“HIGHLIGHTS
• Hydrologic models were used to assess remotely sensed surface water estimates.
• The accuracy of satellite surface water estimates diminished for waterbodies < 2 ha.
• Vegetation reduces accuracy of surface water detection, especially during wet years..."

#Ireland has been elected to the #IALA Council at its inaugural General Assembly in #Singapore on 20 February 2025, following ratification of the IALA Convention in 2023. Represented by Yvonne Shields O'Connor, Ireland will influence global maritime navigation standards, focusing on marine aids, digitalisation, climate adaptation, and safety.

Minister for #Transport, Darragh O'Brien, highlighted Ireland's leadership in maritime safety and commitment to working with IALA to enhance global security and sustainability at sea. Ireland's priorities include addressing climate change impacts, maritime communications, and collaborating with the International #Hydrographic Organisation. The country's 2025-2030 strategy aligns with IALA’s mission to drive innovation and sustainability in maritime operations.

The Oldest Three-Dimensional Map in the World Discovered in a Paleolithic Cave Near Paris

French scientists have identified a unique engraving in the Ségognole 3 cave, located in the famous sandstone massif south of Paris. This engraving, dating back to the Upper Paleolithic, could be the oldest three-dimensional map ever found. The research, published in the Oxford Journal of Archae
