Question: The bioluminescent red tide blooms are caused by microscopic phytoplankton called dinoflagellates. Like all plants, they use photosynthesis to produce their food. Do you think that the dissolved oxygen concentration during the beginning of a red tide bloom increases or decreases? Why? Question: The phytoplankton of the red tide bloom end up getting eaten by small animals called zooplankton. What effect will this have on the water’s dissolved oxygen concentration? Question: All other things being equal, will surface water have a higher O2 concentration during summer when the water is warm or winter when the water is cold (but no ice)? How do you know? Question: The deep water masses in the ocean can be at temperatures near 0 C, and they acquired that temperature while exposed to the atmosphere. Do you expect them to have a high or low dissolved oxygen concentration?
