Tissue Bank Data
The National Marine Mammal Tissue Bank (NMMTB) system website is now available:

In 1989, the National Marine Fisheries Service, Office of Protected Resources, in collaboration with the National Institute of Standards and Technology(NIST) began the National Marine Mammal Tissue Bank (NMMTB) for long-term cryogenic archival of selected marine mammal tissues. In 1992, the NMMTB was formally established by the Marine Mammal Health and Stranding Response Act (Public Law 102-587).

The NMMTB, which is an important component of NOAA Fisheries's Marine Mammal Health and Stranding Response Program, is maintained by NIST as part of the National Biomonitoring Specimen Bank and the Marine Environmental Specimen Bank, which was established in 2002.

Specimens from Alaska are provided to the bank through the Alaska Marine Mammal Tissue Archival Project. The USGS Biological Resources Division is the lead agency for this project.

The cryogenic banking facilities for the NMMTB are operated by the NIST Chemical Science and Technology Laboratory in Gaithersburg, Maryland, and Charleston, South Carolina. The Charleston facility is located in the newly-constructed Hollings Marine Laboratory at the South Carolina Marine Resources Center.

Protocols developed by NIST for collecting and archiving tissues are designed to:

  1. provide sufficient material for multiple analyses
  2. minimize the possibility of sample change and/or loss during storage
  3. minimize inadvertent contamination during sample handling and ensure sample integrity
  4. provide for long-term sample stability through cryogenic techniques
  5. track and maintain a record of sample history. Sources of tissues include
    • freshly-dead stranded animals
    • incidental takes in fishing activities
    • animals taken by Native Americans for subsistence

Indicator species include:

The NMMTB also has samples from other species.

Current partners for collections include:
