Raven Channel, Julian Reefs and Dobu
Milne Bay, Papua New Guinea
23rd
March 2006
We departed Alotau, anchoring for the night at Killerton Islands,
close to the mouth of Milne Bay. Thursday morning, a pod of bottlenose
dolphins swam beneath a rainbow towards the mangroves. We moved
on towards Raven Channel, a site we know well from our previous
times here. A large pod of spinner dolphins clustered around the
bow as we moved towards our anchorage.

By afternoon, we were immersed on the reef we had previously
named ‘Magic Spot’. Indeed, it still is magical! We
conducted a Vitareef study here while also making observation
dives at several nearby sites including one called ‘the
Lighthouse’. Strong currents raged over these reeftops at
times, turtles floated through, small anthias danced in the water’s
movements, napoleon wrasse drifted by, and a pufferfish permitted
close scrutiny.
We spent four days at this anchorage, moving on Monday to the
Julian Reefs, off the west coast of the mountainous Normanby Island.
These reefs are a series of underwater ridges forming a broken
barrier reef system. There was hardly any current here and without
the cooling effects of constantly moving bodies of water, there
was a significant amount of bleaching. We conducted a bleaching
transect and counted 55% of colonies bleached within the 80 square
metre zone. However, the reef is still breathtaking. The wall
is fairly steep, almost vertical in places, and the reef top is
a picture postcard of table Acroporas interspersed with a dazzling
array of other genera.

As we brought the ship through the channel between Normanby and
Goodenough Island, clouds rolled down the steep volcanic masses,
enshrouding areas of pristine forest. Sailing canoes passed us
by. We moved through the channel with Dobu in sight at the end
of it. This is an extraordinary looking island – steep green
ridges rising from cliffs above sea level to a plateau. A strong
current rushed past Heraclitus and we watched as canoes
paddled steadily against it to return home.

The underwater excitement here is at a dive site called ‘the
bubble bath’ – volcanic vents steam off in the shallows
beneath Dobu beside coral bommies and a seagrass bed. Above water,
friends were made in these new waters for us, including Jericho
who will be part of the team leading a party of sailing canoes
in the festival at the end of the year. Kula and sailing cultures
are strong here - one going in hand with the other.
