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 – 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.

I have a fully funded open #position for a PhD student/postdoc in marine #biogeochemistry. As part of the MARBEDS project, we are seeking someone to study seafloor fluxes and their interactions with microbial communities in biodiversity hotspots.

Overview of oxygen “stage” nomenclature used in this review. From top to bottom shows the ranges most often associated with the descriptive terms OMZ, oxygen-deficient zone (ODZ), anoxia, dysoxia/hypoxia, and anoxia in seawater. Oxygen concentrations are shown on a log-linear scale along with a simplified schematic of several proxy-relevant components of other redox-sensitive reactions. Chemical concentrations other than oxygen are non-dimensional, but all relate to scales. The redox ladder is modified from Canfield and Thamdrup (2009).

#WeekendReading: Hoogakker (and 67 other people) go into the current state of low-oxygen proxies currently in use in paleoceanography. It's a small book (95 pages), more than a paper, and covers a lot. 🧪⚒️

Deep-sea life is still recovering from mining activity 40 years ago The site of a deep-sea mining test in 1979 had lower levels of biodiversity when researchers revisited it in 2023 compared with undisturbed areas nearby

Part of the Pacific Ocean seabed was mined in 1979. 44 years later, marine life in the area has still not fully recovered www.newscientist.com/article/2469...

There have been people less than helpful in my journey here. I wanted to acknowledge those too, bc I know I am not unique in this experience. No thank you to the physics study assoc that made me sing songs about how women couldn't study physics without sleeping with the professor, the day I stepped into university life. No thank you to the 5th year physics student that decided to assign me a stripper name within the first minute of meeting me in the physics coffee corner in my first year. No thank you to the technician that was responsible for onboarding me on the use of the cluster in my third year who raised his eyebrows and asked me if that meant I was some sort of computer girl. No thank you to the senior researcher that sent me utterly inappropriate texts after a conference, then proceeded to apologise months later by telling me they had not been meant for me anyway so no hard feelings remain hopefully And no thank you to him for attending every conference I've been to since. No thank you to the people who told me that it was surprising that I was doing a PhD since I was a girl. No thank you to the man who mistook me for a coffee lady at a conference, and after having to correct him two times that I did not work there, responded with you should consider it. No thank you to the researcher that asked me what I was wearing underneath my outfit during a conference. No thank you to the physicist who declared to a room full of other physicists that biologists don't know how to design an experiment. No thank you to the people who have called me scary instead of strong and intimidating instead of intelligent. And finally, no thank you to the exec board of the TU Delft, whose knee-jerk reaction to being held up a mirror about the social safety at the university, was to sue the party holding up the mirror instead of looking at the problems they highlighted. ... You have made me feel like I do not belong in science & I cannot forgive you for that.

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.”

It's a huge honor to receive the Alfred Treibs Award and to be placed in a list of researchers that I have always looked up to. I owe a lot of gratitude to my colleagues and all ECR that have been part of the organic biogeochemistry group at NIOZ for always pushing me forward.

Coriander leaves and seeds, hating them is apparently the worst mutant power.

You know how some people like coriander and some can't stand it, but it seems there isn't anyone in between?
The thing is, not liking it - is genetic. A variation in one gene affects some people's olfactory receptors, which makes it taste like soap or dirt. 🧪
