Lizard Log 26/8/14 – 30/8/14

Day 25 26/8/2014

The wind had dropped slightly this morning so we braved the lagoon again. We went to a site on the edge of the Palfrey reef system which I hadn’t been to before. The coral there looked to be in quite good condition. It would be worth doing some more transects along there. It was a bit surgy underwater, but the reef gets a bit of protection from the Bird Island reef. As we were swimming back to the boat, after completing our transects, we found a huge plate coral with a big school of sweet lip under it. They were pretty curious and came right up to Kylie for a photo.

We did our second dive on another section of the same reef. We decided to try this section because we were on a falling tide and the reef edge was deeper than the first site. Unfortunately the reef edge had none of the corals we needed, so we went up onto the reef flat. It was nice and protected in behind the big Porites bommies which made up the reef edge. We found a few G. brochus colonies up there which was good as I haven’t been able to do too many transects on them yet. It just takes me forever to find the little buggers as they bury themselves deep in A. loripes heads, which are really dense.

As we were heading back to the boat, we found several artificial reefs out on the sand. One of them had a plastic cage over it. It looked like an abandoned caging experiment. We took a couple of photos and then headed to the boat. We told the director about them and found out that it was a really old experiment, long since finished. They will be removed soon. It’s a bit of a shame as they now have quite a bit of growth on them. But it is a good reminder that we need to remove all of our equipment from the field when we’ve finished. Especially when working in a World Heritage area.

This afternoon we said farewell to the two Australian Museum researchers who had been our lab buddies for the last five days. They were good fun to share a lab with.

Day 26 27/8/14

Today we went back to the same reef system we’d visited yesterday. The wind had picked up again, but it was still quite manageable underwater. We got some great data over our two dives. The only downside was that the battery on the GoPro ran out so we couldn’t take photos of the corals on our second dive. It’s not essential, but it helps with coral identification and I’m planning on revisiting all the photos to make a visual complexity estimate of the corals.

We found a couple of beautiful big Nembrotha nudibranchs (I think) on our first dive.

Day 27 28/8/14

Kylie and I headed out to Palfrey again today. One of the Bshari lab group students came out with us today. She was documenting wrasse interactions with cleaners. She snorkelled around the boat, following fish, while Kylie and I went about our business. Luckily, she is Swiss, so she didn’t get cold on the surface while Kylie and I froze on our two 90 minute dives. Acclimatisation is a …. not very nice thing….

Kylie spotted an octopus watching us from a hole in a coral head on our second dive. After we’d completed the transect near our friendly cephalopod, we swam off to find a new transect site. When we found a good spot, Kylie swam back to collect the transect and bring it to our new site. She swam past the octopus’ hidey hole, but it wasn’t there anymore. When she got to the transect, the octopus was there checking it all out, running its tentacles over the PVC tubing and tape measures. When it saw Kylie it ducked into a hole, but kept one tentacle on the transect. They’re such inquisitive animals!

Kylie and I were both feeling quite tired in the evening so we decided to have an early dinner and get an early night. I love socialising here with the housemates, but it was so nice to lay down and turn my brain off early.

Day 28 29/8/14

Kylie and I had a bit of a later start today because our resident baker, had made bacon and cheese rolls for breakfast. Delicious! I’ve said it before and I’ll say it again; Awesome housemate!

The wind was blowing hard today. We had a pretty rough boat ride out to our site today. Kylie and I were both feeling pretty knackered today so we decided to just do a single dive at Trawler Beach. Under the water, the conditions were quite manageable and we got four transects completed.

This afternoon I got stuck into organising my data. It’s a big job so it’s good to get a head start on it before I get back from the field. I also took the opportunity to catch up on the emails that have been building up and filling in some of the collection forms for the various permits and databases I’m a party to.

Day 29 30/8/14

Kylie and I got back out to Trawler today for our dives. The wind was still blowing hard on the surface, but underwater was fine. It felt cold though! I’m going to have to resort to zipping up my wetsuit I think.

We decided to pick our way through the patch reefs and head to Trawler Beach for our surface interval. We took shelter at the eastern end of the beach, near the mangroves. The water was beautiful and still there and it was reasonably out of the wind. It was still a bit cold though as it was a pretty overcast day. I know we’re supposedly in the tropics, but it is cold in a wet wetsuit with a 30 kt wind.

As I was donning my dive gear in the water for the second dive, a big green turtle came up from the reef to see what was happening. It circled me and then casually swam off when Kylie turned up with a camera. It had two great big remoras accompanying it. One of the remoras was bigger than the poor turtle’s shell!

It was BBQ night again tonight. The decision was made to hold the BBQ in the beach house because of the wind. Although the wind had dropped by the time we went down to the beach for sunset drinks and it was actually quite pleasant. It’s more intimate in the beach house though and you can talk to more people so it was fine.
