driven by differences in density from temperature and salinity, and produces deep currents. starts near pole in north and cold salty water sinks. surface water moves to replace and creates a current. deep water moves south and recharges around edge of Antarctica and splits to Indian and Pacific Ocean. dense water displace the older deeper water and upwells.
What would an increase in global temperatures result inthe thermohaline circulation could weaken and transport less heat from the equator to polar waters and Western Europe could get colder.wave mechanicsthe depth to which waves produce noticeable motion is about one half the wavelength. usually no greater than 50m because wavelengths shouldn't get above 100m. when wave height is greater than 1/7th of wavelength, wave is unstableDownwellingwater builds up and surface water eventually sinks toward bottom. nutrients aren't resupplied by the nutrient rich deep water. allows for deep ocean ventilation to occur because these waters bring dissolved oxygen down.Plates spread apartcreates mid ocean ridgesWhen one plate sinks under another platevolcano island arcs, and (ocean trenches?)When two plates slide past each othertransform boundaryMid ocean ridges vs ocean trenchesMid ocean ridges are formed by seafloor spreading and oceanic trenches are formed by subductionChlorophyll aused as a measure of standing crop of phytoplankton because it is a direct measure of photosynthesis present in total biomass.Surface area to volume ratioas an animal gets larger, its volume increases much faster than its surface does. small=large surface area to volume ratio. large= small surface area to volume ratioplankton sizecyanobacteria smallest, then coccolithophores, then diatoms, then dinoflagellates.plankton descriptionscyanobacteria: bacteria. Dinoflagellates: harmful algal blooms. Diatoms: most abundant, silica. Coccolithophores: warm and temperate seas. covered with plates.
