New initiatives needed to protect marine migration, says Irish scientist involved in global study
However, current targets on designating marine protected areas (MPAs) are not enough to halt biodiversity loss, and other measures will need to be taken, a study involving six Irish scientists showed.
Named MegaMove, the sharing of data by nearly 400 scientists from over 50 countries informed the UN-backed global research, which is published in the journal Science on the eve of UN World Oceans Day tomorrow.
Dr Mark Jessopp, one of six Irish-based scientists involved, all from University College Cork (UCC), said the study was the first of its type in terms of scale.
'The study's goal was to identify areas used by marine megafauna for important behaviours like foraging, resting or migratory corridors, and these areas and behaviours can only be found based on their tracked movement patterns,' he said.
We will need a range of initiatives, such as changing shipping lanes and restricting some types of commercial fishing gear
Dr Jessopp has expertise in the puffin, classified as endangered in Europe, which can fly vast distances from Ireland across the Atlantic in winter.
The epic migration makes the birds vulnerable to a range of impacts outside Irish waters, and the study highlights the vital role of international co-ordination.
Similar approaches could be taken to other marine megafauna frequenting Irish waters, such as whales and basking sharks, already protected here, and other seabirds, Dr Jessopp said.
The combined research, he added, 'outlines the most important locations for 30pc area protection for global marine megafauna species, ranking them based on the largest number of species using areas for important behaviours'.
'It shows that the EU target for designating 30pc of MPAs by 2030 is a good start, but we will need a range of other initiatives, such as changing shipping lanes, restricting use of some types of commercial fishing gear and restricting placement of offshore wind projects,' Dr Jessopp said.
MPAs for conservation of marine species and habitats cover 8pc of the world's oceans, which the UN High Seas Treaty wants to expand to 30pc.

The blue sharks we tracked from Cork migrated south into the Bay of Biscay … and as far as the Canary Islands
Dr Tom Doyle, also a contributor, said the study is important for Ireland in view of 'the fair share of large migratory species that use our waters'.
'For example, blue sharks migrate thousands of kilometres and can cross many different EEZs [exclusive economic zones]. The blue sharks we tracked from Cork migrated south into the Bay of Biscay, the Azores and as far as the coastal waters of Morocco and the Canary Islands,' Dr Doyle said.
'This presents a challenge for area- based conservation in terms of where to best place MPAs.
'Results from this study suggest that our animals spend most of their time in EEZs, so enhancing protection within areas of national jurisdiction and as part of a network of MPAs is one of the quickest ways to help our blue sharks and other species.'
The other UCC scientists involved in the international study were Professor John Quinn, Dr Ashley Bennison, Dr Michelle Cronin and Luke Harman.

Japanese lunar lander crashes while attempting touchdown on the Moon
A private lunar lander from Japan crashed while attempting a touchdown on Friday, the latest casualty in the commercial rush to the Moon. Tokyo-based company ispace declared the mission a failure several hours after communication was lost with the lander. Flight controllers scrambled to gain contact, but were met with only silence and said they were concluding the mission. Communications ceased less than two minutes before the spacecraft's scheduled landing on the Moon with a mini rover. Until then, the descent from lunar orbit seemed to be going well. People await the update on the private lunar lander's attempt to touch down on the Moon (Kyodo News via AP/PA) Takeshi Hakamada, ispace chief executive officer and founder, apologised to everyone who contributed to the mission, the second lunar strikeout for the company. Two years ago, the company's first moonshot ended in a crash landing, giving rise to the name Resilience for its successor lander. Resilience carried a rover with a shovel to gather lunar dirt as well as a Swedish artist's toy-size red house for placement on the Moon's dusty surface. Company officials said it was too soon to know whether the same problem doomed both missions. 'This is the second time that we were not able to land. So we really have to take it very seriously,' Mr Hakamada told reporters. He stressed the company would press ahead with more lunar missions. A preliminary analysis indicates the laser system for measuring the altitude did not work as planned and the lander descended too fast, officials said. 'Based on these circumstances, it is currently assumed that the lander likely performed a hard landing on the lunar surface,' the company said in a written statement. Long the province of governments, the Moon became a target of private outfits in 2019, with more flops than successes along the way. Takeshi Hakamada apologised for the mission's failure (Kyodo News via AP/PA) Launched in January from Florida on a long, roundabout journey, Resilience entered lunar orbit last month. It shared a SpaceX ride with Firefly Aerospace's Blue Ghost, which reached the Moon faster and became the first private entity to successfully land there in March. Another US company, Intuitive Machines, arrived at the Moon a few days after Firefly. But the tall, spindly lander face-planted in a crater near the south pole and was declared dead within hours. Resilience was targeting the top of the Moon, a less treacherous place than the shadowy bottom. The ispace team chose a flat area with few boulders in Mare Frigoris or Sea of Cold, a long and narrow region full of craters and ancient lava flows that stretches across the near side's northern tier. Plans had called for the 7.5ft Resilience to beam back pictures within hours and for the lander to lower the piggybacking rover onto the lunar surface this weekend. Made of carbon fibre-reinforced plastic with four wheels, ispace's European-built rover — named Tenacious — sported a high-definition camera to scout out the area and a shovel to scoop up some lunar dirt for Nasa. The rover was going to stick close to the lander, going in circles at a speed of less than one inch per second.
