Great Visibility makes for Rare Fish Sightings
This week has been primo for diving, snorkelling and sun tanning! Visibility has been exceptional on all the northern and southern reefs. Onboard TAKA videographer Eddie discovered a Yellow-Spotted Scorpion Fish at the Temple of Doom mooring site.
A 2-3 meter Tawny Nurse Shark, White Tip Reef Sharks and a Grey Whaler all came to visit at North Horn site, Osprey Reef. A Firetail Dartfish was spotted at “Steve’s Bommie”. Visibility was 30 meters plus.
Onboard Reef Magic this week visibility was also great, averaging at 22 meters. Instructors noted that a lot of the coral was preparing for its annual spawning spectacle, as egg sacks were beginning to form. The triton triggerfish have also been very active, as nesting season for them is also just around the corner.
Tusa has also had an exceptional week. Their boat went out to Cathedral, a rarely visited dive site at the northern tip of Thetford Reef. This dive site boasts a deep drop- off gorge, beautiful stag horn corals and massive gorgonian fans and soft corals a metre in diameter. A head to head fish fight between two wrasse was spotted by certified divers.
These fish are very territorial; it was a fight for the best location on the reef!
The weather folk predict a nice weekend with winds to blow lightly North-to-North Easterly, with maybe a few isolated showers developing on Sunday.
I recently came across and article on flying and diving. Something we often don’t think about as certified divers but know regardless. The article was simple and clear in content that I thought it worthwhile to repeat here.
Flying After Diving (from Diving Vacation Magazine)
A minimum surface interval of 12 hours is required to be reasonably assured you remain symptom free from decompression sickness upon ascent to altitude in a commercial jet airliner. If you have made daily multiple dives for several days or have made a dive requiring decompression, you should extend the surface interval well beyond 12 hours. Most dive operators in Cairns will recommend that you wait 24 hours to fly after diving. The greater the interval before flying the less likely decompression sickness will occur. We recommend that you refrain from alcohol, smoking or drugs before or immediately after diving. You should check with your doctor if unsure about prescription drugs. Being in good health with a reasonably good level of fitness and conditioning sufficient enough to handle moderately strenuous activity will ensure safe participation in diving.
The weekly reef report is written by Sue-Anne Chapman of Pro Dive Cairns, who compiles them from the many conversations she has with divers, dive instructors, captains, and others in the Cairns dive community. The report is published weekly in the Cairn Post, the local daily paper and appears here thanks to the courtesy of Pro Dive Cairns.
