A tidal atlas or a tidal stream atlas is used to predict the direction and speed of tidal currents. A tidal atlas usually consists of a set of 12 or 13 diagrams, one for each hour of the tidal cycle, for a coastal region. Each diagram uses arrows to indicate the direction of the flow at that time. A spring tide is a tide just after a new or full moon, when there is the greatest difference between high and low water. A neap tide is a tide just after the first or third quarters of the moon when there is least difference between high and low water. This tidal atlas covers Galway Bay which is situated on the west coast of Ireland. The data used to create the Galway Bay tidal atlas was derived from the output of an operational hydrodynamic model of Galway Bay. The Galway Bay tidal atlas is managed by Oceanographic Services within Ocean Science and Information Services section of the Marine Institute (Ireland).

Provenance information	The tidal atlas was created using tidal predictions derived from the output of a 200-metre resolution hydrodynamic model of Galway Bay. The modeled currents were validated against a limited number of ADCP deployments in the bay. A tidal atlas provides average spring and neap tidal currents and so can only ever be used to provide an estimate of actual conditions pertaining in the bay at any point in time.

Hi there when I try to download the charts I just get code

Hi, Thank you for your comment on this dataset. We have followed up with your query in Marine Institute and unfortunately there are no arrows available on this Web Map Service to indicate direction. Our apologies, we will update the abstract to reflect this. The service is available at http://atlas.marine.ie/arcgis/services/ModelProducts/MapServer/WMSServer?request=GetCapabilities&service=WMS if you want to view more detail as the image available on data.gov.ie is only a preview of the service. We are currently in the process of reviewing and updating this record. In the interim, if you would like more information on this dataset or have any specific requests we can help with, please feel free to contact us directly at the Marine Institute by submitting a request here: https://www.marine.ie/Home/marine-institute-request-digital-data.

Not working? Created 07.24.2021 21:39

This doesn't seem to work correctly in Edge or Chrome. I can't view the layer that shows tidal currents.

I can't see any arrows indicating direction of the tidal flows. Am I missing something?
