The Plum Island Classic is a little

form from an instability which occurs when the Froude
number in channel flow is large enough. Small scale versions can be
seen in film flow after heavy rain. The files rollwave 1 to 4 were
taken after a rainstorm at Craggaunowen, Co. Clare, in December
2003. The slope is less than
1 in 10, water depth about 5 mm, wavelength perhaps 60 cm, and period
about 1 s. In rollwave
4, Stephen O'Brien's boots for scale.
Atmospheric gravity waves
in the atmosphere are the equivalent of surface waves in
the ocean, and can commonly be seen in intermediate to high level
clouds, as a series of rolls transverse to the wind direction. They
are made visible because, as air rises, it cools, thus forming
clouds. These pictures were taken in Lapland, October 2004.
Pounus and palsas
are peaty hummocks which
form in the far north of Finland (i.e., Lapland). Palsas
mounds which form in flat-lying peat bogs. They (may) arise through an
instability associated with differential frost heave, and afforced by
a vegetative/moisture/radiative feedback.

The Balliol cod fishing trip, 2004
The Balliol cod
is an annual jaunt to the Isle of Wight to catch cod, occasional
conger eel, and frequent dogfish. Here are some pictures from the 2004
expedition. Convening outside Balliol College at 4.30 a.m., we set to
sea at 7.30 as the sun rises, catch the cod, and then repair to
Balliol later that evening for a splendid dinner of cod and accompaniments.
