The GeoPRISMS data portal was established in 2011 to provide convenient access to data and information for each primary site as well as to other relevant data resources. Since the last newsletter report, highlighted below are recent contributions of data sets and field program information of interest to the GeoPRISMS community. Many of the data sets described are also available in GeoMapApp under the Focus Site and DataLayers menus.

East African Rift System

A new aeromagnetic total magnetic intensity data set collected in 2013 for the Karonga area of northern Malawi Rift was contributed by investigators Estella Atekwana, Jalf Salima, and Leonard Kalindekafe. In addition, 2-D electrical resistivity tomography profiles acquired in the same area during 2015 were provided by Estella Atekwana, Daniel Lao-Davila, and Folarin Kolawole. The data sets were used by the researchers in their studies of the early stages of continental extension and active deformation of the Malawi Rift North Basin hinge zone.

Cascadia

As part of a project investigating thermal structure, hydration and dehydration of the Juan de Fuca plate, stacked receiver function data files and station orientation estimates for Cascadia Ocean Bottom Seismometer stations were received from investigators Helen Janiszewski, Jim Gaherty, and Geoff Abers. The data set is referenced in Janiszewski and Abers, 2015.

Outreach

Analytical EarthChem geochemistry data tables were updated for all GeoPRISMS and MARGINS focus sites in GeoMapApp. The USGS-ANSS earthquake catalogues were also updated to include the most current events. A new United States mainland PACES gravity model of free-air and complete Bouguer anomalies covers the Cascadia and ENAM primary sites was added, along with updated geology-lithology maps of the western US.

ENAM

An updated USGS bathymetric compilation of the ENAM margin was added to GeoMapApp. Based upon 32 multibeam swath mapping surveys collected between 1990-2015, the new compilation covers 725,000 square kilometers of seafloor. Also added for this margin was basic field program information for the MGL1514 active-source magneto-telluric/electromagnetic (MT/EM) experiment designed to map the presence and extent of freshwater in ENAM shelf sediments, an effort led by PIs Kerry Key and Rob Evans.

Gulf of California

As part of the their studies on the Neogene rifting history of the Gulf of California MARGINS focus site, PIs David Kimbrough, Marty Grove and Peter Lonsdale contributed Zircon U-Pb geochronology data for submerged and terrestrial continental crust rock samples (Fig. 1).

Cascadia

A range of seismic velocity models of the Western US has been added to GeoMapApp, under the Focus Sites menu. Based upon tomographic techniques, the models include the 2014 Gao and Shen Cascadia 3-D shear-wave velocity model, the Porritt et al. (2011) PNW10-S Pacific Northwest dVs model and the Gilbert (2012) crustal thickness model derived from receiver function analysis of EarthScope USArray data. Also incorporated were the North American DNA-13 joint inversion model of Porritt et al. (2013) and the SAWum_NA2 Vs upper mantle velocity model of Yuen and Romanowicz (2011). Complementing these seismic tomography models is the McCrory et al. 2006 model of depth to the subducting Juan De Fuca slab beneath the Cascadia margin (Fig. 2).

GMRT base map

The Global Multi-Resolution Topography (GMRT)  synthesis is the base map used in GeoMapApp, in the GMRT MapTool, and in other IEDA tools. The GMRT now includes processed multibeam swath bathymetry data from more than 270 cruises within GeoPRISMS primary sites.

The GeoPRISMS data portal was established in 2011 to provide convenient access to data and information for each primary site as well as to other relevant data resources. Since the last newsletter report, highlighted below are recent contributions of data sets and field program information of interest to the GeoPRISMS community. Most of the data sets described are also available in GeoMapApp under the Focus Site menu.

ENAM

Bathymetry and backscatter data collected as part of a US Extended Continental Shelf survey of the central ENAM margin was contributed by James Gardner and Brian Calder. The new data, shown in figure 1, was generated during Langseth cruise MGL1512 in 2015 and marks the completion of bathymetric data surveying along the entire length of the margin.

Also added to the portal for the ENAM area was field program information for the Mid-Atlantic Geophysical Integrative Collaboration (“MAGIC”) seismometer network. Using data from the array, project PIs Maureen Long, Maggie Benoit, Eric Kirby, and Scott King are studying crustal and upper mantle structure in the area of the Appalachian Mountains. The seismic station locations were also added to GeoMapApp, under the Focus Sites menu.

New Zealand

PIs Robert Harris, Anne Trehu, and Andy Fisher contributed multi-channel seismic shot and processed heat flow data sets collected across the Hikurangi subduction margin during the 2015 “STINGS” cruise. That Revelle expedition surveyed both the northern part of the margin – a creep-dominated subduction interface with shallow slow slip earthquakes (SSEs) – and a southern area with deep SSEs.

Cascadia, Alaska, and Hikurangi margins

Drill core and sediment sample analysis spanning each GeoPRISMS SCD primary focus site is being used by PI Neal Blair to assess the role of multicycle carbon at subduction margins. Links to the analytical geochemical data sets and to related publications are provided in the Portal. DOIs were assigned to the data sets, allowing them to be a formally-cited part of the scientific record.

Aleutians

During summer 2015, PIs Ninfa Bennington and Kerry Key led a shoreline-crossing field program in the vicinity of Okmok Island. MT instruments were deployed in onshore and offshore locations as part of an experiment to study the magmatic system beneath the volcano (Fig. 2). A suite of broadband seismometers installed on the island will be picked up later this year. The MT and seismic instrument stations were also added to GeoMapApp.

GMRT base map

The Global Multi-Resolution Topography (GMRT) synthesis – The base map used in GeoMapApp, in the GMRT MapTool, and other IEDA tools now includes processed multibeam swath bathymetry data from more than 270 cruises within GeoPRISMS primary sites.

Since the last newsletter report, highlighted below are recent contributions of data sets and field program information of interest to the GeoPRISMS community. Most of the data sets described are also available in GeoMapApp under the Focus Site menu.

During summer 2015, Data Portal staff helped the GeoPRISMS Office expand the on-line, searchable GeoPRISMS bibliography which now contains more than 1,120 citations and includes links to papers, data sets, and field expedition information.

New Zealand

Basic field expedition information was added to the Portal for two Revelle cruises to the Hikurangi subduction margin: The “STINGS” expedition led by PIs Robert Harris, Anne Trehu, Stuart Henrys, and Andy Fisher that collected heat flow and seismic data to help understand the region’s thermal structure (RR1508); and, the “HOBITSS” cruise in which sea-bottom pressure gauge, seismometer, and electromagnetic instruments were recovered after a year-long deployment (co-chief scientists were Laura Wallace, Susan Schwartz, Anne Sheehan, and Spahr Webb, RR1509) (fig.1).

Cascadia

High-resolution airborne LiDAR land elevation data sets with a horizontal grid spacing of 1/9th arc second (~3m) has been added to GeoMapApp for the Cascadia margin volcanoes Mount Rainier, Mount St. Helens, Mount Hood, Three Sisters, Mount Bachelor, Crater Lake, and Mount Shasta. As shown in Fig.2, the LiDAR data provides unprecedented map detail for these volcanic regions. For the marine Cascadia component, Paul Johnson contributed multibeam swath bathymetry data from 2005 cruise TN177 which surveyed the shelf break and canyon area offshore Grays Harbor, WA.

ENAM

Continuing the USGS Extended Continental Shelf survey of the ENAM margin, Deb Hutchinson, Nate Miller, and Warren Wood conducted a 2-D multi-channel seismic reflection survey aboard R/V Langseth, MGL1506, in April 2015. That was followed by MGL1510, a community-based, open access 3-D seismic survey of the New Jersey margin in which PIs Greg Mountain, Craig Fulthorpe, Mladen Nedimovic, and Jamie Austin mapped the stratigraphic detail of shallow depositional systems as part of their study on facies and sea-level change. Field information for both expeditions is available through the Portal.

Experimental

The Portal now provides links to Kyle Straub’s GeoPRISMS sediment tank modelling experiments related to the stratigraphic architecture and geomorphological dynamics of passive margins.

GeoMapApp –  version 3.6.0 of GeoMapApp was released. The new DataLayers menu consolidates the wide range of built-in global, regional, and local geoscience data sets that were originally listed under the Basemaps and Datasets menus in earlier versions of GeoMapApp. The consolidation allows the DataLayers menu to be structured more intuitively and managed more efficiently. The many built-in data sets are now arranged in the following categories that were chosen to reflect big-picture geoscience fields and themes.
For example, the new Geophysics menu includes data sets ranging from lithospheric plate deformation, earthquake catalogues, gravity and magnetics anomalies, to heat flow data; and, the Geology category includes geological maps and interpretations, volcano catalogues, and seafloor characteristics. LiDAR data shown in Fig. 2 was also added to GeoMapApp.
The Session Manager (Save Session) has been enhanced and offers a basic ability to store, share, and re-use an instance of a GeoMapApp session. The captured information is stored as a small file that can be shared with colleagues and students. A saved session could be shared with a class to allow every student to open GeoMapApp at exactly the same starting point with the same data layers loaded and the same area displayed. When using GeoMapApp to generate a figure for publication, storing the session could be useful for its later reuse.

Aleutian Arc

Bathymetric grids, generated at 50m horizontal resolution from processed EM300 multibeam swath data, were contributed by Gene Yogodzinski and Scott White from data acquired in 2005 during a geophysical and geochemical survey of the Aleutian back-arc (Fig. 1). In the last newsletter, we reported on Aleutian arc geochemistry and mineralogical data from twenty published articles being included in the EarthChem-PetDB database. A new batch of analytical data from a further 31 papers published between 1971 and 2010 has since been included. The data sets from this new compilation can be accessed via PetDB  (Search by “Feature Name > Volcanic Arc > Aleutian”) or via the EarthChem Portal (use the map-based “Set Location” to define a polygon around your area of interest). If you have suggestions for additional data sets or comments about the current data please contact the PetDB team at info@petdb.org.

EARS

A preliminary East African Rift System geodetic velocity field compiled from continuous and survey mode GPS networks was contributed by Bob King, Michael Floyd, Rob Reilinger, and Becky Bendick. Derived from field data acquired between 1994 and 2013, the data set is part of a wider Africa-Arabia-Eurasia velocity field calculation and is available here.

Cascadia

Details on Cascadia Initiative Year 4 ocean bottom seismometer deployment and recovery operations are available, along with MT instrument locations for the on-going land-based iMUSH program. Station information for Dave Chadwell’s seafloor geodesy transponder array was also added. From their 2013 cruise AT26-04, Paul Johnson, Evan Solomon, and Rob Harris provided long probe and thermal blanket processed heat flow data. For the Juan de Fuca Endeavour segment, PIs William Wilcock, Emilie Hooft Toomey, and Doug Toomey contributed an earthquake microseismicity catalog for years 2003-2006 as well as a seismic velocity model for the area.

ENAM

The main offshore component of the multi-PI, shoreline-crossing ENAM Community Seismic Experiment took place in Fall 2014 with an R/V Langseth seismic survey. Shots were recorded by Langseth streamers and ocean floor OBS instruments as well as by broadband and short-period seismometers on land. Multi-channel seismic data and field information from the experiment, including land seismometer and OBS deployments, were added to the portal (Fig. 2). Information and data for the preceding Langseth cruise – a USGS Extended Continental Shelf survey, led by Deb Hutchinson and Nate Miller – were also contributed.

Since the last newsletter report, highlighted below are recent contributions of data sets and field program information of interest to the GeoPRISMS community.

Aleutian Arc

The EarthChem-PetDB database, now in release version 2.8.1, is part of the NSF-funded IEDA data facility and provides a global synthesis of chemical, isotopic, and mineralogical data for rocks, minerals, and melt inclusions. Guidance from a group of Aleutian arc investigators has helped identify high-profile geochemical analytical data sets for the Aleutian Primary Site to aid the GeoPRISMS community with data synthesis and interpretation. Geochemical data sets and sample information from more than twenty articles published between 1971 and 2010 have so far been added to the database by the EarthChem team (Fig. 1) and can be accessed via PetDB (Search by “Feature Name >Volcanic Arc > Aleutian”) or via the EarthChem Portal  (use the map-based ‘Set Location’ to define a polygon around your area of interest).
A second upload of Aleutian arc data will follow in early 2015, bringing the compilation of geochemical and mineralogical data sets to a total of nearly sixty publications. If you have suggestions for additional data sets or comments about the current data please contact the PetDB team at info <at> petdb.org.

Cascadia

High-resolution processed multibeam bathymetry grid surveys covering part of the continental shelf and slope offshore Washington state were contributed by GeoPRISMS investigator Paul Johnson. The swath data sets were collected during the seafloor mapping phases of cruises TN177 (2005) and TN207 (2007) cruises. Information on Cascadia Initiative Year 4 ocean bottom seismometer operations is also available. In addition, following a successful permitting process and an intensive installation program during the summer of 2014, station information for the Imaging Magma Under St. Helens (iMUSH) program has been added to the GeoPRISMS data portal and is accessible in GeoMapApp from the Focus Site menu (Fig. 2).

ENAM

Multichannel seismic field data files, in SEG-Y format, were added for the 1974 International Phase of Ocean Drilling (IPOD) Site Survey line from Cape Hatteras to the Mid-Atlantic Ridge. The data set was collected on cruise GS1974 that was led by John Grow and Rudi Markl. Also for the ENAM region, a Calais et al. (2006) geodetic vertical velocity data set for North America was added to GeoMapApp in both gridded and tabular format. Details of the recently-completed ENAM Community Seismic Experiment aboard R/V Langseth will soon be added to the data portal.

The GeoPRISMS Data Portal was established in 2011 to provide convenient access to data and information for each primary site as well as other data resources. Since the last newsletter report, the database group participated in the EarthCube workshop for the DEFORM/Compress communities, worked with Jim Gill on a data rescue effort to compile decades of geochemical analyses for the Izu arc, released the version 2.7.0 of PetDB which includes enhanced data access functionality, and expanded the on-line GeoPRISMS bibliography that now offers 730 citations, many linked to data. Highlighted below are other recent contributions of data sets and field program information of interest to the GeoPRISMS community.

Cascadia

Open-access cleaned CTD data from AT26-04, the summer 2013 Atlantis heat flux cruise run by Paul Johnson, Evan Solomon and Rob Harris, was added to the portal. For Cascadia Initiative Year 3 operations, ocean bottom seismometer deployment & recovery information, and other field details are now available. Instrument tables for Years 1, 2 and 3 of OBS operations have also been updated in GeoMapApp, where they are listed under the Focus Site menu. Using more than a thousand stations including EarthScope USArray TA instruments, Haiying Gao and Yang Shen generated a shear wave velocity ambient noise tomographic model of Cascadia, now linked from the portal (Fig. 1).

ENAM

Covering the magma-starved West Iberia-Galicia passive rifted margin, site of last year’s Langseth 3-D seismic experiment (cruise MGL1307 led by Dale Sawyer, Donna Shillington, Tim Reston, Cesar Ranero and Juli Morgan), a new 500 m EMODnet bathymetric grid compilation of European data was added to GeoMapApp (Fig. 2a). The grid is available under the Base Maps > Bathymetry > North Atlantic menu.

Central America

Spectacularly-detailed gridded data sets of bathymetry and acoustic backscatter were contributed by investigators Jared Kluesner, Nathan Bangs, Cesar Ranero, Kirk McIntosh and Eli Silver who, as part of the CRISP imaging project (Langseth cruise MGL1106), acquired high-quality 3-D seismic data across the Costa Rica shelf and slope in 2011. Novel range-angle data processing techniques that took advantage of a close line spacing and overlapping swaths allowed the EM122 multibeam sonar data to be gridded at an unprecedented 10 m interval for bathymetry and 5 m for backscatter (Fig. 2b). The grids have been added to GeoMapApp, under the Focus Site > Central America menu, and are available for download from the Langseth cruise web page.

Gulf of California

As part of a collaborative data curation effort with the Hawaii Mapping Research Group towed IMI30 bathymetry and sidescan data (grids, images and underlying data files) are now available through the portal for Dan Lizarralde’s 2009 Atlantis cruise AT15-54 to the Guaymas Basin area, part of the MARGINS Gulf of California focus site.

GeoPRISMS Data Portal Tools and Resources

Search For Data – The customised GeoPRISMS search tool provides a quick way to find GeoPRISMS data using parameters such as key word, NSF award number, publications, and geographical extent.
Data Management Plan tool – generate a data management plan for your NSF proposal. The on-line form can be quickly filled in, printed in PDF format, and attached to a proposal. PIs can use an old plan as a template to create a new plan. We also have developed a tool to help PIs show compliance with NSF data policies.
GeoPRISMS Bibliography – with more than 700 citations, many tied to data sets, the references can be searched by primary site, paper title, author, year, and journal. The lists of publications can be exported to EndNote™. Submit your papers – just the DOI is needed – for inclusion in the bibliography!
GeoMapApp – a free map-based data exploration and visualization tool was updated with the release of version 3.3.9 in February 2014. Enhancements include default caching of the multibeam portal, improved handling of imported and exported Excel™ spreadsheets, an updated Earthquake Focal Mechanisms portal that now contains data up to August 2013, a Projection menu that allows users to switch map projection without leaving the interface, an expanded FAQ web page, and a modified grid manipulation window. Version 2.5 of the GMRT base map includes swath bathymetry for Cascadia and other areas. A GeoPRISMS-focused webinar is available on the GeoMapApp Youtube channel and shows how to generate custom maps, how to explore built-in data sets of interest to the GeoPRISMS community, and how to import your own data.
Contribute Data – this updated web tool provides a simple way to submit grid files, tabular data sets, spreadsheets, and shapefiles. Once added to the GeoPRISMS database, these data sets become available to the broader community immediately or can be placed on restricted hold.

October 2013 | Status Report on the GeoPRISMS Data Portal

The GeoPRISMS data portal was established in 2011 to provide convenient access to data and information for each primary site as well as to useful data resources. Since the last newsletter report, the database group presented at the spring GeoPRISMS Steering and Oversight Committee meeting; had discussions with PIs about data products to be generated with their NSF awards; and, expanded the on-line GeoPRISMS bibliography to offer more than 700 citations, many linked to data. In GeoMapApp, EarthScope USArray station tables and EarthChem geochemistry analytical data sets were updated. And, as part of a summer series of in-depth GeoMapApp webinars recorded and placed on Youtube, one webinar showcased data sets and functionality relevant to the GeoPRISMS community. Highlighted below are some recent contributions of field program information and data sets of interest to the GeoPRISMS community.

Cascadia

Cascadia Initiative Year 3 OBS operations saw six OBS cruises take place between spring and autumn: three for recoveries followed by three for deployments. As in previous field seasons, the OBSs included shallow-water instruments designed to withstand fishing net trawls. Year 3 OBSs are expected to be picked up next year. Field program information and links to data for each Cascadia Initiative cruise are available via the GeoPRISMS data portal. Map-based OBS station information can be found in the GeoMapApp Focus Site menu as shown below.
There was continued focus on a bathymetric compilation for Cascadia. Version 2.5 of the Global Multi-Resolution Topography (GMRT) synthesis is used as the base map in GeoMapApp and incorporates cleaned sonar data from an additional 5 Cascadia cruises, including AT26-04, the summer 2013 Atlantis heat flux cruise run by Paul Johnson, Evan Solomon and Rob Harris.
Basic project outlines were also added to the portal for three other Cascadia projects: the summer 2012 Washington and Oregon onshore seismometer deployments of Anne Trehu and Geoff Abers in which airguns fired during R/V Langseth’s offshore seismic work (cruises MGL1211 and MGL1212) were recorded; and, lead PI Ken Creager’s inter-disciplinary, multi-institution iMUSH (Imaging Magma Under St. Helens) program.

ENAM

Conjugate to the Newfoundland margin, the West Iberia-Galicia margin was the site of a large-scale 3-D seismic survey during summer 2013.
A two-ship experiment led by Dale Sawyer, Donna Shillington, Tim Reston, Cesar Ranero, Milena Marjanovic and Juli Morgan, cruise MGL1307 collected high-quality multi-channel and OBS data to study this magma-starved passive rifted margin (Fig. 2).
