#MarineWildlife - An Irish marine research vessel has returned from an Atlantic Ocean voyage with tales of exotic new wildlife in the depths southwest of Ireland.

As The Irish Times reports, remarkable finds such as two-century-old clams and oysters, an endangered sailfin roughshark, a massive sponge and a giant hydroid - a rare relation to jellyfish and coral - were among the marine wildlife recorded by researchers on the RV Celtic Explorer in the Whittard Canyon on the Irish Atlantic margin.

Dr Louise Allcock of NUI Galway, who led the Marine Institute team on the ocean survey, said it was "part of an ongoing effort to understand Ireland's deep-sea biodiversity".

In a similar process to that used by the group who made new marine discoveries at Rockall recently, the Marine Institute team used a submersible remotely operated vehicle (ROV) to collect images and samples from the ocean chasm that's twice as deep as the Grand Canyon.

Some of those samples may aid in antibacterial and pharmaceutical research, the team explained.

In other marine wildlife news, the Belfast Telegraph fears that "chilly seas" could be keeping basking sharks at bay from Northern Ireland's waters, as the first sighting of the year was recorded last month.

Reports from various sources indicate that water temperatures are 2 to 3 degrees lower than normal for this time of year, inhibiting the blooming of plankton that are the main source of food for the second-largest fish in the sea.

And the numbers say it all, with the Irish Whale and Dolphin Group (IWDG) confirming only 19 sightings of basking sharks around the island of Ireland as of the end of May this year, compared to 84 in the same period in 2012 - although more were spotted earlier this month off Malin Head, as the video below shows:

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.
