NOAA: Scientists Monitor Coral Reef Ecosystems Throughout the Hawaiian Archipelago

April 22, 2019 — The following was published by NOAA Fisheries:

Our scientists and managers depend on research surveys to monitor the status and trends of the coral reef ecosystems across the Hawaiian Archipelago over time. Coral reefs around the globe, including Hawaiʻi, are threatened by climate change, disease, land-based sources of pollution, and unsustainable fishing practices.

During expeditions this spring and summer, teams of scientific divers from NOAA’s Pacific Reef Assessment and Monitoring Program will assess reef fish and corals in the context of changing environmental conditions. They will collect images of the ocean floor to create 3D models of the reefs. The abundance and distribution of reef fish and coral reef organisms are used to characterize the conditions and integrity of our coral reef ecosystems. Over time, we can see how they have changed—an important part of managing and conserving reef-associated life in the region.

This expedition marks the 20th anniversary of the Pacific Reef Assessment and Monitoring Program’s inception in 2000, and will be conducted using the NOAA Ships Oscar Elton Sette and Rainier. We will add our research this season to collections from baseline monitoring surveys across the Pacific and in Hawaiʻi in 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2008, 2010, 2013, and 2016.

Study Locations

The Sette will survey the main Hawaiian Islands: Kauaʻi, Niʻihau, Maui, Lānaʻi, Molokaʻi, Kahoʻolawe, Oʻahu, and the island of Hawaiʻi. The Rainier will survey portions of the Papahānaumokuākea Marine National Monument in the remote Northwestern Hawaiian Islands: French Frigate Shoals, Lisianski/Neva Shoals, Pearl, and Hermes Atoll, and Kure Atoll. At each site, the ships will deploy small boats to reach study areas, including locations along the leeward and windward exposures, near the channels between islands, and in forereefs, backreefs, and lagoons.

Of particular note, our researchers are fortunate to return to the protected island of Kahoʻolawe, where few people have access. Kahoʻolawe was once a bombing range for the U.S. Navy, and it is now an island reserve under the state of Hawaiʻi.

Following our initial visit in 2016, this expedition is the second time that our program will survey the reef systems of Kahoʻolawe. Those surveys found that the reefs in certain areas were in good condition, and roving predators such as jacks were abundant when compared with other sites around the main Hawaiian Islands.

Research Methods

As the threats to coral reefs and marine ecosystems grow, our researchers lean more heavily on digital imaging to increase our monitoring capabilities.

We create a mosaic (2D) and 3D model of an area using structure from motion, a photogrammetry technique (mapping using the distance between objects). It estimates 3D structures by aligning 100s to 1000s of overlapping images.

Combining seafloor images to create 3D models of large areas of reef tract is a process called “structure-from-motion” photogrammetry, which is a new effort for our program. During this mission, we will conduct structure-from-motion surveys across the archipelago to measure the density, surface area, partial mortality, and health of corals. Our team will conduct structure-from-motion surveys at fixed stations to assess the growth, mortality, and recruitment of individual coral colonies, which will provide valuable information on the resilience of coral reefs to local and global threats.

Scientists aboard the Sette and Rainier will measure water temperature, salinity, carbonate chemistry, and other physical characteristics of the coral reef environment with an assortment of oceanographic monitoring instruments. Researchers will assess the potential early effects of ocean acidification on coral reef growth with calcification accretion units and bioerosion monitoring units.

Longline fishing industry scrutinized for hiring of foreign fishermen

November 2, 2017 — HONOLULU — The Hawaii Longline Association has jumped into a legal fight they say threatens their livelihood. Longliners oppose a Maui fisherman’s complaint against the state.

In a Circuit Court filing, the association defends its practice of hiring fishermen from foreign countries and challenges a lawsuit filed by fisherman Malama Chun.

He demands the state stop issuing commercial fishing licenses to foreign fishermen.

“The folks that make up the majority of the longline fishing boats are not lawfully admitted to the United States. When they get here, they’re subject to deportation orders that the boat captains hold,” said Chun’s attorney Lance Collins.

But Longline Association president Sean Martin said there’s nothing illegal about the state’s licensing practices.

Hawaiian fisherman sues to restrict foreign fishing licenses

August 3, 2017 — HONOLULU — A Native Hawaiian fisherman is asking an environmental court to stop Hawaii officials from issuing commercial fishing licenses to those who aren’t legally admitted into the United States.

Malama Chun, a Maui resident who fishes as a cultural practice, filed an appeal on July 27 of a state Board of Land and Natural Resources decision denying his petition. Chun filed his petition in April in response to an Associated Press investigation that found hundreds of foreign fishermen confined to boats and some living in subpar conditions. Hawaii grants the foreign fishermen licenses to fish, but they aren’t allowed to enter the country.

The board, which regulates fishing licenses, denied the petition last month without a hearing. Chun didn’t show how not issuing the licenses would address his concerns about overfishing and cultural practices. His attorney, Lance Collins, said Tuesday that because the board made a decision without holding a hearing or conducting any fact-finding, the board must take all stated facts as true.

Researchers find abundant life in Hawaii’s twilight zone

October 5, 2016 — HONOLULU — Coral reefs in Hawaii’s oceanic twilight zone, where light still penetrates and photosynthesis occurs, are abundant and host a wide variety of life, a new study shows.

A paper published Tuesday in the journal PeerJ revealed that some of these ecosystems off the Hawaiian archipelago, particularly an area off Maui, are the most extensive deep-water reefs ever recorded.

The ecosystems, found in waters from 100 to 500 feet deep, host more than twice the amount of unique Hawaiian fish species as their shallow-water counterparts, and they are much more extensive than previously known.

“What is unique about this study is how vast and dense the coral cover is,” Richard Pyle, a Bishop Museum researcher and lead author of the publication, told The Associated Press.

Please join the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Fish and Wildlife Service (FWS) for a public meeting to discuss the proposed expansion of the Papahānaumokuākea Marine National Monument.

On June 16, 2016, U.S. Senator Brian Schatz submitted a proposal to President Obama, requesting consideration of expanding the current boundaries of the Papahānaumokuākea Marine National Monument – drawing attention again to the rich cultural and scientific resources of the Northwestern Hawaiian Islands (NWHI).

As the Administration evaluates the proposal, we are seeking input from all interested parties to ensure that any expansion of the Monument protects the unique features of the NWHI for future generations while recognizing the importance of sustainable ocean-based economies.
