Arctic’s Geology: How is GIS used for Analyzing the Structure of Arctic’s Ocean

In the past few years, researchers have been shifting their interest towards arctic regions for extracting mineral and hydrocarbon resources. If you are interested in the arctic and antarctic ocean as well as research on the lithosphere, you must already know that the arctic has a very broad and active past. Most scientists, especially from America and Australia, have been working on many research projects that help give you detailed insights into the arctic and Antarctic oceans.

The goal is to discover the history of the oceans, understand their formation and structure, and most importantly, get a clear picture of how the ocean controls weather and temperature fluctuations. Surprisingly, scientists have been able to discover a lot of crucial information about the arctic regions, including details of marine life in the ocean.

When it comes to the Antarctic, the most common questions that arise are: how did Antarctica form? What role does it play in changing the global climate? And, the biological process that is important for continuing life in the polar desert. Understanding geology is quite a complex task, especially when it comes to the arctic ocean. You are supposed to use advanced geospatial tools to conduct in-depth research on the ocean and explore the area easily. The Arctic's geology directly affects the weather and temperature.

The history of arctic land includes a volcanic history that can be traced back to as many as 28 million years ago. Some of these volcano activities took place 1000 years ago. While it has been centuries since the land experienced natural disasters, the mark can still be found.

Understand the Arctic Ocean

The Arctic had never been covered by glaciers, however, scientists found that some terrains, such as the Brooks Range, were filled with glaciers. On the north end of this region, the glaciers face mild snowfall and a very cold temperature. Scientists discovered more than 253 glaciers in this area, with 32% of the glaciers being found on the satellite imagery.

GIS (geographic information system) has been implemented in the Arctic area to help scientists discover the glaciers hidden in the land. The main purpose of the technology is to make the job of researchers easier by giving them high-resolution and 3D images of the ocean. Gone are the days when people used to conduct research on the ocean manually. The traditional methods do not work anymore. GIS consists of remote-sensing tools that are widely used for collecting detailed insights into geology.

Covered by a layer of thick ice, the arctic ocean is surrounded by sea ice (water that is frozen from the freezing temperature). Thanks to the advancements in technology. People have been able to research the arctic’s geology and understand its impact on the weather, as well as, other factors very clearly. The arctic ocean is covered with thick snow, which makes it harder for researchers to conduct a deep analysis of the subglacial lakes beneath it, as well as the marine life.
