PIP THE PLOVER VARIES HER DIET…

Hi guys, that’s me, Pip, in the picture above. I live in North America in the summer. That’s where I was born. I fly down south to somewhere warm for the winter. Like many migratory humans, my chosen place is the Bahamas. It’s got some great empty, safe beaches and the weather is (mostly) lovely. Unless a Big Wind happens. The tide-line is cram-full of meat-strings (these would be worms. Ed). There are great patches of weed larder to work through. It suits me very well, just like lots of other shore birds. It’s why some of us return every year.

I’ve just got one point to raise, if you wouldn’t mind. There’s a mass of plastic (and other) crap out there on the beaches. It washes in on every tide. I know it isn’t Bahamian crap, but has come from many miles away. But Mr Harbour has done some work with my portrait to identify what’s in the seaweed I’m feeding on that might be harmful. He enhanced it and picked out just the things he’s certain shouldn’t be there. All the blue bits, for a start. And who knows what else is under the weed that I can’t even see to avoid. The shoreline and the wrack line is my dining area. I might easily eat some of the small bits by mistake. I think I must do that quite often. That would be bad – too much plastic crap and I’ll be ill. Or die. There are only about 8000 of us in the whole big wide world. If 80 of us die from plastic ingestion, that’s one per cent. The loss has to be made up next breeding season before we can even begin to increase our population. 

Just sayin!

WORLD OCEANS DAY 2016: “STASH THE TRASH”

WORLD OCEANS DAY 2016: “STASH THE TRASH”

Today the NOAA and other worldwide ocean guardian organisations are celebrating World Oceans Day. Looking at the websites and FB pages, one message is clear: People Are Rubbish. To put it another way, the global pollution of the oceans is caused solely by humans. The pristine seas and beaches of the world were unsullied until, say, the last 200 years. In 4 or 5 generations, all that has changed irreversibly.

Leave only Footprints - Delphi Beach, Abaco

My rather (= very) negative intro is counterbalanced by some more positive news: there are plenty of good guys out there working hard to make a difference to the rising tide of filth polluting the oceans. Clearing seas and beaches of plastic and other debris. Collecting tons and tons of abandoned fishing gear. Rescuing creatures trapped, entangled, injured and engulfed by marine debris and pollutants. Educating adults and – far more importantly – children and young people by actively involving them in their campaigns. Conducting research programmes. Lobbying and protesting. And a lot more besides.

The NOAA and sister organisations carry out massive programmes of clearance of marine debris, with working parties of volunteers who do what they can to deal with an intractable problem.Clearing Beach Debris (NOAA) Clearing Beach Debris (NOAA)

But you don’t need to be on an official working party for a large organisation. In the Bahamas and on Abaco, the BAHAMAS PLASTIC MOVEMENT, FRIENDS OF THE ENVIRONMENT  and BAHAMAS NATIONAL TRUST among others, do wonderful work on a more local level.

Elsewhere, some tackle the problems caused by particular types of trash, balloons being an excellent example. I have posted before about BALLOONS BLOW, the brainchild of two sisters who learnt of the serious consequences to wildlife caused by mass balloon releases. Their work has been so effective that increasing numbers of mass releases are being cancelled in favour of other forms of celebration. A minus for balloon-makers of course, but a big plus for wildlife. The BB sisters also keep their own beach clear of the junk brought in on every tide.

And on an individual basis, any old fool can make a tiny difference to a local beach. Here is one such doing just that…

MARINE DEBRIS: BALLOONS – WHAT GOES UP MUST COME DOWN…


Marine Debris - Balloons & Plastic (Balloons Blow)

MARINE DEBRIS: BALLOONS – WHAT GOES UP MUST COME DOWN…

Two sisters, Chelsea and Danielle, grew up by a Florida beach. With their parents,they learned from an early age to collect rubbish from the beach and to keep it clean. When they were little, the problems weren’t so great. Gradually, the tide changed. Literally. And indeed littorally. As is a common experience with any shoreline these days however remote and unspoilt, all manner of debris washes in on every tide, from plastic straws to SPACE ROCKET FAIRINGS. There has been a massive increase in ‘single-use’ plastic items. Most of it will take years, decades or even centuries to decompose. And there are deflated balloons, with their strings.

As ‘business’ on the Florida beach increased, so it became clear that balloons were becoming a significant problem. The increasing popularity of mass releases of balloons at sports events, civic or institutional occasions, and smaller celebrations means 100s or even 1000s of balloons being released into the sky. In most cases they are filled with helium – a finite resource – which carries them high over the earth. Very festive. Then the problems begin. They get caught in thermals, winds and crosswinds, gales and storms. Whether onto land or water, they all have to come down eventually. The problems caused therefore affect creatures inland, on the shoreline and out to sea.

Marine Debris - Balloons & Plastic (Balloons Blow)

Eventually the sisters decided to take action. They started a website BALLOONSBLOW.ORG, linked to a FB page. They post regularly about their beach clean-ups, now extended to other beaches on the south-west coast of Florida. They also produce balloon-based information sheets and flyers such as these:

Marine Debris - Balloons & Plastic (Balloons Blow)

I have a folder in which I keep some horrific images of incapacitated, dying or dead creatures. I use them sparingly because in the main they are upsetting. Almost every one of them involves entanglement in or ingestion of such materials as plastic, mylar, styrofoam, rubber or latex. Here are just 3 examples involving balloon strings – I’ll spare you others I have collected (e.g. a turtle that died trying to excrete the remains of a balloon).

I don’t have a down on ‘fun’ – and nor do Chelsea and Lucy I’m sure. But, now in their 20s, they have had years of direct hands-on experience clearing their beach and one can see why they decided to take wider action. From one area they have accumulated a vast collection of balloons that will take many decades to break down. Even then, the degraded pieces and micro-pieces will be eaten by fish, turtles and birds.

Here’s an illustration of the problem of creatures nibbling away at latexMarine Debris - Balloons & Plastic (Balloons Blow)

The Delphi beach is very regularly cleaned up, of course, but there’s nothing that can be done to stem the arrival of debris large and small on every tide. Beautiful and remote though the one-mile curved strand may be, one cannot walk far without seeing plastic of some description. As a matter of interest, I tried a test: walking south on the beach in the tide-line, how long would it take to find balloon evidence? The answer was, less than 10 minutes.

The Balloons Blow website is constructive in offering festive alternatives to mass balloon releases, rather than merely chronicling the downsides. The balloons and other plastic junk mostly arrives from the western fringes of the North Atlantic Gyre, in the Sargasso Sea, where the trash gets caught in the sargassum and is eventually forced onto the shoreline by currents, winds and tides.

This post has concentrated on the dangers to wildlife caused by latex and mylar balloons that are sometimes claimed to be biodegradable but are not. There’s more to be said about plastic marine trash, but I’ll keep that for another day.

MAPPING ABACO: READ A NOVEL, TALK RUBBISH OR DISAPPEAR

I am probably the last person to twig the topological significance of Abaco’s location in the world. An email tipping me off about a TV programme led me to investigate further. There turn out to be 3 ways in which Abaco’s position in the Atlantic Ocean is of special interest. Two are geographic fact; and one is located in the grey area between myth and putative evidence-based supposition (if such a nebulous concept exists…). If everyone knew this already, sorry for being so late into the game. But you get some nice maps to look at, gratis, like the wonderful van Keulen map of 1728 above. About the only marked location on Abaco is ‘Hole Rok’ (now ‘GAP ROK’). For a history of Hole-in-the-Wall in historic maps, click HERE

1. THE DISAPPEARING TRICK?

Until the recent email, I hadn’t taken on board that Abaco is within the Bermuda Triangle. The island and its cays are contained snugly into the 60º tip of the western angle of an equilateral triangle based on Bermuda, Miami and Puerto Rico. The NOAA map below could not be clearer: Abaco is squarely within the triangle, if that is geometrically possible.

I wrestled with whether to write an earnest discourse along the lines “Towards a Greater Understanding of Triangle Phenomenology”. Then I thought, Nah! If it’s a myth, what’s the point in examining its credibility. If it’s all true, I would’t want to worry you more than I already have by mentioning it… So you can do the hard graft if you wish by checking out the links below. Or you can just move on to section 2. Or relax in the sun, go fishing, find some nice birds, or have a Kalik or 3. 

THE WIKI ANGLE Excellent potted overview dealing with supposed position, the main ‘unexplained disappearances’, and the possible causes of these – both natural and supernatural. Frankly, this should do it for all but the most persistent, who probably are more widely informed already.

2. WHAT A LOAD OF RUBBISH

Rowing through the Great Atlantic Garbage Patch (sandiego.surfrider)

Abaco also finds itself at the western edge of the Northern Atlantic Gyre. Strictly speaking the Gyre comprises a combination of  four main currents: the Gulf Stream in the west, the North Atlantic Current in the north, the Canary Current in the east, and the Atlantic North Equatorial Current in the south. It is not synonymous with the infamous North Atlantic Garbage Patch, which is contained within the geographical boundaries of the Gyre. The top image gives a broad-brush idea of  the central area of concentration of the Garbage Patch within the Gyre. Abaco looks to be well clear of trouble. But don’t be too optimistic.

North-Atlantic-Garbage-Patch-12Degreesoffreedom-300x204

North Atlantic Garbage Patch (12Degreesoffreedom)

Looking at various sources, there is some variation in the precise boundaries of the Gyre, though Abaco is plainly within it. Q: is it safely beyond the edges of the plastic peril? A: as any resident will know, the naturally pristine beaches tell a tale of constant plastic and other debris brought in on the high tide almost daily. The incidence depends to an extent on weather and wind direction, but the overall picture is of a relentless intrusion of rubbish on golden and white sand expanses. There is an extent to which what the tide giveth, the tide taketh away; and of course many beaches are scrupulously kept clean. NB I’m not trying to propagate anti-visitor publicity – many people will have experienced the same situation elsewhere.

The research map above shows that, although the garbage hotspots and warmspots are well away from Abaco, the ever-widening circulating soup of plastic, rubber and metal has reached the island. Abaco is in the pale blue zone. Yellow is not that far off. Imagine what the orange or red areas must be like. This sort of thing:

In some places the junk stacks up to form islands with hills

Texas has become a standard ‘unit’ for large area comparisons. I notice that several sources describe the main area of the NA Garbage Patch in terms of Texas. But how big is that (BIG!)? To get an idea, I created a map overlaying Texas on an area centred on the Bahamas. So, Texas is this big…

 3. A NOVEL PLACE TO BE?

The Sargasso Sea is named for the SARGASSUM seaweed found in large concentrations in the area. Columbus was the first person to sail right across the Sea, in 1492 (well, he and the crews of his 3 ships Niña, Pinta, and Santa Maria). He noted the large areas of seaweed that his expedition’s ships had to plough through. Eventually he made landfall on San Salvador, Bahamas.

This fine Krümmel map from 1891 shows the extent of the sea, and you’ll see that its western fringes reach the ocean side of Abaco. Have you seen the seaweed pictured below the map? That’s Sargassum.

EIGHT FACTS ABOUT THE SARGASSO SEA TO IMPRESS YOUR FRIENDS
  • Jean Rhys’s famous 1966 novel ‘The Wide Sargasso Sea’ is actually set in Jamaica (nb the Sea is mentioned!)
  • The Sargasso is the only ‘Sea’ to have no land boundary, being entirely in the Atlantic Ocean
  • It is vital to mass migrations of eels, where they lay their eggs
  • Young loggerhead turtles are believed to head for the Sea for seaweed protection while they grow
  • Much of the debris trapped in the NA Garbage Patch is in the Sargasso, and is non-biodegradable plastic
  • The Sea is protected by Commission established in 2014 involving at present 5 countries, including (unbelievably) Monaco, the second smallest country in the world at 0.75 sq miles. Green Turtle Cay is about twice the area!
  • Cultural references include the track “Wide Sargasso Sea” on Stevie Nick’s “In Your Dreams” (2011)
  • There are loads of other literary & musical references but I lost the will to pursue them when I saw the inclusion of ‘Dungeons & Dragons’

 MUSICAL DIGRESSION

While writing this post I have had a song thrumming annoyingly inside my head. It’s ‘Bermuda Triangle’, with its coyly rhyming ‘look at it from my angle’. Now it’ll be inside your head too! I couldn’t remember who it sang it. Rupert Holmes? No, that was the egregious “Escape (The Piña Colada Song)” (1979). Ah yes. Barry Manilow. Bazza Mazza. The Bazzman. As you’ve finished with the maps etc, here’s a musical memory with a counterbalance of the Stevie Nicks song mentioned earlier…

Those cover the Triangle and the Sargasso; what of the Garbage? Try some Fresh Garbage from Spirit…

OPTIONAL MUSICAL NOTES Randy California’s fingerpicked intro to ‘TAURUS‘ is remarkably similar to the later, far more famous guitar work of Jimmy Page’s intro to ‘STAIRWAY TO HEAVEN‘. And Spirit happened to tour with the early Led Zep. Legal action was commenced last year for copyright infringement, as yet unresolved… You be the Judge!
