Description of the Service

Present the Present: FiMar for WEB is free operational coastal system of oceanography and marine meteorology for the Baltic Sea. It includes present state of the Sea, one week hindcast and 2 day forecast. Wind, waterlevel currents, waves, temperature, salinity and ice conditions are included. User may model the drift trajectories for objects of his interest in this virtual environment.

University of Latvia (UL) is promoting demonstration of operational, coastal Copernicus Marine Environment Monitoring Service (CMEMS) downstream service Present the present. This free service has been developed from the existing experience in delivering proprietary Copernicus Marine Services downstream service FIMAR to Latvian Armed Forces since 2004.

Aim of "Present the Present" service demonstration

The aim of the service is to maintain useful operational service for broad range of stakeholders whose activities are influenced by the Sea state.

Further, we aim at promotion of general interest in changing marine conditions, and understanding synoptic variations at sea.

We reach these aims via providing the virtual operational insight oceanographic and marine meterological parameters, their climatic context and allowing experimental drift modelling.

Geographical region:

Baltic Sea

Copernicus Marine Services Market:

    Primary: SAFETY & DISASTER

    Secondary: MARINE NAVIGATION

Type of service

Free operational downstream coastal web service - accessible by clicking ACCESS SERVICE button on the main panel

Brief presentation of the operational service

User may visualise selected scalar and vector fields, animate them, inspect conditions at points of interest, model drift trajectories in the Service. One week hindcast and 2 days forecast is available. Information is refreshed 4 times daily.

    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:

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.

Input data of the service

Data infrastructure: both atmosphere and oceanographic operational data are necessary for predicting the drift. Marine meteorology data are acquired from HARMONIE model driven by Danish Meteorological Institute (DMI). Oceanographic data from Copernicus Marine Services are used. 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).

Corpernicus Marine Services Products used in the Present the present service

The service benefits from the Copernicus Marine Services data. Derived product - drift solver is developed using operational data flow.

The following input data from Copernicus Marine Services Catalogue Regional Domain Baltic Sea (references according to Copernicus Marine Services Catalogue Overview December 2017 are given in brackets) are implemented in the service:

Usefulness of the Copernicus Marine Services information

The Compernicus Marine Services provides 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.

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 present service and its demonstration for (a) direct use of extracted fields in some of downstream products, (b) obtaining boundary conditions for UL_HBM operational setup, (c) providing comparison of model results with Copernicus Marine SST product.

Timeline

The final version of the service demonstration has been launched! In addition to previous versions the Stokes drift and longer time window (7 days in the past and 2 days forecast) have been added.

The Service duration is not limited.

Previous versions of the service demonstration:

  • Alpha release of the service was launched on November 2018: it included the operational data flow and visualisation (without the object drift model) with the time window 96 h (2 days in the past and 2 days forecast)
  • Beta version have been released on 15th of May, 2019, it includes the object drift (surface current and wind impact)

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
