Welcome to the fifth Daily Field Note! Here you find the top post of the day, one covering each scientific field that is included by Geopolis. Since these authors put a lot of effort in writing a good post they surely deserve the extra exposure.

Geopolis is a project to promote and connect authors who write in the fields of global sciences. Upvotes are currently worth more than $1,50 so don't hesitate to get involved! You can read more about the project and how to join here:

Anthropology: When Russia owned the West, a review of 'Glorious Misadventures'

@zest made place for a new author in Anthropolgy today! @plotbot2015 wrote an interesting article on the Russian expeditions and their influence on the environment. This is really worth the read and gives you an insight in a story you might not have came across otherwise.

Original post

In my review of Frontier I mentioned this book, which traces the history of the Russian American Company, which was their answer to Frontier's Hudson Bay Company or the British East India Company. They saw the Westerners getting rich off furs and gold, and they wanted a piece of that action. Or at least Nicolas Rezanov did. He tried for several years to make the right connections at court to get a corporate charter approved, and investment for ships, and condemned criminals to man them.

Geography: Google Earth pearls #7: The geography behind Champagne

Ever wondered what made Champain, "Champain"? Well, it's all in this post. Together with some nice satellite imagery and background stories you get to know about the history of the beveradge and its region thanks to @ignacepelckmans.

Original Post

Welcome in the Champagne region in France. What you can see in the middle, are the grape ranks which are the first step to the famous champagne whine. The other fields are regular Western European cropland where farmers produce wheat and other cereals. The difference in income from the two types of agriculture is huge and it's pretty interesting to see why. If you want to buy an hectare of agricultural land in the Champagne region, you pay over a million dollars for the an hectare of land, located on steep slopes and with a rather infertile soil. If you want to buy a piece of land with fertile, well developed soils which a gentle slope and overall pretty easy to cultivate, you would pay around 10 000 dollars. Pretty counter-intuitive, no?

Geology: The erosion process and the soil formation

@mirkon86 made a post on soil formation processes and does this in clear English and Italian as well!

Original Post

Erosion means the set of processes that occur through exogenous agents such as running waters, glaciers, wind and the sea and which produce new rock fragments, taking over the already degraded rock debris to transport them and deport them in different places. Taking an example of the glacial environment: a rock that breaks down by frost weathering, undergoes a subsequent erosion from the weather like the wind that slowly scratches the rock or rolls it from a slope, a glacier in motion that absorbs the block and slowly blunt during its movement... As you can see there are various possibilities that can give way to create erosion, but I can assure you that there are many others, in very different contexts. The final result of that rock, if its journey was very long, will be to become dust, or a beautiful rounded river pebble, which almost all of us have pulled at least once in our life (all this will depend a lot on the composition of that rock). But when we have maximum erosion, what happens?
