1999年10月至2002年7月在菲律宾棉兰老岛东海岸附近（6°50′N，126°43′E）进行了系泊观测，以观测棉兰老海流（MC）轴处的海流变化。MC是一股强海流，在大约100 m深度处的地下速度最大值超过1.3 m s-1。MC流浅于700米，并没有证据表明，一个稳定的向北流（棉兰老暗流）在研究地点。与大的平均速度相比，MC的变异性很低（所有方向的标准差<0.2 m s-1）。所有观察到的年际，季节和季节内变化的MC的幅度相当。在北半球夏季和2002-03年厄尔尼诺开始期间，MC很强。在大约100 m处的MC的核心速度与菲律宾的宿务和帕劳的马拉卡勒之间的海平面差相关。
Mooring observations were conducted from October 1999 to July 2002 near the east coast of Mindanao Island, the Philippines, (6°50′N, 126°43′E) to observe current variability at the axis of the Mindanao Current (MC). The MC was a strong current with a subsurface velocity maximum exceeding 1.3 m s−1 at approximately 100 m depth. The MC flows shallower than 700 m, and there was no evidence of a steady northward current (the Mindanao Undercurrent) at the study location. Compared with the large average velocity, MC variability was low (standard deviation <0.2 m s−1 for all directions). All the observed interannual, seasonal, and intraseasonal variations in the MC were of comparable amplitude. The MC was strong during boreal summers and during the onset of the 2002–03 El Niño. The core velocity of the MC at approximately 100 m was correlated with the sea level difference between Cebu, Philippines and Malakal, Palau.
