INFOMAR, a joint venture by the Geological Survey Ireland and the Marine Institute, has launched a collection of 18 high-resolution bathymetric maps of Ireland’s coastal waters. The Blue Scale Map Series is the culmination of over a decade of work and highlights the unique and intricate landscapes lying beneath the waves. 

Each week, INFOMAR will release a new map of a different section of the Irish coastline. The latest in the series is the blue scale bathymetric map of Loop Head, County Clare on the Shannon Estuary. 

The area was first surveyed in 2009 on board the RV Celtic Voyager, with the INFOMAR team mapping a total of 162km2 of seabed along the River Shannon and west of Loop Head. Mapping continued in the region on board the RV Celtic Voyager, RV Keary, RV Geo & MV Cosantóir Bradán between 2011 – 2014, resulting in an area of over 2000km2 of previously unmapped Clare coastal waters being surveyed in high resolution.

Earlier this year, INFOMAR’s inshore team, on board the RV Galtee, continued mapping shallower waters beneath the Iconic Cliffs of Moher, Liscannor Bay and Kilstiffin Reef.

The Blue Scale Map Series offers a new and unique way not only to showcase the mapping effort to date but also to visualize and communicate complex scientific information to the wider public. As with all INFOMAR data, these high-resolution maps are available for free to download and have huge potential to communicate with local coastal communities and raise awareness of the importance of maintaining the health and integrity of our marine environment.

Ireland’s coastline is approximately 3,171km in length and boasts some of the most unique and dynamic marine environments in Europe. Since 2006, INFOMAR’s seabed mapping efforts have been instrumental in enhancing our understanding of Ireland's underwater landscape. The Blue Scale Map Series not only highlights the topography of the coast in remarkable detail but also paves the way for the future management of Ireland’s marine resource.

An underwater survey of Dublin Bay is expected to commence this Friday, (1st October 2010). It is part of a Dublin City Council (DCC) project to upgrade the Ringsend Wastewater Treatment Plant. Preliminary works will include a Bathymetric Survey of Dublin Bay and its approaches and last for a period of approximately one month. The area to be surveyed is attached in a Notice to Mariners issued by Dublin Port Company. The survey will be carried out by a 12 metre yellow hull catamaran "Xplorer". The "Xplorer" is fitted with A.I.S.

Shipyards

Afloat will be focusing on news and developments of shipyards with newbuilds taking shape on either slipways and building halls.

The common practice of shipbuilding using modular construction, requires several yards make specific block sections that are towed to a single designated yard and joined together to complete the ship before been launched or floated out.

In addition, outfitting quays is where internal work on electrical and passenger facilities is installed (or upgraded if the ship is already in service). This work may involve newbuilds towed to another specialist yard, before the newbuild is completed as a new ship or of the same class, designed from the shipyard 'in-house' or from a naval architect consultancy. Shipyards also carry out repair and maintenance, overhaul, refit, survey, and conversion, for example, the addition or removal of cabins within a superstructure. All this requires ships to enter graving /dry-docks or floating drydocks, to enable access to the entire vessel out of the water.

Asides from shipbuilding, marine engineering projects such as offshore installations take place and others have diversified in the construction of offshore renewable projects, from wind-turbines and related tower structures. When ships are decommissioned and need to be disposed of, some yards have recycling facilities to segregate materials, though other vessels are run ashore, i.e. 'beached' and broken up there on site. The scrapped metal can be sold and made into other items.
