We infer seafloor topography of the inner continental shelf of northeast Greenland from airborne gravity disturbance measured by National Aeronautics and Space Administration's Oceans Melting Greenland (OMG) mission through a nonlinear inversion method called simulated annealing, and results in a model with 1.95~3.9 km resolution and 52 m accuracy. The model provides a view of the seafloor near Zachariæ Isstrøm glacier, where bathymetric survey tracks are sparse. The model, 'gravity_estimated_seafloor_topography_of_northeast_Greenland.nc', is in NetCDF format which can be read through MATLAB commands "ncdisp" and "ncread". Contents of the model can be found in "contents.txt". "nc2mat.m" is a MATLAB program that reads the NetCDF format model and saves the variables to a MATLAB ".mat" format file.
