"[A] distillation of a decade of exploration, magnificently illustrated and eloquently written. Some will treasure World Ocean Census as a valuable reference, others as a place to find white-knuckle adventures."
-- From the foreword by Sylvia EarleAn insider's description of the comprehensive Census of Marine Life and what it reveals about a seriously threatened ecosystem.
The Census of Marine Life was launched in 2000 with the goal of producing the first-ever ocean census by 2010. Two thousand scientists from 82 nations agreed to the mandate to answer three important questions:
With the census nearing completion, scientists around the world will inherit critical data that will be studied for decades to come. This data will be a basis for answering such simple questions as "What will become of sharks, whales, reefs and salmon?"
This book deals with the adventures and experiences of the Census of Marine Life and the process of gathering the data, revealing the stories behind the science. The authors detail the most fascinating findings and exciting discoveries -- the thrills encountered and the difficulties overcome -- all illustrated with fabulous images captured during the project's explorations.
The text readily engages the reader, and the photographs are as beautiful as they are accurate. The information is comprehensive, compelling and current, and it represents an enormous group effort by some of the world's leading scientists.
The organization of the book follows the three-part census mandate. Individual sections focus on a range of topics, from the logistics of the census to the space-age technology used to project the uncertain future of the world's oceans. The book is fully illustrated and provides informative captions and sidebars of data.
World Ocean Census is a unique record of a monumental global undertaking, worthy of a wide audience with a variety of interests.

The only other place comparable to these marvelous nether regions, must surely be naked space itself ... where the blackness of space, the shining planets, suns and stars must really be closely akin to the world of life as it appears to the eyes of an awed human being, in the open sea half a mile down.
- William Beebe, HALF MILE DOWN
Until recently, many had the impression that the diversity of life in the sea was much lower than the complexity and richness of life on the land, especially tropical rainforests and temperate woodlands. It is easy to understand how this misconception arose -- largely because of the immense diversity of insects, especially beetles, altogether comprising about half of all the species thus far named that live on land. More important, humans are terrestrial, air-breathing creatures able to travel everywhere over the face of the land, even to the highest mountains, driest deserts and coldest polar regions, and thus are familiar with the various creatures great and small that live on land. Accessing the sea is more challenging.
Although the ocean comprises 99 percent of the biosphere and only 5 percent of that has been seen -- let alone explored -- it is little wonder that misconceptions have developed about the true nature of life on Earth. Fortunately, new technologies enhance our ability to find and document life from sunlit reefs to the deepest, darkest seas -- and the results are magnificently portrayed in this volume. Great challenges remain, but those involved with the Census of Marine Life have made giant strides in evaluating the nature of the past, present and future of life in the sea, and thus of life on Earth.
Far from being monotonous empty space, as some have long believed, the ocean everywhere is alive. In a single swirl of salt water, a plankton-feeding whale shark may swallow the larval or adult stages of 15 or more phyla (or divisions) of animals -- as many as all terrestrial phyla of animals combined. That single gulp also will likely contain a dozen or so phyla of Protists, including minute photosynthetic forms that do much of the heavy lifting in terms of generating oxygen and transforming water combined with carbon dioxide into food. Then there are the microbes. Thousands of new species are being discovered in nearly every sample of seawater being analyzed with current techniques, from bacteria to members of the kingdom Archeae, discovered late in the 20th century. It is not just the small creatures that have gone unnoticed. New families as well as new genera and species of coral, sponges, echinoderms, annelids and others are turning up on nearly every dive below a thousand feet or so. When biologist-diver-explorer Richard Pyle ventures into the almost-light almost-dark region of the sea known as "the twilight zone," he finds new fish species at the rate of about seven per hour of observation.
Given the magnitude of new discoveries, and the vast areas of ocean yet to be explored, it is clear that the unknown species of marine life far exceed the 250,000 or so now accounted for. So, how many kinds of plants, animals, microbes and other forms of life are in the sea? Estimates range from a million to one hundred million, making the goal of the Census of Marine Life -- taking stock of the diversity of life in the sea -- one of the most ambitious undertakings in the history of humankind. In effect, it means exploring, analyzing and making some kind of systematic sense of most of life on Earth. It is a daunting but worthy goal, vital, in fact, if humankind is to achieve an understanding of the natural systems that make life on Earth possible.
The importance of the Census is made urgent because at the same time that more is being learned about the diversity of life in the sea than during all preceding history, more is being lost. Jacques Cousteau's personal perspective -- from pioneering dives in the 1950s in pristine seas to an era a few decades later of "paradise lost" -- inspired the world to take notice, and to act. It is not just the obvious decline of marine mammals, seabirds, fish and other wildlife owing to deliberate or incidental killing of ocean wildlife for food and products, although some, such as the Caribbean monk seal, last seen in 1952, have been eliminated thus. Numerous creatures have a narrow home range, and when their habitat is destroyed, they are lost as well. Species endemic to specific coral reefs, to individual seamounts and to highly specialized associations, such as barnacles that live only on one kind of turtle or whale or crab, are especially vulnerable. Changes in ocean temperature and chemistry through human actions, now including acidification, are causing comprehensive shifts of geological magnitude on the global environment, and in turn on the species that comprise the countless bits and pieces that make up the whole.
No one can be certain of what the consequences will be of the damage that humans have wrought to the underpinnings of what has made Earth a hospitable place for our species. No one will ever know how many kinds of creatures have been or will be destroyed as a consequence of these changes. But it is clear that maintaining the diversity of life, from individual species to large ecosystems, is the key to resilience, to holding the planet steady through the trauma of rapid climate shifts and the other unprecedented changes that are upon us. At present, about 12 percent of the land is invested in national parks and preserves, worldwide, protecting the diversity of terrestrial and freshwater species and systems while but a fraction of 1 percent of the ocean is similarly safeguarded.
In an exceptional model of international cooperation targeting a singular goal, more than two thousand Census of Marine Life scientists have delved into past records, dived into modern oceans, and extrapolated future scenarios. Together, they have yielded a priceless gift: enhanced understanding of the nature of life in the sea and its importance concerning all that humans care about -- health, the economy, security and, most important, a planet that works in our favor. A distillation of their Herculean decade of exploration is contained here, magnificently illustrated and eloquently written by the authors and contributors.
Some will treasure World Ocean Census as a valuable reference, others as a place to find white-knuckle adventures. The images alone will cause many to re-evaluate their concepts of what astonishing forms are embraced within the bounds of what constitutes an eye, a heart, a body of living tissue. The underlying similarities shared by all living things -- humans very much included -- shine through, while maintaining wonder at the infinite capacity for diversity: from the broad divisions of life to the individual speckles and shapes that distinguish each sardine, salp and starfish from every other of its kind. Above all, the breakthroughs in knowledge gained, and awareness of the magnitude of what remains to be discovered, inspire hope that the greatest era of ocean exploration -- and ocean care -- will now begin.
Unlocking the Mystery of What Lives Below the Surface of the Global Sea
For thousands of years, indigenous traditions have described the ocean as the mythological birth place of life on Earth, a mysterious place filled with life-sustaining forces. In an ancient myth of the Yurok Indians of California, two great beings, Thunder and Earthquake, worked together to create the ocean and fill it with water. The animals came to live there because of its beauty. Their story speaks of seals that came to the newly formed ocean "as if they were thrown in by handfuls." Looking upon the ocean basin they had made -- vast, deep and full of water -- Earthquake and Thunder were satisfied that their job was done. The ocean was large enough to provide sustenance for all of Earth's creatures.
It is not surprising that the ocean has long fascinated humankind. Earth is the only planet known to have liquid water at the surface, and very little of the ocean has been scientifically investigated. However, there are accepted theories about its formation and composition and even some consensus about how it works, despite the lack of comprehensive data. Most scientists believe that the first, shallow oceans formed between 4 billion and 3.5 billion years ago. As the molten-hot newly forming crust of Earth cooled, it gave off great volumes of steam and water vapor, which in turned caused clouds to form and rain to fall. The rain carried salts and other elements from Earth's cooling surface into shallow depressions or basins in the crust. Before an ocean could form, the temperature had to fall to below 100 degree Celsius, the boiling point of water, so that the liquid could remain stable.
Over time and through complex geological processes, cooled crustal plates formed over the more molten interior mantle, and the ocean basins deepened. As the plates slowly circulated over the molten mantle, they drew together and were pulled apart over and over again, eventually forming Earth's first supercontinent -- a single landmass consisting of all the modern continents -- Vaalbara. Believed to have formed between 3.6 billion and 3.3 billion years ago, it was surrounded by a vast sea. As this early supercontinent broke apart and the crustal plates continued their journey, the configuration of the ocean changed as well. As we know it today, the world's ocean accounts for roughly 71 percent of our planet's surface and 99 percent of its inhabitable volume; its average depth is approximately 3.8 kilometers (close to 2.4 miles).
Scientists are still trying to unravel one of the greatest mysteries of Earth: when did "life" first appear and how did it happen? The scientific community has been debating the timing and mechanisms of the origin of life for many years. However, most agree that the earliest life-forms evolved in the ocean, most likely as primitive, one-celled forms that appeared about 3 billion years ago. This primitive life was all that existed for approximately the next 2 billion years. Then a profusion of multicellular life exploded, in incredibly complex forms, and began to fill the oceans. As some marine species became able to live on land, new and increasingly complex forms of life began to appear all over the planet.
Many of the microscopic life-forms, or microbes, that currently live in the ocean may be similar to Earth's early life, and their abundance is extraordinary. Microbiologist Mitch Sogin and his team at the Marine Biological Laboratory at Woods Hole, Massachusetts, discovered more than 20,000 kinds of microbes in a single liter (about 1 quart) of seawater; previous research had led them to expect only 1,000 to 3,000. "Peering through a laboratory microscope into a drop of seawater is like looking at the stars on a clear night," says Census marine microbiologist Victor Gallardo, of Universidad de Concepción, Chile. "New DNA tag-sequencing technology increases resolution much like the Hubble Telescope did for space. We can see marine microbial diversity to which we were blind before. These rare ancient organisms are likely to prove a key part of nature's history and strategy."
The current average salt content of this cradle of life is approximately 35 parts to 1,000 parts of ocean water. Some scientists estimate that the oceans contain as much as 50 quadrillion (50 million billion) tons of dissolved solids, mainly dissolved salts such as sodium chloride. If the salt in the sea were removed and spread evenly over the earth's land surface, it would form a layer more than 150 meters (500 feet) thick, about the height of a 40-story office building! Salts become concentrated in the sea because the sun's heat evaporates almost pure water from the ocean surface, leaving the salts and salty water behind. This process is part of a continual exchange of water between the earth and the atmosphere called the hydrologic cycle.
The salinity of ocean water varies. It is affected by such factors as melting ice, inflow of river water, evaporation, rain, snowfall, winds, wave motion and ocean currents that cause horizontal and vertical mixing of the saltwater. Small changes in salinity can greatly affect ocean life. Some organisms can tolerate wide swings in salinity, while others, such as many corals, can tolerate only narrow salinity ranges. The saltiest water occurs in the Red Sea and the Persian Gulf, where rates of evaporation are very high. Of the major ocean basins, the North Atlantic is the saltiest. Low salinities occur in polar seas, where the salt water is diluted by melting ice and frequent precipitation.
Salinity is not the only variable that affects marine life. Other parameters include temperature, available nutrients, currents, winds, storms and ice. To fully comprehend how species survive in the ocean, it is important to understand how the ocean works. Important unanswered questions remain about the interdependency of oceanic parameters, such as how winds affect currents, how currents affect the temperature and flow of nutrients, and how nutrients control productivity. The limits to our current understanding can be overcome only by further ocean exploration -- by initiatives such as the Census of Marine Life that are investigating the biology of the global ocean and how its physical properties affect its inhabitants.
Launched in 2000 with the goal of producing the first-ever ocean census by 2010, the Census of Marine Life brought together 2,000 explorers from 82 nations to answer three important questions: What once lived in the global ocean? What is living there now? What will live there in the future? So little is known about what lives below the surface in the global ocean that the Census is much like a space program; it too has inherent challenges and dangers, and likewise generates excitement about exploring the unknown. To reach the depths of the global ocean -- as deep as 11 kilometers (7 miles) below the surface -- requires equipment that is just as sophisticated as the technology used to explore the outer reaches of the universe. Unlike space programs, however, underwater technology has only recently become advanced enough to allow explorers a fish's-eye view of what lives in the deepest, darkest, coldest reaches of the ocean.
Census of Marine Life scientists have been working at the cutting edge, using new technology to explore previously unreachable places and capturing images of the incredible life-forms -- everything from blind lobsters to worms that live without oxygen -- that exist at the bottom of the sea. This book provides an inside look at their many adventures, reveals their findings and shares the fabulous images they have captured as they unlock the mystery of what lives below the surface in the wondrous global sea.
The excitement of discovery, particularly the almost constant revelation of species new to science, shines through what could have been dry reportage, and numerous photographs, many of the new species, illuminate the text.

The Census of Marine Life is a global network of scientists in more than 80 nations involved in a ten-year project to assess and explain the diversity of life in the oceans. On first examination, this appears to be a typical oversize book dedicated to beautiful underwater photography; however, in well-written text, [the authors] describe the various aspects of the Census for the educated layperson. Illustrated with examples of creatures found in all parts of the oceans, including many newly discovered and never-before-described species, chapters cover the different project groups, how they are gathering and publishing data, and why this is important. Several one- to four-page inserts explain such concepts as hydrothermal processes and the global ocean current conveyor belt.... This will appeal to readers attracted to nature photography as well as anyone interested in the ocean, science, or global climate change. Also useful for high school or college courses on climate, oceanography, or biology.

About the only corner of the planet neglected by [a] world atlas, the ocean teems with hidden stories uncovered in this first-ever census of marine life... The survey reveals some of those hidden denizens of the deep, from the vampire squid to the flamingo tongue snail to the shoulderbar soldierfish, each as exotic-looking as their names. Census scientists have tagged seals, salmon and sooty shearwater shorebirds with transmitters to follow migrations. Arctic and Antarctic expeditions reveal changing populations under the pressure of a warming ocean. And everywhere looms the threat of extinction for overfished seafood stocks. "Above all, the breakthroughs in knowledge gained, and awareness of the magnitude of what remains to be discovered, inspire hope that the greatest era of ocean exploration - and ocean care - will now begin.
- Dan Vergano USA Today 2009 12 12
World Ocean Census is a gorgeous book that would make a great gift for someone who enjoys the ocean or works in a related field, or a great book to have on your own shelf as a reference.
- Jennifer Kennedy about.com 2009 12 01
The book is at its best when it offers glimpses of the astonishing array of sea creatures revealed by the survey. It includes critical data that will be studied for decades to come....Hundreds of breathtaking, full-color photographs plunge one deep into the ocean to see some of the millions of species - from the smallest microbes to the largest whales - that dwell beneath the waves.

The World Ocean Census is compilation of a 10-year research effort into examining marine life.... Overall, this is an attractive book and it is modestly priced. Most general readers will find topics of interest.
- Ralph Lee Scott American Reference Books Annual 2009
The book is at its best when it offers glimpses of the astonishing array of sea creatures revealed by the survey... [It] is full of high-quality photographs [that] reveal strange, recently discovered species... Fittingly, World Ocean Census begins and ends with spectacular photos of jellyfish, which are supremely suited to exploiting the niches created by overfishing. How humans respond to the trends revealed by the census will largely determine whether this 'jellification' of the ocean will continue, or if crippled marine populations may have a chance to recover.
- Mark Schrope Nature Vol 462/19 2009 11 01
[starred review] As industrial fishing fleets have mined the seas of life before scientists get a chance to study it, an international consortium of scientists, funded by their governments, began a collaborative effort in 2000 to catalog every living organism living in the global ocean. Scientists voyaged to regions that had never been studied before, such as the Gaskel Ridge in the Arctic, where unique hydrothermal vent communities were found, while others researched the human history of marine resource management to get an idea of pre-industrial ocean life... Glorious photographs, full of amazing forms and colors, capture many creatures readers will find entirely unfamiliar, as well the cutting-edge technology used to uncover them. Science writer Crist, along with scientists Scowcroft and Harding, have produced a highly readable text with stunning photos that should fully engage the public imagination, a fitting and accessible prelude to the full scientific report, due in 2010.
- Publishers Weekly 2009 09
The articles are written in an open and accessible style.
- A. Hauge Journal of the Norwegian Medical Association 2010 07 01
The general public, students, and even scientists interested in getting up to speed on the latest will find this book a captivating read. I would like to think that every high school library would have a copy of the book and that advisors would bring it to the attention of students contemplating a career in things oceanic. The works of William Beebe, Rachel Carson, and Jacques Cousteau inflected the careers of past and present marine scientists; this book promises a future in studies of the global ocean that those pioneers could never have envisioned.
