Remote sensing of these organisms is used to measure the distribution of carbon dioxide in the world's oceans. For 10 points each:
[10m] Name these phytoplankton, whose namesake spherical shell of calcified scales is detected in remote sensing. Along with foraminifera, these phytoplankton are the major component of calcareous oozes.
ANSWER: coccolithophores
[10h] In this system for oceanic carbon regulation, dissolved inorganic carbon circulates from the sea surface into the deep sea via thermohaline circulation and back up via upwelling. It is contrasted with a biological version, which involves plankton biomass sinking as marine snow.
ANSWER: solubility pump [prompt on pump]
[10e] Coccolithophores are increasingly struggling to produce their shells due to this process, caused by increased atmospheric carbon dioxide dissolving into the ocean. This process causes coral bleaching.
ANSWER: ocean acidification
