🤔What if researchers, policymakers, students, and the public could see all the monitoring programs along the California coast, and the parameters they sample, at a glance? What if they could better understand who is collecting data that can be used to manage, conserve, and study California's water resources, and where these programs operate?
Ten recently graduated UCLA Environmental Science students set out to make that happen, using three key questions as their guide:
1️⃣ What ongoing ocean and coastal monitoring programs operate within 11.6 nautical miles (13.4 miles) of the California coast?
2️⃣ What parameters does each program monitor, and what are its spatial coverage, sampling frequency, and monitoring platforms?
3️⃣ Where do spatial, temporal, and monitoring parameter gaps and overlaps exist within the 11.6-nautical-mile coastal buffer?
The result is the California Ocean & Coastal Monitoring Inventory, an interactive geographic information system map that can be searched by research program, the parameters it collects, and its geospatial coverage over time.
California's coastal monitoring programs include California Cooperative Oceanic Fisheries Investigations (CalCOFI), long-term ecological research programs, wastewater discharge centers, marine protected areas, power plants, beach bacterial monitoring initiatives and many more.
The inventory identified both key strengths and gaps in California's coastal monitoring infrastructure, as well as where efforts to close monitoring gaps could have the greatest impact on human and ecosystem health, fisheries, climate understanding, and the management of our ocean resources.
