©2020 Biological and Chemical Oceanography Data Management Office.Collected California and Bay mussel particle image velocimetry data within a water flume set to flow conditions between 1 and 4 inches per second. Movies are approximately 20 seconds long. California mussels were imaged on July 2, 2021 and Bay mussels were imaged on June 29, 2021. Due to the warm water the Bay mussels began spawning in the videos.

Collected 1 California and Bay mussel PIV dataset. Images were collected on a Nikon D7000 DSLR camera. A 325 mW diode-pumped solid-state laser (Laserglow Technologies® Hercules Series) was used for particle image velocimetry measurements. Movies were collected at 30 frames per second.
Individual .tif images are of a 1 cm by 1 cm grid that is used for a scale to size the images from pixel to distance.
One .tif image was collected for the Bay mussel and one .tif image was collected for the California mussel.
The Data File "mussel_PIV_and_spawning.zip" contains the .tif scale images and the following .MOV movies:

Instrument usage description:
Measurements of flow over the mussels were obtained using a custom-built particle image velocimetry (PIV) experimental setup. A 325 mW diode-pumped solid-state laser (Laserglow Technologies® Hercules Series) was positioned centrally on a platform clamped to the top of the water tunnel test section. The continuous wave laser produced a 532 nm wavelength green light, which was directed vertically downward through a pair of convex lenses to produce a 2-dimensional laser sheet measuring approximately 10 cm by 10 cm. Perpendicular to the laser sheet and level with the coral models, a digital single-lens reflex (DSLR) camera (Nikon Corporation® D7000) with a 24-85mm macro lens was mounted on a tripod.
