Brash. Small fragments and roundish nodules; the wreck of other kinds of ice.
Bergy Bits. Pieces, about the size of a cottage, of glacier-ice or of hummocky pack washed clear of snow.
Growlers. Still smaller pieces of sea-ice than the above, greenish in colour, and barely showing above water-level.
Crack. Any sort of fracture or rift in the sea-ice covering.
Lead or Lane. Where a crack opens out to such a width as to be navigable. In the Antarctic it is customary to speak of these as leads, even when frozen over to constitute areas of young ice.
Pools. Any enclosed water areas in the pack, where length and breadth are about equal.
METEOROLOGY
By L. D. A. HUSSEY, B.Sc., (Lond.), Capt. R.G.A.
The meteorological results of the Expedition, when properly worked out and correlated with those from other stations in the southern hemisphere, will be extremely valuable, both for their bearing on the science of meteorology in general, and for their practical and economic applications.
South America is, perhaps, more intimately concerned than any other country, but Australia, New Zealand, and South Africa are all affected by the weather conditions of the Antarctic. Researches are now being carried on which tend to show that the meteorology of the two hemispheres is more interdependent than was hitherto believed, so that a meteorological disturbance in one part of the world makes its presence felt, more or less remotely perhaps, all over the world.
