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:

  • 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:

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.
