One of humanity’s greatest achievements has been mastering routes across the world’s oceans.
Communities separated by thousands of miles have been brought into contact and religious ideas have spread across the waters, while artistic creativity has been spurred on by the experience of seeing the products of different civilizations.
Customs have been decisively altered by the movement of ships across the oceans.
No one drank tea in medieval Europe, but once contact had been made with the tea-drinking Chinese, tea became the obsession of millions of people from Sweden to the United States — tea is part of the founding history of the United States, as the Boston Tea Party reveals.


We tend to think that the opening of the oceans was the work of the great explorers, especially the 15th century pioneers who edged their way through uncharted waters to southern Africa, the Indian Ocean and the spice lands of the Indies.
These were sailors such as Christopher Columbus, who chanced upon unsuspected lands that blocked the expected sea route from Europe to China and Japan.
But while these men did give the Age of Discovery its name, they didn’t start the exploration of the world’s oceans — and there were also scores of merchants who followed in their wake, taking full advantage of new knowledge about the open ocean to develop trade links across the world that were the precursors of modern globalization.
These were the people who really mastered the oceans and brought the continents into contact.


Already around 2500 BC, merchants were setting out from what is now Iraq, the seat of the ancient Sumerian civilization, carrying silver ingots to India, which was the seat of another even more mysterious civilization, that of the Indus Valley.
En route, they acquired copper from Oman and brought precious objects such as carnelian and lapis lazuli from India.
Accumulating and re-investing profits, they were the first capitalists.
The Indian Ocean became one of the great channels of trade between nations.
Greek merchants from Egypt exploited the monsoon winds to ensure a swift passage to south India.


The Chinese emperors tended to discourage uncontrolled trade, though prohibitions often did more to provoke traders into finding ways around the rules.
Early compasses were used for feng shui, not navigation.
But in the 12th century AD, when the coasts of China were open to the world, Hangzhou was at the peak of its prosperity.
Later, Marco Polo would bear witness to this vigorous commercial life, with its use of paper money and its links to Java and beyond.
And in the open Pacific, hundreds of scattered islands from Hawaii to Easter Island were settled over many centuries — the Polynesians only reached New Zealand around AD 1300.
Even without written records, the Polynesians transmitted exact knowledge of how to sail these apparently boundless waters from generation to generation.

By 1500 AD, the Portuguese had begun to show interest in what the Atlantic might offer.
That interest had resulted in the settlement of uninhabited islands including Madeira, which began to export phenomenal quantities of sugar.
Portugal also founded the slave trade, bringing captives from West Africa to Europe and later to the Americas without consideration for their humanity

 When Spain and Portugal dominated the world
This map shows the Spanish and Portuguese empires at their height.
They didn't hold all of this territory concurrently, but they were most powerful from 1580 to 1640, when they were politically unified.
Portugal would later pick up more territory in Africa, not shown on the map.
We often forget that Spain controlled big parts of Europe, in Italy and the Netherlands.
In the Middle Ages, Spain and Portugal were so powerful that they signed a set of treaties literally dividing up the globe between them.
They became so rich so quickly that their trade with the Ottoman Empire, perhaps the other great imperial power of the time, filled the Ottoman economy with more gold than it could handle and plunged it economy into an inflationary crisis so severe that the empire never fully recovered.

When European sailors — from Portugal, Spain, Holland, England, Denmark and France — entered the Pacific and the Indian Ocean starting in the 16th century, they found a lively maritime world that they could never truly dominate.
They still depended on the resources and supply lines of the inhabitants of the lands they visited, even as they created routes across the entire globe that brought Chinese porcelain and silk from Manila through Mexico to Havana and then on to Spain, or through Macao and then on past southern Africa all the way to Europe.
A symbol of these global links was the porcelain produced in China bearing the words E PLURIBUS UNUM made specially for the American market.

Since then, the oceans have only continued to tie the world together — most dramatically when new routes were literally carved out, with the building of the Suez Canal in the 19th century and the opening of the Panama Canal in 1914.
The first goods to pass through the Panama Canal consisted of a cargo of tinned pineapples from Hawaii.
The Pacific and the Atlantic were more closely tied together than ever before.

 Americans have mostly come around to accept that, despite what our grade school teachers may have told us, Europeans did not "discover" America; the original arrivals had done that 15,000 years earlier.
But Europeans did discover lots of land that had never been before seen by human eyes.
You can, embedded in this map, see successive waves of European exploration: first the Portuguese, then the Spanish, then the British and much later the Americans.
The map's creator, the always-insightful Bill Rankin, writes, "this map particularly underscores the maritime expertise of Pacific Islanders.
Unlike the islands of the Atlantic and Indian Oceans, nearly all of the Pacific was settled by the 14th century."

In the 21st century, however, new factors have changed entirely the way goods are carried across the seas, even though over 90% of world trade is carried on ships.
Containerization means that goods can be loaded in Chicago and unloaded in Warsaw without having to be unloaded at ports.
The great port cities of the world have been replaced by automated docks full of gantries and cranes.
Container ships carry many thousands of containers.

Business is conducted on a scale that utterly dwarfs that of even 20 years ago, transforming a familiar world.
And yet, through trade and cultural exchange, the seas continue to connect even the most distant lands.

Typhoon, Cyclone or Hurricane? Different names for the same storms

Powerful tropical storms occur all around the world, but what they’re called depends on where they form.

When a tropical storm pummeled Japan on Saturday with gusts of up to 135 miles per hour, forcing millions to evacuate their homes, it was called Typhoon Hagibis.
But the storm that carved a path of destruction across the Bahamas in September was Hurricane Dorian.
And when the most powerful storm to hit Bangladesh in years destroyed thousands of homes in May, it was called Cyclone Fani.

What is the difference between a typhoon, a hurricane and a cyclone?
It comes down only to the storm’s location.

All three are tropical cyclones — circular storms that form over warm waters with very low air pressure at the center, and winds greater than 74 miles an hour.
But different terms are used for such storms in different parts of the world.

The word “hurricane” is used for the storms that form in the North Atlantic, the northeastern Pacific, the Caribbean Sea or the Gulf of Mexico.
Typhoons develop in the northwestern Pacific and usually threaten Asia.

The international date line serves as the Pacific Ocean’s dividing marker, so when a hurricane crosses it from east to west, it becomes a typhoon instead, and vice versa.

The same kinds of storms in the Southern Hemisphere are easier to keep straight.

In the southern Indian Ocean or the South Pacific, they are called tropical cyclones or severe tropical cyclones.
In the Bay of Bengal or Arabian Sea, both in the northern Indian Ocean, they are simply called cyclones.

A season for every storm

In addition to having different names, hurricanes, typhoons and cyclones also have different seasons.
The Atlantic hurricane season officially runs from June 1 to Nov. 30.
The Pacific season starts slightly earlier.
Typhoons can form year round, but are most common from May to October.
The next cyclone season in the South Pacific will begin on Nov. 1 and end on April 30, 2020.

In the southern Indian Ocean, the season begins two weeks later and ends at the same time, except in the island nations of Mauritius and the Seychelles, where it extends to May 15.
Cyclones in the northern Indian Ocean have no official season, but tend to be concentrated from May to November.

What are hurricanes, typhoons and tropical cyclones and how do they form?
James Chubb at MetOffice explains how we classify the different storms and how they are formed.

Whatever they are called, tropical cyclones generally become weaker after they hit land, since they draw their energy from water evaporating from the oceans below them.
But they can travel quite far inland before they dissipate, wreaking havoc through wind damage, torrential rains and flooding.

Storms whose winds are not quite strong enough to qualify as tropical cyclones are called tropical storms if their sustained winds are 39 to 73 miles an hour, or tropical depressions (a reference to the low pressure at their core) below that range.

Tropical cyclones around the world are named according to a listmaintained by the World Meteorological Organization.
The names of the deadliest storms, like Typhoon Haiyan or Hurricane Katrina, are retired.

Grading a storm’s intensity

Hurricanes are rated in categories from 1 to 5 on the Saffir-Simpson scale, which is based on sustained wind speed.
According to the National Hurricane Center, storms in Category 3 or higher, which have wind speeds of at least 111 miles per hour, “are considered major hurricanes because of their potential for significant loss of life and damage.”

 Super Typhoon Hagibis. 
Earth's power & beauty on display.

Typhoons are monitored by the Japan Meteorological Agency, which also rates them by sustained wind speed.
It uses three classifications: “typhoon,” “very strong typhoon” or “violent typhoon.”

Powerful Typhoon Hagibis brings strong waves to the southern tip of Japan's Izu Peninsula.
It is forecast to crash into land in central or eastern Japan early Saturday evening, packing maximum gusts of 216 kilometres per hour (134 miles per hour), Japan's Meteorological Agency (JMA) said.

The super Typhoon Hagibis, now approaching Japan, is the 4th category 5 storm of 2019.
In the Pacific there was Typhoon Wutip, while in the Atlantic there was hurricane Dorian and Lorenzo.
The above animation shows the movement of Typhoon Hagibis using the Copernicus Marine Service product “Global Ocean Waves Analysis and Forecast updated Daily” significant wave height (in meters) from October 8th-14th, 2019.
Our forecast up to October 14th predicts up to 15 metre significant wave heights starting around October 10th, and these wave trains are expected to hit the southwestern coast of Japan on the 12th of October.
The significant wave height is the average height of the highest one-third of all waves. Hence, maximum wave height could be 1.5 to 2 times higher.
According to the Meteo France waves model team, that works on this Copernicus Marine Service product, wave height is generally predicted with good confidence for extreme weather events within wave models.

The Joint Typhoon Warning Center, a United States military command in Pearl Harbor, Hawaii, also issues storm advisories using the designations “tropical depression,” “tropical storm,” “typhoon” and “super typhoon.”

Cyclones in the Indian Ocean are classified according to two intensity scales, depending on where they are, with terms like “very intense tropical cyclone” and “super cyclonic storm.”
Australia rates cyclones much the way North America rates hurricanes, in categories from 1 to 5.

As violent as they are, these storms help to regulate the global climate, by moving heat energy away from the tropics and toward the poles.

Naming the storms

Storm terminology has been highly influenced by the histories and cultural interactions of different regions.

“Hurricane” appeared in English in the 16th century as an adaptation of the Spanish word “huracán.” “Typhoon” is variously described as coming from Arabic (“tafa”) or Chinese (“taifeng”), or perhaps both.
“Cyclone” was coined in the late 18th century by a British official in India, from the Greek for “moving in a circle.”

But a storm by any other name should still be taken seriously.

Fishpeople

PATAGONIA | FISHPEOPLE TRAILER from Bimarian Films
To some, the ocean is a fearsome and dangerous place.
But to others, it’s a limitless world of fun, freedom and opportunity where life can be lived to the full.
A new documentary presented by Patagonia and directed by Keith Malloy, FISHPEOPLE tells the stories of a unique cast of characters who have dedicated their lives to the sea.
From surfers and spearfishers to a former coal miner and a group of at-risk kids in San Francisco, it’s a film about the transformative effects of time spent in the ocean—and how we can leave our limitations behind to find deeper meaning in the saltwater wilderness that lies just beyond the shore.

Mocean


I love filming in the ocean more than anything, its not just a job, its a passion.
And sometimes its nice just to document waves without surfers riding them.
The feeling of jumping off the rocks in the dark by myself just to capture the very first rays of light hitting the ocean without another sole in sight is unexplainable, its one of the most amazing feelings ever, its like my own personal therapy.
And to realise that you're the only person on this planet that got to witness these rare moments of absolute beauty as they happen is a really special feeling.
And now im excited to share my experiences with you through my latest passion project "MOCEAN".

Trawler 14 times the size of UK fishing boats is plundering fish from British waters before Brexit

From The Telegraph by Steve Bird and Helena Horton 

A super trawler 14 times the size of UK fishing boats is plundering thousands of tonnes of fish from British waters before Brexit, when the Government will be able to kick the vessel out.

The 6,200 tonne Lithuanian-registered Margiris vessel was boarded by Government officials on Wednesday and found to be operating legally under European laws.

However, environmentalists fear it could be endangering short beaked common dolphins and bluefin tuna.
The ship - described as a vast floating fishing factory which can net and process 250 tonnes of fish each day - has been the target of a series of campaigns culminating in it being banned from Australian waters in 2013.

On Friday night it was 14 miles off the Sussex coastline having spent one week fishing in British waters.



While it is fishing mackerel to be sold to Africa, it is believed to be operating in breedings waters for sea bass, which is already overfished.
The ship, which is 465ft long with a net 1,950ft in length and 650ft wide, dwarfs most UK fishing boats.



Under the common fisheries policy set out by the European Commission, each EU country is given a quota of fish it can catch in European waters.
Each country then divides that quota between vessels, allocating set catch sizes along with documentation in the event of an inspection.
A spokesman for the Marine Management Organisation, the government agency responsible for enforcing fishing regulations in UK waters, said it boarded the boat on Wednesday, adding: “No infringements of fishing regulations were found.”

The Margiris, part of a larger ‘freezer fleet’, is owned by the Dutch company Parlevliet & Van der Plas which has 6,000 employees and offices around the world.
A company spokesman said it was behaving perfectly legally in “European waters”, denied its fishing techniques threatened endangered species and had trawled in the area for the last 30 years.
He added: “We fish until Brexit has happened - God knows when that is. But, we always respect the law.”

In the event of Britain leaving the European Union, the UK will have greater control over fishing in its waters.
A government source said: “On October 31 we will become an independent coastal state. This means that for the first time in more than 40 years, we will be able to decide who can fish in our waters and on what terms.”
She added those new powers will apply 200 nautical miles off the British coast, or the median line between our shores and those of any neighbouring country.
“Any access to UK waters will be a matter for negotiation,” she said.

Greenpeace protesters say they confronted the Margiris - previously known as Abel Tasman - in West Africa in March 2012 and in the Netherlands and Australia in 2013.
Its application to fish in Australian waters was rejected.



Chris Thorne, an oceans campaigner at Greenpeace, said: “Super trawlers are floating fish factories that can process hundreds of tonnes of fish every day.
“They are responsible for much of the over exploitation of our oceans that is decimating fish stocks, destroying marine ecosystems and ruining the livelihoods of inshore fishermen who fish sustainably and are the backbone of many coastal communities.”

A spokesman for the Blue Planet Society said super trawlers have the equivalent capacity of a dozen small-scale fishing vessels.
"Local, smaller fishing boats have to return to port to offload the fish prior to processing.
"We think the super trawler Margiris is targeting horse mackerel and pilchards off Sussex. This will put them in contact with short-beaked common dolphins, endangered bluefin tuna and overfished sea bass."

A European Commission official said: “The Commission is aware of concerns among non-governmental organisations concerning the activity of large trawlers.
“All vessels operating in EU waters, large and small, have to abide by the rules and this is controlled by the Member States' inspection and control services. It is a priority that all Union vessels comply with the legislation in force.”
He added that the Commission requires “concrete facts” regarding any “suspicion” a vessels infringes fishing rules.
