Today I finished processing the 20th sample population of sand crabs and put together a small graph to share.
The sample sites are listed from North to South along the California coast. Each bar represents a percentage of the sample population collected that was found to have ingested microparticles. Of the 20 sample populations, two did not have any micro particle ingestion, however the other 18 sample populations had sand crabs that ingested microparticles. Each sand crab found to have microparticles was photographed and recorded. I am interested to see how the rest of my samples look and plan to have a more complete set of results in the next 2-3 weeks.
