What seabirds can tell us about the tide

November 29, 2018

Summary: Razorbill tag data revealed that, at night, these seabirds spent a lot of their time idle on the sea surface. ‘We saw this as an opportunity to (…) test if the birds might be drifting with the tidal current,’ says one of the researchers. It turns out they were, according to a new Ocean Science study that shows the potential of using seabirds to measure ocean currents.

When the UK’s Royal Society for the Protection of Birds (RSPB) set out to tag razorbills, their aim was to track their behaviour and movements along the coast of North Wales. The tag data revealed that, at night, these seabirds spent a lot of their time idle on the sea surface. “We saw this as an opportunity to re-use the data and test if the birds might be drifting with the tidal current,” says Matt Cooper, a Master of Oceanography graduate from Bangor University in Wales. It turns out they were, according to a new study led by Cooper that shows the potential of using seabirds to measure ocean currents. The results are published today in the European Geosciences Union journal Ocean Science.

Using seabirds to tell us about the tide could be especially useful for the marine renewable energy industry. Generating tidal energy requires detailed knowledge of current speeds. Scientists and engineers traditionally measure tides by using radar or deploying anchors and buoys with scientific instruments. However, these scouting methods are challenging and expensive. If tagged seabirds could provide tidal data over a large area, they could help identify sites that would be good sources of tidal energy.

Cooper’s supervisors at Bangor University knew of his interest in tidal energy and data collection, so they suggested he look into seabird data collected by the RSPB to see whether it would be possible to extract tidal information from it. A few years earlier, from 2011 to 2014, a RSPB team had fitted GPS tags on razorbills on Puffin Island, North Wales, to study their distribution and breeding and feeding behaviours. These black and white seabirds, similar to puffins and guillemots, only come ashore to breed. They spend most of their time at sea, foraging or resting on the ocean surface.

The data collected when the birds were sitting on the sea surface for hours on end were interesting in terms of bird behaviour, but the Bangor University researchers saw another potential use. “We took data that was discarded from the original study and applied it to test a hypothesis in a different area of research,” says Cooper. “As far as we are aware, this paper is the first to describe the use of tagged seabirds for measuring currents of any kind,” the researchers write in their Ocean Science study.

The non-invasive GPS tags on the razorbills recorded their position every 100 seconds. With a set of positions and a known time between each of them, the scientists could calculate the speed and direction of the birds’ movements. After the sun set, the birds spent long periods at rest on the sea surface, drifting passively with the current. “[At these times] their changing position would reflect the movement of water at the ocean’s surface,” Cooper explains.

With speeds of more than 1 metre per second, the average tidal currents in the area of the Irish Sea the researchers focused on are very fast, faster than a razorbill can paddle, but much slower than the speeds the birds reach when flying. This means the team could filter out the times when the birds were flying. In addition, the filtered data showed that, when the birds were drifting, the direction of movement changed at the times of low and high tide, when the currents in the area were expected to change from ebb to flow and vice-versa. Therefore, the team could be sure that they were tracking the speed and direction of sea currents rather than the birds’ independent movements.

Using seabirds to measure tidal currents has limitations. “We must remember that these birds are behaving naturally and we cannot determine where they go,” says Cooper. But the Ocean Science study shows there is potential for this inexpensive method to provide crucial tidal information over a wide area. By studying other tagged seabirds, we could learn more about our oceans, especially in more remote regions where it is challenging to collect oceanographic data.

Cooper also hopes the method can reduce the costs of generating tidal renewable energy, “which has been a barrier to the development of this much needed industry.”

A wave energy technology is being developed that could help generate low-cost electricity for thousands of houses. The device costs less than conventional designs, has fewer moving parts, and is made of durable materials. It is designed to be incorporated into existing ocean energy systems and can convert wave power into electricity: here.

Police face recognition software misidentifies over 2,000 people as ‘criminals’

German police tests face recognition software | DW English

25 August 2017

Authorities trial new surveillance cameras with facial recognition technology at a train station in Berlin. Supporters say the new system is needed to prevent future terrorist attacks. But not everyone agrees.

From the BBC:

2,000 wrongly matched with possible criminals at Champions League

4 May 2018

More than 2,000 people were wrongly identified as possible criminals by facial scanning technology at the 2017 Champions League final in Cardiff.

South Wales Police used the technology as about 170,000 people were in Cardiff for the Real Madrid v Juventus game.

But out of the 2,470 potential matches with custody pictures – 92% – or 2,297 were wrong … according to data on the force’s website. …

But civil liberties campaign group Big Brother Watch called for the system to be scrapped, adding it was “outrageous” that more than 2,000 at the event had been wrongly identified.

“Not only is real-time facial recognition a threat to civil liberties, it is a dangerously inaccurate policing tool”, said director Silkie Carlo.

“The tech misidentifies innocent members of the public at a terrifying rate, leading to intrusive police stops and citizens being treated as suspects.”

Misleading, incompetent and authoritarian: the [British] Home Office’s defence of facial recognition: here.

It looks like that British police software is as ‘reliable’ as the fraudulent software of Volkswagen and other car corporations mismeasuring exhaust pollution. And as dangerous to human rights as the ‘Palantir’ Big Brother software of United States Donald Trump-loving and women’s suffrage-hating billionaire Peter Thiel.
