PL53B:
Deep and Abyssal Ocean Circulations in the Pacific: Characterization, Dynamics, and Representation II


Session ID#: 36787

Session Description:
Deep and abyssal ocean circulations play an important role in the global ocean circulation system, the distribution of oxygen and nutrients, and long-term global climate variability. However, measurements in the deep layers are still sparse, and hence there are large gaps in our knowledge of deep and abyssal ocean currents. Studies over a wide range of scopes are thus valuable to expanding our understanding. Such studies include, but are not limited to, (1) revealing the structure, characteristics, and variability of deep and abyssal ocean currents, (2) illustrating the influence and constraint of ocean bottom topography on the deep ocean currents, (3) studying on the Pacific deep western boundary current, rotating hydraulics, and dense overflows, (4) studying the underlying physics of deep ocean circulations which facilitate our modeling of deep ocean as well as our interpretation of observational data, and (5) discussing the influence and response of deep ocean currents to the climate change. There is no clear boundary exist between these topics, instead more interaction between them is more than needed and will certainly be beneficial to all. This session welcomes abstracts on observational, theoretical, laboratory, and modeling studies of processes relevant to the Pacific deep and abyssal ocean circulations.
