Document Summary
Life in the deepest 3: summary & commentary. Water in an ocean"s hadal zone is characterized by extremely high levels of hydrostatic pressure. This high pressure, along with the scarcity of food sources at such depths, means that only certain types of organisms are able to live in the hadal zone. These organisms are specially equipped to live amongst the high hydrostatic pressure. They generally receive their food source from phytodetrital pulses and carrion falls (glud, wenzh fer, middelboe, oguri, Turnewitsch, canfield, & kitazato, 2013, p. 284), which are able to sink rather quickly. The research method used in this study was largely dependent on gathering data in situ so as to preserve the accuracy of measurements. Doing so meant that the team of scientists had to adapt an o2 micro-profiling instrument so that it would be capable of taking measurements while underwater and engulfed in high levels of hydrostatic pressure.
