Marine science data collected using the U.S. academic research fleet support a diverse array of investigations across the ocean sciences, targeting important questions ranging from the impacts of global change on ocean chemistry and ecosystems, to the structure and dynamics of ocean circulation, to the nature of volcanic and earthquake processes at...

The International Geo Sample Number (IGSN) is a unique identifier for samples and specimens collected from our natural environment. It was developed by the System for Earth Sample Registration SESAR to overcome the problem of ambiguous naming of samples that has limited the ability to share, link, and integrate data for samples across Geoscience da...

There is a general need in the ocean science community for a widely accepted standards-based ``cruise-level'' metadata profile that describes the basic elements of a seagoing expedition (e.g. cruise identifier, vessel name, operating institution, dates/ports, navigation track, survey targets, science party, funding sources, scientific instruments,...

The goal of the Rolling Deck to Repository (R2R; rvdata.us) program is to develop and implement a fleet-wide information management system to preserve and provide access to routine underway data collected by U.S. academic research vessels. One of the program's primary challenges is to develop a workflow for routinely gathering data from a fleet wit...

A new era of ocean exploration brings with it a challenge to take the next step, making the discoveries available to a wider audience. Mapmakers, artists and collectors were on board the voyages of discovery of the eighteenth century, and the resulting atlases and exhibits captured the public's imagination, laid the foundation for scientific inquir...

NSF-supported oceanographic research expeditions support diverse scientific investigations across all disciplines of ocean sciences, targeting important questions ranging from the impacts of global change on ocean chemistry and ecosystems, to the structure and dynamics of ocean circulation and the nature of volcanic and earthquake processes at the...

In recent years data sharing has become much more common in the Marine Science Community, and data are frequently being re-used without the direct involvement of the original data collector. Whereas ``in the old days'' you used to go to sea, collect your own data, work it up, publish it and then exchange reprints, it is now common to combine data f...

The NSF-funded Rolling Deck to Repository (R2R) project envisions the academic research fleet as an integrated global observing system, with routine ``underway'' sensor data flowing directly from research vessels to a central shore-side repository. It is a complex endeavor involving many stakeholders - technicians at sea, data managers on shore, sh...

"I just want a picture of the ocean floor in this area" is expressed all too often by researchers, educators, and students in the marine geosciences. As more sophisticated systems are developed to handle data collection and processing, the demand for quality data, and standardized products continues to grow. Data management is an invisible bridge b...

Data gathered during NSF-supported scientific research cruises represent an important component of the overall oceanographic data collection. The Rolling Deck to Repository (R2R) pilot project aims to improve access to basic shipboard data and ultimately reduce the work required to provide that access. Improved access will be achieved through ident...

Data are now being re-used by a far wider circle of researchers and students than ever before, across a broader range of disciplines. Before, during, and after a field program, the exchange and merging of information is a dynamic, iterative and sometimes anonymous process that may occur years, or decades, after the data were initially acquired. Col...

The Enduring Resources for Earth Science Education (ERESE) Project bridges the gap between earth science research and science education by providing a forum for electronic collaboration between practicing scientists and classroom teachers. By combining the resources of Scripps Institution of Oceanography (SIO) and the expertise of educators, ERESE...

As the oceanographic community ventures into a new era of integrated observatories, it may be helpful to look back on the era of "mobile observatories" to see what Cyberinfrastructure lessons might be learned. For example, SIO has been operating research vessels for 104 years, supporting a wide range of disciplines: marine geology and geophysics, p...

The Scripps Institution of Oceanography (SIO) and the Woods Hole Oceanographic Institution (WHOI) have joined forces with the San Diego Supercomputer Center to build a testbed for multi-institutional archiving of shipboard and deep submergence vehicle data. Support has been provided by the Digital Archiving and Preservation program funded by NSF/CI...

The next generation all-digital Site Survey Data Bank (SSDB) became operational on August 15, 2005 as an online resource for Integrated Ocean Drilling Program (IODP) proponents, reviewers, panels and operations, worldwide. There are currently 123 active proposals for drilling at sites distributed across the globe, involving nearly 1000 proponents f...

To bridge the gap between Earth science teachers, librarians, scientists and data archive managers, we have started the ERESE project that will create, archive and make available "Enduring Resources in Earth Science Education" through information technology (IT) portals. In the first phase of this National Science Digital Library (NSDL) project, we...

Strategies for interoperability have been an underlying theme in the development of the SIOExplorer Digital Library. The project was launched three years ago to stabilize data from 700 cruises by the Scripps Institution of Oceanography (SIO), scattered across distributed laboratories and on various media, mostly off-line, including paper and at-ris...

What began two years ago as an effort to stabilize the Scripps Institution of Oceanography (SIO) data archives from more than 700 cruises going back 50 years, has now become the operational fully-searchable "SIOExplorer" digital library, complete with thousands of historic photographs, images, maps, full text documents, binary data files, and D vis...

The launching of an oceanographic expedition has its own brand of excitement, with the sound of the main engines firing up, and the lifting of the gangway in a foreign port, as the team of scientists and crew sets out for a month at sea with only the resources they have aboard. Although this adventure is broadly appealing, very few have the privile...

Can we make a research tool also work for student discovery experiences? Earth Science digital libraries primarily exist on two separate planes: interfaces for accessing first order data as collected by scientists (i.e. CruiseViewer, http://nsdl.sdsc.edu ), and libraries of indexed educational resources developed for use by teachers in the classroo...

SIOExplorer (http://SIOExplorer.ucsd.edu) is now in operation as a web portal to the discoveries of the Scripps Institution of Oceanography. Data, images and documents from 822 SIO cruises are being placed online, integrated with a growing seamount catalog, global databases, and historic archives. More than just a web site or online archive, SIOExp...

The SIOExplorer project began with a desire to organize the data archives of the Scripps Institution of Oceanography, which include the observations from 822 cruises over 50 years. Most of the data volume comes from 244 multibeam seafloor swath mapping cruises since 1982. Rather than just create an online archive or a website, the decision was mad...

Data, documents and images from 795 expeditions by the Scripps Institution of Oceanography (SIO) since 1903 are becoming web-accessible for both education and research through the new SIOExplorer project (http://SIOExplorer.ucsd.edu), which is a collection in the overall NSF-funded National Science Digital Library (www.nsdl.org). The collaborative...

We are introducing "CruiseViewer" as a prototype graphical interface for the SIOExplorer digital library project, part of the overall NSF National Science Digital Library (NSDL) effort. When complete, CruiseViewer will provide access to nearly 800 cruises, as well as 100 years of documents and images from the archives of the Scripps Institution of...

The diversity of the data held by the Geological Data Center at SIO is a tribute to the evolution of oceanography, from echo sounding rolls and hand-drawn charts to modern multibeam bathymetry. However, the changes in sensor technology and organizational approaches since 1903 present real challenges to the archivist, as we struggle to migrate the h...

The newly launched SIOExplorer: Digital Library Project is a joint effort between oceanographers, librarians and computer scientists to integrate access to data, imagery and publications, using modern database technologies and metadata standards

The package provides sonar operators with a flexible set of screen-based tools for viewing and analyzing swath-sonar data in real time. Features and capabilities of the package are discussed. Implementation and applications are outlined. Survey d...

SeaMapper is a new software package providing GUI-based tools for the post-processing and display of swath mapping sonar data. SeaMapper is divided into four major components; project management, data processing, data browsing, and map display. The project management component handles the many types of information required to produce multibeam maps...

SeaSurvey is a new software package providing screen-based tools for viewing and analyzing swath sonar data in real-time. A variety of map and 3D perspective views of bathymetry and sidescan data are generated as the sonar data are collected. The underlying data i/o is modular and supports many sonar data formats. The displays can be interactively...

Preliminary results are presented from an expedition to the ultra-fast spreading segment on the East Pacific Rise. The combined multibeam and sidescan sonar worked extremely well, and provided the authors with surprising discoveries of abundant off-axis volcanism. Individuals from several institutions have contributed to a collection of public doma...

ALVIN investigations have defined the fine-scale structural and volcanic patterns produced by active rift and spreading center propagation and failure near 95.5 W on the Galapagos spreading center. Behind the initial lithospheric rifting, which is propagating nearly due west at about 50 km m.y.–1, a triangular block of preexisting lithosphere is be...

High-resolution images covering large areas of the seafloor reveal numerous discontinuities along the mid-ocean ridge. These discontinuities occur at a range of scales (10−1,000 km) and define a fundamental segmentation of seafloor spreading centres. Some are transient; others persist for millions of years, migrating along the mid-ocean ridge and d...

Nontransform ridge axis discontinuities, such as propagating rifts, overlapping spreading centers (OSCs) and saddle points, occur frequently along the mid-ocean ridge system. We used Sea Beam and deep-tow to study an example of a relatively large nontransform offset near 20o40'S on the East Pacific Rise (EPR). The two spreading center tips are 15 k...

We have tested and corroborated the propagating rift hypothesis with high-resolution Sea Beam and Deep-Tow data collected over the Galapagos 95.5°W propagating rift system. The propagating rift is continuously breaking through the Cocos plate at a velocity of about 50 km/m.y. with an azimuth of about 273°, away from the Galapagos hotspot. This proc...

A near-bottom magnetic survey was conducted over the Brunhes/Matuyama reversal boundary near the East Pacific Rise crest at 21°N. Magnetic measurements were made on a level plane approximately 200 m above the sea floor using the Marine Physical Laboratory's deep-tow vehicle, with precise transponder navigation. Track density was high both parallel...

The Tamayo transform fault occurs at the north end of the East Pacific Rise where it enters the Gulf of California. The two deep-tow surveys reported here show that the transform fault zone changes significantly as a function of distance from the spreading center intersections. At site 1, near the intersection, one side of the fault is young and th...

Our long range goals have been to achieve an understanding of crustal accretion along the Southern Mid-Atlantic Ridge. We address this problem with a combined analysis of bathymetry and sea surface magnetic data from two extensive Sea Beam surveys of the ridge between 25 deg-28 deg S and 30 deg-38 deg S. We are particularly interested in how crusta...

The Scripps Institution of Oceanography, the UCSD Libraries and the San Diego Supercomputing Center have joined forces to establish a digital library for accessing a wide range of multibeam and marine geophysical data, to a community that ranges from the MGG researcher to K-12 outreach clients.
