CWT was applied for lithology detection over the Costa Rica margin, using gamma ray logs as a best indicator. It is observed that four major sedimentary layers terminated there with a gabbroic sill. DWT was applied on density logs to identify small changes in the rock matrix. Accordingly, wavelet-based fractal analysis was applied on every sedimentary layer. This analysis indicates that a certain portion of wells contain abundant shale and low-energy environments. Hide

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.

To provide reliable time series of evapotranspiration, we evaluated the performances of four different gap-filling methods when tailored to conditions of hilly crop fields. The tailoring consisted of splitting the time series beforehand on the basis of upslope and downslope winds. The obtained accuracies on evapotranspiration after gap filling were comparable to those previously reported over flat and mountainous terrains, and they were better with the most widely used gap-filling method.

The authors have successfully recommissioned an unused tri-axial Helmholtz coil system. The system now serves as a national facility for calibrating magnetometers. Hide

The presence of magnetic fields in space dominate the way planets interact with different types of plasmas. Thus, measuring them is extremely important when studying space. We present an instrument capable of measuring magnetic fields at a fraction of the cost, power and size of traditional magnetometers. With this technology, a science-grade magnetometer for small satellites can be achieved, enabling the study of the space environment with large clusters of sensors in future missions. Hide

The paper presents the first results of ground penetrating radar investigation in the church in Kłodzko, Poland. The research was part of SEG Field Camp, which was organized by SEG Student Chapter Cracow and SEG Bucharest Student Chapter. The aim was to verify the presence of possible underground structures. Among the most important discoveries are previously unknown crypts. Results of the research might be helpful for future archeological excavations and other investigations in the church. Hide
