As the marine biologist from Polaris Applied Sciences Inc who attached the corals at the TATOOSH anchor damage site in West Bay, Grand Cayman and the container vessel SAGA grounding at Eden Rock, Grand Cayman, I am responding to the statements made by Dr Carrie Manfrino at the official launch of the Cruise Port Referendum (CPR) campaign on Wednesday, 20 November 2019, as reported in on 21 November 2019.

Dr Manfrino is incorrect in her inferences and lacks a basic understanding of what occurred and what was completed at the vessel damaged sites. It is unfortunate that misinformation is being communicated to the public.

On 14 January 2016, the anchor chain of the 303 foot mega yacht, MV TATOOSH owned by Paul Allen destroyed approximately 14,000 square feet of protected coral reef in the area of West Bay, Cayman Islands.

The team at Polaris Applied Sciences successfully attached all the corals that remained after the anchor and chain damage on the MV TATOOSH case. If we had more available corals that had not been crushed by the anchor and chain, we would have been able to have attached them successfully as well. Dr Manfrino claims 80% of the site is dead. In their own study, CCMI identifies coral cover in Grand Cayman as 17% average. That sounds correct. After a ship grounding on a 17% coral cover site, we would have been fortunate to attain a small percentage of live coral cover. However, there was approximately 20% live cover of benthic organisms, which is a very good result. Smashed or damaged corals from a vessel hull or anchor are in greater danger of mortality than those removed carefully, yet survival was high for reattached corals in this instance, as it has been in all of our cases.  

Dr Manfrino also incorrectly claimed in another article published in the Cayman Compass on 21 November 2019 that the coral restoration work undertaken by Polaris at Eden Rock, to repair damage caused by the SAGA container ship, was unsuccessful because coral cover was lower than surrounding areas. Of course it is lower. The cargo ship crushed most of the corals in the damaged footprint. Again, all the available undamaged and partly damaged corals were attached successfully. I assume a scientist would be aware that a large vessel crashing into a coral reef would likely kill most corals and reduce the numbers available to reattach. It is disingenuous to say the vessel damage projects were unsuccessful because coral cover is lower than surrounding areas. Coral cover is lower because the large vessels crushed them, not because Polaris did not attach all remaining corals in the vessel-damaged rubble successfully.

The coral relocation project for the proposed port redevelopment is a very different project to these as this is carefully planned relocation rather than repairing significant damage. We plan to attach all corals successfully, as we always have, and expect strong survival of those corals.

This project is an environmental project in our view. Reducing anchoring on many acres of corals in Grand Cayman as a result of the building of two piers, will start a recovery process for a much larger area than that proposed to be affected in George Town harbour. The anchor damaged areas can be restored as has been done in the past. There is a net benefit of ecological gains in the longer term even if relocation is only partly successful. We fully anticipate success as we have in every other similar project. The net environmental benefit of many acres of reef no longer damaged by anchors, coral relocation and the coral nursery could be substantially greater than no-action.

I have never worked for a cruise company. I have no affiliation with the industry. This is an environmental project. I’m not saying this because Polaris want to do the job – hire someone else and I still say this is an environmental project. Greatly reducing the anchor damage that has pulverized a much larger area of reef will have benefits in perpetuity.

Polaris has just returned from Bikini Atoll where the U.S. dropped a thermonuclear weapon in WWII. Coral growth is amazing. Grand Cayman isn’t the Marshall Islands, but corals grow and recover. With some assistance, recovery can be enhanced at the anchor damaged areas to proceed faster. I am happy for Dr Manfrino to communicate with me directly to avoid misinformation in the future.  

I invite readers to come to meet us at the public meeting on Saturday, November 23 at 7pm so you may view video of the work at Eden Rock, gain a correct understanding of what we do and ask questions so you can make up your own mind.

About Greg Challenger

President

Mr. Challenger is a marine biologist with 30 years of experience in environmental resource management and marine and freshwater habitat restoration, and environmental regulation. He is currently involved in scientific support for oil spill and ship grounding response, as well as Natural Resource Damage Assessment, restoration scaling, planning, and implementation. Mr. Challenger has responded to over 70 oil spills and vessel groundings on coral reefs in the Eastern and Western Atlantic, Caribbean Sea, Pacific, and Indo-Pacific Oceans. Mr. Challenger helped form Polaris in 1998 and is currently on the board of directors.

GEC-Burnaby

Following completion of his undergraduate degree in 1985, Greg taught marine resource management and coral ecology at the Center for Marine Resource Conservation in the Turks and Caicos, BWI, the Newfound Harbor Marine Institute (NHMI) in the Florida Keys, and aboard the SSV Westward in the Eastern Caribbean. He developed and taught field education programs in coral reef, mangrove and seagrass ecology. Greg also taught advanced and scientific diving courses at NHMI. During breaks in the education programs in the Florida Keys, Greg worked as a Foreign Fisheries Observer in the Aleutian Islands, Alaska living aboard Japanese, Russian and Korean fishing trawlers in the Bering Sea and Gulf of Alaska collecting catch data for fishery management purposes. Greg returned to Alaska following completion of graduate school in 1990 to study the potential adverse effects of fishery practices on marine mammals and birds in Prince William Sound and Unimak Island, Alaska. He collected data aboard fishing vessels and conducted aerial surveys of animal populations along the Copper River Delta and Prince William Sound.

In 1991, Greg joined Beak Consultants, Inc. (Beak) in Portland, Oregon. Greg worked on studies throughout the Pacific Northwest and Alaska including dioxin studies in the Columbia River, ecological studies related to hydropower re-licensing, threatened and endangered wildlife studies, and wetland and aquatic habitat design and construction. Greg became a Certified Professional Wetland Scientist and participated in over 40 wetland and aquatic habitat restoration and creation projects in Alaska, Washington, Oregon, Idaho, and California. Greg was named a Senior Scientist and the head of the Wetland Science Group in the Portland office of Beak in 1994.

During several sabbaticals from consulting, Greg taught oceanography as part of a Boston University accredited program run by Sea Education Association in Woods Hole, Massachusetts. He sailed aboard the SS/V WESTWARD from Maine to the Lesser Antilles and the Virgin Islands. Greg directed student research projects involving mapping of submerged active volcanoes off the coast of Grenada, assessing tar and plastic levels in the Western Atlantic, and modeling geostrophic flow and the island mass effect in the St. Lucia Channel. Greg also worked as faculty for the School for Field Studies Center for Marine Resource Conservation and Management in South Caicos, Turks and Caicos Islands (TCI), British West Indies. He taught Marine Resource Management and directed research projects relative to local conch and lobster fishery practices, aquaculture, harbor dredging, and solid waste disposal. Since 1993, he has returned to South Caicos several times to lecture and recently performed an assessment of coral reef injury resulting from the large-vessel grounding in West Caicos, TCI for the Department of Environment and Coastal Resources.

In 1997, Greg moved to Seattle, Washington to work exclusively with the Marine Division of Beak Consultants. Greg provided scientific support and environmental injury assessment for numerous oil and chemical spill projects. Greg also performed coral reef injury assessments and helped to develop restoration plans following damages from ship groundings for numerous projects in the Caribbean Sea and Central America, as well as developed numerous successful habitat mitigation, restoration and creation plans for aquatic environments.

Greg left Beak in 1998 to help form Polaris Applied Sciences, Inc. Greg is currently the President of Polaris and provides scientific support and project management for oil spill and ship grounding emergency response and Natural Resource Damage Assessment under the Oil Pollution Act.
