“…For corroboration or expansion upon previous outcrop-based studies, this system requires workers to visit the locality themselves. Instead, open access to standardized petrographic image collections will allow broader groups of researchers to measure and interpret features in rock formations from around the world, enhancing both reproducibility (Baker, 2016) and diversity, equity, and inclusion (Fernandes et al, 2020) in geology. Although our archives are not continuous records like IODP cores, they benefit from the added spatial context available at rock outcrops and provide a zoomed-in perspective to supplement constantly improving aerial survey techniques (Shah et al, 2021).…”

Accurately assessing the shape, size, and modality of features in rock samples is a longstanding problem in geology. Recent advances in machine learning have introduced the possibility of performing these tasks through automated image analysis. To leverage these methods for geological and paleontological applications, we first need a way to acquire high-resolution images of polished slabs and thin sections with a field of view large enough to fit samples containing crystals, fossils, bedforms, etc. We describe a new multispectral setup that can acquire images at ~3.76 mm per pixel spatial resolution over a 21 cm 2 field of view, equipped with 8-band (470-940 nm) spectral resolution, plus a band for ultraviolet (365 nm) fluorescence. Additionally, we present a 5-band (470-940 nm) light table with automated rotating polarizers, which allows use of the camera as a high-throughput transmitted light thin section imager. The use of color bands outside the visible spectrum, as well as the registration of multiple cross-polarized rotations, encode rock properties that heighten image contrast and improve the accuracy of machine learning models. Our setup and methods provide an efficient way to (1) build reproducible image archives of rock specimens to complement field observations, (2) classify and segment those images, and (3) quantitatively compare lithofacies and fossil assemblages.

This supplement is intended to show our multispectral setup in more detail and explain how we mitigate chromatic aberration. We include a figure with annotated computer-aided design renderings of our transmitted and reflected light setups, and details for our light emission spectra. The text begins with background on the problem of chromatic aberration, details our experimental setup and blur modeling calculations, and discusses our final results.

“…Like other organizations, the BSG has developed a Meetings Code of Conduct and a Professional Ethics Policy to deter any harassment, bullying and discrimination, but there may be other actions that can be taken to further engender a welcoming, inclusive culture in geomorphology (cf. Fernandes et al, 2020).…”

Within and beyond academia, debates around equality, diversity and inclusion (EDI) have been gathering pace. We focus on EDI and geomorphology and address four main questions: (1) why does EDI matter for geomorphology?; (2) what are the barriers to greater EDI in geomorphology?; (3) how can we address these EDI barriers?; (4) can we ensure a resilient future for geomorphology by addressing EDI? At a time of critical environmental, social and economic transition, we contend that addressing EDI is essential for ensuring a resilient geomorphology, defined here as a discipline that is seen to be adapting to these changing external circumstances so that it remains relevant, vibrant and accessible to a wide cross‐section of society. Not doing so will limit the intellectual development of geomorphology, incur reputational risk for geomorphological groups and organizations like the British Society for Geomorphology, and ensure that the many potential benefits of geomorphology for science and society remain underutilized at best. © 2020 John Wiley & Sons, Ltd.
