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

Grids of upper mantle isotropic seismic velocity structure beneath Africa were contributed by Erica Emry. Derived using new full-wave seismic tomography techniques on ambient noise and earthquake data the grids shed light on relationships between mantle flow, cratonic lithosphere and surface processes. The data set has been added to GeoMapApp (Fig. 1).
As part of an integrated study of tectonic and magmatic processes during the onset of rifting, also now available in the data portal is the active-source seismic shot data from the 2015 SEGMeNT survey on Lake Malawi (Fig. 2). Led by Shillington et al. the survey focused upon the northern Malawi (Nyasa) rift, a region of early-stage rifting in strong, cold lithosphere, and imaged sedimentary and crustal structure within and around the lake. The data set is available here.

Cascadia

Derived from Cascadia Initiative OBS data, Emily Morton and Sue Bilek contributed a new microseismicity catalogue of earthquakes detected and located offshore central Oregon for the period 2011-2015. The catalog (Fig. 3) was generated using a subspace detection technique and includes hypocentral locations and duration magnitudes. The data set is available here.

New Zealand

To better understand the forces that drive early-stage subduction, investigators Mike Gurnis, Sean Gulick, Joann Stock, Harm Van Avendonk and Rupert Sutherland conducted a 2-D active-source survey of the Puysegur segment of the Macquarie Ridge Complex (Fig. 4). The 2018 Langseth cruise, dubbed “SISIE”, collected multi-channel seismic reflection data sets which may be viewed here. This Puysegur-Fiordland boundary south of New Zealand’s South Island represents a type-example of incipient subduction.

Aleutian Arc

As part of a geophysical project to study the magmatic system beneath Okmok Volcano on the eastern Aleutian arc island of Umnak, offshore magneto-telluric (MT) time series data from the Key et al. 2015 amphibious project is now available. The offshore data was collected along a 300 km-long transect perpendicular to the subduction trench (Fig. 1). The MT stations comprised more than fifty broadband ocean-bottom electromagnetic receivers. All except one was recovered.

The data set is available here.

During the July 2018 Sikuliaq cruise SKQ201816S (chief scientists Geoff Abers and Doug Wiens) ocean-bottom seismometers were deployed in the Kodiak-Katmai region as part of the Alaska Amphibious Community Seismic Experiment (AACSE). New bathymetry data collected on that cruise has been added to the Global Multi-Resolution Topography (GMRT) synthesis which forms the base map used in GeoMapApp and in GMRT MapTool.

New Zealand

Multi-channel seismic shot field data and seismic navigation files were contributed by investigators Nathan Bangs, Shuoshuo Han, Greg Moore, Eli Silver, and Harold Tobin for the early 2018 Langseth active-source survey across New Zealand’s Hikurangi Margin. In this 3-D seismic survey, four streamer cables were towed close apart to generate the 15 km x 60 km survey outline across the trench and forearc shown in Fig. 2. The Hikurangi Margin is characterised by regularly-occurring slow-slip events (SSEs) and a main goal of the survey is to gain understanding of the factors associated with slow-slip behavior.

The seismic data sets are available here.

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).

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

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.

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 keyword, NSF award number, publications, and geographical extent.
Data Management Plan tool – generates 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 760 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 for inclusion in the bibliography – just the DOI is needed!
GeoMapApp /GMRT – version 2.7 of the GMRT base map includes newly-added swath bathymetry data from eight cruises in the Cascadia region.
Contribute Data – This updated web submission tools support PI contributions of geophysical, geochemical, and sample data. File formats include grids, tables, spreadsheets, and shapefiles. Once registered within the IEDA system, the data sets become available to the broader community immediately or may be placed on restricted hold. Additionally, PIs can choose to have a DOI assigned to each submitted data set, allowing it to become part of the formal, citable scientific record. ■

October 2014 | Status Report on the GeoPRISMS Data Portal

Status Report on the GeoPRISMS Data Portal: October 2014, Goodwillie A., and the IEDA Database Team (Lamont-Doherty Earth Observatory, Columbia University)
GeoPRISMS Newsletter, Issue No. 33, Fall 2014. Retrieved from http://geoprisms.org

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 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.

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 lists of publications can be exported to EndNote™. Submit your papers – just the DOI is needed – for inclusion in the bibliography!
GeoMapApp – Free map-based data exploration and visualization tool, updated with the release of version 3.4.1 in October 2014. Enhancements include an improved interface for plotting large tabular data sets – GMRT base map tiles that now load sequentially – a beta Save Sessions/Import Sessions function that provides limited ability to save, store and re-use an instance of a GeoMapApp session, a better capability to import multiple grids at once, and a range of other modifications and bug fixes requested by the community.
Version 2.6 of the GMRT base map includes newly-added swath bathymetry for the Cascadia, Alaska-Aleutians, and ENAM primary sites. A GeoPRISMS-focused webinar is available on the GeoMapApp 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 immediately available to the broader community or can be placed on restricted hold.
