User information


I am an ecotoxicologist with specialty in environmental
impact assessments and the transfer of pollutants/substances across
air-water interfaces. CEO of BNR Ecotour Consulting AB, an environmental consultancy firm in Sweden. In the ASCOS project I will be responsible for
collecting sea-surface microlayers as a sub-contractor to Bigelow Laboratories for Ocean Sciences (Matrai et al.).

With the help of radio controlled catamaran boats the surface film (upper 1/10 mm) is scraped off the surface of the open leads. Collected in bottles inside the catamaran hull and at hourly intervals transferred to coolers for handling in the laboratory on board Oden, many liters of microlayer material are to be delivered.
