Bowhead habitat

Polar Regions

Polar Regions are icy extremes found on the northern and southern geographical poles of planet earth. These frozen waste lands are known as the polar ice caps. This area is defined by a circle which has a radius latitude of 23° 28’ from the Pole centre.   This habitat is the coldest in the world because temperature ultimately depends on solar radiation, 89-90% of which is reflected from the albedo (whiteness) icy surface, therefore this area is maintain a temperature no higher then 0°C. The systemic winds of this habitat are latitudinal bound and has contribute to the constant extremes of this environment.. The latitudinal wind band is westerly winds on the fringes and easterly winds close to the poles (Blix, 2005). This habitat is highly productive region having a vital role in the physical, chemical and biological cycle and containing the majority of the biological and mineral resources of the world. The species that reside in this frozen habitat have unique adaptations for survival (Brown, et. al. 1980). The northern ice cap is called The Arctic (mainly ocean) and the southern ice cap is called The Antarctica (continent).

One of the species that has adapted to survive in this frozen paradise is the Bowhead Whale. This whale spends all year in the polar ice caps which is unique as most whales (like their close relative Right Whale) migrate to tropical waters to rear their young. The Bowhead Whale can only be found in the Arctic (Northern pole). These whales are also threatened by many human activities. Their direct human threat are native whale hunters that live in the  Arctic region use whales for traditional means. In this habitat of extremely demanding environmental conditions, scientific surveys are hazardous and expeditions on these species are rare.
