A cyclonic circulation gyre or eddy sometimes found to the east of Mindanao centred at about 8° N and 135° E. The southward flowing section near the coast is part of the Mindanao Current, and the Eddy can be thought of as the recirculation cell of this current. The southward flow does not extend beyond a depth of 250 m and is underlain by a deep western boundary current flowing northward (from about 250 to 500 m) at a rate of 16-18 Sv. The transport has been estimated at around 25-35 Sv with strong interannual variations. At least one investigation of the Mindanao Current at 8 ° N noted the absence of the Eddy, and as such it may be an intermittent feature of the circulation field. This has also been called the Mindanao Dome.
