A sea mine has been safely removed from the Gourock coast.
Those who were evacuated from their properties in the area have been allowed to return.
Explosives experts confirmed the location of the device off the coast of the Inverclyde town, near a swimming pool, on Monday.
The unexploded ordnance device is thought to be a sea mine dating from either the 1940s or 1950s.
A number of residents living within 200 metres were moved out earlier on Thursday.
Police also issued safety advice to residents who live within 500 metres and an exclusion zone at sea of around 1,000 metres was set up.
The Royal Navy said they would continue to work in the water until later in the afternoon, and the exclusion zone was expected to remain in place during this time.
Ferries were expected to return to normal shortly. Small boat owners were asked to refrain from sailing, and await further updates from the Coastguard and other agencies.
