Aquatic Biogeochemist (bī ō gē ō kəm ist): My favorite science experience was hiking along the Waipi‘o Valley rim in the cloud forest to collect samples from the streams dropping into the valley. I lay in the streambed on my stomach and looked over the waterfall cliff into the valley below (hundreds of feet). It was breathtaking. The stream was also beautiful. It was a blackwater stream and the water looked like concentrated iced tea. The streambank was lined with brilliant green moss and the riparian forest was comprised of pygmy ohia trees. This stream is one of the prettiest I have ever seen. Photo by Mike Gomes.
