HMRG Deep
The Sirena Deep, originally named the HMRG Deep, was discovered in 1997 by a team of scientists from Hawaii. Its directly measured depth of is third only to the Challenger Deep and Horizon Deep, currently the deepest known directly measured places in the ocean. It lies along the Mariana Trench, 200 kilometers to the east of the Challenger Deep and 145 km south of Guam. Formation The Sirena Deep was most probably formed, not through transform fault motion as previously thought, but through a north-south convergence of the Caroline plate and the Pacific plate, in which the Caroline plate is subducting. A group of scientists have hypothesized that the great depth of the Mariana Trench, the Challenger Deep, and the Sirena Deep is due to a tear in the subducting Caroline plate, causing deformation of the Pacific plate above. This tear would be located to the south of Guam, the same location of the deepest portion of the Mariana Trench. The tear would lead to unusual regiona ...

HAWAII MR1
The HAWAII MR1 is a seafloor imaging system developed by the Hawaii Mapping Research Group (HMRG) in 1991. HAWAII MR1 is short for HIGP (Hawaii Institute of Geophysics and Planetology) Acoustic Wide Angle Imaging Instrument, Mapping Researcher 1. This system is the first to use all-digital signal processing. See section titled HAWAII MR1/MR2. It has been used in the discovery of several objects and locations of note, examples being the USS ''Yorktown'' and the HMRG Deep. Description The MR1 system is relatively small and stable, and is towed at a depth of 80 to 100 meters. Because it is not hull-mounted, this data collection system has the ability to withstand rough conditions. The HAWAII MR1 also has the capability to measure and collect bathymetric and backscatter data simultaneously, and record raw acoustic data independently of human supervision. After collecting data, the data can be processed with software available from HMRG. The width of a scan produced by the system v ...

Geophysics
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.

University Of Hawaii
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

General Bathymetric Chart Of The Oceans
The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world’s oceans for scientists and others. Organisation GEBCO operates under the joint auspices of the International Hydrographic Organization (IHO). and the Intergovernmental Oceanographic Commission (IOC) of UNESCO. Its work is done by an international group of experts in seafloor mapping who develop a range of bathymetric data sets and data products. Data sets and products Although originally GEBCO published paper contour charts, today it has moved into the digital age and collects digital depths of the ocean from wherever they are available. GEBCO provides a range of bathymetric data sets and data products, including: *Global gridded bathymetric data sets: **GEBCO_08 G ...

CTD (instrument)
''For information about the CTD-rosette equipment package as a whole, see: Rosette sampler'' A CTD or sonde is an oceanography instrument used to measure the electrical conductivity, temperature, and pressure of seawater (the D stands for "depth," which is closely related to pressure). Conductivity is used to determine salinity. The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette. The sampling bottles close at predefined depths, triggered either manually or by a computer, and the water samples may subsequently be analyzed further for biological and chemical parameters. The CTD may also be used for the calibration of sensors. Measured properties The instrument is a cluster of sensors which measure conductivity, temperature, and pressure. Sensors commonly scan at a rate of 24 Hz. Depth measurements are derived from measurement of hydrostatic pressure, and salinity is measured from electrical conductivity. Sensors are arranged ...

Limiting Factor To Be Prepared For A Dive Into The Atlantic Ocean
In electronics, a limiter is a circuit that allows signals below a specified input power or level to pass unaffected while attenuating (lowering) the peaks of stronger signals that exceed this threshold. Limiting is a type of dynamic range compression. Clipping is an extreme version of limiting. Limiting is any process by which the amplitude of a signal is prevented from exceeding a predetermined value. Limiters are common as a safety device in live sound and broadcast applications to prevent sudden volume peaks from occurring. Limiters are also used as protective features in some components of sound reinforcement systems (e.g., powered mixing boards and power amplifiers) and in some bass amplifiers, to prevent unwanted distortion or loudspeaker damage. Types Limiting can refer to a range of treatments designed to limit the maximum level of a signal. Treatments in order of decreasing severity range from clipping, in which a signal is passed through normally but sheared off whe ...

Bathymetry
Bathymetry (; ) is the study of underwater depth of ocean floors (''seabed topography''), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetric (or hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths) and selected depths ('' soundings''), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwater depths. Seabed topography ...
