Gone Fishing

I am going to take some time out from this blog to try and complete a couple of projects that I’ve started, but am having trouble finishing. So there may be no new posts here for a while.

In the meantime you can subscribe for my irregular email updates here:

And here’s a picture I took of a fisher, a darter cormorant, in Kakadu National Park a few years ago.

Interestingly according to one account of life in the Lower Murray in South Australia one hundred years ago there was a bounty on cormorants (that are closely related to darters), with 34,000 taken in one year ostensibly because they ate too many fish [1].

*********
[1] Travels in Australasia, by Wandandian see page 301

26th July 1909 at Caurnamont, near Mannum

‘Birds were very scarce, though we saw one fine old spoonbill wading round the swamp and swinging his head from side to side in the peculiar fashion these birds have while feeding.

On the latter day, while out shooting, I picked up a freshly decapitated turtle of the kind called by the natives “emys,” and on meeting a fisherman enquired of him whether he had caught many, and why it was without a head.

He replied that the turtles were so destructive of fish spawn, that a scalp fee of one penny was paid on the head of each by the Government, and that he caught a good many from time to time.

On further enquiry, I found that in the past year the South Australian Government had paid over £600 in scalping fees to various people for 116,000 turtles and 34,000 cormorants, thus satisfactorily explaining why the cormorants are so shy, and look upon every man with suspicion; for when one contemplates what a hunting they must have in the course of the year to furnish such an enormous “bag,” it would be decidedly strange if they were at all otherwise. In spite of all this I saw hundreds of them on the Murray and lake waters, so that I am sure many must pour in from outside to take the place of those that are shot, and should this be the case it will be many years before their numbers are at all reduced, or the Government get anything like the full value for their money, or even justify its expenditure.’

[Back then Murray cod were plentiful despite the turtles and the cormorant though now there are no Murray cod in that stretch of river below Lock 1.]

    “is your decelerating SL, a scalar or vector quantity?”

    That’s very funny gav; offhand I’d say a decelerating SL would be a decreasing and wet quantity.

  2. Comment from: spangled drongo


    Wow! didja watch the ABC 7.30 report with our Leigh interviewing Nick Styant-Brown on the Slater and Gordon-Wilson-Gillard slush fund?

    Styant-Brown gave her straight, documented evidence, free from personal opinion, which made it hard for Leigh to infer bias or malice. But her face spoke volumes.

    People have been contacting the ABC over their tardiness in reporting the amazing coincidence of the missing files etc but now Styant-Brown has spoken some shattering truths.

    Gonna be interesting to watch coming events and hard for Julia to dodge the fallout.

  3. Comment from: cohenite


    Yes; it is now clear Gillard doesn’t only lie about CO2; she is a multi-faceted liar; no wonder this country is a mess.

  4. Comment from: gavin


    Reckon Nev can answer with decel definition.

    Btw “SL deceleration” is old hat now so please try to keep up with latest SL info that is not someone’s rehash of old tide gauge records. With out their calibration /maintenance details, nobody can zero even a decade of tide data.

    All those casting stones should be free of sin.

  6. Comment from: Debbie


    Gavin,
    while I agree in principle about casting stones, it has been my observation that most of the stones have been cast in the form of personal attacks.
    One of the worst I have seen is the ‘misogynist’ attack.
    Also, the other side of the coin if people are behaving decently is to accept responsibility for your mistakes, learn from them and also do your best to fix the damage.
    It doesn’t matter if you’re a 3 year old child or you hold the most important position in Australia: bad behaviour is bad behaviour: full stop!

  7. Comment from: Robert


    I agree with the New Testament exhortation not to stone women to death over some nookie, especially if they were young and naive.

    Now, back to the subject of white-collar fraud, white-collar theft, and very dubious professional practice by a partner in a law firm…

  8. Comment from: gavin


    Deb; they don’t last in politics if not able to wear the concrete armor. Nice people have to be hardened because we still live in a wild country where good spin bowlers are hard to find.

    Deb, I suspect you did not see Canberra under fire or the build up a season earlier when arson was the likely cause. Most authorities had a blind side to tinder box conditions where back burning was out of the question after any ignition.

    Did you know besides their CO2 emissions, bushfires are a major source of CO?

  9. Comment from: Debbie


    You suspect wrong Gavin.

    And Gavin,
    You were the one who decided to bring up religious parables….not anyone else…including me.

    You are now doing what Polyaux did earlier in this thread and literally arguing with yourself on this one!!!!

  10. Comment from: cohenite


    Speaking of Canberra does gav endorse Gillard’s version of what she did and knew at Slater and Gordon?

  11. Comment from: Minister for Truth


    What is more interesting is the increasing amount damage being done to Gillards reputation, caused mainly be her own poor judgement, and even poorer ethics.

    Lieing to the pubic about there being no carbon tax, is now underpinned by highly probably fraud, if not professional incompetence, as a practicing lawyer, all wrapped around/involving a cosy cotery of colleagues and crooks, also involved in both the ALP, and the Unions. Appointment being made to high office ir Federal Court, in order shut people up etc.

    What does this say about the ALP’s preselection standards, and the publics gullibility.

    This govt has done more harm to our democracy than any previous govt, Labour or Liberal, and will go down in the history books as the most incompetent of all them.

    Election Please… and Now

  12. Comment from: Neville


    Geezzz Gav fancy linking to the delusional crikey idiots, you’re really scratching the bottom of the bird cage.
    CSIRO modeling has been shown to be wrong before, so I wouldn’t trust them at all on SLR.

    I still say the IPCC has adjusted down every report on SLR estimate since 1990 and the Uni of Colorado estimate is now about 17cm.

    We know you believe in modeling, but I’m very doubtful and would prefer direct measurement and past history against trying to predict the future rate of SLR.

    Meantime everyone who would like to build on the coast should be asked to sign a buyer beware clause before commencement. Let them take their own risk.

    Of course if the PDO remains in cool phase for another decade or so…………….

  13. Comment from: gavin


    Nev; Aaaah, it’s the IPCC estimates decelerating, not rl SL!

  14. Comment from: spangled drongo


    “Aaaah, it’s the IPCC estimates decelerating, not rl SL!”

    Only because that’s what’s happening in the real world:

  15. Comment from: gavin


    Good one SD; your link leads straight back to Church & White and SL reconstruction CSIRO way. Quite happy with that btw. However your graph hardly matches my photography as it comes from in part crudely averaging a handful of tide station records year by year.

    Big tides, storm cells and lots of other natural variation are not given for a reasonable assessment of running means etc used to make sense SL deviation from trend on it’s way up.

    ‘This govt has done more harm to our democracy than any previous govt, Labour or Liberal, and will go down in the history books as the most incompetent of all them.’

    Agree…and I was amused to discover Slater & Gordon have a room named after her, apparently because of her achievements.

    guffaw

  18. Comment from: spangled drongo


    Gav, you can talk yourself into anything. That graph shows less than 2″ SLR in the last 100 years and nothing in the last 60 which ties in with what I am recording at old benchmarks.

    Church and White? Don’t think so.

    “Btw “SL deceleration” is old hat now so please try to keep up with latest SL info that is not someone’s rehash of old tide gauge records.”

    Don’t hand-wave the real thing away. Crap modelling will quickly go out of fashion but empirical measurement is fundamental to the truth.

    Old tide gauge records are the absolute best we can do.

    Trying to measure SLR on a pear-shaped-geoid-with-flat-spots from an altitude-fluctuating satellite is just a dubious exercise in statistics that is full of assumptions as could be seen when Envisat diverged from all the others until their operators reconciled their assumptions.

    Then when you use that “data” to base your predictions on you might as well think of a number and double it.

    It’s Robyn [100 meters] Williams science.

    You would fit in a certain church quite nicely, you speak in tongues!

    WTF are you implying/saying/meaning here?

  21. Comment from: spangled drongo


    “Every headland has a wave shelf just below the tidal zone, every sandy beach has a dune cliff just above the tidal zone”

    Don’t waffle gav, you’re worse than C&W.

    http://www.cmar.csiro.au/sealevel/sl_hist_few_hundred.html

    The tide range at that Port Arthur mark is less than a metre so it’s saying that nothing much has happened there in 170 years which agrees with Sydney. But C&W can make it conform to satellite measurements.

  22. Comment from: Debbie


    Gavin,
    What is your point?
    It’s quite clear that the models re OZ SLR are not matching with real time data.
    You appear to be trying to use normal/natural coastal behaviour to try and prove something else entirely.
    The wave shelves, the sand dunes, the cliffs, the moving estuaries, the rocky outcrops, the caves, the blowholes etc etc etc are all entirely natural features of coastlines and are there because the ocean erodes the coastline and it always has.
    Some places erode faster than others due to the geology/topography of the land.
    It rarely works the other way. . . coastline encroaching on the ocean. . . volcanic areas being a notable exception.
    Coastlines are always in a state of flux, it’s one of the reasons that us humans find them attractive as a habitat.

  23. Comment from: Neville


    Gav what caused the higher SLs and higher temps of the previous Eemian IG and our early holocene? Human population was SFA and zero use of fossil fuels, so the higher temps and higher SLs had to be part of the natural system.
    So what is it you don’t understand about these facts?

    Why don’t all the models show dangerous SLR for the next 300 years? In fact quite the reverse. Greenland is positive but Antarctica or 89% of planet’s ice is negative according to all the models.
    Don’t forget SLs on east coast of OZ were at least 1.5 metres higher 4,000 years ago and had been at this higher level for thousands of years. So what was the cause?

    But why was the early emerging holocene so warm with higher SLs ( than today) after the glacial and where did that higher natural warming come from do you think?

    Why does NOAA’s reconstruction of the PDO show such extreme climate for hundreds of years for both cool and warm phase? Why haven’t we experienced those extremes for the period say 1750 to 2012 for example?
    This period covers all of the IR history.

  24. Comment from: Debbie


    Exactly,
    Other than in the projective modelling which has so far failed to accurately predict and has been continuously lowering predicted estimates. . . .
    In what way is the SL behaviour proven to be ‘unnatural’ ?
    And other than infrastructure works like for example what Noosa does, how would we stabilise ‘natural’ movement and ‘natural’ erosion to protect our heavily populated coastal areas?
    There is no question that they will be subject to erosion, that is a given.
    Even if SL goes down, coastlines will still be changed by the ocean and oceanic tides/weather.

  25. Comment from: Neville


    Bolt asks Swan the right questions. If Blewitt is indeed a crook then why was he a personal friend of Gillard and why did he receive free legal help.

    Ditto her other closer crook friend indeed her then boyfriend who she helped by setting up a slush fund etc? Strange woman indeed. BTW why have this preference for married men with kids? Just add up the numbers and affairs.

    http://blogs.news.com.au/heraldsun/andrewbolt/index.php/heraldsun/comments/awu_strange_company_and_swans_strange_defence/#commentsmore

    She has since turned on another personal Greek friend who she called a greek bull s…t artist and now refuses to even answer his emails.

    But how did this clueless fool ever become PM of OZ. You could pick any average aussie woman off the street and they would do a better job.
    They certainly couldn’t be as hopeless as Gillard.

  26. Comment from: gavin


    Guys; lets take advantage of an excellent photo essay so I can explain some wisdom re headlands SL etc. beginning with a familiar wave cut shelf below a famous cliff at Fossil Bluff NW Tasmania.

    http://www.flickr.com/photos/58828131@N07/5625252503/in/photostream/

    This shot depicts the shelf in the tidal zone and beach head beside the crumbling bluff. To the far left and east of the river mouth is and old crumbling breakwater sheltering a small harbor, another platform cliff face and so on right along the coast in either direction.

    But this is Bass Strait where SL has been slightly both higher and much lower in recent geological times. I say there are few wave cut benches around the + 1.2 or something m high SL and I was told by our landlord a self taught field naturalist, the higher sea level was merely the overshoot from a rapid rise.

    On the property about six miles inland were several mudstone fossil deposits that escaped notoriety until we had shell specimens examined by the museum in Hobart. They were a different age to Fossil Bluff but also much older than our historic SL variations.

    Where the sea was millions of years ago is of little importance to current life forms but it is worth guessing what caused each major prehistoric climate/SL upset. Any good physics should show us the prime culprit is the composition of our atmosphere including those times when continents split or plates collide, thus allowing for more or less volcanic muck up there.

  29. Comment from: Neville


    New study shows that SLs have been declining around OZ for 7,000 years since the holocene optimum.
    Estimate is that SL was 1 to 2.5m higher during that period.

  30. Comment from: spangled drongo


    Gav, sorry but that doesn’t tell us anything about current SLR and where it is heading. Even something as simple as this tells us that seas, while they rise and fall somewhat, are remarkably steady and stable over centuries.

    When cities like London have been used continuously as ports for a couple of millenia without any remarkable SLR problems through periods of well documented climate change both warmer and cooler than we now have, says it all:

    “Any good physics should show us the prime culprit is the composition of our atmosphere”

    No; SL is determined by how much water is stored as ice.

  32. Comment from: Neville


    It’s a pity only Steven Goddard is showing this quote from Hansen. If it’s true then there should be a full inquiry and court action to sort out this mess.

    http://stevengoddard.wordpress.com/2012/11/18/nasa-rewriting-us-history/

    How can a team of activists be allowed to change and distort the so called highest quality and most accurate temp record on the planet?

    But we all have to suffer the consequences for their lies and criminality. If that quote is correct then why hasn’t this become the biggest story in modern journalism?

  33. Comment from: Neville


    Sorry it is definitely a genuine quote and here it is from Hansen through NASA giss in 1999.

    http://www.giss.nasa.gov/research/briefs/hansen_07/ How can the so called best temp record on the planet be so at odds with fairly awful, dubious data from around the globe but then changed to suit leftwing activists?

    So why has the record been changed in just the last decade. This should be the story of the century but we hear not barely a whimper.

  34. Comment from: Johnathan Wilkes


    Neville

    I work with records all day, that is why I was so incensed about manipulating past temperature records.

    If one must do it OK, but for God’s sake keep the original intact!
    What if you get it wrong and no original?
    How can you make amends? The way it looks now, nobody really knows anymore what really happened in the past.
    It’s criminal what they are doing, that what it is.

    gav showed us some nice pictures, but what were these these pictures meant to prove?

  35. Comment from: Neville


    I agree with you JW, but thanks again to John Daly for keeping the earlier record.

    BTW Humlum has a Greenland temp record for the last 8,000. Much warmer than today, in fact we are definitely at the cooler end of the holocene.

    http://climate4you.com/ I find it hard to directly link to the graph but it can be found at left under climate history.
    But it makes you wonder what the fuss is about.

  36. Comment from: Debbie


    Dunno Gavin,
    maybe the atmosphere thinks the ocean is the prime culprit?
    There are a myriad of ‘physics’ involved in the very complex relationships between the oceans and the atmosphere.
    With respect, your statement above is rather simplistic and is really only a statement of faith, not a settled scientific fact.
    So far, neither the ocean or the atmosphere appears to be taking too much notice of ACO2 on a GLOBAL(bold) scale in relation to the SL modelling.

  37. Comment from: spangled drongo


    The agony of ABC Insiders [both their own and the viewer's] when they are trying to reassure each other that the PM has nothing to answer for [we..ell, maybe one or two little things] with this large muddy elephant sitting in their laps.

    el gordo, et al,

    ‘This govt has done more harm to our democracy than any previous govt, Labour or Liberal, and will go down in the history books as the most incompetent of all them.’

    I hope you are only talking Federally. The last TWO brands in NSW, ( Newcastle Sydney Wollongong ),
    Take the absolute top prize for that. AND with no objections from any local time wasting party liners.
    Water, water , Govt departments , roads, bridges, you name it. Nest egg building traitors.

  39. Comment from: el gordo


    Federally.

    In NSW the people gave O’Farrell a mandate and on the Central Tablelands where I live the combined votes of farmers, graziers, small business and miners went towards the Nats in large number.

  40. Comment from: Minister for Truth


    Yes Ian T, I was only referring to the Federal arena …and thats bad enough.

    Having spent another evening with friends at dinner it would be no surprise at what the dominant topic of conversation was, namely the despair at what this incompetent Gillard Labor Govt is doing to our country, it was palpable.

    The good stuff was the discussion as to what we should be doing to lift us up again and become more efficient, productive and fair and risk takers.

    Frequent comment to effect that we should quit the ridiculous UN treaties, and more so the ones dealing with migration and refugees. How is it that many of the refugees ( illegal immigrants) are from failed and oppressive islamic states in the ME and North Africa, but they pass through the more enlightened Malaysia and Indonesia which are also Islamic states, to get here. Further where do these people get the money from to pay for the air fares in the first place….any bets on various well funded Islamic charity’s anyone.

    They are blatantly country shopping, and we are being played for suckers…all in the cause of exanding the ummah. We are basically importing our own future fifth columnists, who are out breeding us as in Europe ..and quite deliberately so.( “We will use thle bellys of our women to become dominant, Islam will and must prevail”)

    …..and then there was the mining industry and how these clowns have screwed the whole game.

    see Maurice Newmans excellent piece of a few weeks ago

    …another area was the need to get a review of how universities operate with minimal apparent external scrutiny, and compliance with standards common place in business, and how inefficient research funding systems are. No problem with having researchers properly funded for longer periods providing there was proper accountability

    …then we ran out red.

  41. Comment from: gavin


    no not coh, “SL is determined by how much water is stored as ice”

    Ice is determined by climate, climate is determined by atmosphere and atmosphere is determined by it”s gaseous composition thus acting as an asymmetric filter to radiated energy from opposite directions

    http://atoc.colorado.edu/~whan/ATOC4800_5000/Materials/Milne09.pdf

  42. Comment from: spangled drongo


    Climate is not determined by atmosphere.

    It is our water mass on earth that gives us our bullet-proof climate and ice is a big part of that.

    The mass of water on earth compared with atmosphere is at least 50:1

    It just sucks up any temperature extremes and spits out normality.

  43. Comment from: spangled drongo


    That link of yours gav is the usual alarmist/modelling wish list detritus.

    Absolutely real-world-evidence-free.

    When are you going to produce some facts?

    When are you going to look out the window?

  44. Comment from: Neville


    Well Gav good to see that study mentions the IPCC latest estimate for SLR with a mid range of 30cm to 2100 in AR4 report.
    UNI Colorado and Humlum now state 17cm.

    Interesting they mention the much higher temps and SLs and much faster SLR in the earlier holocene and previous eemian IG.

    But I’ll let Cohenite answer your statement.

  45. Comment from: spangled drongo


    Actually I understated the ocean/atmo’s energy capacity above by 8,000%.

    It is actually 4,000:1, not 50:1.

    http://noconsensus.files.wordpress.com/2011/04/image2.png

    That is why a tiny fraction of the atmo [ACO2] has absolutely no chance of producing CAGW.

  46. Comment from: cohenite


    “But I’ll let Cohenite answer your statement.”

    What statement Nev? gav doesn’t make statements. Still, I see he has provided a link which is remotely relevant; the abstract says:

    “This tenfold increase in the rate of rise can be attributed to climate change through the melting of land ice and the thermal expansion of ocean water”

    Land ice is not melting; the bulk of land ice is in fact increasing with the Antarctic land ice increasing; the historically normal Arctic melt does not effect SL.

    The thermal content of the oceans is not increasing either;

    http://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/heat_content55-07.png

    OHC has basically not increased since 2003 when ARGO was introduced and measurment before then was highly flawed.

    SST has also decreased since 2003 but that has not stopped AGW advocates lying about it most recently with cyclone Sandy.

    Gav should do some research on Milankovitch Cycles and Glaciation and entertain us with some facts for a change.

  47. Comment from: el gordo


    Gav’s link to Adams et al.

    ‘According to the marine records, the Eemian interglacial ended with a rapid cooling event about 110,000 years ago (e.g., Imbrie et al., 1984; Martinson et al., 1987), which also shows up in ice cores and pollen records from across Eurasia. From a relatively high resolution core in the North Atlantic. Adkins et al. (1997) suggested that the final cooling event took less than 400 years, and it might have been much more rapid.

    ‘Following the end of the Eemian, a large number of other sudden changes and short-term warm and cold alternations have been recognized; apparently many or all of these occurred on a global or at least a regional scale.’

    Are we there yet?

  48. Comment from: el gordo


    Methinkso….

    Abstract from Sancetta et al.

    ‘In North Atlantic deep-sea core V23-82, changing surface water conditions are revealed by changing composition of fauna and flora. Sedimentation rate seems to vary little so that approximate dating of climatic events within the X zone of Ericson is possible.

    ‘These include an interglacial temperature maximum at 124,000 YBP; start of the post-Eemian cooling at about 116,000 YBP; and peak cool conditions at about 110,000 YBP, followed by warming.Drop in summer and winter temperatures about two-thirds of the way towards full glacial values and a significant drop of salinity is suggested by quantitative paleoenvironmental analysis of the 110,000 YBP cold episode.

    ‘If the Eemian is taken as the analog of the present interglacial, a point in time 116,000 YBP becomes the historical model for today’s ocean, and the North Atlantic is now approaching a time of severe cooling.’
