Oceanographic Floats

infiniTE™ float for data gathering and ocean profiling. Seatrec - USA: Seatrec’s infiniTE™ float is the first subsurface ocean profiling platform powered by clean, renewable energy to address the power constraints of traditional floats. By combining an autonomous profiling float with our proprietary energy harvesting system, we generate electricity from the ocean’s temperature differences, to power sensors that are not feasible on existing profiling floats. Our baseline configuration includes a CTD sensor and can profile three times a day to a depth of 1,000 meters (2,000 on request). The infiniTE™ system is also capable of supporting power-hungry sensors like echosounders and hydrophones.

NiKA - State-of-the-Art Autonomous Maritime Surveillance Float MetOcean Telematics Novatech - Canada: NiKA is a state-of-the-art autonomous maritime surveillance platform that combines advanced technology with exceptional performance. Equipped with a custom hydrophone assembly, NiKA efficiently gathers precise acoustic data by cycling through the water column before surfacing to relay the collected data. This critical information, along with the platform’s real-time position, is then transmitted using the highly reliable Iridium Certus® 100 mid-band satellite service.

Drifters

SVP Drifters MetOcean Telematics Novatech - Canada: The Surface Velocity Program (SVP, iSVP) drifting buoy is a Lagrangian current-following drifter, designed to track water currents (15 metres depth) beneath the ocean surface. Developed for unattended operation in the oceans of the world, the SVP consists of sensors to acquire meteorological and oceanographic data, a battery power source, and a satellite transmitter that relays the data through either Argos or Iridium satellite systems.

Stokes Drifters MetOcean Telematics Novatech - Canada: Stokes Drifter is a compact drifting buoy equipped with GNSS positioning, a sea surface temperature sensor, and Iridium satellite telemetry, which enables the buoy to transmit vital sensor and geo-positional location data in real time.

CODE/DAVIS Drifters MetOcean Telematics Novatech - Canada: The CODE/DAVIS drifter has been designed and tested to meet the performance criteria of the CODE (Coastal Ocean Dynamics Experiment) drifter developed by Dr. Russ Davis of SIO. The CODE/DAVIS drifter is an inexpensive solution to acquire coastal and esturarian water currents within a meter of the water surface.

Wirewalker Del Mar Oceanographic: The Wirewalker is a vertically profiling instrument-platform powered by ocean waves. Through the Wirewalkers rapid profiling and ability to integrate a wide variety of sensor payloads, it brings new life to typical one-dimensional sensor time-series as a 2-D depth-time image where an enormous increase in information and intuition is achieved.
Attached to a free-drifting or moored buoy, the Wirewalker ratchets downward along a suspension wire under wave power. At a predetermined depth (up to ~1000 m), the ratchet releases. The profiler then ascends at its terminal velocity (~0.5 m/s), completely decoupled from sea-surface motion. A very clean data record is obtained to within 1 meter of the sea surface. Typical round trip profiling speeds are 10 meters/minute. Wirewalker in action, watch this video.
