The field proven sensor measures and records temperature ensuring long term data stability. Depending on the sample recording interval the Hydro-T can collect high quality data for one month to two years before the battery needs to be replaced.
While every application does not require the Hydro-T’s high stability this capability preserves the initial calibration accuracy and ensures less frequent (or no) calibrations. For example, if you only need ±0.01°C accuracy, you will not have to calibrate the Hydro-T for at least 5 years.
The Hydro-T is based on field-proven Sea-Bird technology. Cutting edge design and manufacturing make extreme accuracy and precision possible, and the world-leading sensor calibration delivers it.
The Hydro-pH is a pressure-balanced glass-electrode pH probe capable of providing in situ measurements. The sensor is a modular, self-contained package that is easy to install, service and calibrate.
The Hydro-pH can be codeployed with the HydroCAT when connected to an external datalogger or it can connect directly into the WQM.
Sea-Bird Scientific introduces SeaOWL UV-ATM, a new in-situ oil-in-water sensor. Based-upon the highly successful WET Labs ECO sensor, Sea-Bird Scientific has developed an industry-leading oil-detection technology with 5X optical resolution improvement over its predecessor.
SeaOWL UV-ATM measures crude oil-in-water using the same UV-A excitation and blue emission wavelengths (370 nm EX/ 460 nm EM) currently used in the ECO CDOM fluorometer. The SeaOWL UV-ATM improves the resolution and range of the ECO with a greater depth of field, optimized electronics and dynamic gain stage modulation. The new dynamic gain provides industry leading sensitivity across a large detection range making saturation unlikely in even the most heavily impacted environments. The compact SeaOWL UV-ATM design also includes chlorophyll fluorescence and 700 nm backscattering measurements to discriminate crude oil from phytoplankton and other natural sources of FDOM.
Sea-Bird's 9 plus CTD is the primary oceanographic research tool chosen by the world's leading institutions.
Referred to as 911plus when used with 11plus CTD Deck Unit (real-time data acquisition) or 917plus when used with 17plus V2 SEARAM Recorder & Auto Fire Module (autonomous operation).
The 911plus, consisting of the 9plus underwater CTD and 11plus V2 Deck Unit, is a premium real-time CTD accurate to the highest international standards. It features high resolution sampling (24 Hz), pump-controlled T-C ducted flow, up to 10500 meter (15,000 psia) depth capability, maximum auxiliary sensor flexibility, and modem channel for Water Sampler control. The 911plus has eight 12-bit A/D channels, and supports redundant C&T sensors or custom auxiliary digital inputs.
The SBE 16plus V2 (Version 2) SEACAT Recorder measures temperature and conductivity (pressure optional) and provides high acccuracy and resolution, reliability, and ease-of-use on moorings and other long-duration, fixed-site deployments. Compared to the previous 16plus, the V2 incorporates an electronics upgrade and additional features, with six differentially amplified A/D input channels, one RS-232 data input channel, and 64 MB FLASH memory. Data can be output in XML as well as ASCII and HEX formats. Firmware upgrades can be downloaded through the communications port, without opening the instrument.
The SBE 17plus V2 Searam is used to operate any SBE 9plus CTD underwater unit in self-contained internal recording mode, without the need for conducting winch cable. Auxiliary sensors connected to the 9plus are also supported. The Searam also includes Carousel Auto-Fire capability: when the Searam and 9plus CTD are integrated with an SBE 32 Carousel Water Sampler, users can collect water samples at pre-programmed depths and record CTD data with one autonomous system. CTD profile data and separate bottle summary data are stored in memory, and can be quickly uploaded to a computer without opening the Searam. The Searam is typically installed in the CTD cage with the 9plus CTD Other mounting options are possible for Compact Carousels (SBE 32C) or custom applications. Data acquired using the Searam has the same quality and resolution as real-time data obtained with conductive-cable systems.
The SBE 19plus V2 (Version 2) Seacat Profiler CTD measures conductivity, temperature, and pressure (depth) and provides high accuracy and resolution, reliability, and ease-of-use for a wide range of research, monitoring, and engineering applications. The pump-controlled, T-C ducted flow configuration minimizes salinity spiking caused by ship heave and allows for slow descent rates without slowing sensor responses, improving dynamic accuracy and resolving small scale structure in the water column.
The SBE 25plus Sealogger is the ideal research-quality CTD profiling system for coastal, estuarine,
and budget-minded deep-water deployments. The battery-powered 25plus records data in memory,
eliminating the need for a large vessel, electro-mechanical sea cable, and on-board computer. The
25plus can also transmit data in real-time.
The 26plus combines Sea-Bird’s non-volatile FLASH memory with a stable time base, precision thermometer, and
Quartz crystal pressure sensor to provide wave and tide recording of unprecedented resolution and accuracy, along
with high-quality temperature information. An input connector for an optional SBE 4M conductivity sensor is standard.
An innovative design free of the reliability problems
associated with motor-driven types. The Carousel has no moving-shaft seals that can bind up at low
temperatures or under pressure because each bottle position has its own magnetically-activated
lanyard release latch. Only the magnetic field - not a moving part - links the Carousel's lanyard
release mechanism with the pylon control electronics.
Sea-Bird's Carousel has been extensively deployed throughout the world's oceans, where it has built
a reputation for reliability and ease of use. The Carousel has rapidly become the standard for
oceanographic water sampling.
The rack-mountable SBE 33 provides power and real-time data acquisition and control for an SBE 32 Carousel Water Sampler that has the SBE 33 interface option installed in its pylon. The SBE 33 is compatible with all Carousel sizes -- standard, compact, and sub-compact. When powered and controlled by the SBE 33, the Carousel can be used:
•with an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD
•without a CTD
•with a Neil Brown Mk III CTD (requires optional interface for both SBE 32 and 33)
The SBE 33 can also be used to provide power and real-time data acquisition and control for the smaller SBE 55 ECO Water Sampler used with an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD, or no CTD.
