The two major parts of this region are the Ross Sea and Victoria Land.

Population has ranged 2,000 – 3,000 over the last half century and is currently closer to the lower number.

On the other hand, the amount of krill available makes the Ross Sea a very good whaling location, particularly for the massive blue whales.

While whales were seen in early expeditions, they were not actively hunted until the 1920s when a large number of blue whales were taken.

Other whales present in large numbers are Minke whales and Orca. Ross Island and Erebus Volcanic Province (sometimes referred to as Mc Murdo Volcanic Province.

Mc Murdo Station is located at the end of Hut Point Peninsula at DVDP KI-04. Erebus Volcanic Province The first of four volcanic provinces of this part of Antarctica is called the Erebus Volcanic Province.

There is some confusion as Erebus is combined with the Melbourne Volcanic Province to describe the Mc Murdo Volcanic Group.

The grabens and faults run parallel to the western and NW boundaries of the Ross Sea in line with the long axis of the mountains.

Schematic of Melbourne Volcanic Province showing Mt. Hallett Volcanic Province is at the upper right of the drawing.

The volcano is a large basaltic shield volcano with numerous pyroclastic cones and lava domes, the youngest of which date around 0.8 Ma (Terra Nova). Cape Crozier is the western end of the island and dates between 0.8 – 1.3 Ma. Mount Morning, which will be discussed later is connected via a saddle to the west. Melbourne Volcanic Province The next volcanic group to the south is the Melbourne Volcanic province.

This is where the most recent volcanic rocks from Mount Terror end up. It hosts a telecommunications facility that supports Mc Murdo Station some 40 km away. Unlike the other volcanoes in this region, these are on the land side of the rift and comprise a group of four relatively young stratovolcanoes associated with north to NW-trending grabens and faults in northern Victoria Land.

Its plumbing system is open and stable, in place for as long as the last 17,000 years. It dates between 1.3 – 1.7 Ma and tops out at 3,262 m. Morning is a large shield volcano topped with a 4 m diameter caldera. Morning dates in two pulses, the first between 18.7 – 11.4 Ma, and the second between 6.1 – 0.1 Ma. Major volcanic rocks are phonolites, basalts, and trachytes.
