#Rescue - The Irish Coast Guard and the RNLI were among the emergency services putting some new communication technology to the test last month.

As Phys.org reports, the emergency exercise in Malahide Estuary was designed to test the effectiveness of REACT, or Resource for Emergency services to Access Command and control data using satellite and hybrid Technologies.

The system, funded by the European Space Agency (ESA), employs satellite, mobile and other communications systems to maintain a constant open channel between different response services, even if one network goes down during a crisis.

Rescue teams in the field can also remain in two-way multimedia contact with co-ordinators in the control room to ensure the right people are where they need to be as quickly as possible.

Ritchie Hedderman, head of operations at the Dublin Fire Brigade, which also took part in the exercise, said: "In the event of a major emergency, secure and reliable communications are vital to the emergency services.

"I feel that the satellite communications in time will prove to be the primary and preferred means for communicating as it can supply voice, video and data back to regional and national control centres where strategic commanders can assess situation on the ground and provide the back up resources in order that a successful conclusion to the emergency can be obtained."

Communiations on the ocean could be vastly improved by a surprising method straight out of the sci-fi books - antennas made out of seawater (SEE VIDEO BELOW).

The US Navy is already engineering a revolutionary scheme to replace its bulky warship communications arrays with antennas composed of jets of seawater shot through electromagnetic hoops.

The salt in the water is the key component that allows the water jet to conduct electronagnetic signals just like a standard metal antenna. Frequency adjustments can be easily made by controlling the height and width of the water stream.

Popular Science speculates that the antennas could serve as compact emergency antennas for civilian watercraft or communication systems on offshore oil rigs.

Galway Port & Harbour

Galway Bay is a large bay on the west coast of Ireland, between County Galway in the province of Connacht to the north and the Burren in County Clare in the province of Munster to the south. Galway city and port is located on the northeast side of the bay. The bay is about 50 kilometres (31 miles) long and from 10 kilometres (6.2 miles) to 30 kilometres (19 miles) in breadth.

The Aran Islands are to the west across the entrance and there are numerous small islands within the bay.

Galway Port FAQs

Galway was founded in the 13th century by the de Burgo family, and became an important seaport with sailing ships bearing wine imports and exports of fish, hides and wool.

Not as old as previously thought. Galway bay was once a series of lagoons, known as Loch Lurgan, plied by people in log canoes. Ancient tree stumps exposed by storms in 2010 have been dated back about 7,500 years.

It is about 660,000 tonnes as it is a tidal port.

The dock gates open approximately two hours before high water and close at high water subject to ship movements on each tide.

The typical ship sizes are in the region of 4,000 to 6,000 tonnes

Turbines for about 14 wind projects have been imported in recent years, but the tonnage of these cargoes is light. A European industry report calculates that each turbine generates €10 million in locally generated revenue during construction and logistics/transport.

Yes, Iceland has selected Galway as European landing location for international telecommunications cables. Farice, a company wholly owned by the Icelandic Government, currently owns and operates two submarine cables linking Iceland to Northern Europe.

It is "very much a live project", Harbourmaster Capt Sheridan says, and the Port of Galway board is "awaiting the outcome of a Bord Pleanála determination", he says.

90% of the scrap steel is exported to Spain with the balance being shipped to Portugal. Since the pandemic, scrap steel is shipped to the Liverpool where it is either transhipped to larger ships bound for China.

It might look like silage, but in fact, its bales domestic and municipal waste, exported to Denmark where the waste is incinerated, and the heat is used in district heating of homes and schools. It is called RDF or Refuse Derived Fuel and has been exported out of Galway since 2013.

The new ferry is arriving at Galway Bay onboard the cargo ship SVENJA. The vessel is currently on passage to Belem, Brazil before making her way across the Atlantic to Galway.

Two Volvo round world races have selected Galway for the prestigious yacht race route. Some 10,000 people welcomed the boats in during its first stopover in 2009, when a festival was marked by stunning weather. It was also selected for the race finish in 2012. The Volvo has changed its name and is now known as the "Ocean Race". Capt Sheridan says that once port expansion and the re-urbanisation of the docklands is complete, the port will welcome the "ocean race, Clipper race, Tall Ships race, Small Ships Regatta and maybe the America's Cup right into the city centre...".

The pandemic was the reason why Seafest did not go ahead in Cork in 2020. Galway will welcome Seafest back after it calls to Waterford and Limerick, thus having been to all the Port cities.
