The bodies have yet to be identified but authorities suspect that many of them are students from Danwon High School in Ansan, Gyeonggi Province.
The rescue workers at the scene, some 20 kilometers off the coast of Jindo Island, South Jeolla Province, are continuing their search.
According to the central response team, the divers secured a route into the ship’s dining area at about 6 a.m. and they attempted to access the area starting around noon.
The authorities deployed 214 ships and 32 aircraft to continue the search, and send in several teams of divers simultaneously to comb through the third and fourth decks of the ship.
In addition, remotely-operated vehicles are to be sent into the ship.
The weather, which has hampered efforts, is set to subside with waves of 0.5 meters and wind speed of between 5 meters and 8 meters per second expected in the area.
The search operations that continued throughout Sunday night had little results.
The Coast Guard said that 214 ships and 35 aircrafts were deployed from Sunday night into the early hours of Monday to conduct searches over the waters surrounding the sunken ferry. In addition, 151 civilian and military divers conducted underwater searches.
However, no signs of survivors have been detected.
