Galápagos Blu-ray delivers great video and poor audio in this overall recommended Blu-ray release
The inspiration for Darwin's theory of evolution, the Galápagos Islands are a living
laboratory, a
geological conveyor belt that has given birth to and seen the death of many species
of plants
and animals. As the western islands rise up from the sea offering a chance of life,
the eastern
islands sink back beneath the waves guaranteeing only death. Between the two are
the middle
islands; fertile, lush land in its prime that contains an incredible diversity of life.
Nowhere else
on the Earth are the twin processes of creation and extinction of species so starkly
apparent...
see it all unfold before your eyes in this stunning series filmed entirely in high
definition from
the BBC and the National Geographic Channel.
There is little wonder why a humble group of Pacific islands - el archipielago de Colón –
continue to capture the attention and fascination of so many, throughout the centuries of
contemporary human history. The Galápagos islands, born of fire, shaped by the sea, and inhabited
by the fortunate and the hapless, are truly a biological microcosm and a geologic
phenomenon.
It is not known if there were ever any human visitors to these lonesome isles until the 16th
century, when Tomás de Berlanga, the bishop of Panama, accidentally sailed into them in March of
1535 when journeying to Peru. He later wrote of a cursed and infernal place – to his eyes, a hell on
Earth. The harsh and highly variant climates of the islands certainly seem forsaken upon first
impression. But as this thorough BBC documentary attests, the unique nature of these glorified
rocky outcroppings is revealed upon further exploration.
A young Charles Darwin explores the peculiar island residents, including this giant tortoise.
Through impressive camerawork and Tilda Swinton's engrossing narration, the history and
characteristics of many of the major islands – from Isabela, the largest, and with a shape not
unlike an anchored seahorse, to the eastward islets of Genovesa and Espańola – are depicted at
length. Each is its own identity, with its own ecosystem of specialized flora and fauna; life forms
that have had to adapt to the available resources. The islands themselves are highly individual
due to the whims of the ocean and the boiling earth beneath it. Multiple Pacific currents have
different effects on Galápagos, including the Cromwell from the west, which dredges up nutritious
deep sea microorganisms that go on to feed a slew of marine species. The Panama current from
the northeast leads to less marine abundance, but brings warmer weather and increased rainfall.
The currents are dominant at different periods of the year, and wildlife on the islands is very
dependant on this ebb-and-flow cycle.
In addition, the Galápagos are positioned over a geologic "hot spot," where volcanic activity
occurs in the middle of a tectonic plate. As underwater volcanoes erupt, and magma
accumulates enough to form dry land, the eventual island of fresh igneous rock travels roughly
southeast, in a "conveyer belt" fashion as the ever-active tectonic plate upon which it rests shifts
in that direction. At first, these volcanic deposits are completely barren, and prohibit the
presence of most life. Hardy pioneers, like cacti, eventually take hold and begin to form some
semblance of organic matter on the surface. Over time, other plants follow, as well as a handful
of creatures that have adapted to the conditions of each island as they slip slowly southeast,
becoming more fertile as they go.
It is this specialization, particularly among animal life, that so intrigued the young naturalist
Charles Darwin, who visited the island in September of 1835 – a full 300 years after Tomás de
Berlanga. Spending five weeks sailing and mapping the islands with the crew of the HMS Beagle,
Darwin explored the isles, making notes and collecting specimens as he went. Galápagos is
populated by a scant few species – creatures that randomly came upon the archipelago by wing,
by fin, or by washing up ashore, as the case probably was with the reptilian life. This scant
handful blossomed into a variety of unique species – if an ecological niche existed, it was
eventually filled by the hardy descendents of those marooned individuals. Finches and
mockingbirds thrive, each type having learned ingenious tricks for procuring certain food sources.
Iguanas have taken to land and sea, while the namesake giant tortoises have uniquely shaped
shells according to the food supply of their particular island. Raptors, such as hawks and owls,
prey upon dragons and stalk their victims like cats. Flowers bloom universally yellow in the brief
Galápagos spring because their sole pollinator option, the black carpenter bee, is attracted to
golden hues alone.
Darwin's observations, especially of the taxidermed mockingbird specimens that he took care to
label and categorize, sparked an epiphany that would lead to his publication of the monumental
book The Origin of Species in 1859. In all the years and hullabaloo that followed this
landmark text on the theory of evolution, Darwin always made one fact pointedly clear – that the
Galápagos islands were the source and inspiration of his findings.
Though the islands have been ravaged by man's actions for centuries – over 200,000 giant
tortoises were slaughtered for meat in a span of 200 years, for example – they have remained
largely the same due to their isolation, and their current protected status. 30,000 people, as well
as a variety of introduced plants and animals, live on the islands today. Thousands more come to
tour. Strictly enforced regulations keep the human interference at bay, and other measures –
like the intense eradication efforts to reduce the feral goat population – help to maintain the
fragile balance of native wildlife on this delicate microcosm of an ecosystem. And if we as a
species can demonstrate responsible stewardship of this unique jewel of a place, perhaps that
bodes well for the planet – and ourselves, as a whole.
Averaging around 20 Mbps, Galápagos sports an interlaced VC-1 encoding, even though the
packaging erroneously states it is formatted in full 1080p. The material was sourced at 1080i 50Hz
from the BBC, which was then converted to 1080i 60Hz for BD. The documentary looks
surprisingly good - much like its global scale cousin, Planet Earth. There is great care taken by the
filmmakers to capture an extraordinary amount of detail in their subjects, and extreme close-ups
are plentiful throughout. Every feather and rough, horned hide depicted has a fine amount of
detail, and every feature of a slender garden eel or minute goby fish is apparent, and makes for
excellent repeat viewing - if only to catch all the detail!
For all of its visual appeal, however, one can't help but wonder what this title might have looked like
had it been able to utilize a full 1080p, high-bitrate spec. The picture did not look digitally "scrubbed
clean," thank goodness, although there still seems to be an ever-so-slight amount of softness that's
likely attributed to an interlaced source. Galápagos has incredibly good picture quality
regardless, and I heartily recommend it.
Where Galápagos really falls short is with its audio offering - nothing more than a Dolby
Digital 2.0 option. While it sounds well enough, especially with the fairly generous amount of
narration by Tilda Swinton, it's really a shame that such a wonderfully produced documentary, on a
high definition format, has the sound of your average CD. Ambient effects especially would have
benefit from, at the very least, a DD 5.1 treatment; if not a lossless option, something rarely found
on minor BD releases like documentaries anyway.
As it is - and as would be expected - the audio presentation is very flat, with the sound feeling
condensed into too small a space. As mentioned previously, ambient effects would have added a
fuller and more immersive soundscape to the feature, and an LFE channel could have been an ideal
tool to add rumble and "oomph" to the ubiquitous roaring surf. It's a rather unfortunate decision,
what with Blu-ray's A/V capabilities, but given the educational nature of this title, it suffices well
enough.
It is incredibly intriguing how things tend to take root in the unlikeliest of places. Fiery, barren rock,
isolated hundreds of miles out into the ocean from the nearest continent, gives way to flourishing
life - when given a few millennia. Life forms that just happen upon a pristine, yet harsh,
environment adapt and thrive in time. And these humble rocks eventually inspired one young,
curious man into a grand epiphany that changed the way humanity looked at life on Earth forever.
The BBC has again done an excellent job of covering the natural wonders of our planet, and this
Blu-ray disc shows the Galápagos archipelago in a beautiful and almost ideal fashion. Its highly
unique and almost alien wildlife will fascinate and mesmerize. Its geologic phenomena and its fiery
heart are awe-inspiring. All around, this is a wonderful documentary and the Blu-ray, while not
perfect, is more than adequate to show off the beauty of these Pacific oddities.
BBC Video has announced that they will be releasing the nature documentary 'Galapagos' for Blu-ray on October 2. Riding the coat tails of the very successful 'Planet Earth' release, 'Galapagos' documents a group of island in which creation and extinction define ...
