Portable aerial spore collecting system by the Department of Plant Pathology, North Dakota State University.
Members of the research team designed and built a spore sampler that was lifted to various heights by a tethered helium balloon from Mobile Airships.
Sampling was possible in remote areas including fields during harvest.
The unique portability allowed this collecting system to be utilized almost anywhere. The balloon was transported in the back of a full-sized pickup truck. Tests showed that the balloon could be operated at heights up to 150 Ft. and in winds up to 10 mph, for up to 6 hours per day.
