Dig Sand Crabs? Join Our Citizen Scientist Squad
Nov. 19, 2015 — This blog was written by Taylor Spesak, Public Programs Intern, and Catherine Hoffman, Programs Coordinator, at our Santa Monica Pier Aquarium.
Beneath your toes at the beach are thousands of sand crabs just trying to make it through the day. Most beachgoers walk right over them without a care, but Santa Monica Pier Aquarium citizen scientists are eager to find them!
Heal the Bay recently partnered with the statewide LiMPETS program to bring sand crab monitoring to the Santa Monica shoreline just outside the Aquarium’s doors. This program activates people along the entire California coast to do real science through hands-on data collection.
But…why do we care about sand crabs? For starters, they can tell scientists a lot about the sandy beach ecosystem. For example, if there is a low number of crabs during a collection, water quality may be poor or a high number of predators may be snacking on the sand crabs. The list could go on and on. By simply counting these overlooked creatures, scientists can make conclusions about the entire ecosystem’s overall health.
Citizen scientists from the Aquarium are focusing on sand crabs specifically in the area around the Santa Monica Pier. We’re examining several factors that may be affecting the number of crabs present, like how long it’s been since a heavy rain and whether the sample spot is under the Pier. We’ve already noticed that there seem to be more crabs during dry spells and more crabs directly under the Pier.
The findings are intriguing, and we look forward to analyzing more data. That’s where you come in!
Experienced or not, anyone can be a citizen scientist, and we’d love to do science with you. As long as the tides are low, the surf isn’t too aggressive, and there is no rain we will be out collecting data every Wednesday at 3:00pm. No training required! Meet us at the Aquarium and we’ll then head down to the beach to collect our sand crabs. This program can also be used as a service or linked learning opportunity for middle and high school students. An AP Environmental Studies class from Los Angeles Academy of Arts and Enterprise has already helped us collect great data.
So come get crabby with us on Wednesday, November 25, at 3pm and kick off your citizen science career under the Pier!
