[vc_row][vc_column][vc_column_text]Bridges – Bridge geomorphic features were first described by Gardner and Armstrong (2011) as blocks of material that partially infill the Mariana Trench in four locations, forming a “bridge” across the trench.  In this study we have extended Gardner and Armstrong’s (2011) interpretation and applied it to all troughs and trenches and have identified a number of bridge features that appear to partially infill trenches and troughs in the global ocean.  Slumping on the sides of some troughs and trenches has formed a bridge across the trench/trough, thereby dividing it into two separate sections
