October melt, Chicks and Preparation of Visitors

Caution, this edition does contain photos, of the harsh reality that the unforgiving Antarctic elements have upon their extroadinary residents - The Emperor Penguins.

October already, did i miss September? The hours, days and past few weeks have all merged into a pattern of "blink and you'll miss it", scenarios. The clock is ticking, and the race is on to get the base inorder, before our new guests and arrivals get here at the begginning of November - weather permitting. Base in order - well, the reality of releasing the grip on our winter slumber and the shock of relief, again. Its been eight and a half months since all 18 of us saw another human being, a period thats about to come to an end.

With the hussle and bustle of new summer jobs to do, one of the first was a shopping spree to the container line to retreive some brand new skidoos for Matt, the vehicle mechanic to assemble, service and get up and running for the summer crew.



The oncoming of November also bought new weather - "Dingle" days, perfect for Ozone hole observations, and Blimp flying.

The Blimp, tucked up, happily snug in its weather haven, in readiness for the call up to fly.



Alex, the data manager, helping me, get the Blimp out of its slumber, which is a feat in itself.



Dave and Kirsty, the Met Babes, strapping the Meteorological instruments to the blimp lines, to aid in ozone observations, wind speed and direction, temperature, moisture and pressure readings.



The ozone instrument on the left and the wind speed and direction, temperature, moisture and pressure instruments on the right.



Me, using the winch to release the blimp, which is filled with helium, to a height of about 200 metres.



Dave, blimp and the Meteorological instruments in flight.



Lowering the blimp back to bed.



With a push and a shove.



Along with the surprising good weather and "Warm" sunshine, came the melt, a sure sign summer is well on its way, with a temperature of minus 10 degs. Made even more real by the sightings of several Antarctic petrols flying over base, during the blimp flight a few days before.



As the summer fast approaches, many digging jobs are there for the taking, or like below, a chance for Dave to show off his heroic ness of conquering a small snow drift. With his heroic ness in vain and of no use to any "Fancy Free" young ladies walking by, (cos there weren't any) all his testosterone, was tested on digging out the tracks of the two Snowcats.



Me, giving Dave and Matt a helping hand.



Matt, switching on the Webasto in the Snowcat, which is a water heater that preheats the engine prior to turning the engine over.



Steam coming from the melting ice inside the engine hood.



The influx of good weather made no excuses for any outdoor labour to go astray. One of the major digging jobs, was digging out the power cable running from the Laws to the garage, which are attached to several 10 feet long beans, which have clearly become very buried.



A few days later, an empty drum raising session, for drums to be used, to mark the Skiway - the landing strip for the plane.



It wouldn't be too long into the day, that the frequenting weather would change rapidly in both visibility and temperature. Richard unloading the drums approx. every 50 yards along the Skiway, which then will be carefully positioned by a team behind us using a theodolite, so that the plane has a nice straight landing strip with no "dogleg" bends or kinks in it.



Me, digging the drums in a little, as so they freeze into the ice and don't blow away.



Richard and Pete putting the drums in, on the way to the Skiway.



There are many useful skills and abilities, that can be acquired whilst living down South amongst a small team, whom have been carefully selected, for their skills in their chosen profession. None more so than the talents of Matt, who took 3 keen apprentices into the garage for some Mig welding practice.

Me, enjoying the personal firework display i gave myself, and my fellow apprentices.



My first job, welding a nail to a pole, which will be used to mount the recently dug out power cable on.



The 3 Grease "welding" Monkeys, Richard, Dean and me. Although, 2 of them look like they are as happy as a bulldog chewing a wasp.



Due to the Halley 6 build over the next 3 years, much of the science work here will be packed up and sent back to BAS Cambridge. Part of which is the Microbarograph, a pressure sensor 8km away from base, on the Creek 2 drum line. These sensors aid in weather predictions by sensing new weather fronts coming in.

The solar powered weather sensor, which was surprisingly only buried by half a metre or so, is powered by a solar panel which charges the batteries which in turn takes a small amount of power to activate the sensor.



Dave, the met Babe checking his instrument, before packing it away for transport back to Halley, not before a brew, in the crater from the dig.





Probably the last opportunity to visit the cave, made a few years ago from past winterers, before its dug in.





Optimum flying conditions allowed Thomas, the UAV engineer, to perform some of his UAV (Unmanned Aerial Vehicle) flights, which is a first for UAV's in Antarctica, but an ideal place as there is hardly any unnatural influences for the potential data. Data, which is recorded on board, such as wind speed, temperature and moisture, accumulated over different altitudes and land and sea surfaces, all aids in climate change forecasting. The plane travels at approx 40 knots and is launched via a bungee, which is buried by a deadman - plank of wood, the UAV travels at an altitude averaging approx 150 - 300 metres and a distance of 1km away from Thomas.





On a normal Sunday morning with no plans for the day, i was surprised of the offer and the opportunity for another trip to the Penguins, to which i quickly scrambled my gear in readiness for the visit to the zoo.



This time, the Emperors had clearly enjoyed the luxury of feeding, from the state of the defecated ice we were walking on. They also seem to take comfort in being reunited with their partner and sharing the hardship of looking after their very demanding, well nursed chick.





A small creche of baby Emperor chicks, learning at a young age, that huddling together keeps you warm.







In just a few weeks the chicks have grown considerably, so much so they struggle to fit inside the sheltered, warm pouch of their parent. Forcing themselves in, any which way they can. Although these are the more fortunate ones, some parents almost die of starvation whilst looking after their demanding chick, having not fed for nearly 4 months themselves. If their partner hasn't come back in time from the ardeous trek from the sea, to take the other parents place of looking after the chick, the remaining adult faces the hertbreakig prospect of abandoming their offspring, inorder to make the same trek again to feed.







In amongst life, on the Antarctic ice shelf, there is also the inevitable death. Which co-exists along the circle of life of young and old together. The mound in the foreground of the photo is an unfortunate victim, of living in one of the harshes, coldest and windiest places on Earth.







Our mid winter base photo, which will be hanging up on the historic wall of fame within Halley 5, 6 and however many more Halley's there on in. In particular, in rememerance of the Halley 5 melt tank which will no longer be a part of the new Halley 6 building, only recognisable by the mound of snow and ice build up, which has served us all our entire water supply - Homage.



Talking of "homage", seeing as everybody else in their department has photos of themselves of their winter season - Simpson gang, Tech guys. We thought it only fair, to take a stand and take photos of ourselves and leave it here, whether anybody wants to look at it or not.



With the possibility of this being the last Saturday (27th) night, before any visitors and ofcourse Halloween, i decided my last meal for my 18 base members, id bring out the last remaining "Fresh" potatoes, which had lasted well since leaving the Falklands in Dec 06.



Sundried tomatoe & basil rolls
Grilled Cod in a light champagne veloute with a roasted red pepper coulis
Charred Barbary duck with a mango & cranberry sauce
Grilled asparagus with lemon hollandaise
Braised beef fillet steak (or Quorn) with Port mushrooms & caramelised onions
Last of the fresh potatoes, roasted
Lemon posset with pistachio brittle





Harry Potter with a very exagerated wand.



Me kiting, with the Simpson in the background.



Is that "air" between the floor and my feet?



The end of the month was beconning, along with the expected new arrivals, (whenever that maybe), which spurred me on even more to empty my food container, in readiness for the new food to be delivered for the forthcoming year. No mean feat, if you remember how full it was in the Summer last year, and sifting through the stock this time round found some quality gems, still perfectly ok but nethertheless dated "use by" 1999 - cineration for them then.


Craning the food onto the platform.

Skies, Stars & Storms

The start of September bought the last shimmers of light during the night. It would be the finale of the Aurora Australis, and very soon the last sightings of Antarctica's night star constellations, as the daylight starts rapidly taking grasp over the darkness of night. As the nights are quickly drawing to an end, i find myself reminiscing about the luminous starry skies that glistened above us, during our siege of 24 hr darkness. Stars, satellites, planets, galaxies and auroras, all phenomenons visible, yet so far away.

Stars are made up from balls of gases, made incandescent by energy from nuclear reactions deep in their interiors. They come in many sizes and brightnesses, from faint dwarfs to super giants, ranging in temperatures of more than 20,000 degs C in blue-white stars to 3000 degs C in cool red stars. All stars are on an evolutionary pathway, growing and expanding, starting off as clouds of gas and dust, forming into dwarf stars, before entering a main sequence of stars (which our sun is one of them), and then many years later, joining the giants and super giants. Which after that, once they have swollen to their maximum size, outer layers drift off into space, dispersing the surrounding gasses, leaving the remains of the central star called white dwarfs. These white dwarfs have an immense density (a teaspoonful of white dwarf remains would have a mass of thousands of kilograms), ending their particular cycle, slowly cooling off until they fade into oblivion.

Stars appear in different brightnesses, some give out more light than others, and they all lie at vastly differing distances. So a small star that is quite close to us can appear brighter than a phenomenally powerful star that is further away. A stars brightness is measured by magnitude, from 1st magnitude - brightest stars, to 6th magnitude - the faintest. A stars distance is measured in light years - the distance a beam of light travels in one year. Light moves at the fastest known speed in the Universe, 299,792.5 km per second, and on average stars are several light years apart.

Aurora Australis taken on 2nd Sept at 02.10, with Jupiter glowing in the middle right of the photo. Notice how far Jupiter has moved in just 5 days, compared to the below photo.



The Scorpius constellation lies in a rich area of the Milky Way, and is surrounded by star clusters. M7, is a huge cluster of 80 plus stars with a 3rd magnitude rating, and lies 800 light years away.

The Southern Cross (Crux), lies in a dense part of the Milky Way, with a dark nebula known as the Coalsack silhouetted against the starry background, and is estimated to be about 400 light years away.

The Centaurus constellation contains the closest star to the Sun, alpha, which is actually three stars linked by gravity, is 4.3 light years away and is the third brightest star in the sky. Centaurus, is one of the strongest radio sources in the sky, and is associated with the galaxy NGC 5128.

An unfortunate death occurred on the 14th Sept, during a period of relentless strong winds and blowing snow - The death of the Blimp, which was rattled inside the weather haven like a dog with a new toy. On reflection of our loss, here on base a mourning period was shared, fond memories were gathered, and a "Wake" at the expense of the Blimp, was attended.

Inside the Blimp, being pitched by one of Jules's crutches decorated with fairy lights.



However, the mourning was short lived. As the following day celebrations were underway for another 30th B'day here at Halley, and a subsequent two more B'days shortly after. Starting off with a London Tube Station Party on Sat 15th for the, "Not so young anymore", Dr. R. Corbett.



Can u guess the tube stations? i.e. Mark on the far left, is Elephant & Castle station, Dean on the far right with a crook and a wig between his legs is............................?? Shepherds Bush station, and so on.



Another appearance, of an Antarctic ice bar, on the 18th Sept. made for Richards real 30th B'day celebrations, with a dodgy liquor bought from who knows where, along with handmade ice glasses that drew blood on your lips from the minus 35 Degs C temperatures, followed by real Uruguayan cigars.



The following weekend saw Neil the Caslab Chemist, celebrating his elusive possible 39th, 40th, or even 45th B'day, with a Toga & Gods party. Although, most looked as if they'd fallen out of bed and waddled into the lounge with their bed sheets stuck to them.



Richards B'day cake for Neil, with great poignancy towards remembering Neils leg kissing a fur seal - chomp, chomp.



The "Gods" playing pool.



Neil as Atlas.



The last of the Sept B'day celebrations, saw Jules, the electronic engineer, reaching his 29th B'day here in Antarctica, on 28th Sept. Which luckily for him, Halley, was being visited by some very special (or different) visitors, to join in the frolickings.



The new visitors making themselves at home, and preparing for the night ahead.





In amongst all the hype of Birthdays and longer daylight hours, a small window of reprieve from constant blows and poor weather, warranted a refueling session of the Laws.

Me and Andy, the Fixed Plant Technician, refueling one of two, of the 20,000 litre capacity Dunlop flubbers, which fuels the laws building. The far side of the flubbers wall receiving all the pressure from the crushing ice.



A rare day for September, but much appreciated. The winds died, the clouds diminished and a solar Halo with two Sundogs either side shone throughout the day. A phenomenon which only occurs in the Polar regions. But, it was too much to ask for more than a day of "Dingle" weather.



A few days later, a drum raising trip to Windy Caboose, to save the 205 litre empty black drums from being completely buried in the persistent blows, which aid us on our way to and from the Penguin colony there.

Me supervising Jim and Matt digging out a drum.



Familiarity, 30knot plus winds, again. The rope in the photo is tied to a six foot pole, at which the manhole style cover to the melt tank is fastened. Barely one foot visible. A digging session in itself, before we can even fill the melt tank. Although this month the wind officially peaked to 62.8 knots, registering a violent storm, bearing in mind a hurricane starts at 64 knots.
