In the 1940s, the tide was the most powerful wave in the ocean and in fact the tide at one point, measured 1.5 metres per second, was so powerful it could flip an entire boat over.

But in the 1950s, as the tide gradually receded, scientists noticed that the tide became smaller and smaller.

What started as a small, slow tide became a bigger, faster tide.

By the 1970s, tide gauges started to record the tide speed and depth, which revealed the tidal changes that were occurring, said Dr. Anne Ritchie, a tidal scientist at the University of British Columbia.

Now, the world’s oceans have been measuring the tides and tidal effects for decades.

When the tide is at its most powerful, a huge wave, called a super tide, can move at over 10 metres per minute.

But when the tide starts to recede, the waves are much slower and a very small wave called a tide trough is formed.

The tide troughs can reach hundreds of metres in length, so a tide gauge cannot always be used to predict when the tides will begin to recode.

That’s why the Australian Government is using a tide measure called the tide gauge to help predict when it will be safe to return to the sea, Ritchie said.

The Australia-France Treaty, signed in 1979, requires the international community to monitor and count the tides to determine whether any changes to the Earth’s oceans are occurring.

That treaty requires that any tide measurement in the Northern Hemisphere be made on land, not at sea, so scientists in the region can be more accurate.

While the Australian government has been using tide gaugers to monitor the changes to sea levels, they have been unable to keep up with the rate of sea level rise in the world, said Ritchie.

The World Wide Web has made it easier to get data about the tides.

“The World Wide Internet is the best place to find out about the change in tide, because there are lots of places that have these kinds of instruments, which are very powerful and accurate,” she said.

A lot of scientists say it is more likely that the world will see an increase in the frequency of extreme weather events such as floods, fires, tornadoes, and earthquakes, than a decrease.

“In the past, when there was more of an expectation of these kinds event to happen, then it’s usually more severe than it has been,” Ritchie explained.

“We’ve seen this in the U.S. as well, where in the last decade we’ve seen a lot of severe weather.

That has not been the case for the past 100 years.”

She also points to the increase in sea level over the past 150 years as an indication that the oceans are not doing a good job of absorbing the energy from greenhouse gases.

“It’s not like the oceans were just sitting there and doing nothing,” Racey said.

“That’s not happening.”

The ocean’s oceans do absorb about one per cent of the energy released into the atmosphere.

But they’re still the source of about three per cent that contributes to global warming.

Scientists say the oceans should not be treated as if they were a static entity.

“They are not a static body,” Ritts said.

When there is a change in the energy balance, the oceans have to adjust, Ritt said.

And there’s more to climate change than just sea level.

“This is about how much energy we’re emitting into the air,” she added.

“There are so many other things that are affecting the oceans.”
