Macroecological Approaches to the Arctic Ocean System: Changes and Implications on Biogeochemical Cycles III Posters
Session ID#: 9492
Session Description:
Macroecology advocates the collection of large amounts of some “easily” measured data at large spatial scales in order to examine relations between organisms and their environment. Focus is given to pattern, scale, regionality and seasonality. In the Arctic Ocean, the most striking physical changes are associated with diminishing sea ice extent and thickness, resulting in a loss of an important interface between the ocean and the atmosphere. Understanding the response of biogeochemical cycles and the marine ecosystems to these changes requires the integration of physical, biological and chemical oceanographic studies across a range of temporal and spatial scales. We encourage submissions ranging from the micron scale (e.g., phytoplankton, ice algae and bacteria) to the km scale (e.g., satellite pixels-from-space; spring and fall blooms) and from turbulent bursting phenomena to decadal and longer time scales. We seek interdisciplinary data and synthesis products that elucidate the current status of the physical (i.e., ocean, sea ice, atmosphere) and biogeochemical processes, how feedbacks and controls could change Arctic marine systems, as well as research on complex systems and thresholds. We especially invite advances linking the hard-to-measure biological distributions to the easier-to-measure physical conditions at large spatial and long temporal scales.
