25-Norhopanes have been reported in biodegraded oils since the late 1970s, and Seifert & Moldowan (1979) proposed that the methyl group at C-25 in the regular hopanes was removed by microbial demethylation associated with the degradation at the oil/water contact of an oil accumulation.

Clients using our ML tools often mention that it can be difficult to know which models to use. We generally advise users to start with the simplest appropriate model as a baseline (this is the default option), then to try additional models for comparison.
ML Team Lead
Last year we began a partnership with the North Devon Biosphere and launched a dashboard exploring continuous sensor data in the region. Since then, several data sources have been added including sample data collected by citizen scientists and Environment Agency (EA) bathing water quality.
ML Team Lead
Following the successful launch of the new IGI website, announced in the November 2025 newsletter, we have continued the modernisation across our other web-based platforms.
Product Owner
We are excited to share our latest newsletter, released alongside the newest version of our software. In this edition you will find details of our redesigned software user guide, plus an interesting feature on the Offshore Algarve Basin and its Geological Carbon Storage Potential.
Office Manager
We are delighted to release version 3. 0 of p:IGI+ and Metis. Version 3. 0 is a major update; it’s been in development for over a year, it was previewed at our 2025 user group, and has been used in two training courses.
