Abstract: The classic model of fjord renewal is complicated by tidewater glacier fjords, where submarine melt and subglacial discharge provide substantial buoyancy forcing at depth. Here we use a suite of idealized, high-resolution numerical ocean simulations… read more here.

Abstract: Abstract We used radiogenic and stable Sr isotope ratios (87Sr/86Sr and δ88/86Sr) to examine controls on solute acquisition in subglacial discharge from the Russell Glacier, a land-terminating lobe of the Greenland Ice Sheet (GrIS) located… read more here.

DOI: 10.1029/2022gl102689
Abstract: Subglacial discharge emerging from the base of Greenland's marine‐terminating glaciers drives upwelling of nutrient‐rich bottom waters to the euphotic zone, which can fuel nitrate‐limited phytoplankton growth. Here, we use buoyant plume theory to quantify this… read more here.
