We propose a new type of power station unit with wireless data transmission capability, which was not supported by same type of instrument as on the market. Based on this, a novel distributed geophysical data acquisition architecture is also proposed. The proposed instrument loads more stations than the industry-leading LAUL-428 while providing additional wireless data transmission and narrowband Internet of Things remote control.

The CUGB-CS48DAS data acquisition system was primarily designed for seismic purposes. However, we tried to integrate the acquisition circuit for electrical purposes and implemented hardware improvements as well as software updates. Moreover, technology including narrow-band internet of things QC monitoring was also introduced.

The nonuniqueness of geophysical inversions, which is based on a single geophysical method, is a long–standing problem in geophysical exploration. This paper developed a distributed, multi–channel, high–precision data acquisition system. It can achieve high–precision hybrid acquisition of seismic–electrical data and monitor the real–time quality of data acquisition processes using NB–IoT technology. The equivalent input noise is 0.5 μV and the synchronization accuracy is within 200 ns.

High-power transmitters have been playing a significant role in deep electromagnetic exploration. However, a high-power transmitter needs high-voltage support, which is a potential risk for researchers. According to the actual situation of field exploration, we designed a wireless monitoring system. The system offers two advantages, the first of which is high security; the second advantage is simple operation.

We believe that our study full-waveform voltage and current recording device for MTEM transmitters makes a significant contribution to the literature because this full-waveform recording device can be used to monitor the high-power, full-waveform voltages and currents of MTEM transmitters. It has high precision, finer edge details, low noise, and other advantages. Hence, it can be used for real-time recording and transmission to the receiver for coherent demodulation.

In this study, we propose a more accurate method for calculating the current velocity from the nanovolt-scale current-induced electric field as measured using an expendable current profiler (XCP). In order to confirm the accuracy of the proposed data processing method, a sea test was performed, wherein ocean current/electric field data were collected from the sea surface to a depth of 1000 m using an XCP.

We use technical methods of instrument development, calibration experiments, and numerical simulations to develop a new type of in situ stress sensor group using fiber Bragg grating (FBG) sensing technology, which can calculate the in situ stress state of surrounding rock mass by sensing the borehole wall strain. This sensor group lays an important theoretical and experimental foundation for the development and application of FBG hole wall strain gauge.

Heat pulse probes are widely used to monitor soil thermal and physical properties for agricultural and hydrological monitoring related to crop productivity, drought, snowmelt, and evapotranspiration. Changes in the effective probe spacing distance can cause measurement inaccuracy. This paper uses a novel heat pulse probe and theory to compensate for changes in effective distance, thereby enabling more accurate sensor outputs useful for forecasts and predictions of drought and flooding.

This study presents a new instrument called a low-cost albedometer (LCA) composed of two illuminance sensors. The ratio between reflected vs. incident illuminances is called the albedo index and can be compared with actual albedo values. We demonstrate that our system performs well and thus provides relevant opportunities to document spatiotemporal changes in the surface albedo from direct observations at the scale of an entire catchment at a low cost.

Temperature-sensor-incorporated waders worn by the public can give scientists an additional source of information on stream water-groundwater interaction. A pair of waders was equipped with a thermistor and calibrated in the lab. Field tests in a deep polder ditch with a known localized groundwater contribution showed that the waders are capable of identifying the boil location. This can be used to decide where the most interesting places are to do more detailed and more expensive research.

Short summary
Short summary
This paper discussed the effect of temperature on the accuracy of submersible strain gauge pressure transducers. The results show that rapid change of temperature introduces errors in the water level reading while the absolute temperature is also related to the sensor errors. The former is attributed to venting and the latter is attributed to temperature compensation effects in the strain gauges. Performance tests are necessary before field deployment to ensure the data quality.

Short summary
The expendable current profiler (XCP) is a single-use instrument that rapidly measures currents, including the velocity, flow direction, and temperature of seawater. This study improves upon the design of the XCP to reduce the cost of the single-use devices. This has been achieved by adopting signal modulation and demodulation to transmit analog signals on an enamelled wire and digitizing the signal above the surface of the water.
