Four days ago, we began a two day sampling event. First, one of our automatic samplers jammed and we lost all our samples. This morning, we found our sampler precariously hanging from a cliff, held by a chain to a car battery and a small acacia tree. All our samples but two had poured out. No word yet on whether a hippo or just a large branch floating by were responsible. Just grateful nothing was broken. Starting again today... maybe tomorrow it will work?
