EuskOOS is the Basque coastal operational oceanography system operated by Euskalmet along with the expert advice of AZTI technology centre. This system envisages three purposes:

• providing an accurate description of current sea conditions along the Basque coastline;
• offering ongoing forecasts of future sea conditions; and
• supplying ocean-meteorological products to Basque coastal users.

It was not in Normandy, but in Vendée on the French coast between latitudes 46º and 47º N, where the last wooden boats of the Life LEMA project have been appearing during the month of December. After being released in November near the Basque coast with the help of Gorka Ocio and the program VERBALLENAS.COM, they drifted for a little over a month towards the north with the intense winds from the south that hit the Bay of Biscay.

This week, Julien Mader from AZTI presented EUSKOOS Basque Operational Oceanography System at the MARTECH Workshop in Porto, Portugal. This was the eighth international workshop on Marine Technology which was held from the 10th-11th December 2018 at Porto University. The main objective of this annual workshop is to present and explore opinions on the latest investigations into current Marine Technology. www.martech-workshop.org/

A study by Bangor University and The Royal Society for the Protection of Birds in the U.K has proven to be able to extract tidal information using tagged Razorbills on the Irish Sea. By comparing mathematical current model with the movements of resting birds on the surface waters, they found that the changing position of Razorbills whilst resting at night would reflect the movement of ocean surface waters. Although measuring tidal data using seabirds has limitations, it shows great potential for inexpensive methods in providing crucial oceanographic data and can have uses in the marine renewable energy industry.

Calibration of HF Radar Antennas. This month the calibration campaign for high frequency radar antennas was carried out. During these campaigns, the pattern of the antennas that determines the direction of arrival of the received signal is adjusted; an important procedure to avoid errors in the surface current data offered by this system.
