October
Event type: Project
Location: Laguna Beach, CA , United States
Contact: Chris Hart, hartdivers@gmail.com
Event website: https://www.facebook.com/groups/OrangeCountyUnderwaterExplorers/
Date: October 1, 2025 to October 31, 2026
Description: The Orange County Underwater Explorers (OCUE) are launching a Project Baseline effort beginning at Shaw’s Cove in Laguna Beach, California. This project will establish a one-year ecological baseline of local marine life and conditions, with the long-term goal of expanding to neighboring coves along the Laguna coast.
Divers will document broad flora and fauna using underwater photography, videography, and written observations. Supporting abiotic data—including visibility, temperature, and tide state—will be recorded during each dive.
A dedicated mapping team will use GPS buoys and acoustic pingers to chart key waypoints and create a diver-friendly navigation map of the site.
All data will be compiled in a central repository for long-term comparison.
Results will be shared through the GUE Project Portal, highlighted in Quest Magazine, and prepared for peer-reviewed publication. The dataset will also be structured to contribute to global repositories such as GBIF and OBIS.
This is a community science initiative designed to involve local divers, strengthen connections with conservation groups and universities, and provide actionable insights into the health of Laguna’s nearshore ecosystems.
