Southland soils

Straight after we had vacuumed all chips' fragments and grass from the housewarming party out of the carpet on Sunday, we left on another fieldtrip with colleague and friend André (it takes only little fieldwork misery to become friends…). Instead of only 3 sites we had now planned optimistically for at least double that amount. Instead of North, we drove South. We passed Mount Aoraki/Cook in perfect visibility, and 7 hours later arrived in the town of Lumsden, where we were to stay in the Lumsden Hotel. Lumsden's motto is “this is as Lumsden as it gets”, and we can confirm that that is true, although not quite sure what it means…

This time the sites were much better accessible by car, which meant that we didn't have to lug heavy equipment up and down steep canyons. Instead, we could use all the labour intensive and equipment-rich techniques. This included the use of “black pearls” to estimate the volume of soil pits we dug in stony soils, and also the use of the insanely heavy soil corer in stone-free soils. So despite the lack of walking, it was still a physically active week, and I was pleasantly surprised on the last day that the heavy soil core hammerhead didn't feel heavy at all anymore. This is not to say that everything was easy and fun. For instance, we painstakingly dug 3 soil pits to 40 cm depth through large rocks while a hurricane was blowing away all equipment, and the wind direction changed constantly so that we always had soil blowing into our faces.

How not to use the soil corer, we had some initial difficulties to remember the method correctly...

 From Lumsden we moved to the Catlins into the Papatowai motel, where I stayed a long time ago on my first hard-core fieldwork trip in NZ. This time it was much more pleasant and we even had time to walk the estuary/beach and the wrong trail through the forest (had to walk back, barely made it through the estuary before high tide).

And finally we stayed in Beaumont, which kiwi's pronounce differently from the French, which confused us and the locals alike. 
 
We sampled 6 sites in 5 days, destroyed 1 soil corer, ate 4 out of 8 dips left over from the housewarming party, found out that rural NZ doesn't bake the best pizzas, and finished off with a textbook soil directly overlying schist parent material, so all in all another successful soil experience.

Unlike the upcoming trip with Thomas' parents, it was very easy for this trip to find accommodation spontaneously, so any future visitors coming over in the busy tourist season can expect to be taken to this very rural side of NZ that little tourists will know… Nice and quiet!
