B09B is currently the second largest iceberg identified by the National Ice Center, a joint NOAA, US Navy, and US Coast Guard operation that tracks ice in the Arctic and Antarctic. This iceberg has actually been slowly migrating around the coast for two decades, and along its way changing its size with the seasons and as it impacts other icebergs. This image also illustrates the true nature of sea ice, which can be seen as fragments of ice and other icebergs nearby. In addition, it is also apparent in this image just how dark the ocean appears from space, especially in contrast to the stark white snow and ice. Because of this dark color, the ocean acts as a black body, quickly absorbing heat energy from the sun. As the water heats, energy is transferred to the ice (causing melting) and the air (causing warming
