We had two excellent design teams this year work on the problem of building small open source AUVs. They just competed their final projects and have some excellent results. Click on the image below for more details or follow this link: Open Source Nano AUVs
Last week we delivered a brand new build of our SPC system to Rob Campbell at the Prince William Sound Science Center in Cordova, Alaska. The new build features a much larger imaged volume, a new method for attaching the strobe housing to the camera housing, all new electronics including a faster ODROID processor with 8 cores at 2 GHz, and a revised version of our real time object detection software. More details about the system and its application in Rob’s profiling mooring are available on the research projects page: SPC Prince William Sound Science Center
We just wrapped up some extensive field work in Little Cayman with two other research groups from Scripps Oceanography, the Semmens Lab, and the Marine Bioacoustics Lab. The goal of the work was to deploy our AUEs, pingers, plankton net camera, and underwater 360 GoPro camera in the midst of the Nasau Grouper spawning event.
We deployed most of the gear in January but got skunked on the spawning event and also lost a few instruments. We then returned with a smaller team last week to complete the mission and were able to collect some great data with the net camera and the 360 GoPro camera.
For more information about the net camera please see the research page: SPC Net Camera
Last week we completed the first test of our underwater imaging lidar system in a target range off Coronado. The system worked very well and recorded some outstanding images of our resolution target and other targets. The tow platform and supporting system electronics worked well in spite of some less than ideal conditions.
Under a generous, anonymous donation to the Scripps Institution of Oceanography, we have built and deployed a new version of our plankton cameras at the end of Scripps Pier. The installation is named the Scripps Plankton Camera System and consists of two in situ, color, darkfield microscopes with complementary magnification and resolution designed to image plankton in the range of 10s of microns up to 10s of millimeters. For more information about the cameras, and to view the hundreds of thousands of plankton imaged each day, please visit http://spc.ucsd.edu or click on the image below.
Our latest underwater imaging system, the Scripps Phytoplankton Camera (SPC-P), was deployed at the end of Scripps Pier on Sept 19, 2014 and has been running for several weeks collecting over 30,000 images per day. Click on the images below to visit the site:

The Scripps Phytoplankton Camera (SPC-P) was developed under a grant from the W. M. Keck Foundation and an anonymous donor to the Scripps Inst. of Oceanograpy, and in cooperation with the Southern California Coastal Ocean Observing System (SCCOOS). The SPC-P is an underwater darkfield microscope with real-time image processing and object detection. It was designed to detect objects from a few microns up to several millimeters. It employs darkfield illumination. Data from the SPC-P are transferred in real-time to a webserver and database that support an interactive web tool for browsing images and exploring image statistics.
Our latest underwater imaging system, the Scripps Plankton Camera, was deployed at the end of Scripps Pier on March 14 and has been running for more than a month now collecting over 4 million images. Click on the image below to visit the site:

The Scripps Plankton Camera (SPC) was developed under a grant from the Beyster Foundation and in cooperation with the Southern California Coastal Ocean Observing System (SCCOOS). The SPC is an underwater microscope with real-time image processing and object detection. It was designed to detect objects from tens of microns up to several centimeters. It employs darkfield illumination to enhance contrast of transparent objects. Data from the SPC are transfered in real-time to a webserver and database that support and interactive web tool for browsing images and exploring image statistics.
Dr. Jules Jaffe and Dr. Peter Franks gave two very fun and entertaining talks at the OSM 2014 comedy session.
