The boat can carry a lot of people and this day there were about 60 other whale seekers on board. Long story short....everyone wanted to be on the upper deck. When we got near the whale sanctuary and the boat idled and the upper portion of the boat swung violently from side to side, half of the passengers up there fled below to, um, dispose of their lunch. I was thisclose to joining them, when a male whale... literally out of the blue... leaped up, breaching almost completely out of the water! Wow! (times ten) 80, 000 + pounds just lunged straight up out of the sea. I couldn't believe my eyes. No one is quite sure why the whales breach, throwing their entire bodies straight up out of the water. It's not a form of "flirting" most agree and some scientists speculate that it may be just a way to clean their bodies. My theory is they do it because it's just plain F-U-N!

It's a topsy turvy whale world out there. This is the guy that just breached and crashed back into the water... upside down. See his large pectoral fins pointing skyward?
Today I saw a mother and calf and a ginormous male breaching, so I am content. All the regulations and short amount of time a boat can stay near the whales was a little detrimental to us whale watchers, but the safety of the whales and their protection is what it's all about. They help to insure that future whale watching enthusiasts will enjoy the experience for years to come...just as I did today.
But what about the noise from the cruise ships? All these rules for smaller boats, but cruise ships are allowed to get pretty close to the sanctuary. Look at the comparison of the tiny boat on the left with the big ship in the picture below...Did the three enormous ships in the bay have an effect on the activity of the whales that day?
The locals say yes. Nicole Koehler agrees. In a lecture presented to the University Alaska Fairbanks: (Which you can read in it's entirety at http://www.seaweed.org/ )
fishing gear, collisions with ships and disturbance from underwater sound (Richardson et al. 1995). Humpback whales rely on vocalizations (songs) and other sound generation (e.g., flipper and fluke slapping) for communication with each other...(Sharpe 2001) and apparently sensing their environment through echo-ranging (Clark and Ellison 2002). Man-made underwater sound, such as vessel noise, can affect whales in three ways: blocking basic communication and environmental cues, affecting behavior by interrupting activities and/or displacing whales, and temporarily or permanently reducing hearing sensitivity (Richardson et al. 1995). Thus, the potential impact of vessel sound is a concern...(In Baja California, gray whales abandoned a calving lagoon for several years and returned after vessel traffic had diminished (Bryant 1984)."
Cruise ship directors will tell you the ships have little effect on the marine environment. It may come as a surprise from my previous posts, ahem, but... I'm not a big fan of cruise ships. Just think of the pollutants alone that are dumped into the water just from the bath water of thousands of antibacterial, shower gelled, perfumed scented, soaped up people...and then there's the dish water....let alone how their constantly running motors disturb the marine life. Nope I don't like them. But that's just my opinion.
I did see whales and am not disappointed, but I have to admit not many were participating in the frolicking pheromone induced play I had anticipated and read about. But then there's never a guarantee when you're dealing with wildlife. If you are in the area and have a few days to spend, postpone a trip you may have planned if you see the cruise ships in the bay. I think you'll have a better chance of seeing the big show if you wait a day. Those ships don't hang around in one place for long. (If it's Tuesday, this must be Belgium.)
