EIVA Releases Accurate Time Tagging Unit

EIVA has released its Accurate Time Tagging Unit (ATTU), the successor of the EIVA TimeBox. The EIVA ATTU is a time-synchronised interface unit for precise time tagging of serial communication data from any sensor used in marine surveys. The ATTU thus facilitates time tagging of sensor data with accuracy better than 50 microseconds.   This accuracy is obtained through interface with GPS PPS signal information and sophisticated application of Kalman filtering techniques to stabilise the internal clock of the ATTU. As the ATTU is synchronised through use of GPS the performance and accuracy is dependent on the availability and quality... (read more)

Cone Penetration Testing Unit for UTEC

UTEC has taken delivery of a deep-push seabed Cone Penetration Testing (CPT) unit to support its Asia Pacific, Middle East and Australian geotechnical operations. Manufactured by Netherlands-based AP van den Berg, the Roson CPT unit includes a recently upgraded 75kN twin-drive thrust for deeper seabed soil investigations. Offshore applications will include pre-installation analysis for oil and gas construction, civil works, subsea telecommunications, and renewable energy infrastructures in both shallow and deep water environments. The twin wheel drive seabed CPT system uses in-situ piezocone CPT testing with cones from 5 to 15cm2, including T-bar and dissipation tests, for penetration to depths... (read more)

Ocean Noise Reference Network Established

In mid-October 2015, a network of 11 ocean noise reference stations was established in US waters to measure changes and trends in natural and man-made ocean noise. Monitoring baseline ocean noise is important to understand both natural and anthropogenic changes in the marine ambient sound environment. Natural sounds ranging from whale calls and volcanoes to anthropogenic sounds from shipping and oil/gas exploration are recorded by the moored, underwater hydrophones developed by PMEL engineers and scientists and deployed in collaboration with NMFS-OST, all the Fisheries Science Centers, NOS Marine Sanctuaries, and the National Park Service. The establishment of a long-term record provides... (read more)

Global Decimetre-level Positioning without Reference Station

Altus Positioning Systems, Germany, has introduced the APS-3L high-precision GNSS receiver. The APS-3L is the first GNSS survey receiver on the market with embedded L-band capability to work with the Veripos TERRASTAR-D differential correction service. When out of wireless range of terrestrial UHF radios or cellular networks, the system seamlessly transitions to L-band satellite connections for continuous decimetre-level PPP. It was shown for the first time to the worldwide surveying community at the Intergeo trade fair in Hannover, Germany, in October 2012. The APS-3L provides real-time kinematic (RTK) and precise point positioning (PPP) with integrated embedded UHF, cellular, and L-band... (read more)
