Marine Explorer

Bleached anemone with Amphiprion perideraion, pink anemonefish #marineexplorer by John Turnbull Via Flickr: There is a small section of unbleached tentacles down the bottom of the pic. One Tree Island, Steve's Bommie

Happy to see a big healthy Porites bommie #marineexplorer by John Turnbull Via Flickr: Our surveys and photogrammetry have to cover sites without fear nor favour, so it's nice to find a big healthy colony on one. I wonder how old this one is? One Tree Island

Coral survivors (just) #marineexplorer by John Turnbull Via Flickr: At this lagoon 2 site on One Tree Island, the majority of corals have died previously. Among the few survivors, many are now bleached. There are two small bleached Galaxea colonies in the foreground, and an unbleached Montipora.

3D mapping of the reef #marineexplorer by John Turnbull Via Flickr: This is our detail mapping rig, with 2 x Sony A7 IV cameras set to take a photo every second. A 10 m plot of reef requires over 1000 photos. One Tree Island, southern GBR

Bleached corals at 18 m by John Turnbull Via Flickr: One Tree Island

Echinopora coral #marineexplorer by John Turnbull Via Flickr: Nice to see this large colony of unbleached Echinopora at One Tree Island. This pic is a fraction of the overall stand, and it was full of diverse fish life.

Mantis shrimp playing peek-a-boo #marineexplorer by John Turnbull Via Flickr: We spotted this large Stomatopod after our surveys yesterday. It came out and watched us, we watched it, it ducked back into the coral patch and came out another hole, we watched each other again, and on it went for several minutes. Who was playing with whom?

White's seahorse in the Carijoa - can you see it? #marineexplorer by John Turnbull Via Flickr: It's a bit easier with the lights on too :) Clifton Gardens.

Brown sabre-tooth blenny #marineexplorer by John Turnbull Via Flickr: One's home is one's castle. Clifton Gardens

Red rock crab under the jetty #marineexplorer by John Turnbull Via Flickr: Clifton Gardens, Sydney Harbour. Exploring the capabilities of my new Samyang 12 mm behind dome port.

Always a fan of fans :) #marineexplorer by John Turnbull Via Flickr: Jervis Bay

Bryozoan anemones - natural starbursts #marineexplorer by John Turnbull Via Flickr: Jervis Bay

Curious wrasse drawn to bubble pocket #marineexplorer by John Turnbull Via Flickr: When we survey in overhangs our bubbles can form pockets of air on the underside of the rock. This crimson banded wrasse was most interested in the bubble formation. Jervis Bay RLS.

Big and small; one banded wobby, but hundreds of tiny shrimp #marineexplorer by John Turnbull Via Flickr: Jervis Bay

G. prasinus moray - all the better to smell you with #marineexplorer by John Turnbull Via Flickr: Moray eels are generally night hunters. Their eyesight is poor as it has given way to a keen sense of smell as their primary means for finding prey in the dark. Check out those nostrils!. Jervis Bay

Blue devil fish P. bleekeri #marineexplorer by John Turnbull Via Flickr: One of my favourite fishes, especially when it comes out of its cave on transect. Jervis Bay RLS
