HADES-K - georeferenced macrofauna Dataset Description: <p>This dataset includes geo-referenced megafaunal counts from&nbsp;the Kermadec Trench,&nbsp;April/May 2014. The dives were in the Southwest Pacific, 4000 to ~10,000m from the RV/ Thomas G. Thompson during cruise TN309 (HADES-K), April - May 2014.</p> Methods and Sampling: <p>The HROV Nereus was used to conduct exploration and characterization (including downloading video seafloor transects) of the Kermadec Trench region in May 2014.&nbsp;&nbsp;Geo-referenced vehicle navigation was conducted using the R/V Thompson’s GPS launch position of the vehicle, the estimated initial on bottom position of the vehicle, the course over ground (determined by the Gyro heading, Doppler Velocity Profiler, and thruster speed).</p>
<p>The HROV transected between 1 and 5 meters off the seafloor, utilizing a down-looking Sony 4k HD camera system, in collaboration with the Advanced Imaging and Visualization Lab at the Woods Hole Oceanographic Institution.&nbsp; Megafauna was enumerated via direct counts from continuous video. Taxonomic identifications were based on comparison with published morphological characters when possible.</p>
<p>Nereus transect video was annotated using CADTV version 11 software and geo-referencing of continuous navigation was conducted via Matlab (2011 Release; MathWorks, Inc.) and Microsoft Excel for Mac 14.7.3.&nbsp;</p>

Controls on Hadal Megafaunal Community Structure: a Systematic Examination of Pressure, Food Supply, and Topography
<p><em>Extracted from the NSF award abstract:</em></p>
<p>Severe technical challenges associated with the extremes of hydrostatic pressure have prevented major advances in hadal ecological studies, and relegated hadal systems to among the most poorly investigated habitats on Earth. Through this project, Hadal Ecosystems Studies (HADES) program, PIs will determine the composition and distribution of hadal species, the role of hadal pressures (piezolyte concentrations, enzyme function under pressure), food supply (distribution of POC with the abundance and biomass of trench organisms, and metabolic rates/energetic demand), and depth/topography (genetic divergence and spatial connectivity of populations) have on impacting deep-ocean community structure. This project will examine these factors using the world's first full-ocean depth hybrid remotely operated vehicle (HROV) in conjunction with the only full-ocean depth imaging lander (Hadal-Lander). This project will provide the first seafloor data and samples in one of the world's best, yet little known trenches- the Kermadec Trench (SW Pacific Ocean). Megafaunal community structure and the relationship between POC and benthic bacterial biomass will be examined as a function of depth and location by systematic high-definition imaging and sediment/faunal sampling transects from abyssal to full trench depths both along and perpendicular to the trench axis. Population genetic approaches will provide levels of genetic divergence and evolutionarily independent lineages to assess the role of depth and topography in trenches and their adjacent abyssal plain in promoting the formation of species. Physiological constraints will be investigated by examining in-situ respiration of selected fauna and tissue concentrations of such protein stabilizers as trimethylamine oxide (TMAO), and the structural adaptations of macromolecules. </p>

dataset
<p>The HROV Nereus was used to conduct exploration and characterization (including downloading video seafloor transects) of the Kermadec Trench region in May 2014.&nbsp;&nbsp;Geo-referenced vehicle navigation was conducted using the R/V Thompson’s GPS launch position of the vehicle, the estimated initial on bottom position of the vehicle, the course over ground (determined by the Gyro heading, Doppler Velocity Profiler, and thruster speed).</p>
<p>The HROV transected between 1 and 5 meters off the seafloor, utilizing a down-looking Sony 4k HD camera system, in collaboration with the Advanced Imaging and Visualization Lab at the Woods Hole Oceanographic Institution.&nbsp; Megafauna was enumerated via direct counts from continuous video. Taxonomic identifications were based on comparison with published morphological characters when possible.</p>
<p>Nereus transect video was annotated using CADTV version 11 software and geo-referencing of continuous navigation was conducted via Matlab (2011 Release; MathWorks, Inc.) and Microsoft Excel for Mac 14.7.3.&nbsp;</p>

<p><strong>BCO-DMO Processing Notes:</strong>- concatenated all the dive data into a single dataset<br />
- added conventional header with dataset name, PI name, version date<br />
- modified parameter names to conform with BCO-DMO naming conventions<br />
- added columns for temp and altitude if not present in dive file<br />
- added date_start, obtained from PI submission, differs somewhat from HadesK_deploylog dataset<br />
- replaced blank cells with zeros to indicate that species were searched for but not found<br />
- changed 'COS' column header to 'COG' in dives 72, 73, 74.</p>

Sony 4k HD Imaging System with Deep-Sea Power and Light LED lights
PI Supplied Instrument Name: Sony 4k HD Imaging System with Deep-Sea Power and Light LED lights Instrument Name: Camera Instrument Short Name:camera Instrument Description: All types of photographic equipment including stills, video, film and digital systems. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/311/
PI Supplied Instrument Name: Instrument Name: HROV Nereus Instrument Short Name:HROV Nereus Instrument Description: Nereus is an efficient, multi-purpose “hybrid” vehicle that can explore and operate in the crushing pressures of the greatest ocean depths. An unmanned vehicle, Nereus operates in two complementary modes. It can swim freely as an autonomous underwater vehicle (AUV) to survey large areas of the depths, map the seafloor, and give scientists a broad overview. When Nereus locates something interesting, the vehicle’s support team can bring the vehicle back on board the ship and transforms it into a remotely operated vehicle (ROV) tethered to the ship via a micro-thin, fiber-optic cable. Through this tether, Nereus can transmit high-quality, real-time video images and receive commands from skilled pilots on the ship to collect samples or conduct experiments with a manipulator arm.
Technical specifications:
Weight on land: 2,800 kg
Payload capacity: 25 kg
Maximum speed: 3 knots
Batteries: rechargable lithium ion, 15 kilowatt hours in two pressure housings
Thrusters: 2 fore and aft, 2 vertical, 1 lateral (ROV mode) 2 fore and aft, 1 vertical (AUV mode)
Lights: variable output LED array, strobes
Manipulator arm: Kraft TeleRobotics 7-function hydraulic manipulator
Sonar: scanning sonar, forward look and profile, 675 KHz
Sensors: magnetometer, CTD (to measure conductivity, temperature, and depth)
Nereus supports a variety of science operations: Push coring, measuring heat flow, geotechnical and geochemical sensing, rock sampling and drilling, biological sampling, water sampling, high resolution acoustic bathymetry, and optical still and video imagery.
