US CONUS Rivers Of Dimension By Annual Flow – An Older (2013) But Still SO Useful Hydrologic Visualisation
--
https://pacinst.org/american-rivers-a-graphic/ <-- shared technical post

“... Several things stand out:
1) the massive flow of the mighty Mississippi and Columbia River systems
2) the paucity of major rivers in the western US, especially the southwestern US, where the only major rivers are the seriously over-tapped Colorado and Rio Grande Rivers
3) the local importance of the Sacramento-San Joaquin Rivers in California, which serve the state’s cities and agricultural regions…”

Small Waterbodies Of Large Conservation Concern - Towards An Integrated Approach To More Accurately Measuring Surface Water Dynamics
--
https://doi.org/10.1016/j.ecolind.2025.113525 <-- shared paper
--
“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.

Bus Pirate 5 REV10 includes a "carbon fiber" button cap. Caps are primed, pushed through printed PVA foil floating in water, and sealed for durability. Dip dye is typically used to customize helmets, car parts, and sneakers.

Check out Boss dip caps in a suit and gold watch! Photos in next post.
