Examining fish movement in terms of advection or diffusion: a case study of northeastern Atlantic cod
Advection (directional movement) and diffusion (dispersed movement) were applied for the first time to describe movement patterns in Atlantic cod in the North Sea and Baltic Sea between 1955 and 2020. The advection−diffusion approach provided more detailed estimates of movement that corresponded to...
