The February image displays a vast expanse of old sea ice fastened to Land Glacier and the surrounding Antarctic coastline. In the March image, part of the glacier’s tongue (an extension of the landbound glacier that protrudes over the water) and much of the nearby old ice had broken apart and new ice began to form. Surface winds create streaks in some of the new ice, while swirling patterns indicate ice pushed around by winds and eddies. The green-yellow tinge is largely an effect of low light and automatic color corrections. Read more at NASA’s Earth Observatory.
