The unprecedented surge in during the early 2020s was primarily driven by a temporary decline in (OH) radicals, which reduced the atmosphere's ability to break down the gas, coupled with increased natural emissions from wetlands due to wetter conditions.

I got an #OpenPosition (fully funded) for a PhD student/postdoc in #marine #biogeochemistry. As part of the MARBEDS project, we are looking for someone to study #seafloor fluxes and their interactions with #microbial communities in #biodiversity hotspots.

Contact me if you would like more details.

(Was hoping to post this in June, but getting the ducks in a row took a while)

Open position for PhD student / Postdoc in biogeochemistry
For a fully funded four-year project exploring environmental and
ecological dynamics in the Mediterranean and Red Sea, we seek a top
tier PhD student or postdoc. The project aims to understand the
formation and persistence of biodiversity hotspots, especially in light of
global climate change and local stressors. The ultimate goal is to
gather insights across different organizational levels, from molecular,
organismal, and community to habitat structure and biogeochemical
pathways, in order to construct comprehensive models that forecast
the future dynamics and fate of these ecosystems under changing
conditions. This position would be focused on a key aspect of this
project โ€“ the variability of seafloor fluxes and their interaction with the
microbial community to facilitate the habitability of shallow (up to 40 m)
and mesophotic (up to 200 m) biodiversity hotspots such as reefs.

Interested candidates, please contact by email Dr. Or Bialik (obialik@ocean.org.il) or Prof. Eyal Rahav (eyal.rahav@ocean.org.il) with a letter of motivation, CV, and contact details of at least one referee for this post not later than the 28th of August 2025.

First session of 2025 British Organic Geochemcal Society meeting, hosted by Bristol OGU, just finished. Topics included Py-GCMS & FTIR characterisation of plastic particles, methionine methylation of brGDGTs, food transport through lemur using deuterium label and HRMS for forensic profiling of soils. A fantastic broad range of topics.

7.8: Why Do These Cancelled Science Grants Matter?

In this episode, Christina talks to Dr Gabriel Filippelli - one of the first scientists to have a running project canceled by the Trump administration. This fascinating interview reveals just how important internationally these American grants can be, and Dr Filippelli passionately describes this unprecedented attack on science and education and what we all lose when the work that scientists do grinds to a halt or is extremely politically curtailed. It's important, he tells us, to support the institutions that you care about and are vital to the continued knowledge of how to survive our climate-changed future.

Dr Filippelli is the Chancellorโ€™s Professor of Earth Sciences at Indiana University Indianapolis and the Executive Director of the Indiana University Environmental Resilience Institute. He works at the junction between biogeochemical cycles, climate change, and human health.

Dr Filippelli has also written the book Climate Change and Life: The Complex Co-evolution of Climate and Life on Earth, and Beyond, which explores Earth's ecological resilience to the great changes in climate that have occurred over the history of the Earth. He was also part of the driving force behind Climate Change and Resilience in Indiana and Beyond, which details local efforts to reduce the risks and lessen the harmful impacts of climate change, as well as prepare for the unavoidable consequences of climate change.

Let's talk about whales! ๐Ÿณ

I usually speak mainly about the potential role of human urine and feces as fertilizer for agriculture because humans are the only species to actively mishandle excreta.

But obviously, the excreta of various animals also play important roles in natural cycles โ™ป๏ธ

Many people might know that seabirds compensate some of the nutrient loss to the sea since they hunt fish at sea but excrete on land
But of course, the bigger the animal, the larger the amount of nutrients they can transport.
A recent study looks at whales and the role they play moving nutrients around, as they feed in a region, then migrate and pee in another!
nature.com/articles/s41467-025

In fact they contribute more to nutrient transport than birds and natural phenomena and could be a dominant factor in some marine biogeochemical cycles, thus regulating local carbon cycle and biodiversity. In the past, before we hunted them down, whale pee might have shaped entire ecosystems...
