R/V ''Roger Revelle'' is a operated by Scripps Institution of Oceanography under charter agreement with Office of Naval Research as part of the University-National Oceanographic Laboratory System (UNOLS) fleet. The ship is named after Roger Randall Dougan Revelle, who was essential to the incorporation of Scripps into the University of California San Diego. Construction and characteristics ''Roger Revelle'' was built by Halter Marine Inc., Gulfport, Mississippi. She was laid down on 9 December 1993 and launched on 20 April 1995. She was delivered to the U.S. Navy 11 June 1996, as RV ''Roger Revelle'' (T-AGOR-24), a ''Thomas G. Thompson''-class oceanographic research ship. Her maiden voyage was from Gulfport to San Diego, California, the following month. She is a sister ship to the R/V ''Thomas G. Thompson'' ( UW), NOAAS ''Ronald H. Brown'' (NOAA) and R/V ''Atlantis'' (Woods Hole), all built upon the same design. The ''Revelle'' underwent a $60 million refit between 2019 a ...

Koror, Palau
Koror City (, ;''Koror'', World Book Advanced'','' World Book, Chicago) is the largest city and the commercial center in Palau, home to about half of the country's population, located on Oreor Island. During the interwar period it served as the capital of the South Seas Mandate, a group of islands that made up the League of Nations mandated territory held by the Empire of Japan. It was subsequently the capital of Palau until it was replaced by Ngerulmud in 2006. History Koror was the administrative center of the Japanese South Sea Mandate, and thousands of Japanese lived in the city.

CentOS
CentOS (, from Community Enterprise Operating System; also known as CentOS Linux) is a Linux distribution that provides a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board. The first CentOS release in May 2004, numbered as CentOS version 2, was forked from RHEL version 2.1AS. Since version 8, CentOS officially supports the x86-64, ARM64, and POWER8 architectures, and releases up to version 6 also supported the IA-32 architecture. , AltArch releases of CentOS 7 are available for the IA-32 architecture, Power ISA, and for the ARMv7hl and AArch64 variants of the ARM architecture. CentOS 8 was released on 24 September 2019. In December 2020, Red Hat unilaterally terminated CentOS development. In response, CentOS founder Gregory Kurtzer created the R ...

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 ...

Multibeam Echosounder
A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth. Unlike other sonars and echo sounders, MBES uses beamforming to extract directional information from the returning soundwaves, producing a swath of depth soundings from a single ping. History and progression Multibeam sonar sounding systems, also known as ''swathe'' (British English) or ''swath'' (American English), originated for military applications. The Sonar Array Sounding System (SASS) was developed in the early 1960s by the US Navy, in conjunction with General Instrument to map large swaths of the ocean floor to assist the underwater navigation of its submarine force. SASS was tested aboard the USS ''Compass Island'' (AG-153). The final array system, composed of sixty-one one degree beams with a swa ...

Expendable Bathythermograph
''Expendable'' is a science fiction novel by the Canadian author James Alan Gardner, published in 1997 by HarperCollins Publishers under its various imprints.Avon Books; HarperCollins Canada; SFBC/AvoNova. Paperback edition 1997, Eos Books. It is the first book in a series involving the "League of Peoples", an assemblage of advanced species in the Milky Way galaxy. There is a "sub-series" involving just the character Festima Ramos, and sometimes the female Oar. The novel introduces many concepts in Gardner's "League of Peoples" universe, such as the Explorer Corps, Sentient Citizens, and the League itself. Backstory Through the course of the novel, Gardner provides a framework, background, and conceptual structure for his future narrative. In this back-story, humanity attains a technology of "spacetime distortion" to create an effective "star drive", thus leaving the solar system to explore and colonize planets orbiting other stars. Through this exploration and colonization eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ADCP
An acoustic Doppler current profiler (ADCP) is a hydroacoustic current meter similar to a sonar, used to measure water current velocities over a depth range using the Doppler effect of sound waves scattered back from particles within the water column. The term ADCP is a generic term for all acoustic current profilers, although the abbreviation originates from an instrument series introduced by RD Instruments in the 1980s. The working frequencies range of ADCPs range from 38 kHz to several megahertz. The device used in the air for wind speed profiling using sound is known as '' SODAR'' and works with the same underlying principles. Working principle ADCPs contain piezoelectric transducers to transmit and receive sound signals. The traveling time of sound waves gives an estimate of the distance. The frequency shift of the echo is proportional to the water velocity along the acoustic path. To measure 3D velocities, at least three beams are required. In rivers, only the 2D ...
