PORT ANGELES — A Port Angeles diver died after his air umbilical cord apparently became entangled while he was geoduck harvesting.

35-year-old Anthony Gockerell was pronounced dead Wednesday morning at Olympic Medical Center. Clallam County Sheriff’s Sgt. John Keegan says a 911 call about a commercial diver in distress at about 8:30 a.m. Gockerell was diving at the Dungeness West geoduck tract about 6.5 miles east of the US Coast Guard Station in Port Angeles.

Crew members said Gockerell’s surface-supplied air cord was entangled in debris and that they pulled Gockerell aboard after a struggle. Keegan says CPR was performed as Gockerell was brought to the hospital but efforts to revive him were unsuccessful.
