The ocean’s water column (a conceptual pillar of water measured from the ocean’s surface to the seafloor) is often divided into five zones — the epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic zones (see Figure 4-2). The divisions generally correspond to differences in depth, amount of sunlight, temperature, pressure, nutrients, and organisms that live in those zones. In the following sections, we take a deep dive into each of the five vertical ocean zones.
