Pictures of the area where the bones of Angela Millington were found have been released by police.
The remains of 33-year-old woman from Southend was found washed up on Foulness Island on Saturday, June 21 – it is not yet known how or when she died.
Some bones were discovered by a group of ramblers in a salt marsh area as they walked on the island who called the police shortly after 1.45pm.
A full search of the island took place and further skeletal bones were located before extensive forensic tests were carried out to identify the body.
DCI Simon Werrett, of the Kent and Essex Serious Crime Directorate, said: "Angela's remains were found on a part of Foulness Island known as New Burwood Head on the Broomway Path, which is near the Great Wakering Stairs area.
"We believe she may have ended up there by being carried on the tide as it would be very difficult for somebody to take her there."
He added: "Angela led what I would describe as 'chaotic lifestyle'. She had no fixed address and would sometimes go for periods without making contact with her family.
"The last time someone spoke to her was when she visited a Southend housing officer on November 21 2013. I would urge anyone who knew her to come forward with information."
Anybody with any information is asked to contact the dedicated incident room on 01702 470173 during office hours or 101 outside of those times.
Details of the appeal will be circulated on the Essex Police website and social media outlets using the #answers4angela
The appeal also includes a short film which has been made available on the Essex Police YouTube channel.
