Philippines

Bangka
Eeeek, I have a lot of blog catching up to do! Where to start? OK, so for those that don’t know, a big part of my PhD work is going to be done in the Philippines - yes, I know, it’s a tough life. I spent a couple of weeks out there at the end of August to learn some fish, meet some people, and generally get a feel for where I’m going to be working.

I’m going to be based in Dumaguete, Negros Oriental (Google Earth is your friend). It’s a lovely laid-back studenty town, I can see myself living here for a while. Most of this trip was spent island hopping around the region, looking at lots of different dive sites and becoming a fish geek again. The diving out here is amazing, the weather was uncharacteristically calm for the time of year so the vis was great, and there’s tons of life. Definitely looking forward to going back!

Diving Kangaroo Island

Crikey, it seems like a long time ago now, but here’s the rest of my holiday reports!After being blown out on the first couple of days, we finally managed to get underwater. Everyone else had their drysuits, and I was super-shivery in my 5mm wetsuit in the 17C water, but it was totally worth it!

Jim (Thistleton, of KI Diving Safaris) explained that the North coast of Kangaroo Island is the confluence of two major current systems, which leads to a bizarre combination of tropical and temperate species. The diversity of seagrass is just amazing, and everywhere is teeming with fish life. Jim guarentees that he’ll find you a leafy seadragon within two days, or he’ll give you another two days diving for free. That sounds pretty cocky, until you meet the guy, and you realise that he just knows the underwater environment here so well. True to his word, we found our leafy on the second dive.

By the end of the first day we were all experts at spotting the weedy seadragons, which stand out as being much bluer than the surrounding seagrass, but we had no chance at all with the leafys! Jim had to practically pick the thing up before I realised what he was trying to point out to me, and if you blinked for just a second they would disappear before your eyes! They really are masters of camouflage. But the undewater attractions don’t end with the seadragons. We had huge groupers and wrasse (bigger than me!) which followed us around, and pufferfish, and lobsters, and best of all - seals! It’s amazing how just looking at a seal can make you feel warmer! Just as we were ending our first dive we caught a glimpse of two playing below us… a teaser for what was to come.

On our final dive, we went for a ’seal dive’ - over to the rocky gullies where Jim knows they like to hang out. We quickly found three seals, who were happy to play with us and hung around for the whole dive! Before we went in, Jim taught us how to speak basic seal - we had to look fun to play with, or they would get bored quickly and move on. So there we were, akwardly somersaulting and spinning around desperately tring to entertain some very bemused looking seals! I’ve never felt so clumsy underwtaer before, they just move so quickly and elegantly through the water, it’s breathtaking. With all that underwtaer excersise I wasn’t cold for a second, and I had to keep checking my air, which was disappearing quick! It’s difficult to imagine how you could have more fun than that on a dive!

Diving on Maggie

Well I finally made it over to Magnetic Island yesterday, to do some shore diving with a few guys from the dive club. We got up super early, took the ferry over and had breakfast at one of the (many) backpacker places before driving over to ‘Pleasure Divers’ to hire some tanks.We did a shore dive in Geoffrey Bay, right by the dive centre on a little wreck called the Moltke. You can read the story about it here. I had been warned that the vis probably wouldn’t be great, but I was amazed at how much we saw! The wreck is just 100m or so off the beach and is really shallow, between 4m and 8m - almost a snorkelling wreck! Our navigation was pretty rubbish though, we’d be swimming fine on our bearing then would get distracted by a fish or something, and then we’d get lost, poke our heads up to check the bearing and be amost 90 degrees out! There was lots to see in the seagrass and coral bommies on the way, brightly coloured nudibranchs, little gobies, a lobster and a lionfish.The wreck itself is beatutiful. It looks as though it’s completely made out of coral now, and theres still enough structure left standing for there to be little swim throughs and stuff. Someone who knew more about boats than me could probably tell what bits were, but I would guess at a bow and a mast or two. There were schools of yellow and silver snappers everywhere, big batfish hanging around the edges of the wreck, a couple of boisterous unicorn fishes zipping around the top, and some HUGE angelfish at a cleaning station - where they get cleaned by little cleaner wrasse. I’ll have to find pictures of all these for the non marine biologists, so you know what I’m talking about! The fish didn’t seem to mind divers being there at all, usually they scatter when you get close, but swimming through a bit of the wreck I was practically brushing them out of the way. Then just as we were about to leave the wreck a big green turtle came past too, which was fantastic. All of this just off the shore and a half hour ferry ride from home!Magnetic mini mokesBecause it’s so shallow we were underwater for over an hour, even on little tanks, and the water was a toasty 28C - I was hot in my 5mm wetsuit. By the time we all got back on the beach we decided there wasn’t enough time for anpther dive AND food before places started to close, so we had a vote and decided to head to the pub. We didn’t think anything could top the first dive. So we had a nice afternoon with a few jugs of cold beer and some pub grub before catching the ferry home. Really great day - Maggie is beautiful and I’ll have to go back soon to explore more. A few more photos on flickr.

Riding the E.A.C!

Yongala turtleI had an AMAZING time last week - diving the outer reef with the JCU dive club on a boat called Kalinda.The weather was perfect at the start of the week, so the first stop on monday was the Yongala wreck, which totally deserves its reputation as one of the world’s best dive sites… it was absolutely fantastic! There’s usually quite a strong current over the wreck, but on our afternoon dive it was perfectly still, not a breath of current. You can barely see the wreck itself, because it’s completely covered in colourful soft corals, anemones and sponges, and huge shoals of silvery fusiliers and snappers mmake walls of fish which move and scatter as you swim through. And then there’s the big stuff. Groupers that are easliy bigger than me hiding in holes in the wreck glaring at you with their ugly faces, reef sharks and huge trevallys dart in from the blue water around to snatch little fish, and a couple of big green turtles swimming leisurely through everything. There was just so much to see it was impossible to take it all in on one dive, I could spend weeks on this site! Unfortunately you’re not allowed to go anywhere where your bubbles might touch the wreck (because it’s a grave, and they’re worried about it deteriorating), so I had to just peer into the holes in the wreckage.We then got another chance to dive the Yongala… at night. The current had picked up a bit, so we had to move carefully around staying close to the wreck to avoid getting ‘blown away’. The huge trevallys were in full hunting mode, and were using our lights to pick off little fish, so lots of them would come racing at you out of the darkness and turn right at the last minute - pretty scary! After a while we learnt to have fun by lighting up a little fish and watching as everything scrambled to eat it! There were about 10 of us in the water at once, so the wreck was lit up with a multi coloured lightshow of cyalume sticks and torch beams, which would flash like crazy when someone found something good. As we were returning back along the top edge of the deck to the shot line we found three or four huge bull rays hovering over the to pof the wreck feeding in the current, all stacked up like pancakes. It was just breathtaking to watch. They didn’t seem at all put off by us, and one brushed right past me.ClownfishAfter a bumpy interrupted nights sleep, we woke up on the outer reef, where the water is clearest and there’s most to see. Typically we would do a couple of dives in the morning, move a bit, do an afternoon and night dive and then move further up the reef overnight. Some of the dive sites were just breathtaking, straight out of finding nemo! I can’t describve them all here or I’d go on forever! Beautiful reef drop-offs, enquisitive little reef sharks, clouds of bright blue damselfish hovering over coral bommies, quite a few turtles and rays, big pufferfish, enormous groupers and plenty of anemonefishes. Several sites had amazing caves and tunnels in the reef that you could swim through and find lots of little fishes hiding in the darkness. Unfortunately I don’t have many photos, cos my camera housing flooded :( Hopefully I’ll get some from the others on the trip.All in all it was an exhausting, but very fun week. Met lots of fun people too. Unfortunately it’s taken me nearly a week to get over my landsickness!

Great Keppel Island trip

According to Carl Svendsen’s Souvenir Chart of Great Keppel Island, ‘Great Keppel is a big, dry, rugged and mostly uninhabited island with dangerous cliffs and foreshores’.The whole island is rather run down and scruffy, as though nothing has been done to it in years. Paint is flaking, signs fading in the sun and the jukebox has hits from the mid-nineties. In it’s most recent incarnation the resort attempts to attract families, but signs of its ‘party island’ past remain in the Wreck Bar on a Saturday night. From Friday to Sunday the island is busy with day trippers and weekenders, but for the rest of the week the place is empty, almost as though abandoned, and it feels quite odd. The exception is Island Pizza (a slice of paradise), which serves surprisingly good pizzas on a tastefully decorated deck populated by palm trees. This makes a welcome break from the mediocre staff meals at Keppel Haven, with classic rock DVDs (Bon Jovi appear to be a particular favourite) projected, slightly out-of-focus, onto a big screen.It’s odd that the resort is so neglected, given that the island is stunning. The beaches have fine white sand, which your feet sink right into, and all around there are amazing views out to other rugged, uninhabited islands. Hiking tracks (which sadly I didn’t have time to follow) lead up to a peak in the centre of the island and to remote beaches around its shores.Lutjjanus carponotatus - stripey fishThe purpose of the trip (at least the bit I was there for) was to try and locate spawning aggregations of coral trout and stripey sea perch, and to collect DNA and otolith samples from these species to determine when they spawn, and how populations in the island group are connected. We didn’t have much luck finding any spawning aggregations; they’re going to try again next month. To get the DNA and otoliths (which are essentially fish ears, inside their heads), we had a permit to spearfish on scuba. This is usually illegal, apparently because it would make it too easy to catch them…. Yeah right! I failed to spear a single fish the whole time! Which I think makes me the worst spearfisher ever. But at least my karma is intact I suppose. Once we’d (ok, the others) had caught them, we had to take fin clippings, remove their otoliths (gruesome photo warning)… fillet and barbeque them! It would be a shame to waste anything! We also did an ‘underwater fishing’ trial, which was basically fishing with a baited line like normal, but underwater. It was hilariously unsuccessful, all the fish we wanted to catch simply nibbled the bait off and left the hook behind, and one dumb other fish got itself hooked (and released) three times! All the bait in the water attracted a rather pesky remora and a tawny nurse shark, which just complicated matters further! I laughed lots.The days were pretty long, and it was super hot being out on the boat all day, but it was good fun and I learnt quite a bit from chatting to the guys. I flew back up to Townsville this morning, and am knackered. Back to the office tomorrow!

Orpheus Island

Orpheus Island Reserach Station, originally uploaded by marinegirl.I’m currently on Orpheus Island doing my scientific diver course… an island with wireless internet!We’re staying at the JCU research station, which I think can sleep about 30 in total, but theres only 10 of us here at the moment, so it’s nice and quiet. Theres four of us on my course, plus instructor, and a few other guys trying to catch damselfish for an experiment - but they’re not having much luck! Its a really good set up, lots of dive boats and equipment, aquaria, labs and a lecture theatre. We’re staying in the student digs, which are bunkbed rooms with a big communal cooking/eating/tv area. Very comfy!The island is lovely, a pretty sandy beach and some mangrovey bits in our bay, and dense vegetation behind us. I’ve put a few piccys up here. Theres no vehicles on the island (apart from a tractor to pull boats around) so I haven’t really seen much further than that. Theres a posh resort in the next bay along I think, but thats it for the whole island.We’ve been doing all sorts of rediculous diving things… using full face masks so we could talk to each other underwater today, which was a lot of fun. Underwater drilling tomorrow! All this fresh air and diving is really tiring, so I’m off to bed now, I’ll let you know how the rest of the course goes when I’m, back home!Becks
