nke Instrumentation's SAMBAT is an Autonomous Multiparameter Probe with Brush and Teletransmission. SAMBAT is used to measure and record the main physical water parameters (temperature, depth, conductivity for the calculation of salinity, turbidity, ... Morefluorescence, dissolved oxygen and pH) on a period of time up to several months.

SAMBAT uses a brush to protect the fluorescence, turbidity, and dissolved oxygen sensors from biofouling.
Robertson Geo's Natural Gamma Probes - Triple Gamma & Ultra-Slim Gamma Probes - measure the activities of naturally occurring or man-made isotopes. Principle of Measurement... More
The probes are based on scintillation gamma detectors which measure the natural gamma radiation released from potassium and the decay products of uranium and thorium in the borehole.
Robertson Geo's High Resolution Acoustic Televiewer (HRAT) provides a continuous high-resolution, oriented ultrasound image of the borehole wall. The probe uses a fixed acoustic transducer and a rotating acoustic mirror to scan the borehole walls with ... Morea focussed ultrasound beam. The amplitude and travel time of the reflected acoustic signal are recorded as separate image logs.

Features such as fractures reduce the reflected amplitude and appear as dark sinusoidal traces on the log. The travel time log is equivalent to a 360°-arm caliper and shows diameter changes within open fractures and 'break-outs'.

Directional information is also recorded and used to orient the images in real time.
Robertson Geo's Formation Density probe uses dual shielded detectors to provide a boreholecompensated density measurement with good bed-boundary resolution. Principle of Measurement... More
The probes contain a detachable 137Cs gamma source and two scintillation gamma detectors. The active windows of the source
and detectors are maintained in contact with the borehole wall by a motorised caliper arm. Gamma radiation back-scattered by the
formation (Compton effect) reaches the detectors where the relative count rates provide a measure of formation density.
Robertson Geo's Density Guardlog probe uses dual shielded detectors to provide a borehole compensated density measurement with good bed-boundary resolution, similar to the Formation Density probe. The Density Guardlog probe offers an additional LL3 focussed ... Moreelectrical measurement with good vertical resolution and depth of investigation.

Principle of Measurement
The Density Guardlog probe contains a detachable 137Cs gamma source and two scintillation gamma detectors. The active windows of the source and detectors are maintained in contact with the borehole wall by a motorised caliper arm. Gamma radiation back-scattered by the formation (Compton effect) reaches the detectors where the relative count rates provide a measure of formation density.
Robertson Geo's 3-Arm Caliper probe provides a single continuous log of borehole diameter, as recorded by three mechanically coupled arms in contact with the borehole wall. 710mm, 1000mm and 1500mm range calipers are available to suit a range of well ... Morediameters. The caliper is a useful first log to determine the borehole conditions before running more costly probes or those containing radioactive sources.

Principle of Measurement
Opening and closing of the motor-drivercaliper arms is by surface command, allowing the probe to run into the borehole with the arms retracted. Once opened, the spring-loaded arms respond to borehole diameter variations as the probe is raised up the borehole.
Robertson Geo's High Resolution Optical Televiewer (Hi-OPTV) provides a continuous very high resolution oriented image of the borehole walls using a conventional light source. A unique optical system based on a fisheye lens allows the probe to survey ... More360 degrees simultaneously. This information is processed in real time to produce a complete 'unwrapped' image of the borehole oriented to magnetic north. The probe offers superior resolution to the High Resolution Acoustic Televiewer (HRAT) and produces images in real colour. While, unlike the HRAT, it can operate in air-filled boreholes, it is unsuitable for boreholes containing mud or cloudy fluids.

WellCad™ Image-Processing Software
WellCad™ is a Windows-based package for processing, interpreting and displaying acoustic and optical televiewer image logs. Standard log presentations include tadpole and stick plots, stereographic projections of poles to planes and azimuth frequency diagrams. The synthetic core display allows convenient comparison of log and field data for orientation of fractured or incomplete core sections.

Blue Robotics BlueROV2 — The World's Most Affordable High-Performance ROV Ocean research, exploration, and adventure are all made easily accessible by our flagship product, the BlueROV2. It provides the capabilities of a high-end commercial miniROV at ... Morethe price of the most basic commercial ROVs, making the BlueROV2 the world's most affordable inspection and research-class subsea vehicle.

The smooth, stable, and highly maneuverable ROV is comprised of six thrusters, a rugged frame, and quickswappable batteries. Powerful but dimmable lights provide excellent illumination for the live HD video feed.

Like all Blue Robotics products, we created the BlueROV2 with high-quality parts, meticulous design, and rugged reliability with proven success in the field.

Equipped with six powerful T200 thrusters and Basic ESCs, the BlueROV2 has the best thrust-to-weight ratio in its class to perform demanding tasks. It is ideal for operations in shallow to moderate waters, with a standard 100m depth rating and up to 300m tether lengths available. 

The BlueROV2 uses the open-source ArduSub software and PixHawk autopilot to provide autonomous capabilities rarely seen in mini ROVs and hackability paralleled by none. Blue Robotics actively develops and updates its software to enhance the BlueROV2's functionality.

Your vehicle will arrive almost-ready-to-dive, with pre-built sub-assemblies and instructional materials to make the experience as straightforward and enjoyable as possible. Additional items including the topside computer, gamepad controller and batteries are not included.

At Blue Robotics, we are committed to creating quality products that are accessible to any explorer.
Robertson Geo designs and builds its own range of winches of varying capacities for deploying subsurface probes on 4-core or co-axial cable. Each winch is precision engineered for reliable use in the mostchallenging field applications. The winches are ... Morefully compatible with the Micrologger2 surface system and the full range of Robertson Geo probes, for depths of up to 3,000m.

Working experience by Robertson Geo offshore logging crews has led to the modification of the 2000m Winch and the introduction of a Marine variation to resistcorrosive, saline conditions. The communications box is waterproofed and filled with silicon to protect the electronics. Grade 316 stainless steel has been introduced to replace standard steel components. 316 contains the alloy molybdenum, significantly enhancing corrosion resistance, especially for more saline orchloride exposed environments. 316 components include structural frames, depth wheel, panels, spacers, shafts and gears, sprockets and chains.
The 8 ft WAM-V was designed from the ground up with portability in mind. Able to be loaded in the back of a standard pickup truck, or checked onto a domestic airline flight, the 8 ft model brings disruptive WAM-V technology to an expanded field of operations. ... MoreWith the same exceptional stability of all WAM-Vs, this vessel will fill a gap in the market by bringing improved data acquisition to rough seas and hard-to-reach environments.

The first WAM-V 8 is slated for delivery in the first quarter of 2019 with full production to begin in the second quarter. Pre-order now to reserve yours.
