Abstract
We study turbulent oceanic flows in the context of ocean color.
Observations of the submesoscale processes with scales of O(1km)
and O(1day) has been difficult from a satellite because spatial and
temporal sampling frequencies of satellite data do not typically
meet the range of submesoscale oceanic processes. The advent of
geostationary ocean color imager (GOCI) that has high spatiotemporal
resolutions (hourly observation with 500-m ground
sampling distance) enables us to observe scalar and velocity fields
in the submesoscale range near the Korean Peninsula. This
motivates us to use the GOCI to study how submesoscale processes
interact with pseudo-passive tracers such as phytoplankton,
suspended sediment, and floating algae (e.g. Sargassum). The
surface current in the East/Japan sea is derived from the spatial
and temporal changes in chlorophyll-a concentration using the
Particle Image Velocimetry (PIV) method. The procedures that
generate surface velocity field and some applications that utilize the
velocity field for the study of submesoscale turbulence over the
oceanic surface are introduced.
