PL34B:
Multiscale Variability of Boundary Currents and Their Role in Climate and Ecosystems I Posters


Session ID#: 29753

Session Description:
The global oceanic basins feature energetic boundary currents (BCs) that redistribute water, heat and salt, and exhibit a complex web of physical and biogeochemical processes along their paths. As such, BCs play a major role in regulating the global climate system. Yet monitoring the multi-space and time scales of the energetic dynamic flows of boundary currents can be complicated. These boundary currents tend to act as barriers to cross-front flow, but variability associated with multiple types of instabilities, and on a range of time and space scales, act to facilitate cross-front flow, stirring, and mixing along their paths, further complicating the study of these currents. This session seeks contributions from studies including, but not limited to, the full multi-scale variability of BCs from time and space scales that span subseasonal to multi-decadal and from turbulent to basin scales; their interaction with marginal seas, frontal processes and air-sea interaction; and their impacts on marine ecosystems. In addition, we welcome papers that discuss observational (in situ and remote), analysis, theoretical and model simulations that emphasize achievements in sustained BC monitoring, and so provide guidance for the development of a future effective and efficient monitoring network.
