The calving of an iceberg from the Larsen C ice shelf is a natural occurrence, though the large size of this particular iceberg is unusual. In continuation of this process, the iceberg will be caught up in local currents and eventually drifts out of the region.  Its gradual disintegration will change the ecological composition of adjacent waters. Ocean surfaces left in perpetual darkness when the ice shelf was intact will now be exposed to the atmosphere and sunlight. Photosynthesis will take place and biological activity will occur in areas where once there was none or very little. Icebergs laden with dust and sediments that they trapped when ice formed on land will seed new areas of the Weddell Sea and beyond with iron, nitrates, and other nutrients that will encourage primary productivity at the base of the ocean food web. For marine biologists and biological oceanographers, this is an important opportunity to understand the evolution of ecological systems that may accompany future trends in climate.

About Scripps OceanographyScripps Institution of Oceanography at the University of California San Diego, is one of the oldest, largest, and most important centers for global science research and education in the world. Now in its second century of discovery, the scientific scope of the institution has grown to include biological, physical, chemical, geological, geophysical, and atmospheric studies of the earth as a system. Hundreds of research programs covering a wide range of scientific areas are under way today on every continent and in every ocean. The institution has a staff of more than 1,400 and annual expenditures of approximately $195 million from federal, state, and private sources. Scripps operates oceanographic research vessels recognized worldwide for their outstanding capabilities. Equipped with innovative instruments for ocean exploration, these ships constitute mobile laboratories and observatories that serve students and researchers from institutions throughout the world. Birch Aquarium at Scripps serves as the interpretive center of the institution and showcases Scripps research and a diverse array of marine life through exhibits and programming for more than 430,000 visitors each year.
