GO_Human Impact on Geological Oceanography Lesson
Geological oceanography offers us a remarkable lens through which to examine the dynamic interplay between Earth's processes and the vast oceans that cover our planet. One critical aspect of this field is its role in helping us understand and address the complex issue of rising sea levels. Human activities have already contributed significantly to this phenomenon through the burning of fossil fuels, which releases greenhouse gases into the atmosphere and leads to an average global temperature increase. As temperatures rise, polar ice caps and glaciers melt, adding freshwater to the oceans and causing sea levels to increase.
Geological oceanographers play a crucial role in monitoring these changes and providing valuable data for scientists and policymakers working to mitigate the impacts of rising sea levels on coastal communities.

The extraction of geological resources from beneath the ocean floor is a complex and multifaceted process that involves various industries, primarily oil and gas exploration and mineral mining. While these activities are essential for meeting global energy demands and accessing valuable minerals, they can have significant and often detrimental impacts on the marine environment.
How do we extract these resources?
Oil and Gas Extraction
In the quest for fossil fuels, offshore drilling platforms are established in coastal and deep-sea areas. These platforms use a combination of drilling techniques to access oil and natural gas reservoirs beneath the seabed. During drilling, there is always a risk of oil spills and leaks, which can have catastrophic consequences for marine ecosystems. Oil spills release toxic substances into the ocean, harming marine life and coastal habitats. Cleanup efforts are often challenging and may not fully mitigate the environmental damage. Additionally, the infrastructure associated with offshore drilling, including pipelines and transportation vessels, can disturb the ocean floor and marine life.
Mineral Mining
The ocean floor is also a source of valuable minerals such as polymetallic nodules, manganese nodules, and rare earth elements. Mining operations involve specialized machinery and remotely operated vehicles that collect these minerals from the seabed. The disturbance caused by mining can result in habitat destruction and the resuspension of sediments, which can smother marine life and disrupt local ecosystems. Furthermore, the release of chemicals and waste materials during the mining process can lead to water pollution and harm marine organisms.
In light of these environmental impacts, geological oceanographers and environmental scientists play a crucial role in studying the effects of resource extraction on the ocean and advocating for sustainable practices. This involves developing technologies and strategies to minimize harm, monitoring the health of marine ecosystems, and working with industry and policymakers to establish regulations that promote responsible resource extraction while safeguarding the delicate balance of the ocean environment.
In our ever-changing world, understanding the critical role that geological oceanography plays in addressing global challenges, such as sea level rise and responsible resource extraction, is paramount. By advancing our knowledge of Earth's geological processes and their interaction with the oceans, this field empowers us to make informed decisions and take meaningful actions to protect both our planet's delicate ecosystems and the well-being of coastal communities around the world.
Geological oceanography is vital for comprehending the link between human-induced sea level rise and environmental consequences. It also addresses the environmental impacts of resource extraction from the ocean floor and advocates for sustainable practices.
