AUV | ROV Sensors: AUV | ROV Sensors
Autonomous and remotely operated underwater vehicles are rapidly evolving to fill scientific niches, many with capabilities otherwise unattainable through traditional manned research at a fraction of the operating cost. Sea-Bird Scientific offers a line of sensors uniquely designed for integration with various unmanned underwater vehicles, expanding data potential and opening new doors for unique research opportunities. While Sea-Bird Scientific originally designed most sensors for stand-alone applications, we have redesigned and miniaturized popular product lines meet the specific operational requirements of unmanned research platforms: a 1 kg CTD can now replace a 10 kg CTD while maintaining the same accuracy, and a precision optical sensor can now take up half the space while recording the same data channels.

CTDs: Moored
Moored sensors measure water parameters in one location over an extended period. These instruments are often battery-powered and save banks of data in their internal memory for later retrieval. Moored CTDs and sensors form the backbone of long-term studies on buoys, docks, and other fixed platforms, providing valuable time-series of data for monitoring and research applications.

Radiometer
HyperOCR
Hyperspectral ocean color radiometer (HOCR) sensors are designed for applications where performance, size and power are key constraints. HOCRs can be mounted on real-time profilers, moored on autonomous deepwater buoys, installed in autonomous underwater vehicles, as well as on ships and airplanes for above-water optic applications. HyperOCR sensors are fully digital optical packages, providing 136 channels of calibrated optical data from 350–800 nm.

CTDs: Profiling
Profiling CTDs make continuous measurements as they travel through water. When lowered over the side of a ship or integrated with an autonomous vehicle, they map a vertical column of water's characteristics. Compared to moored CTDs, profiling CTDs account for dynamic errors introduced by moving through water and sample rapidly to generate a high-resolution dataset over a short period of time. Sea-Bird Scientific profiling CTDs are:*Designed to perform under unique dynamic conditions found on moving platforms.*Pumped and ducted for constant flow to match temperature and conductivity response.*Plumbed so measurements are made on the same sample of water with a predictable delay and predictable flow effects.*Built with a rugged design for shipboard and autonomous deployments.

Optical Sensors: Transmissometers
Transmissometers provide information about the optical properties of natural water by measuring the transmittance or attenuation of incident radiation. Sea-Bird Scientific offers transmissometers and an attenuation sensors for a variety of applications, including AUVs, deep ocean, and profiling floats.

Water Samplers: Water Samplers
A water sampler is often used in conjunction with a CTD. The water sampler collects 1 or more actual samples of water for analysis in the lab after recovery of the package. The water samples can be used to verify the accuracy of data measured by the instruments on the package, and/or to provide additional information that cannot be measured with an instrument in the field. Sea-Bird water samplers can be controlled (i.e., bottles closed) from deck via a Sea-Bird deck unit and software, or can be pre-programmed to close bottles at desired depths. Sea-Bird manufactures two water samplers: the SBE 32 Carousel (up to 36 bottles, 1.7 - 30 liters, available in regular, compact, and sub-compact sizes, for depths to 10,500 m) and the SBE 55 ECO (small, 3- or 6-bottle sampler for depths to 600 meters).
