OCEAN 497 Lecture 11: 11 Biological Cycles of Ocean Memory
Document Summary
Methane at sediment surface, oxygen not present. Methane is compressed to bottom of sediments. Memories from proterozoic ocean can help predict future of current ocean. Information stored in sediments available for recall or priming. Calcite plus co2 and water makes carbonate. Removes co2 but dissolves calcite in existing shells. Dissolves calcite in sediment record in fossils. Ccd is moving up in water column. Youngest in north atlantic, oldest in north pacific. Eddy with a memory of 3 months can influence antarctic circumpolar current dynamics. Integrate memories over time to predict the future. Knowing what happened with ocean/atmosphere interaction, extreme rainfall can be predicted in the future. Use long-term memory to decide where to feed. Memory correlates with food, remembers feeding areas. Associative learning where members of food web work together, tightly coupled. Ice associated bloom of diatoms in spring in cold. Fish use coral to hide from predators, only come out to feed.
