Oceanography for Everyone – Help us build a CTD!
Head over to our Rockethub Page for more information!
Conductivity, temperature, and depth (CTD). With these three measurements, marine scientists can unlock ocean patterns hidden beneath the waves. 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.
We’re building a CTD, but we need your help!
The ocean belongs to us all. Let’s ensure that we have access to the tools needed to study it.
