Th is was a patch reef with a bottom composition of sand and dead
coral bommies. Marine life included fusiliers, groupers and sweetlips, also
several nudibranchs and several 5cm sea cucumbers. This particular
dive had
no corals to speak of, however, there were several very large
beautiful elephant ear sponges, some large barrel sponges, anemones
and many tunicates. The visibility on this dive was poor,
possibly due to local deforestation.

The bottom composition of this area was mostly dead coral. There
were a few live colonies but a very intense filamentous, coralline and
Halimeda algae overgrowth was present. There
was a very low coral coverage, the only corals present were
Acropora, Porites fingers and fire coral and these corals
were mainly in the shallower zones. There were two beautiful sea
fans at approximately 30m and several bleached sponges at
approximately 7m. Marine life to note included 2 octopi, a turtle, a shark, emperors,
fusiliers and a juvenile harlequin sweetlips. The dives here
had low visibility because the water was very murky. There were a lot of glass bottles on the
bottom.

The dives here were on a gradual sloping wall
to 40m made up of coral rock and a bottom composition of sand.
Marine life on these dives included eagle rays, fusiliers, unicornfish, sweetlips, snappers,
chevron barracuda, jacks and many small reef fish. There were many small coral
colonies with a high diversity of species. There were also some larger
Diploastrea colonies and a high number of sea fans. The
water temperature was 30°C at 30m and visibility was about
15m. There was a strong current out of the
pass running south towards the end of the dive.

The south side of eagle ray pass was a wall with a composition of coral, rock
and dead coral. The bottom
composition at 40m was sand. Over the course of all the dives in this area 4 eagle rays
were seen along with 4 sharks including a white tip, black tip and
grey reef shark. Overall the fish life was very diverse and
included cuttlefish, 7 bumphead parrotfish, a large
school of rainbow runners near the surface, paddletail snappers,
emperors, black and white snappers, fusiliers, angel fish, some
Napoleon wrasse, clown and moustache triggerfish,
schools of barracuda, batfish, lionfish, crocodilefish, anthias
and a large stingray swimming along the wall
which was very unusual to see. Invertebrates included nudibranchs, crown of thorns
and giant
clams. On one dive a sea snake passed very close to the divers.
This area had a diverse algae, sponge and soft coral
coverage. There were large elephant ear sponges and large sea
fans. Coral was diverse
but with a low percentage alive on the wall and the shallow
area was
predominantly coral rock. There was a
large section of Tubastrea. Overall the predominant
corals were Porites and Acropora with several
fire coral colonies. Very
few colonies were 100% healthy and there were a few diseased
colonies. The current tended to run in and out with the tide
and on the majority of dives there was a light current. On a few
occasions there was a strong current running westward along the
wall. The water temperature on average was between 30-31°C.

This site consisted of a sloping reef and bommies with a bottom composition of sand,
rubble and hard substrate. This site was to be our study site in the Solomon Islands, as we had done a study on this same
reef on two previous occasions. It was a chance to have some
comparative data.
During our time here we watched as bleaching events increased.
Many
coral genera were affect ed but most heavily bleached were
Stylophora, Seriatopora, Fungia, Porites, Goniastrea and Acropora. We also witnessed bleaching of
anemones and some soft corals looking paler in colour. Porites dominated the
shallow zones but Acropora, Goniastrea, Montipora, Fungia,
Stylophora, Seriatopora and Pocillopora became abundant
in the deeper zone. The condition of the coral varied around the
study site from healthy coral on the lagoon side to skeletons of
previous Acropora tables on the tip.
There was also a high coverage of
macroalgae, including Caulerpa, and filamentous algae which
did not appear to
affect the live coral.
Fish life on this reef is very
diverse and abundant with a healthy population of commercial fish.
There were many schools of trevallies including bluefin trevallies,
also groupers, snappers, emperors, bumphead
parrotfish, thousands of fusiliers, pufferfish, trumpet fish, damsels
and a school of 10 batfish. Over the course of the study, we we spotted 3 eagle rays, 2 white tip and 1
black tip reef shark.
Invertebrates included several large barrell sponges,
large elephant ear sponges, nudibranchs, a vibrant red anemone,
spaghetti worms, a very small number of sea
cucumbers, brittle stars, hermit crabs in Porites and one
crown of thorns. Also on one occasion
during an observational dive along the study site we
saw one green turtle swimming away in the distance.
Two documentation dives also took place. During the first dive the divers
descended down the wall to the bottom where they saw a grey reef
shark with its mouth wide open at a cleaning station. There was also
a large Napoleon wrasse, a large ray, one lone enormous great barracuda
and a humpback grouper hiding under a sea fan. There was a garden of
Turbinaria and table corals around the marker. On the second dive
there were several highfin groupers, a large bumphead parrotfish
and many Napoleon wrasses at the end of the dive.
The
current varied on all these dives and there seemed to be no pattern
to the times of high and low tides. The water temperature on this site varied from 30-31°C but after a week of bad weather the temperature had dropped
to 29°C.

This
is the island where J. F. Kennedy was famously shipwrecked during
World War II when his boat, the PT109, was hit during a
mission along the Japanese transport route, 'The Tokyo Express'. The
fringing reef around this island had a bottom composition of sand,
rubble and live coral. Porites dominated with some Acropora,
Turbinaria, Galaxea and Pachyseris with approximately 30% live coral
cover and obvious bleaching but also a lot of rubble and a high
cover of macroalgae. There were many small parrotfish, sweetlips and
a black tip reef shark.

This night dive took place at the ship's anchorage near the island of
Mbambanga. The area had a bottom composition of coral rock, rubble,
sand and sea grass. There were many sleeping reef fish, shrimps and crabs. The coral coverage was mostly Porites and there was
one massive Lobophyllia in perfect condition. There was a lot
of sedimentation on the reef and algae overgrowth. No current or swells
were experienced, the water temperature was
30°C and there was a 3/4 moon.

This wreck dive was on a Japanese transport ship from the Tokyo
Express r oute which was hit by a torpedo during World War II and
sank close to shore. This dive was organized with a local dive
company 'Dive Gizo'. We were taken by one of their experienced dive
masters for a tour of the ship. During the dive we saw a torpedo
launcher, machine guns, a lot of ammunition and sake bottles.
We
also saw the place where the ship had been hit. There were many
corals growing on the ship however many of them were bleached
including Pachyseris.
