#DublinBay - Dublin Bay was we know it today looked very different three centuries ago, as TheJournal.ie highlights with a selection of enlightening historical maps.

As reported yesterday on Afloat.ie, this week marks the 300th anniversary of the decision to build the Great South Wall in an effort to solve the centuries-old problem of silting in the main channels to Dublin Port.

At that time, the area north of Townsend Street that today is the south Docklands did not exist, as the Liffey flowed right up to what was then called Lazar's Hill or Lazy Hill – while Ringsend was a sandpit that extended into the bay at the river's mouth.

The wall changed all that, as the land between was reclaimed and the Liffey's course straightened and strengthened over the 80 years of its construction.

Later change came to the Northside, too, with the construction of the Bull Wall – surveyed by Captain Bligh of 'Mutiny on the Bounty' infamy – as Marino, Fairview and the North Strand, so named for their then coastal locations, lost their sea views to land reclamation, and Bull Island was formed from the sand and silt that once claimed any number of ships on approach to the city.

The maps have been shared by the Dublin Port Company to coincide with the Dublin Bay Conference that takes place today (Wednesday 29 April) with a programme of lectures lined up to celebrate the construction of what was then the longest sea wall in the world.

#INLAND WATERWAYS - A new mobile app that guides visitors around the trails of Lough Derg has gone live, the Clare Champion reports.

More than 20 trails are included in the app, from walking to cycling, driving, cruising and canoeing.

The app - developed in partnership between Shannon Development and US firm EveryTrail - uses Google Maps and the GPS system in smartphones to pinpoint trails near the user's location.

Users can download route descriptions, images and notes, get directions to the starting point and follow the the pre-plotted course.

The Lough Derg Trails app is available for iPhone and Android devices.

Marine Science Perhaps it is the work of the Irish research vessel RV Celtic Explorer out in the Atlantic Ocean that best highlights the essential nature of marine research, development and sustainable management, through which Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. From Wavebob Ocean energy technology to aquaculture to weather buoys and oil exploration these pages document the work of Irish marine science and how Irish scientists have secured prominent roles in many European and international marine science bodies.
