Ice tame: what is it, how is it forms and difference with an iceberg

An ice weathering, also called iceberg, is a Huge floating ice mass that has detached from a glacier or an ice platform and ends in The ocean. These ice blocks can vary in size, from small fragments to huge structures that exceed the hundreds of meters high and kilometers of extension under the water.

Most ice casters are composed of fresh water, since they are formed from terrestrial glaciers. Although only one Little part of the weathering is visible On the surface of the water (approximately 10%), most of its volume is submerged, which can make them dangerous for navigation.

The starts are common in polar regions, such as Arctic and Antarctica, and their existence is linked to natural processes of detachment and melting. In addition, they are Important climate change indicatorssince the increase in global temperatures influences their formation and the speed with which they melt.

Ice starts are classified into various types according to their size, shape and origin. We will see what are the main types of ice snacks that exist according to their characteristics:

Ice icebergs according to its size

• Bergy Bits: They are small weathering, approximately 1 to 5 meters above the water and less than 15 meters in length. Their reduced size makes them difficult to detect from vessels.
• Growlers: They are even smaller than the Bergy Bits, with less than 1 meter visible on the water and a length of up to 5 meters. They often have a dark green color due to trapped air bubbles and the reflection of surrounding water.
• Giant Icebergs: They are huge blocks that can exceed 75 meters high and hundreds of meters in length. Their colossal size makes them imposing and sometimes dangerous structures.

Ice icebergs according to its form:

• Tabular weather: They have a flat shape, similar to a table. They originate mainly when large ice platforms in Antarctica fracture and give off. These starts usually have vertical sides and a wide and flat upper surface.
• Non tabular weather: They have irregular forms, often more common in regions such as the Arctic.

Ice starts according to its origin:

• Terrestrial glaciers: They are the most common and form when a glacier reaches the sea, where contact with salt water causes the detachment of large blocks of ice.
• Floating ice platforms: These starts are usually tabular and come from the ice platforms that surround the Antarctica.

The formation of an ice snack is a natural process that begins in the polar regions, where temperatures are low enough to allow snow and ice compaction and compaction over time.

1. Glacier formation. This occurs when accumulated snow does not melt completely during the summer and is compacted over time due to its own weight. The lower compressed snow layers are transformed into dense ice, eliminating the trapped air and creating a glacier.
2. Glacier movement. The glaciers are not static, but move slowly due to the force of gravity and pressure of their own weight. This movement can lead to the glacier to the coast or to the edge of a floating ice platform.
3. Fracture of the glacier and creation of the ice weather. When a glacier or an ice platform reaches the ocean, it interacts with the warmest salt water, which weakens its edges. This process causes cracks and fractures that finally lead to the detachment of large blocks of ice. This phenomenon is known as “Calving” and marks the birth of an ice weather. We recommend you read this other post about glacier erosion: definition, types and examples.
4. Drift in water. Once detached, the weathering floats in the ocean due to its lower density compared to water. As ice is less dense than water, approximately 10% of the weather is on the surface, while 90% remain submerged. The newly formed weathering begin to move with sea currents, wind and tides. This trip can lead them to travel great distances, especially in the case of Antarctic weather. In this link you can learn more about why ice floats in the water.

During their time in the ocean, the weathering are molded by the wind, waves and the warmer temperatures of water. This continuous wear can alter its shape and size. Eventually, the starts completely melt, releasing fresh water to the ocean. The complete process may take years, depending on the size of the weathering and environmental conditions. This natural cycle is essential for the dynamics of polar ecosystems and the balance of sea level.

The difference between an ice snack and an iceberg is mainly terminological, since both concepts are usually used as synonyms in everyday language. However, there are some subtle distinctions:

• He ice floe It is one more general expression and widely used in Spanish to describe any floating ice block that emerges from a glacier or ice platform. It is used in both scientific and informal contexts, while the word iceberg It is of English origin that translates as “ice mountain.” Its use is usually more associated with Large weather already Specific contextsas in scientific studies or international maritime navigation.
• In colloquial language, when we use the Ice Tépano Term We can refer to ice blocks Any sizefrom small fragments to large structures, but if we use the word iceberg, we are going to refer more commonly with the largest and most notable casts. In the scientific field, it tends to classify as iceberg to a block that stands out at least 5 m About water and has more than 15 m long.
