NASA image of a tabular iceberg of the ice platform Larsen C.NASA
NASA has just shared an amazing image of an almost perfect rectangular iceberg in Antarctica. The monolithic ice slab, floating just above the Larsen C ice floe, does not seem natural considering the 90-degree angles.
NASA took the picture As part of Operation IceBridge, one mission is to represent the Polar Regions of the Earth to understand the evolution of ice (thickness, location, accumulation, etc.) in recent years.
Although the iceberg is strange enough to watch, it is an entirely natural phenomenon. Most of us have the habit of seeing angular iceberg images with just a small tip coming out of the water. However, there is a totally different type of iceberg called tabular iceberg.
Tabular icebergs have steep, almost vertical sides and a flat plateau. Tabular icebergs generally stand out from ice shelves, which are tabular bodies of thick ice. When there is a clean calf of the iceberg, the angles can be close to 90 degrees. In this case, the iceberg is probably not very old, because the wind, the waves and the spray will win over the sharp edges of this iceberg and will complete it, Kelly Brunt NASA scientist.
As you may know, only 10% of the iceberg is above the surface of the ocean when it floats. However, in this particular image, it is unclear whether the iceberg floats completely or is partially seated at the bottom of the ocean.
Although this iceberg has not yet been measured, some tabular icebergs can be incredibly large. The largest recorded iceberg in the world is the Iceberg B-15, which is 183 km long and 23 km wide. The tabular iceberg, which was larger than the island of Jamaica, is slender from the Ross Ice Shelf in 2000.

To put the two icebergs in perspective, the map above highlights the location of the Larsen C Ice Shelf. Towards the bottom of the map, you'll notice the Ross ice floe, which produced the largest iceberg Of the history.

The ice packs are formed where the earth meets the ocean. When the ice flows from the landmass to the ocean, it eventually spreads to the ocean, floating in some places and partially supported by the ocean floor. The ice that rests on the ocean but is attached to the earth is a patch of ice. A normal process for these ice platforms is calving, detaching the distal ice from the largest ice platform.
NASA intends to study this calving process as part of the IceBridge operation in order to measure the meltdown due to global warming. As the planet heats up, these pack ice are much more likely to empty and melt floating in the ocean. This is a key variable in the continuous rise in sea level that NASA has measured for decades.
