Cross Gyre Flow Experiment
Recent studies (one historical observational data analyses research & another numerical simulations research) have suggested that there might be northward transport of warm & saline water from the Subtropical gyre to the Subarctic gyre of the North Pacific at the sea surface & subsurface layers
One of the pathways of the cross gyre flow might be "Isoguchi Jets." Studies suggest that the cross gyre flows would play an important role in determining the overturning circulation in the North Pacific Ocean that connects the surface & the intermediate layers via ventilation in the Sea of Okhotsk. There is however little direct & real time observations to detect these cross gyre flows.
We would like to execute direct observations using Argos sea surface drifter buoys to clarify the existence of the cross gyre pathway.
The observation (Argos drifter buoy deployment) plan is as follows:
