Paradise won’t protect itself


The Great Barrier Reef is one of the most spectacular living networks on our planet.
Seeing it for yourself will leave you speechless.
So be curious.
Look beneath the surface.
Marvel at the intricate details of our natural world.
Now more than ever, the simplicity of getting outside and experiencing nature is important to us all.
It's these freedoms and connections that help us realise what it truly means to be alive.
And it forces us to comprehend the impact we, as humans, are having on the world around us.
Learning and understanding of its connectedness to us is the number one driver for innovative and creative change.

Early in 2020, we spent a week with marine biologist, Johnny Gaskell, who leads a team pioneering a reef restoration program in the Whitsunday Region - a mountainous archipelago made up of 74, mostly uninhabited, islands inside the Great Barrier Reef.
Alongside him, Australian marine biologist, Laura Wells, and South African surfer, Frank Solomon, explored the mind-blowing beauty of the Whitsundays and learned of the environmental challenges this region faces.

Johnny is a big advocate for people learning firsthand and encourages everyone to jump in the water; he believes curiosity gets people invested and motivates them to be a part of reef protection.
Seeing the restoration of the reef firsthand juxtaposed with the impact that plastics and pollution have on what seems a paradise, might just be the catalyst for change.

How a Chinese sailboat became a microcosm for Arctic geopolitics

From The Diplomat By Trym Eiterjord
 
A Chinese sailor’s attempted journey through the Arctic Ocean ran aground on disputed sovereignty complaints.
 
On June 30, Zhai Mo, a Chinese painter-turned-adventurer, set sail from Shanghai on what was supposed to be, in his own words, the first-ever non-stop circumnavigation of the Arctic Ocean.
Zhai, whose earlier nautical achievements include a two-year solo circumnavigation of the Earth, was now embarking on a four-month journey along the shores of the world’s northernmost ocean, ostensibly to bring attention to the effects of climate change in the Arctic.

Yet there was more to the northbound odyssey than the environment.
“This voyage will help implement the Belt and Road Initiative,” the China Daily declared as the modestly named Zhai Mo 1 departed Shanghai.

As climate change thaws open previously iced-over waterways in the circumpolar north, Beijing has begun using the term “Polar Silk Road” to refer to the Arctic Ocean and the various sea routes that crisscross it, including the Northern Sea Route along Russia’s northern coast, the Northwest Passage via Canada, and, pending further sea ice decline, a possible transpolar route cutting across the North Pole.
The Polar Silk Road, as with the Belt and Road Initiative more broadly, has become shorthand for the geoeconomic goals that Beijing endeavors to realize in the region, with shipping forming a key interest.

But as the Arctic sea ice continues to diminish and its waters become more navigable, disputes over the legal status of various channels and straits are re-surfacing.
And Beijing, which only a decade ago paid little attention to maritime affairs in the Arctic, has begun to take a more active interest in the governance of these northern waters with an eye toward securing access to Arctic sea routes.
These aspirations put the country at odds with the region’s coastal states.

Whether by accident or by design, Zhai’s polar peregrinations expose these tensions.

The geopolitical undertones of Zhai’s sailing were made more overt by the plethora of state-owned companies and government agencies that have lined up to sponsor and support the voyage.
Telecom major China Mobile is using the voyage as a branding opportunity, having partnered with Zhai to emblazon the state-owned company’s logo across the ship’s hull and sail.
Other state-owned sponsors include shipping giant COSCO, which started sending commercial voyages through the Northern Sea Route in 2013.
China Global Television Network (CGTN), the international division of CCTV, the country’s state-controlled broadcaster, is also heavily involved in Zhai’s voyage, hosting regular hour-long live streams featuring the captain discussing his day-to-day experiences navigating the Arctic.
Another sponsor, China Institution of Navigation, which recently began working more closely with the country’s polar research community and shipping industry in an effort to improve China’s polar seafaring capabilities, sent high-ranking representatives to Zhai Mo 1’s launch in Shanghai.

A month after setting sail, Zhai and his crew of two reached the Bering Strait, the Pacific gateway to the Arctic Ocean, to commence their polar circumnavigation.
They hung west toward the north coast of Russia, intending to sail via the Northeast Passage.
In early August, however, the crew encountered problems as they were nearing the Vil’kitskii Strait, located at the western entrance to the Northern Sea Route – part of the passage that Russia claims as internal waters.
Unable to produce the necessary paperwork to enter the strait, which is subject to Russian laws, the Russian Coast Guard denied the vessel passage.

In response, Zhai tried sailing north in an attempt to navigate around the strait but was stopped there as well, this time by heavy sea ice.
Blocked in, Zhai sent word to the ship’s owner in China, which, on August 9, filed an application with the Russian authorities.
Two days later, they granted Zhai permission to pass through the strait and continue his voyage westward.

Having overcome his brush with Russian maritime law enforcement in the Arctic, in mid-September, Zhai prepared to enter the Northwest Passage.
Much as how Russia exercises sovereignty over the Northern Sea Route, Canada claims the Northwest Passage as internal waters and mandates that foreign-flagged ships may only enter at their discretion.
Typically, foreign vessels have only needed to notify Canadian authorities before entering the Northwest Passage.
Last year, however, Ottawa issued a ban on pleasure crafts operating in its Arctic waters, including sailboats, to protect vulnerable communities in the area, which are largely Indigenous and lacking in medical facilities, from the spread of COVID-19.
The ban remains in effect today.
While international crafts “exercising their right of innocent passage” can be exempted, they are required to notify Canadian authorities at least 60 days before entering the country’s northern waters.

It seems, however, that Zhai did nothing of the sort.
The day before his planned entrance to the passage, the Chinese sailor proclaimed, “The international community views the passage as a sea route for international navigation.” Canada does not share this view: On September 16, Chinese media reported that Zhai had been “illegally stopped,” this time by the Canadian Coast Guard, as he was making his way from the North Atlantic Ocean into Lancaster Sound, the eastern opening of the Northwest Passage.

Transport Canada, the government agency responsible for regulating Canadian waterways, quickly refuted the claim that Zhai had been turned away when trying to enter the Northwest Passage, stating instead that Zhai had “not entered Canada’s Arctic Waters” and that they had been monitoring his vessel and had informed him of the ban on pleasure crafts.

Chinese state media judging the ban to be illegal is significant, as it would – assuming editorial decisions are sanctioned by Beijing – imply opposition to Canada’s sovereignty over the Northwest Passage.
If so, this would signal that China has grown bolder when it comes to asserting itself in the Arctic.

So far, Beijing has not taken a clear official position on the legal status of either the Northeast or the Northwest Passage.
In 2012, when the Chinese-flagged research icebreaker Xuelong completed its first voyage through the Northern Sea Route, state media noted that disagreement existed over whether certain segments of the route constituted “waters for international navigation.” 
Then, when asked at a press conference in 2016 about China’s position on the legal status of the Northwest Passage, a foreign ministry spokesperson gave a non-answer, noting, “Canada considered that the route crosses its waters, although some countries believed it was open to international navigation.” 
In its first Arctic policy, released in 2018, Beijing tip-toed around these issues again with a sweeping statement that it “respect[s] the sovereignty, sovereign rights, and jurisdiction enjoyed by the Arctic States.” 
The policy also stressed, however, that “the freedom of navigation enjoyed by all countries in accordance with the law [of the sea] and their rights to use the Arctic shipping routes should be ensured.”

A prerequisite for observer status at the Arctic Council, the region’s main inter-governmental forum, is recognition of Arctic states’ sovereign rights and jurisdiction in the region.
China has been an Arctic Council observer since 2013.
A break with the status quo would inevitably strain relations with Canada and Russia, as well as with the other Arctic Council member states.
China will “not overstep its position, nor will it be absent” from Arctic affairs, the 2018 policy paper states; but Beijing’s ability to balance what it sees as its rights in the Arctic with what its circumpolar counterparts consider diplomatically palatable is likely to become trickier if the country’s maritime activities in the region continue to grow.

Although China has yet to articulate an unequivocal position on these matters, the government’s views can be gleaned from not only the actions of Zhai Mo, but what its Arctic experts are saying, too.
While Chinese diplomats have largely toed the line of respecting Arctic states’ sovereignty, domestic academic discussions take a more belligerent stance.
In a follow-up article, CGTN interviewed Wang Zelin, an associate professor of political science at Northwest University of Politics and Law in Xi’an, who has published extensively on international law and Arctic shipping.
He, too, called the alleged actions by Canada illegal, asserting that “the Northwest Passage is an important sea route between the Atlantic and Pacific Oceans,” which should be considered a strait used for international navigation.

In many ways, Wang’s conclusion represents the position taken by most legal scholars in China studying the Arctic.
They tend to emphasize ensuring unfettered access to Arctic waters, by, as one recently published paper puts it, working toward “defining Arctic sea routes as international straits.”

China would not be alone in protesting the Canadian position.
The United States and the European Union similarly maintain that the Northwest Passage constitutes a strait used for international navigation.
Nor is this the first time a Chinese-flagged vessel has attempted to navigate the Northwest Passage.
In 2017, the research icebreaker Xuelong became the first Chinese-flagged vessel to navigate through the passage during the country’s eighth Arctic research expedition.
While that voyage prompted some critics to declare that the presence of a Chinese vessel was eroding Canada’s sovereignty over its waters, Xuelong’s transit was completed amicably and by the book.

It should be noted, however, that Sino-Canadian relations have taken a nosedive since then as a result of Huawei executive Meng Wanzhou’s detention in late 2018 and Beijing’s retaliatory imprisonment of two Canadian nationals.
In a separate op-ed to CGTN, Hong Nong, a political scientist and director of the Washington-based Institute for China-America Studies think tank, alluded to the two countries’ fraying relations.
She insisted that Zhai’s voyage did “not challenge Canada’s sovereignty or legal status over the Northwest Passage,” and that his voyage “should not be interpreted as carrying any political agenda.” Instead, she suggested that “given the current efforts by both states to resume or warm up bilateral relations,” Canadian authorities could exempt Zhai from the aforementioned ban as a gesture of diplomatic good will.
If the voyage did not initially bear an agenda, Hong seems set on giving it one.
 

Regardless of whether Canadian authorities stopped Zhai, the artist-cum-sailor has decided to re-route his voyage through the Panama Canal.
In a video posted to CGTN’s Twitter account on September 24, Zhai announced that his boat would now turn southward, sailing down the eastern coast of North America, through the Panama Canal, and across the Pacific, in order to return to Shanghai, turning what was originally a four-month voyage into an eight-month odyssey.
The detour ironically reveals the benefits of navigating through the much shorter, if icier, Northwest Passage.

One could chalk up Zhai’s incomplete circumpolar navigation to poor planning, regulatory ignorance, or a maritime maverick coming face-to-face with the bureaucratic realities of maritime law enforcement in the Arctic.
Or it could be something more deliberate.
After all, this would not be the first time that Zhai tried to make a geopolitical statement with one of his voyages.
When the territorial dispute over the Senkaku Islands flared up between China and Japan in 2012, Zhai dutifully set sail toward the islands.
There, he, and his crew of nine scattered miniature Chinese flags in the surrounding waters.

“It was rather more of a free and personal voyage,” Zhai, whose sailboat was escorted by the Chinese Coast Guard, told the Global Times at the time.
“A Chinese man who sails for sport can’t make that much trouble.
This approach to maintaining sovereignty is a lot more peaceful.”

ECDIS: is your system updated to the latest IHO Presentation Library?

 
 
From Pulse by Emiliano Caroletti, Senior Nautical Instructor, Master Mariner, CertHE (Open),MNI.
 
It has been already four years since the introduction of the new IHO S-52 Presentation Library, so this topic is well known among the insiders.
I wrote this article with one sole aim in mind, to give clear and simple explanations to a specific audience on a very specific topic.
The targeted audience are young Deck Officers, especially Deck Cadets and Third Mates.
The reason is that they will sooner or later experience a Port State Control inspection, so I tried to give them as much information as possible.
The topic is also quite interesting, one of the first questions asked by PSC officers refers to the ECDIS software update status, a function not used every day by the operators.
I believe that I kept the theory to an acceptable level.
All the resources are referenced with hyperlinks to official sources.
I hope that my effort will be appreciated by the “Captains of the future”.


“Is your ECDIS updated to the latest IHO Presentation Library?”
This is one of the most common question asked during a Port State Control inspection.
Why is it so important to have the latest version of the Presentation Library installed on board?
And what is the correct answer to the aforementioned question? 
 

The IHO Publication S-52 “Specifications for Chart Content and Display Aspects of ECDIS” provides specifications and guidance regarding Electronic Navigational Charts (ENC) updates and the display of symbols and colours on the ECDIS.
The Annex A of the S-52 is the Presentation Library, this document gives a full detail of colours, symbols and instructions on how ENC database should be displayed on the ECDIS.

In the example below, a cardinal buoy will be coded following the IHO S-57 standard and added to the ENC database.
The Presentation Library installed into the ECDIS will read the code for the cardinal buoy and will search the right symbol to be depicted on the ECDIS.
This process happens for all the objects, lines and areas encoded into the ENC database in real time and at any scale.
Amazing, isn’t it? 

 


In other words, the Presentation Library embedded into the ECDIS is in charge of transforming a series of coded objects and attributes compiled in the ENC database into objects, lines and areas displayed on the screen.
The Presentation Library also describes how chart updates are displayed and how alerts from the Look-ahead sector and Route Corridor must be visualised.
With an outdated version of the PL installed, the ECDIS is unable to correctly visualise the ENC database, with the result that some symbols and/or areas are not displayed at all.

As stated in the IMO MSC.1/Circ.1503 “ECDIS – GUIDANCE FOR GOOD PRACTICE”; “ECDIS that is not updated to the latest version of the IHO Standards may not meet the chart carriage requirements as set out in SOLAS regulation V/19.2.1.4.
Any ECDIS which is not upgraded to be compatible with the latest version of the IHO ENC Product Specification or the Presentation Library may be unable to correctly display the latest charted features.
Additionally, the appropriate alarms and indications may not be activated even though the features have been included in the ENC.” (IMO, 2017)

The last sentence is very important because highlight the fact that even if the ENC cell is updated to the latest Notice to Mariners this does not necessarily mean that ECDIS is able to correctly display the objects contained in the ENC database.
The current version of the IHO Presentation Library is the 4.0 issued by the IHO in 2014 and entered into force 1st September 2017, the new PL supersedes the old 3.4 version.

Why has the PresLib been updated?
 
Between 2011 and 2014 , the IHO was collecting feedback from mariners on display anomalies present in the system.
After 4 years of study, the IHO released the new PL 4.0 and as stated by the IHO; “To address the display anomalies and improve the ECDIS user experience the IHO issued S-52 Presentation Library edition 4.0 in September 2014.
One of the principal benefits of upgrading ECDIS systems to the latest IHO Presentation Library is the reduction in audible alarms, which will ease the issue of alarm fatigue on the bridge whilst maintaining safety at sea.
The introduction of an alert model based on the requirements in the IMO ECDIS Performance Standard will also harmonise ECDIS alarm and indication behaviour across different manufacturers systems.
A few new symbols have also been added to the IHO Presentation Library.
These symbols will identify features that require an indication highlight; the location of automatic ENC updates; and ENC features that have a temporal attribute.” (IHO, 2017).

The new symbols introduced in IHO Presentation Library edition 4.0 are shown below.
 


What is the impact on shipping companies and mariners?
 
A clear answer can be found in a document written in 2017 by the Dutch Ministry of Infrastructure and Environment; “From 31 August 2017, IHO Standards S-52 Edition 6.0 – Chart Content and Display Aspects, Presentation Library Edition 3.4 and Standard S-64 – Test Data Sets Ed. 2.0, are no longer valid for existing systems.
From 1 September 2017 ECDIS systems which do not fulfil hardware and software requirements, and subsequently cannot present ENC’s according to the latest IHO standards, cannot be considered as meeting the chart carriage requirements of SOLAS V reg. 19.2.1.4, nor as meeting the qualification of “up to date” nautical charts referred to in SOLAS V reg. 27.
It is the responsibility of the company and the master to ensure compliance with V/27 and the ensure that the ECDIS application software, and hardware if necessary, is updated before 31 August 2017.
All ECDIS on board, including those, which are not use for primary navigation, shall comply with the latest IHO standards”.

The new IHO ECDIS Presentation Library edition 4.0 clause 19.1 states: “The edition number of the PresLib installed must be available to the Mariner on request”.
This requirement is tested in the standard IEC 61174 edition 4 clause 5.5.1, Presentation library (S 52/Annex A, Part I/19.1) “The edition number of the PresLib installed shall be available to the Mariner on request”.

All Mariners must familiarise themselves with the function in their ECDIS that displays the edition number of the IHO Presentation Library, as this varies across ECDIS manufactures.
This function will be required when Port State Control officers want evidence that the ECDIS is up to date to the latest IHO standards.
MSC.1/Circ.1503 as amended: “Additionally, ECDIS software should be kept up to date such that it can display up-to-date electronic charts correctly according to the latest version of IHO’s chart content and display standards” (IMO, 2017).

There are several ways to access the information regarding the Presentation Library installed in the system.
Each manufacturer has its own way to do it, what all the ECDIS have in common is the possibility to display the ECDIS Chart 1 on the screen.
The ECDIS chart 1 is a legend of symbols used in ENCs and should be installed on all type approved ECDIS.Viewing ECDIS Chart 1, “Information about chart display (A, B)” within the ECDIS will only display the new symbols if the IHO Presentation Library edition 4.0 is installed.

The beacon and buoy features here below display the date dependent magenta ‘d’ symbol when the ECDIS date range is set between 01.04.2014 and 27.08.2014.
It will not be possible to view the new symbols if the ECDIS software has not been updated to use the S-52 Presentation Library Edition 4.0.


This is the method recommended by IHO for checking whether the ECDIS system can correctly display the new symbols.

There is no intention for the IHO to issue a check data set for IHO Presentation Library edition 4.0.

Here we have our answer: each type approved ECDIS is capable to display the ECDIS Chart 1, and if the system is updated to the latest Presentation Library the symbols highlighted in the red circles are displayed.
This is a small but very important piece of the "ECDIS puzzle", the PL is not just an obscure computer program running in the background.
These few Megabyte are controlling if, how and when cartographic information is displayed on the ECDIS, especially dangers and hazards to navigation, therefore the mariner must be aware of its function.

Where is Earth’s largest waterfall?

The world's largest waterfall is in the ocean

From NOAA

The world’s largest waterfall is in the ocean beneath the Denmark Strait. 

In the Denmark Strait, southward-flowing frigid water from the Nordic Seas meets warmer water from the Irminger Sea.
The cold, dense water quickly sinks below the warmer water and flows over the huge drop in the ocean floor, creating a downward flow estimated over 123 million cubic feet per second. 

Rivers flowing over Earth’s gorges create waterfalls that are natural wonders, drawing millions of visitors to their breathtaking beauty, grandeur, and power.
But no waterfall is larger or more powerful than those that lie beneath the ocean, cascading over immense cataracts hidden from our view. 
 
Localization with the GeoGarage platform (DGA nautical raster chart)

Indeed, the world’s largest waterfall lies beneath the Denmark Strait, which separates Iceland and Greenland.
At the bottom of the strait are a series of cataracts that begin 2,000 feet under the strait’s surface and plunge to a depth of 10,000 feet at the southern tip of Greenland—nearly a two-mile drop.

But how can there be waterfalls in the ocean?
It’s because cold water is denser than warm water, and in the Denmark Strait, southward-flowing frigid water from the Nordic Seas meets warmer water from the Irminger Sea.
The cold, dense water quickly sinks below the warmer water and flows over the huge drop in the ocean floor, creating a downward flow estimated at well over 123 million cubic feet per second.
Because it flows beneath the ocean surface, however, the massive turbulence of the Denmark Strait goes completely undetected without the aid of scientific instruments.

This infographic illustrates how a large underwater cataract (waterfall) naturally forms underneath the waves within the Denmark Strait.
A map in the upper right of the graphic shows the location of Denmark Strait, between Greenland and Iceland. Warmer surface waters flow northward.
These warmer waters gradually lose heat to the atmosphere and sink.
Denser, cold water flows southward in a deep current along the sea floor over an undersea ridge in the Strait.
The height of the Denmark Strait cataract is approximately 11,500 feet.
By comparison, the largest waterfall on land is 3,212 feet.
