Why Buy From Fondriest?


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.

Saltwater Intrusion, Elevation Data Gathered For Georgia Sea Rise Modeling

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.

ESPniagara Tracks Algal Toxins In Lake Erie, Protects Drinking Water

It may have taken 20 years and $20 million to develop, but Lake Erie researchers working to fight harmful algal blooms (HABs) now have a new tool to safeguard drinking water: ESPniagara. The advanced sampler has been called a “lab in a can” for its ability to sample microcystins, the most common algal toxin these days, in almost real time. The big gadget’s name is a mashup between “ESP,” for environmental sample processor, and the name of Admiral Oliver Hazard Perry’s ship during the War of 1812. “We wanted to name it something that was significant to Lake Erie,” said Tim Davis, molecular biologist and lead HABs researcher at the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Lab (NOAA GLERL) in Ann Arbor, Mich.

Dynamics Of Fluid Movement Studied From Space

As a research project underway at the University of California (UC) - Santa Barbara shows, sometimes you’ve got to leave the Earth to adequately study some of its most basic processes. Researchers at the university are partnering with the International Space Station to complete an investigation of fluid dynamics. The lab in microgravity is providing them with an important dataset for gauging the impacts of the force on our planet’s fluid movement. The experiments in space , to be run by astronauts, are fairly straightforward. Cameras will be employed to monitor different sediment particles as they interact with one another in fluid in near-zero gravity. Light shone at and through the setups will help researchers track the motion and observe the density of the particles.
