  abstract = {{I}n {F}ebruary 2010, the {M}ertz {G}lacier {T}ongue ({MGT}) calved, releasing an 80 x 40 km iceberg. {W}e have developed a high-resolution barotropic ocean model of the region to simulate the local circulation in response to tides and atmospheric forcing. {W}e improved the coastline, grounding line position and built a new bathymetry using satellite imagery and older bathymetry data to derive the best available tidal model for the region. {W}e compared this and other available models to seven different sea level observations available in the area and significantly improved the tidal solutions reaching a root sum square of 2.3 cm. {T}his model was then run in different bathymetric configurations, considering the ice draft of the major icebergs {B}9{B} and {C}28, to simulate the circulation before, during, and after the calving event. {T}he currents changed substantially in the neighborhood of the {MGT} and icebergs. {T}he barotropic model with tidal and atmospheric forcing and the atmospheric wind fields allow us to evaluate the forces acting on the {MGT}. {T}he sea surface slope force dominates the budget. {C}alving occurred when high tide and strong nontidal currents (due to atmospheric forcing) combined to lead to the monthly maximum forces exerted on the {MGT} (i.e., between 10 and 13 {F}ebruary 2010). {W}hile the forces are not unusually large at the calving time, the currents are largely enhanced in the rifting area. {T}herefore, processes related to these currents, like melting the ice melange inside the rifts, should be investigated to fully explain the final stage of the calving.},
