My main academic interests include: Antarctic, Arctic and Baltic sea ice ecology & biogeochemistry; Role of dissolved organic matter in aquatic systems and land-ocean transitions; Inorganic nutrients & phytoplankton primary production; Industrial-scale microalgal biomass production & utilisation; Seaweed & halophyte ecology & physiology; Conveying science to non-specialist audiences; Connections between science & art.

My work is international in scope (worked & lived - apart from UK - in Germany for 7 years; Finland for 2.5 years; Denmark 10 months; Israel for 6 months).

Since the award of my PhD in 1988 I have:

- Participated in 14 research-cruises of between 2 weeks and 3 months: Southern Ocean (6), Arctic (2), North Sea (5) & North East Atlantic (1). I have conducted other fieldwork in the Baltic Sea (Finland & Sweden), Red Sea (Israel & Egypt) & White Sea (Russia), The Philippines, Vietnam & Wales. I have also led teams of between 10 and 20 scientists in 4 large-scale facility ice tank experiments in Hamburg (≈30 days each).
