Global estimate of mesopelagic mesozooplankton biomass

Abstract

Paper summary generated by OpenAI: This study presents the first global estimates of mesopelagic mesozooplankton biomass (MMB), utilizing particulate organic carbon (POC) and net primary productivity (NPP) as key predictors. By comparing these estimates with existing data, the researchers established a significant relationship between epipelagic and mesopelagic zooplankton biomasses. The findings indicate that global MMB ranges from 0.20 to 0.91 PgC, with higher biomass observed in specific regions of the northern hemisphere and areas with rich POC stocks. The study highlights the importance of mesopelagic zooplankton in marine ecosystems and provides insights into their spatial distribution and ecological roles.
