Thermal drone observations capture fine‐scale population decline of short‐tailed shearwaters
Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 773-789, December 2025.Researchers used thermal drone technology to monitor short‐tailed shearwater colonies in Tasmania from 2019 to 2024, discovering a concerning 27% decline in chick numbers during this period. The study estimates that the global population of these seabirds has dropped dramatically by 41% since 1985, falling from 23 million to approximately 13.5 million ...

Validation of Regional Positioning Service User Connections as Support in Update Cartography
Transactions in GIS, Volume 29, Issue 1, February 2025.ABSTRACT The significant demand for highly updated geospatial or cartographic information surpasses the capacity of the official agencies responsible for its generation. The procedure for updating official cartography, in some Spanish regions, can take more than three or 4 years.

Pengaruh Lingkungan Pengamatan pada Ketelitian Horisontal GNSS dengan Metode RTK-NTRIP
Jurnal Nasional Pengelolaan Energi MigasZoom, 2020 The aim of this research is to empirically prove the influence of the observation environment on the horizontal accuracy of GNSS by the RTK-NTRIP method with an emphasis on various possible obstruction conditions and the length of time to achieve accuracy ≤5 cm.

Archaeological Prospection, Volume 32, Issue 1, Page 59-76, January/March 2025.ABSTRACT Underwater archaeology relies on expensive and time‐consuming invasive methods for identifying and excavating objects buried in the seabed or identifying layers in shallow and intertidal environments. Especially shallow and intertidal environments are challenging due to locally high levels of sedimentation that offer good conditions for ...

Spatial Distribution of Thaw Depth in Palsas Estimated From Optical Unoccupied Aerial Systems Data
Permafrost and Periglacial Processes, Volume 36, Issue 1, Page 22-36, January/March 2025.ABSTRACT Maximum seasonal thaw depth, referred to as active layer thickness (ALT), is one of the key parameters used to monitor permafrost conditions. ALT maps based on interpolation of point measurements or derived from coarse or moderate spatial resolution satellite data often hide small‐scale spatial variations in thaw depth resulting from ...

Paving the Way for Low‐Carbon Shipping Fuels in Long‐Haul Trade Routes
International Journal of Energy Research, Volume 2025, Issue 1, 2025.In 2023, the International Maritime Organization strengthened its ambition, aiming at net‐zero greenhouse gas (GHG) emissions by 2050. This goal depends on the replacement of oil‐derived fuels by alternative fuels and motorizations that bring the risk of technological lock‐in and increasing global trade costs. The establishment of low‐carbon (LC) trade

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances
Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...
