- Offline particle (larvae) tracking and statistics were conducted using a customized version of the open source modeling tool ICHTHYOP (Lett et al. 2008) (http://www.ichthyop.org/) on the hydrographic fields produced by the HYCOM model described above.
- We used a reflective boundary condition at the coast and applied a filter to remove particles that stopped moving for more than 1.5 consecutive days, which were considered beached.
- This filter ensured that larval transport had occurred before tallying onshore recruitment. To establish the appropriate number of particles to be released, we performed repeated trials increasing release numbers (1,000, 5,000, 10,000, 15,000, 20,000, 50,000 and 100,000) and looked for the point at which these statistics stabilized (Brickman & Smith 2002).
