What I have observed was this erosion is not as simple as many sea level rise models might suggest. In particular I had not noticed so much erosion at the pathways leading down to the beach. This suggested the ocean was not advancing a fast as many fear, There was erosion, but it would be just one of the 5 “official” paths at a time that would show erosion at the base of the path. This along with other observations suggested to me that the erosion was mainly localised at any given time. This year has seen more significant events but they still seem somewhat localised.</p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhl_NqzroqNAYIRXO-QovJNwe2C96KbIja6TK5bueQ1z5Zz1k3-FUOTlv4N_5PjFfF3TGIwLF5mzlzjG019hE6RsN_9OOBXOF03iAki9igkQ0sN5Qf1vvUVBUseaIsUIbgbz2a7EI_P6Jk/s1600-h/_IGP6745-001%25255B3%25255D.jpg"><img title="Erosion Scarp at the bottom of teh Beach One Ramp" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; float: left; padding-top: 0px; padding-left: 0px; margin: 0px 10px 0px 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="Erosion Scarp at the bottom of teh Beach One Ramp" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgGSXdVBPwzYbkkpV0Lz_VxZZOTHQnMzZzdlosDkzuJoIzGw-ABo0n8CDszeAjkdmOz49DtHDbJWEd8t3BevbXC7ZHxcm3B-QumY37vvzF8Qou5hoOoC9fZATjq0_XqdavdFPtE4umUvzk/?imgmax=800" width="244" align="left" height="244"></a>At the moment there is a very big “step” at the bottom of the beach one ramp (about 1.2m), where recent high tides have washed deep back into the dunes and also the revegetation fencing and drainage pit. Again there is ample evidence to suggest that the amount of erosion is more localised, rather than generally along the beach. Although this years king tides (around the time of full moons) and strong swells have lead to more erosion scarps along much of the coast than over the past couple of years.</p> <p>The super moon term has caught the public’s imagination, but I strongly doubt it alone is responsible for a super tide. The moon was however a full moon and it occurred as the moon is closest to the earth, so there will be a contribution. The real culprits are combination of three additional things. Strong swells associated with a significant storm front last Tuesday (often this is referred to as a storm surge) The low air pressure associated with the storm which crossed the coast at Venus Bay just on sunset. Finally the presence of deep gutter (rip area) just south of beach one ramp (see photo below) which focused the wave action at a small semi-circular area in front of the ramp.</p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh4e-UIXWWwu1gzjj-ol2QbY0FYkNCZs24RGVnASJUOyTMrhVHERg3P8R4BIcqq9qfRQmfHRjcLj1TzZlwAnJYlmgTdHJoQY4sJjnsYVlr_Dr8UxMz9yKc-WTJ092n-3jxoV6E3xKLYtIE/s1600-h/image%25255B9%25255D.png"><img title="View out to sea from Beach One Ramp showing positiopn of gutter" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="View out to sea from Beach One Ramp showing positiopn of gutter" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjxDmI265YAkLBnh0zYsbHUvvuhB8sfRl82UpjBh_OvqEyoQCevmTFdH5OHADGeeOB_NhPNSjK0CK2jaG_dLfznP25Ndq8Enq-SKcgFre4KrP0gKDtFNiuCGe-qbd47Zke9MF1UyhE4blY/?imgmax=800" width="464" height="182"></a></p> Anonymoushttp://www.blogger.com/profile/11584527150777453734noreply@blogger.com0tag:blogger.com,1999:blog-5509163535387999688.post-46229285602830885532014-01-19T22:29:00.002-08:002014-01-19T22:29:46.144-08:00Wedgies and Wide beaches<div class="separator" style="clear: both; text-align: center;">

<span style="font-size: large;">T</span>he recent King Tides have contributed to some fore-dune erosion at Beach One, exacerbated by the wide and mostly flat beach summer berm profile. <br />
<br />
Meanwhile at Point Smythe a pair of Wedge-tailed Eagles <i>Aquila audax</i> were observed patrolling at a very low altitude for birds with such keen eye-sight. Their sustenance consists predominantly of carrion, but rabbits, some marsupials and other birds can feature in their diet.<br />
These two birds are more than 5+ years old, as attested by their dark colour. Younger birds are browner, progressively turning towards black as they age. In this photo the larger sized female is below her male.<br />

Most of those coming along the beach at Venus Bay are returning to rockeries in Phillip Island, but there is also a big colony at Port Fairy. It is not uncommon for many of the birds to die of exhaustion during the migration, which leads to the phenomenon known as a <strong><em>shearwater wreck</em></strong>, where large numbers of dead birds are washed up on the beach. <br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7E_EKNvVRd8sSl8P3PIIyUXeVo683IefW3Hcty1yk_Tf6_upTJp6xg6lwcVibAV-xg4rK-U-064BUpypAqIru0S8EBjlROhIYhtt_Szi1LWH25u6vRVj5xQU2VS3avENMqfirwyy9Ov8/s1600-h/clip_image001%25255B6%25255D.jpg"><img alt="clip_image001" border="0" height="238" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjy4WFA5hDvR9gPPbUnCixKzqI9WGmwONls_OzmcL2OMnXVIMM9VHaxR_jDQdItmUue8vyy9-Xtn9tjd8DrcFdD2CLn77NLooVMO_djNM3gMOF-7x01NvJUU-MnX139cd5ngZ03xVVMDJA/?imgmax=800" style="background-image: none; border-bottom: 0px; border-left: 0px; border-right: 0px; border-top: 0px; display: inline; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="clip_image001" width="464" /></a><br />
<b>A CALL FOR INFORMATION</b> <br />
The wreck of Short-tailed Shearwaters appears particularly abundant along the Australian coast this spring. The number of dead shearwaters lining the beaches seems to be higher and more widespread across the Australian coast, but unless we collect data and do this consistently, this is only an observation. With shearwaters representing the most globally abundant avian species, it becomes important to understand just how many die each season and what this means to overall numbers. <br />
We would like to make a start toward greater understanding and to learn more about this year’s wreck in particular. It has been suggested that changes in food availability due to the warming of the oceans is taking its toll on these migratory seabirds. <br />
As regular beach visitors, you can play a role in helping us learn more about this issue. Over time we can learn whether mortality rates vary from year to year and if these trends are consistent, and/or linked with any particular climatic events or food availability. <br />
When you next take a walk on a beach (albeit to look for breeding resident shorebirds!), please record: date, time, beach name, location, distance walked (ideally the latitude and longitude of your starting and finishing point), number of dead and dying shearwaters. <br />

Bidgee-Widgee (<i>Acaena novae-zelandiae</i>) is a native ground-cover of Australia and New Zealand which is endemic to the Point Smythe area.</div>
<div class="separator" style="clear: both; text-align: left;">
It is through the burrs produced in Summer which attach to socks, pants or shoelaces that most people realise they have had an interaction with Bidgee-Widgee, unwittingly drafted as agents of seed dispersal. Each seed has four spines which terminate in minute barbs that hook onto clothing or animal hair, similar plants overseas inspired the invention of hook & loop fasteners like Velcro.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
It does play an important role in soil binding and erosion control, and is tolerant of a wide range of conditions from shade to full sun, wet to dry soils, making it worthy of consideration for the local home garden. So the next time Bidgee-Widgee covers your socks in burrs, look on the bright side that your socks have become a free packet of seed!</div>

During the sweltering heatwave afflicting most of southern Australia this week, one could be excused for thinking that all animals suffer as we do in the heat. Ectothermic (cold blooded) animals however have a metabolism that works much more efficiently at temperatures that would risk heat-stroke for any bird or mammal species, including us. Often considered as "primitive lifeforms" it is only by observations during hot weather that this misconception can be challenged. </div>

All the signs that Spring has arrived in Venus Bay abound. The melodious calls of birds proclaiming territory and breeding rights fill the bush, and one of the most musical is the Golden Whistler <em>Pachycephala pectoralis </em>is hard for your ears to miss. (Male pictured above, females are duller and lack the black & white head markings).<br />

The plants are also getting into the mood, with many beginning their flowering. The Running Postman <em>Kennedia prostrata</em> (above) delivers a crimson treat with its pea-like blooms.

Sand is progressively moving deeper into the inlet and this hinders the development of mangroves, which are really the only way to slow down eroding the shores. The open “beaches” allow waves to undercut the peat layer of the salt marshes and once compromised like this the salt marshes quickly wash away. Trees offer only slightly more resistance but they soon also succumb to the erosion.</p> normhttp://www.blogger.com/profile/03064736990200219176noreply@blogger.com0tag:blogger.com,1999:blog-5509163535387999688.post-86818766420593567742012-06-19T18:07:00.001-07:002012-06-19T23:37:58.875-07:00Did the earth move for you?<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjLeytbMFtDiNazNRc9qjx_ZZekIXFAkyM3-5Z2j0H9xJM0qXIHAbSESQ_GVzXocGUuEfPAt8jA6ZuIrOwRBnW7CuhZBRCueUx6zo94sSGKJHoF8kZHdlQwt1frPOyX2VRmzHZUIHLEqPE/s1600-h/alvin%252520earth%25255B3%25255D.jpg"><img align="right" alt="alvin earth" border="0" height="220" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjcaGpcikRL5HmPRk0u7svLqqxtss5K6wEygwmLnJUGUKYIgMCLsEmUeMWcyhCOTj_E87_1Xr5dtY4kssp3dx0ZkZev-QZN22qqtJZQ0fjoMqz6oCuS-ERbBnYhELHoPBewpbUD10PBkq8/?imgmax=800" style="background-image: none; border-bottom: 0px; border-left: 0px; border-right: 0px; border-top: 0px; display: inline; float: right; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="alvin earth" width="305" /></a>Last nights <a href="http://www.ga.gov.au/earthquakes/getQuakeShakeDamage.do?quakeId=3225984">earthquake between Moe & Mirboo North</a>, best estimates at the moment a 5.4 Magnitude at 8:54PM, gave the folk in Melbourne a good shaking, but how was it felt at Venus Bay?<br />

Perfect conditions for a really high tide. I did check the beach on the 7th. and could only see the old erosion face from last year and the regrowth on the sand screen below them. There was a slight notch in several location that looked as if it could be more than a few days old but it was not very extensive (these are labeled in white in the above photo). I revisited the same areas south of beach one today and can see a fresh cut (only 5 to 20cm tall) but extending most of the way along the beach (labeled in yellow). Also the beach below the cut does seem to be “steeper”. So I suspect there has been some significant erosion/sand movement along the beach in the past week. So the picture that the erosion events are most likely to occur with the king tides (full moon) and atmospheric lows does have a little more circumstantial support.</p> normhttp://www.blogger.com/profile/03064736990200219176noreply@blogger.com0tag:blogger.com,1999:blog-5509163535387999688.post-71014349145994444302012-06-09T19:02:00.001-07:002012-06-09T23:27:56.621-07:00Venus Bay Inspired Art<h3>

The ochre coloured sandstone [1] was at one time a thriving beach, brimming with life and specifically a prolific population of <i>Donax <a href="http://en.wikipedia.org/wiki/Donacidae">Deltiodes,</a></i> also known as Pipis or Surf clams. However the Pipis were so yummy and they were harvested in such numbers that fewer and fewer shells reached maturity each year. Then suddenly in one season, the entire population failed to reproduce. Worse the rich food chain of the beautiful beach collapsed, with their demise, and the once thriving beach became a pale version of itself. Only a few brave worm burrows [2] could be found. Then all signs of life disappeared [3]. <br />

The work was created first as a mould of the main units in the sand south of Beach one. This included leaving some of the worm burrow/air holes undisturbed. broken Pipis and other shells where collected nearby and scattered in the mould. The mould was filled with expanding polyurethane foam and cover with the canvas, burried and left to harden for an hour or so. The foam on canvas mould was next painted with several coats of sand, gesso and latex to create an absorbent sandstone like finish. Finally this was “stained” and painted with various oxides. It represents a future geological rock face, perhaps a few million years into our future. This rock face runs close to the bedding planes with the oldest layers, the ochre sandstone on the lower left, closest to you. You are looking "up" in time.<br />

Remember you must not look directly at the sun <strong>SERIOUS EYE DAMAGE MAY RESULT. </strong><br />
The transits of Venus, they are like an eclipses, are very rare but when they occur there are two such events 8 years apart. During the transit Venus is positioned between us and the sun and casts a shadow. Unlike an eclipse of the moon this show is small and seen as a small dark dot as it moves across the face of the sun.<br />
This is only the fifth transit since <a href="http://www.joe-cali.com/eclipses/PLANNING/ToV2012p/2012TransitOfVenus.html">James Cook travelled to Tahitti in 1769 to make observation there</a>. Astronomers back in England wanted to know exactly how long the transit took and from that they predicted they would be able to compute the distance of the earth and Venus from the sun. This trip is also famous because on the way back to England he reach Australia, called it New South Wales and claimed it for England. <br />
<h3>
When?</h3>
There are four key events in the transit<br />

<h3>
Where is the best place to observe?</h3>
Well really anywhere around Venus Bay you can see the sun at the times above. Remember the sun will be relatively low in the sky during the Ingress. So I might start my own observations just near lees Road and Jupiter avenue intersection, on the bike track as it comes off the little rise. There is a very clear view of the eastern sky from here. During the Egress the car park at Beach One is a good location as it has a good view of the north western sky.<br />

<h3>
How to Observe?</h3>
I will be using the same method used by captain cook. I will project an image of the sun onto a screen using my telescope. I took the picture below of the transit in 2004 and I’m hoping I can do better this time.<br />

Sometime you are confronted by the site of dead birds, like the <a href="http://vboping.blogspot.com/2012/01/coastal-walk-report.html">albatross below</a>, penguins, seals, dolphins and even whale. Unfortunately such deaths happen, frequently related to storms at sea. If you come across such birds, particularly penguins, it is a good idea to check for leg bands, its is import to note which leg is banded and the order of colours and any letters or numbers. Also if the cause of death is clearly not natural (eg the bird, fish is tangled in a net, line) they probably should be recorded. We don't need to be forensic experts or act as" the wildlife police", but significant changes in our environment may be signaled by other species. <div><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpZ4EmndyVqxMAx5msjFsH99XX6emAsdNmnHJlr-avMSDD5_DnhGOhx22scxUOU3uGiHFpeNv0qa3zNSJX0D3VyqFWBDQu-19lTCacPCa5FyWnN6xIAXz7ovmVXliEF6_yq6gHUkh1FNo/s400/dolphin.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5701009210851441346" style="cursor: pointer; width: 440px; " /></div><div>Even Natural deaths when in larger numbers are worth recorded, for example our site was probably the<a href="http://vboping.blogspot.com/2010/10/migration-mishap.html"> first to note the large number of mutton birds that died</a> and washed up in beaches all along Australian beach last year.<div><br /></div><div>BUT please inspect these animals and birds with respect, a very rare and endangered species may need to be the subject or further scientific study.</div></div>VBOPhttp://www.blogger.com/profile/02142786080161686930noreply@blogger.com0tag:blogger.com,1999:blog-5509163535387999688.post-9284768125556147612012-01-22T17:14:00.001-08:002012-01-22T17:24:38.082-08:00VBOPing on Google+<a href="https://ssl.gstatic.com/images/icons/gplus-64.png"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 64px; height: 64px;" src="https://ssl.gstatic.com/images/icons/gplus-64.png" border="0" alt="" /></a><br /><a href="https://plus.google.com/u/0/105445912810857683611/about">VBOPing</a> is now on Google+, not fully sure how we can us all the facilities of google+ but if you are on Google+ start following and watch for share circles and links.

The Average Height Tide Line is 10 to 20 meters seaward from these scarps, which has meant that the flatten out upper part of the beach (the <a href="http://vboping.blogspot.com/search/label/summer%20berm">summer berm</a>) has been able to be strongly developed along the beach. This an area where dried out seaweed and other beach debris can accumulate. the sand dries out and is more susceptible to wind erosion so this part of the beach is flatter.

Hopefully they are enjoying this summer on the beach.</p> <p>BTW its the W<a href="http://vboping.blogspot.com/2012/01/point-symthe-geology-walk-to-inlet.html">alk out on Point Smythe</a> TODAY!</p> normhttp://www.blogger.com/profile/03064736990200219176noreply@blogger.com0tag:blogger.com,1999:blog-5509163535387999688.post-36165699293365915032012-01-16T21:38:00.001-08:002012-01-16T21:42:21.587-08:00Point Symthe – Geology walk to Inlet & Ocean Beaches<a href="http://lh4.ggpht.com/-oJZvtBy9jKk/TxUJacsJmqI/AAAAAAAARnM/QtUEvWOHO28/s1600-h/soldier%252520crab%25255B3%25255D.jpg"><img align="right" alt="soldier crab" border="0" height="129" src="http://lh6.ggpht.com/--35Y-N0trGI/TxUJbEboFCI/AAAAAAAARnU/VfDymbNOPXA/soldier%252520crab_thumb%25255B1%25255D.jpg?imgmax=800" style="background-image: none; border-bottom-width: 0px; border-left-width: 0px; border-right-width: 0px; border-top-width: 0px; display: inline; float: right; padding-left: 0px; padding-right: 0px; padding-top: 0px;" title="soldier crab" width="219" /></a>You will find this years geology walk out on <a href="http://parkweb.vic.gov.au/explore/parks/cape-liptrap-coastal-park/things-to-do/point-smythe">Point Smythe area</a> (not to Point Smythe itself) in the <a href="http://www.dse.vic.gov.au/coasts-and-marine/coasts/coastcare/summer-by-the-sea-home">Summer by the Sea program</a> list under <strong>Geology Rocks!. </strong>Sorry no rocks to see but plenty else, including geological processes in action. Perhaps a few experiments on the beach. The route this years has been trimmed (no big dunes to walk up) and there is still plenty to see, in less than 5km. <br />
