Features

  • None

    Fixes

  • More liberal in accepting Caltech format. Header parameters were expected in certain positions, if this fails the parameters are split by space instead.
  • Changed export of ChRM directions from hamburger menu to be consistent with the default input (.CSV) file. The MAD has been removed and stratigraphic level added to the export.
  • Addressed problem in Vector Difference Sum where it was mistaken for the Vector Intensity Sum. A new line colored in red was added for the VDS.
  • Fix in core-dip for MagIC export

    Features

  • Added Vaes et al., 2023 (submitted) to reference frame list.
  • APWP Online by Vaes et al., 2023 is now available!
  • Added new parser for format UNESP (2G enterprises SQUID Long Core).
  • Added new parser for format SPINNER (MAG Instruments spinner).

    Fixes

  • Fixed bug where JR5 format would expect only a single specimen in a file.
  • Fixed CSV exporting of intensity and equal area diagrams in interpretation portal.
  • Fixed reading of Caltech format in the case of a missing specimen header field. Additional sanity checks were added for the measurements.
  • Fixed MagIC headers for the specimens table.
  • MagIC sites are now determined per unique latitude and longitude instead of per sample.
  • Updated team members' insititutions and roles.
  • Added access to Paleomagnetism.org version 1.0.0 to convert legacy .dir files when importing them to the intepretation portal. Please do not use this application for anything else.

    Features

  • Shutdown of the Paleomagnetism.org version 1.0 application is scheduled on April 1st, 2022.
  • Transferred the Oroclinal test to the version 2.0 application.
  • Updated the available Geologic Time Scale to Gradstein, F.M., Ogg, J.G., Schmitz, M.D. and Ogg, G.M., 2020. Geologic time scale 2020. Elsevier.

    Fixes

  • MagIC exporting script was fixed. The output should now be a valid MagIC file.
  • MagIC output intensities (magn_x, magn_y, magn_z, magn_volume) were fixed.

Change Summary

Fixes were made to virtual geomagnetic pole calculations. The relative VGP distribution and cutoff algorithm use an arbitrary virtual site at location (0, 0). For the relative VGP distribution this does not matter. However, it means that for correct interpretation, all specimens in a collection should come from geographically adjacent areas.

    Features

  • Added VGP longitude, latitude to mean downloads CSV and JSON. This VGP is based on the mean of individual poles. It is not the VGP of the mean of directions which may differ slightly.
  • Added option to show tick labels to Zijderveld plot.
  • Added MAD angle in statistics portal directional tab CSV exporting. The MAD angle is only carried over from imported .col files since 2.2.1.
  • Added option in settings tab to overlay individual samples in the collection mean tab.
  • Added option in settings tab to set each mean collection to a random color.
  • Added format for University of Helsinki (using block orientation).

    Fixes

  • Fixed tooltip of site mean VGP in geography portal. The tooltip showed the projected equal area inclination instead of true inclination.
  • Added disclaimer under the VGP distribution in the directions tab in the statistics portal to emphasize it is a relative distribution assuming a single site.
  • Fixed bug in great circle PCA in geographic and tectonic coordinates where the pole to the plane was presented antipodal. The convention is that the pole is presented as negative (this has no effect on results).
  • Swapped line styles for lower (solid) and upper (dashed) GC in hemisphere plot.
  • Changed ordering of directions, mean and ellipse. Mean and ellipse should be on top in equal area plots.
  • Fixed multiple problems with the Geological Survey of Finland format. Geographic coordinates were interpreted as specimen coordinates and some leading numerals were dropped reading the file. Data interpreted with this format before version 2.3.0 are therefore incorrect.

Change Summary

Some bugs were fixed reading various input formats.

    Features

  • Demagnetization type can not be applied to all loaded specimens by clicking the thermal or alternating field demagnetization buttons while control is held down.
  • Added input format for the Geophysical Survey of Finland (GTK).
  • Added Cenieh regular importing.

    Fixes

  • Fixed graph scaling for very small intensities.
  • Fixed bug reading BGN2G input format (PGL Beijing, University of Barcelona) where some lines were dropped.

Change Summary

New features were added to Paleomagnetism.org!

    Features

  • Added option when saving a new collection from data to normalise directions (normal, reversed, flip).
  • The map in the geography portal now supports loading and displaying of simple literature data distributions for plotting (confidence parachutes).
  • Added University of Rennes input format to the interpretation portal.
  • Added University of Montpellier input format to the interpretation portal.
  • Confidence ellipes in the statistics portal are now not-flipped to antipodal positions by default. You can re-enable this setting in the settings tab.

    Fixes

  • Fixed UTF-8 exporting of combined PDF graphics.
  • Fixed issue in BCN2G routine with broken input (see #72).
  • Fixed field headers in the MagIC exporting portal.

Change Summary

A bug in the Utrecht format where the intensity was not corrected for the sample volume was fixed. This error does not affect directional statistics. Specimens with this problem will be marked but may at a later stage be corrected.

    Features

  • Added information page that decribes how Paleomagnetism.org 2.0 implements the FAIR principles.

    Fixes

  • When reading Utrecht format files the sample volume was ignored in the intensity calculation. It is now calculated correctly for newly loaded specimens, and correctly displayed in the interpretation portal for old specimens. Specimens in the data library with input format UTRECHT and below version 2.0.1 are in Am^2 and should be divided by the sample volume and brought to µA/m.
  • Fixed regression introduced by commit 94fa96dbda1742b0104e79feae548fed43dc8496 where the last step in Utrecht format for every specimen was not read.
  • Loading files from the Paleomagnetism.org 1.0.0 format now correctly sets the sample volume.
  • The y-axis of the intensity diagram was changed from µA/m to fraction when normalization is requested.
  • Fixed non-ASCII characters in exporting of single charts in PDF. Unicode support is not available for combined charts. We recommend exporting combined charts as SVG.
  • Intensity diagram is redrawn when option normalize intensities in the settings tab is changed.

Change Summary

Some new features were added for user convenience. Minor bugs were fixed.

    Features

  • Added window to add some metadata to collections in the statistics portal. This can be used when exporting .pub files for sharing for literature data that cannot be submitted to the data library.

  • The PalPole description on the miscellaneous portal has been updated.
  • A warning is now shown when the application is run in to beta mode.
  • Map width in the geography portal has been reduced and bounds were removed (#51, #52).
  • Fixed GPlates rotation files for plate ID "0" which is the same as "000" (#54)
  • Fixed accidental swap of latitude, longitude in publication preview map.
  • Fixed CTMD test not working for reversed directions.
  • Added Remasoft (RS3) file format.
  • Data library author information is now taken from DOI by default.
  • Added age and generated country based on lat, lng to data library.
  • Prevent linking to statistics/geography portal when no interpreted components are available.

Change Summary

The release of Paleomagnetism 2.0.0 exists in parallel with the old application. The old version may have some additional features in the statistics portal that were removed in this version. This version of Paleomagnetism.org focuses on raw demagnetization data and its provenance, and may therefore be more limited in what it allows.

  • Added support for reading MagIC files in the interpretation portal.
  • Implemented keyboard shortcuts for A95, a95 confidence and switching between coordinate reference frames.
  • Support for extended metadata (e.g. specimen location, lithology) per specimen.
  • Map & APWP module from the statistics portal were moved to the geography portal.
  • Magnetostratigraphy tool was moved to the geography section.
  • The magnetostratigraphic column is now rendered automatically from the polarity of the inclination.
  • Added option to upload custom plate rotations from a GPlates .rot file.
  • Added option to add APWP from a csv file.
  • Core and bedding parameters can now be changed within the application.
