Abstract Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15N tracer incubations and a δ18O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer Cosmonaut Sea.

Updated Estimates of Radiocarbon‐Based Deep Ocean Circulation Age
Abstract The deep ocean circulation age based on radiocarbon was last determined almost 20 years ago, when digital archiving was not standard practice. This work updates the circulation age while making two improvements by using new nutrient data and modifying the calculation. The newly calculated circulation age is spatially more coherent and older in

Abstract Sinking biogenic particles drive the ocean biological carbon pump (BCP), yet the processes governing their formation, transformation, and fate remain poorly constrained and are difficult to represent with existing modeling frameworks. Traditional approaches either resolve particle populations as bulk distributions or simulate individual ...

Caries Café: A Method for Consolidating and Co‐Constructing Knowledge of Caries
ABSTRACT Introduction Dental caries is multifaceted and requires dental undergraduates to receive training in underlying science, risk factors, disease prevention, and treatment. Caries content features at many different points in a Bachelor of Dental Surgery (BDS) programme, making it a large task to consolidate and assimilate in clinical practice ...
