Gray whales were the first great whales to
be removed from the endangered species list, but their future
is by no means certain. They typically spend their summers
feeding in the plankton-rich waters of the Bering and Chuckchi
Seas and winters in the warm lagoons off Baja California,
where their calves are born. But recent evidence suggests
that some of these whales are feeding in the winters and mating
in the fall, challenging the assumptions underlying gray whale
conservation plans. Dr. William Megill, Dr. Lei Lani Stelle,
and colleagues are taking a new look at how much gray whales
are eating at each end of the migration, and what impact varying
prey abundance will have on the whales.
Join us on a journey to Baja California Sur, led by Dr.
William Megill as he takes us down an incredibly bumpy road
toward an Earthwatch site intended to study the behavioral
habits of Grey Whales. This video is meant to give
you an overview of the whales' situation.

The day today was much more humid than the previous days which
made being on the cooler water much more enjoyable.
The team I went out with was Sergio, Bernardo, Francisco,
and Susan. Our group was one of the more important groups
going out on the water because we brought an underwater camera.
The camera, when submerged, would show ...

Gray Whale Migration.
There exist a number of federal and state level laws in
Mexico that protect Grey Whale habitat and establish a regulatory framework
similar to those established in the US. For those familiar with US law, touching
or swimming with whales is prohibited because it is considered harassment (under
the legal definition of "harm"). Under both US and Mexican law there are very
specific rules about where boats can and can't be, how boats can approach whales,
and fishing in the presence of whales or in their habitat. However, unlike US
law, Mexico does not define human-contact as harassment or "harm" as long as
the way in which a human comes within the proximity of a whale is legal.
All tour operators in the Laguna San Ignacio are locals who have received
legal permits for operating their boats in the Lagoon. They have formed a conservation-focused
tourism cooperative through Kuyima, and have developed their own very strict
regulations for approaching whales. The tour operators are very respectful of
the whales and follow the regulations to the letter. Boats may never chase a
whale, and must maintain a designated distance when following a whale for research
purposes.
Laguna San Ignacio is the first place researchers and tour operators ever observed
what is known as "friendly whales". As you see here in these pictures, whales
actually approached the boats. Some will come close and "spy-hop", which means
they stick their head above the water to get a good look at the boat. Others
come right up along side the boat, reaching their noses and lips into the boats
to be scratched. Over time, more whales in this lagoon have adopted "friendly
whale" behaviors, and touching, scratching and even kissing whales in Laguna
San Ignacio is permitted.
