Revised Level A Data Collection

NOAA Fisheries created a series of forms that collect valuable stranding information through a process known as Level A data collection. Stranding network responders use these forms to collect basic information on stranding events as well as morphology, life history, biology and general health. Scientists and natural resource managers use the information in these forms to help promote the conservation of marine mammal species, as well as to respond to and mitigate threats to marine mammal populations.

Level A data collection requires the following forms and guide:

  1. Marine Mammal Stranding Report - Level A Data [pdf]
  2. Marine Mammal Rehabilitation Disposition  [pdf]
  3. Marine Mammal Human Interaction [pdf]
  4. Examiners Guide [pdf]

What Kinds of Data Do These Forms Collect?

The Marine Mammal Stranding Report – Level A Data form asks basic questions about the stranding event, and the Marine Mammal Rehabilitation Disposition Report collects data on animals that are admitted to a rehabilitation center. Both forms were recently revised to ensure that the data collected help answer questions about important marine mammal issues. The Marine Mammal Human Interaction Report was recently created and will gather more detailed data on how humans affect marine mammal populations.

When Should These Forms Be Completed?

Stranding network responders complete the Marine Mammal Stranding Report–Level A Data form for every stranding event; the Examiners Guide provides a detailed description of all events requiring this form. The Marine Mammal Rehabilitation Disposition Report is completed for every animal that is transferred to a rehabilitation center. Finally, the Marine Mammal Human Interaction Report should be completed for every animal that requires the Marine Mammal Stranding Report–Level A Data form and is Condition Code 1 (alive), 2 (fresh dead), or 3 (moderately decomposed).


If you have any questions or concerns about filling out these forms, please contact your regional stranding coordinator. The new and revised forms are currently being programmed into the National Stranding Database, so that our network partners can directly upload data for the revised Level A data collection.

How Can I Access Data Collected on These Forms?

Access to the National Stranding Database is limited to active participants in the National Stranding Network. Members of the public can submit a data request to obtain data from the national database.
