This is not the Leeuwin Current, which runs down the west coast.  It
must be a current down the east coast.  The Leeuwin Current has
extended past Albany in recent years, with species such as Bridled Tern
now breeding as far east as the Recherche Archipeligo near
Esperance.

The Perth pelagic trip on 2nd August had the lowest water temperatures
for several years.  Back to where they should be.  The
temperature was about 18C, where in the past few years we have still had
up to 22C in early August.  Didn't help with the petrels though with
a very low count, but very high numbers of Yellow-nosed Albatross and
Australasian Gannets.
