The Pacific Rocky Intertidal Monitoring Program is a product of over three decades of research at more than 200 rocky intertidal monitoring sites ranging from Southeast Alaska to Mexico. A research project of this magnitude is possible solely through the cooperation of a large consortium of research groups working together to collect compatible data that are entered into a centralized database. Special recognition should go to three agencies who have provided the majority of continuous funding for the project over several decades: Bureau of Ocean Energy Management, Partnership for Interdisciplinary Studies of Coastal Oceans and The National Park Service.

The synthesis of this research has resulted in the Pacific Rocky Intertidal Monitoring Program website—a summary of data, methods, and products of this research, with interactive mapping and graphing features.

Extensive efforts have been made to ensure that online data are accurate and up to date; however because of the magnitude of this Program, some errors may have been missed. Before using these data for analysis or presentation, please make a Data Request to ensure that trends and patterns are interpreted correctly.

The Pacific Rocky Intertidal Monitoring Program website and associated data summaries and graphs have been developed by the Rocky Intertidal Research Group at University of California, Santa Cruz. The Principal Investigator for this group is Pete Raimondi. For any questions concerning this web-based report, please contact Melissa Miner and Rani Gaddam.
