Pax reported a change in engine tone before impact with the sea wall, I wonder whether that was an Autothrottle wakeup or a attempt to go around. Looking at the FDR speeds with a vref of 137 the Autothrottle should have come out of hold (if for some reason it was there) and automatically applied thrust at 122kts. I think the EICAS AIRSPEED LOW would have been less than this; 1/2 way between Min Manouver and Stick Shaker.
