    Historical reconstruction of sea urchin grazing events in Aleutian Island ecosystem from grazing scars, 1965-2004
    (Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2019-02-25) Steneck, Robert S. ; Estes, James ; Rasher, Douglas B.
    Historical reconstruction of sea urchin grazing events in the ecosystem, achieved via enumerating the annual frequency of grazing scars that are archived in the calcified matrix of Clathromorphum nereostratum. Intact colonies of C. nereostratum were collected via SCUBA. Reconstructions were performed on polished and imaged sample cross-sections.
