==Wiki Education assignment: Introduction to Policy Analysis==
==Split from North Pacific Gyre==

I have split this article from [[North Pacific Gyre]]. See [[Talk:North Pacific Gyre]] for some discussion of this topic. -- [[User:Alan Liefting|Alan Liefting]]- (<small>[[User_talk:Alan_Liefting|talk]]</small>) - 22:53, 15 March 2008 (UTC)
:I took a look at the discussion and I'm not clear why one small article was split into two smaller articles. Can you explain why the article was split? Thanks. &mdash;[[User:Viriditas|Viriditas]] | [[User talk:Viriditas|Talk]] 14:48, 27 March 2008 (UTC)
::Well, it does seem like this one feature of the gyre is covered disproportionately, and both articles still have strong potential for growth. Seems fine to me to keep them separate, especially since this one will have a number of redirects and links on the garbage issue in particular. Perhaps this will free up the gyre article for more coverage of the oceanographic aspects. -- [[User:Beland|Beland]] ([[User talk:Beland|talk]]) 17:22, 27 March 2008 (UTC)
:::You are the third person to argue that the articles should remain separate. But, I sill don't see why they were split. Yes, you have given me a good ''what if'' scenario, explaining what you think they should ''become'', but I edit articles based on ''what is'' and I still don't understand why a short article was split into two shorter articles. The redirect issue is easily solved using inline section redirects. I admit that maybe I am not "getting it", but this does a disservice to the reader, forcing them to visit two pages instead of one to read about related content. I think the problem is that we have three editors taking a ''specialist'' POV, which is great when it is required, but in this case, we need a ''generalist'' approach. Ideally, the articles should be split when the size passes a certain threshold, and even then, summary style would be appropriate. The current split seems to go about the process backwards. Small, related topics are more accessible in ''one'' location, not two. &mdash;[[User:Viriditas|Viriditas]] | [[User talk:Viriditas|Talk]] 07:58, 29 March 2008 (UTC)
I agree with the above in that while their might be a reason to split the articles in the future, due to the small size of each currently, they should remain together so as to provide the reader with the full gambit of information rather than forcing them to visit both pages. An earlier poster argued that there is a disproportionate amount of information on the garbage aspect, but that doesn't mean that the garbage isnt the most important/prevalent issue and therefor should be included with the main article. <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/209.226.80.226|209.226.80.226]] ([[User talk:209.226.80.226|talk]]) 21:02, 9 April 2008 (UTC)</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
:I disagree with the proposal to merge, as the gyre and garbage patch are distinct subjects, and so the two articles should remain seperate. While the gyre article may short, the garbage patch one is not so. There is definitely capacity for expansion in both, as they are well studied phenomenon — [[User:Jrockley|Jack]] ([[User talk:Jrockley|talk]]) 01:00, 14 April 2008 (UTC)
*I agree that this article deserves an individual entry, but I will merge [[North Pacific Gyre]] to the main [[Gyre]] article, since it is suffucuenbtly succinct that it can accommodate the information. It seems to have split to allow this article to expand. Now that it is separate, we can merge back. Agreed? [[User:Eusebeus|Eusebeus]] ([[User talk:Eusebeus|talk]]) 16:52, 21 May 2008 (UTC)

== When and how was the Garbage Patch discovered? ==


This hatnote was removed as redundant today:
The article needs a section on "history of human understanding", and a documentation of any significant academic study or research into the Garbage Patch. — [[User:Jrockley|Jack]] ([[User talk:Jrockley|talk]]) 03:43, 24 April 2008 (UTC)
{{tqb|''"Plastic Trash Vortex", "Rubbish Vortex", "trash vortex", and "plastic vortex" redirect here. For the general topic of garbage collecting in gyres, see [[garbage patch]].''}}

[[Trash Isles]] also redirects here. Are these terms used solely for this particular patch, or should they just redirect to the general [[garbage patch]] article instead? [[User:Belbury|Belbury]] ([[User talk:Belbury|talk]]) 09:33, 20 November 2024 (UTC)
:According to National Geographic, the Patch was discovered in 1997 by Captain Charles Moore while sailing his 50-foot catamaran. The article indicates that the Patch has been known for two decades, but this is counter to what Nat Geo reports. Therefore, since the information in the article didn't have a citation about the discovery of the Patch, and the mentioned timeframe is counter to a reliable source, I have added the info from Nat Geo, and removed the two decade point. --[[User:Bentonia School|Bentonia School]] ([[User talk:Bentonia School|talk]]) 15:07, 16 July 2008 (UTC)

::In passing, I seem to remember the garbage patch, or something like it, being referenced in the 1992 novel ''[[Snow Crash]]''. I'm not sure that I buy the 1997 date. I'll see if I can find anything on the [[Web of Knowledge]]. Cheers, --[[User:Plumbago|Plumbago]] ([[User talk:Plumbago|talk]]) 11:05, 18 July 2008 (UTC)

::I couldn't find anything beyond the Moore ''et al.'' references which I now see are listed below. The Day (1988) government report cited below sounds promising, although I can't find an electronic copy of (it gets cited by Moore ''et al.'' though).

== Photograph & Scientific Data ==

And yet, after all this time, and all these headlines there is not one single verifiable photograph of this alleged mass of waste that is twice the size of Texas...how is this piece of folklore encyclopedia material?

[[Special:Contributions/194.75.171.33|194.75.171.33]] ([[User talk:194.75.171.33|talk]]) 11:13, 13 May 2008 (UTC)

:You want a photo? So go there with a GOOD underwater camera, it's international waters. But this is not whole bottles or sneakers floating on the surface. It's small crumbs and chips drifting ''below'' the surface. But I think the article's assertion that taking a photo is "impossible" is too rash. It should be very hard, but possible if you have a bit of luck with the lighting.

::Not according to this part of the article, it isn't: <blockquote>The existence of the garbage patch received wider public and scientific attention after it was documented in several articles written by Charles Moore, a California-based sea captain and ocean researcher. Moore, returning home through the North Pacific Gyre after competing in the Transpac sailing race, came upon an enormous stretch of floating debris.</blockquote> Is Moore lying or mistaken about this, or is there really "an enormous stretch of floating debris"?--[[Special:Contributions/65.189.54.153|65.189.54.153]] ([[User talk:65.189.54.153|talk]]) 16:09, 30 May 2009 (UTC)

:::Presumably lots. Of course, you have all sorts of traditional marine debris too. Floating underwater islets clustering around non-recaying ropes, fishernets and swimmers like so much seaweed. A long stretch of floating garbage is also what you see if a ship unscrupulously dumps its domestic waste overboard. Inside the gyre, stuff from all over the Pac collects, and the frequency and size of local concentrations of relatively undecayed stuff grows. Like, say, three football fields that look like a huge cargoliner or 5 full of assorted plastic debris went down. That is certainly large by human standards. But as such, the patch is large by ''Earth'' standards. The ''average'' concentration is low and the ''average'' mass of individual particles is low. So you're driving right through it, but on such a drive you have good odds to coma across a locale where the soup is thicker and more chunky.
:::Don't be expecting to get stuck in sme trashfield like ships in those old fancy drawings of the Sargasso Sea (which is basically the Atlantic little brother. Seaweed is thicker there, because coasts and the nutrient-rich Caribbean are close by, so the Sargasso Sea has always been naturally fertile and warmer). [[User:Dysmorodrepanis|Dysmorodrepanis]] ([[User talk:Dysmorodrepanis|talk]]) 20:37, 17 October 2009 (UTC)

:And if you have ever traveled across this part of the world, you'd know that it is not exactly trivial to get there in the first place. There is nothing of interest in this region except for marine biologists and geoscientists. Just a large expanse of ocean, devoid of land (which is the main reason this phenomenon exists in the first place). It's too far off the beaten track even for fishermen, and the climate is technically too damn close to a freakin' desert (see [[Horse latitudes]]) for any sane person's comfort. [[User:Dysmorodrepanis|Dysmorodrepanis]] ([[User talk:Dysmorodrepanis|talk]]) 22:50, 28 May 2008 (UTC)

::I think that the anon might be expecting a satellite photograph of it. Depending upon the abundance of waste items and their position in the water column (one presumes they float), I guess that they could change the appearance of the sea from space. Any ideas? --[[User:Plumbago|Plumbago]] ([[User talk:Plumbago|talk]]) 12:46, 18 July 2008 (UTC)

:::I am doubtful that satellite imagery would convey much. As the well-informed Dysmorodrepanis notes, this is a wide area of loosely suspended debris. I contacted the photographer of the image that you find typically associated with this (check Google Images and you'll see it), but on closer inspection, I am skeptical that the image is actually of the patch itself (i.e. just some garbage in the water). A final point, per my cleanup notes below, some work needs to be done on this article to make it more than ''"this piece of folklore"'' as described above. I was surprised how slight the scholarly literature appears to be. [[User:Eusebeus|Eusebeus]] ([[User talk:Eusebeus|talk]]) 13:31, 18 July 2008 (UTC)

::::I agree about the literature, although the Day (1988) reference that you found below would be interesting to see. Certainly, while it's pretty difficult to pick keywords that pull up anything on the "garbage patch", there seems to be a small quantity of work going on these days on waste plastics. My guess is that a real phenomenon ("trapping" of floating plastic waste in ocean gyres) has been massively hyped up by a positive feedback loop of media attention, till we get to fairly ridiculous statements suggesting that there's a plastic Texas floating out there. If I find any references that you haven't already tracked down, I'll add them here. It'd be nice to clear this one up, one way or the other. Not least because the ridiculousness of some of the statements about the patch has been picked up by bloggers, etc., looking for a stick to beat potentially genuine environmental concerns. Cheers, --[[User:Plumbago|Plumbago]] ([[User talk:Plumbago|talk]]) 13:59, 18 July 2008 (UTC)
*Hi Plumbago, do you have access to Science Direct? If you do, [http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V6N-44KKSGD-9&_user=458507&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000022002&_version=1&_urlVersion=0&_userid=458507&md5=fff8dd0852cf53cab1aed6f56c1e435e this article offers some great hard numbers]. Meanwhile, I'd like to check the accuracy of the "discovery" of the Garbage Patch, since this has been in the Scientific literature since the 1980s. In the event you don't have a subscription, the hard data are:

<blockquote>A total of 27 698 small pieces of plastic weighing 424 g were collected from the surface water at stations in the gyre, yielding a mean abundance of 3 34 271 pieces km2 and a mean mass of 5114 g/km2. Abundance ranged from 31 982 pieces km2 to 969 777 pieces/km2, and mass ranged from 64 to 30 169 g km2.

Plastic fragments accounted for the majority of the material collected in the smaller size categories. Thin plastic films, such as those used in sandwich bags, accounted for half of the abundance in the second largest size category, and pieces of line (polypropylene and monofilament) comprised the greatest fraction of the material collected in the largest size category.</blockquote>

More as I find it.

Here's the link to Day 1988.

http://swfsc.noaa.gov/publications/TM/SWFSC/NOAA-TM-NMFS-SWFSC-154_P247.PDF

Day postulated the existence of the patch

<blockquote>After entering the ocean, however, neuston plastic is redistributed by currents and winds. For example, plastic entering the ocean in Japan is moved eastward by the Subarctic Current (in Subarctic Water) and the Kuroshio (in Transitional Water, Kawai 1972; Favorite et al. 1976; Nagata et al. 1986). In this way, the plastic is transported from high-density areas to low-density areas. In addition to this eastward movement, Ekman stress from winds tends to move surface waters from the subarctic and the subtropics toward the Transitional Water mass as a whole (see Roden 1970: fig. 5). Because of the convergent nature of this Ekman flow, densities tend to be high in Transitional Water. In addition, the generally convergent nature of water in the North Pacific Central Gyre (Masuzawa 1972) should result in high densities there also. (Day, 1988, 261)</blockquote>

:Nice work [[User:Eusebeus|Eusebeus]]! And well done finding the report. It now seems more clear. I'll try to help you edit the article into shape next week (assuming you've not finished by then!). Incidentally, I do have Science Direct access, but I'm currently away from it - back next week. Cheers, --[[User:Plumbago|Plumbago]] ([[User talk:Plumbago|talk]]) 15:57, 18 July 2008 (UTC)

:Yeah, still think it would be useful to have at least a link to an actual picture of floating garbage. These ocean flow charts really don't mean much to skeptics, nor do random close-up pictures of garbage or dead animals on beaches somewhere. Even some of the links showing garbage brought up onto boats show pristine, deep blue oceans. [[User:Jd147703|Jd147703]] ([[User talk:Jd147703|talk]]) 14:10, 8 August 2008 (UTC)
::I am still in the process of rewriting this, but as you will see from the text, it would be a mistake to think of this as a largely visible see of plastic waste, the Moore description notwithstanding. See Plumbago's percipient comment above. I think we don't need to feed a misperception by including a false or misleading image. The EGP is what it is - a large concentration of photosynthesizing plastic debris concentrated in the upper water column. It is not a generally visible debris field. However, that said, I'll see what kinds of images can be obtained. [[User:Eusebeus|Eusebeus]] ([[User talk:Eusebeus|talk]]) 16:27, 8 August 2008 (UTC)
:::Thanks for that - that clears things up. Every media report I'd seen and the article here itself seemed to allude to a visible, "unpassable" mass. Any visuals we could get would be useful, though. [[User:Jd147703|Jd147703]] ([[User talk:Jd147703|talk]]) 16:10, 14 August 2008 (UTC)

== Where are the satellite map pictures? ==

A recent comment here that was deleted as "vandalism" asked a valid questions: why are there not satellite images of this thing?

I do not have any answer to that question. One would imagine that it would show up at least as a colour shift in the ocean.

(The poster actually asked for it on google earth. The reason it does not appear there, is simply that google earth hardly has any pictures at all of the sea. However, it could appear on other satellite or air pictures.) [[User:Mlewan|Mlewan]] ([[User talk:Mlewan|talk]]) 05:01, 12 October 2008 (UTC)

'''WHY THERE IS NO PICTURE'''<br>

<i>An Explanation from [[User:Eusebeus|Eusebeus]]</i><br>

As attentive readers will observe, the "garbage patch" is defined as a very high concentration of pelagic plastics in the upper part of the water column. I appreciate that at first reading, it seems as if this means a huge debris field floating around this remote corner of the Pacific. Instead, it refers to an area where there is '''unusually high concentration of plastic particulate'''. Since plastics break down to ever smaller polymers, this means that such concentrated particulate matter will not be visible from space, nor show up as a continuous debris field. [[User:Eusebeus|Eusebeus]] ([[User talk:Eusebeus|talk]]) 16:04, 12 October 2008 (UTC)

:If there are three pieces per square meter and they weigh an average of 2 milligrams each (or is it 5?) they are going to be nearly invisible even close up. It is only when you multiply by the area of the patch you get thousands of tonnes of plastic. --[[User:Rumping|Rumping]] ([[User talk:Rumping|talk]]) 02:11, 14 November 2008 (UTC)

:For anyone who is confused, consider this analogy: there are hundreds of thousands of asteroids between Mars and Jupiter, but most people would find it difficult to spot any without an expensive telescope. Likewise, you can't just look at Google Earth and dismiss this as a trumped up hoax.[[User:Nemokara|Nemokara]] ([[User talk:Nemokara|talk]]) 00:59, 13 September 2009 (UTC)

== What centripetal tendency? ==

*"As material circulates in the current, the [[Centripetal force|centripetal tendency]] gradually moves floating debris toward the center, trapping it in the circumscribed oceanic region."[http://en.wikipedia.org/enwiki/w/index.php?title=Great_Pacific_Garbage_Patch&oldid=247038029#Formation]

Well that's a non-explanation. I've never heard of "the centripetal tendency", so I clicked on it expecting to be taken to a definition of some physical mechanism in oceanic currents that draws surface water inward. Instead it links to [[Centripetal force]], which is unhelpful and probably inappropriate. [[User:Melchoir|Melchoir]] ([[User talk:Melchoir|talk]]) 01:42, 23 October 2008 (UTC)

:...sentence deleted. [[User:Melchoir|Melchoir]] ([[User talk:Melchoir|talk]]) 00:07, 27 October 2008 (UTC)

== A Plan of Attack ? ==
I would like to see the addition of some possible solutions <BR><P>

I think it would be possible to refit a Cargo ship with a conveyor <BR> system that skims the surface of the ocean pulling the plastic soup on <BR> to sorting belts where sea life can be diverted back to the sea and <BR> sort out the recyclables. these belts then lead to compactors that <BR> form the trash into blocks that can be loaded into Cargo containers. <BR> that later get off loaded at a friendly port where the recyclables <BR> will be shipped to the appropriate facility and the non recyclable is <BR> sent where it can be dealt with properly.

:Hi [[User:JWKTrucker|JWKTrucker]]. Until the plan you outline above becomes reality, or is described in [[WP:RS|reliable sources]], I'm afraid that this isn't the place for it. Sorry. --[[User:Plumbago|P<small>LUMBAGO</small>]] 14:26, 10 April 2009 (UTC)

== Redirecting from "The plastic continent"? ==

A lot of people identify this by "The Plastic Continent" or "Plastic Continent" so it might be pertinent to redirect those who search for that to this page. I'm not the most experienced editor so I don't know how to do that. If someone else either tell me or do themselves that would probably help a lot of people. Thanks.

:"Plastic continent" is definitely a misnomer, but I don't see many results for this phrase in Google News. [http://news.google.co.uk/archivesearch?um=1&ned=uk&hl=en&q=%22plastic+continent%22&cf=all] [[User:Dynablaster|Dynablaster]] ([[User talk:Dynablaster|talk]]) 13:11, 15 May 2009 (UTC)

==Clarifying the article==

As there is no visible 'garbage patch', isn't it better to make this explicit? Is there a reputable alternative name for this and similar regions?

I would also say the photo of the 'Laysan Albatros' is misleading, as it can easily be inferred to be part of the 'garbage patch', when it is not. Suggestion: delete the picture.

([[User:TresRoque|TresRoque]] ([[User talk:TresRoque|talk]]) 18:42, 19 June 2009 (UTC))

The introduction is hyperbole. An 'exceptionally' high level of plastic, which amounts to an average of three 5-milligram sized pieces of plastic per square metre. No doubt that is troublesome and ecologically damaging, but the introduction gives a non-scientific reader the impression of something thousands of times more severe. May I put the '3 x 5 milligram' fact into the introduction?
([[User:Kipwatson|Kipwatson]] ([[User talk:Kipwatson|talk]]) 01:13, 9 August 2009 (UTC)).

:It is also 20 times the normal density. That to me qualifies as 'exceptional'. But yes, it never hurts to be precise. [[User:MickMacNee|MickMacNee]] ([[User talk:MickMacNee|talk]]) 01:45, 9 August 2009 (UTC)

== Size and existence ==

It seems that the estimation of size as double Texas is dubious. Even the existence of the patch seems to come from articles that quote only Charles Moore. I am seeing references quoting lots of newspapers that all quote Moore. I am not biased. Personally, I think this thing probably exists, and is the size Moore estimates. I am just having trouble with the claims vs. the quantity of independent, corroborating sources.--[[User:Anna Frodesiak|Anna Frodesiak]] ([[User talk:Anna Frodesiak|talk]]) 01:49, 17 July 2009 (UTC)

:I agree with you that on this topic there is an excessive reliance on Moore, who is a one man band for promoting awareness of the patch. (But note that the Wikipedia article was probably the first public site to make the correct attribution to Day 1988.)

:However, if you note the references I have adduced above you will see that the claims made have been published in leading peer-reviewed journals, and so well-above the threshold for reliable sourcing. One other point: the size of the patch is rather arbitrary. What is the cut-off for elevated levels of plastic in the neuston? As you will see in my discussion with Plumbago, the range is enormous. Moreover, the idea that there is a continuous field of pelagic debris is also inaccurate; the area affected is determined by sampling, but that provides an average and doesn't mean that the debris is distributed evenly across the gyre.

::Fair enough. Sorry that I wasn't more thorough in fact checking before I commented. There still remains the great need for someone to actually get a photo. The article could sure use it. I think readers kind of see it as a Loch Ness Garbage Patch. I'll keep digging for info on this one. Heck, maybe some fishing vessel has reported it and it never made it to the press. Cheers.--[[User:Anna Frodesiak|Anna Frodesiak]] ([[User talk:Anna Frodesiak|talk]]) 14:00, 17 July 2009 (UTC)
:::As I have noted above but don't mind repeating, the issue of providing a photographic accompaniment is questionable. The problem here is really Ebbermeyer's poor choice of wording. A "garbage patch" implies something that can be seen. However, it refers to an unusually high level of suspended plastic particulate in the upper reaches of the water column. This is not going to be visible in any meaningful way, just as, say high levels of arsenic would not be visible. Some of the plastics are large, but the highly concentrated levels of particulate are principally derived from photodegraded plastics that are too small to be seen. So instead of thinking of it as a garbage patch, it should be conceived of as a contaminated area. [[User:Eusebeus|Eusebeus]] ([[User talk:Eusebeus|talk]]) 14:37, 17 July 2009 (UTC)
::::If you'd like to see some video evidence, [[VBS.tv]] (a subsidiary of ''[[Vice (magazine)|Vice]]'' magazine) put out a documentary a while ago: ''Toxic Garbage Island'' (www.vbs.tv/watch/toxic/garbage-island-1-of-3). That link leads to part 1 of 3; parts 2 and 3 are linked on the page.

== A trip to the patch? ==

I found this.

Circa June 10, 2009. A group of scientists and conservationists are planning a two-month trip to examine the gyre. Jim Dufour, of the Scripps Institution of Oceangraphy is advising the trip. [http://www.labnews.co.uk/laboratory_article.php/4612/2/journey-to-examine-swirling-plastic-vortex]

I am not quite clear on it. This is Moore and a bunch of scientists. There are several articles about this mostly talking about fish and how thrilling it is to pass the date line. I don't see much about the GPGP apart from phrases from old info.

The trip apparently has ended at their destination at the north end of the Hawaiian islands. <s>I thought the GPGP was to the south.</s> What gives?--[[User:Anna Frodesiak|Anna Frodesiak]] ([[User talk:Anna Frodesiak|talk]]) 14:25, 17 July 2009 (UTC)

: The date line runs north/south and is unrelated to the equator. Recent GPGP surveys have all been either ~1000 miles west of California or to the northwest of Hawaii.

: Charles Moore's site has [http://www.algalita.org/VoyageMaps.htm these maps] of voyage routes along with pop-up descriptions as you click on the sailboats. You'll see plastic findings all over the place. Day 39 of the 2009 trip is very cool. See day 14-15 of 2008 which mentions a "a visible river of trash floating in the ocean."

This hatnote was removed as redundant today:

"Plastic Trash Vortex", "Rubbish Vortex", "trash vortex", and "plastic vortex" redirect here. For the general topic of garbage collecting in gyres, see garbage patch.

Trash Isles also redirects here. Are these terms used solely for this particular patch, or should they just redirect to the general garbage patch article instead? Belbury (talk) 09:33, 20 November 2024 (UTC)[reply]
