For those interested in getting a sense of how NOAA provides critical support in the management of a challenging and complex disaster situation, click through the article. There is a short and interesting article and video describing how both sonar and lidar are used to measure water depth, the air gap between the water and the remaining bridge and more.

With two real-world maritime crises now unfolding, it is becoming clear that the Marine Corps has adapted appropriately to modern challenges and that it is still the capable crisis response force that the nation has come to rely on. Not everyone agrees.

ArcGIS Solutions June 2024 Release Sneak Peek #9: Weather Operational Effects Weather, terrain, and time constitute the basic environmental setting for all military operations. Favorable, and unfavorable, conditions can drastically impact the overall effectiveness of an operation and pose risks to both personnel and equipment.   If you are a geospatial specialist, or intelligence officer, who wants to understand the impact of weather on planned military operations, we believe the Weather Operational Effects solution will help.   Weather Operational Effects will help defense agencies understand weather conditions within an area of responsibility, analyze potential operational effects of weather, and share information with staff and leadership. #arcgissolutions #sneakpeek #esri #arcgis #militaryintelligence #defense #allsource

In case you missed how important this is

The disaster of the British airship R 101 prompted the Zeppelin Company to reconsider the use of hydrogen, therefore scrapping the LZ 128 in favour of a new airship designed for helium, the LZ 129. Hindenburg had a duralumin structure, incorporating 15 Ferris wheel-like main ring bulkheads along its length, with 16 cotton gas bags fitted between them. The bulkheads were braced to each other by longitudinal girders placed around their circumferences. The airship's outer skin was of cotton doped with a mixture of reflective materials intended to protect the gas bags within from radiation, both ultraviolet (which would damage them) and infrared (which might cause them to overheat). The gas cells were made by a new method pioneered by Goodyear using multiple layers of gelatinized latex. In 1931 the Zeppelin Company purchased 5,000 kg (11,000 lb) of duralumin salvaged from the wreckage of the October 1930 crash of the British airship R101. Hindenburg's interior furnishings were designed by Fritz August Breuhaus, whose design experience included Pullman coaches, ocean liners, and warships of the German Navy. Helium was initially selected for the lifting gas because it was the safest to use in airships, as it is not flammable. One proposed measure to save helium was to make double-gas cells for 14 of the 16 gas cells; an inner hydrogen cell would be protected by an outer cell filled with helium. At the time, however, helium was also relatively rare and extremely expensive as the gas was available in industrial quantities only from distillation plants at certain oil fields in the United States. Hydrogen, by comparison, could be cheaply produced by any industrialized nation and being lighter than helium also provided more lift. Because of its expense and rarity, American rigid airships using helium were forced to conserve the gas at all costs and this hampered their operation. Despite a U.S. ban on the export of helium under the Helium Control Act of 1927, the Germans designed the airship to use the far safer gas in the belief that they could convince the U.S. government to license its export. When the designers learned that the National Munitions Control Board refused to lift the export ban, they were forced to re-engineer Hindenburg to use flammable hydrogen gas, which was the only alternative lighter-than-air gas that could provide sufficient lift. One of the side benefits of being forced to utilize the flammable yet lighter hydrogen was that more passenger cabins could be added.
