HADES-K - meiofauna raw counts Dataset Description: <p>This dataset includes raw counts of meiofauna identified in push core samples taken in the Kermadec Trench in the Southwest Pacific, 4000 to ~10,000m from the RV/ Thomas G. Thompson during cruise TN309, May 2014.</p> Methods and Sampling: <p>Push cores (6.35 cm diameter) of sediment were collected in situ using the manipulator arm of the Hybrid Remotely Operated Vehicle Nereus on the margin of the Kermadec Trench (6013m) and along the main trench axis (7137 to 9177m) at roughly 1000m increments.</p>
<p>Cores were sectioned at 1cm intervals and sieved for the meiofaunal fraction.</p>
<p>Meiofauna (&gt;300 microns) were enumerated and identified to major taxonomic groups (16 total) based on the published morphological descriptions of the taxonomic groups.&nbsp; The data present the total number of individuals in each of these groups in each core.</p>
<p>Attempts were made to obtain 3 replicate cores at each depth horizon (every 1000 meters from 6000m to 10,000m.&nbsp; For logistical reasons with vehicle performance (and loss at 10,000), all of the replicates were not able to be collected.</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>

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.

PI Supplied Instrument Name: Leica MZ APO stereo microscopes Instrument Name: Microscope - Optical Instrument Short Name: Instrument Description: Instruments that generate enlarged images of samples using the phenomena of reflection and absorption of visible light. Includes conventional and inverted instruments. Also called a "light microscope". Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/LAB05/
PI Supplied Instrument Name: PI Supplied Instrument Description:Push cores were borrowed from the National Deep Submergence Facility to be able to standardize results. The push cores were 6.35cm diameter). Instrument Name: Push Corer Instrument Short Name: Instrument Description: Capable of being performed in numerous environments, push coring is just as it sounds. Push coring is simply pushing the core barrel (often an aluminum or polycarbonate tube) into the sediment by hand. A push core is useful in that it causes very little disturbance to the more delicate upper layers of a sub-aqueous sediment.
