CTD, or "Conductivity, temperature, and depth," are the three measurements with which marine scientists "unlock ocean patterns hidden beneath the waves." A group of scientists who believe in accessibility have a crowdfunding project to create OpenCTD, an affordable tool with which citizen scientists and students of the sea can measure these three factors, and learn more about the ocean.
The ocean is not uniform, it its filled with swirling eddies, temperature boundaries, layers of high and low salinity, changing densities, and many other physical characteristics. To reveal these patterns, oceanographers use a tool called the CTD. A CTD is found on almost every major research vessel. 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. The CTD is not cheap. Commercial CTD’s start at more the $5,000 and can climb as high as $25,000 or more. We believe that the prohibitive cost of a CTD is an unacceptable barrier to open science. The price tag excludes individuals and groups who lack research grants or significant private funds from conducting oceanographic research. We want to make this tool--the workhorse of oceanographic research--available to anyone with an interest in the oceans.
NASA today announced that astronomers studying data from NASA’s Great Observatories have found the best evidence yet for “cosmic seeds in the early universe that should grow into supermassive black holes.”
Could you recover a murder victim’s last sight of their killer by extracting it from the retina? Little more than a century ago, forensic scientists thought it might be possible. After all, in 1877 physiologist Wilhelm Friedrich Kühne was able to develop a simple image from an albino rabbit’s dissected eyeball. (Above, the two images […]

Jared Sinclair developed the RSS reader app Unread, which made $10,000 in its first 24 hours on the iOS market. And we’ve all heard the story of Flappy Bird developer Dong Nguyen, whose creation was reportedly earning $50,000 a day at the height of its 2013 explosion. While those are rare examples, they’re also testament to the […]
