USGS Topo Map of Patriot Hills Region (Oriented North)



Here is a US Geological Survey topographic map of the region immediately surrounding Patriot Hills, which I hope to explore in my rare days off. The base camp is in the center of the map, about a third of the way down. I hope to help install a VHF repeater up in the hills to increase the coverage area for VHF handheld radios used to communicate with staff and expeditions.

As it will be difficult to send images once I reach Patriot Hills, I will refer to this and other online maps and photos as a reference in future blogs. I recommend that those of you following along download the detailed and far more useful (not to mention beautiful) version of this map found on the Web at http://usarc.usgs.gov/drgs/c80077s1.jpg

US Navy Aerial Photo of Patriot Hills: Facing Northwest



Patriot Hills is the small set of hills in on the right. The katabatic winds come whipping down from the 9,000' elevation at the Pole (left to right in the photo) and blow the snow off the ice on the downwind side, creating one of two "blue ice" runways in Antarctica.
This one is 7,500 feet long by about 160 feet wide, enabling it to handle craft as large as the chartered Ilyushin 76 jet that arrives weekly (weather permitting). The jets are flown on their ten-hour round-trip journey by Russian crews with whom I will be speaking enroute from Chile via HF (Shortwave) and Iridium satphone.
What makes it complicated is that the katabatic winds blow perpendicular to the runway and Ilyushins, with their big tails, do not cotton to crosswinds above 18 knots, so the key decision is the "go or no-go" one that must be made before the plane departs Chile. Patriot Hills has a full-time meteorologist on staff who will sit in the same hut as I. He will rely on various sources of weather information, including automated weather stations set up by Stanford University a hundred miles or so upwind towards the Pole.

Gigi Says: "Good Thing They Didn't Ask Me If You Can Cook!"

The folks in Antarctica had a pretty definite idea of what they were looking for. Aside from cooking, Gigi said that this was a job I had preparing for my entire life. Here is the hiring criteria they had prepared:

· Native English language speaker. If not native, then a demonstrated high oral proficiency in
English with no heavy accent that would impede clear voice communications over radio

· Previous experience with aircraft operations involving fixed wing aircraft and / or helicopters using long haul HF SSB and short haul VHF AM or FM voice circuits.

· Demonstrated ability operating modern HF Single Side Band & VHF radio receivers and transmitters.

· Demonstrated ability with standard ITU radio procedures, codes and log keeping

· Demonstrated ability with standard ITU Distress, Urgency & Safety communications procedures

· Demonstrated ability to operate satellite equipment for voice and data calls. Understanding of satellite orbits, especially differences between geostationary and polar orbits and associated advantages / limitations.

· Ability to touch type (or otherwise type reasonably fast)

· Commercial Radio Operator License, Unrestricted (Full) Amateur License.

· First Aid certificate

· Understanding of HF (ionospheric) and VHF (line of sight) propagation & limitations

· Understanding of HF & VHF antenna theory. Able to diagnose and rectify simple antenna faults using basic test equipment and tools

· Familiar with and able to use basic radio test equipment such as Voltage Standing Wave Meter, Power Meter, Volt Meter etc.

· Demonstrated ability to use a soldering iron

· Able to understand block and circuit diagrams and diagnose major equipment & component faults (such as blown transistors, short circuit diodes, open fuses, short circuit capacitors, burned out resistors etc.) using basic test equipment

· Understanding of solar panel technology & its limitations (such as max. current per unit of solar radiation / insolation angle etc.), DC Voltage regulators DC – AC converters

· Understanding of different types of batteries (Lead Acid wet & gel, Nicads, Nickel Hydrides, Lithium Ion, Lithium Polymer etc. and the different charging regimes.

· Understanding of Specific Gravity & able to use hygrometer to diagnose when a battery has past its “useful service life” (i.e. not holding charge, not able to deliver sufficient power at a specified current etc.)

· Able to diagnose and rectify simple faults in power supplies, voltage converters, chargers & batteries.

· Understanding of (and able to tell the difference between) natural and man-made interference, how it is caused and general methods used to reduce or eliminate it

· Computer skills: Intermediate computing knowledge. ALE uses PCs, mostly running Windows OS, some using LINUX.

· Computer skills: Proficiency using Microsoft Office suite (Word, Excel etc.) Able to assist others in ‘helpdesk’ style tasks.

· Computer skills: Familiarity with main web browsers (Internet Explorer, Mozilla, Netscape, etc.)

· Computer skills: Familiarly with main email clients. POP3 and similar

· Mechanical skills such as able to repair or make simple metal or wooden articles using basic mechanical tools (drill, hacksaw, file, taps & dies etc.)

· Understanding of and / or previous experience using HF data modes such as Pactor, or Amtor.

· Computer applications knowledge in common packages such as Microsoft Word & Excel (i.e. “help desk” type skills – assisting staff & clients with problems associated with using a particular applications package, rather than dealing with a software bug or loading problem).

· Computer networking skills, knowledge of Ethernet, TCP/IP, Ping command & Wireless LAN,

· Able to set up peripherals such as printers, scanners, digital cameras etc.

· Understanding of data protection and confidentially issues

· Rigger experience, e.g. able to use a gin pole, swage machine, turnbuckles, bulldog grips, D shackles etc. Understanding of mechanical stress, strain, guying techniques, pulleys etc.

· Language abilities in Spanish or Russian

· Proficiency in Morse Code (any speed)

· Communications Tower Rescue training or experience

· Mountain Rescue or similar “Search & Rescue” type training or experience (such as Fire Brigade, Police, Armed Forces, National Guard, State Emergency Services)

· Understanding of meteorological instruments & observations, experience with AWS

· Cooking Skills

· Advanced First Aid / Paramedic skills

The E-Mail From Australia That Hooked Me


To: Antarctica List
From: Alan Cheshire
Subj: Job Opportunity - Antarctic Radio Operator
Date: 8/14/2006 10:00:25 PM Eastern Standard Time

I am looking for someone for a temporary position as a radio / communications operator at Patriot Hills, Antarctica this coming season. The job involves maintaining voice communications with Twin Otter aircraft and mountaineering parties on HF, VHF and Iridium satellite. This would suit an experienced HF amateur radio operator and is a paid position with airfares to/from Punta Arenas provided. Patriot Hills is located at 80 degrees South, at the southern end of the Ellsworth Mountains and is serviced by a weekly 5 hour flight on an Ilyushin 76 cargo jet from Punta Arenas, Chile. Accommodation, food etc.at Patriot Hills is provided free of charge. Dates are approximately mid October 2006 to end of January 2007, but a shorter period may be negotiated for suitable candidates. The position requires very good English language skills and a reasonable level of fitness. Initial expressions of interest to me via my email address.

My Journey

During the third week of October, I am heading down to the Antarctic interior for three months where I'll work as a Communications Officer at a remote field camp called Patriot Hills, about 600 or so miles from the Pole. I have dreamed of working in Antarctica since I was fourteen years old, and when the possibility of fulfilling this dream came 38 years later in the form of an email from Australia about two weeks ago, I was powerless to resist. Gigi and the entire family have been enthusiastically supportive. There is no Internet access at the base but there is limited access to email, so I have established this blog to keep you all up to date. Please feel free to post comments. Adam
