Ice formations, those magnificent natural sculptures of frozen water, are a common sight for those residing in the polar regions or individuals with a profound interest in these icy landscapes. While many have admired these colossal frozen structures in photographs, a comprehensive understanding of their genesis and characteristics often remains elusive. This primer aims to demystify these remarkable natural wonders, elucidating their formation process, distinguishing them from other ice types, and showcasing their diverse manifestations.
Icebergs originate primarily from tidewater glaciers, which are massive ice bodies that extend into the ocean. As these glaciers continuously advance, fragments of ice calve or break off from their edges, subsequently drifting away as icebergs. This process, known as calving, is a fundamental mechanism by which glaciers lose mass and contribute to the formation of icebergs. Glaciers that do not reach a body of water, such as those that terminate on land, are unable to produce icebergs. However, even land-terminating glaciers can contribute to the formation of smaller ice structures, especially if they descend into a lake. For instance, Berg Lake in the Canadian Rockies occasionally features small icebergs derived from the alpine glacier that plunges into its waters.
For a significant portion of the year, icebergs often become encased within the sea ice. During this period, they remain largely stationary. A notable phenomenon observed around these immobilized icebergs is the formation of a 'moat' – an area of thinner ice or even open water that surrounds the iceberg. This moat often attracts local wildlife, such as seals, due to the more accessible conditions. Consequently, predators like arctic wolves and polar bears frequently investigate these icebergs, drawn by the presence of potential prey. As the warmer months approach, typically around early July, meltwater puddles form on the surface of the sea ice. This meltwater gradually erodes the structural integrity of the continuous sea ice, eventually causing it to fragment into individual ice floes. At this point, the icebergs, once imprisoned, become surrounded by open water and begin to drift freely.
The appearance of icebergs can be strikingly diverse, often resembling intricate natural art forms. These variations in shape and size are influenced by factors such as the parent glacier's characteristics and the subsequent erosive forces of wind and water. Some icebergs exhibit unique features, such as 'keyholes,' which are essentially drainage channels that were present within the parent glacier. While visually appealing, navigating through these keyholes by boat is extremely hazardous due to the unpredictable nature of ice movement and potential for calving events. However, in colder seasons, entering such formations, particularly if they are frozen in place, can be safer for observational purposes, although caution is always advised when exploring any glacial or ice-related features.
A critical distinction to understand is the difference between icebergs and ice floes. Icebergs, as previously mentioned, are composed of freshwater, having originated from glaciers. In contrast, sea ice is formed from the freezing of ocean water, making it saline. Sea ice is generally flat, though near coastal areas, tidal forces can create more uneven, choppy sections. However, these formations are never as massive or imposing as icebergs. Similarly, multiyear ice, which is sea ice that has survived at least one melt season, is also distinct from icebergs. While multiyear ice can become exceptionally thick and rugged due to repeated freezing and compression by currents and tides, it is still fundamentally different from glacier-derived icebergs. The Arctic once featured vast expanses of multiyear ice and even massive ice islands, which were essentially super-icebergs formed from the breaking off of ice shelves. These ice islands, a mix of glacier and sea ice, were stable enough to host scientific camps for years. However, most of these ice shelves have now vanished, a stark indicator of the changing Arctic environment.
The majority of icebergs found in the Arctic region originate from Greenland's glaciers. Propelled by ocean currents, these icebergs travel westward towards the Canadian side, then drift southward along what is colloquially known as 'Iceberg Alley.' As they journey, they gradually diminish in size due to melting. These magnificent ice structures have been observed as far south as Bermuda, demonstrating the remarkable distances they can traverse. Historically, a notorious iceberg off the coast of Newfoundland was responsible for the tragic sinking of the 'Titanic,' serving as a stark reminder of their inherent danger. It is crucial for mariners to maintain a safe distance from icebergs, generally recommended to be at least twice the iceberg's visible height, as a significant portion of their mass lies submerged beneath the water's surface, and their stability can be unpredictable, leading to sudden flips or calving events.
