Dredging Deception

Surfbreak Protection Society is very concerned about the actual and potential adverse effects that will or are likely to arise if this consent is granted for the proposed activity. This could result in significant adverse affects on the ‘wave environment’ and ‘amenity value of surfing’. The Council is required under policy 16 and 13 of the NZCPS to protect the Spit surf break.
The current inshore sites at Shelley Beach, The Spit and Heywards Point are the first and preferred disposal sites for stage one as stated in the recommendations report (march 2011), with the balance of spoil over 450,000m3 to be disposed at the A0 site. The currently owned dredges are not equipped to travel that far out to sea unless it is calm, as well as the prohibitive cost.
The current statistics for spoil deposited at the Spit site over the last 5 years averages 32,000m3 per year. Reports published in 1998 and 2005 state that the dump site at The Spit is full, with a 43% retention of spoil per annum, and any further dumping would have a direct affect on the wave environment.
This conclusion is ONLY based on the modelling for the A0 site 6.5 k's out to sea, NOT the CUMULATIVE effect of dumping at the current inshore sites. Where very obviously there will be a major effect.

The spoil mound modifies the swell adjusting the peel angle improving the wave to a point, although energy is dissipated from the wave as it passes over the mound. A total absence of the spoil mound still gives a high class surfable wave with a slower peel rate and angle.
Unfortunately the presence of the ebb delta and offshore bathymetry creating the initial wave crest snap is artificially created by the construction of the fixed harbour mouth and mole built in the early 1900's and continual dredging of the harbour.

When is the BIG ONE?
So a major faultline runs pretty much right underneath our house in Waldronville.
Taieri fault lines need research
Otago Daily Times By Eileen Goodwin on Tue, 7 Sep 2010Research was ongoing, but it was now speculated Dunedin's 1974 earthquake was caused by the Green Island fault, rather than the Akatore fault, whichhad not been active for 1000 years, and 2000 before then. read more here
Quaking in our boots: How prepared is Dunedin?
Otago Daily Times By ohno and Kim Dungey on Sat, 18 Sep 2010If earthquakes were as regular as clockwork, then a "big one" of magnitude 8 affecting Otago is 43 years overdue. "There is a 50% chance over the next 50 years that there will be a magnitude 8 earthquake on the alpine fault. read more here
Some facts that we should all be aware of. (source)
• The New Zealand Alpine Fault is one of the world’s most prominent and active fault lines
• The East Coast of the South Island is part of one of the earth’s tectonic plates
• The West Coast of the South Island is part of another plate
• The Southern Alps have grown 20,000 metres over the last 25 million years, but have eroded most of this growth away
• Much of the erosion of the high country ends up on the beaches of our coasts
• The Alpine Fault is due to move in a major way
• All of the above will impact upon us, or our children, and how will we continue to live in the “shaky isles”.

"The New Zealand Alpine fault which stretches 650km from Fiordland to North Westland, is known to have been the host of five events of about Force 8 magnitude where the effects have either been observed or can be measured geologically. The dates that can be provided for past events are circa 1350, 1475, 1615, 1725 and 1826. Using these dates, published in the recent “Hostile Shores” by Dr Bruce McFadgen, the interval between major movements coming forward in time, has been 125 years, 140 years, 110 years, and 101 years. The average gap between major movements over these 660 years has been 119 years. Using this average, another major Alpine Fault movement could have been anticipated in 1945. In other words, we are overdue by some 65 years, although if the longest gap of 140 years is used, we are overdue by only 44 years."
It is generally agreed between geologists from all round New Zealand that a Force 8 event would result in an 8 metre horizontal displacement and a 4 metre vertical displacement along the fault.
So with all this earthquake talk, I came across an interesting video on youtube on the "Expanding Earth" theory. Kind of blows the whole tectonic plate theory out the window.

Dunedin Shark Nets, Stay or Go?
Report on shark nets
Otago Daily Times By Chris Morris on Fri, 11 Feb 2011
Shark nets protecting Dunedin's beaches remain in the sights of at least one Dunedin city councillor. Cr Richard Thomson has called for a staff report on the appropriateness of the nets, including their costs, any possible environmental effect and new scientific knowledge relating to the use of nets.
The report was requested at the end of Wednesday's community development committee meeting. Cr Thomson's move follows an unsuccessful attempt last month by several councillors to have funding for the shark nets removed from the council's draft budget for 2011-12.
Otago Daily Times By Nigel Benson on Sat, 1 Jan 2011
What would we think if the Dunedin City Council paid $36,000 a year to protect us from lightning bolts? We'd think the council was mad, surely?
Yet, the DCC is the only local authority in New Zealand to maintain shark nets.Never mind that there has not been a shark attack in Dunedin waters for nearly 40 years.
And never mind that marine experts, environmentalists and even council staff who oversee the programme say it is nonsensical.

Digging in
So with this post I also took the opportunity to do a bit of a Blackhead quarrying update, I've been taking progress photos for months. The main sequence above is 15months of quarrying and lowering on the south side of the quarry which is the face that is seen from Blackhead Road and the carparks. Heaps of activity and changes, the one big thing is the disappearance of what I call 'the slip' which was clay slide shaped like an arch.

Diploma of Digital Film
One of the assignments for the Diploma of Digital Film at the Southern Institute of Technology. I had to plan, film and edit together a chase scene. Filmed using a Canon 7D and Rode Videomic. Music by Head Like a Hole - Hot Sexy Lusty
Last year I took a few papers studying towards a Diploma of Digital Film with The Southern Institute of Technology. I ended up dropping the screenwriting paper as it was a bit too much of a workload with also working, and struggling with being sick too. It was a real tough squeeze to get the 101 paper finished, but I got there, and managed to get top of my class with an A pass. This year I am taking two more papers, and started last week. The video above is one of my last assignments - Starring Andy Sutherland and Chris Lamb.

Seaweek Beach Cleanup - Brighton
A lady who walked the beach from Waldronville to Ocean view with her dog collected a supermarket bag of rubbish. Me and Jay collected rubbish around the surf lifesaving club and back bank, and along the Otokai Estuary and top domain.

Above: Scott and Caleb collected three very large sacks of rubbish from around the Waldronville area and gun club. And pic below: Sean and his daughters' Edith and Faye collected a large bag from the dunes and beach at Brighton.

I believe a few of the boys from Big Rock collected rubbish along the roadside from Brighton to Kuri Bush this afternoon.

Seaweek Coastal Cleanup 2011
A DCC contractor will deliver two really big wheelie bins to the Brighton Beach carpark at about 9am on Sunday March 6. Collected rubbish can go in the bins, or if there is a lot, it can be stacked within a 2 meter radius of the bins. This will all be taken away by the contractor at or after 1pm the same day. While we still have a central collection point at Hancock Park, St Kilda, rubbish will be going straight into a skip without sorting and weighing as the dirty rubbish cannot be recycled.Sunday March 6th 10am - All welcome to come along and help out.
A group from Big Rock Boardriders will work their way along the coast towards Taieri Mouth to pick up rubbish in the car lay-bys where the freedom campers frequent.
Please meet at 10am by the Skip

Quake Blessings
Jayin and I have a large furnished spare bedroom available if you are displaced by the quake and want to leave the city.
We are in Dunedin, well away from aftershocks.
Please call or text 0274627494 if you are interested or pass on to someone who may need accommodation help.
Sending blessings and energy of support to those affected by the earthquake in Christchurch.
We know of a few friends who have lost their homes, many we have not heard from.
