Entering the Hawaii Undersea Research Laboratory hangar is akin to stepping onto the set of a Spielberg film.
The dull metal shell, perched on the Makai pier along the Windward Coast of Oahu, is nondescript, but the inside bristles with Zodiac boats and a dizzying assortment of hoists and tools, and the walls are festooned with 30 years of snapshots.
At the center of it all, two 20-foot-long Pisces submarines sit atop skids like alien spacecraft, their robotic arms outstretched, beckoning for another mission.
The laboratory, part of the University of Hawaii and better known as HURL, has been the sole submersible-based United States deep-sea research outpost in the mid-Pacific since the 1980s.
At its helm is Terry Kerby, perhaps the most experienced submersible pilot alive.
With a crew of five, Mr. Kerby and the Pisces subs have discovered more than 140 wrecks and artifacts, recovered tens of millions of dollars in lost scientific equipment, and surveyed atolls and seamounts whose hydrothermal vents and volcanoes were unknown.
The Pisces IV and Pisces V research submarines could soon be mothballed.

“It’s
very unusual to have a facility that large and well-equipped in the
middle of a large ocean basin,” said Robert Dunbar, a Stanford
oceanographer.
“They’ve done a remarkable thing over there, largely due to Terry’s expertise.”

The forces at play are the same as in many other realms of science — dwindling budgets, of course.

Robotic
subs can stay down for days and reach extraordinary depths, instantly
relaying their finds to scientists and an Internet-connected global
audience.
But they cannot go everywhere, and many scientists argue that studying the deep without direct human observation yields at best an incomplete understanding.

“You can’t replace a Terry Kerby with a robot,” said Andy Bowen, principal engineer at Woods Hole. “It’s not possible.”
At
65, Mr. Kerby is tanned and fit, thanks to daily two-mile ocean swims.
He has been piloting submersibles at Makai for better than three decades, starting in the mid-1970s harvesting corals.
He shifted to the University of Hawaii and the National Oceanic and Atmospheric Administration, which had bought the Makai facility to expand the nation’s deep-sea capabilities.

In
1985, Mr. Kerby found the Pisces V submersible idled in Edinburgh and
persuaded the university to spend $500,000 for it.
Relatively big, it could dive to 6,500 feet.
“She cost $4 million to build in 1972,” he said. “And would cost $50 million to build today.”

Pisces
V came with no instruction manual, but Mr. Kerby found it was highly
maneuverable and could hover motionless, even in strong currents.
It also operated untethered from a mother ship, allowing exploration of caves and overhangs. Coupling Pisces with the University of Hawaii’s research ship, the Ka`imikai-O-Kanaloa, and a home-built submersible platform enabled Mr. Kerby to carry out missions from 60 feet down, during surface conditions too rough for any other submersible.
Mr. Kerby racked up discoveries, beginning with exploration of the Loihi seamount off Kona. Eighteen years of return missions have revealed that an area once thought dead is a vibrant world of myriad ecosystems and volcanism still shaping the Hawaiian Islands.
Along Loihi and other slopes, the team discovered living corals that predate even California’s bristlecone pines.

In part 1 of a two-episode look at the submersible operation at the Hawaii Undersea Research Lab, we meet Terry Kerby, a legend of the underwater world.
Terry has been piloting submarines for over 30 years.
He and his team recently redeployed an old technology to help them save money in times of reduced funding for scientific research. The LRT-30a is a barge that transports the sub out to its dive site.
A team of divers then takes the barge underwater with the submarine still attached and proceeds to launch the sub while it is underwater.

In
2000, Mr. Kerby acquired a sister sub, the Pisces IV, from Canada for
$80,000.
Exploring in tandem made diving safer and enabled film crews to show discoveries in the context of the submersibles.
The subs have appeared in more than 20 documentaries, including National Geographic’s “Fires of Creation,” in which the oceanographer Robert Ballard, whose discoveries included the wreckage of the Titanic, descended with Mr. Kerby to the caldera of Loihi.

Besides plumbing geological and ecological mysteries, the Pisces subs have made dives that sharpened views of history.
A little more than an hour before the first bombs fell in Pearl Harbor on Dec. 7, 1941, the American destroyer U.S.S. Ward
reported that it had sunk a tiny submarine near the harbor entrance.
But in a blunder that still fuels conspiracy theories, the report never reached far enough up Navy command to initiate a mobilization of defenses.
The Ward’s claim was disputed, even in the official Pearl Harbor investigation report.
The sub thus became a holy grail for marine archaeologists and historians.

Pisces V lauched from R/V KoK
In
August 2002, Mr. Kerby lay across the bench of the Pisces V, 1,200 feet
down, gazing at the dark, frigid world beyond his porthole.
For hours he had been sweeping the seafloor four miles south of Pearl Harbor, hunting for the mythic sub amid three dozen potential sonar targets and fighting a rising sense of futility.
“We were chasing our tails down there,” he said.

“We were chasing our tails down there,” he said.
But then, looming out of the darkness, Mr. Kerby faced a torpedo shape three times as long as the Pisces. It was a 78-foot-long submarine
bearing the exact damage – a four-inch hole punched just beneath its
conning tower — described by the Ward’s crew.
“We’d searched for 10 years,” Mr. Kerby said.
“I just couldn’t believe it.”

After
that find, NOAA directed Mr. Kerby to further document the wreck-strewn
waters off south Oahu.
In another National Geographic project, the team discovered four mammoth Japanese I-series submarines captured by the Navy at the end of World War II and scuttled to keep them out of Soviet hands.

Experience the first view of a World War II-era Imperial Japanese Navy mega-submarine, the I-400, lost since 1946 when it was intentionally scuttled by U.S. forces after its capture.
It now sits in more than 2,300 feet of water off the southwest coast of O'ahu.
“What
the Pisces program has done, mostly underfunded and unappreciated, over
the years is unmatched,” said Sylvia Earle, former chief science
officer for NOAA.
“It’s baffling to me that more understanding and funding hasn’t been heaped upon them.”

Five
years ago, piloted deep-sea exploration appeared on the verge of a
boom, funded by wealthy explorer/entrepreneurs.
In 2012, after spending $10 million building his Challenger Deep submersible, the filmmaker James Cameron became one of three humans to reach the 6.8-mile depths of the Marianas Trench, the deepest ocean spot on Earth — and the only one to do it solo.
The Virgin Airlines founder Richard Branson promised a new era of exploration with his $17 million Virgin Oceanic submarine.
And Eric E. Schmidt, Google’s chairman, joined with Dr. Earle on the $40 million Deep Ocean project.

Yet
all those programs have withered.
And by fiscal year 2014, the deep-sea budget for NOAA was down to $26 million.
For comparison, NASA’s exploration budget was $4 billion.
The United States Navy has abandoned piloted submersibles with the exception of Alvin, which it owns jointly with Woods Hole.
In 2013, NOAA said it would no longer fund the Pisces program, leaving the United States with no Pacific deep-sea facility.
HURL has money to last until the beginning of 2016.
After that, the university may be forced to sell the submersibles.
“There are only eight deep-diving submarines left operating in the world” that can go 6,500 feet or deeper, said John Wiltshire, director of HURL and a member of the Woods Hole submersible scientific advisory committee.
“So we’re about to lose a quarter of the world’s fleet.”

What
changed?
To hear Dr. Ballard tell it, the shift began during a 1977 dive aboard Alvin off the Galápagos Islands.
About 8,000 feet down, Dr. Ballard noticed a colleague paying more attention to the camera monitor than to Alvin’s tiny windows.
“He turned his back on me to look at the screen,” Dr. Ballard said.
“I said, ‘Why?’ He said, ‘I can get closer.’ I said, ‘Then why the hell are you here?’ ”

“I said, ‘Why?’ He said, ‘I can get closer.’ I said, ‘Then why the hell are you here?’ ”
Afterward,
Dr. Ballard said he realized fundamental truths of piloted deep-sea
exploration: It’s cold and scary, time in the deep is limited, and
robotic vehicles might do the same work for less money.
He persuaded the Navy to fund two remote exploration vehicles, Argo and Jason, for use by Woods Hole.
On Sept. 1, 1985, Argo first filmed the wreckage of the Titanic.
Since then, remote deep-sea vehicles have proliferated in exploration, mining and drilling. Dr. Wiltshire estimates perhaps 10,000 are in operation.

NOAA’s deep-sea efforts
are focused on two ships: its own Okeanos Explorer, based in Rhode
Island, and the E/V Nautilus, a joint project with the Ocean Exploration
Trust, founded by Dr. Ballard and based in Connecticut.
Nautilus has an autonomous underwater vehicle that follows a programmed route and two tethered remote submersibles.

Typically,
Dr. Ballard’s ships carry just one or two senior oceanographers;
engineers and technical staff deploy and monitor the submersibles,
which, via satellite link, deliver real-time images across the world via
the Internet.
Terry Kerby and his Pisces subs have discovered more than 140 undersea wrecks and artifacts.

Dr.
Ballard described a recent Nautilus expedition that sent its
submersibles two and a half miles down into the Cayman Trough.
In a piloted dive, the descent and ascent would take six hours each, leaving mere minutes for seafloor exploration.
“Now we’re going down to 20,000 feet and spending days,” he said.
“And we have the entire world participating.”

To
most marine scientists, including Mr. Kerby, robots have clearly won
the deep-sea war.
It’s now a question of whether lingering advantages to piloted exploration should be discarded.

Mr. Kerby described a recent robotic mission that Pisces might have done better.
In
2012, Ric Gillespie, a retired naval aviator, and Dr. Ballard announced
a sonar hit off Nikumaroro Island in the South Pacific that might
represent the wreckage of the Lockheed Electra flown by Amelia Earhart.
Mr. Gillespie requested Mr. Kerby for the expedition, but the Pisces subs were down for maintenance, so his team instead relied on robotic technology.
The tethered sub was unable to explore the near-vertical sea walls and could not deploy over days of rough seas.
Eventually, an untethered robotic vehicle became lodged in a reef overhang and had to be rescued by a tethered robot.
The recovery nearly required the University of Hawaii’s Ka`imikai-O-Kanaloa to deploy perilously close to a reef.

a horrible way to search,” Mr. Gillespie said.

At
the university, Dr. Wiltshire cited plans for bringing Alvin and the
Nautilus rovers to explore newly created Pacific marine monuments.
Rates for Nautilus are in the range of $35,000 to $40,000 a day, while Alvin and its support vessel Atlantis II cost $60,000 to $70,000 a day.
HURL can deploy both Pisces subs for $48,000 a day, “and that’s not counting the transit time and expense to get there,” Dr. Wiltshire said.
“It takes us 15 days, but it takes two months to bring those ships over from the East Coast.”

“It takes us 15 days, but it takes two months to bring those ships over from the East Coast.”
Dr.
Ballard countered that comparison must take into account the time his
rovers can stay submerged — days at a time, as opposed to eight hours or
so for Pisces or Alvin.
Dr. Bowen, who oversees the robotic and piloted programs for Woods Hole, says piloted exploration still has plenty of benefit.
Operating two of only eight deep-diving submersibles in the world, the Hawaii Undersea Research Laboratory (HURL) at the University of Hawaii - Manoa provides science and engineering communities with safe and efficient, cutting edge submergence capability.
A regional center in the NOAA Office of Ocean Exploration and Research, HURL supports proposals to conduct undersea research in offshore and nearshore waters of the main and Northwestern Hawaiian Islands and waters of the central, southwestern, and western Pacific, including the new marine national monuments.
“There’s
no question that the strong suit for robotics is that you can engage a
larger number of people in the process of exploration and discovery,”
Dr. Bowen said.
But taking in all the undersea factors — currents, sounds, land forms, interactions between animals and their environment — humans are still far better at synthesizing what’s going on in the deep sea, he said.
“We hear that all the time from researchers who have looked at the video monitors and data screens from Jason, but then also gone down in Alvin.
It’s stunning how different their perception of the environment is.”

According
to Craig McLean, the assistant administrator for oceanic and
atmospheric research at NOAA, decisions about HURL’s future were mainly a
matter of budget constraints and emerging technology.
HURL was funded as part of NOAA’s National Undersea Research Program.
Scientists competed for NOAA-backed studies, and the agency maintained and provided the equipment — like Pisces submarines — to the winners.
That program was phased out in favor of an unpiloted, Internet-connected virtual model that includes on-call scientists around the world.

“We
realized we can’t afford to do it all,” he said.
“So we had to ask, what are we doing and how can we have it be inclusive? So scientists who can’t dive — they have a presence through telepresence.”
“So we had to ask, what are we doing and how can we have it be inclusive? So scientists who can’t dive — they have a presence through telepresence.”
In
addition to making headlines with discoveries of bizarre creatures,
surveys with the Okeanos have, he said, had more practical applications.
A fisheries survey, for example, resulted in the recent protection of 38,000 nautical square miles of ocean off the East Coast.

Mr.
McLean said that should a scientist bring a proposal before NOAA or the
National Science Foundation that Pisces was well suited for, Mr.
Kerby’s team could still get funding on a mission-by-mission basis.
He
further agreed with a sentiment expressed by Dr. Earle, that in a time
of dramatic changes in the climate and ocean itself — some 90 percent of
which remains completely unexplored — he would prefer that NOAA had a
wider arsenal of discovery at its disposal.
“We’re doing as much as we can,” he said.
“But we have to get into these difficult situations where we have to make our priorities.”
“We’re doing as much as we can,” he said.
“But we have to get into these difficult situations where we have to make our priorities.”
In
the meantime, Mr. Kerby and his maintenance chief, Steve Price, have
been hustling.
Mr. Price has been funded to compile a database of all Pisces discoveries for use by NOAA.
A World War II documentary project has kept Mr. Kerby busy lately, and a series of geology, undersea cable and sewer outfall surveys will keep HURL funded through year’s end.
He says he is confident more work will materialize, preventing his crew from having to follow the route of many former colleagues into oil and gas exploration.
He’d love to secure the resources not only to keep his subs running, but to add a full-time robot sub to HURL’s fleet.

“An
associate of mine at Woods Hole upper management said, ‘HURL doesn’t
stand a chance,’ ” Mr. Kerby said.
“ ‘They’re too far from the flagpole.’Well, we are. We’re way out here on the ocean frontier, in the prime spots, and we’re one of the most cost-effective operations around. With all the new and unexplored monuments in the western Pacific, and all the groups that need to do that exploration, we’re the only viable tool with experience in these environments.”

He paused.
