1854: Goldminers stage a rebellion at Ballarat.
It’s that time of year again, when the humpback highway is about to hit peak blubber to blubber as humpback whales migrate up Australia’s east and west coasts from Antarctic waters.
The only frog endemic to the state of Victoria lives in the state’s high-altitude alpine bogs.

The Greenpeace ship MY Arctic Sunrise is moored in front of Humboldt glacier.
A huge iceberg rising 36 metres from the waters of Kane Basin. It is likely that this unusual feature started life as an englacial channel within the Humboldt glacier that it has calved from.
An extreme close up of a section of the middle of the Humboldt glacier, which calves bergs into the Kane Basin.
A polar bear photographed from the deck of the Arctic Sunrise, in drifting and unconsolidated sea ice in Kane Basin, off Cape Clay.
The bear came within 2 metres of the ship, after moving very fast across the ice towards the bow. Sensing food, it sniffed the air and stayed near the ship for nearly 10 minutes before leaving to hunt a seal in the distance. Polar bears cannot survive without sea ice, using it to raise their young, to travel and as a platform for hunting seals – their primary food source.
A view from the Greenpeace ship MY Arctic Sunrise as she leaves her temporary base at Hall Basin opposite the Petermann glacier, due to drifting sea ice, to find her new location further south.
Large tabular icebergs calved into Kane Basin in northern Greenland by the Humboldt glacier, the widest glacier in the northern hemisphere.
Walruses, Odobenus rosmarus, spotted on a patch of broken sea-ice as seen from Arctic Sunrise.
An ice penetrating radar is deployed from a string of kayaks to survey a section of the Petermann glacier.
Three scientists fit a radar transmitter, receiver and antennas to a chain of four kayaks, to obtain valuable data on the processes operating over floating ice shelves.
Glaciologist Dr Richard Bates, of the Scottish Oceans Institute at the University of St. Andrews, takes ‘casts’ of temperature pressure current and salinity on the Petermann glacier.
The ‘ice bridge’ is the southernmost extent of the summer sea ice, which usually extends much further south into the Nares Strait, but has receded dramatically in recent years.

Over the next month, NASA will launch three rockets from the Arnhem Space Centre in the Northern Territory on the Dhupuma Plateau, near Nhulunbuy. The rockets are 13 metre “sounding” rockets that will not reach orbit but will take scientific observations.
Tasmanian devil joeys have successfully bred in a ‘wild scenario’ at Barrington Tops in New South Wales for the second year in a row.
Next time you go diving or snorkelling, have a close look at those wondrously long, bright green ribbons, waving with the ebb and flow of water. They are seagrasses – marine plants which produce flowers, fruit, and seedlings annually, like their land-based relatives.
