Research
Interests
Processes driving the carbon sink in the oceans and
shelf seas. Seasonal, year-to-year and decadal variation in
the ocean carbon sink. The marine carbon cycle and its
feedbacks with other biogeochemical cycles and climate. Air-sea interactions of long-lived greenhouse gases (carbon
dioxide, methane, nitrous oxide). The role of seasonal
sea ice in air-sea transfer of carbon dioxide (CO2). The
key role of iron in the Southern Ocean carbon cycle. The
effects of climate change and ocean acidification on marine biota. Remote sensing. Maintaining time series. Safe
data storage. Access to marine biogeochemical data.
These topics are the focus of my research and my publications. I
coordinate research on Interactions of Marine
Biogeochemical Cycles and Ocean Physics.
Extensive measurements of surface water CO2 are an important means for
quantifying the oceanic uptake of CO2. As important is safe storage of and
access to these surface water CO2 data. The Surface Ocean CO2 Atlas (SOCAT) has created a synthesis product of
quality controlled surface water CO2 values for the global oceans and coastal
seas (Pfeil et al., 2013). The data are also available as gridded products
(Sabine et al., 2013). Version 2 of SOCAT has been made public at the 9th
International Carbon Dioxide Conference in Beijing, China (Bakker et al.,
2013). It has 10.1 million CO2 values spanning the period from 1968 to 2011.
SOCAT is a powerful tool for quantification of the spatial, year-to-year, and
longer-term variation of the ocean carbon sink.
SOCAT is also used for the initialisation and validation of ocean carbon
models.
The size of the Southern Ocean CO2 sink and the role of iron supply in Southern
Ocean carbon cycling are important themes in my research. I was part of
international teams of scientists, which tested whether low iron concentrations
limit phytoplankton growth in parts of the Southern Ocean. Iron additions
promoted algal growth in the SOIREE and the EISENEX experiments, thus
confirming iron limitation of algal growth in these waters. Natural iron
fertilisation occurs downstream of islands and in frontal systems in the
Southern Ocean. Large changes in carbonate chemistry of surface waters occur
during and upon seasonal ice melt. I (co-)supervise three PhD students which
investigate topics, ranging from the quantification of the global ocean carbon
sink, air-sea transfer of nitrous oxide, methane and carbon dioxide and uptake
of anthropogenic carbon by the Southern Ocean.
Ongoing research
projects include: SOCAT, CarboChange,
Antarctic Deep Water Rates of Export (ANDREX) and the UK Ocean Acidification Research
Programme themes 1 and 2. I have participated in 20 multidisciplinary,
mostly seagoing research projects and am a (co-)author of 45 peer-reviewed
scientific articles and 5 book chapters.
PhD studentships: The
Centre for Ocean and Atmospheric Sciences (COAS) at the University of East Anglia offers a vibrant
research community with specialists in biological, chemical and physical,
marine and atmospheric sciences. Highly motivated PhD candidates with strong
scientific interests are encouraged to contact me.
