The answers to this quiz appear in blue below each question.

1. In the upper left-hand corner, the ocean waters exhibit a murky appearance due to a large amount of sediment being discharged from a river mouth. For whom is the river named and what office did this person hold?

The Fitzroy River shown in this image is in Queensland, Australia, and reaches the sea at the town of Rockhampton. It should not be confused with a river of the same name in Western Australia. Queensland's Fitzroy River was named in the mid 1850's in honor of Sir Charles Fitzroy, former Governor of New South Wales and Governor-General of the Australian Colonies.

2. In the upper left-hand quadrant of these images, a small, bright reddish-orange feature is apparent near the coast in both the natural and false-color views. The cause of this reddish-orange feature is:
(A) The recurrence of a bloom of red algae.
(B) An abundance of naturally-occurring iron deposits.
(C) A modern art installation financed by a private consortium.
(D) Waste from a mineral manufacturing and refining process.

Answer: D
The reddish-orange feature is a result of residue ponds at the Boyne Island alumina plant and smelter, south of the town of Gladstone, where raw bauxite from various mines across Australia is digested to produce nearly 5 million tons of aluminum oxide per year. The red color is caused by hydroxides of iron that exist as impurities within the bauxite.

3. A distinctively-shaped, dark-colored reservoir with a sinewy river at one end is located to the south of the aforementioned reddish-orange feature. This reservoir is the main water supply for a nearby industrial and urban region. When these images were acquired, the water level within this reservoir was at about 45% of total capacity. Over the next six months, did the water level in the reservoir rise or fall?

This time of year normally marks the start of the rainy season; however, the water level of Lake Awoonga fell from about 24.5 meters to about 23.5 meters between late November 2001 and late April 2002 due to local drought conditions.

4. A small seaside town within the image area (situated just over halfway down this length of coastline) was named to commemorate the year when a group of global explorers first set foot in this locality. What is the name of the town?

The town of Seventeen-seventy is so named because in May of 1770, Captain James Cook anchored along this part of the coast and made the second onshore visit to Australian soil, and the first venture onto dry land in what is now called Queensland.

5. In the lower right-hand quadrant of these images, a large winding river flows through an agricultural region. Endemic only to the upper reaches of this and a few other nearby rivers is an endangered fish with a peculiar anatomical characteristic. Name the fish.

The Queensland (or Australian) Lungfish (Neoceratodus forsteri) is a representative of an ancient group of fishes that have survived many millions of years and is unusual because of its possession of a single lung. This fish was restricted to the Burnett River (the winding river in the lower right) and to the Mary River, but has recently been successfully reintroduced to a number of other nearby rivers.
