Surprise in the Gulf of Aqaba: intense dust inputs are not a source of trace metals to seawater!
Benaltabet and his colleagues present a 2-year time series of several trace metal concentration profiles sampled at a daily resolution.

Time series thorium-230 data reveal scavenging intensification over the last 15 years in the Arctic Ocean
Authors demonstrate that the later hypothesis is likely explaining thorium-230-depletion in intermediate layers of the Amundsen basin.
Has the role of atmospheric dust as a control on productivity in oligotrophic regions been overestimated?
Dust particles settling into the surface of open ocean environments are for years assumed to provide nutrients to these distant nutrient-limited areas. Torfstein and Kienast (2018, see reference below) present […]
