  • Mean Sediment Residence Time in Barchan Dunes

    Mean Sediment Residence Time in Barchan Dunes

    Decomposition of sediment fluxes on a barchan in a quasi-stationary equilibrium state: (a, b) diffusion, (c) bedload transport and (e-g) avalanches. Orientation and intensity of the (d) total and (h) dispersive sediment fluxes on a barchan in a quasi-stationary equilibrium state. If all the transitions are taken into account for the total flux, only the transitions associated with diffusion (a,b) and avalanching (e-g) contribute to the dispersive flux. Integrated longitudinally over the entire dune, the total dispersive flux on the barchan is shown as a vertical inset on the right of (h).

    Sub-panels of Model Inputs and Steady-state Field of Basal Melt/accretion Rates for the Larsen C Ice Shelf

    (a) Subpanels of model inputs including ice thickness [Griggs and Bamber, ], ice velocity [Rignot et al., ], surface mass balance [Lenaerts et al., ], and firn air content [Holland et al., ]. (b) Steady state field of basal melt/accretion rates for the Larsen C Ice Shelf. Basal melting is positive and basal accretion is negative. The flowline cross sections shown in Figure  are indicated by black lines. Mass is reported as meters of water equivalent [1000 kg m−3]. Black star indicates location of observed melt rate [Nicholls et al., ].
