PCCS saves another Humpback Whale

Using pole and hook-shaped knife to cut the entanglement below the waterline, rescuers from the Provincetown Center for Coastal Studies managed to save another Humpback Whale north of Cape Cod last Sunday.

Humpback whale, Sockeye, disentangled on Stellwagen Bank

Sockeye, an adult male humpback whale, was disentangled by the Provincetown Center for Coastal Studies (PCCS) disentanglement team on Sunday, July 9, 2006. The successful disentanglement was made possible in collaboration with local whale watch companies, NOAA Fisheries and the Stellwagen Bank National Marine Sanctuary (SBNMS).

Late on Sunday morning whale watch crews from the Hyannis Whale Watcher Cruises sighted a humpback whale swimming on Stellwagen Bank (the shallow waters between Gloucester and Provincetown in Cape Cod Bay) with bright red netting and green rope streaming from his mouth.

Sockeye is a well-known humpback whale, easily identified by a severe underbite as he surfaces to breath. This deformity was noted when he was first seen in 1984.

After reporting the sighting to PCCS the whale watch boats from the Hyannis Whale Watcher Cruises, Portuguese Princess and Dolphin Fleet offered to stand by the whale as he traveled with two other whales, including Putter, another humpback disentangled by PCCS in 1998. Without this stand by effort it is very likely that Sockeye would have been lost.

By midday SBNMS researchers aboard the NOAA Fisheries research vessel Nancy Foster relieved the whale watch boats as the disentanglement team aboard the small inflatable Ibis made their way to the whale.

The crew of the Nancy Foster was conducting behavioral research on humpback whales and was ideally suited to standing by and documenting the freeing of the entangled animal.

The whale Sockeye had a long length of line and netting attached at the tip of the mouth and trailing to two wraps at the flukes. The team noted that the monofilament webbing was fouled on the raised tubercles (enlarged hair follicles) of the chin.

The PCCS disentanglement team was joined by a scientist from the Hawaiian Islands Humpback Whale National Marine Sanctuary, and once on scene, the team deployed a small inflatable boat for the disentanglement attempt.

Using a grappling hook, the team attached a long length of rope to the entanglement on the whale. Using the drag of buoys and the work vessel, the whale was slowed and kept at the surface. Using a long pole and hook-shaped knife, the team cut the rope wrapped around the flukes and slowly pulled the remaining gear from the mouth.

The successful outcome of this disentanglement would not have been possible without the collaborative effort between PCCS, whale watch companies, NOAA Fisheries, SBNMS and other research institutions. PCCS would like to thank the Hyannis Whale Watcher Cruises, Portuguese Princess Excursions, and the Dolphin Fleet. Special thanks goes to the crew of the Nancy Foster.
