The Irish-led scientific expedition aboard the RV Celtic Explorer has discovered a previously uncharted field of hydrothermal vents along the Mid-Atlantic Ridge.
As previously reported on Afloat.ie, the team includes geochemists, marine biologists, marine geologists, marine geneticists and technicians from Ireland and the UK as well as a three-person TV crew from National Geographic filming for a documentary series to be broadcast next year.
The mission, led by Dr Andy Wheeler of University College Cork, returned to Cork last Thursday from an investigation 3,000 metres below the sea surface using their Remotely Operated Vehicle (ROV) Holland 1 at the first hydrothermal vent field to be explored north of the Azores.
Hydrothermal vents, which spew mineral-rich seawater heated to boiling point by volcanic rock in the Earth’s crust below, are home to a rich variety of marine life that thrives in complete darkness on bacteria fed by chemicals.
“On the first dive, we found the edge of the vent field within two hours of arriving on the seafloor, ” said Dr Wheeler. “Often the search for vents takes much longer, and our success is a testament to the hard work and skill of everyone on board.”
The field has been named the Moytirra Vent Field, after a battlefield from Irish mythology that means ‘Plain of the Pillars’.
“In comparison with other vent fields, Moytirra contains some monstrous chimneys and is in an unusual setting at the bottom of a cliff - a real beauty,” said Patrick Collins rom NUI Galway’s Ryan Institute.
His colleague John Copley of the University of Southhampton added: “Using the ROV’s high-definition video camera, we’ve watched unusual orange-bodied shrimp crawling around the chimneys, among clusters of tiny green limpets.
“Elsewhere there are writhing scale-worms, swirling mats of bacteria and eel-like fish – a riot of life in this unlikely haven on the ocean floor.”
Speaking from the RV Celtic Explorer in Cork, Marine Minister Simon Coveney hailed the “exciting new discovery”.
“Ireland is positioning itself as a centre for marine research from a European and international perspective and this work should be supported and welcomed,” he said.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
