24th November 2007, SOSSA PELAGIC TRIP, WOLLONGONG, NSW, AUSTRALIA.

Report prepared by: P.J. Milburn.

Swell: NE 2.0 to 3.0m offshore.
Weather: heavy rain squalls early remaining cloudy in the afternoon.
Temperature range: 19.6 to 21.1°C.
Barometric pressure: 1004 HPa rising.
Wind: SSE 10 to 15 knots.
Sea surface temperature: 20.3 to 22.5°C.
Primary chumming locations: 34° 27'S : 151° 16'E  and 34° 26'S : 151° 18'E.

Summary:

A high-pressure system was located over New
Zealand with a trough over the western Tasman
Sea.  A high-pressure system was moving southeast
out of the Great Australian Bight towards
Tasmania.  A cold front moved through our area
just as we were boarding.  This was going to be a
good day to test out our wet weather gear!

Despite the heavy rain there was a good variety
of seabirds offshore and a pair of Sooty
Oystercatchers flew southward continuing their
daily business.  Short-tailed Shearwaters were
the dominant species and a LONG-TAILED JAEGER was
a pleasant surprise close inshore.

We hoped that the rain would soon clear but it
did not.  An adult female WANDERING ALABTROSS
followed us from the 65-fathom line but there was
little else to brighten us up.  Sea conditions
were very uncomfortable in every direction that
we tried and it was a welcome break when we
stopped to drift and berley at the edge of the
continental shelf.  The birds ignored us totally
until the fish oil began to trail out.  Firstly,
Grey-faced Petrels appeared, then a Flesh-footed
Shearwater and right our stern a WESTLAND PETREL.
All aboard were reaching for their cameras when a
cookalaria petrel also came onto the slick.
Luckily it remained close to our vessel for long
enough for excellent images to be obtained,
confirming its identity as a COOK'S PETREL.

After the excitement had abated we continued
eastward to the 200-fathom line and attempted a
repeat performance.  Flocks of Short-tailed
Shearwaters were moving southward but, as often
happens, we could not attract more rarities.
However, the attendant feeding flock included
several Gibson's, at least one ANTIPODEAN and a
WANDERING ALBATROSS.  Immature SHY, White-capped,
Black-browed and Campbell Albatross provided a
great opportunity for close comparison.

Highlights:

After a bird depauperate trip out to the edge of
the continental shelf in miserable weather
conditions we cleared the rain and, almost at
once, the fish oil slick worked its magic by
producing WESTLAND and COOK'S PETREL in short
order.
