GEOG 310 Lecture Notes - Lecture 24: Continental Shelf, Marine Habitats, Upwell
Document Summary
Starts from phytoplankton (small marine creatures which capture solar radiation and then become biomass) Then becomes zooplankton (they eat phytoplankton and other zooplankton) Leads to feeders/forage fish and finally predatory fish. We need nutrients (i. e. a food source) and/or sunshine (as phytoplankton"s are converting solar radiation to biomass) to create marine life. What species we find is dependent on local conditions in. Most likely in shallow and coastal waters --> due to the presence of great solar radiation. Fish resources would most likely be found in tropical climates (near the equator) Currents with more movement means that are more upwelling of nutrients --> this will change throughout the seasons, leads to shifting. Up swelling is most likely found in the edge of continental masses (as water gets forced upwards) This is areas where there are a lot of nutrients. Ocean topography --> currents will follow ocean topography (i. e. according to continental shelves), which also affects where fish resources are found.
