Peter,
I may be missing something but can you explain difference (or distances used to
determine) inshore, offshore and pelagic please? Particularly the latter two.
Cheers
Alan

Birds Australia Vic Group Pelagic off Portland, Victoria, Sunday 03 October 2010
Participants: Roy Bryant, Mike Honeyman, Paul Dodd, Ruth Woodrow, Marlene Lyall,
Brian Johnstone, Euan Moore, Patrick Scully, Dirk Tomsa, Wulan Dirgantoro, Dave
Torr & Peter Lansley (organiser and report compiler).
Activity: Aboard the Southern Pride, skippered by Shannon Churchill and Peter
the deckhand. Left Portland harbour at 07:30 eastern daylight time, passing
north of Lawrence Rocks, staying close to the coast for about two nautical miles
before turning south-west to the shelf. Travelled at 11-12 knots reaching the
shelf at 0945 and the first berley point at 10:00 at 38° 41' 03” S, 141° 22' 55”
E.
Berleyed here until 11:35 before moving to our second berley session at 38° 44'
53” S, 141° 26' 20” E where we stayed from 12:00 – 12:55.
A third berley stop was had at 38° 44' 52” S, 141° 28' 42” E, from 13:05 –
13:45, then headed back into port. Cruised down the western side of Lawrence
Rocks then along the east observing the gannetry and other wildlife before
returning to the harbour, docking at 16:30.
Conditions: Virtually calm on departure, then a light NE wind sprung up reaching
moderate strength between 10:00 and 11:00 then moderating to light to very light
in the afternoon. Small amount of spray when turning for home but few
white-caps. Swell was 1 – 2 metres, increasing as we arrived at the shelf break
but soon moderating with the breeze flattening out the waves so that by
afternoon, a small swell of perhaps 0.5 metres, from the south west.
Bright and sunny conditions throughout, some cloud on the horizon developing in
the afternoon. Temperatures mild, 23°C maximum on land.
A very pleasant day with no-one seasick.
Reasonable diversity with 20 species of seabird recorded beyond the harbour
breakwater.
