the gap between the ICESat missions.
What is Operation IceBridge data collection?
The Operation IceBridge data collection is the second of three NASA missions providing continuous observations of Earth’s fast-changing polar regions.
What can we learn from Operation IceBridge?
By revealing the topography of the underlying bedrock, Operation IceBridge data shed light on the complex interactions between ice and the land beneath. The aircraft missions also documented seasonal growth and melt of sea ice, including tracking interannual variations in sea ice extent and thickness.
What is IceBridge and why is it important?
In addition, IceBridge collects critical data used to predict the response of earth’s polar ice to climate change and resulting sea-level rise. IceBridge also helps bridge the gap in polar observations between NASA’s ICESat satellite missions. See the following websites for more Operation IceBridge information:
