Volcanica

Making volcano research available for all.

Run by a team of dedicated volunteers, Volcanica [ISSN: 2610-3540] has published six issues of high-quality volcano-centric research since its launch in late 2017. Thanks to the enthusiastic efforts of our volunteers and an institutional sponsor—Presses universitaires de Strasbourg—we are able to ensure that the typical costs associated with publishing and accessing academic research are not passed on to the authors, the readers, their grants, or their institutions. Check out our archives here, or find out more about submitting research articles here. For more information, refer to the article below, or feel free to email me directly.

EarthArXiv

A free preprint service for the Earth sciences.

Hosting your research as a preprint can have many benefits. Once they pass moderation, preprints are citable and shareable immediately. This affords authors the opportunity to receive helpful feedback from a wider pool of researchers, can help establish research primacy, and appears to result in a citation advantage relative to non-archived research articles. For more information, visit https://eartharxiv.github.io, refer to the article below, or feel free to email me directly.

FJN is run by a Board of Directors and has an Advisory Board, all of whom are volunteers. Its mission is to support the ecosystem of diamond open access journals. For more information, visit https://freejournals.org/ or feel free to email me directly.

Field mode

Context is key.

I've carried out fieldwork at Volcàn Colima, Isla Socorro, and other locations in Mexico, as well as Mount Etna (Italy), Mount Ruapehu and Whakaari (Aotearoa New Zealand). Resourcefulness and creative thinking are often essential in these volcanic areas, especially when dealing with temperamental (and/or home-made) research equipment.

Lab mode

If you want something done right cheap, do it yourself.

As well as using lab apparatus, I broke some of it and (more importantly) learnt to fix it again. I am always keen to design and build research equipment to answer existing geoscience questions, and to find new ones.

Desk mode

Keyboard warrior.

Data is at its best when it is effectively visualised. A key aim of mine is to ensure that data is accessible in all its forms, and that includes on the page.
