From The Scientists 12/03/06 - Percy Islands
We arrived in the Percy Islands early on Sunday morning (4 a.m). We woke up
in a beautiful bay with a white sandy beach and palm trees. We did not do
any dives today, instead we jumped into the zodiac and went to a number of
islands for snorkelling surveys. The Percy Isles are continental (rocky)
islands and so the corals are fringing reefs - not like the swains which are
coral cays and patch reefs. Fringing reefs form along the rocky edges of
islands, and often are characterised by high diversity of corals. There was
not very high coral cover (5-20%) at any of shallow reefs that we
inspected. There were, however, definite signs that this area has been
subject to unusually warm sea temperatures, with approximately 30% of the
corals bleached.
We took the opportunity while we were at anchor to explore the mangrove
lagoon on Middle Percy Island. This lovely little lagoon is a popular
anchorage for passing yachts, and an important habitat for a large variety
of plants and animals, including many species of reef fish.
