The YSI CastAway CTD is a lightweight, easy to use hydrographic instrument designed for quick and accurate temperature, salinity, and sound speed profiles.
Field Ready and Rugged
The CastAway CTD is a hand deployable conductivity, temperature, and depth instrument for hydrologic profiling. An integrated LCD screen displays an intuitive user interface for deployment and immediate review of collected data including both statistics and profile plots. The watertight, compact design features a tough rubber jacket for additional durability in harsh conditions. The system utilizes Bluetooth wireless communication, so no field cables or connectors are needed. Two AA batteries power the CTD for several days at a time and are easily replaceable without the use of any tools. This handheld device is an affordable, rugged, and portable instrument that simplifies any water profiling application.
With three taps of a magnetic stylus pen, simply drop the CastAway in the water, pull it up, and have conductivity, temperature, and depth measured in minutes. An attractive LCD screen provides easy access for setup, deployment, and immediate data review. Integrated GPS virtually eliminates the need for field notes. The beginning and end of every cast is logged to the internal recorder with position and time.
CTD Profiling and Analysis Software
Reviewing and analyzing CTD profiling data has never been easier. The included GIS software quickly downloads data from each of your CastAway CTDs automatically over Bluetooth to show the location of each cast on an interactive map. Customize your CTD data, GPS information, and plot comparisons all in one place. Analysis, plotting, editing, and exporting of data are quick and easy tasks.

Georgia has about 30 percent of all the existing salt marsh on the United States’ eastern seaboard. Much of that is expected to migrate inward with predicted sea level rise in the future, possibly impacting plant and animal habitats and commercial fisheries. Understandably, scientists have many questions for what these moving marshes could bring about. A few at the University of Georgia’s Skidaway Institute of Oceanography and Georgia Southern University have embarked on a study to model what the state’s coasts will look like within the next 100 years. Scientists are focusing their efforts on five coastal river systems: the Savannah, Ogeechee, Altamaha, Satilla and St. Marys. Work has been completed to gauge saltwater intrusion on three of those.Read More
In the wake of various water quality crises from Flint, Michigan and Puerto Rico, there is a growing interest and demand among consumers for home water testing. Enter DIY water testing kits like Tap Score by SimpleWater. Tap Score in particular was conceived of and launched by former UC Berkeley grad student John Pujol and co-founder and CTO Julio Rodriguez. “In 2015 we began testing small and rural communities for arsenic in their water,” Pujol explains. “We found it much more frequently than we expected, and also discovered that people in these towns greatly appreciated someone telling them what was in their water and how to fix it.Read More
For most of us, when we think of nitrate and agricultural pollution, we think of the nitrate that comes from fertilizers and leaches quickly through the soil. The effects of this kind of pollution are realized quickly, but researchers from Lancaster University and the British Geological Survey have recently revealed an underground time bomb of nitrate in rock. In the recent paper , lead author and hydrogeologist Matthew Ascott and the team quantified the vast amounts of nitrate that exist within the layers of rock between the soil and groundwater tables for the first time. They discovered that there is about twice as much nitrate lurking in this rocky vadose zone than there is in the soil—up to 180 million tons—nitrate that has been omitted from global scale nitrogen budgets.Read More
