Rathlin Island lies north of mainland Northern Ireland, a few miles offshore. I spent three lovely days there this past summer, investigating the geology and appreciating the wildlife (puffins and other sea birds, and seals). The geology is pretty straightforward: Paleogene basalt overlying Cretaceous “chalk” (really not so chalky here – technically, it’s the Ulster White Limestone). Here’s a suite of interactive imagery that you can use to explore Rathlin’s …

Mineral surfaces under the SEM: 6 new micro-GigaPans

As mentioned yesterday, my student Robin has been having some success lately in making GigaPan-scale imagery using the new desktop scanning electron microscope that our division acquired. They aren’t as super-high resolution as most of the other GigaPan images I post here, but they are very, very small – and thus expand the scope of our imaging initiative. Enjoy exploring: find cleavage planes, microscopic plumose structures, examples showing the constancy …

A suite of plankton S.E.M. micro-GigaPans

My student Robin has been working (on and off) for more than a year to figure out the best way to make GigaPan-scale imagery using the new desktop scanning electron microscope that our academic division acquired. There are several technical challenges to be overcome, each different, and some with ‘solutions’ that cause other problems. Dealing with all that takes time and has caused a lot of frustration. (We have a …
