The search for a man went missing with his dog near Hove has been scaled down, Sussex Police said.
Gareth Jones, 69, was last seen on Saturday at about 13:00 GMT at Basin Road South in Southwick.
He is believed to be with his brown cockapoo dog, thought to be wearing a red harness, Sussex Police said.
Police said CCTV footage from the area where Mr Jones was last seen appears to show him and his dog being swept out to sea.
Mr Jones's daughter, Rhian Jones, thanked all those who had been searching for her father, and supporting their family, in a social media post.
A coastguard helicopter and two RNLI lifeboats began a search just before midnight on Saturday and resumed on Sunday morning.
"Coastguard and lifeboat crews have now been stood down from the search, but police officers and volunteers are continuing to search the coastline," police said.
