Bathymetry beneath the Amery ice shelf, East Antarctica, revealed by airborne gravity

<p>We estimated the seafloor topography beneath the Amery Ice Shelf, East Antarctica, from airborne gravity anomaly through a nonlinear inversion method called simulated annealing. The estimation results provide a view of the seafloor beneath the Amery Ice Shelf, where direct bathymetric observations are rare. The model, &#39;gravity_estimated_seafloor_topography_beneath_the_Amery_Ice_Shelf.nc&#39;, is in NetCDF format which can be read through MATLAB commands &quot;ncdisp&quot; and &quot;ncread&quot;. Contents of the model can be found in &quot;contents.txt&quot;. The&nbsp;MATLAB program &quot;nc2mat.m&quot;&nbsp;reads the NetCDF &quot;.nc&quot; format model and saves the variables in the model to a MATLAB &quot;.mat&quot; format file.</p>
