Glacial lake

These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks.

The area which will see the greatest increase in lake formation is the Southern Tibetan Plateau region from debris covered glaciers.

The distribution of these elements, within the lake bed, are attributed to the condition of the drainage basin and the chemical composition of the water.

[6] Biodiversity and productivity tend to be lower in glacial lakes as only cold-tolerant and cold-adapted species can withstand their harsh conditions.

Glacial rock flour and low nutrient levels create an oligotrophic environment where few species of plankton, fish and benthic organisms reside.

Glacial lakes' aesthetic nature can also stimulate economic activity through the attraction of the tourism industry.

[10] Thousands of tourists visit the Jökulsárlón glacial lagoon in Iceland annually to take part in commercial boat tours and every two to four years thousands visit the Argentino glacial lake in Argentina to witness the collapse of the cyclically formed arch of ice from the Perito Moreno glacier, making it one of the largest travel destinations in Patagonia.
