Wicklow Coast

Overview

Wicklow is located on the east coast of Ireland.

INFOMAR Survey History

INFOMAR surveys of the Wicklow coast began in 2003 when the Celtic Voyager mapped an area off the Bray coastline.

The Celtic Voyager returned in 2009, 2010, 2011 and 2012 and mapped the deeper offshore areas.

In 2016, the RV Geo, RV Tonn and the RV Keary focused their efforts on the shallower areas of seabed near the coastline and also the RV Keary completed coverage of the Codling and Arklow banks.

Shaded Relief

The 3D appearance is achieved using software called Fledermaus. By using some vertical exaggeration, artificial sun-shading (usually as if there is a light source in the nw 315°) and colouring the depths using various colour maps, it is possible to highlight the subtle relief of the seabed. This helps us to quicklyunderstand the variation in depths.

Shaded Relief of Wicklow coast from Newtownmountkennedy to Gorey (Click image for more detailed map)

Distinct features evident on the left image are a Sand Bank to the west, a soft sediment slump on the eastern edge of the sand bank and sandwaves on the seabed to the east of the sandbank.

The image on the right shows an area of seabed with sandwaves, scoured substrate (green) and megaripples. The image is characteristic of the varied seabed within the survey area. The megaripples axes are predominantly orientated east – west, indicating maximum current flow is along north – south and reciprocal headings. The megaripples are symmetrical and sinuous in character. Wavelengths are approximately 10 – 12 m.

Backscatter

Multibeam Systems also collect additional information, including the strength of the acoustic signal (or return) from the seafloor. This is known as Backscatter. Differing seafloor types, such as mud, sand, gravel and rock will have different Backscatter values depending on the amount of energy they return to the sonar head. Rocky areas will typically have high returns while soft sediments like mud are more likely to absorb energy and have low Backscatter returns. These differing values are used to generate a grey-order image (i.e. dark for high returns, bright for low returns) of the seabed which can be used toexamine the nature of the seafloor.

Backscatter image showing the Seven Fathom Bank clearly in bright colour indicatiing a low return. Soft sediments like sand are more likely to absorb energy and have low backscatter returns. Seabed samples taken on the bank also verify that it is sand.

Ground Truthing/Seabed Sampling

To verify the results of remotely sensed sonar data, it is important to collect physical sediment samples from the seabed. These may be from the surface where grabs are used or may penetrate through the seabed and retain the vertical structure of the sediment by using various coring methods. These samples are also critical for the confirming seabed classifications.

Seabed sampling was undertaken in 2005, 2011 & 2012 by the Celtic Voyager. INFOMAR also carried out some sampling in 2008.

Seabed Habitats \ Seabed Substrate

The seabed substrate information has been derived from a combination of the analysis of geophysical data (multibeam echosounder bathymetry and backscatter) and groundtruthing data acquired as part of the INSS and INFOMAR seabed mapping programmes.

EMODnet Geology WP3 Seabed substrate map. This is a broadscale map (1: 250 000 scale) showing areas of similar substrate as collated  and harmonized from  EMODnet-Geology partners.  


The area contributed by GSI covers 17 indexed offshore areas within Ireland’s Territorial Claim on Continental Shelf. and is classified using Folk schema (7 classes) as developed for EMODnet Geology.

The shapefile can be downloaded from the EMODnet Geology website.
