New Archaeological Discoveries in Galway Bay

#GALWAY BAY NEWS - Archaeologists in Galway Bay have unearthed an extensive tidal weir complex at Barna and a late medieval quay on Mutton Island, The Irish Times reports.

The weir, which is estimated to date from the early Christian period, consists of a granite barrier with channels cut through it, designed to control the flow of water in the adjacent lagoon.

Connemara archaeologist Michael Gibbons suggests that the weir implies a considerable fish stock migrating through the area into the Barna river.

The remains of a large Iron Age fort which overlooks the site may also have given its name to the townland of Knocknacarra, which is now a populous suburb of Galway.

Meanwhile, further east at Mutton Island a medieval quay which predates the current lighthouse quay has been found.

Shackleton Spearhead's Into Dublin Bay

Lord Mayor of Dublin and Admiral of Dublin Port, Gerry Breen, performed the 523 year-old "Casting of the Spear" ceremony in Dublin Bay on midsummer's day, writes Jehan Ashmore.

The 'casting' for yesterdays' re-enactment by the Lord Mayor took place onboard the Dublin port Company tug Shackleton.

From the deck of the Spanish built 50-tonne bollard pull tractor-tug, a spear was launched into the sky and fell deep into the cold water's of Dublin Bay. The ceremony once again marked the position of the city boundaries eastwards.

The medieval tradition of 'Casting of the Spear' dates back to 1488 when the then Lord Mayor, Thomas Mayler, set out on his horse to ride the city's boundaries.

According to historical records he rode out onto the strand as far as a man might ride and from there he cast a spear into the sea. At that time, casting the spear demonstrated the extent of the city boundaries eastwards.

The tradition marks one of many significant moments in Dublin Port's long history since its establishment as a trading post some 1,200 years ago.

About Marine Technology

Marine technology, as defined by the European association WEGEMT, refers to the use of technology for ensuring the safe use, exploitation, protection of, and intervention in, the marine environment. This includes a wide range of technologies that support naval architecture, marine engineering, ship design, ship building, and ship operations.

In addition to these foundational technologies, marine technology also encompasses oil and gas exploration, exploitation, and production, hydrodynamics, navigation, sea surface and sub-surface support, underwater technology and engineering, marine resources (including both renewable and non-renewable marine resources), transport logistics and economics, inland, coastal, short sea and deep sea shipping, protection of the marine environment, and leisure and safety.

The importance of marine technology cannot be overstated. With over 70% of the earth's surface covered by water, the marine environment plays a critical role in our lives. From transportation to energy production, marine technology enables us to harness the immense potential of the oceans while minimizing the impact on the environment.

Moreover, the development of marine technology is crucial for the sustainable use of marine resources. As the demand for seafood and other marine products continues to grow, the sustainable management of these resources becomes increasingly important. Marine technology can help us to achieve this by providing innovative solutions for sustainable fishing, aquaculture, and other forms of marine resource management.

In Ireland, claims are made that the island country "has the potential to be the “Silicon Valley” of the aquatech world". Ireland is at a very exciting stage when it comes to aquatech. There are currently 62 aquatech companies operating here, all using technology to enable sustainable seafood farming at a time when the sector is facing many challenges.”

Ireland’s growing expertise in the developing aquatech sector means it has the potential to become a global leader in the field, with Irish aquatech companies turning over €200m last year.

Over €15m has been invested in aquatic businesses, and over 200 high-tech jobs have been created in the sector over the last six years.

In conclusion, marine technology is a vast and rapidly evolving field encompassing a broad range of technologies and applications. As we continue to explore and exploit the potential of the oceans, marine technology will play an increasingly important role in ensuring the safe and sustainable use of these resources.
