Open-access: Global Stable Isotope Dataset for Surface Water. The dataset consists of three main elements: website data from IEAE (GNIR), water isotope website from University of Utah, measured data and reference data - 22,432 surface water sampling sites across seven continents. Put together by Li et al (2025). Dataset link in the comments.Abstract"Hydrogen and oxygen... Continue Reading →
On this day exactly 10 years ago, I created a free community outreach blog for geoscience data and AI. Thank you to everyone for all the encouragement and support you have given over the years.The blog was initially focused on techniques leveraging content in documents - unstructured data, search (IR) and NLP, tying this to...

EarthScape: A Multimodal Dataset for Surficial Geologic Mapping and Earth Surface Analysis. Advancements in deep learning and the proliferation of remote sensing imagery present an opportunity to expand surficial geologic mapping, overcoming the limitations of tedious and biased traditional workflows.Interesting paper from Massey and Imran (2025) with supporting Open source code and data in GitHub....

My letter in the 'Geoscientist' raises serious concerns about Artificial Intelligence from the Deep-time Digital Earth (DDE) project, around lack of transparency, state censorship, and potential copyright infringement.DDE is an international geoscience Big Data and AI project endorsed by the International Union of Geological Sciences (IUGS) and led by China. The DDE accords were signed... Continue Reading →
Excellent paper published this month by Hinsby et al (2024) abstract below:Open access to harmonised digital data describing Earth’s surface and subsurface holds immense value for society. This paper highlights the significance of open access to digital geoscience data ranging from the shallow topsoil or seabed to depths of 5 km.Such data play a pivotal role... Continue Reading →
