GNSS geek moment in Bremerhaven, that little hut and mast quietly doing sea level work while tourists photograph the BH. Local quality control inspector (seagull) on duty.

This week at ISSI we are hosting the Forum “Challenges and Advances in Remote Sensing of Coastal Sea Level with Ground-based GNSS-IR.” Bringing together ocean, sea level, and geodetic communities to advance GNSS-IR for improved coastal sea-level monitoring. forum.issibern.ch/remote-sensi...
Africa's first GNSS-IR network for water level monitoring is live in Cameroon! 8 low-cost stations, cm-level accuracy, validating Sentinel-3 & 6. Data: www.GNSS4SurfaceWater.com Code, workflows and fieldwork photos at github.com/MakanAKarega...
CRC 1502 DETECT@crc1502-detect.bsky.social · 3mo ago🌊🛰️ From Rhine to the tropics: low-cost GNSS-IR water-level sensors developed at @unibonn.bsky.social, under #CRC1502 #DETECT, are now used in ESA projects across Africa & the Asia-Pacific—supporting open monitoring for rivers and coasts in data-poor regions. 📰 www.uni-bonn.de/en/news/083-...
This madness and turmoil are growing day by day, hour by hour, yet we remain under the illusion that we are living among a peace-loving, civilized, and climate-conscious generation. What an illusion…

🧠 How are you, really? Today is World Mental Health Day - a reminder that caring for your mind is important. Kristin Vielberg and Hanna Sänger from PhDpositive reflect on the mental health challenges of doing a PhD and share ways to make the journey more sustainable, fulfilling, and balanced. 🌱
Climbing Through a PhD – Mental Health on the Way to the Summit
Imagine you are going on a long mountain tour. Your backpack is heavy, the path is steep, and although you have been walking for hours, all you can see ahead of you is the next climb. Doing a PhD is l...

Volcanism is a unique feature of Auckland. Newly discovered hidden faults make things even more interesting. This is a picture I took last Aug of the 50 m deep crater of Mount Eden (erupted 28,000 yrs ago).
Eos@eos.org · 11mo agoFun Fact for the Day: The United States considers a fault active if it’s ruptured in the past 12,000 years. In New Zealand, it’s 125,000 years.
Our PhD student Charlotte Hacker (@crc1502-detect.bsky.social @unibonn.bsky.social) published a 40yr record of total water storage anomalies (TWSA), similar to GRACE but from 1984 on. She combined SLR, DORIS and climate data in a new method. zenodo.org/records/1582... doi.org/10.22541/ess...
GNSS Hydrology is proposed to integrate GNSS hydrogeodesy and GNSS remote sensing. This framework provides a unified approach to studying the global hydrological cycle using GNSS technology. Read more in our recent Letter in The Innovation: www.sciencedirect.com/science/arti...

Your #paper doesn’t mean much if you don’t share the data and #code to reproduce the results. I’ve stopped reviewing #manuscripts with no transparent and open data policy.
Spent a couple of days around the Marmara Sea Islands and it’s surprising how much the locals know about earthquake risks.
Fieldwork yesterday in Todenfeld! GNSS is out there running.
