Sources and distributions of a suite of underexplored particulate trace elements on the Southwest African shelf and slope

Particulate trace elements (pTEs) play key roles in marine biogeochemical cycles through their involvement in particle-seawater exchange processes and potential roles as micronutrients for the growth and functioning of phytoplankton. Here, we report on the distributions of labile and refractory particulate gallium (Ga), germanium (Ge), beryllium (Be), tellurium (Te), tin (Sn), antimony (Sb), strontium (Sr), and thallium (Tl) along the GEOTRACES GA08 transect on the southwest African shelf and of
