In my PhD project I use TSM derived from MERIS data that can be measured within approximately 10% bias. TSM derived from remote sensing can be used as indicator of coastal processes and remote sensing images provide us with a synoptic overview. I am currently working on my first article which is based on my Master thesis in which we show how TSM can be used to describe the extent of coastal processes. We are also planning to link up remotely sensed TSM and chlorophyll in coastal areas with terrestrial processes, using empirical relationship to hydrological parameters (inorganic N, Total P). The hydrological data will be compared and correlated with bio-optical components retrieved from satellite images in order to evaluate the effect of terrestrial and coastal management on water quality. The developed tools allow for the definition of the extent of coastal influence, seasonal fluctuations in river run-off, phytoplankton dynamics and concentrations of total suspended matter in the different sub-basins of the Baltic Sea. In Paper II we are planning to validate Sentinel-3 Level-2 data (reflectance and water products i.e. chlorophyll-a, suspended particulate matter, turbidity and Secchi depth).
On 9-13 May 2016 I will participate in Intercalibration Workshop where with various instruments will be measured bio-optical constituents. These measurements will be further used to validate Sentinel-3 products. Further, we are planning to have a 3rd longer deployment of the TACCS radiometer during Intercalibration Workshop week. The radiometer can be used to measure reflectance at sea surface and to validate the level 2 reflectance of OLCI. This is important as the level 2 reflectance is used to derive water quality parameters such as chlorophyll, SPM, CDOM, Secchi depth and Kd. The observation from the mooring at B1 will provide trend records of water clarity and potential changes in seasonal patterns using our own algorithms. Reflectance data will e.g. be used to derive backscatter, which is directly correlated to turbidity and TSM.
On 11-12 April 2016 I as well will participate in Lunch-lunch meeting at Askö with Tvärminne scientists.
On 22-23 September 2016 I will participate in Transdisciplinary Workshop that will take place at Askö Marine Lab. Workshop aims to bring together researchers, communicators and other regional stakeholders to discuss potentials to better utilize scientific advances in the Baltic Sea ecoregion. A central goal is to draft/outline a proposal targeting the 2017 Formas research call and identify relevant collaborators and partners. Within this workshop, we plan to assess existing governance arrangements, at both (a) EU and (b) national levels as they pertain to the water quality of the Baltic ecoregion. Once mapped out, strengths and weaknesses of those arrangements can be considered. In addition, we will consider the current state-of-the-science (understanding) of the connections between terrestrial nutrient sources to marine sinks as they pertain to reform options in terms of practical responses.
