Lagrangian methods for understanding ocean circulation and tracer transport
Session ID#: 84756
Session Description:
Lagrangian analysis, both from drifting instruments and ocean models, provides a complementary view to the Eulerian view of the ocean circulation and tracer dispersion. In recent years, the development of both online and offline, user-friendly and customizable Lagrangian tools applied to ocean circulation models has led to a greater understanding of ocean processes. In this session, we welcome contributions developing and applying Lagrangian methods to understand the past, present and future ocean circulation from all oceanic regions. Examples of applications include ventilation and subduction processes, water mass pathways and timescales, and transport of physical and biogeochemical tracers by ocean circulation and mixing processes. Both contributions presenting scientific results and advancements in Lagrangian analysis methods from observations and modelling are encouraged.
