Cyclic steps in submarine channels on Earth as analogs for bedforms on Martian deltas. a Large-scale net-depositional cyclic steps on the outer levee of the Shepard Meander dissected by a linear train of net-erosional cyclic steps in the Monterey East Channel, California, USA (image courtesy A. Fildani; high vertical exaggeration is to enhance bedforms); b A series of cyclic steps along the thalweg of the San Mateo Channel, California, USA (modified from Covault et al. 2014)
