The flow of warm water toward the western Getz Ice Shelf along Siple Trough, West Antarctica, is intermittently disrupted during short events Winter Water deepening. Here we show, using mooring records, that these 5–10 days-long reduced heat transport ice shelf cavity by 25% in winter 2016. coincide with strong easterly winds and polynya opening region, but deepening controlled non-local coasta...

Oceanic surface gravity waves have a mean Lagrangian motion, the Stokes drift. The dynamics of winddriven, basin-scale oceanic currents in the presence of Stokes drift are modified by the addition of so-called vortex forces and wave-induced material advection, as well by wave-averaged effects in the surface boundary conditions for the dynamic pressure, sea level, and vertical velocity. Some the...

I den här artikeln vill jag undersöka hur Michel Ekman konstruerar speciella tidsrum eller kronotoper inom ramen för Utanför tiden. Självbiografiska essäer. Teoretiskt tar avstamp i Michail Bachtins analys av kronotoper, så som han utformat framför allt sin text ”Kronotopen. Tiden och rummet romanen. Essäer historisk poetik” (som ingår samlingen Det dialogiska ordet, 1991).

Abstract. Bottom pressure observations on both sides of the Atlantic basin, combined with satellite measurements sea level anomalies and wind stress data, are utilized to estimate variations Meridional Overturning Circulation (AMOC) at 11∘ S. Over period 2013–2018, AMOC its components dominated by seasonal variability, peak-to-peak amplitudes 12 Sv for upper-ocean geostrophic transport, 7 Ekman...

Pathways of wind-power input into the ocean general circulation are analyzed using Ekman theory. Direct rates of wind work can be calculated through the wind stress acting on the surface geostrophic flow. However, because that energy is transported laterally in the Ekman layer, the injection into the geostrophic interior is actually controlled by Ekman pumping, with a pattern determined by the ...

Aquarius observations feature a prominent zonal sea-surface salinity (SSS) front that extends across the tropical Pacific between 2–10 N. By linking to Argo subsurface salinity observations and satellitederived surface forcing datasets, the study discovered that the SSS front is not a stand-alone feature; it is in fact the surface manifestation of a low-salinity convergence zone (LSCZ) located ...

Abstract The frequency and latitudinal dependence of the mid-latitude wind-driven meridional overturning circulation (MOC) is studied using theory linear nonlinear applications a quasi-geostrophic numerical model. Wind-forcing varied by either changing strength wind or shifting location stress curl pattern. At forcing periods less than first mode baroclinic Rossby wave basin crossing time scale...
