Mikael Calner

Professor

Calner_Rödvig

I am a geologist (instagram: @thatscandinaviangeologist) with great love for Earth surface processes, depositional systems and the sedimentary rock record. My expertise area encompasses stratigraphy, sedimentary geology and geochemistry and palaeoecology. I teach in areas ranging from the microscopical world of rocks and fossils to deep time stratigraphy and the evolution of entire sedimentary basins. Many of my studies utilize continuous drillcores for sampling and I continously build the Calner Lab Drillcore Archive in Lund, which invites to cross-discipline collaborations. Besides research and teaching I have a great interest in academic leadership and has acted as director of the research studies in geology and as head of the geology department (2013-2018). I am a member of the Swedish National Committé of Geology (Royal Academy Of Sciences).

Calner Lab Drillcore Archive

A series of external grants have helped to recover more than 1.000 metres of stratigraphy from the Lower Palaeozoic of southern Sweden. These core sections are available in Lund for sampling for joint collaborations.

  • Lusklint drillcore (2022): Llandovery-Wenlock, Gotland (Ireviken Event) (Crafoord Foundation grant 20220567)
  • Kinnekulle drillcore (2016): Cambrian, Ordovician and basal Silurian of the Kinnekulle table mountain (Crafoord Foundation grant 20140806 and the Royal Physiographic Society)
  • Altajme drillcore (2015): Llandovery and Wenlock of Gotland (NSF PI B. Cramer)
  • Tingskullen drillcore (2010): Ordovician of Öland (GOBE) (Crafoord Foundation grant 20080860)
  • Borenshult drillcore (2007): Ordovician of Östergötland (LOME) (Crafoord Foundation grant 20050748)
  • Hunninge-1 drillcore (2004): Late Wenlock of Gotland (Mulde Event) (Crafoord Foundation grant 20030673)
  • Lindeberget-1 drillcore (2004): Early Ludlow of Gotland (Linde Event) (Crafoord Foundation grant 20030673)
  • Burgen-1 drillcore (2003): Ludlow of Gotland (Lau Event) (Swedish Research Council)
  • Ronehamn-1 drillcore (2003): Ludlow of Gotland (Lau Event) (Swedish Research Council)
  • Uddvide-1 drillcore (2003): Ludlow of Gotland (Lau Event) (Swedish Research Council)
  • Ottenby drillcore (unknown year): Middle Cambrian Bårstad and Äleklinta members (Borgholm Formation), 10 boxes, excellent condition.

Research projects

I am a specialist in depositional system analysis, sedimentary geology, sequence stratigraphy, and palaeoecology, and utilise fossil sediments and geochemistry to study the interplay of global change in climate, sea-level and biodiversity (minor and mass extinctions).

I work in particular with the Lower Palaeozoic sedimentary cover of the Baltic Shield with comparison to remote basins, in particular in North America and the South China Plate, but also in peri-Gondwana terrains such as the Iberian peninsula. Main lines of research concentrates on time intervals of major global change, in particular the Global Ordovician Biodiversity Event (GOBE), the end-Ordovician glaciation and mass extinction, and the series of minor extinction events in the Silurian. I have particular interest in the environmental drivers during these events.   

In modern carbonate sedimentology I focus on the the anatomy and mineralogy of recent and sub-recent ooids in the Bahamas complex and utilize synchrotron light FE-SEM and LA-ICP-MS to characterize the microworld and geochemistry of ooids. This project also aims to reveal the oceanographic and ecological significance of widespread calcareous oolites that developed in the aftermath of some of the mass extinctions in Earth history.

Teaching

My teaching focuses on sedimentary processes and products on wide spatial and temporal scales – from river systems and deserts in the continental interiors to the pelagic rain in the deep ocean, and from the Precambrian to the recent (e.g. BSc-level GEOB32, GEOB33). Students learn to identify ancient depositional environments through facies analysis and also to study how these systems evolved through time by means of sequence stratigraphy – in carbonate as well as clastic or mixed basins (MSc-level GEOM12). Since my research background mainly is within carbonate rocks, palaeoecology and palaeontology is a natural and well integrated part of my teaching. Most of my exercises and field excursions are based on either the 'old' marine Cambro-Devonian Baltoscandian basin of south-eastern Scandinavia or the eastern segments of the 'young' marine-continental Mesozoic Danish basin to the southwest. At the BSc-evel I also teach more applied geology, in particular about fossil fuels, including petroleum geology, coal deposits and carbon dioxide storage, and importantly, about the societal challenges associated with this industry. From 2023 I have expanded my teaching to include the public, in an online course centered on the bedrock geology of Sweden (MNXG02). In the Calner Lab Drillcore Archive in Lund I have assembled a little more than 1.000 metres of Palaeozoic intracratonic stratigraphy from Gotland, Öland, Östergötland and Västergötland provinces. These cores are central to my research on Swedish stratigraphy and, when possible, also used in my teaching.
