The Dynamic Coupling among Phytoplankton, Ice, Ice Algae and Krill (PIIAK)
Abstract: This collaborative study between the Desert Research Institute, the University of California, Santa Barbara (0529087; Robin Ross), and the University of California, San Diego (0528728; Maria Vernet) will examine the relationship between sea ice extent along the Antarctic Peninsula and the...
