For those who didn\u2019t join us last time, the Urban Tides Community Science Initiative unites coastal researchers and the public through photos. Any person can download the app on their phone or access the database through their computer and upload a photo of the coast whenever they are beachside. These photos give researchers like Dr. Sarah Giddings at Scripps Institution of Oceanography the ability to create and check models that provide insight into the effects of extreme tidal events, storms, sea level rise, and urban runoff. These events can lead to local flooding, sediment movement and erosion, and damage to infrastructure. Urban Tides beach walks are held to give people the chance to dive deeper into these issues and the opportunity to see these effects in person.<\/p>\n

This time around, the beach walk was held at Torrey Pines State Reserve in San Diego. In terms of seeing examples of coastal erosion, Torrey Pines is a gold mine. Crumbling bluffs to the north and south, morphing Los Pe\u00f1asquitos Lagoon to the north, a deteriorating concrete parking lot to the west, and virtually no beach sand left, only cobbles!<\/p>\n

At 3:30 on March 5th, we met at the reserve facility and USC Sea Grant\u2019s Linda Chilton gave a great overview of Urban Tides and how to use the mobile app to take photos and share data. With her were flood maps, useful depictions of where in San Diego would flood in a 50-year and 100-year storm event. We then moved north, and along the way, we noticed large chunks of concrete were missing from the parking lot, as if something had taken bites out of it! Something did: the ocean, as a combination of high tidal energy, storms, waves, and warm water temperatures (contributing to sea level rise) carved out the soil underneath the concrete and weakened the integrity of the road.<\/p>\n

We were also lucky to have SIO PhD student Madeleine Harvey on board this walk who studies Los Pe\u00f1asquitos Lagoon. This lagoon regularly changes its morphology, as sediment in the shallow waters can drastically move in a single day. Over the past couple weeks, the mouth of the lagoon became completely blocked by cobbles, cutting off the estuary from the ocean. The amount of sediment deposited was so much, a handrail that leads from the lot to the beach was practically buried! As such, State Parks intervened, bringing in bulldozers to clear the entryway. Unfortunately, large waves closed the lagoon again only a day after our walk!<\/p>\n

Again, I asked the participants to complete a pre and post-survey to learn more about them and their motives for engaging in the initiative. Combined with the responses from the previous beach walk as well as responses collected from the online photo database, I\u2019ve analyzed why people participate. It\u2019s incredibly inspiring, as over 50% of participants attended to learn about local El Ni\u00f1o impacts and sea level rise, and 38% of participants wanted to learn information to share. It\u2019s good to know that Urban Tides is fulfilling this educational role in the community, and that people are actually (statistically tested) walking away with new knowledge that can be shared.<\/p>\n

\"\"<\/p>\n

However, there is still room to grow, and keeping participants involved is the next step for Urban Tides. Events like the beach walk were a hit, but project updates from scientists seem to be most in demand. We\u2019ve gotten word from Dr. Andy O\u2019Neill at U.S. Geological Survey that they\u2019ve been able to pull data from the photos, so keep an eye out for those results!<\/p>\n

It is truly remarkable to witness what the community can do: given the proper guidance and training, citizen scientists can unite into a formidable force that propels research and science. As an emerging field, it is key to learn from other existing programs, and the upcoming nationwide Citizen Science Day on April 16, 2016, is a perfect time to learn about this and other local opportunities. There is nothing more inspiring than seeing
\nregular citizens transform into citizen scientists, and I\u2019m incredibly grateful to witness it firsthand. Experience it for yourself, and join the initiative!<\/p>\n\n\n\n<\/div>\n\n\n <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":74,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[49],"tags":[50],"class_list":["post-5857","post","type-post","status-publish","format-standard","hentry","category-student-blog","tag-studentblog"],"acf":[],"yoast_head":"\nWalking North: Lessons in Citizen Science<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/dornsife.usc.edu\/uscseagrant\/2016\/03\/15\/walking-north-lessons-in-citizen-science\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Walking North: Lessons in Citizen Science -
