In this first module, we look at the various zones of the ocean, both in terms which zones are the most bright and which are the most productive. We first: (i) look at the zones of the ocean based on how much light can access them, highlighting the photic zone as a crucial area where producers can survive and photosynthesise; we reference (ii) John Ryther as a pioneer in our understanding of the zones of productivity in the ocean; following this (iii) we focus on the upwelling as a key zone for productivity, as well as the Peruvian Anchovetta as an example of an upwelling zone; we then (iv) finish up by discussing John Rythers predictions on fishery limits.
