The CTD-Diver is a submersible datalogger for long-term uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface. …

Download our guide to read the basics of CTD, select the best CTD that fits your research needs between moored CTD and profiling CTD options, and learn more about water sampling technology.

A CTD is a series of small probes that can be deployed independently or incorporated into a variety of observing platforms such as remotely operated vehicles, gliders, or fixed observing buoys. On exploration vessels, a CTD is often attached to a larger metal water sampling array known as a rosette that is lowered into the water via a cable.

2025年2月3日 · Conductivity, Temperature, Depth (CTD) sensors are specialized devices used to measure the electrical conductivity, temperature, and depth of seawater. By gauging these three parameters, users of CTD profilers can infer various other properties of seawater (such as salinity and density) which are vital for understanding oceanographic processes.

The MIDAS CTD is Valeport's premier CTD Profiler. High accuracy sensors (including ±0.01% pressure) and robust titanium design allow reliable operation to 6000m depth, under the harshest conditions. MIDAS CTD also features truly synchronised sampling to ensure that all sensors are sampled at exactly the same point during a profile.

A CTD instrument is an oceanography sonde (French for probe) used to measure the electrical conductivity, temperature, and pressure of seawater. The pressure is closely related to depth. Conductivity is used to determine salinity. The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette.

2023年6月5日 · Researchers from the Catlin Survey team deploy a lightweight CTD under Arctic ice to trace effects of melting ice and warmer temperatures. Changes to the Thermohaline Circulation combined with vast atmospheric, positive feedback loops (that produce large quantities of methane from the melting permafrost) that occur within the Arctic, can have ...

Based on the leading MIDAS CTD Profiler, the Monitor CTD offers excellent performance but in a smaller, lightweight package for shallow water applications. With internal battery pack and large memory, the Monitor CTD is suitable for both self recording operations down to 500m depth, and real time use with a choice of data output protocols.

Monitor groundwater, surface water and air, both during and after in-situ treatment of contaminated groundwater. Continuously monitor water level and quality to establish baseline parameters and see changes during storm events. Removing or depressurizing water from a mine to minimize flooding, stabilize slopes and highwalls, and optimize operation.
