What does an OpenCTD mean to marine ecologists?

kerseysquaeThe OpenCTD–a conductivity-temperature-depth (or CTD) sonde is considered the ‘work-horse’ of oceanography. Three relatively simple probes constitute the CTD and allow researchers to make basic water quality measurements. These fundamental measurements are the foundation upon which marine science is built.  As was aptly stated by Dr. Thaler, “Rare is the scientific expedition–whether it be coastal work in shallow estuaries or journeys to the deepest ocean trenches–that doesn’t begin with the humble CTD cast.” CTD’s are commercially produced by a number of companies, but the associated cost of purchasing one of these instruments (ranging from $5,000 to $25,000) is an unacceptable barrier of entry into marine science. Thus the OpenCTD project—an attempt to construct a low-cost CTD that is scientifically applicable—was born.. Our goal is to produce free blue-prints, instructions, and schematics for the physical construction and calibration of a low-cost, open-source CTD.  The final cost of the device will be low enough (~$200) to be readily accessible to those interested in constructing one, regardless of financial limits.

Technology in water? That seems a bit counter-intuitive  doesn’t it? Well, Dr. Kersey Sturdivant, during his undergraduate and graduate years, denied the golden rule of electronics and submerged a video camera under water. But this is not your typical Canon Powershot D10. This is WormCam. As much as I love thumbing through magazines and flipping page … Read More “Meet WormCam” »
