Reviewer 1 Report
The authors presented is an efficient method to locate and extract of the Iceberg calved areas of the Antarctic Ice Shelves, and the proposed method is applied to the Antarctic coastline, which avoids repetition and omission during the calved area extraction process. This is a nice work and well written manuscript. I believe the manuscript needs some minor revisions before publication. Please find my comments below.
Generally, the ice velocity is not a constant, this may affect the results. If there is an unsteady ice movement, what does the author think about the impact to the results?
Steep terrain will have an impact on ice Calve. Generally speaking, the steeper the slope, the greater the impact will be. Has the author considered this?
What is the error of the Ice velocity from MEaSUREs, and how the error will propagate to the results?

Efficient Location and Extraction of the Iceberg Calved Areas of the Antarctic Ice Shelves
The manuscript to contribute to understanding of the calving events of the Antarctica ice shelves with a novel method for the extraction the calved area using single-phase images.
The introduction provided sufficient background and include all relevant references.
The data were adequately described. The data preprocessing, iceberg calving extraction, and accuracy assessment were adequately described in manuscript.
The results are clearly presented, and the discussion are supported by the results.
Therefore, I recommend that a minor revision. I explain my concerns in more detail below.
-Why is used only 30 calved-area samples?
-The authors compared the simulated coastline with the frontal edges in the corresponding remotely sensed images. Near the position of the grounding line could be higher ice velocity, as Pine Island Glacier, mainly summer mouths. Is there one problem for methodology application and results?
-The figure 2, 3, 7, 8 and 9 are essential in the manuscript, but they need of the coordinating grid information.
-The abstract could be more quantitative (numerical results) and could be included a brief summary of the spatial distribution of iceberg calving in period.
