On July 1, 2026, Jiao Kaihong, a master graduated from IMAS, the University of Tasmania, gave a talk at the College of Marine and Atmospheric Sciences on grounded icebergs around Antarctica. Using ResUNet and Sentinel-1 SAR, he constructed a high-resolution dataset of nearly 40,000 grounded icebergs. Small icebergs (<1 km²) account for over 92% of the count and 54% of the total area. Their high perimeter-to-area ratio may enhance coastal friction and affect landfast ice stability and nutrient release. The study also analyzed the Totten Glacier region's trends and iceberg rotation. The dataset provides geometric data useful for ice stability modeling, nutrient flux assessment, and benthic habitat mapping.
