Despite numerous surface eddies are observed in the ocean, deep eddies (a type of
eddies which have no footprints at the sea surface) are much less reported in the
literature due to the scarcity of their observation. In this letter, from
recently collected current and temperature data by mooring arrays, a deep
energetic and baroclinic eddy is detected in the northwestern South China Sea
(SCS) with its intensity, size, polarity and structure being characterized. It
remarkably deepens isotherm at deep layers by the amplitude of ~120?m and induces
a maximal velocity amplitude about 0.18?m/s, which is far larger than the median
velocity (0.02?m/s). The deep eddy is generated in a wake when a steering flow in
the upper layer passes a seamount, induced by a surface cyclonic eddy. More
observations suggest that the deep eddy should not be an episode in the area.
Deep eddies significantly increase the velocity intensity and enhance the mixing
in the deep ocean, also have potential implication for deep-sea sediments
transport.
