The mechanical arm of the ROV holds the ADCP current meter in front of a “bubblegum coral” Peragorgia sp. to measure the flow of particles around the coral. Some of the white coral-like animals were collected for the first time by the ROV yesterday and turned out to be a species of sponge. Click image for larger view and image credit.
Filming Begins

The BBC and MBARI have been planning this trip to film the Davidson Seamount for almost two years now, so it seems almost unbelievable that we are finally here! We (and all 18 cases of our filming equipment!) are on-board the R/V Western Flyer, over 70 miles off the coast of California, with a massive underwater volcano right beneath us!
We are here to try to capture video images of this amazing deep-sea seamount for a major new BBC television documentary series called Planet Earth. The series is due to broadcast this year in the UK and next year in the US. There are eleven programs in the series, each one covering a different habitat - such as mountains, deserts, and caves - and its wildlife. We plan to feature Davidson Seamount as part of the final program, which will tell the story of open ocean and deep-sea habitats, and the creatures that live there.
Penny and Warwick from the BBC confer with MBARI scientist Jim Barry and ROV pilots Buck Reynolds and Buzz Scott about lighting modifications that will show off the HD images to their fullest.

There are two parts to our filming plans. First we are using a high definition camera, mounted on the ROV, to gather images from the deep. We are filming the topography of the seamount, as well as all the corals and sponges and other marine life that inhabit its slopes and summits. We caught our first glimpse of the life on Davidson Seamount yesterday, watching images being sent back to the ship from the ROV working on a science dive. We had heard many reports about how spectacular this place was, and they certainly proved to be no exaggeration! Spectacular forests of colorful corals, sponges and anemones stretched as far as the eye could see; a gorgeous expanse of pink, yellow, orange and white. We want to move the lighting on the ROV around a bit tonight, and then can't wait to get started with the camera tomorrow!
Warwick adjusts the light through the round kreisel tank in preparation for filming mid water animals. The white fan keeps condensation from forming on the front window of the tank, allowing for a much clearer view. Click image for larger view and image credit.
The second part of our plan is using a special tank (called a kreisel), which is on loan from MBARI, to film close-up images of mid-water animals (mostly jellies) brought to the surface by the ROV. We spent most of yesterday setting up the kreisel, along with our filming lights and camera, and we've hung a huge black curtain all around it to eliminate problems with reflections from the windows and lights in the lab.
Tonight we're quite excited, as we collected a crown jelly (Atolla sp.) at the end of the day's dive and had the tank ready to film it!
