Deltas are one of the nicest coastal features to spot from the air, especially when viewing a false colour satellite image as below. This is the Lena delta, where the Lena river discharges in the Black Sea.

Transgressive dunes
I mentioned at the end of last week's lecture the formation of transgressive dunes, which are large unvegetated coastal dunes that migrate landward. They widely occur in Australia, and were also common along the French Atlantic coast, until Napoleon planted pine trees to fix them (this area is known as 'Les Landes'). Some of these French Atlantic coast transgressive dunes, however, remained and the best example is Pyla dune just south of the Arcachon Inlet near Bordeaux.

Tropical cyclone map
I am reading up on tropical cyclones for a review paper on effect of extreme storms on shorelines and came across this fantastic picture showing 150 year of cylone tracks. Couldn't resist! The cyclone tracks are subdivided into tropical depressions, tropical storms and hurricanes (Category 1-5), reflecting increasing intensity. Why do you think there are no hurricanes around the equator? Also, note the lone tropical storm along the coast of Brasil. For more information click this link.

Rip currents on beaches
Welcome back and happy new Year. Next lecture is on beaches and we will spend a little bit of time talking about rip currents. Have a look at the following two utube clips to get excited: Dr Rip's clip and BBC Bang Goes the Theory.

Pleistocene barriers in Australia

The location is the Coorong coastal plain, on the border of South Australia and Victoria. What is unique about this site is that the whole region is subjected to a very slow rate of uplift so the highstand barriers form a kind of staircase, with the oldest one (the one furthest inland) elevated most.
In addition to the contemporary Holocene barrier system, there are 12 Pleistocene highstand barrier systems, each mapped in the map to the right. The oldest system is at least 860,000 years old and has been uplifted by 58 m since its formation. from this, the rate of uplift can be computed: 58 m divided by 860,000 years = 0.07 mm per year.
