Glaciology is the study of ice and its various natural formations on Earth and other celestial objects such as planets, moons, and other locations. On Earth, this research includes glaciers and large polar ice sheets, but is not limited to them. Glaciology is important not only from an Earth science standpoint, but also from a meteorological and astronomical standpoint. As a result, it is regarded as a multidisciplinary science, and glaciologists frequently require training in a variety of scientific disciplines.
The study of ice on Earth is also multifaceted due to the complexities and interdependence of various processes on the planet. Any study’s overall goal or objective is determined by the scientist and the area of interest. Some people may be curious about earlier periods of Earth’s geological history. Others may be more concerned with the current impact of climate change, or global warming, on the Earth.
One of glaciology’s main goals is to figure out what the Earth’s atmosphere was like eons ago. Similarly to how different layers of rock can reveal information about the Earth’s natural history, ice can do the same. Scientists can almost precisely determine the composition of the Earth’s atmosphere using core samples. When compared to the geologic record, this can help determine what different species require for optimal survival.
Even if there are no glaciers or ice sheets in the current area, glaciology can help explain why the Earth has certain landforms. For example, glaciers carving paths as they receded from the landscape can explain many of the rolling hills in the Midwest of the United States and Canada. Similarly, melting glacier water may be responsible for some of the world’s deepest gorges, such as the early history of the Niagara Gorge near the US-Canada border.
Glaciology may not only provide answers about the Earth, but it may even outweigh what the field has to say about other planets and celestial bodies to humans. Scientists will have a good starting point in their search for extraterrestrial life if they can understand and identify which of these have ice. Of course, this life would be very simple in nature, but it would still provide an answer to one of humanity’s oldest questions.
Those who are interested in glaciology will most likely find the most job opportunities in educational or research institutions. Because these jobs frequently require a graduate degree, students should expect to spend more than four years in college. Prospecting for oil, minerals, or other natural resources may provide some opportunities for those interested in working in the private sector. The ice can often reveal which resources are plentiful in a given area.
