• Web-based resource for identification and classification of sedimentary components and lithologies in smear slide

• Funded by the University of Minnesota Interdisciplinary Informatics Seed Grant Program

Smear Slide Reference

1C

• No reference work exists• (Rothwell 1989 for

marine sediments is out of print and goes for $1000 on Amazon . . .)

• Need accurate sediment description: core data

Lacustrine Smear Slides

1C

• Free online resource• Useful to novices and

experts• For research and

education• Open for use in marine

and other communities• Main focus on mineral

components, polarizing light microscopy

• Also biological components, reflected light microscopy

• Projected to go live in early 2012
