Government is being asked to prioritise money for military radar equipment, including primary radar, RTE News reports.

The Minister for Defence is expected to recommend a major increase in defence spending at the Cabinet meeting later today, describing it as the "biggest Government decision on the Defence Forces in living memory ... and one of the biggest things I have ever done in politics".

Simon Coveney will update the Government on how to proceed with the recommendations made by the Commission on the Future of the Defence Forces.

The minister will ask colleagues to increase defence force spending from the current €1.1 billion annually to €1.5 billlion by 2028.

This is the recommendation for what was termed "level two ambition" in the commission's report.

The commission had called for this target to be achieved by 2030, but Mr Coveney is aiming to have the funding in place two years earlier.

A team of scientists in France are ‘recruiting’ albatrosses to monitor fishing fleets in the ocean for illegal activity.

Smithsonian Magazine reports on the findings of a new study detailing efforts to tag the “sentinels of the sea” with tiny GPS trackers. These can detect short-range radar emissions from trawlers that may be acting suspiciously.

The team at CNRS, the French National Centre for Scientific Research, chose albatrosses to carry the devices as their extraordinary range at sea often exceeds that of aircraft and even some satellites in the most remote regions — and they tend to be attracted to fishing vessels as a food source.

In one six-month study of the Indian Ocean, researchers found that more than a quarter of fishing vessels detected at sea by the birds were not trackable on AIS — suggesting illegal fishing was afoot.

A new radar system in Galway Bay could help predict extreme weather events more accurately, The Irish Times reports.
Scientists at NUI Galway's Ryan Institute, in collaboration with the IBM Smarter Cities Technology Centre in Dublin, have installed the system on the shoreline in Galway Bay.
The system - the first of its kind in North Atlantic Europe - consists of two antennae, on Mutton Island and Spiddal, which scan the surface of the bay every half hour.
It then sends high-resolutions maps of surface currents and details of wave height and direction directly to the scientists' base at the NUIG campus.
The data is used, along with meteorological data, to develop models for forecasing marine conditions from tidal currents to storm surges - common on the challenging coastline around Galway Bay and the Aran Islands.
Moreover, the system is set to benefit the local community and beyond as the data, when completed, will be made freely available.
Silicon Republic says that the Galway Bay Coastal Observing System (GalCOS) could be used by sailors, fishermen and tourists to more accurately assess conditions in the area.
It could also be of use to local authorities in terms of providing details on the best time to release effluent while minimising environmental damage.
“This type of predictive modelling is critical to our Smarter Cities agenda," said IBM's Dr Lisa Amini, "and the findings can be widely applied to protect coastal cities and their environments."

The Star keelboat is a 6.9 metres (23 ft) one-design racing keelboat for two people designed by Francis Sweisguth in 1910.

The Star was an Olympic keelboat class from 1932 through to 2012, the last year keelboats appeared at the Summer Olympics at which Ireland's representatives were Peter O'Leary and David Burrows.

Ireland has performed well in the class internationally thanks to some Olympic campaigns including a bronze medal at the Star World Championships in 2000, won by Mark Mansfield and David O'Brien.

The boat is sloop-rigged, with a mainsail larger in proportional size than any other boat of its length. Unlike most modern racing boats, it does not use a spinnaker when sailing downwind. Instead, when running downwind a whisker pole is used to hold the jib out to windward for correct wind flow.

Early Stars were built from wood, but modern boats are of fibreglass and carbon construction.

The boat must weigh at least 671 kg (1,479 lb) with a maximum total sail area of 26.5 m2 (285 sq ft).

The Star class pioneered an unusual circular boom vang track, which allows the vang to effectively hold the boom down even when the boom is turned far outboard on a downwind run.

Another notable aspect of Star sailing is the extreme hiking position adopted by the crew and at times the helmsman, who normally use a harness to help hang low off the windward side of the boat with only their lower legs inside.
