Conferences in Borucino and Poznań
In recent weeks, Sambor Czerwiński participated in two scientific conferences. The first was The Global Water Future: A Holistic Approach to Water Monitoring and Conservation, held on September 17–19, 2025, in Borucino at the Water Monitoring and Conservation Center of our university. Sambor co-organized the event and presented the following talk: Shortly after, he attended […]
Paper in ESR – multiproxy research on peatlands
Our colleagues from Instytut Geoekologii i Geoinformacji UAM, in collaboration with Sambor Czerwiński, have undertaken a summary of the latest advances in peatland research using a multiproxy approach – combining various indicators such as pollen, plant macrofossils, testate amoebae, biomarkers, and stable isotopes. Peatlands prove to be exceptional archives of climate change and human impact […]
Paper in QSR – crater lake Alchichica
In our latest publication, we return to Mexico, to the semi-arid Cuenca Oriental region, which has long been inhabited by agricultural civilizations. The article presents new data from the Alchichica crater lake, located 18 km from the ancient city of Cantona (600–1050 CE). Isotopic data allowed us to identify three major drought periods: (I) ca. […]
Visit in Spain – Alicja Bonk
Between September 1st and 4th, Ala Bonk visited Spain, where she met with Pablo Corella from the Museo Nacional de Ciencias Naturales in Madrid and Graciela Gil-Romera from the Instituto Pirenaico de Ecología in Zaragoza. She brought back two short sediment cores from Lake Arreo – the first step toward collaborative research on the history […]
Biebrza NP – fieldwork
A few days ago, Alicja Bonk, together with our recent graduate Ola Orłowska and future bachelor’s degree recipient Barbara Biały, visited Biebrza National Park. The purpose of the trip was to collect research material following the extensive fire that swept through this unique area in April of this year. We extend our heartfelt thanks to […]
Publication in JoPl – Lake Gorzyńskie chronology
In recent days, the first paper on Lake Gorzyńskie, our new site with varved sediments, was published. In an article in the Journal of Paleolimnology, we present the chronology of the sediments, an initial look at their chemical composition, and our preliminary thoughts on the potential of this unique archive—our record extends back approximately 13,250 […]
Journal of Environmental Radioactivity – peat dating
Determining the age of geological material is a fundamental issue for reconstructing environmental changes. A recent article co-authored by Sambor Czerwiński compares different models used in dating peats by lead (Pb-210 isotope). Independent methods verified dating results: radiocarbon (C-14) and plutonium isotopes (Pu-239+Pu-240). The study was conducted on different peatlands, analyzing how the Pb-210 isotope […]
Sambor Czerwiński’s lecture
Last week, Sambor Czerwiński visited the Center for Ecological Information and Education in Gdańsk, where he presented on the topic “Nature’s Archives – History Recorded in Lakes and Peatlands.” During the lecture, Sambor provided the audience with information about the secrets hidden in lake sediments and peat, and how geological information complements findings from historical […]
Publication in Geophysical Research Letters – 10800 years of temperature change
From 2014 to 2024, there hasn’t been a year without at least one published paper about Lake Żabińskie. In the latest publication, we examine the variability of warm season temperatures throughout almost the entire Holocene with exceptionally high, 3-year resolution, all based on varied sediments and µXRF scan results. We invite you to read it! […]
November lecture for high-school
Our Department strives to demonstrate social engagement and initiative, especially towards younger science enthusiasts. On November 7th, we hosted students from the I Academic High School named after Distinguished People of the Sea in Gdynia. They visited us to learn about lake sediments and varves by participating in the classes titled “In the Microcosm of […]
