October 18, 2023 - East Antarctica - A wide view of a subset of the icebergs trapped in fast ice that day east of the West Ice Shelf (not pictured). The dark, linear areas on the lee side of the bergs are where wind has blown away the snow to expose bare ice below a process called wind scouring. Jan Lieser has analyzed countless satellite images of frozen seawater clinging to the coast of East Antarctica. This ice known as landfast ice or simply fast ice regulates the seaward flow of land ice and provides habitat for animals. The ice's textures can be varied, but its colors are mostly grayscale. In October 2023, something green caught his eye. That outlier iceberg is visible captured by the OLI-2 Operational Land Imager-2 on Landsat 9. (Credit Image: © NASA Earth/ZUMA Press Wire)
