South Korean officials are expected to take over on-scene control of search efforts following the deadly sinking of a fishing vessel in the western Bering Sea last month.

The U.S. Coast Guard has been overseeing the effort. Rear Adm. Dan Abel said with the scheduled arrival of the South Korean vessel Sambong this weekend, the Coast Guard plans to take on a role of search and rescue planning.

Seven people survived the sinking of the Oryong 501, which occurred in Russian waters. Abel said the remains of 27 people have been recovered. Another 26 remain unaccounted for, he said.

The commander of the Coast Guard in Alaska said two South Korean aircraft have been based out of Joint Base Elmendorf-Richardson in Anchorage as part of the response.
