Moored / Time Series Instruments

A Moored instrument measures water parameters in one location, over an extended period of time, providing a time series of data. 

A CTD measures Conductivity, Temperature, and Depth. Despite the name, all CTDs actually measure pressure, which is not quite the same thing as depth. The relationship between pressure and depth is a complex one involving water density and compressibility as well as the strength of the local gravity field. The CTD data can be used to calculate salinity, density, sound velocity, and other parameters of interest. The term CTD is often used today to describe a package that includes the actual CTD as well as auxiliary sensors to measure other parameters (such as dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.). The term Sonde is sometimes used as an alternative to CTD. To reduce costs, a moored CTD may not include a pressure sensor, because the deployment depth is known (approximately); the pressure sensor is optional in most Sea-Bird moored CTDs.

Sea-Bird also manufactures moored temperature sensors as well as instruments for high-accuracy pressure measurements (wave and tide recorder, bottom pressure recorder, and tsunami sensor).

See the following for more details on CTDs:

Measures conductivity, temperature, depth, dissolved oxygen, pH, turbidity, and chlorophyll. It is ideally suited for extended deployments in remote, biologically rich environments, for depths to 350 m.
The SUNA V2 UV nitrate sensor is the ultimate chemical-free solution for autonomous monitoring of nitrogen-based nutrient concentrations in ocean, estuarine, and high turbidity freshwater environments to 500 m.
SBE 16plus V2 CTD
Moored Conductivity, Temperature, (optional) Pressure, and up to seven auxiliary sensors, at user-programmable intervals.
SBE 16plus-IM V2
Moored Conductivity, Temperature, (optional) Pressure, and up to seven auxiliary sensors, at user-programmable intervals, communicating via Inductive Modem (IM) telemetry.
 SeapHOx™ Ocean CT(D)-pH-DO Sensor
The SeapHOx™ combines the SeaFET™ pH sensor with the SBE 37-SMP-ODO MicroCAT CTD+DO sensor.
The Deep SeapHOx™ combines the Deep SeaFET™ pH sensor with the SBE 37-SMP-ODO MicroCAT CTD+DO sensor. The Deep SeaFET adapts the MBARI/SIO/Honeywell Deep-Sea DuraFET technology to measure pH in a deep moored package.
SBE 19plus V2 with optional cage, SBE 5P pump, & SBE 43 DO sensor
Profiling or moored Conductivity, Temperature, Pressure, and up to seven auxiliary sensors, with 4 Hz sampling, and internal memory and batteries.
SBE 52-MP with optional Dissolved Oxygen Sensor
Conductivity, Temperature, Pressure, optional Dissolved Oxygen, at 1 sample/sec (1 Hz). RS-232 or Logic Level interface, no batteries, small memory — for use on moored profiling vehicles that can supply power and acquire data.
Measures and records conductivity, temperature, depth, and optical dissolved oxygen. It is ideally suited for extended deployments in remote, biologically rich environments, for depths to 350 m.
Specifically designed for long-term coastal and freshwater environmental data logging. Its rugged design, compact size, file management capabilities and low sleep current requirements make it ideal for remote systems.
The Water Quality Monitor (WQM) is designed to deliver core biogeochemical water quality parameters in coastal ecosystems from a single integrated package.
Moored Conductivity, Temperature, (optional) Pressure, and (optional) Dissolved Oxygen measurements, at user-programmable intervals. Now also available with pH (37-SMP-ODO with SeaFET or Deep SeaFET). Available with RS-232, RS-485, SDI-12, and Inductive Modem interfaces.
SBE 39plus - just a few of the configuration choices
Temperature and (optional) Pressure, at user-programmable intervals. Internal memory and battery pack, RS-232 and USB interface. Configurations with internal or external thermistor, external connector, pressure.
SBE 39plus-IM
Moored Temperature and (optional) Pressure, at user-programmable intervals. Internal memory and battery, Inductive Modem (IM) interface.
