I might test the university's health & safety department how many plants are allowed in the office 😂🤣. If I have to spent most, if not all of my 60% FTE position with administrative nonsense instead of the science, my funding agency believes I'm doing, I need art 🎨 and/ or plants 🪴🌺🌷 around me.

Almost a months ago, I attended a project meeting in Poland 🇵🇱. Since then, I have tried to get my travel expenses reimbursed. Let's see wether I am successful now after 3 expense claims have been rejected so far🤞🤞. 😤

Today is the big testing day at Fichtner & Schicht GmbH to see whether my #deepsea #incubationchambers work. 🤞🤞🤞

I’ll like to proudly introduce you to Dr @itziarburgues.bsky.social, my first PhD student who successfully defended her PhD thesis today 🍾🥳🥂. Almost on the day 2 years after I took over her supervision, she gave a really great presentation and excelled in the defense part.

Today and tomorrow I‘m in Barcelona 🇪🇸 at the @ub.edu for the PhD defence of @itziarburgues.bsky.social. So, let’s explore geosciences in Catalan.

The deep-sea incubation chambers can be deployed up to a depth of 6000 m and I used the predecessor version for the last 11 years, starting with my PhD for which they were developed originally. Now, I will finally get my own set, thanks to the #ERCStG project #SPYCLING (funded by @erc.europa.eu).

Today I visited the company (www.fi-sch.de/de) that is building my deep-sea incubation chambers. They are making great progress and I hope that they will have a successful equipment text next week, when I'm in Barcelona celebrating @itziarburgues.bsky.social PhD defense. 1/n

In addition, for the #JPIOceans project #MiningImpact3 I will study the (potential) recovery of ecosystem functions from preprototype #DeepSeaMining test 5 years ago.

This week, the 'Benthic Ecological Biogeochemistry' group at @marumunibremen.bsky.social is busy packing for the upcoming #SO322 cruise to the Clarion-Clipperton Fracture Zone (Pacific). For the @erc.europa.eu project #SPYCLING I will measure nitrogen cycling in sponges 🧽.

Today, I am extremely proud of my PhD student @itziarburgues.bsky.social as she is sending out the invitation to her PhD defense at @ub.edu (Barcelona, 🇪🇸). It was great pleasure and an honour to supervise her over the last 2 years, but now it is time to kick her out of the nest 🥚🐣🐤. #ProudPI

Honestly, I don't think that there are any spoilers. It's the first annual meeting since the kick-off meeting last year and we're all busy working on/ generating data and preparing for research cruises.

As I'm the technician in my own group (alias I can't afford an actual technician), I'm spending my Sunday evening ordering consumables for the upcoming cruise 🫠, before I travel to Poland for the #MiningImpact3 meeting #JPI-Oceans.

A couple of weeks ago, I had lunch with a colleague from another faculty, with whom I studied. We were talking about the different papers each of us are working on and today, I received a review request for 1 of those papers. Sorry editor, strong conflict of interest (for more than 1 co-author) 🤷‍♀️.

To transport my new costum-built deep-sea in-situ incubation chambers I am looking for transportation or flightcase boxes. I contacted several manufacturers and 1 already sent me a quote. Its manager was likely bored as he googled me before sending the quote, starting with Good day Dr Stratmann. 😂

Few years ago, a former #NIOZ colleague (Philip Riekenberg) introduced me to the concept of writing 100 words each day. I have adopted it and I also asked my new PhD student to do the same. Today, I wrote more words than I did the last 7 d, and I managed to sent the manuscript to the co-authors 💪.

My response was that it was indeed a misunderstanding, or better that the film team did not understand the difference between stable isotopes and radioactive isotopes. His response was: We will have 8 weeks on board to explain the differences 😅 (we might start with high school chemistry lessons) 3/3

Dr. Tanja Stratmann @drtanjastratmann.bsky.social · 08/07/2026
They had told him that I would work with radio tracers on board, and he wasn't sure whether that was a misunderstanding, or whether I really would work with radioactive isotopes, and whether I would need space in the isotope container 2/n.

The second campaign will be recorded by a film crew who are preparing 2 documentaries for 🇩🇪🇫🇷 television and we have discussed our individual plans with them, so they can decide what to focus on.

When you have purchased a new instrument with your #ERCStG funding and you realize that shutting down this instrument after installation (without touching the emergency stopp buttons) is more complicated than getting the grant in the first place 😵‍💫.

Last Friday, I went out into the field to collect marine sediment and seawater samples to prepare the bacteria 🦠culture that I will enrich in 13C & 15N. Later-on this culture will be fed to sponges and bryozoans in 3 experiments I will conduct until the end of this year. #SPYCLING

I have reached a stage in my career, where writing a paper is actually relaxing, because all the other tasks are mainly keeping a flea circus alive 😬 (including PhD defense of my first PhD student, preparing for field work, research cruises, setting up labs and instrument installation, etc.).
