New Publication: Non-invasive estimation of coral polyp volume and surface area using optical coherence tomography

Big congratulations to Jules Jaffe on a recent publication on his approach to a non-invasive way to estimate coral polyp volume and surface area. The article details a set of algorithms that Jules developed to define the boundary between the coral polyp soft tissue and the environment, resulting in the first-ever measurements of surface area and polyp volume based on soft tissue boundaries.  Below is a video of a  rendered point cloud in 3D that shows optical backscatter magnitude in color. If you’re craving coral and interested in learning more about this system, check out the article here.

Scripps Oceanography Cruise on the R/V Sproul

Here are some pictures from our recent research excursion on the R/V Robert Gordon Sproul. We took our new interns with us to earn their sea legs and show them how we get cool detailed photos of plankton.

Further SPC Maintenance… with a Friend

The SPCs are still undergoing maintenance. We recently retrieved them from the pier with friendly cephalopod stowed away under our device. The sucker was a little attached, but we managed to safely return him to the sea. After handling the stowaway, we cleaned off as much kelp and barnacles as we could, then prepped the SPCs for dismantlement and a deep clean. Once they are refitted and redeployed, we will post an update here. Big thanks to our divers, Rich and Taylor, for helping get the cameras out of the water!

SPC Maintenance

The SPCs need software updates and are currently turned off so we can do so. If you’re missing out on your daily dose of plankton, please visit this secondary site where our Swiss colleagues are posting live images from a lake in Switzerland. Once the cameras are back on, we will post an update here. Thank you!
