A new high-resolution multibeam bathymetry compilation of the Arctic Ocean-United States Arctic Multibeam Compilation (USAMBC)-was created from data available through public repositories. Much of the new data was collected through dedicated mapping cruises in support of the United States effort to map regions beyond the 200nm Exclusive Economic Zone. Data quality was evaluated using nadir beam crossover error statistics, and compiled into a high-resolution product through a weighted vertical stacking algorithm.
