Abstract/Contents

Abstract: Oxygen minimum zones (OMZs) are regions of the ocean with extremely low levels of O2 and can arise due to multiple chemical and biological processes. Oxygen depletion in OMZs is not completely understood but is believed to arise because of upwelling of old, oxygen-poor water, bacterial decomposition of carbon from the mixed layer, and respiration of organisms in regions of the ocean like the deep scattering layer (DSL). Because OMZs are expanding with a warming atmosphere and warming ocean waters, it has become increasingly important to understand the impact of changing oxygen levels on organisms in the ocean. In this study, we examine the influence of expanding OMZs on zooplankton density and biodiversity in shallow ocean layers, as well as examine the relationship between oxygen levels and zooplankton communities within OMZs, where oxygen is largely depleted.
