The ferry was carrying 476 people when it capsized off Jindo Island and 174 passengers were rescued on the day of the accident, including the captain and most of the crew. So far, 188 have been confirmed dead.
On Monday, the Coast Guard said "Some 92 divers are ready to resume the job, but operations underwater are not possible as of now" due to inclement weather causing strong currents.
The search of the five story vessel has been hampered by murky water, strong currents and sealed compartments. There is also concern that the currents may have swept some bodies away.
"Apart from the ongoing efforts including casting nets surrounding the site and operations by trawlers, we are considering diverse measures to prevent bodies from being lost," a Coast Guard official said, adding "We also asked for cooperation from Japan and China."
Cellphone video taken aboard the sinking vessel by a teenage passenger made headlines Monday. The boy, whose cellphone was recovered along with his body and turned over to investigators, included a three-minute audio clip that depicted the confusion as the ferry sank.
"Wow, it's tilting a lot. We're tilting to the side. Can't move."
"You think I'm really gonna die?"
"What's going on?"
South Korean Prime Minister Chung Hong-won, amid increasing controversy over his administration's handling of the Sewol ferry disaster, resigned Sunday. In his resignation statement, he acknowledged "During the search process, the government took inadequate measures and disappointed the public."
An investigation into the cause of the sinking is ongoing. Meanwhile, the ship's captain and crew have been arrested.
