Before I get to the sharks…er or attempt to work with
sharks…I give you a photo of our alarm clock!
Now…the myth is that roosters wake you up at dawn. Well, here on Moorea they aren’t bothered by
technicalities like daylight…5am and dark is fine for them. And 530.
And 0600, but by then we are up and having coffee anyway.

Well, you can’t win ‘em all!
We had a beautiful start to the day and were poised to catch a shark to
deploy our shark-cam. But, before one of
the three sharks circling the bait could take it a large tourist boat came over
and anchored right next to us. We tried
to find another spot, but we couldn’t catch a shark before it was too late in
the day to deploy a camera. We’ll give
it another go tomorrow! We did, however,
have a really nice test flight of the quadcopter. The ‘copter has a video camera mounted to it
and we will be able to use it to assess shark abundances on the shallow reef
and in nursery areas. Today was about
making sure we could retrieve it from the boat and picking the best speed and
altitude to fly! The test was a success
and involved no unintended plunges into the Pacific Ocean.

The day started so calm and sunny... |

Landing the quadcopter safely!
We were going to go a nursery area tonight, but we were thwarted by a tropical downpour that is still going on! But the silver lining is that it gave us time to review the footage from the stationary cameras we deployed and retrieved yesterday.
|
|
The rain got even worse than this!
The cameras really did an amazing job, recording for almost seven hours and providing high-quality video. Check out the pictures for a sample – lots of sharks (especially the site closer to the feeding site), tons of fish, turtles, and dolphins! In addition to basic numbers of reef species, we will also be able to investigate the behavior of the sharks and fish.

This blacktip reef shark was at the site far from the shark feeding spot. There are a lot of sharks here! Just way more near the places they can get a free meal. |

Mike and Jeremy very happy to see no leaks in the camera housing! |

Ok, so I got distracted and had to take a picture of the lemon shark while Jeremy finished installing the camera! |

So, after a fairly slow afternoon today, we will have an
ambitious plan for tomorrow. Of course,
that assumes that the rain slows enough to see more than four feet in front of
you. Anyway… the plan is deploy the
stationary cameras, catch a shark to deploy a shark cam and collect samples, collect
samples from other sharks, retrieve shark cam and stationary cameras, go to a
nursery area to sample, then collapse.
There aren’t a ton of days left for Linda and I so we need to pack them
full! Of course, the work will continue
for another month with Jeremy and Johann…and hopefully for years after that!
