More Freaky Underwater Stuff

I have a few more shots from our recent dive at Magic Passage to show to you this morning. I’m not feeling very chatty today, so you’ll be spared the usual verbal assault that comes along with the pictures. The more images that I process from the Canon G11 the more impressed I am. Now, if I can just find a student, I can get started on something that I’ve wanted to do for years – teaching underwater photography!

This is a cute litte baby Giant Clam (Tridacna maxima) only about as wide as your hand:Awwww, cootchie, cootchie, coo. If you click to enlarge, you will see its “eyes”, which are the turquoise spots around the edges. I had a hard time taking this shot, since I had to get the camera close, but every time I did, the clam would sense the shadow – they can’t really “see”, but simply sense light and dark – and withdraw into its shell.

Here is a nice shot of some Feather Stars (Comantheria briareus):These things are all over the place. There are many different colours. They have little “feet” to hold onto the rocks and they move very slowly about, looking for the best supply of food drifting past. The arms are very sticky and break off easily, so you have to be careful when moving around them not to cause them harm.

This is a beautiful Blue Encrusting Sponge (Haliclona sp):I have noticed that these are spreading like weeds in the area of Magic Passage. I don’t know what that means, but I’m a little worried about it. It is ridiculous that there are no facilities for marine research in Madang, something which I am hoping to do something about soon. More about that later – stay tuned. Anybody out there wanting to do marine research in the area should contact me.

I have a couple of new Sea Squirts for you today. This is a Sea Squirt of the Botryllus genus:The species name was not given in my resource book. It may not even have a name yet. There is so much here that is unidentified. Geeks may notice that the colony is growing on a different kind of Sea Squirt, possibly a species of Polycarpa. You can clearly see the spiracle at the upper left – it’s the big black hole.

This is a Sea Squirt of the Didemnum genus and a real beauty it is:The colour is amazing. You can also see that one Feather Star has chosen this spot to perch for a while. It is interesting that the colours are similar. I can’t imagine that this is anything less than chance, since there are absolutely no brains involved here. It’s blind luck that the hue of the Feather Star and the Sea Squirt colony end up being the same.

Finally, here is another shot of the Papuan Scorpionfish (Scorpaenopsis papuensis) which I showed to you recently. It is a bit easier to see the fish in this shot:Most of the scorpionfish are well camouflaged. The Papuan is a master. I’m the serious photographer in our little mob of divers, but there are several who are better at spotting things. I let them swim around looking for stuff and I wait to hear someone banging on a SCUBA tank. Then I go over an shoot the critter.

It’s good to have friends.

The Papuan Scorpionfish – Junior and Senior

Posted in Under the Sea on January 31st, 2010 by MadDog

Today I have some more shots from my dive at Magic Passage yesterday in a ripping current. That’s exactly what you want at that site, as long as it’s coming in, bringing cold, clear ocean water. It make for great visibility, but it was a little too strong yesterday, making photography difficult. The strong currents there cause a lot of swirling around the features of the passage, so, one second you are being sucked in one direction and the next moment, it’s just the opposite. It can be hard on cameras and heads alike.

But first, here’s this morning’s yummy sunrise, a five exposure panorama:

For the techno-geeks out there, this shot was taken at first ligh, just enough to barely read the knobs on the camera, hand held from the bobbing stern of Faded Glory and shot at ISO 1600. Not bad for a point and shoot camera. Click to enlarge and have a look. There was noise, alright, but I smashed it into submission with the normal settings of Noise Ninja Pro after merging the frames in Photoshop. This is a huge reduction of the original which was about 6000 pixels wide – enough to paper your lounge room wall.

Back into the water, here are some very young Silver Sweetlips (Diagramma pictum)  right at the mouth of Magic Passage. I got this snap shot as I was fighting against the current. The G11 did a fine job:You all know that I like “find the fish” shots. This isn’t the most difficult one that I’ve shown you, but it’s still a good example of a master of camouflage:It’s a rather large specimen of the Papuan Scorpionfish (Scorpaenopsis papuensis),  probably the most common variety of scorpionfish that we see here. Did you find it quickly?

Here is a close up and personal shot of its head:

Pretty, isn’t it? In a functional sort of way.

Thanks to the eagle-eyes of my good dive buddy Rich Jones, I got my first good image of a baby version of the big daddy above. I wouldn’t have spotted this in a million years unless I was stuck on that rock with nothing else to do:It is about 3cm long and fades in perfectly with its surroundings.

I’m very happy with my new G11. The next step is to take both cameras down on the same dive and take identical shots for comparison. Get ready for some techno-babble, but with pretty pictures to soften it.

Then I’m hoping to start conducting on-site UW photography lessons. I”m looking for serious students with at least an Advanced Open Water certificate.

Anybody interested?

As I See the Sea

After yesterday’s marathon post concerning the dumbing-down of science I seem to be at a temporary loss for words. Those who tire of my bombast but enjoy the pretty pictures will sigh in relief. I’m also running three days behind, so I’m using my Time Machine to fake it, as usual. My aparent sloth is not as it seems. I wanted to do a post on Saturday. Unfortunatley, TELIKOM’s so-called “repairs” of my telephone line lasted less than a week, so I never made it online and did not have time to go to the office. Then, on Sunday, my intent was once again to catch up. Unfortunately, our car wouldn’t start . . . yet another headache. Are you tired of my whining. Okay, I don’t blame you. I’ll proceed briefly.

As regular readers will know, I like showing you what I see as nearly as possible the way that I see it. Sometimes “BLUE” is the only way to describe it:The above is a view of the bottom of Magic Passage from about half-way down the slope at about 15 metres on a good visibility day.

Down at the bottom, we were suddenly surrounded by a school of curious Bigeye Trevally (Caranx sexfasciatus):
These characters actually seem to enjoy swimming around divers. I’ve seen it hundreds of times. They commonly swim within a metre of us, their big eyes rolling around like Al Jolson singing Mammy.

These are not particularly good pictures, but that’s okay for today. Not every shot I get swells my head. Some are simply reflections of my experiences that recall moments of pleasure. Here Anita plays with a little mob of Clark’s Anemonefish (Amphiprion clarkii):The cheeky little devils like to nip fingers. I prefer to get my nips bare-handed, but gloves are safer for the diver and for the fish. Who knows what nasty germs lurk on our skin which we may never notice, but would be deadly so some innocent creature just looking for a good time.

You’ve seen many Hawkfish here. However, we don’t always see them in profile, posing as if for a presidential protrait. Here a little Dwarf Hawkfish (Cirrhitchthys falco)  is caught from above:He is not unaware. You can clearly see that he has one eye cranked up to keep me in view.

You’ve also seen the Bluestreak Goby (Valenciennea strigata)  here before.I like this shot because it’s realistic – warts and all. You can see sticks, leaves and other detrius strewn about. Reefs are not neat places, especially close to a river outlet.

This shot also has a nice, natural feel. I assure you , this is exactly what I saw:At The Eel Garden, near Pig Island,  there is a huge anmemone patch full of these Red and Black Anemonefish (Amphiprion malanopus).  The depth is only about four or five metres there, so snorkelers can see this scene with ease.

Back tomorrow with more fish while I catch up with myself. I hope my car is fixed today. Otherwise, I may swim to work tomorrow.

Wrapping Up a Week of Diving

Posted in Under the Sea on January 17th, 2010 by MadDog

We ended up a week of diving, bush trips and industrial-strength socializing with Anita, Wouter and Anita’s father, Jos, today. It’s been a pleasure having them with us. Yesterday I realized that I had no photos of Jos. So, I took this shot of him steering Faded Glory:

Jos turned out to be very handy with a boat. On our last day, he handled the boat while the rest of us did a drift dive at Magic Passage. Communications were a little light, as we do not speak each others’ languages, but he is a very pleasant fellow. I wish that we could have had some heart-to-heart conversations.

Here is a shot of Anita and Swami Monty in the water at Magic Passage with Faded Glory,  Jos at the wheel, coming up in the distance:Anita, Jos and Wouter are leaving tomorrow morning. Wouter is an avid diver and runs with a crowd of dedicated techno-human-dolphins in the North Sea. I wouldn’t be surprised if we begin to get applications for diving here in Madang. It’s an entirely different experience from their normal dives. I think that Wouter found it a pleasant break from the adrenaline-drenched sport as it is enjoyed off the coast of Belgium.

Among the critters that we saw on our last two dives at Magic Passage  and Rasch Passage  was this Starfish (Nardoa rosea)  practicing Extreme Yoga:I am able to contort my body like this, having practiced yoga since I was a pre-teen. Okay, okay, I’m not as nimble and Gumby-like as I once was. However, I’ve not yet reached the point, at sixty-six, at which I need to ask myself, “Can I still do that?” This is a great blessing for me, as the physical activities (yeah, all  of them) are important keys to my well-being. I owe much of this to my Dad, an accomplished athlete, acrobat and dancer who taught me the principles of physical fitness as a life-goal and the concept of the body-aware spirit.

We may as well have a look at another starfish. This one, I think, is a Fromia nodosa  with its little toes curled up very cutely: You can’t swing a dead cat here without smashing a starfish. We have many different species and I have neglected them severely. I’m certain that their tiny little feelings are hurt. I’ll fix that in the future.

I got a bit of a “wow” experience from this huge mob of Reticulated Dascyllus (Dascyllus reticulatus):We would normally see a dozen or two in a plate coral. This was a huge plate and was home to a couple of hundreds of these lovely little purple-lipped fish. I love to play “scare the fish” with the Dascyllus.  If you slowly stretch your arm out over the plate with your hand closed in a fist and then quickly open your hand the entire gaggle will dive simultaneously into the coral and disappear. It’s like magic. Now they’re here – now they’re not. If you look closely, you can see them trembling in their little nooks and crannies where they hide from predators.

Barrel Sponges fascinate me. Some of them are huge. This Xestospongia testudinaria  is about two metres from bottom to top. Some are much larger:

You can see a few Purple Anthea (Psudanthias tuka)  swimming in front of the sponge. The “purple” in the common name is a relative term. As with many fish, the colour that you see underwater is radically dependent on the depth, the colour of the sky and the condition and tint of the water. Sometimes P. tuka  appears purple and sometimes blue. The yellow dorsal fin edging and caudal fin are constant. The fish appear a bit motion blurred, because I was forced to a slow shutter speed by the low light level.

I am exceedingly happy, nay, overjoyed by this image:As you may gather, I’m easily aroused from my usual “so what” attitude. When I saw this fish, I became terribly excited. That will give you an idea of what a fish geek that I am. The reason for my shaking hands and fumbling fingers is that I have never seen this fish before; it was my first sighting. It is a species of Shrimpgoby (Ctenogobiops tangaroi).  There are several fortuitous aspects of this shot, aside from the novelty factor. First, there is the brevity of the sighting. I barely had time to raise my camera, hold my breath for a few seconds and fire off a shot before it disappeared down its hidey-hole.

Another lucky aspect of this image is that I caught the fish’s partner, a commensal shrimp (Alpheus ochrostriatus)  bulldozing a load of sand out of the shared shelter.

I’m not looking a gift fish in the mouth.

Reef Scenes – The Magic Kingdom

Posted in Under the Sea on December 14th, 2009 by MadDog

It has been a joy over the last few years to get truly into the digital age of photography. Having learned the smelly-chemical method before I was twelve years old, I stuck to the film media for several years after the first digital cameras. I had inadvertently joined the massive ranks of ‘serious photographers’ who were shouting down digital cameras of the time as playthings not worthy of the art. They were  pretty miserable at first. My first digital was a 1.3MP model which was okay for snapshots, but inadequate for anything else.

One of the great frustrations (among many) of shooting underwater on film was that I could never, except by dumb luck, get an image to look the way that I saw it with my own eyes  – in other words – natural.  I have discovered, especially in the last year or so, that the secret lies in the techniques used. I’m not going to bore you with all that. If you’re interested, I’ll trade all of my secrets for a case of beer. It’s not a big deal.

However, it does give me severe pleasure to present to you images that look exactly as the diver (me) saw them, or at least as close as I can get. For instance, you often see close-up shots here that are products of careful shooting and laborious processing with Photoshop. The truth is that we seldom actually get that close. Here is a more normal diver’s eye view of a Spot-Tail Butterflyfish (Chaetodon ocellicandus):Spot-Tail Butterflyfish (Chaetodon ocellicandus)It may not be spectacular, but it’s what the diver actually sees. If you are going to get any closer to this little butterflyfish, your name had better be Houdini.

On the other hand, it is sometimes nice to get close. These polyps on a Sea Fan (Acabria sp.)  seem to be a white mass from a metre away. It is only when you get close that you can see their flower-like beauty:Sea Fan (Acabria sp.)It shots such as this, getting the colours right is the most difficult part of the job. When I can sit back and think to myself, “Yep, that’s just as I saw it.” then I know that my work is done.

Here is a group of Purple Anthea females (Psudanthias tuka)  with stalks of Whip Coral (Sea Whip – Junceella sp.)  in the background:Purple Anthea [females] (Psudanthias tuka)The colouration of the Purple Anthea is problematic. In most cases, they do look purple in colour. However when viewed with the light at a different angle, they often appear more blue, as in this image.

Here is a beautiful Divericate Tree Coral (Dendronephthya [Roxasia] sp.)  with more Sea Whips in the background:Divericate Tree Coral (Dendronephthya roxasia)It is such a pleasure to sit back after fifteen or twenty minutes of work and say, “Uh-HUH!  That’s just the way it looked to me.”

Here is another coral species that has been a bother to me for a long time (Tubastraea micrantha).  It is a deep, deep forest green colour and is found only below about twenty metres where the light is beginning to dim to shades of blue:Coral (Tubastraea micrantha)It is devilishly difficult to get the deep green colour without trashing all of the rest, even with Photoshop. This is the best that I have managed so far. It came at the cost of desaturating much of the surrounding area. However, I can attest that the colour that you see on the coral itself is exactly as I saw it. Just ignore the stuff beside it.

Another type of image that I enjoy capturing is the community as a whole. Here is a little anemone garden featuring the Tomato Anemonefish (Amphiprion frenatus).  These are females. The male, in this unusual case, is much less pretty, being more or less solid light orange:

Coral Reef Community with Tomato Anemonefish (Amphiprion frenatus) [female]
It’s such a thing of wonder to glide up over clump of coral and look down on a beautiful scene such as this. I can’t imagine ever tiring of it.

Your mileage may vary.

The Banded Sea Krait – Yikes!

Posted in Under the Sea on December 13th, 2009 by MadDog

Yesterday, for our regular Saturday dive, we had perfect conditions at Magic Passage near Madang. There was a moderate incoming tide and the water coming in through the passage was clear and had very little particulate matter to obscure visibility. The shooting was excellent. I got about thirty usable shots out of 122 exposures. I call that a good day.

The highlight of the dive was an up-close and personal encounter with a Banded Sea Krait (Laticauda colubrina), one of the most poisonous creatures on the planet. Say hello to the yellow-nosed terror:Banded Sea Krait - Laticauda colubrinaI’m sad to lessen my apparent bravery for getting this close by telling you that these snakes offer no danger to a careful diver. Though very poisonous, they are not in any way aggressive, as long as you don’t try to play with them. I have been this close on many occasions. Most of the time, the snake pays no notice at all. If it does seem to notice me, it will invariably simply move farther away from me.

Here is Carol Dover pointing the way to the mouth of the passage.Dive buddies at Magic PassageIt is often said that the mouth of the Banded Sea Krait is too small to bite a human. This is not true. Many fishermen are bitten each year when they try to clear sea snakes from their nets. Here is one swimming through the clear water looking for a hole to investigate for a meal.Banded Sea Krait - Laticauda colubrinaThey feed by moving around through the coral and poking into every crevice. I saw this snake disappear completely twice while I was photographing it. This one was about 1.5 metres long, a fairly large specimen. If you click to enlarge, you will see the flat paddle-shaped tail which helps it to move swiftly through the water.

Hers is why old divers (like me) always tell those not familiar with the Sea Krait to always observe it from the side, never overhead:Banded Sea Krait - Laticauda colubrinaIt is a true snake and therefore must breath air. When it needs to breath, you don’t want to be hovering over the top of it. It might get a little testy if you are cutting it off from its air supply. This one surfaced for about a minute and then came back to exactly the same spot to resume feeding. It did not appear to notice my presence at all.

Aside from air to breathe, the snake also must find fresh water to drink. When the female lays eggs, she must find a safe place on land to do so. I have seen several sea snakes killed by vehicles along Coronation Drive next to the coast of Astrolabe Bay.

Here is another shot of the snake moving through the water. The head is a little motion-blurred in this shot:Banded Sea Krait - Laticauda colubrinaIt’s hard to explain what a kick it is to get so close to exotic creatures such as this and capture their images.

Last week we dived The Henry Leith, The Eel Garden and The Green Dragon B-25 Bomber. You’re going to be served fish for the next few days.

I hope that you’re hungry.

Google Earth Learns About Madang

Posted in Mixed Nuts on March 21st, 2009 by MadDog

I’ve always been disappointed with the satellite images on Google Earth for the area around Madang. Until today. I don’t remember how I drifted to Google Earth again. Something on another web site caught my eye, I suppose. Anyway, I downloaded the latest version and cranked it up to see if Madang looked any better.

WOW! You can see streets and everything. If you try to zoom in to the level of seeing who is parked where, it gets a little fuzzy, but you can see the colours of the cars just fine. No registration reading yet. Can’t see people very well. But Madang is finally coming in crisp and clear:Madang, Papua New Ghinea - most of the town on Google EarthOf course, the first thing anybody does with Google Earth is look for his house. Ours was easy to find. Just south of the end of the airport runway, north of the big pile of wood chips and directly across the harbour from the main wharf:
Our house in Madang is directly across the harbour from the main wharfHere is a shot of Nagada Harbour and the Jais Aben Resort:
Nagada Harbour and Jais Aben ResortThe top island is Leper Island and lower is the north tip of Kranket Island. In between is Magic Passage, one of our favourite diving locations. The reefs are very nicely visible:
Magic Passage - one of our favourite diving locationsThose familiar with Madang will recognise this location immediately. It is the north end of the golf course (at the bottom) and the Coastwatcher Monument at the upper left sticking up like a big white rocket ship. It looks to me as if this shot was taken at about 8:30 or 9:00 in the morning:
The Coastwatcher Monument and the North end of the Golf Course in Madang, Papua New GuineaHere is a nice shot of Kar Kar Island. It’s too bad that the fringing reefs are not visible. Also the cloud cover hides the giant crater where the active volcano sleeps (for the moment):
Kar Kar Island from Google EarthThe shots of Madang were taken before last July. I can tell because the huge mango tree that was behind our office is still visible. We chopped it to make room for an office extension.

It’s cool to join the rest of the world. Now, we too can send someone a link to say, “Here is where I live!”
