Satellite data for monitoring ecological status of Lithuanian lakes: stakeholder meeting in Zemaitija National Park
One of the tasks of TODAY project is to enhance water quality assessment, algal bloom forecasting and monitoring system of Lithuanian surface waters by using Earth Observation (EO) data and developing EO based products relevant to the Water Framework Directive (WFD).
For several years, cyanobacteria accumulations observed at Plateliai lake raises a number of questions to locals and Zemaitija National Park environmental professionals. So in 2017-2018 scientists from Klaipeda University Marine Research Institute (KU MRI) analysed ecological status of Plateliai lake. Chlorophyll-a, suspended particulates, nitrogen and phosphorus were analysed, new algorithms allowing to identify the distribution of chlorophyll-a from Sentinel satellite images across the whole Plateliai Lake area were developed. In addition, the spread of macrophytes (reeds) on the shore of Lake Plateliai were mapped using drone and Sentinel-2 satellite images.
In 2019 January 11 KU MRI scientists dr. Diana Vaičiūtė and dr. Martynas Bučas together with the team presented and discussed the most relevant research results to the Zemaitija National Park and Plateliai community.
Research of Plateliai lake will continue in 2019 in order to answer in which parts of the lake higher algae concentrations are typically observed and what may be the causes. Other water quality parameters (suspended particles, water transparency, temperature and vegetation) will be also analysed using Sentinel and Historic Landsat Satellite Data.

Investigations of Lithuanian water bodies using COPERNICUS Sentinel-2 satellite data
In August 28-30, 2018 Diana Vaiciute, the scientist of Marine Research Institute at Klaipeda University participated in an international scientific seminar “Joint 2018 GEOAquaWatch and GloboLakes Meeting: Water Quality Information for the Benefit of Society“ held in University of Stirling (UK).
Together with the team from Klaipeda University: Marija Katarzyte, Martynas Bucas, Iveta Gecaite, Jonas Gintauskas, Edvinas Tiskus and colleagues from CNR-IREA (Italy) Mariano Bresciani ir Claudia Giardino, D. Vaiciute presented the first results of both H2020 EOMORES and TODAY projects.
The possibilities of COPERNICUS Sentinel-2 data application for operative water quality monitoring in Curonian Lagoon, Kaunas Reservoir and two Lithuanian lakes (Pleteliai, Dusia) were presented together with the practical use of satellite-imagery based information for mapping of algal biomass and bathing water quality monitoring.
