attribute NC_GLOBAL instruments_0_description String Remotely operated underwater vehicles (ROVs) are unoccupied, highly maneuverable underwater robots operated by a person aboard a surface vessel. They are linked to the ship by a group of cables that carry electrical signals back and forth between the operator and the vehicle. Most are equipped with at least a video camera and lights. Additional equipment is commonly added to expand the vehicle’s capabilities. These may include a still camera, a manipulator or cutting arm, water samplers, and instruments that measure water clarity, light penetration, and temperature. More information.

attribute NC_GLOBAL instruments_1_description String The BioSonics DT-X Digital Scientific Echosounder is available in single or spilt beam configuration. The resultant data set comprises 38 and 120 kHz split beam data.  The DT-X Digital Scientific Echosounder is used for stock assessment, biomass estimates, and habitat mapping. DT-X digital transducers are available in a range of frequencies (38, 70, 120, 200, and 420 kHz) and beam patterns in split beam or single beam. Up to 5 transducers can be mulltiplexed for simultaneous data collection in any combination of frequencies and transducer orientations. The BioSonics split beam echosounder data can be analyzed for fish quantity, individual sizes, direction of travel through the acoustic beam.  Data analysis is done using BioSonics, Echoview, or Sonar4/5-Pro software (and other options are available). Additional information is available from: BioSonics DT-X Digital Echosounder (http://www.biosonicsinc.com/product-overview.asp), BioSonics (http://www.biosonicsinc.com), Echoview (http://www.echoview.com/), and Sonar4/5-Pro (http://tid.uio.no/~hbalk/sonar4_5/index.htm).

attribute NC_GLOBAL projects_0_acronym String McMurdo Predator Prey
attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:\nThe research project investigates the importance of top down forcing on pelagic food webs. The relatively pristine Ross Sea includes large populations of upper-level predators such as minke and killer whales, Adélie and Emperor penguins, and Antarctic toothfish. This project focuses on food web interactions of Adélie penguins, minke whales, and the fish-eating Ross Sea killer whales, all of which exert foraging pressure on their main prey, crystal krill (Euphausia cyrstallorophias) and silver fish (Pleuragramma antarcticum) in McMurdo Sound.\nThe investigators used a video- and acoustic-capable ROV, and standard biological and environmental sensors to quantify the abundance and distribution of phytoplankton, sea ice biota, prey, and relevant habitat data.  The sampling area included 37 stations across an 30 x 15 km section of McMurdo Sound, stratified by distance from the ice edge as a proxy for air-breathing predator access. This study will be among the first to assess top-down forcing in the Ross Sea ecosystem and will form the basis for multidisciplinary studies in the future.\nMap sampling stations

attribute NC_GLOBAL summary String Krill and fish were sampled acoustically and visually beneath the fast ice\nusing the tethered SCINI ROV, which was deployed and operated through a 25 cm\ndiameter hole drilled through the sea ice. SCINI contained cameras and\nthrusters, and towed a sensor package consisting of a WET Labs fluorometer\n(ECO-AFL/FL) and a single-beam Biosonics 120 kHz DT-X echosounder. Visual\ntargets were identified to the lowest taxon possible; these observations were\nused primarily to verify classification of acoustic signals. The echosounder\noperated at a nominal ping rate of 1 ping s-1; however, this rate was\noccasionally adjusted if false bottom signals were observed. The general\nprofile of a dive included a surface transect of ~300 m horizontal distance,\nwhere the acoustic transducer faced downward, and also a dive to ~120 m if\nconditions allowed. Echogram data were saved to a depth of 500 m, and\nbackground noise was removed. Given the effective range of the transducer of\napproximately 100 m (resolving -80 dB targets), surveys characterized the\nupper 200 m of the water column.
