    • Razor clam density estimates 1998 and 2019 in Hallo Bay, Alaska

    Metadata Updated: October 23, 2025

    The data were collected to estimate Pacific razor clam density in the region of Hallo Bay, Alaska in Katmai National Park and Preserve. The region was originally sampled in the 1970's (Kaiser, R.J., Konigsberg, D., 1977. Razor clam (Siliqua patula Dixon) distribution and population assessment study. Alaska Department of Fish and Game. 78 pages). Tom Smith with USGS resampled Hallo Bay plots in 1998 and 1999 and the NPS, lead by Heather Coletti, revisited a subset of Smith's plots in 2019. Plots were sampled using the same methodology across all three time-periods and estimates were used to assess declines in densities over time.
