Helicopter sling load at Lake Bonney in Antarctica
Thanks for posting. I work with Kings River Watershed Partnership and our river is on the 303 D list for TDS impairment. I like your Cat Paw model, I think I'll try to use the idea to explain how these ions work
Thank you for another sterling video. As a Naturalist and Environmentalist, I am alway coming up against a lot of folks who know of a lakes surface, and maybe a bit of fish, but no knowledge on how an aquatic system works. The result is that often the lakes and pond are rendered dead (particularly in the eastern part of the state) before the ring of home owners knew what was happening, due to mismanagement and the desire to make the pond/lake "clear".
Welcome back. Your video presentations on a most vital topic were missed. I hope your efforts are primarily for a student audience, yet I am very glad to watch a well explained, thorough lecture on aspects of fresh water/ salt water systems.
Just warm hello to pet lovers from cat lover channel!
You look and sound like Elle Cordova
So beautiful ❤
cool!
Unreal! Are you sampling?
