Bedload Transport on the Kootenai River near Bonners Ferry, ID (Part 1)
An underwater video camera was mounted on a Helley-Smith bedload sampler and set on the bottom of the river during a flow of around 32,000 cubic feet per second (bankfull). The video was titled with the GPS coordinates, date, and time.

Action within Pu`u `Ō `ō crater
movie shows video taken during today's field visit and overflight. The first portion of the video is taken at the rim of Pu`u `Ō `ō crater, and shows the north vent feeding the lava pond. The lava surface undulates due to rising gas bubbles, and a small overturn is triggered.

Active lava pond within Pu`u `Ō `ō crater
movie shows the active lava pond within Pu`u `Ō `ō crater, imaged with a thermal camera. The video is shown at x60 speed, and covers about 25 minutes. Lava is being supplied to the crater from two vents, one visible in the upper right corner of the image and one out of view in the lower left.

Looking into the Halema`uma`u vent cavity
video from a thermal camera looking into the vent cavity at Halema`uma`u around 3pm today. The video is shown at x4 speed. At the beginning of the clip, the lava level is at a high stand, with slowly migrating crustal plates and little spattering. Eventually, small scale spattering begins in the northeast corner of the pond, accompanied by vigorous degassing.
