Bird Observation and Conservation (BOCA) PELAGIC TRIP off EAGLEHAWK NECK, Tas, Sunday 18th September 2011

OBSERVERS: Rohan Clarke (organiser/report compiler), John McRae, Ruth Brozek, Dejan Stojanovic, Els Wakefield, JJ Harrison, Paul Brooks, Marlene Lyell, Geoff Bromfield, Mike Honeyman, John Young, Mark Stanley.

WEATHER: Reasonably calm inshore, 5-10 knots with occasional gusts to 15 knots in offshore and pelagic waters in the AM. Moderating around midday to ~5 knots. Mostly clear skies with brief periods of high hazy cloud around midday. Good to excellent visibility. Mild.

SEA: Reasonably calm through inshore waters with first real swell felt just beyond the Hipploytes. In offshore and pelagic waters a 0.5-1 m sea on a 2 m south-easterly swell with occasional larger sets to 3 m. A comfortable ride throughout the day with almost no spray or splash. Around midday conditions moderated (swell 1-2 m). No-one seasick. Compared with Portland, the weekend prior, this was a very pleasant day at sea.

ACTIVITY: Sailed at 0725 EST. Headed out past the Hipployte rock stack before proceeding to the shelf which we crossed at 0910. Surprisingly few birds at the Hippolytes and generally low numbers of albatross all the way to the shelf. Good numbers of Common Diving Petrels in offshore waters. Our first stop at 43º16.66’S 148º16.42’E over 500+ fathoms of water were we berleyed with fish discards and chicken skin. Moved further north and further out to 43º04.00’S 148º19.29’E over 500+ fathoms for a second berley stop. The last stop of the day was back on the shelf edge (43º00.91’S 148º15.04’E ~100 fathoms) where we met a passing trawler that produced the highest counts of albatross for the day. Headed back in at 13:45, docking at around 1520.
