The Marine Global Change group is within the Umeå Marine Sciences Centre and the Department of Ecology and Environmental Science at Umeå University in Sweden. Our research profile is multidisciplinary and this is reflected in the composition of the team. We conduct research on marine biogeochemistry, ecology, biology, geology, climate change and oceanography.

I am interested in the application of analytical chemistry to understand climate change and environmental response in terrestrial and marine systems. My background in environmental chemistry is applied to the analysis of environmental, water and biogeochemical samples and the field work associated. I maintain, manage and train members of the group in the Mesocosm Facility, Bio-Earth wet chemistry laboratory and Geographical and Earth Sciences' Isotope Facility.
Blue Carbon in a changing world: My interests are in the effects of anthropogenically induced climate change on coralline algal systems. I am using a variety of geochemical techniques to investigate how the ability of coralline algae to sequester carbon varies under a range of climate scenarios.
Visiting PhD candidate from HKU
Nitrogen cycling in coralline algae: My interests are in the cycling of nitrogen by coralline algae and the systems they engineer; in particular working with Nick's group at Glasgow I am asking questoins about coraline algal nitrogen cycling under global change.
Oceans on Acid: My interests are in the impact of ocean acidification on marine ecosystems over the past hundred years. Using coralline algae I am reconstructing high resolution records of ocean acidification in sites in Greenland, Scotland and Australia. A mix of geochemical techniques and ecological profiling is being used to investigate these changes
I’m interested in why some tropical corals are more resilient to environmental change than others. Coralliths are unattached, free-living corals that get moved around by wave action. This means they frequently experience variation in environmental parameters, such as light availability. My project aims to understand the limiting factors of corallith formation, why can only a handful of coral species form coralliths? And what ecological role might coralliths play in reef recovery and expansion, are they important in reef establishment and succession?
Postdoctoral Research Associate and previously PhD scholar
I am interested in the capacity of corals to survive in changing oceans. My research focuses on coral bleaching where I am investigating host-symbiont associations in the context of adaption or acclimation to place recent bleaching trends into an environmentally relevant context.
I'm interested in carbon storage by coastal habitats, especially by coralline algal systems. My research investigates both carbon burial processes and modification of benthic seawater chemistry by algal metabolic and calcification processes. My research uses both field work and lab experiments involving both stable & radio isotopes
I am generally interested in the evolution of biodiversity in the animal kingdom. In particular, I am keen on understanding in which way organisms are adapted to their environment and how this is achieved on the genomic level. Parallel evolution constitutes a strong framework to study how the environment has repeatedly driven the evolution of similar forms via natural selection. In this context, I am particularly fascinated how key adaptations have evolved independently in distinct lineages.
Many parts of the climate system, including impacts of freshwater input on polar oceans, are not fully understood. This limits our ability to determine the drivers of unexpected climate variations. My research uses oxygen and hydrogen isotopic fractionation during the land-ocean transit of freshwater to understand the 1) variablity of freshwater distribution in the marine environment, 2) the capacity of marine palaeoenvironmental proxies to record seasonal North Atlantic climatic variability and 3) the impact of freshwater on the climate system.
Breathing reefs: ocean-atmosphere carbon exchange of tropical coral reefs. Corals are ecosystem engineers that create morphological complex reefs, supporting some of the most diverse ecosystems in the oceans, yet climate change is rapidly altering their metabolic processes. My research focuses on quantifying patterns in air-sea CO2 gas exchange driven by coral reef ecosystems, both now and under projected climate change. My work will help determine the future role of the ocean in the carbon cycle.
Spatial coral bleaching patterns and processes: I am interested in the spatial distribution of Symbiodinium across the wider Caribbean region. My research aims to characterise the Symbiodinium communities associated with coral reef organisms at numerous sites across the wider Caribbean region in order to identify areas of high/low Symbiodinium diversity
