A new subsurface temperature model for Ireland from joint geophysical–petrological inversion of seismic, surface heat flow and petrophysical data SUMMARY. High-quality maps of subsurface temperature and the geothermal gradient are useful when assessing the geothermal potential of a region. However, d

The models are freely available open access through GJI (doi.org/10.1093/gji/...) in the supplementary material, as well as through the GSI web viewer (www.gsi.ie/en-ie/data-and-maps/Pages/default.aspx).

2 maps of Ireland. The left hand figure shows the depth to the Moho (thickness of the crust) which ranges from 25 to 33 km depth while the panel on the right is the same but for the lithosphere asthenosphere boundary depth (78 to 118 km depth).

The inversion also produces outputs for the depth to the LAB, Moho as well as determine Vs and radiogenic heat production. These new results will be useful for future geodynamic modelling studies and understanding Ireland's tectonic history.

The results allow us to determine the geothermal potential and provide a range of temperatures based on the uncertainty and variability of the input parameters. The associated uncertainty maps and likely ranges, were an important part of producing the models

4 panels of subsurface temperature models of Ireland. These range from 2 to 30 km depth with the warmest temperatures in the North and cooler temperatures in the south.

We've used phase velocity data combined with variable surface heat flow, thermal conductivity and radiogenic heat production to model the crust and upper mantle across the island.

New subsurface temperature models for Ireland have been published! In this work we used a joint geophysical petrological inversion to solve directly for temperature.

Today is the LAST CHANCE to nominate for our 2026 RAS Awards🏅🏆

Among them is the prestigious Gold Medal – the Society’s highest honour – which dates back more than 200 years and has previously been won by Albert Einstein, Stephen Hawking and the new Astronomer Royal, Michele Dougherty.

It was great to talk to @siliconrepublic.bsky.social about my work on geothermal energy. Thanks for the opportunity!

Being Too Helpful At Work Can Hurt Your Career—Here’s How To Say No Women are more likely to take on behind-the-scenes duties at work—extra tasks like onboarding or event planning—and it's hurting their careers. Here's how to say no.

In a study of professors, women got 378 new work requests over 4 weeks vs 118 for men. Women spent more time on service, advising & teaching; men on research. Orgs should track who is taking extra duties & ensure they are rewarded and distributed fairly. www.forbes.com/sites/kimels...

Something is ‘pulsing’ beneath the Earth – and it could tear a continent apart Rhythmic surges are like a ‘heartbeat’ under the ground

Something is ‘pulsing’ beneath the Earth, scientists say – and could tear a continent apart

Magma "heartbeat" is tearing continent apart, geologists discover "The plume is pulsing," said Earth Science professor Tom Gernon of the University of Southampton.

Just ordered one! Excellent design. Definitely recommend ordering one ASAP

An image of a fence surrounding a solar panel, with Eoghan Totten installing a new panel for the fence to keep cows away from the solar panel and seismometer. It's in the corner of a field with a tree in the very corner.

Excellent 2 days of fieldwork for the GRANNUS and MOD3LTHERM projects. 100% data recovery in Northern Ireland and we installed a fence to protect the equipment from cows. Thanks to Eoghan Totten @dias_geophysics
and Rob Raine @GeoSurveyNI for making this possible #Diasdiscovers.

Look out for our next paper which will show the full subsurface temperature maps of Ireland using this method Thanks to @SEAI_ie and @GeolSurvIE for funding the research as part of the DIG project dig-geothermal.ie 4/4

A map of the thermal conductivity of Ireland

The main controls on the temperature gradient were lithospheric and crustal thickness, however, thermal properties also significantly influence temperature with warmer geotherms found in granites and muds.

A series of 6 plots showing the direct temperature measurement and the calculated temperature using our new model. We also plot 2 previous studies results at the same locations.

New surface-wave measurements across Ireland were used with thermal property, surface heat flow, Elevation and Moho depth data in the inversion procedure. We compared to direct temperature measurements in Ireland and found the model reproduced temperatures within error

📢New paper alert! Here we present a new approach to calculate subsurface temperature in areas with limited direct borehole measurements. We use Ireland as a case study to test the workflow.
