From a NOAA Press release:
NOAA-trained team hopeful strategic cut freed an entangled humpback near Tracy Arm
NOAA Fisheries marine mammal entanglement experts are hopeful that a humpback whale is free, after a successful operation to cut the anchor line it was stuck in Sunday afternoon near the mouth of Tracy Arm.
The humpback had become entangled in the anchor line of the cruise vessel Wilderness Explorer early Sunday morning.
During the night, numerous humpback whales had been bubble-net feeding in the vicinity of the vessel, anchored in Holkham Bay near Wood Spit. One of these animals struck the vessel at 2:15 a.m. and became entangled in the anchor line. According to the bridge team, the chain was wrapped around a pectoral fin, and as the whale turned, became wrapped around the head and jaw.
