Marine iodine emissions in a changing world Open
Iodine is a critical trace element involved in many diverse and important processes in the Earth system. The importance of iodine for human health has been known for over a century, with low iodine in the diet being linked to goitre, creti…

Oxidation of iodide to iodate by cultures of marine ammonia-oxidising bacteria Open
Reaction with iodide (I-) at the sea surface is an important sink for atmospheric ozone, and causes sea-air emission of reactive iodine which in turn drives further ozone destruction. To incorporate this process into chemical transport mod…

Global sea-surface iodide observations, 1967–2018 Open
The marine iodine cycle has significant impacts on air quality and atmospheric chemistry. Specifically, the reaction of iodide with ozone in the top few micrometres of the surface ocean is an important sink for tropospheric ozone (a pollut…

Pyrogenic iron: The missing link to high iron solubility in aerosols Open
Air pollution creates high Fe solubility in pyrogenic aerosols, raising the flux of biologically essential Fe to the oceans.

Seasonal Variability and Fractionation of P-Based Nutrients in Setiu River Basin, Terengganu, Malaysia Open
A seasonal study of phosphorus (P)-based nutrients was carried out in Sungai Setiu basin which is located in the southern region of the South China Sea (Malaysia) from July 2010 until June 2011.Parameters measured were dissolved inorganic …
A reevaluation of the magnitude and impacts of anthropogenic atmospheric nitrogen inputs on the ocean Open
We report a new synthesis of best estimates of the inputs of fixed nitrogen to the world ocean via atmospheric deposition and compare this to fluvial inputs and dinitrogen fixation. We evaluate the scale of human perturbation of these flux…
What proportion of riverine nutrients reaches the open ocean? Open
Globally, rivers deliver significant quantities of nitrogen (N) and phosphorus (P) to the coastal ocean each year. Currently, there are no viable estimates of how much of this N and P escapes biogeochemical processing on the shelf to be ex…
Atmospheric transport of trace elements and nutrients to the oceans Open
This paper reviews atmospheric inputs of trace elements and nutrients to the oceans in the context of the GEOTRACES programme and provides new data from two Atlantic GEOTRACES cruises. We consider the deposition of nitrogen to the oceans, …
Drivers of summer oxygen depletion in the central North Sea Open
In stratified shelf seas, oxygen depletion beneath the thermocline is a result of a greater rate of biological oxygen demand than the rate of supply of oxygenated water. Suitably equipped gliders are uniquely placed to observe both the sup…
