|Abstract:||This report documents the instrumentation, test methods, results and analysis used to assess the likelihood of brain injury to a sea lion as a result of a head impact with a sea lion exclusion device (SLED) stainless steel grid. The testing used a validated method for measuring head impact injury in human pedestrians and was then subsequently scaled and extrapolated with consideration of the head and brain mass of the New Zealand sea lion. The results of the tests are used as the basis of a graphical method for determining a range of the likelihood of a brain injury, based on swim speed and effective sea lion head mass, for particular impact locations. The results indicate that an impact with the grid may induce some sort of brain injury in sea lions; the risk of life-threatening brain injury to a female sea lion in a 10 m/s collision with the SLED grid at the stiffest location tested may be higher than 85%. Although some assumptions were made to arrive at the results, this report provides base-line results for the impact characteristics for the current grid design. This will allow a baseline for the assessment of future grid modifications.|
