Three shipping containers washed up at Seaford in East Sussex on Tuesday.
A spokesperson for the HM Coastguard said a container off Littlehampton, West Sussex, was also recovered, along with debris off Beachy Head.
“An aircraft was sent to survey the area on Friday and no further containers were spotted offshore,” they added.
They said containers which washed up at Selsey, Eastbourne, Newhaven, Rustington, Rottingdean and Beachy Head are being monitored.
They came ashore a month after 16 containers fell from the cargo vessel Baltic Klipper near the Isle of Wight and days after several containers fell from two more ships off the island during Storm Goretti.
