Maly Lyakhovsky Island

geography Maturity 11-13 Next article →

Maly Lyakhovsky Island is a significant landmass located in the Laptev Sea. It sits within northern Russia as part of the New Siberian Islands archipelago. This island holds the distinction of being the second largest island in that specific group.

The archipelago itself carries a historical name. It honors Ivan Lyakhov, an explorer who traveled to these islands in 1773. Today, the island serves as a unique site for geological and biological study.

The geology of Maly Lyakhovsky Island is defined by complex layers of rock. The foundation consists of Mesozoic rocks from the Upper Jurassic to the lower Cretaceous periods. These rocks are specifically known as turbidites, or flysch. They include various types of stone such as sandstone, argillite, and shale. Over millions of years, these layers were deformed into folds. These folds strike in an east-northeast direction and are about 5 kilometers wide.

On top of these deep Mesozoic rocks lies a much thinner layer. This upper layer contains Pliocene to Pleistocene sediments. These sediments are made of sand and clay. They arrived through processes known as colluvial and alluvial origins. Near the coastline, these alluvial sediments change into nearshore marine sediments. These coastal layers are notable for containing fossil marine mollusks and lignitized wood. This shows that the area has experienced different environmental conditions over time.

A defining feature of the island's ground is the permafrost. This is a layer of soil that remains frozen for long periods. The permafrost on Maly Lyakhovsky Island is characterized by massive ice wedges. These wedges develop within the sediments of the island. This frozen state is a key part of the Arctic environment. It helps preserve many things found within the earth for thousands of years.

The surface of the island is covered by a landscape called tundra. This tundra is made of very low-growing plants. You will find rushes, grasses, and various forbs growing here. The ground is also covered by cryptogams, which include mosses, lichens, and liverworts. These plants often cover the surface of the ground almost completely. The soil in this tundra is typically moist and fine-grained. It often forms a hummocky shape, which means it is bumpy or uneven.

In May 2013, a scientific expedition made a major discovery on the island. A team from North-Eastern Federal University found a 10,000-year-old carcass. The remains belonged to a female mammoth. This find was especially surprising because of the condition of the remains. Scientists found liquid blood in ice cavities located below the mammoth's belly. This was remarkable because the temperature during excavation was -4.4 degrees Celsius. Researchers speculated that this find might reveal details about the cryoprotective properties of mammoth blood. This refers to how the blood could resist freezing in extreme cold.

The mammoth remains were moved to Yakutsk in the Sakha Republic of Russia. There, scientists began a detailed study of the tissues and bacteria. This work is part of a joint project involving the North-Eastern Federal University and the Sooam Biotech Research Foundation. One of the main goals of this collaboration is the cloning of a mammoth. By studying these ancient remains, scientists hope to understand the biology of extinct species. This connects the ancient history of the Arctic to modern biotechnology and genetic research.
