Desalination is the process of removing salt and other minerals from seawater to make it safe for drinking, irrigation, and other purposes. This process is becoming increasingly important as fresh water resources become scarce in many parts of the world. The process typically involves filtering seawater through a membrane that removes the salt and other…
Ocean acidification refers to the decrease in pH levels of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. This process occurs when CO2 from the burning of fossil fuels and deforestation reacts with seawater, forming carbonic acid and lowering the ocean’s pH. This in turn can impact the ability…
Ocean plastic pollution is an increasing concern that refers to the buildup of plastic waste in the oceans and seas. This pollution is brought about by numerous sources, including litter on beaches, sewage discharges, and plastic debris from ships and boats. The plastic waste in the ocean takes a considerable amount of time to decompose…
Marine corrosion refers to the degradation of materials (typically metals) due to their exposure to marine environments, such as saltwater and air. This type of corrosion can occur on boats, ships, offshore structures, and coastal infrastructure. The main causes of marine corrosion are electrolysis, galvanic corrosion, and pitting corrosion. Electrolysis occurs when two dissimilar metals…
Sustainable coastal development is the process of planning and managing coastal areas in a way that balances economic development with the protection of natural and cultural resources. This approach seeks to minimize negative impacts on the environment while promoting social and economic well-being for coastal communities. One key aspect of sustainable coastal development is the…
An offshore oil rig is a large structure with facilities for drilling oil wells and extracting petroleum from beneath the ocean’s surface. These structures can be either fixed platforms, which are built into the seafloor, or floating platforms, which are buoyant and can be moved from location to location. Offshore oil rigs typically include living…
