The Surface Ocean-Lower Atmosphere Study (SOLAS) is a global research network dedicated to advancing coupled oceanographic and atmospheric science, a field that requires both interdisciplinary and globally distributed expertise. Since 2004, SOLAS has fostered an international interdisciplinary scientific community through coordinated science and capacity sharing activities. This paper outlines how SOLAS 3.0 (2026–2035) will bu...

The surface ocean is the main source of iodine to the atmosphere, where it plays a crucial role including in the catalytic removal of tropospheric ozone. The availability of surface oceanic iodine is governed by its biogeochemical cycling, the controls of which are poorly constrained. Here we show a near two-year time series of the primary iodine species, iodide, iodate and dissolved organic iodine (DOI) in inner shelf marine...
