Beautiful 3D map of the Great Barrier Reef

Led by geologist Robin Beaman, some of the clever folks at James Cook University in Townsville, in the northeastern Australian state of Queensland, have mapped in three dimensions and with unprecedented precision the seafloor off the Queensland coast.  In the process produced they’ve produced some spectacular imagery.

 Gorgeous isn’t it?  The map was made by melding together single beam and multi-beam sonar observations from ship-mounted equipment, with light detection and ranging (LIDAR) data, which are laser measurements taken from satellites.

Multi-beam sonar used to map the ocean floorBut it’s the scale thats really amazing here.  The path of the fly-through in that video is over 1,350 miles, or the distance from Miami to Provincetown (Cape Cod) or from the Straits of Gibraltar to the coast of Greece.  And they covered all the way from the Queensland coast to New Caledonia, encompassing an area of 6 million square kilometers, or about 2.3 million square miles.  Thats about the same area as the lower 48 states, except Texas, mapped - underwater mind you - to 100m resolution!  It was a mammoth job.  In the process they discovered some previously unknown features and, importantly, mapped the entire Great Barrier Reef, the worlds largest coral reef ecosystem.  These sorts of things will make the map an invaluable tool for folks at the Great Barrier Reef Marine Park Authority, who are charged with the management of this vast area.

You can read more about how they made their map here and a good story about the work in Australian Geographic here.

Me and Terry Hughes, we got Kwan

This is a little spooky. Terry Hughes of the Center for Excellence in Coral Reef Studies in Australia, whom I know only vaguely, has been quoted on the topic of the Shen Neng 1, that Chinese coal ship that ran aground on the Great Barrier Reef. His somewhat dismissive tone sounds creepily like my recent rant on the subject.

He said:
"The [Shen Neng 1] ship grounding, in the scheme of things, is not a major incident. It's bad if you happen to be one of the corals the ship parked itself on, but it's tiny in the face of the real problem: global warming."

I said:
"I am not worried in the slightest about this incident.  Not that its a good thing - far from it - but this accident is nothing more than a tree, obscuring us from seeing one big and scary forest [burning fossil fuels]."

Terry, you're my Ambassador of Kwan.

Q: When is a ship like a tree?

A: When you can't see the forest for it.

You may have followed some press in the last week or so about a Chinese coal ship, Shen Neng 1, that ran aground on the Great Barrier Reef and spilled some of its fuel oil.  This has caused a regular frenzy in the Aussie media and the global conservation and environmental news-o-sphere.  There have been all sorts of calls for prosecution of the shipping company and new stringent regulations for the transport industry and so on, along with dramatic accounts of the damage the ship did and the risky salvage operation that came next.  But you know what?  I am not worried in the slightest about this incident.  Not that its a good thing - far from it - but this accident is nothing more than a tree, obscuring us from seeing one big and scary forest.

The main reasons I am not especially bothered by the Shen Neng accident are that (1) it affected a very limited area - the G.B.R. is really B.I.G. and one ship can only damage so much of it; and (2) it was a single event in time - this was not a process or an ongoing problem, but a singular disturbance.  Science shows us that the GBR, and reefs in general, are amazingly resilient to violent disturbances like this; a decent cyclone can literally turn a reef upside down, and a couple of years later you'd never know the difference.  Indeed, periodic disturbances may  be really important for maintaining a healthy reef ecosystem.

No, the Shen Neng is just a tree, obscuring us from seeing the forest that really threatens the future of the GBR and all reefs.  Its not the 2km gash that the hull cut in the reef, nor is it the tons of fuel oil leaked into the water; it's the very concept of burning that fuel oil, and burning the thousands of tons of coal that the Shen Neng 1 was carrying.  When you consider all the other ships and all the coal and fuel they were carrying that day and every day, and all the cars in the world, the power plants and so on ... ach, you get my point.  THAT'S what we ought to be worried about, because both of the main effects of increased atmospheric CO2 - warming and ocean acidification - will likely result in unrecoverable damage to All reefs. Everywhere. In our lifetime.  Warming is directly linked to lethal bleaching events, while acidification disrupts the ability of reefs to lay down their skeleton and grow.   Oh yeah, and lets not forget the drowning effects of sea level rise, too.  The more I think about it, the more it seems that jumping up and down about the Shen Neng is hypocritical (coal is one of Australia's biggest exports, after all) and akin to complaining about the deck chair arrangements of another, even bigger, ill-fated ship.  (Ironically, if Titanic sailed today, she probably wouldn't have to worry about icebergs...)

Of course, its a false dichotomy, we should be worried about BOTH the Shen Nengs of the world AND the global climate change/ocean acidification.  But I only have so much energy/capacity for worrying about these things, so with a limited anxiety budget, I feel compelled to focus on the bigger issue and what (if anything) we can do about it - to try to reduce consumption and to try to make sensible decisions that are mindful of how much energy is involved and what the broader impacts might be.

In other words, to worry about the forests - and let the trees take care of themselves.

Field locations you have loved

In this thread I want to hear about field locations YOU have loved, and WHY.  Here's a couple of mine to get the ball rolling:

Kedron Brook, Brisbane, Australia.  A choked little stretch of suburban creek on the north east side of Brisbane Australia was a key field location for my PhD research, which was all about introduced (exotic) species and their parasites in rivers and streams in Australia.  At one point just above the tidal influence - stylishly named KB216 for its map reference - this creek is basically completely exotic: plants, invertebrates, fish, the whole shebang.  There aren't many parasites there, but those that were present were introduced hitchhikers.  Not sexy, but a veritable Shangri-La for a student on the hunt for ferals...
Heron Island, Queensland, Australia.  Where I met and fell in love with marine biology.  A patch of sand and guano-reeking Pisonia forest 800m long, on a reef 10 times that size, crawling with noddies, shearwaters, turtles, grad students and squinting daytrippers or more wealthy sunburned resort guests.  Too many firsts for me there to even list (but no, not that one - get your mind out of the gutter!).  Absolute heaven, hands-down.  How do I get back?

Throgs Neck, NY, USA.  You generally wouldn't think of the junction of Queens and the Bronx as a biologically interesting in any way (except maybe on the subway), but actually the western part of Long Island Sound was the epicenter of a lobster holocaust that started in (well, before, if you ask me) 1999.  When we were out on the RV Seawolf, the Throgs Neck bridge marked your entry into the East River and the start of one of the most unique and strangely beautiful urban research cruises around, right down the East side of Manhattan, past the Statue of Liberty and out into the Lower NY bays.  We would pass through on our way to do winter flounder spawning surveys off the beach at Coney Island (its that or go around Montauk).  Proof that not all interesting biology takes place in Peruvian rainforests...

In the comments, tell us about a field location YOU have loved and why.  Post links if you can find them.
