Scientists detected 5,000 sea creatures nobody knew existed. It’s a warning.

May 26, 2023 — There are bright, gummy creatures that look like partially peeled bananas. Glassy, translucent sponges that cling to the seabed like chandeliers flipped upside down. Phantasmic octopuses named, appropriately, after Casper the Friendly Ghost.

And that’s just what’s been discovered so far in the ocean’s biggest hot spot for future deep-sea mining.

To manufacture electric vehicles, batteries and other key pieces of a low-carbon economy, we need a lot of metal. Countries and companies are increasingly looking to mine that copper, cobalt and other critical minerals from the seafloor.

A new analysis of the Clarion-Clipperton Zone, a vast mineral-rich area in the Pacific Ocean, estimates there are some 5,000 sea animals completely new to science there. The research published Thursday in the journal Current Biology is the latest sign that underwater extraction may come at a cost to a diverse array of life we are only beginning to understand.

Biden administration proposes new Pacific marine sanctuary

March 27, 2o23 — The Biden administration announced March 21 that Secretary of Commerce Gina Raimondo will consider creating a new marine sanctuary that would protect roughly 770,000 square miles in the mid-Pacific Ocean.

The new sanctuary would be created around the Pacific Remote Islands using the National Marine Sanctuaries Act, and according to a release from the administration is intended to continue Biden’s commitment to conserving 30 percent of lands and waters by 2030 – commonly referred to as the “30 by 30” plan. The full conservation area would represent the largest sanctuary of its kind in the world, and would include the existing Remote Island Marine National Monument and “currently unprotected submerged lands and waters.”

“Such protections would encompass areas unaddressed by previous administrations so all areas of U.S. jurisdiction around the islands, atolls, and reef of the Pacific Remote Islands will be protected,” a White House press release said.

Advocates for the protection said the waters are home to endangered species, and  Rep. Ed Case (D-Hawaii) also came out in support of the effort.

Transition into El Nino could lead to record heat around globe

January 30, 2023 — When the world’s largest and deepest ocean basin warms, satellites will be busy over the Pacific Ocean detecting analogous water temperatures but also, if history repeats itself, landmasses across the globe will have to deal with heat that could be record-breaking.

Since reliable technology started keeping track of world temperatures in the 1950s, the warmest year of any decade were periods dominated by an El Niño event, and the coldest were from La Niñas.

“During El Niño, unusually warm sea surface temperatures in the central/eastern tropical Pacific lead to increased evaporation and cooling of the ocean. At the same time, the increased cloudiness blocks more sunlight from entering the ocean. When water vapor condenses and forms clouds, heat is released into the atmosphere. So, during El Niño, there is less heating of the ocean and more heating of the atmosphere than normal,” National Oceanic and Atmospheric Administration experts wrote in a 2022 ENSO blog.

CLIMATE CHANGE WILL CAUSE PACIFIC’S LOW-OXYGEN ZONE TO EXPAND EVEN MORE BY 2100

November 30, 2022 — For thousands of kilometers along the western coasts of the Americas, low-oxygen waters known as oxygen minimum zones stretch out into the Pacific. In part due to climate change, this oxygen-starved region is likely to get wider and deeper, expanding by millions of cubic kilometers by the end of the century, models in a new study predict. Larger oxygen minimum zones threaten marine ecosystems and species, along with the industries that depend on them.

Oxygen minimum zones are located 200 to 2000 meters (656 to 6560 feet) beneath the surface, in the “shadow regions” of the tropical ocean, and are driven by factors such as water temperature, nutrient supply and ocean circulation patterns. Predicting how they will respond to climate change has proven difficult and the Pacific oxygen minimum zone, which is the largest in the world, is no exception. Part of the difficulty in predicting changes arises from disagreements on how to define “low” oxygen levels, which the new study explores.

Helping Hawaii: Non-profit removes 200,000 pounds of debris from Pacific

November 17, 2022 — Marine debris is an accumulating problem for Hawaiian wildlife at 57 tons per year, so one non-profit group is working to give their water and wildlife the best chance for long-term survival.

“Anything from motorcycle helmets to car bumpers to baseball bats and recently a lot of Wilson volleyballs is, believe it or not, due to a container spill that happened near Hawaii,” Kevin O’Brien told FOX Weather Monday. “And this time, we actually found a lifeboat that was part of a fire at sea from a large container ship.”

O’Brien is the president and co-founder of the Papahanaumokuakea Marine Debris Project (PMDP), a non-profit dedicated to cleaning up the Papahanaumokuakea National Marine Monument. He organized and trained a group of 16 free divers to collect dangerous debris from a 185-foot ship. Animals eat the plastic and get entangled in it.

Mission to remove tons of garbage from marine sanctuary underway

September 14, 2022 –A million-dollar mission to remove garbage from an important marine sanctuary is underway.

Kevin O’Brien, founder of Papahanaumokuakea Marine Debris Project, and his crew of 16 are preparing for their fifth mission to clean the Papahanaumokuakea Marine Sanctuary in the Northern Pacific, more than 1,000 miles away from Honolulu.

“There’s the main Hawaiian islands,” O’Brien explained pointing at a map. “Big Island, Kauai — and then we’re headed up here. This little string of tiny dots is Papahanaumokuakea.”

They depart Thursday for the month-long expedition.

According to O’Brien, they’ll likely return with garbage weighing as much as a small commercial jet airplane. He said it will fill three shipping containers and be piled in a huge mountain of garbage on the deck.

China Eyes 4 Unsecured U.S. Marine National Monuments In The Pacific

August 10, 2022 — In the deep Pacific Ocean, America’s four enormous Marine National Monuments are under siege by China. More than just ecological gems, the sprawling refuges are also underappreciated national security resources, offering quiet hiding places for America’s missile submarines, out-of-the-way testing-grounds, and training areas for various U.S. Defense Department assets.

In total, America’s deep-ocean National Monuments lay claim to almost 1.2 million square miles of pristine ocean, and China, as it pours billions of dollars into seizing much of the 1.4 million square mile South China Sea, is already looking to grab other unsecured Pacific territories, positioning to compromise the sanctity of American’s big Marine preserves. To prevent international encroachment, poaching and other sovereignty-degrading insults, America’s fragile Pacific frontiers need far more dedicated wildlife management and enforcement resources.

The current marine monument managers, the U.S. Fish and Wildlife Service, in conjunction with NOAA, are insufficiently resourced to manage over a million square miles of strategic ocean. Aside from bulking up their small law enforcement ranks, both agencies can use more funding for timely intelligence support, and procuring drones, helicopters, and some larger enforcement craft to better detect, track, document and then intercept and prosecute illegal activity in the deep Pacific.

Hawai’i Longliners Partner with Researchers to Chart Marlin Migration in the Pacific

August 10, 2022 — The following was released by the Pacific Islands Fisheries Group and the Large Pelagics Research Center:

The most comprehensive effort to date to characterize striped marlin (Kajikia audax) movements in the Central North Pacific has revealed unexpectedly broad movements among tracked specimens, with some traveling to the east coast of Australia or halfway to California from their dispersal points around Hawai‘i.

The original research, funded by a NOAA Saltonstall-Kennedy Program grant, was conducted by scientists associated with the Hawai‘i-based Pacific Islands Fisheries Group (PIFG) and the Large Pelagics Research Center (LPRC) in Massachusetts. It was recently published across two papers in the peer-reviewed journal Frontiers in Marine Science.

The papers’ findings could inform future fisheries management measures affecting striped marlin, at a time when K. audax – a top incidental catch of the longline fishery – is considered overfished in the Western and Central North Pacific.

“There is a major lack of information on the movement and ecology of striped marlin in the Central North Pacific,” said co-author and LPRC Director Molly E. Lutcavage.

“The last dedicated study of striped marlin in the Central North Pacific was almost two decades ago, and involved only a handful of marlin captured by recreational, or sport, fishers.”

Lead author Chi Hin Lam, Clayward Tam and Lutcavage partnered with commercial vessels belonging to the Hawaii Longline Association to deploy 31, $4,000 popup archival satellite tags (PSATs) on striped marlin between 2016 and 2019. Tam’s cooperative, science-based relationships with skilled longline captains made the partnerships successful.

“This is another example of the Hawaii longline vessels playing a significant role in cooperative research with leading scientists,” said Eric Kingma, Executive Director of the Hawai’i Longline Association (HLA). “We have a long history of scientific collaboration and our fleet has served as a research platform for decades. HLA congratulates the authors on their important findings and looks forward to working with PIFG and other scientists on future fisheries management and marine conservation research.”

The PSATs recorded vast horizontal movements throughout the Pacific Ocean, challenging previously-held notions that striped marlin are highly localized in their regional, coastal aggregations.

The tagged marlin, which were tracked for up to one year, routinely crossed multiple fisheries management boundaries and ocean features like seamounts and fracture zones.

One tagged marlin, PG01, made a trans-Pacific journey not previously observed for its species. Having been tagged in the Eastern Pacific Ocean, PG01 eventually made its way thousands of miles to the central east coast of Australia.

“We didn’t expect a tag showing up off Australia,” Lam said. “I would say that was 50% luck and 100% hard work. Consulting with our captains and tagging partners docked at Pier 38 in Honolulu and providing first-hand training for scientific tagging paid off.”

The tags also showed the striped marlin spent 38 and 81% of their day and night, respectively, in the top five meters of the water column.

The papers’ horizontal and vertical movement data is important for fisheries managers and stock assessment scientists, who require timely, high-quality biological and habitat data to inform population modeling and stock status.

Such data also helps identify best practices to support sustainable harvest, which could include mandated live release and time-area restrictions.

“Longline fisheries targeting tuna and swordfish benefit from any scientific information that helps to reduce unintended interaction with non-targeted catch like marlin, while pursuing economic returns on targeted catch of tuna and swordfish,” Lutcavage said.

In addition to monitoring tagged fish, researchers collected fin clips from Hawai‘i-landed striped marlin. Genetic analyses of 55 striped marlin were assigned to two genetic groups: Australia, New Zealand and Hawai‘i (19 individuals) and Hawai‘i alone (36 individuals), suggesting the Hawai‘i-based longline fleet interacted with individuals from multiple populations.

Lam, Tam and Lutcavage believe more PSAT efforts and genetics analyses are called for, to fill in the scientific gaps underscored by their latest striped marlin research. Improved technology and knowledge of the species’ biology, physiology and life history will better inform management measures for the sustainable harvest of bigeye tuna and swordfish, and a reduction of incidental catch of non-target species like the striped marlin.

Nearly 100,000 pounds of debris and ghost nets removed from reefs off Hawaii by freedivers

August 4, 2022 — A team of free divers removed nearly 100,000 pounds of debris and ghost nets from reefs and beaches off of Hawaii.

Team members with the Papahānaumokuākea Marine Debris Project (PMDP), a Hawaii-based non-profit organization, returned to Honolulu on Saturday aboard the 185-ft ship M/V Imua cleared 97,295 pounds of marine debris — including 86,000 pounds of ghost nets — from reefs and beaches of the Papahanaumokuakea Marine National Monument (Northwestern Hawaiian Islands).

Ghost nets, or large, tangled masses of discarded fishing nets, get caught on shallow coral reefs of the Hawaiian Islands, which smother and break living coral colonies. The nets also threaten endangered marine wildlife.

HAWAII: Day without ahi affects Honolulu restaurants and customers

July 25, 2022 — A Manoa Poke Shop is back in business after an Ahi shortage forced them to close for a day earlier this week. Restaurants and wholesalers tell KITV4 no Ahi ships came in on Thursday.

Off the Hook Poke Market was deliciously busy Saturday. The same cannot be said for their Thursday.

The President of the Hawaii Longline Fishing Association, which represents commercial fishermen, is quick to dispel rumors Hurricane Darby had anything to do with the drought. Ahi fishing has been having a down year, but he thinks something else may be at work.

Still the fisherman, Off the Hook, and it’s customers are all optimistic. “By nature fishermen are positive thinking when it comes to fishing. the next fish is always going to be on the next hook,” said Martin.
