These eight images from nature (planktic foraminifera, squid, copepod, diatom, shark tooth, snowflake, giant clam, nudibranch) are examples of just a few of the many and varied sample types that UCSC SiL has analyzed in support of research by UCSC scientists and researchers from around the world. We support the research of geologists, ecologists, oceanographers, biologists, environmental scientists, physical anthropologists, planetary scientists, as well as researchers from any other natural history or physical science discipline with stable isotope applications.
