About this Research Topic
Advances in observational platforms, sampling and analytical methods, and modeling capabilities are providing new insights on the ocean’s particle cycle and the roles that mid- and deep-water ecosystems play in the particle flux attenuation and transformation with depth.
The second volume of this multidisciplinary Research Topic will bring together new research articles under themes related to biology, geochemistry, oceanography, and modeling to provide a broad overview of current research on the diverse processes and pathways that drive the downward flux of material and energy through the ocean’s interior.
This Research Topic is envisioned to include:
(1) topical articles on the biological pump, including comparison of downward flux pathways, the influence of ecosystem structure on export and transfer efficiencies, and articles highlighting knowledge gaps in our current understanding of particle flux and cycling processes.
(2) articles focusing on particle chemistry and reactivity and its evolution with depth, and on the roles of macro- and micro-organisms in affecting particle transformations in the interior ocean.
(3) studies evaluating the physical, chemical, and biological stressors that impact the particle flux, under both present and future ocean scenarios.
(4) mini-reviews, including syntheses of particle flux studies at regional, basin and global scales.
Keywords: elemental cycles, oceanic particle flux, deep ocean, biogeochemistry, organic carbon, mineralization
