TL;DR: The composition of the free troposphere over the ocean is characterized by the presence of various clusters, some of which are thought to be precursors to new particle formation. The presence of these clusters is influenced by both terrestrial and marine sources.

Iodate reduction by marine aerobic bacteria
Ken Kine,Shigeki Yamamura,Seigo Amachi +2 more
TL;DR: Marine aerobic bacteria, such as Roseovarius azorensis, Notoacmeibacter marinus, and Aliiroseovarius sediminilitoris, can reduce iodate to iodide under oxygen-limited conditions, induced by environmentally relevant iodate levels, contributing to iodide production in marine surface waters.

TL;DR: In this paper, the authors presented a new version of the chemistry-climate model SOCOL-AERv2 supplemented by an iodine chemistry module and performed three 20-year ensemble experiments to assess the validity of the modeled iodine and to quantify the effects of iodine on ozone.

TL;DR: Results show that halogen chemistry has a significant and extensive influence on photochemical ozone loss in the tropical Atlantic Ocean boundary layer and the omission of halogen sources and their chemistry in atmospheric models may lead to significant errors in calculations of global ozone budgets, tropospheric oxidizing capacity and methane oxidation rates.

Iodine: Its possible role in tropospheric photochemistry
TL;DR: A detailed study of the photochemistry of iodine and its oxides indicates that iodine species may play an important role in the tropospheric photochemical system as mentioned in this paper, which can lead to the catalytic removal of troposphere O3, the enhancement of the NO2/NO ratio, the destruction of HxOy free radicals, and the conversion of HO2 to OH.

The significance of nitrification for oceanic new production
TL;DR: It is shown that for much of the world ocean a substantial fraction of the nitrate taken up is generated through recent nitrification near the surface, and at the global scale, nitrification accounts for about half of the Nitrate consumed by growing phytoplankton.
