'Yes, yes, definitely the right spot. You see that hill over there? Yeah that will probably give us some great bacteria to work with.' The spots I sampled were predefined, but not so precisely that you couldn't 'play with them' a little. In order to get really dry and really wet samples I looked up good area's using weather data and combined them with previously sampled areas (pastures used in previous research) to combine data and enrich both research.
However you can always go just a few pastures closer to the beach or just a bit more over that hill to give you a great view as well as a good sampling spot. Part of the sampling was taking pictures of the soil to see what vegetation is located there (a lot of just a few clover plants). Now don't you agree that this soil just looks fantastic?
