Surveying Lake Titicaca [2024]
--
hydro-international.com/conten <-- shared technical article
--
[A very comprehensive hydrographic and shallow geophysical study and mapping effort of Lake Titicaca…]
“In October 2024, officers from the Category “A” Specialization Programme in Hydrography for Naval Officers of the Peruvian Navy conducted their complex multidisciplinary field project at Lake Titicaca at Puno in Peru, which is the highest navigable lake in the world (3,800 metres above sea level). The purpose of this survey was to address issues in the lacustrine environment due to hydrological processes that have occurred in recent years in this water body.…”

[as a ‘colonial’ myself (New Zealand), I have a fascination with this sort of history – and throw in some early-ish survey and national cartography not long after Cyprus was ceded by the Ottomans…]

🌊🚁 Measuring river discharge during #floods is risky. Discover how Jennifer Guohong Duan, Ammon Cadogan, and @sandcountyfrank used drones to safely gather flow velocity and discharge data from flooding rivers. Explore their innovative approach at doi.org/10.25422/azu.data.2111 and doi.org/10.1061/JHEND8.HYENG-1. Image: Duan et al.

How Earth Would Look If All The Ice Melted [global video simulation]
--
youtu.be/VbiRNT_gWUQ?si=M5J3l9 <-- shared video simulation
--
“We learned last year that many of the effects of climate change are irreversible. Sea levels have been rising at a greater rate year after year, and the Intergovernmental Panel on Climate Change estimates they could rise by another meter or more by the end of this century.
As National Geographic showed us in 2013, sea levels would rise by 216 feet if all the land ice on the planet were to melt. This would dramatically reshape the continents and drown many of the world's major cities…”
