My research focuses on past and present marine environments and their relation to climate and climate change foremost over the last 130 000 years. This research further includes the study on the interactions between land, sea, and atmosphere. My main tools are marine sediments with their contents of different microorganisms combined with instrumental hydrographic time series and process-oriented modeling. My research further addresses proxy calibration and validation both through experimental and field studies, i.e. improve the tools we use to reconstruct the past.
I find it especially intriguing to work in coastal settings, which are often affected by human impact, such as fjords, the Skagerrak and the Baltic Sea but also coastal upwelling areas around the world’s oceans. I lead a number of projects, financed from the Swedish research councils VR and Formas as well as the Crafoord Foundation, Oscar & Lili Lamm Foundation, Olle Engkvist Byggmästare Foundation.
Teaching: I’m course coordinator for the Master Course Global and Regional Marine Geology (GEON04) and partly for the Bachelor thesis course (GEOL01), I teach on several courses and typical supervise 2-3 Bachelor and Master Students per year.
the CONTEMPORARY project: Field and culture-based calibration of temperature and salinity proxies using benthic foraminifera: Some of the most significant challenges in palaeoclimate research arise from the need to both understand and reduce the uncertainty associated with proxy methods. The aim of the study is to estimate uncertainty in marine temperature and salinity reconstructions based on benthic foraminifera and improve regional bottom water temperature and salinity reconstructions.
