This paper presents a fast and efficient large-scale anisotropic inversion technique for towed streamer electromagnetic (EM) data, which incorporates seismic constraints. The inversion algorithm is based on the 3D contraction integral equation method

In October 2012 a series of known oil & gas fields in the North Sea were surveyed with the newly developed towed streamer EM system. This is the first commercial Controlled Source EM (CSEM) system ...

To realize the full potential of a geophysical data set, and resolve interpretation ambiguities, the data must be integrated with other geological and complementary geophysical data. Seismic velocity and electrical resistivity are rock properties tha

The Earth’s lithosphere and mantle respond to Space Weather through time-varying, depth-dependent induced magnetic and electric fields. Understanding the properties of these electromagnetic fields is a key consideration in modelling the hazard to t

Summary The measured Towed Streamer EM data from a survey in the Barents Sea, undertaken in the Norwegian sector are inverted as a series of unconstrained and seismically guided 2.5D inversions. The subsurface geology is complex and provides a good t

Magnetotelluric (MT) data, in the form of MT tensors, are used to estimate directly the size and spatial distribution of the electric field in northern England and southern Scotland with the aim of predicting the flow of geomagnetically induced curre

Browning index, degree of browning, total phenolics content and polyphenoloxidase (PPO) activity of three carrot cultivars—Kendo, Ricardo and Stefano—were studied on a simulated market shelf (20 ◦ C) and during cold storage (4 ◦ C). There was
