Aluminium in an ocean general circulation model compared with the West Atlantic Geotraces cruises

Author: Van Hulten, M ; Sterl, A ; Tagliabue, A ; Dutay, J-C ; Gehlen, M ; De Baar, HJW ; Middag, R Date: Oct 2013 A model of aluminium has been developed and implemented in an Ocean General Circulation Model (NEMO-PISCES). In the model, aluminium enters the ocean by means of dust deposition. The internal oceanic processes are described by advection, ... Read more
Marine productivity response to Heinrich events: a model-data comparison

Author: Mariotti, V ; Bopp, L ; Tagliabue, A ; Kageyama, M ; Swingedouw, D Date: Oct 2012 Marine sediments records suggest large changes in marine productivity during glacial periods, with abrupt variations especially during the Heinrich events. Here, we study the response of marine biogeochemistry to such an event by using a ... Read more
Multidecadal trend of increasing iron stress in Southern Ocean phytoplankton

Author: Ryan-Keogh, Thomas J ; Thomalla, Sandy J ; Scheel Monteiro, Pedro M ; Tagliabue, A Date: Feb 2023 Southern Ocean primary productivity is principally controlled by adjustments in light and iron limitation, but the spatial and temporal determinants of iron availability, accessibility, and demand are poorly constrained, which hinders accurate ...

The sensitivity of primary productivity to intra-seasonal mixed layer variability in the sub-Antarctic Zone of the Atlantic Ocean

Author: Joubert, WR ; Swart, S ; Tagliabue, A ; Thomalla, Sandy J ; Monteiro, Pedro MS Date: Mar 2014 The seasonal cycle of primary productivity is impacted by seasonal and intra-seasonal dynamics of the mixed layer through the changing balance between mixing and buoyancy forcing, which regulates nutrient supply and light availability. Of ... Read more
Slow-spreading submarine ridges in the South Atlantic as a significant oceanic iron source

Author: Saito, MA ; Noble, AE ; Tagliabue, A ; Goepfert, TJ ; Lamborg, CH ; Jenkins, WJ Date: Sep 2013 Low levels of the micronutrient iron limit primary production and nitrogen fixation in large areas of the global ocean. The location and magnitude of oceanic iron sources remain uncertain, however, owing to a scarcity of data, particularly ... Read more
Surface water iron supplies in the Southern Ocean sustained by deep winter mixing

Author: Tagliabue, A ; Sallée, J-P ; Bowie, AR ; Lévy, M ; Swart, S ; Boyd, PW Date: Apr 2014 Low levels of iron limit primary productivity across much of the Southern Ocean. At the basin scale, most dissolved iron is supplied to surfacewaters from subsurface reservoirs, because land inputs are spatially limited. Deep mixing in winter ... Read more
