The principal objective of this paper is to describe the most well-known and widely used algorithms of mesoscale eddies detection and tracking in the World Ocean. Considered algorithms are classified into types (physical, geometric, mixed) and then discussed in chronological order. The basic principles of these algorithms, the data required, and the main advantages and disadvantages are analyzed. In addition, efficiency parameters are given for some of the algorithms. Improvements in the detection and tracking algorithms led to a significant progress in the understanding of the distribution and dynamics of mesoscale eddies in the World Ocean. It is also shown, that a variety of methods used in the algorithms enables a rational choice of a particular algorithm based on the scientific goals and available resources. The factors constraining the development of algorithms and their implementation in research practice are also described. The prospects and ways of development of these algorithms are highlighted. The paper also briefly discusses open access datasets, created by means of the detection and tracking algorithms; these datasets contain information about the distribution of mesoscale eddies in the World Ocean.
Keywords: mesoscale eddies, algorithms, detection and tracking, remote sensing
