Wir wollen von Ihnen hören, Herr Merz!: Klimaschutz ist staatliche Pflicht – aber wird ignoriert

Der Klimawandel hat unsere Gesellschaft voll erfasst, doch die Bundesregierung setzt auf ein „weiter so“. Unser Kolumnist kann es nicht fassen.

Spring is here — kicking off a new season of data collection on our #sensorfield in Brandenburg 🌱📡 We’re excited for another year of research into seeding and tree growth, powered by high-resolution climate and soil moisture measurements from our sensor network! 🌲🌳🌡️

Excited to see this published! 🐄📡 Using GPS tracking, we explore how pastoralists in East Africa navigate resource variability through cattle movements. Great to be part of this work led by Mohamed Shibia 🙂 🔗 www.sciencedirect.com/science/arti... #Pastoralism #Livestock #EastAfrica #RemoteSensing

A cow carrying a GPS collar in a cattle herd (on May 9th 2014) grazes on a grazing unit in Irbi village, southern Ethiopia. Based on the published data, this area denotes a flat, abundant-vegetation, highly fluctuating grazing unit.

*** Data set alert *** We are excited to share our new 3D forest dataset 🌲🌳🌿💻📊 121 terrestrial laser-scanning plots across Europe, all scanned using the same protocol and scanner! From pines to oaks and spruce, it’s a journey through the continent’s forests in millimeter detail. #TLS #Riegl

Dataset structure of the advertised Terrestrial laser scanning dataset collection.
The collection contains 121 forest plots, each 50 x 50 m at 1 cm spatial resolution. The collection is structured in 5 campaigns, one in Galicia, Spain, one in La Palma, Spain, one in Ostlandet, Norway, one n Brandenburg, Germany and one in Czechia. For each campaign a picture of an example point cloud is shown.

Over the past year, we had the chance to take part in an art–science film exploring terrestrial laser scanning (TLS) 🎥🌲. Working with artists Stephen Cornford & Theo Stanley gave us a fresh perspective on how our forest data can be seen and questioned beyond science.

A new semester kicks off this week at Berlin’s universities - back to campus vibes! 🎓✨ Our team is ready for a winter term of teaching GIS & remote sensing at Lankwitz. Wishing students & lecturers alike a semester full of learning, discovery & good energy! 🚀📚🌍 #FreieUniversität #BackToCampus

We were delighted to host a research exchange with colleagues from @CzechGlobe 🇨🇿 in Berlin! 🌍 We discussed forestry-focused remote sensing, explored opportunities for future collaboration, and visited study sites like the #sensorfield in Brandenburg. 🌲📡 Thanks for the great visit! #TeamScience

We are visiting our study site in the forest. Under tall pine trees our technichian shows a station with a solar pannel that is used to send data collected on the site to an online dashboard.

Together we are looking at small oak seedings in mossy undergrowth that grow beneath the big pine trees to form a new forest generation. Some small oaks are tagged with numbered blue plates. Their size is remeasured every year. In the background one can see a station with sensors that measure air temperature, humidity and light intensity.

We dig up a soil sample to see how much organic material is present on the forest floor. One can see a small pit and one of our senior researchers feeling how sandy the soil is.

Our fieldwork is in full go – our team is out in the woods every day batteling rain, swamps, sheep and running from cows – the dangers you find in northern Europe 😉 – all with the #Riegl on our shoulders. But check out these stunning views we get in return! It’s all worth it. #RonnieRieglOnTour

We are getting ready to head to Norway! 🌲🌾🌲 Our team will collect terrestrial laser scanning data to on the connection between forest structure and biodiversity – we are looking forward to two weeks in the beautiful boreal forest north of Oslo. And we are prepared for swampy conditions 😉
