Contaminated data?

It’s been a while since the last blog post. We’ve been busy getting v3.0 out there and fixing anything that’s been cropping up, and many have now upgraded, or plan to upgrade in the near future.

One of the small but important changes in v3.0 was the addition of an occurrence type for “Transported” specimens, being those that are reworked environmentally but not stratigraphically. As well as this, we combined the “Caved” attribute into the same occurrence type, making them mutually exclusive, and thereby forming a hierarchy of “levels of displacement”, which begins with “In-situ” and ends with “Caved”, as illustrated on the new Picklist:

Since this introduction, we’ve had some feedback on whether we should also add a further level, of “Contaminated” occurrences. This would sit below Caved in the hierarchy. These can be specimens from modern contaminants, the lab, or drilling mud itself, none of which implicate caving of the borehole, but would be useful to be able to exclude from certain displays and operations.

We could add this new type as a further option in the v3.0 list. It would not require any changes to existing v3.0 databases, but an application update would be required for v3.0 (and v2.1) to be able to handle any data set which uses the new attribute.

Any comments on this proposal, positive or negative, would be welcome.

Thank you all for attending the webinar series so far. There will be a break next week, so the repeat of session 4 on a Tuesday will take place on the 2nd May 16.30 BST, registration link here. Session 4 will cover chart basics, how the templates work together, how to construct, use and edit templates to create charts.

Session 5 will extend the charts session and discuss maps, creating map blocks and layer templates. The first webinar of session 5 will be on Thursday 4th May at 10.00 BST, registration link here.

Webinar dates for sessions 2, 3 & 4

Contact me if you would like to access a recording or slides from the previous sessions.

Session 3 – Recording data – Taxa – Events – will be repeated on Tuesday 18th at 16:30 BST, registration link here.

Session 4 – Chart panels, layers, blocks and templates will be on Thursday 20th April at 10.0 BST, link here

There will be NO sessions in the week beginning the 24 April, we will resume the following week (w/c May 1st)

StrataBugs webinar dates

Thanks to everyone for attending the first session, good to get the ball rolling! Try to install v3.0 before next week’s session, where we will diving into the concepts and practicalities of recording some data. If you missed the first session, or want to recap, you can join the repeat on Tuesday, otherwise get in touch if you need help installing. In session 2 there should be more time for questions and you can try some of the practical tasks on your own database.

Dates and links for future StrataBugs webinars:

Session 1 repeat: 16.30 BST Tuesday 4th. Registration link:–HMTw,bDxBSYuBMkOULOmn1_7vZw,ciriNPoqGEqGL7TaHFOs6g,d0t-44J3cUSiPWKqRmEQMw,JWFUcqZZHEapXTRAG5aoOA,Wlr5ipMj4U6rxeKISLEh4A?mode=read&tenantId=8e148ee9-f5dd-42f8-87ec-612bfbe1cc4f

Session 2 10.00 BST Thursday 6th April. Registration link:–HMTw,bDxBSYuBMkOULOmn1_7vZw,ciriNPoqGEqGL7TaHFOs6g,I7QITaqkoE-_lxQDjkhfeQ,vWOfTenuyEy1fUkI02veYg,rQUhciX3hkenlxDg9DunOg?mode=read&tenantId=8e148ee9-f5dd-42f8-87ec-612bfbe1cc4f

StrataBugs training webinars

With the release of v3.0, we’d love all of our users to become power users, so we are starting a series of short webinars covering all aspects of the system. Over the course of several weeks, it will form a complete training course.

The sessions will be free to attend for all StrataBugs licence holders who have a subscription or support contract. You do not need to attend each session, and if there is sufficient demand, sessions will be repeated.

Each session will be for no more than 45 minutes, and cover a main topic. There will be a talk for around 20 minutes then a Q&A session, demonstrations, and future topic requests.

The first session will be on Thursday 30th March at 10.00am BST. There will be a minimum and maximum number of attendees, so register early to avoid disappointment. The topic in this session is “Installing and getting started”.

This is suitable for anyone who hasn’t installed StrataBugs, or has a previous version and not yet installed v3.0, or who needs to manage their own system. The overview of the setup and main components might also be suitable for IT staff who need to support StrataBugs in their organisation.

A introduction to the function of the main components will also be given, and an overview of how to get started with StrataBugs.

If you would like to attend but the date and time is unsuitable, then please let us know so we can schedule an alternative in the future.

Contact us through this blog or by emailing, and we will send you a registration link.

StrataBugs examples in offshore wind turbine survey

It’s been a long time since the last StrataBlog post because we’ve been busy working on v3.0, which is out for pre-release testing.

In the mean time, we’d like to share with you links to some examples of StrataBugs being used in a shallow borehole study. Usually reports of this kind are proprietary and not available for general distribution. In this case the Netherlands Enterprise Agency have made available reports from BioChron which we are able to showcase the use of StrataBugs v2.1. In this report there are a series of embedded charts showing a multi-disciplinary approach using environmental grouping to resolve shallow stratigraphy relationships in combination with other age dating methods. These boreholes are drilled to determine subsurface conditions for suitability of wind farm pylon placement in the Southern North Sea.

The reports are available from the links below. You will need to scroll down to the lower part of the reports to see the chart examples.

Thank you to John Athersuch of BioChron Ltd. and the rest of his team, for sharing this with us. Further details are in the reports themselves.

Does StrataBugs run on Windows 11?

We are getting asked increasingly if StrataBugs is compatible with Windows 11. The chances are that if you’re in the market for a new PC, then it will come pre-installed with Windows 11, or be eligible for a Windows 11 upgrade. You may or may not welcome the new look and feel, but the good news is that we have found no compatibility issues with any version of StrataBugs.

We’ve only tested back as far as v2.1, but if you’re running an older version, why? Well, if you really have to, it will probably still run OK.

The new, more rounded window style, and slimmer scroll bars carries into the application and so far we’ve not spotted any functional problems. It’s up to you to decide whether to run with it, but don’t let StrataBugs stand in your way.

Bug in recalibrating sequence schemes

All types of schemes are scaled using abolute ages, which is why we tie biozone, sequence and composite standards to a chronostratigraphic scheme. The chronostrat scheme gives a reference to the age scale used in those related schemes. What happens when there is a new timescale published, like GTS2020?

Moving the boundary ages in a chronostratigraphic scheme can have basically two effects on the schemes which relate to it. Either the boundaries and events in the previous scheme move with the new boundary changes, or, zones and events find themselves in different chronostratigraphic units as a result of the change.


There has long been an option in the Schemes and Interpretations module to Recalibrate schemes, and this option makes the assumption that the former of the two conditions is always true: that if a chronostratigraphic unit changes its boundary age, then all the related content in linked schemes will change accordingly, and a new scheme can be saved where the boundary ages align with the new version of the timescale.

This works pretty well as a first pass way to create new versions of your schemes. however, for sequence schemes we’ve recently been alterted to a bug whereby the surfaces of the new scheme are not created: instead, the surfaces of the original scheme are updated. This of course isn’t the desired result!

The bug has been corrected in all current releases: v2.1.1, v2.1.1-14, and the test v3.0. Until you have updated to the latest version after 24 Mar 2022, do not use the recalibration tool for sequence schemes.

If you have previously done this and not spotted the resulting erroneous surface ages, then you can correct back to the original values by re-importing an XML/SBG file containing the original scheme, and during the import process use the “Update Surfaces” button to change the surface ages back to the original values. Contact us if you need further help.

No well data are affected by this.
