22nd March, 2003 SOSSA PELAGIC TRIP, WOLLONGONG, NSW, AUSTRALIA.
Report prepared by: P.J. Milburn.

Swell: southerly to 1.5m.

developing during the day. The rain periods were punctuated with some
sunny periods however.

Barometric pressure: 1017 rising.
Wind: calm at first, SE 10 to 15 kts by mid morning, E 10 to 15 kts in the

Primary chumming location: S 34° 27' - E 151° 26'.
The morning was mild and overcast as we left the harbour. The ocean was
glassy calm but corrugated by a southerly swell. There were no significant
weather systems in our area and the forecast was uncertain but hinted at
light winds from the east. Shortly after leaving the shelter of the coast
a southerly breeze picked up making the going a little uncomfortable.
The Silver Gulls were in the mood to follow us, perhaps a sign of the
changing seasons, which in turn attracted the attention of several Arctic
Jeagers. An assortment of shearwater species was encountered as we cruised
east but their numbers were low. Two intermediate morph LONG-TAILED
JEAGERS joined us at the 75-fathom mark on our way out to the continental
As we cruised over the edge of the continental shelf at the 100-fathom line
seabird numbers began to increase. A SOOTY TERN and 2 LONG-TAILED JEAGERS
were amidst the shearwater flocks but this zone seemed fairly quiet and our
instincts led us further east.
At the 350-fathom line we encountered the first Solander's Petrel of the
season returning to the Tasman Sea for the forthcoming breeding season. As
we reached the 600-fathom line we observed large flocks of shearwaters
feeding on small Arrow Squid (Nototodarus sp.).
We elected to stop here and berley and in doing so we attracted large
numbers of birds, including several Wilson's Storm-Petrels. After some 45
minutes we rewarded by the arrival of a TAHITI PETREL that circled the boat
numerous times and eventually settled to feed over or berley trail.
After protracted views of the TAHITI PETREL we were distracted from
birdwatching by the arrival of a large group of Pantropical Spotted
Dolphin. It was time to begin our return trip so we started the engines
and 10 of the dolphins thrilled us by riding the bow wave for several
minutes. There were other cetaceans present but we were only able to
identify positively 1 False Killer Whale that surfaced several times within
10m of the boat.
Excellent views of a TAHITI PETREL in worn plumage were the highlight of
the days birdwatching, with the FALSE KILLER WHALE and PANTROPICAL SPOTTED
DOLPHINS providing additional excitement.
