Pacific bird refuge struggles as ocean garbage patch grows

November 11, 2019 — Flying into the uninhabited Northwestern Hawaiian Islands, Midway Atoll appears out of the vast blue Pacific as a tiny oasis of coral-fringed land with pristine white sand beaches that are teeming with life.

But on the ground, there’s a different scene: plastic, pollution and death.

With virtually no predators, Midway is a haven for many species of seabirds and is home to the largest colony of albatross in the world.

But Midway is also at the center of the Great Pacific Garbage Patch, a vast area of floating plastic collected by circulating oceanic currents. The Hawaiian Islands act like a comb that gathers debris as it floats across the Pacific. A recent analysis found that the patch is accumulating debris at a faster rate than scientists previously thought.

Midway is littered with bird skeletons that have brightly colored plastic protruding from their decomposing bellies. Bottle caps, toothbrushes and cigarette lighters sit in the centers of their feathery carcasses.

Researching and Rescuing Hawaiian Monk Seals and Green Sea Turtles

September 24, 2019 — The following was released by NOAA Fisheries:

NOAA field biologists returned to Honolulu after 3 months at remote camps in the Northwestern Hawaiian Islands. They researched and rescued some of the most iconic and endangered species in Hawaiʻi—Hawaiian monk seals and green sea turtles.

This year, our field biologists established protected species camps at five atolls:

  • French Frigate Shoals.

  • Laysan Island.

  • Lisianski Island.

  • Pearl and Hermes Reef.

  • Kure Atoll.

Our field teams also conducted population assessment surveys at Nihoa, Mokumanamana (Necker), and Midway Atoll.

NOAA has operated monk seal research camps at all major breeding sites for 36 years. We have maintained French Frigate Shoals turtle nesting records, which stretch back 47 years. Several of the field researchers have been around for decades. They have some of the most consistent sets of eyes and ears in the Papahānaumokuākea Marine National Monument. They are able to observe changes in the ecosystem, improving our response to threats to these important species.

NOAA: ‘The Reefs Weren’t Damaged, They Were Just Gone’

August 19, 2019 — In October, Hurricane Walaka literally wiped East Island off the map, and with it the primary nesting grounds of thousands of threatened green sea turtles in French Frigate Shoals.

But until now it wasn’t clear what happened to the surrounding reefs and sea life in this remote stretch of the Northwestern Hawaiian Islands, about 550 miles from Honolulu.

Researchers with the National Oceanic and Atmospheric Administration and their partner scientists returned this week from a 22-day expedition in Papahanaumokuakea Marine National Monument.

Divers discovered devastating damage to the coral at French Frigate Shoals, an atoll featuring a crescent-shaped reef. Photos show rubble not recognizable as the former coral reef, one of the most significant reef systems in the nearly 600,000-square-mile monument, NOAA officials revealed Thursday.

Loss Of NOAA’s Primary Honolulu Ship A Setback For Research

June 18, 2019 — Honolulu’s flagship National Oceanic and Atmospheric Administration research vessel — the Hiʻialakai — has spent the last several months rusting in an Oregon boat dock, and there are no plans to return it to service.

While in Hawaii, the Hi’ialakai harnessed its specialized scuba diving capabilities to perform a variety of missions, including monitoring deep-sea wildlife and cleaning up fishing debris from the shores of the Papahanaumokuakea Marine National Monument.

NOAA discovered structural issues — including extensive corrosion, pipe failures and propulsion problems — during an inspection late last year, according to David Hall, public affairs specialist at NOAA’s Office of Marine and Aviation Operations.

HAWAII: Talk on marine debris is Friday

June 7, 2019 — Kilauea Point Natural History Association, which provides support to the Kauai National Wildlife Refuge Complex, has teamed up with Kristen Kelly of the state Department of Land and Natural Resources Division of Aquatic Resources, Marine Wildlife Program, to present a talk on ocean debris in celebration of World Oceans Day 2019.

The talk will focus on marine debris in the uninhabited Northwestern Hawaiian Islands and its impacts on wildlife in the Papahanaumokuakea Marine National Monument at a free event Friday from 7 to 8 p.m. at the Princeville Community Association clubhouse.

“The problem of plastic pollution in the environment is a global one. In Hawaii, we feel the impacts all along our beaches and shorelines,” said a press release.

“From ghost nets and ropes that entangle wildlife, to plastic bits that find their way into the bodies of our ocean-dependent animals, to the littered beaches where we all love to spend time, it is becoming impossible to ignore this environmental crisis.”

NOAA teams departing for expedition to Papahanaumokuakea Marine National Monument

May 15, 2019 — It’s time again for a team of researchers to head out to the Northwestern Hawaiian Islands at Papahanaumokuakea Marine National Monument, where they will set up camps for the next five months.

The National Oceanic and Atmospheric Administration’s Ship Oscar Elton Sette departs on Wednesday for Papahanaumokuakea, one of the largest, protected marine conservation areas in the world and home to endangered Hawaiian monk seals, threatened green turtles and millions of seabirds.

NOAA researchers this year will conduct the usual tasks — measuring and tagging all weaned Hawaiian monk seal pups, conducting beach counts and removing marine debris. A team of biologists will also measure and tag basking and nesting sea turtles and monitor nesting activities at French Frigate Shoals.

Another field team, however, will focus on researching how animals responded to the loss of East Island at French Frigate Shoals, where a majority of Hawaii’s green sea turtles nest, and dozens of Hawaiian monk seals pup. East Island was washed away by Hurricane Walaka in October 2018.

Field researchers from NOAA, along with six partner organizations, will focus their research and conservation activities at French Frigate Shoals as well as Laysan Island, Lisianski Island, Pearl and Hermes Reef and Kure Atoll. They will also take day trips to survey Niihau, Nihoa, and Mokumanamana islands and Midway Atoll.

The NOAA Ship Oscar Elton Sette will transport state Department of Land and Natural Resources staff and supplies to Kure Atoll. At Lisianski Island, the U.S. Fish and Wildlife Service will help the NOAA team find routes through the dense vegetation that blocks the shoreline and access to monk seals.

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.

Divers haul in large amount of debris from marine monument

November 13, 2018 — A team of divers hauled in nearly 165,000 pounds (75,000 kilograms) of abandoned fishing nets and plastic waste during a cleanup expedition at Papahanaumokuakea Marine National Monument, federal officials said.

The 18 divers left Sept. 19 and returned Oct. 29 from a trek to the chain of isles and atolls located 1,200 miles (1,931 kilometers) northwest of the main Hawaiian islands, according to the National Oceanic and Atmospheric Administration, which runs the expeditions.

The divers hauled in about 82 tons (74 metric tons), which is comparable to the weight of 45 mid-sized cars or one space shuttle, NOAA said.

The team of divers from NOAA Fisheries and University of Hawaii’s Joint Institute of Marine and Atmospheric Research sorted out the debris Friday.

The group split the debris into categories such as plastic laundry baskets, fishing nets, tires, buoys and smaller personal-care items such as plastic toothbrushes and combs.

Papahanaumokuakea Marine National Monument is uninhabited by humans. But due to its central location in the system of circulating currents called the North Pacific Gyre, the debris has been carried by currents to its shores for decades.

NOAA’s marine debris team has been going on expeditions to the Northwestern Hawaiian Islands almost yearly to survey and remove litter since 1996. Cumulatively, including the last mission, teams have collected about 2 million pounds (0.91 million kilograms) of debris.

The litter does ecological damage at Papahanaumokuakea, said NOAA’s Kevin O’Brien, who served as chief scientist for the mission this year.

Protecting Paradise: Marine Debris Team Does the Heavy Lifting

The team removed more than 160,000 pounds of lost or abandoned fishing nets and plastics from the remote Northwestern Hawaiian Islands, an ecologically and culturally significant area, part of the Papahānaumokuāea Marine National Monument.

November 12, 2018 — Stretching 1,200 miles northwest of the main Hawaiian Islands, a chain of remote islands and atolls known as the Northwestern Hawaiian Islands are hundreds of miles from the nearest human populations. Yet, these beautiful coral reefs and uninhabited shorelines are centrally located in the North Pacific Gyre, where currents gather marine debris from all around the Pacific Ocean.

NOAA’s marine debris team travels from island to island by ship and small boat, carefully pulling derelict “ghost” fishing gear off of underwater reefs and collecting plastic debris from shorelines. They clean up nets and other debris that damage coral reefs and threaten wildlife, including endangered Hawaiian monk seals and green sea turtles. Hauling debris is often a dirty, exhausting, and sometimes fly-filled task, but the team loves its work.

HAWAII: NOAA ship evacuates biologists from Papahanaumokuakea ahead of Hurricane Walaka

October 5, 2018 — The National Oceanic and Atmospheric Administration’s research ship Hi‘ialakai has taken seven NOAA field biologists away from French Frigate Shoals ahead of Hurricane Walaka, which is approaching Papahanaumokuakea Marine National Monument today.

The field crew of three green sea turtle biologists and four monk seal biologists was not scheduled to leave French Frigate Shoals until mid-October, said Megan Nagel, spokeswoman for the U.S. Fish and Wildlife Service — Pacific Region.

Instead, Nagel said in an email, they were “recovered ahead of their scheduled mid-October departure date by the NOAA ship Hi‘ialakai.”

On Monday, a U.S. Coast Guard crew flew a HC-130 Hercules from Air Station Barbers Point to Johnston Atoll and evacuated four U.S. Fish and Wildlife Service biology field workers from the wildlife refuge.

Hurricane Walaka was a Category 4 storm with sustained winds of 130 mph when it passed the tiny four-island atoll Tuesday.
