Description of the Service
Present the Present: FiMar for WEB is free operational downstream coastal service of oceanography and marine meteorology for the Baltic Sea. User may model the drift trajectories for objects of his interest in its virtual environment. Its funcionality:
- The drift motion visualisation - wind & surface current & wave (Stokes drift) impact included - user initiated drift simulation of user selected floating objects starting at user selected time/location (1 hour temporal resolution)
- default wind factor available from the dropdown (suitable for the drift motion of a raft, a person or a boat)
- user defined wind factor on the drift motion available
- Sea surface contourplots (wave height, water level, current velocity, water temperature, salinity, ice thickness, wind speed, air temperature, drift velocity)
- Sea surface vector-(direction-) plots (current, wave, wind, drift)
- Sea surface contourplots of the climatic anomalies (deviation from the climatic mean of the 15 years in the past) for 2 oceanographic parameters: Climatic anomalies represent deviation of the sea surface temperature and water level in comparison with its climatic average (previous 15 years using 11 days frame - 5 days around the date for water level, 7 days frame - 3 days around the date for sea surface temperature).
The service provides the present state, one week hindcast and 2 day forecast. Its information is refreshed 4 times daily.

Targeted end-users
The primary stakeholder groups targeted by Present the present demonstration are State Environmental Services (which performs among others a) state control of environmental protection and utilisation of natural resources according to normative regulations; b) participation in managing of emergency situations), Latvian Centre on Geology, meteorology and environment, Latvian Firefighting and rescue service, Scientific Institute of Food Safety, Animal Health and Environment (having national responsibility in fields of Fisheries and Aquaculture in Latvia). The secondary stakeholder groups are tourism industry, interest groups (leisure, kiters, surfers, yachtsmen) public, particularly students and teachers.
Benefits for end-users
General benefit of the service is related to prevention of pollution in marine environment and strengthening marine data literacy in society of Latvia. Visualizations of the drift trajectories are raising awareness and understanding of environmental issues in the Baltic Sea (e.g. marine litter issues) as well as serving lost-and found purposes.
Copernicus Marine Services Products used in the Present the present service
The following input data from Copernicus Marine Services Catalogue Regional Domain Baltic Sea (references according to Copernicus Marine Services Catalogue) are implemented in the service:
- BALTIC SEA PHYSICS ANALYSIS AND FORECAST - physical state of the Baltic Sea near real time;
- BALTIC SEA WAVE ANALYSIS AND FORECAST - modelled near real time wave data;
- BALTIC- IN-SITU OBSERVATIONS YEARLY DELIVERY IN DELAYED MODE (1990-2015);
- EUROPEAN OCEAN- SEA SURFACE TEMPERATURE MULTI-SENSOR L3 OBSERVATIONS - satellite data of Sea Surface Temperature SST;
- BALTIC SEA- SEA SURFACE TEMPERATURE ANALYSIS - satellite data of Sea Surface Temperature SST;
The first two data layers are implemented in the service operationaly. Observation data layers have been implemented for verification and calibration of the service.
Derived product - drift solver is developed using operational data flow. Both atmosphere (wind speed) and oceanographic (surface current & wave height) operational data are necessary for predicting the drift. Implementation of sub grid precision for oceanographic data in the vicinity of certain areas is done by running operational Hiromb-BOOS model at University of Latvia (UL_HBM). UL_HBM implements the bathymetry by EMODnet, October 2018 with the most recent data for Latvian territorial waters. UL_HBM resolution 1 nautical mile.
The service benefits from the Copernicus Marine Services data. Oceanographic data from Copernicus Marine Services are used. Marine meteorology data (air temperature, wind speed) are acquired from HARMONIE model driven by Danish Meteorological Institute (DMI).
Integration of the Copernicus Marine Services information
Existing information system FIMAR as well as our operational oceanography model setup UL_HBM that has been developed by UL recently (in 2014-2017) are working examples of successful downstream usage of Copernicus Marine Services information.
Data is used in the service and its demonstration for
- direct use of extracted fields (contourplots of wave height, water level, water temperature, ice thickness, current velocity, salinity & vectorplots of current, wave) in the service,
- obtaining boundary conditions for UL_HBM operational setup (drift trajectory & drift velocity calculation that takes into account improved bathymetry along the coastline of Latvia),
- calculation of the climatic anomalies (deviation from the climatic mean) for sea surface temperature and water level,
- verification and calibration.
Usefulness of the Copernicus Marine Services information
The Copernicus Marine Services provide gridded data of Sea surface parameters either directly used in the Present the Present or used as boundary conditions for our operational model. Thus, Copernicus Marine Services information is a cornerstone of our Service. The Marine community of Latvia benefits from implementation experience of Copernicus Marine Services due to its induced fostering of cooperation between different user groups -specialists in government, public and private sector, scientists and students in natural and environmental sciences and humanitarian field etc.

We are proud that initial microplastics pollution drift studies of our team with the methods that have been implemented in Present the present service has resulted in 3-dimensional pollution backtracking analysis by Frishfelds et.al. published in Frontiers in Marine Science. Results show higher pollution densities closer to the mouth of the rivers Daugava and Lielupe. Potential pollution source and its evolution in time in the Gulf of Riga and Daugava estuary coastal system in summer 2018 has been investigated

We are glad that we have provided 4700 drift calculations to our users since we added the drift modelling functionality in April 2019. The map of the trajectories provided shows that the service has been used in almost every part of the Baltic Sea
