Dear Authors.
Thank-you for your revised manuscript responding to the reviewers. I am asking for some “technical corrections” – see below – after which you should submit the revised manuscript directly into the Copernicus / OS publishing process. It will be copy-edited and I expect there will be changes; you should check that the final version has the meaning that you want. Thank-you for publishing in Ocean Science.

In response to Reviewer 1 you say “We recognized that exploring if longer PLD would induce significant changes in the trajectories is interesting and it introduces an analyze on the temporal dimension. We dealt with this idea in the context of another study (in preparation) implying the same species, the considered model (ROMS-Rutgers) and different objectives.” Something about this should be in the Discussion – please be careful with the English as I will not be checking for clear meaning.

Detailed comments (mostly for use of English).
Please move equation numbers to the right (separated from the equation itself).
Line 26. Better “bottom, should give more accurate simulations of near-bottom passive drift. Those results . .”
Lines 27, 81, 405, 455. “parameterization” or “discretization”?

Line 37. “consist of” -> “provide”?

Lines 278-279. Do you mean “The drifts within BC were downward by 62 m (average?) when particles were above the northern wall and upward by 36 m (average?) when particles were above the southern wall.”?

Short summary

Deep-sea connectivity research is scarce but needed for understanding marine population dynamics and dispersal of animal early-life stages. Here, we modeled near-bottom particle drifts along a continental margin crossed by submarine canyons. The bottom current impacting particle drifts is influenced by uneven topographic structures like submarine canyons. Thus, models with a good representation of the bottom geomorphological structures contribute to improving the deep-sea larval drift modeling.
