Friday the 13th - lucky day for entangled humpback in MOnterey bay
It was a multi-day, community effort that ended in a humpback whale swimming free after it was successfully disentangled in Monterey Bay on Friday, December the 13th. Responders from the West Coast Large Whale Entanglement Response Network, including Marine Life Studies’ Whale Entanglement Team (WET)®, Cascadia Research, SR3 Sealife Response Rehab and Research, and The Marine Mammal Center Monterey Bay Operations (TMMC-MBO) staff, successfully removed all the fishing gear that was wrapped around the body of the young whale as seen in photos below.
The whale was first reported by a fisherman on December 9th and the US Coast Guard (USCG) vessel, Pike, responded to and stood by but due to the whale's unpredictable behavior they had not seen it after the whale dove just as the response team arrived. The USCG along with the response team aboard Current'Sea, Marine Life Studies' Whale Rescue Research Vessel, which included members of our Whale Entanglement Team (WET)® and our partners Cascadia Research, SR3 Sealife Response Rehab and Research, and TMMC-MBO searched until dark.
The following day, December 10th, the whale was spotted by Sea Spirit Ocean Safari, but unfortunately it was too late in the day to mount a response.
On December 11th, a multi-agency search of Monterey Bay was conducted that included: USCG aircraft, the USCG vessel Pike, WET® vessel Current'Sea, the MBNMS vessel R4107, and Cascadia/SR3/TMMC team aboard vessel Musculus. Although the search turned up over 40 humpback whales, the entangled whale was not relocated.

WET's vessel Current'Sea, searched while operating on only one engine since one of the injectors on the starboard engine broke after the search on Monday, December 9th. Jay Salinas from Peninsula Diesel in Moss Landing, one of our partners, came to the rescue the next day and quickly installed a new injector. Although Peninsula Diesel was very busy, they made it a priority to help us, as they knew we had to be up and running due to the entangled whale. Again, everyone in the community contributes to our efforts.

On Friday the 13th, we left Moss Landing early to search for the entangled whale again during our Research Scientist Program, with trained WET® members aboard. While surveying and checking each humpback we came across, one of our other partners, Monte Ash with TowBoatUS Santa Cruz, spotted the entangled whale as he was towing a disabled boat to Moss Landing. Monte reported it to the hotline but also called us on the VHF radio with the coordinates. We were very close to that area and arrived within 15 minutes and located the entangled whale dragging buoys. We started the assessment process by recording the whale’s respirations and behavior while we waited for our network responders from SR3, Cascadia, and TMMC-MBO to come out in the TMMC-MBO vessel, Ever Lucan. By the time they arrived, we had a lot of valuable information; as we kept track of each dive sequence which included how long the animal remained on the surface, the number of breaths the whale took, when it dove, and how long the line with the buoys were at the surface after the whale dove. We also recorded a series of dive times so it gave us an idea when the whale would come up again. Recording the behavior of the whale from a respectable distance gave us a baseline to determine if the whale was calm or stressed on our initial arrival. This is important to know, because during a rescue, you can see if there were any changes in behavior that might give you a sign if the whale is stressed or agitated during the rescue process. We documented the entanglement with still and video cameras, trying to understand the complexity of the entanglement, meanwhile taking identification photos of its dorsal fin and tail flukes. The whale was very mobile and moved very quickly around the north side of Monterey Bay, approximately 7 to 9 miles WNW of Moss Landing.
Once the rest of the response team arrived, we deployed our new WING, an inflatable boat designed specifically for whale disentanglement, thanks to our generous donors. The team approached the whale and attached A4 and A5 polyballs one at a time (a total of 5) to slow the down the fast moving whale and to keep the whale from diving, keeping it on the surface. They do this to work up and along the existing trailing gear to do the close up underwater assessment with a GoPro (underwater camera) on a long pole. Once that was complete, they returned to Current'Sea to review the footage on the computer and planned where the best cut would be to remove the entire entanglement. The response team determined the configuration was life threatening and the constricting wrap would cut into the whale’s body as it continued to grow. The response team returned to the whale with a fixed pole knife and a 30-foot carbon fiber pole.

They picked up the working line and pulled the engine up on the WING and worked their way back up to just behind the flukes while being pulled behind the whale, getting what we call the "Nantucket Sleigh Ride". They were able to make one single cut to the line running across the whale’s back. The whale reacted vigorously by slapping its flukes at the surface as all the gear quickly fell away. It took a few minutes for the whale to realize it was no longer entangled, but then it swam away as a free whale.

Entangled whales can be dangerous and should be approached only by trained response teams authorized by NOAA Fisheries. Entanglement Response Network partners receive training from NOAA Fisheries and invest much of their own time in training for and responding to entanglements. We are grateful for all of our entanglement response partners along the West Coast.
Prompt reporting is the best way to help an entangled whale. Report entangled whales on the West Coast to the 24/7 hotline by calling (877) SOS-WHALe / (877) 767-9425 or hailing the U.S. Coast Guard on VHF Channel 16.
Many thanks to the USCG for their outstanding support conducting the search and the reporting parties who reported and documented the entanglement. The response was a success because of the support from so many members of the community and highlights the importance of standing by an entangled whale while calling 1-877-SOS-WHALe (1-877- 767-9245) or hail the United States Coast Guard on VHF CH-16.

How you can help if you see an entangled whale:
Report immediately, call 877-SOS-WHALE (877-767-9425) or hail the U.S. Coast Guard on VHF CH-16.
If possible, please stay with the animal while maintaining 100 yards distance from the animal. Authorized personnel will guide you as what to do next.

- Note the nature of the entanglement, location of the entanglement on the whale's body (i.e. a blue line wrapped around the tail (fluke) and wrapped around body by dorsal fin, description of the gear trailing (i.e. buoys if any and the number and color of the buoys, line or other gear trailing with approximate distance behind the whale the gear is trailing).
- Relay the whale's exact location (be as specific as possible, include latitude and longitude if available). Did you know you can get your exact location with your smart phone. Click to learn how.
- Other details such as is the animal swimming (speed and direction the animal is heading, is it diving or staying on the surface, is it breathing). One of the important keys to the success of freeing a whale from a life-threatening entanglement is to have someone standing by until one of our Whale Entanglement Team members arrives.
- If you are able, while maintaining 100 yards from the whale, please take high-resolution photographs of the whale including: the right and left side of the animal including the dorsal fin, the head and back on both sides, the area between the dorsal fin and the fluke (tail), the underside of the fluke if the animal is diving (if it dives it will raise its fluke vertically above the water and the underside of that fluke is a unique pattern that we can identify individual animals, like a human fingerprint), and any trailing gear or buoys.
