3D Photogrammetry of a brain coral

-


These 2 videos show a 3D render of a small brain coral from Bermuda. The program Autodesk 123 Catch generated the 3D wireframe model from a series of 40 photographs, all in less than 15 minutes.

We plan to use this technology to measure coral growth in 3D, as well as develop 3D models of coral reef benthic communities from underwater photo or video sets.

Stay tuned for more 3D fun in the weeks ahead!

Clod cards are what??

By Brittany Huntington, Doctoral Student, RMSAS Univ. of Miami and BREAM summer graduate intern, funded by ACP What are these? Fossilized marshmallows? White chocolate petite fours? No no…this is real science people! This abundance of ice cube shaped trapezoids are nicknamed “clod cards”: a simple yet effective way to measure water movement as a proxy for current and flow exposure at underwater sites (developed by Doty et al., 1971). The mechanism is straight-forward. These plaster of paris ‘clods’ are all identical in composition, shape and size. Each clod should therefore dissolve slowly underwater at a constant rate. By weighing the dry clod cards before deployment, leaving them underwater for a fixed time period (usually between 24-48 hours) and then collecting them and re-weighing each clod, we can determine the precise weight of plaster of paris lost from each card. Clods losing more weight were exposed to greater water flow than cards exposed to less water flow. I am a visi
