“…Erosional processes can scour channels through the mats, resulting in the formation of 1-3 m high and up to 500 m long escarpments (Serrano et al, 2016; Figure 1). Previous studies also reported the presence of blowouts in Thalassia testudinum meadows, consisting of bare areas with an eroding edge that forms a vertical wall with overhanging seagrass roots and rhizomes (Patriquin, 1975;Wanless, 1981;Maciá and Robinson, 2005). The mechanisms behind escarpment formation can be related to natural processes (e.g., wave action, tidal flow, and hurricanes) or to anthropogenic activities, such as dredging, vessel groundings, and propeller scars (Whitfield et al, 2002).…”
