A novel approach leveraging spatial autocorrelation and advanced statistical modeling in R successfully mapped wind patterns across Sri Lanka, particularly in the Central Highlands. By analyzing 23 irregularly distributed wind measurement stations with diurnal data from 2015, the study identified seasonal variations and diurnal changes in wind speed and direction, including significant coastal and highland dynamics. The use of semi-variograms—spherical and exponential models—and Ordinary Kriging enabled precise spatial interpolation, generating 48 weekly wind maps that pinpoint potential wind farming areas. This method not only advances wind energy resource planning but also demonstrates R's capability for analyzing complex geographic phenomena with high uncertainty.

A study of the Venus House mosaics at Volubilis reveals that the deterioration of these Roman mosaics is directly linked to the settling and heaving of concrete slabs beneath them. Using advanced techniques—laser level surveys, UAV-based photogrammetry, and ground-penetrating radar (GPR)—researchers identified void spaces under the floors, slab instability, and potential rebar corrosion, all contributing to visible surface damage. These findings underscore the need for restoration efforts that address not just the mosaic tesserae but the entire structural layer, ensuring long-term preservation of this significant archaeological site.

Research reveals that the Western Hemisphere Warm Pool (WHWP-EP), the second warmest body of water on Earth, significantly impacts marine protected areas (MPAs) in the Mexican Pacific. Using satellite-derived data from the Advanced Very High Resolution Radiometer, scientists analyzed its interannual spatial variability and assessed the response of chlorophyll a (Chla) as a proxy for phytoplankton in MPAs. The study found that most MPAs experienced a negative response to warm events, particularly those in the Deep Mexican Pacific and southern Gulf of California, while the Midriff islands area showed resilience due to its higher tolerance to warm conditions. These findings underscore the need to incorporate phytoplankton dynamics into marine planning and management strategies, especially in areas like the Deep Mexican Pacific where MPAs have shown limited effectiveness.
