Abstract:

The subject of the study is the problem of the decline degree of the information content of geophysical data when switching from land surveys to low-altitude geophysical survey using unmanned aerial vehicles. The research involves a comparative analysis of the information content of the unmanned aerial vehicle survey results and those of the land magnetic survey. The conducted research allowed to present the observed values of the magnetic field obtained by both survey methods within the same area as well as the final information products in the form of the results of filtering and three-dimensional data inversion. It is shown that visual analysis of maps of the full vector of magnetic field strength gives the impression of a lower information content of magnetic survey performed by unmanned aerial vehicles. However, the data having been processed create final information products of identical information content. This concerns both the results of three-dimensional modeling of the effective magnetic susceptibility, and maps and plots of the anomalous magnetic field after filtering in a sliding window. The negative impact of geological interference from morainic deposits on ground data is also shown. Local magnetic anomalies based on unmanned aerial vehicle survey results can confidently correlate with land survey anomalies, whereas the data collected during low-altitude aeromagnetic survey using unmanned aerial vehicles have a lower error probability. The conclusions refer to a specific case and cannot be unambiguously applied to any geological situation, however, the authors believe in the typicality of this example.

Full text

Abstract:

In recent times, surveys employing tensor gradiometers have been used in mineral exploration. Some reasons for this are potential advantages such as improved resolution, data interpolation, noise suppression and relative insensitivity to survey orientation. The last two potentialities are particularly germane to marine CSEM surveys, which are typically sparsely sampled and require processing of measured fields to ensure that the correct vector component is analysed. In a series of numerical modelling studies of typical frequency-domain CSEM surveys in both shallow and deep water columns, this paper shows that tensor gradient measurements have advantages over conventional CSEM measurements in terms of target definition, especially when survey lines do not fall over target centres.

Abstract:

A.C. magnetic fields exist throughout every EM site. For a given site, then, how does one predict when EM interference problems are likely to occur? Obviously, an accurate, meaningful magnetic field survey is the first step toward evaluating site EM magnetic field compatibility. Consequently, this article in our series will describe measurement equipment and techniques for achieving accurate, unambiguous magnetic field characterization.In a previous article (Part II: “ACMF/EM Antipathy”, Microscopy Today, November ‘95), we examined several types of sources which produce alternating current magnetic fields (ACMFs). In near proximity, or at sufficiently high power levels, any of these sources (e.g., transformers, power cabling, ground currents, and/or combinations thereof) can affect EM operation. In this article, we will review specific instrumentation and methods for accurate magnetic field survey data collection and interpretation, a necessary prior step for EM interference prediction and resolution.

Abstract:

Up to the present waypoint in this series on EM site magnetic fields, we have identified typical sources of time-varying magnetic field intensities, examined salient field characteristics and illustrated correct survey methods. Our goal this month is to analyze data collected at a proposed site and answer the key question of whether or not the candidate site is, as far as magnetic fields go, acceptable for EM use. In the process of analyzing the magnetic field survey data we will define some of the interpretive techniques involved and observe the distinction between localized (a.c. power) and non-localized (geomagnetic) time-varying fields. Finally, we will discuss the implications of EM susceptibility threshold vs. measured field ratios when considering remedial site shielding.

Abstract:

The use of light and ultralight unmanned aerial vehicles (UAVs) for magnetic data acquisition can be efficient for resolving multiple geological and engineering tasks including geological mapping, ore deposits’ prospecting, and pipelines’ monitoring. The accuracy of the aeromagnetic data acquired using UAV depends mainly on deviation noise of electric devices (engine, servos, etc.). The goal of this research is to develop a nonmagnetic unmanned aerial platform (NUAP) for high-quality magnetic surveys. Considering parameters of regional and local magnetic survey, a fixed-wing UAV suits geological tasks better for plain area and copter type for hills and mountains. Analysis of the experimental magnetic anomalies produced by a serial light fixed-wing UAV and subsequent magnetic and aerodynamic modeling demonstrates a capacity of NUAP with internal combustion engine carrying an atomic magnetic sensor mounted on the UAV wings to facilitate a high-quality magnetic survey.

Abstract:

Magnetic fields have attracted considerable attention in indoor localization due to their ubiquitous and infrastructure-free characteristics. This survey provides a comprehensive review of magnetic-field-based indoor localization methods. We first introduce characteristics of the magnetic field, its advantages, and its challenges. We then describe the magnetometer model and the effect of ferromagnetic interference. We also present coordinate systems commonly used for magnetic field localization and describe their transformation relationships. We then compare the existing publicly available magnetic field benchmark datasets, present magnetometer calibration algorithms, and show how efficiently magnetic field maps can be built. We also summarize state-of-the-art magnetic field localization methods (e.g., magnetic landmarks, dynamic time warping, magnetic fingerprinting, filters, simultaneous localization and mapping, and neural network). The smartphone-based pedestrian dead reckoning approach is also reviewed.

Abstract:

AbstractThe first two years of the Sloan Digital Sky Survey have discovered over 50 new cataclysmic variables, of which four are confirmed Polars, two others are likely candidates and several others are good candidates for Intermediate Polars or SW Sex stars. Several systems have unusual characteristics, including large amplitude, narrow cyclotron humps indicating a very low temperature shock on a cool white dwarf, or very deep eclipses. Although SDSS is finding a variety of systems, it is ideal for picking up the low mass transfer rate magnetic systems missed in X-ray surveys and in past optical surveys with brighter limits. Thus, it is providing us with a clearer picture of the range of conditions existing in magnetics CVs.

Abstract:

This paper presents a survey of the methods of statistical physics which are applied to the problem of thermal agitation in magnetic materials. The main focus of the work is the stochastic dynamics described by the Landau-Lifshitz-Gilbert equation for which most analytic results are known, and which has been most commonly used in numerical simulations. We also present the much more recent Landau–Lifshitz–Bloch equation and the numerical calculations describing magnetization dynamics close to the Curie point. The paper is concluded by a description of the newly introduced jump-noise and of the Barkhausen jumps.

Abstract:

Context. M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but we are still lacking a consistent picture of the link between the magnetic fields and underlying dynamo mechanisms, rotation, and activity. Aims. In this work we aim to measure magnetic fields from the high-resolution near-infrared spectra taken with the CARMENES radial-velocity planet survey in a sample of 29 active M dwarfs and compare our results against stellar parameters. Methods. We used the state-of-the-art radiative transfer code to measure total magnetic flux densities from the Zeeman broadening of spectral lines and filling factors. Results. We detect strong kG magnetic fields in all our targets. In 16 stars the magnetic fields were measured for the first time. Our measurements are consistent with the magnetic field saturation in stars with rotation periods P < 4 d. The analysis of the magnetic filling factors reveal two different patterns of either very smooth distribution or a more patchy one, which can be connected to the dynamo state of the stars and/or stellar mass. Conclusions. Our measurements extend the list of M dwarfs with strong surface magnetic fields. They also allow us to better constrain the interplay between the magnetic energy, stellar rotation, and underlying dynamo action. The high spectral resolution and observations at near-infrared wavelengths are the beneficial capabilities of the CARMENES instrument that allow us to address important questions about the stellar magnetism.

Abstract:

The survey ship would be interfered by wave-generated magnetic field in marine survey. The waves magnetic field is difficult to eliminate because it is the signal in low frequency like ships magnetization field. When survey ship sails, the frequency of waves magnetic field would change. It was found that the frequency has a linear relationship with ships speed and varies in sine or cosine with the angle between ships and waves directions. Ocean waves PSD would be compressed and strong noise of low frequency in narrowband turns up when ship sails in the same direction of waves. The frequency band of PSD would be broadened and small interference occurs while ships direction is opposite. A conclusion can be drawn that survey ship should sail reversely with ocean waves in marine magnetic survey, so the magnetic field induced by ocean waves would extend to high frequency and it is better for noise elimination.

Magnetic survey has been applied to detect underwater pipeline location, tracking and depth more and more nowadays. In order to detect such smaller targets, besides the application of high-precision magnetometer detector, an effective method especial for underwater pipeline is needed. This paper is to research the magnetic survey method for detecting the underwater pipeline. In terms of its magnetic anomaly characteristic, magnetic sensor array and magnetic anomaly gradient method which can eliminate geomagnetic diurnal variation are adopted to detect the location, tracking and depth of underwater pipeline. Finally, the experiment has shown that this method has good detection accuracy and value in engineering application.

Abstract:

The performance of both ground level and airborne magnetometer systems have been greatly improved as a result of advances in digital electronics, accurate automatic positioning devices and the introduction of high resolution, fast sampling caesium magnetometer sensors. Multiple sensor, low heading error airborne surveys are now being performed at relatively low ground clearance levels. The development of the TM-3, automatic positioning ground magnetometer system has made it practical to adequately sample all spatial frequencies present in the ground level magnetic field thereby acquiring the full spectrum of magnetic information.Approximately a one square kilometre area near Coolgardie in WA has been chosen as a case-study area for investigating the relative effectiveness of conventional and new, ground level and airborne, magnetic surveying techniques. The site is geologically typical of the auriferous environments within the Yilgarn block.This is the first time that such a comparative study has been made using all of the most common magnetic survey sampling standards available to the exploration industry. Data collected from conventional, government sponsored regional airborne survey and ground level proton precession magnetometer surveys has been image processed using state-of-the-art techniques. Data from a high quality, low level, multiple sensor, airborne, caesium magnetometer survey and a "broad spectrum" (sampled at a density of 200,000 measurements per square km) ground level caesium survey have similarly been processed. Geological control has been obtained from an extensive drilling and costeaning program.This data set has provided a definitive comparison in cost spent, speed of survey and information obtained from each survey.

Abstract:

AbstractIn this paper we present a few results from the first three years of an ongoing survey of globally-ordered magnetic fields in relatively faint (down to V ≈ 9) upper main sequence peculiar stars that we are conducting on the Dominion Astrophysical Observatory (DAO) Plaskett telescope. The DMFS uses the inexpensive DAO polarimeter module, dimaPol, mounted at the Cassegrain focus of the 1.8 m telescope to detect new magnetic stars and determine rotation periods and longitudinal magnetic field curves using medium-resolution (R ≈ 10,000) circular spectropolarimetry of both the Hβ line and metal lines in an approximately 280 Å wide wavelength region centered on Hβ. By concentrating on the mid-B to A-type peculiar stars, the DMFS provides an extension to the ‘Magnetism in Massive Stars’ (MIMES) Large Program which concentrated on similar field detections in more massive stars.

Full text

Abstract:

Cataclysmic Variables (CVs) are close binaries containing a white dwarf primary and a Rochelobe filling red dwarf secondary. In magnetic CVs (MCVs) the white dwarfs have magnetic fields that are sufficiently strong (106 – 108 Gauss) to direct the accretion flow onto the surface of the primary. MCVs are divided into the lower field intermediate polars (IPs) and the higher field polars. Typically, IPs have accretion disks that are disrupted in the center and magnetically channelled flow onto the poles. Polars are diskless, an accretion stream flowing from the inner Lagrangian point impacts directly onto one or both magnetic poles. In addition, polars tend to have white dwarfs which rotate in synchronism with the binary orbit, while IPs have white dwarfs which rotate faster than the binary period. There are a few rare exceptions to this characterization, such as the slightly asynchronous polars and the stream-fed IPs.

Abstract:

The Australian Bureau of Mineral Resources (BMR) is responsible for the National Airborne Magnetic Database. This data base consists of results from approximately 3 500 000 line‐km of regional survey flying carried out over 35 years, recording total magnetic intensity. The magnetic data base is one of the most important geophysical data bases for Australia and is used extensively by the minerals and petroleum exploration industries. First‐pass coverage of onshore Australia is aimed for completion in 1992. This coverage contains data from surveys with a wide range of specifications, resulting in a wide range of data quality; some of the areas covered by poorer quality data may be reflown later. For the most part, the intention has been to acquire data at a continuous ground clearance of 150 m and with a line spacing of 1500 m. However, over some sedimentary basins, the line spacing is in excess of 3200 m. New color and grey‐scale (image processed type) digital magnetic maps (pixel maps) are in preparation; these will supersede the 1976 digital magnetic map of Australia, which was gridded on a 1.2 minute mesh (2000 m) mostly by digitizing contours on maps. The new map, produced from flight‐line data, will have a grid size of 0.25 minutes. Initially, a series of maps will be produced with each one covering a block of 4 degrees latitude by 6 degrees longitude, coinciding with standard 1 : 1 000 000 map sheets. An example included for the Adelaide 1 : 1 000 000 map sheet in Southern Australia shows a dramatic increase in the number of anomalies over those that were evident in earlier contour presentations.

Abstract:

The use of drones in mining and geological exploration is under rapid development, especially in the field of magnetic field prospection. In part, this is related to the advantages presented for over ground surveys, allowing for high-density data acquisition with low loss of resolution, while being particularly useful in scenarios where vegetation, topography, and access are limiting factors. This work analyzes results of a drone magnetic survey acquired across the old mines of Don Jacobo, where Copper-Cobalt-Nickel stratabound mineralizations were exploited in the Estancias mountain range of the Betic Cordillera, Spain. The survey carried out used a vapor magnetometer installed on a Matrice 600 Pro Hexacopter. Twenty-four parallel survey lines were flown with a speed of 5 m/s, orthogonal to the regional strike of the geological structure, and mineralization with 50 m line separation and 20 m flight height over the ground was studied. The interpretation of the magnetic data allows us to reveal and model two high magnetic susceptibility bodies with residual magnetization, close to the old mines and surface mineral shows. These bodies could be related to potential unexploited mineralized areas whose formation may be related to a normal fault placed to the south of the survey area. Our geophysical survey provides essential data to improve the geological and mining potential of the area, allowing to design future research activities.

Abstract:

the three-component magnetic survey in well, as an important means in the geological prospecting, plays an important complementary role in geological magnetic survey data. During the data process of three-component magnetic survey, the drilling technology, instruments of three-component magnetic survey in well as well as performance and precision of the gyroscope inclinometer should be considered synthetically, and the appropriate data processing method should be selected according to the different trajectory feature of borehole, in order to improve the accuracy of data interpretation.
