Follow along with the international team of scientists during the 10-day Lost City 2005 Expedition as they conduct around-the-clock exploration of the recently discovered Lost City Hydrothermal Field (LCHF) and the surrounding region. Our team will use the NOAA research vessel (R/V) Ronald H. Brown and the Institute for Exploration's remotely operated vehicle (ROV) systems Argus and Hercules. The Lost City program brings together the excitement of investigating a submarine hot-spring system (like no other yet seen within the world's oceans) and new technology that allows shore-based scientists nearly 5000 mi away to conduct "sea-going" research in real-time via the underwater robotic systems and satellite transmissions. http://oceanexplorer.noaa.gov/explorations/05lostcity/welcome.html http://www.oceanexplorer.noaa.gov/include/images/ocean_explorer_podcast_100.jpg http://www.oceanexplorer.noaa.gov/explorations/05lostcity/welcome.html This 2005 expedition set a new benchmark in ocean exploration. Remarkable advances in technology allowed, for the first time, participation of an entire science party housed not on a research vessel, but instead in a Science Command Center located 4500 miles away. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/summary/summary.html View photos, slideshows and videos taken during the Lost City 2005 expedition. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/photolog/photolog.html As the ship prepares to leave the work site today, we again revisit some of the main, actively venting chimneys within the Lost City field. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july31/july31.html As we near the end of the cruise, we realize what remarkable views of the field the coupling of Hercules and Argus has provided us. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july30/july30.html If you lost something in an area of 645,000 square feet how would you find it? Find out how scientists are searching for a missing water sampler. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july29/july29.html Water sampling is a critical process to understanding the reactions taking place at Lost City. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july28/july28.html As we explore the Lost City, we want to learn if the animals at Lost City are unique and if the composition of the animals' communities is driven by the harsh chemical conditions of the Lost City habitats. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july27/july27.html How do the pilots know where Hercules is? Learn how the position of the NOAA ship Ronald H. Brown and the IFE ROVs Argus, and Hercules are kept track. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july26/july26.html Today we returned to the Lost City. We traveled around the main part of the field,collecting video, still images, samples of vent material, fluids, and a few animals. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july25/july25.html Hercules has completed the first dive. Watch as Hercules collects a sample from the Western Massif. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july24pm/july24pm.html Scientist watch as Hercules is prepared for it's first science mission to the Western Massif. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july24am/july24am.html The Ronald H. Brown arrived at the first study site. The first order of business was collect new bathymetric data of the dome-like mountain, referred to as the Western Massif. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july23/july23.html As the Ronald H. Brown cruises towards the Mid-Atlantic Ridge, technicians and scientists prepare for the first dive. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july22/july22.html Today the team, our team of scientists, began to gather at the University of Washington. Get acquainted with them as they describe their hopes and goals for this expedition. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july21/july21.html Follow our journey as NOAA's ship The Ronald H. Brown heads to the Mid-Atlantic Ridge to explore the white chimneys of the hydrothermal vent field known as Lost City. Includes slide show. http://oceanexplorer.noaa.gov/explorations/05lostcity/logs/july17/july17.html
