In ocean search and rescue missions, how to efficiently locate missing submersibles is a challenging problem. The distribution of submersibles may remain relatively stable in some periods of time, but it may also show dynamic changes due to changes in environmental conditions such as terrain, density of seawater and ocean currents. Affected by factors such as minerals, the density of seawater generally increases linearly with the increase of depth. The partial derivative and gradient differential methods are used to simulate and analyze different terrain when it has great influence on submersible. The speed of ocean currents decreases with depth, and submarine currents are usually slow and steady. Ocean current data set is collected for data preprocessing. A large amount of real data is helpful to determine the direction and speed of ocean currents in each region quantitatively, and then analyze the motion trajectory of submersible, which proves the reliability of theory applied in practice. Considering the uncertainty of submersible position over time, this paper proposes a path planning method combining greedy algorithm and grey wolf optimization (GWO) algorithm together, and discusses the cooperative working mechanism of multiple searchers. The greedy algorithm is used to plan the path of a single search submersible, and the grey wolf optimization algorithm is introduced when considering the joint search of multiple search submersibles. Each step of greedy algorithm is to select the current optimal solution and build the overall path to the local optimal. Through programming, a route with a success rate of about 91% was obtained, and the shortest path was calculated to be about 50,155.69 meters. The GWO is solved by simulating the hunting behavior of wolves, combining the obstacle avoidance strategy of the submersible and the multi-agent cooperative method. When the search success rate remains above 90%, by applying GWO, the search efficiency is improved as the s
