Quantifying relationships between rock hardness, shore platform topography, and intertidal biota: Oregon Coast
College of Arts & Sciences

To test the link between rock hardness and meter-scale shore platform morphology and the link between rock hardness and biodiversity, we examined six locations on the Oregon Coast, USA with varying rock types. At each site, we collected rock hardness data along a transect using a Schmidt hammer. To quantify topography, we processed hand-held photographs of each site using structure-from-motion photogrammetry in Agisoft PhotoScan, calculating surface roughness and related statistics in CloudCompare. Our preliminary results confirm that sites with softer rocks tend to have smoother shore platforms and higher levels of biodiversity.
