World's First Fully Autonomous Hydrographic Survey

No Line Plan, No Boat Crew, Just Sensors
During September 2017, the world’s first autonomous hydrographic survey was performed. 'Autonomous' means not by remote control, but rather that the autonomous surface vehicle (ASV) used guidance from survey software to run pre-planned survey lines or automatically generated lines based on sonar coverage, with human interaction possible but not required. The Channel Coastal Observatory (CCO) commissioned 4D Ocean to undertake a hydrographic survey of the seabed offshore of Hurst Spit, Western Solent, using a SeaRobotics ASV 2.5. The pilot survey was supported by the Maritime & Coastguard Agency (MCA) and UK Hydrographic Office (UKHO). By Duncan Mallace, contributing editor, Hydro... (read more)

3’’ Micro CTD for Shirshov Oceanology Institute

FSI has, through its Russian representative, Technopole, shipped a 3” Micro CTD to the Shirshov Oceanology Institute of the Russian Academy of Science. The CTD will be deployed in the Baltic Sea, up to 500 meters. The CTD was equipped with various sensors including an AMT Dissolved Oxygen sensor, AMT pH sensor, Seapoint Chlorophyll Fluorometer sensor and Seapoint OBS/Turbidity sensor. The FIS 3” Micro CTD is a high-accuracy CTD with either direct digital output or 2MB datalogging capability. (read more)

Multi-parameter Real-time Instrument for ROV Use

AML Oceanographic has announced Metrec•X, an externally-powered, multi-parameter instrument that enables you to change the instrument’s sensor load, in the field and on-demand. The Metrec•X can accomodate as many as five Xchange sensor-heads on the end-cap, allowing you to configure the focus of your research on an application by application basis. The instrument can log data and/or output data in real-time. With Metrec•X, dissolved oxygen can be swapped for turbidity, shallow pressure sensors can be swapped for deep, and temperature range can be extended or tightened, as needed. One single instrument meets multiple deployment requirements. Field-swappable sensors also streamline recalibration:... (read more)

Seakeepers Society Licenses its Proprietary Technology Pro Bono

The International SeaKeepers Society allows organisations and institutions to use its proprietary ocean monitoring module, the Ferrybox Sensor Interface Standard (FSIS), without a licensing fee. SeaKeepers continues to actively solicit sensor manufacturers to adopt this technology as a standard ferrybox design in order to develop more efficient ocean monitoring. The modular sensor interface was announced as a possible new global format at the 2006 Oceanology International trade show in London. The SeaKeeper 1000 oceanographic and meteorological monitoring system provides a unifying platform for a wide variety of ferrybox sensors adapted to the FSIS modular interface. It is a fully automated... (read more)

OSIL Supplies Metocean Monitoring Package for GEMS in West Africa

OSIL has supplied a package of metocean instruments to GEMS International for a long-term 13-month oceanographic and meteorological measurement contract for an oil major in West Africa. The equipment included YSI 600 OMS sensors for monitoring turbidity, SonTek Triton wave gauges and SonTek Argonaut XR (Extended Range) current meters. These were all fitted to OSIL-designed subsea mooring frames, complete with Sonardyne location transponders. The SonTek Argonaut XR current meters include a compass/tilt sensor, pressure sensor and temperature sensor, which together with the YSI 600 OMS turbidity sensor and SonTek wave gauges make the XR the centrepiece of the metocean data-collection...

Par Sensors

  Satlantic have introduced a new line of sensors to measure Photosynthetically Active Radiation (PAR). A PAR sensor measures radiation from 400 - 700 nm giving an integrated value of light across this range in units of umol photons*m-2*s-1.   Such a sensor is widely used by oceanographers and limnologists who study primary productivity or phytoplankton physiology in the field or in the laboratory. Satlantic PAR Sensors are currently available in 4 types.     (read more)
