23rd August 2009, SOSSA PELAGIC TRIP, WOLLONGONG, NSW, AUSTRALIA.

Report prepared by: P.J. Milburn.

Swell: SE to 1.0 to 1.5m.
Weather: Warm and sunny with clear skies all day.

Barometric pressure: 1010 HPa falling.

breezes and NNE 5 to 8 knots in the afternoon.
Sea surface temperature: 17.3 to 19.3°C.
Primary chumming locations: 34° 26'S : 151° 18'E and 34° 24'S : 151° 22'E.

Summary:

A weak high-pressure system in the Tasman Sea
created mild and stable conditions for the
duration of the trip, with a gentle north
northeasterly breeze developing in the afternoon.

Once again, Giant Cuttlefish (Sepia aparma) were
evident on the surface outside the harbour.  The
water was 2.5°C warmer inshore than on the
previous morning but, paradoxically, there were
more albatross and even a NORTHERN GIANT-PETREL
feeding on them.  An Australian Fur-Seal and a
Little Penguin were also recorded close inshore.
While we were enjoying views of rafts of
albatross, including a female WANDERING
ALBATROSS, a lucky glance from the foredeck fell
upon a surfacing KOGIA (PYGMY SPERM WHALE).  It
did not make a ripple on the glassy ocean surface
and despite attracting a small group of Silver
Gulls was not seen by most on board before it
sank gently back out of view without further
observation.

Beyond Wollongong Reef, there were further
sightings of Little Penguin and Australian
Fur-Seals and groups of hundreds of Fluttering
Shearwaters.  Smaller numbers of Hutton's and
Wedge-tailed Shearwaters and Australian Gannets
were also foraging in this area.  In deeper water
we encountered more albatross and we had recorded
Black-browed, WANDERING, Campbell, Indic
Yellow-nosed, Shy and White-capped before we
reached the edge of the continental shelf.
Additionally, we had enjoyed good views of both
NORTHERN and SOUTHERN GIANT-PETREL.  Some amongst
our party, who were visiting from the northern
hemisphere, were already pretty excited by events
thus far.

At the 100-fathom line an adult BULLER'S
ALBATROSS closed in on us and began to feed
eagerly at our stern.  We stopped to set up a
drift-and-berley session in hope of attracting
some storm-petrels as we had done on the previous
day's trip.  We failed in that endeavour but this
was all but forgotten when an ANTARCTIC MINKE
WHALE surfaced virtually alongside.  Happily,
everyone aboard saw this magnificent animal.

We continued eastward and set up a second
drift-and-berley session near a trawler that had
stopped to haul its net.  This also went
perfectly to plan and we attracted a large mixed
flock of seabirds.  Highlights here were NORTHERN
GIANT-PETREL, NEW ZEALAND CAPE and Solander's
Petrels, WANDERING, ANTIPODEAN, Gibson's and Shy
ALBATROSS and a BROWN SKUA.  A large pod of
oceanic Bottle-nosed Dolphins were an impressive
sight as they hurtled past our drifting vessel.

Our cruise back to Wollongong featured sightings
of at least 2 more BULLER'S ALBATROSS and lots
more shearwaters.

Highlights:

A pleasant winter day with bird sightings
dominated by albatross sightings; 9 species in
all that included WANDERING, ANTIPODEAN and
BULLER'S ALBATROSS.
