PROBLEM TO BE SOLVED: To provide a spike noise removing device capable of removing a spike noise of a water temperature or the like in a shallow sea area, and a spike noise removing method using the spike noise removing device. SOLUTION: This device is equipped with a means 101 for storing a water temperature profile in the depth direction of an actual sea area which is a measuring object as water temperature measuring data, a means 102 for storing a water temperature profile in a plurality of depth directions other than the measuring object as a water temperature data set, and an operation means 120. The operation means 120 generates a water temperature data matrix from the water temperature measuring data and the water temperature data set, and, after generating a water temperature data deviation matrix from the water temperature data matrix, calculates an EOF mode and its coefficient by performing EOF development of the water temperature data deviation matrix, and removes the spike noise in the water temperature measuring data by reorganizing the water temperature measuring data by adding the finite number of each product of the EOF mode and its coefficient.
