Summary
New edition of the leading resource on the Arctic and Southern Oceans with contributions from the world's experts on sea ice. Sea Ice delivers insights into the very latest understanding of sea ice dynamics, how we measure (and model) its extent, the ecosystems that depend on sea ice, and the effect of climate change on its distribution. The book also discusses how sea ice influences the oceanography of underlying waters and the influence that sea ice has on the world's climate. This newly revised and updated Fourth Edition looks at ice-based food webs and the impact on global geopolitics as well as changes in human activity in the Arctic. Written by a team of more than 80 of the world's leading experts from 13 countries, Sea Ice includes information on: * Sea ice thickness distribution and snow and surface processes on sea ice; * The short-term and long-term dynamics of Arctic versus Antarctic Sea ice; * Current methods of satellite remote sensing of sea ice; * The ecology of sea ice, from microbes to mammals to marine birds; * The cycling of contaminants across the ocean-sea ice-atmosphere interface. In its new edition, Sea Ice remains the leading multidisciplinary resource on the subject for all policy makers, researchers, and students with an interest in the polar regions and their role in the world's oceanic systems. Chapter 16 - This chapter focuses on sources, sinks, and biogeochemical transformations of biologically important inorganic and organic solutes in sea ice. We describe seasonally changing physical, chemical, and biological processes that influence the pools of dissolved inorganic macronutrients, micronutrients (trace metals), dissolved and particulate organic matter, and exopolymeric substances in sea ice. This chapter focuses on processes occurring in Arctic and Antarctic landfast sea ice and pack ice, while also including a limited number of examples from lower-latitude sea ice. Finally, we provide an outlook on future research needed to understand coupled physical–chemical–biological processes affecting biogeochemical cycling in rapidly changing sea ice–covered environments.
