Deep ocean currents, also known as thermohaline circulation, are driven by differences in water density, affected by temperature and salinity. These currents play a crucial role in regulating Earth's climate by redistributing heat and impacting global carbon and nutrient cycles.

Deep Ocean Currents

Thermohaline circulation is a global oceanic conveyor belt driven by differences in water temperature and salinity, which in turn affect water density. This circulation plays a critical role in regulating Earth's climate by redistributing heat and influencing atmospheric carbon dioxide levels.

Thermohaline Circulation

Differences in water density

Temperature is a measure of the average kinetic energy of the particles in a substance, which determines how hot or cold that substance feels. It plays a critical role in various scientific disciplines, influencing physical states, chemical reactions, and biological processes.

Temperature

Salinity refers to the concentration of dissolved salts in water, a critical factor influencing the density and circulation of ocean currents, as well as the health of aquatic ecosystems. It is measured in parts per thousand (ppt) and can vary significantly due to factors like evaporation, precipitation, and freshwater inflow from rivers.

Salinity

Earth's climate is a complex system influenced by various natural and human-induced factors, resulting in a dynamic environment that affects global ecosystems and human societies. Understanding the climate requires studying atmospheric patterns, ocean currents, and the balance of energy entering and leaving the planet, as these are pivotal in predicting changes and impacts of climate variability and change.

Global carbon cycles

Nutrient cycles are the natural processes that recycle essential elements such as carbon, nitrogen, and phosphorus through the environment, organisms, and back to the environment. These cycles are crucial for maintaining ecosystem health and productivity, as they ensure the continuous availability of nutrients required for various biological processes.
