Portable observatories and new marine vehicles: The hinge of historic change in deep sea exploration Five hundred vents newly discovered off the US West Coast, each bubbling methane from Earth's belly, top a long list of revelations about "submerged America" being celebrated by leading marine explorers meeting in New York. "It appears that the entire coast off Washington, Oregon and California is a giant methane seep," says RMS Titanic discoverer Robert Ballard, who found the new-to-science vents on summer expeditions by his ship, Nautilus. The discoveries double to about 1,000 the number of such vents now known to exist along the continental margins of the USA. This fizzing methane (video: http://bit. ) is a powerful greenhouse gas if it escapes into the atmosphere; a clean burning fuel if safely captured. "This is an area ripe for discovery," says Dr. Nicole Raineault, Director of Science Operations with Dr. Ballard's Ocean Exploration Trust. "We do not know how many seeps exist, even in US waters, how long they have been active, how persistent they are, what activated them or how much methane, if any, makes it into the atmosphere." Further research and measuring will help fill important knowledge gaps, including how hydrocarbons behave at depth underwater and within the geological structure of the ocean floor. Expeditions this year include also NOAA's Deepwater Exploration of the Marianas Trench - a 59-day voyage with 22 dives into the planet's deepest known canyons in the Pacific Ocean near Guam. NOAA explorers added three new hydrothermal vents to the world's inventory and a new high-temperature "black smoker" vent field composed of chimneys up to 30 meters tall - the height of a nine-story building. Also revealed: a tiny spot volcano (the first ever discovered in US waters), a new mud volcano, thick gardens of deep-sea corals and sponges, a rare high-density community of basket stars and crinoids (a living fossil), and historic wreckage from World War II. (Photo, video log: http://bit. ) Scores of spectacular, rare and sometimes baffling unknown species encountered on this year's first-ever voyages to new deep ocean areas include several purple animals such as: Beyond being spectacularly photogenic, such animals help scientists better understand the web of life that sustains all species, including humans. As well, understanding how "extremophile" lifeforms survive in such conditions (piezophiles, for example, thrive in high pressure; pyschrophiles, aka cryophiles, live in water as cold as ?20 °C, as in pockets of very salty brine surrounded by sea ice), is usefully relevant to food and pharmaceutical preservation technologies, medical technology, nanotechnology and energy science. Dr. Ballard and about 100 other leading figures in marine science meet Oct. 20-21 to compare thoughts on the future of marine exploration at the 2016 National Ocean Exploration Forum, "Beyond the Ships: 2020-2025," hosted in New York by The Rockefeller University in partnership with Monmouth University. The Forum is also supported by the Monmouth-Rockefeller Marine Science and Policy Initiative, NOAA, the Schmidt Ocean Institute, and James A. Austin, Jr. Ocean exploration has arrived at a historic hinge, Forum organizers say, with profound transformation underway thanks to new technologies, led by increasingly affordable "roboats" - autonomous or remotely controlled vehicles that dive into the ocean or ply the surface laden with sensors collecting information from instruments suspended beneath them. ROV SuBastian, for example, is a new eco-friendly 3,100 kg (6,500 pound) deep-sea research platform for the Schmidt Ocean Institute's R/V Falkor, equipped with ultra high-resolution 4K cameras, mechanical arms that move seven ways and can sample to depths of 4,500 meters (2.8 miles), with a lighting system equivalent to the lamps of 150 car high-beams. (SuBastian sea trials video: http://bit. High-res photos, b-roll: http://bit. ). Says Wendy Schmidt, co-founder of Schmidt Ocean Institute: "With ROV SuBastian we will help make life on the ocean floor real to people who will never visit the sea, so they, too, can begin to appreciate the importance of ocean health and make the connection between life in the deep sea and life on land." "You don't have to be a scientist at sea to recognize the importance of the marine environment, and we are only at the beginning of our understanding. We never anticipated discovering the world's deepest living fish, the ghostfish (video: http://bit. ), back in 2014, and are excited about the life we will discover next." ROV SuBastian will have that opportunity this December during its first science cruise, in the Mariana Back-Arc in the western Pacific. (Cruise details: http://bit. . All dives will be live-streamed on Schmidt Ocean Institute's YouTube page: http://bit. ). Contributing as well to the transformation: Modern communications and sampling techniques, including eDNA, big data analysis and other high-tech advances that automate and vastly accelerate the work, opening the way for experts and the public to reach, see, chart, sample and monitor formerly secret depths of the seas. Innovations include portable observatories for underwater monitoring and a "curious exploration robot," programmed to focus on everything unfamiliar to its data bank brain (photo: http://bit. , video: http://bit. , credit WHOI). According to innovator Yogesh Girdhar of the Woods Hole Oceanographic Institution, in a recent test off the Panama coast, a similar swimming robot discovered a startlingly enormous population of crabs. Other engineers, meanwhile, are developing "game changing" unmanned undersea and surface vehicles tricked out with an array of sophisticated sensors to perform a suite of underwater tasks, enabled to run for months by recent improvements in battery technology. (See video, for example, of Boeing's 51-foot Echo Voyager: http://bit. ). Such "roboats" can be programmed to conduct deep sea exploration or searches using a lawn mower pattern, surfacing regularly to report data back to shore via satellite, or to patrol a coastal area, returning to port after one or two months to recharge and redeploy. These technologies will enable today's generation to "explore more of Planet Earth than all previous generations combined," predicts Dr. Ballard, whose celebrated career will be recognized at the Forum with the Monmouth University Urban Coast Institute's Champion of the Ocean award. The technologies will not only help discover and monitor new mineral and living resources, they could help secure interests vital to the world's economy or identify the best paths for communications cables that span the ocean floor - the veins of the Internet. Until recently, ocean exploration has involved ships operated like fishing vessels, dipping sensors and hauling up data. Forum participants such as John Kreider of Oceaneering International envision such ships in future serving as hives from which flotillas and squadrons of autonomous underwater, surface and aerial vehicles are launched - robots guided by experts on board or remotely, such as from a distant university campus via "telepresence," returning with images and data orders of magnitude larger than ever before. Thanks to modern communication technologies, schoolchildren, their teachers and indeed any interested members of the public can, and do, now follow expeditions online in real time. Among the many compelling interests and pursuits of marine scientists and historians in the public, private and military sectors: Says scientist James (Jamie) A. Austin, Jr. of the University of Texas, "the slow, time consuming and expensive way we've done ocean exploration forever - one ship doing one task at a time - is giving way to autonomous systems that net massive hauls of data, with advances in big data analysis enabling scientists to make sense of it rapidly." Dr. Austin envisions installations on the seafloor - measuring tremors or helping scientists estimate the rate at which Earth swallows carbon into its mantle through plate tectonics, for example - with data delivered by a device periodically flying up and down to the surface. Simply mapping the ocean floor is an important goal. While satellites have fully charted the seafloor in low resolution, only 10% is mapped in detail. At an estimated cost of $2.9 billion - or about $9 per square kilometer ($23 per square mile) - a "Gurgle Earth" map of the deep oceans could be completed at high resolution using swath like, multi-beam sonar. The hazard of uncharted oceanic mountains, trenches, volcanoes and other features was dramatically underscored in 2005 when a nuclear attack submarine, the USS San Francisco, struck a seamount in the Pacific at high speed, killing one crew member and injuring 97. Over 50% of US territory lies beneath the ocean surface and such mapping could also expand American territorial and resource claims. With documentation of the continental shelf, America's Exclusive Economic Zone, 11.3 million square km in size today, could extend a further 2.2 million square km - a 20% enlargement, representing an underwater area larger than Alaska. (See http://bit. ). Other recent finds of ancient shipwrecks and even ancient human remains, he adds, reveal that early mariners didn't simply hug the coastline but sailed courageously great distances from shore, and make it possible to determine who they were. While these and countless biological discoveries represent things discovered underwater, the intent of future exploration campaigns include measuring more, sampling more, and better understanding physical, geological and living processes - knowledge of vital importance for security, responsible ocean use and sustainable resource management. Asked what he thought might yet be discovered underwater, Dr. Ballard compares that to asking Lewis or Clark what they thought they'd find on their historic traverse of America. The reply, he says, would have been "I don't know. I'm getting into a canoe and I'm going to paddle." In one of several papers written for the Forum, meanwhile, U.S. Ambassador Cameron Hume adds that, beyond exploring and the initial characterization of an ocean area, humanity also needs to pursue subsequent research and long-term observing. In his paper, Dr. Jerry Schubel of the Aquarium of the Pacific, lamenting the relatively low level of public attention accorded to ocean exploration, points to new opportunities for awareness raising created by social media. "Understanding life on other planets," he says, "may help us understand the origins of life in the universe, but it can't match the relevance and importance of ocean exploration to the future of life on this planet." Says organizer Prof. Jesse Ausubel, faculty member at The Rockefeller University: "SuBastian and the Roboats sounds like a rock band, but it is the future of ocean exploration. One million marine species and one million shipwrecks may remain to be discovered. Let's use new approaches to multiply exploration." Says Forum organizer Vice Admiral Paul Gaffney, former President of Monmouth University and Urban Coast Institute Ocean Policy Fellow: "America is the greatest maritime nation in the history of the world, yet we scarcely know submerged America and only about 10% of the global oceans. At this Forum, we are encouraging ocean technology leaders to join the discussion and support more comprehensive exploration campaigns indispensable for sustainable use of the oceans and inspiring ocean stewardship." The ultimate aim: to formulate compelling, feasible campaigns to be carried out by the participants in the 2020-2025 timeframe. At the Forum, Dr. Jyotika Virmani will share the roster of teams for the $7 million Shell Ocean Discovery XPRIZE, a global competition to promote unmanned ocean exploration. In a letter to the Forum (in full: http://bit. ), the President of the US National Academy of Sciences, famed ocean explorer Marcia McNutt, says "a number of events have underscored how essential our mission is to vastly improve knowledge of the marine environment." Inadequate knowledge of ocean terrain and currents hampered the search for flight MH 370 in 2014, for example. CubeSats, she notes, have "'democratized' space, providing access for pennies on the dollar. Similarly, new commercial tools, although still in their infancy, hold the promise of ushering in the citizen science era of ocean exploration." "The task we face is simply too large to continue to use 20th century tools if we hope to make a dent in the problem."

The Forum is the latest in a series mandated by Congress (Title XII of Public Law 111-11) in March 2009 when it officially established the NOAA ocean exploration program. This law requires NOAA to consult with the other federal agencies involved in ocean exploration, as well as external stakeholders, to establish a "coordinated national ocean exploration program" that promotes data management and sharing, public understanding, and technology development and transfer. The law also requires NOAA to organize an "ocean exploration Forum to encourage partnerships and promote collaboration among experts and other stakeholders to enhance the scientific and technical expertise and relevance of the national program." The 2016 Forum convenes approximately 100 experts from academia, government, and the private sector to discuss adaptation and integration of technologies that can be employed in ocean exploration campaigns in the 2020-2025 timeframe. The Forum will look to a future of expanded exploration activities by making more platforms capable of measuring, sampling, or imaging yet-to-be-explored areas - employing a suite of technologies that have been dubbed "flyaway systems." Expanding spatial coverage and reducing cost of data collection are key ocean exploration priorities over a ~10 year time horizon. These priorities can be realized by creatively adapting and assembling existing technologies, and deploying them onboard autonomous devices, buoys, various so-called ships-of-opportunity, and other platforms, in addition to the existing fleet of dedicated ocean exploration vessels. The Forum will help federal funding agencies and foundations define and prioritize exploration technology investment options for 2020-2030, and stimulate a vision among leading explorers of what it might be like to conduct expeditions in this time frame.

COPENHAGEN (Reuters) - Scientists have found 500 seabed vents bubbling methane into the Pacific Ocean off the United States, roughly doubling the number of known U.S. seeps of the powerful greenhouse gas, a study showed on Wednesday. Methane naturally escapes from the sea floor in many places around the world and can stoke global warming if it reaches the atmosphere. Worldwide, scientists are trying to see if rising ocean temperatures cause more leaks. "It appears that the entire coast off Washington, Oregon and California is a giant methane seep," Robert Ballard, who is famed for finding the wreck of the Titanic and has now discovered the 500 new seeps, said in a statement. "The discoveries double to about 1,000 the number of such vents now known to exist along the continental margins of the USA," the statement said. Nicole Raineault, Director of Science Operations with Ballard's Ocean Exploration Trust, said it was unknown how long the seeps had been active, what triggered them and how much, if any, of the gas reached the atmosphere. Gunnar Myhre, an expert at the Center for International Climate and Environmental Research in Oslo, said research in Arctic waters off Norway's Svalbard archipelago indicated that most seabed methane there dispersed in the water. And when seeps are found "it's most likely that they've been occurring for a long time," he told Reuters. No one has had technology to map seeps until recent decades. About 100 experts will meet on Oct. 20 and 21 for a U.S. National Ocean Exploration Forum in New York, hosted by The Rockefeller University in partnership with Monmouth University. The scientists hope to promote more research into marine science after recent finds of creatures including a purple sea cucumber and a tiny "Mud Monster" in the deep Pacific by the U.S. National Oceanic and Atmospheric Administration. "One million marine species and one million shipwrecks may remain to be discovered," Jesse Ausubel, of the Rockefeller University, said in a statement.

The reduction of aggressive behaviors can be a concern whenever animals are socially housed, but for some species, such as marabou storks, zoos are still unsure of the best management strategies. To learn more about marabou behavior and how dynamics change as group composition changes, we monitored a total of 3.5 marabous as individuals were added and removed over 2 years. We found that, in mixed-sex groups, males were more likely to be the initiators of displacements and females were more likely to be the recipients. Most contact aggression was intra-sexual, and females engaged in contact aggression more often than males. The highest levels of aggression were seen in our all-female groups, which was unexpected given the high number of male attacks on females reported in zoos. Because females were being added and removed but our males remained the same throughout the study, we are unsure whether this was due to a higher level of instability among females or a true sex difference; regardless, these data highlight the need to monitor aggression even within all female stork groups. Overall, we observed low levels of inter-sexual aggression, suggesting that some fatal attacks may be due, in part, to non-social factors, such as enclosure design. Social birds like marabous may benefit from the same type of group management approach that is commonly utilized with other social taxa. A two-pronged approach of observation and management of marabou social dynamics and some modification of their enclosure structure may limit injurious aggression in the future. © 2014 Wiley Periodicals, Inc.

Taveta golden weavers are popular in zoos, but little has been published on their reproduction, social behavior, or other aspects of their management. At Disney's Animal Kingdom®, we have had great success with our breeding program and house a large flock in our mixed-species walk-through Africa aviary and smaller groups in the off-exhibit Avian Research Center. We conducted observations on both groups in order to document behavioral differences between the groups living under differing management conditions. Data on which individuals were inside, on or near focal nests were collected using a 30-s scan samples. Scan data were analyzed using a two-factor ANOVA, with aviary location and nest contents as the factors. We found that, in both aviary locations, females spent more time inside and on the nests than males did. As expected, females spent more time inside the nests containing eggs and more time on the nests containing chicks, likely due to incubation and chick-feeding demands, respectively. Interestingly, we found that females spent significantly more time inside their nests and males spent more time near their nests in the Africa aviary than in ARC. Despite Africa aviary's higher nest attendance, a higher proportion of nests fledged chicks in ARC (72% vs. 41%). These data are consistent with findings in wild sociable weavers [Spottiswoode, 2007. Oecologia 154: 589-600]. Future work with zoo-housed populations of weavers could help shed light on this phenomenon, which is not yet well understood. A better understanding of the consequences of different group sizes and housing conditions could have important implications for how Taveta weavers are managed. © 2015 Wiley Periodicals, Inc.
