Eaglehawk Pelagic Trip Report - January 6th, 2019

 

Participants:

Ruth Brozek, Helen Cunningham, Sara Grealy, Rob Hamilton, Mona Loofs-Samorzewski, Andi Magnussen, Paul Newman, Peter Vaughan, Els Wakefield and Paul Brooks (organiser and report compiler)

 

Boat:

The Pauletta, skippered by John Males, with deckhand Michael Males.

 

Notes:

A reasonable trip for diversity and numbers with a couple of good sightings.  A Wedge-tailed Shearwater was a very good record for Eaglehawk and a Soft-plumaged Petrel over 70 fathoms in the afternoon was interesting, but only seen by a one observer.  It was our only Pterodroma petrel for the day.  We had good numbers of storm petrel in the slick and were challenged with good numbers of jaegers; all that were seen/photographed well enough turned out to be Parasitic.

 

Activity:

Left port at 0710 hrs and headed down to the Hippolytes, checking the gannetries there before heading south-east past the shelf-break, pulling up over 270 fathoms at 0915 hrs, drifting NW to 350 fathoms by 1255 hrs.  Headed straight back to port, docking at 1505 hrs.

 

Conditions:

It was partly cloudy and cool when we set out, with a light breeze and a 1.5 m swell.  After we passed the Hippolytes, the south-westerly breeze picked up to 10-15 kn and the swell rose to 2 m with seas of 1 m.  Conditions were similar out wide until ~ 1100 hrs, when the wind dropped back to ~5 kn, the sea flattened, and skies cleared for the remainder of the day.  Water temperature was 17.4 deg C inshore, rising to 18.9 deg C out wide.  None seasick.

 

Mammals:

Brown/Long-nosed Fur Seal: 53 (34) On and around Cheverton Rock and the Hippolytes in the morning.

 

Short-beaked Common Dolphin: c. 35 (5) A few inshore in the morning, remainder offshore in the morning.

 

Fish:

Shortfin Mako Shark: 3 (2) Pelagic.

 

Blue Shark: 1 Pelagic.

 

Tuna sp.: 2 A couple of fish leapt from the water near the boat in pelagic water – probably Southern Bluefin Tuna.

 

Insects:

Yellow Striped Hunter (Austrogomphus guerini): Flew over the back of the boat for a minute or two in offshore water as we motored back to port (55 f).

 

Birds (IOC v 8.1 – max at one time in brackets):

Little Penguin: 3 (3) Offshore in the morning.

 

Wilson’s Storm Petrel: 3 (3) Pelagic.

 

White-faced Storm Petrel: 6 (6) Pelagic.

White-chinned Petrel: 9 (9) Pelagic.

 

WEDGE-TAILED SHEARWATER: 1 A bird was seen by one observer just prior to reaching the shelf-break; either this, or a second bird, made one close pass after we stopped to berley.  Still a very rare bird in Tasmania, but there have now been records off Eaglehawk every Jan/Feb since 2016.

 

Sooty Shearwater: 5 (2) Pelagic.

 

Short-tailed Shearwater: c. 9,900 (c. 1,000) c. 2,400 offshore in the morning; remainder pelagic.  Several thousand birds streamed by in the distance for much of the afternoon – estimated at 200 birds per five minutes; also big flocks passing the boat as we headed back to shore.
