A juvenile, ~10 cm long, Pacific Red Octopus (Octopus rubescens) temporarily moved underneath the VENUS Camera Array for a month. When the oxygen level dropped to near zero, it decided to pack up and move somewhere more hospitable. You would to if you had a dozen squatters (Munida quadrispina) hanging around your neighborhood all day.
Note: You can see the white ball sponges (Suberites sp.) contracting in the video - the first time this behavior has been captured in situ on the bottom of the ocean.

My Workflow:
Images were batched processed to 1440p x 1080p dimensions (Adobe Photoshop) and made into a 15 frames per second (fps) time lapse movie (Avidemux). The time lapse video was then stabilized and re-rendered (Adobe After Effects) because the images did not perfectly overlay on top of one another which resulted in shakey raw footage. Oxygen data profile for the time sequence was downloaded from the VENUS website (http://www.venus.uvic.ca/), processed (Matlab), and plotted (Adobe Illustrator, Adobe Photoshop). The Oxygen profile was then overlaid onto the time lapse video (Adobe After Effects), and an animated time marker was added using keyframes before finalizing the video by pillarboxing into a 1080p HD-video with audio accompaniment (Adobe Premiere Pro).
