Multi-Agency Rocky Intertidal Network  

Our coastlines are home to dynamic, highly diverse biological communities that are subject to dramatic changes due to natural phenomena and human activity. MARINe is committed to the long-term study of these rocky intertidal communities across the coast. We invite you to learn about them so that together we can understand how best to protect these valuable resources.
Pacific Rocky Intertidal Trends and Analyses


Many of the coastal sites have been monitored by Multi-Agency Rocky Intertidal Network for periods of 15 to over 25 years. MARINe represents the largest program of its kind.

  • Abalone Decline

Sea star wasting syndrome (SSWS) is a general description of a set of symptoms that are found in sea stars. Typically, lesions appear in the ectoderm followed by decay of tissue surrounding the lesions, which leads to eventual fragmentation of the body and death. A deflated appearance can precede other morphological signs of the disease.

  Seastar Disease

Habitat suitable for black abalone is systematically surveyed to estimate the current number of individuals and determine aerial extent of the disease. These studies are critical in promoting the recovery of the species.

Detailed Poster


MARINe was honored with the USDOI's Partnership in Conservation award in recognition of the unique and extensive partnership that was developed among federal, state and tribal governments, local agencies, universities and private groups dedicated to the study and management of rocky intertidal shoreline habitats, one of our most diverse and vulnerable coastal resources.

The Channel Island National Park first identified the sharp decline in the mid-1980's on the islands; BOEM/UCSB first discovered mainland evidence of the decline at Pt Conception in 1992. MARINe has continued to follow the decline of the population.
