Thermohaline circulation

Cards (10)

  • thermohaline circulation is the global oceanic flow that is driven by variations in temperature and salinity
  • thermohaline circulation is the primary mechanism for distributing heat across the planet
  • thermohaline circulation moves warm water from the equator towards the poles and colder water from the poles towards the equator, this creates the circulation effect.
  • transfer of hear influences weather patterns, ocean temperatures and wind currents
  • colder deep currents e.g. North Atlantic deep water help to sequester CO2 and greenhouse gases this helps to mitigate climate change.
  • areas of high salinity cause denser water that will sink, this drives thermohaline circulation
  • melting of the polar ice reduces salinity and density of sea water, this can slow or halt the thermohaline circulation
  • thermohaline circulation also affects marine life, nutrients are brought up from the deep during up-welling events, this helps support marine ecosystems
  • circulation aids in distributing marine species around earth, this helps and contributes to biodiversity
  • modern technologies such as satellite data and oceanographic buoys provide insights into how thermohaline circulation is affected by climate change
