When Argentina celebrates the  “Dia de la Patria” our Ham friends of Ushuaia –Tierra del FuegoWAP ARG-23,  did join the event and add the 35th Birthday to the Radio Club Ushuaia LU8XW to it.

This year due to a pandemic Covid 19, Hams from Ushuaia did celebrate the happening on VHF (they  met at 146,520) and with Guillermo LU8XQL,  through Echolink at 145.6 . They toasted to this date so loved by all.  Long Live the Homeland !!!!

WAP joins the fest and wish our friends down to the land of  “the end of the worrld” a great happy birthday of their “Radio Club” !

Researchers go cuckoo: Antarctic penguins release an extreme amount of laughing gas

In a new study, researchers from the University of Copenhagen have demonstrated that penguins in Antarctica emit copious amounts of nitrous oxide via their feces. So much so, that the researchers went ”cuckoo” from being surrounded by penguin poop.
More than 1600 kilometers east of the Drake Passage between South America and Antarctica lies the Atlantic island of South Georgia.
Here, king penguins live in huge colonies. Their days are spent chomping on krill, squid and fish, feeding their chicks and producing ‘guano’, which means poo in penguin. Nothing mind-boggling about that, you might say.

However, there is something very special about the comings and goings of king penguins. Tremendous amounts of nitrous oxide, better known as laughing gas, are released via their guano, according to a 2019 study completed by researchers from the University of Copenhagen and their colleagues.

“Penguin guano produces significantly high levels of nitrous oxide around their colonies. The maximum emissions are about 100 times higher than in a recently fertilised Danish field. It is truly intense — not least because nitrous oxide is 300 times more polluting than CO2,” explains Professor Bo Elberling, of the University of Copenhagen’s Department of Geosciences and Natural Resource Management.

Besides being a strain on the climate, nitrous oxide has an effect very similar to the sedative laughing gas used in the dentist’s office ….

Is Antarctica the Safest Place to Visit in 2020 and beyond?

If your dream has been to follow in the footsteps of the great Antarctic explorers Amundsen, Scott and Shackleton, this could be the ideal time to do so. Antarctica is vast – roughly the size of China and India combined – and is the coldest, windiest, driest and highest-altitude continent on Earth and the only continent with no native human population. Nobody owns, or can claim sovereignty in Antarctica and it is governed by an international treaty signed by 54 nations. The Antarctic Treaty sets Antarctica aside as a scientific preserve, establishes freedom of scientific research and bans military activity on the continent. Emperor Penguins and spectacular scenery aside, knowing that Antarctica is the only continent with no confirmed cases of COVID-19 makes it even more appealing. It is an excellent place to holiday, post COVID-19, as it is the ultimate in inert environments.

Plus, the vast open landscapes are the exact opposite of all we have been enduring while in lockdown and offer holidays focused on mindfulness and escapism – the opposite of a hectic city life

Almirante Brown, Argentine Station at Paradise Bay

Brown Station (WAP ARG-Ø2) is an Argentine Antarctic Base and scientific research station named after Admiral William Brown, the father of the Argentine Navy.

It is located on Sanavirón Peninsula along Paradise Harbor, Danco Coast, in Graham Land, Antarctic Peninsula. As of 2014, Brown is one of 13 research bases in Antarctica operated by Argentina.

From 1951 to 1984 it served as a permanent base; since then it is open during the summer season only. Brown Station dates to 6 April 1951, when Argentina established the Almirante Brown Naval Detachment at Paradise Harbor. In January 1956, the Argentine Navy inaugurated the Refugio Naval Conscripto Ortiz (Conscripto Ortiz Naval Refuge). The detachment worked as a meteorological observatory and as a base for Antarctic campaigns until it was temporarily closed in 1960.

The Argentine Antarctic Institute took over the station in 1964–65, creating one of the most complete biology laboratories on the Antarctic Peninsula. It included a main house of 292 m2 (3,140 sq ft); two folding 30,000 l (6,600 imp gal; 7,900 US gal) fuel tanks; and an additional building exclusive for scientific research, equipped with three labs, photography workshop, emergency radio station, office and library. It was called Almirante Brown Research Station and inaugurated on 17 February 1965. Brown Station’s original facilities were burned down by the station’s doctor on 12 April 1984. Station personnel was rescued by the ship USS Hero and taken to United States’s Palmer Station. Argentina rebuilt the base but it was demoted to summer-only status.

During the summer campaign of 1995–96 the Logistics Department of the Argentine National Antarctic Directorate built two new habitable modules: a laboratory and a house with amenities. In the 1999–2000 campaign the Directorate built a new main house capable of comfortably accommodating 8 people; the new building consists of 4 bedrooms, kitchen and 2 bathrooms. Brown slipped into several years of inactivity during the 2000s decade but since 2007 is occupied during the summer again. Paradise Harbor is a large sea inlet southwest of Andvord Bay protected by an arc formed by the Lemaire, Cramer and Bryde islands. Along the harbor’s deep water coast lies the small Sanavirón Peninsula, a rocky promontory crowned by a mound of almost 70 m (230 ft) high called Punta Proa, where the base facilities are located. In the area there are several beacons to help ship guidance: Punta Proa, in the homonymous place; Punta Vidt in General Ricchieri Cove; Punta Conesa, on the entrance to Puerto Leith; Hanka islet on the homonymous place in Paradise Harbor; Punta Piedras in Oscar Cove; and the lighthouse on Cramer Island.

Brown is located 1,100 km (680 mi) from Ushuaia, the nearest port city. As of 2014 the base spans a total area of 1.4 ha (14,000 m2; 150,000 sq ft). It can house a maximum of 18 people. Research programs were developed for biology (zoology and botany), bacteriology, limnology, biochemistry, animal and human physiology, pathology, ecology, oceanography, meteorology, cosmic rays and ionospheric observations, environmental nuclear radiation, continental and sea ice glaciology, satellite geodesy, geology, geophysics, seismology, ozone monitoring and tide measurement.

Throughout the years of research and observations at Brown, more than 100 scientific papers were published by the Argentine Antarctic Institute. Thanks to its location on the Antarctica continent along the beautiful Paradise Harbor and to its relatively mild weather, Brown Station is a popular excursion destination for tourist expedition ships visiting Antarctica. In addition to visiting gentoo penguins, tourists may climb to a viewpoint 84 m (276 ft) above the station.
Almirante Brown (WAP ARG-Ø2) has been active sporadically from 1979 throug 2004 by LU1ZB & LU1ZE. It is considered a rare one. On 2006 VP8DJK was briefly active from there as well. Last activity was performed on 1 & 2 march 2009 by Mehdi F5PFP signing LU/FT5YJ

The Forgotten American Explorer who Discovered Huge Parts of Antarctica

It’s been 180 years since Charles Wilkes (April 3, 1798 – February 8, 1877) an American naval officer, ship’s captain, and explorer led the United States Exploring Expedition, 1838-1842. He voyaged to the Antarctic continent and his journey has never been more relevant!

The early-1900s exploits of intrepid explorers like Robert Scott and Edward Shackleton captured the public imagination. With the benefit of cameras and deft handling of newspaper media, the Edwardian British explorers, alongside their Norwegian rival Roald Amundsen, established themselves as heroic polar pioneers. In the process, however, the south polar exploits of their American forerunner, Charles Wilkes, have been largely forgotten.

It was the round-the-world expedition by Wilkes, whose scientific collection constituted the first treasures of the infant Smithsonian, that first established the continental dimensions of Antarctica. But in a twist of 19th-century international politics, that claim to Antarctica was denied to the Americans by the pole-hungry British. Fast forward to today, and the United States finds itself in another nationalistic race to capitalize on the frozen southern continent. This time, its sparring partner is China.
Amundsen might have been the first man to reach the South Pole, in 1911, but the discovery of the Antarctic continent occurred several generations earlier. In January 1840, when Wilkes was commander of the United States Exploring Expedition, he charted 1500 miles of the east Antarctic coastline in his flagship U.S.S. Vincennes (picure on the right, shows the  19th-century painting, based on a sketch by Lieutenant Charles Wilkes, USN, depicting USS Vincennes in Disappointment Bay, Antarctica, circa January–February 1840).

Before this American expedition, only small, rocky outcrops of Antarctica had been sighted. Most exploreres believed an open polar sea or, at most, a scattered archipelago lay at the planet’s far south.

Lockdown in Antarctica: Life on an Indian base on the only continent untouched by Covid-19

We remind our  friend Ham radio Bhagwati Prasad Semwal, VU3BPZ (on the pic aside while at Maitri Base) when reading the article below, which gives  our readers an idea on what means  a Scientific campaign in Antarctica. Not only a pleasure of a selfy with penguins, not a vacation in a paradise  but study, scientific projects,  researches and experiments, hard life away from the normal activities at home.

Bhagwati (VU3BPZ) is an Antarctic veteran,with several campaigns in Antarctica as Communication Officer at Maitri and Bharathi Bases and we are happy  for the opportunity to to recall him, who is fine at home now!

Isolation and confinement are the natural state for researchers on the icy continent. Now, the whole world is in the same position.
Antarctica is the coldest, driest and windiest continent on Earth. The extreme conditions of Antarctica have ensured that the environment here is in pristine shape and have also made this the most isolated place on the planet.
I have been here since November 2019, as the medical officer to the 39th Indian Scientific Expedition to Antarctica –says Dr Pradeep Tomar – at India’s Bharati Station in Antarctica. The continent is home to around 70 active research bases belonging to various countries. These bases house more than 4,000 people during the summer and around 1,000 people in winter. They spend an entire year in isolation, conducting research projects on the icy continent.

India has maintained a strong presence in Antarctica since 1981. Every year, summer and winter teams are sent to two Indian research bases, Maitri (WAP IND-Ø3 pic to the left),  and Bharati (WAP IND-Ø4 pic to the right ), to carry out diverse scientific studies. This year, the winter team has 23 members deployed at the Bharati station. It is my responsibility to conduct regular health check-ups to ensure the physical and mental wellbeing of my team mates.

The situation on the continent feels uncommon this year, with the worrisome outbreak of coronavirus in India. Back in November when the expedition had just begun, the world seemed to be in its usual state. A month into the expedition, we started hearing the news about the spread of coronavirus. Now, we don’t really know much about the situation back home. Members are worried about their near and dear ones as India is moving through Lockdown 3.0.

We had never imagined that the whole world would be in a situation similar to ours.

Coronavirus: How amateur radio is connecting people during lockdown

Amateur radio use in the UK has seen a “significant” rise during the coronavirus lockdown as people seek new ways of staying connected. The national body that represents users – the Radio Society of Great Britain (RSGB) – has said many people who formerly enjoyed the hobby are also returning to it.

Mark Rider‘s social life before the coronavirus lockdown consisted of the occasional trip to the pub, rehearsing with musician friends and visiting his wife in her care home.

“But when I knew that wasn’t going to happen any time soon I decided to dust off my amateur radio equipment to seek out some other social interaction,” he says.

Mr Rider, a retired engineer from North Warwickshire, said “ragchewing” – or chatting to people on the airwaves – “has become one of the highlights of my day”.

“Because I live on my own, and because of lockdown, I knew I couldn’t do what I used to do, which wasn’t going to be very good for me or my mental health.”

Demay Refuge at Paradise Cove – WAP POL-NEW

Located on ASPA 128, Demay refuge (wood hut) 62°13’ South,    58°26’30” West,   is situated on a flat marine gravel terrace in Paradise Cove between Demay Point and Uchatka Point. The refuge can be reached both by Zodiac and by foot.

How does the paradise look like? This question can be answered by the station crew, in particular by those involved in the environmental monitoring. A little Paradise Cove is located about 10 km from Arctowski Station (WAP POL-Ø1), within the Antarctic Specially Protected Area ASPA-128. In there, there is a little cottage above whose door there is a sign ‘RAJ’ “Polish for Paradise”. The refuge provides shelter during the regular trek along the SW shores of Admiralty Bay when we count pinniped mammals. Over the years lots of people stayed in the cottage: glaciologists working at the Windy and Tower Glaciers, geologists studying rock formations at Red Hill, Baszta and Bastion Hills, so called  “debris guys” measuring outflow from the Baranowski Glacier and collecting bedload…

Their memories are preserved in the cottage guest book. The refuge contains two bunk beds, gas cooker, stove and even a shower. There is a VHF radio available with antenna on the rocks above the refuge. It is perfect for hiding from the cold, wind, blizzard and heavy rain. Those who stayed in the Paradise overnight can confirm that few earthy pleasures compare to a dawn on the veranda with a warm cup of tea in hands and a view over a calm horizon decorated with icebergs, waves breaking against the rocks of Demay Head, sleepy elephant seals and playful furseals.

So far, no one has been operate Ham Radio from there and we strongly expect some of the polish friends to be active on the HF bands to give all of the Antarctic chasers, a great chance to work a brand new Antarctic Hut!

Historic Old Huts at Macquarie

We have already came across the Huts at the Sub-Antarctic  Macquarie Island (WAP AUS-Ø8), on last april 2019, see: http://www.waponline.it/a-quick-tour-among-the-huts-at-macquarie-island/.

Today we’ll have a brief tour through the historical Huts on the same island:

Historic Old Sandy Bay Hut Everyone on the island, and all the tourists who visit, are familiar with the little old field hut at Sandy Bay. It is solid as a rock and banded with rusty iron, tussocks grow on top and roosting skuas keep watch over the surrounding king penguin colony. It is a picturesque sight.

The door bolt is rusted shut, but expeditioners can peer in the grubby window at a dark, decrepit interior festooned with penguin-moult feathers caught up in spider webs – very atmospheric. Feathers from moulting penguins can be found everywhere, as we know from doing our weekly communal clean-up duties. It is amazing how they can sneak through the tiniest crevices in buildings.

Historic Old Lusitana Bay Hut

The little old Hut at Lusitania Bay (54° 42′  South, 154°50′ East)  just north of the king penguin colony. The huts are old Walrus aircraft engine packing crates, put in place in 1949. They served as field huts for many years and still could have, no doubt, except that the king penguin colonies at Sandy Bay and Lusitania Bay overtook them both and they were abandoned in favour of the new huts at Brothers Point and Waterfall Bay. (pic aside show Lusitania Bay’s penguin colony)

Other Huts at Macquarie Island

Huts and try works were located at the Isthmus, Sandy Bay, Lusitania Bay, Caroline Cove and Hurd Point. Russian explorer Thaddeus Bellingshausen visited Macquarie Island in 1820 and reported that a total of 40 men were working on the island. He also left an interesting description of the sealers hut at Sandy Bay which was:

20 feet long by 10 feet broad, inside it was lined with skins of seals, the outside was covered with a kind of grass which grows on the island. At one end was a small hearth, and a lamp was always kept alight. … Beside the hearth was a bedstead. Provisions were stored at the other end of the hut. Inside it was so black and dark from the smoke that the smouldering light from the lamp and from the holes in the wall over which bladders were stretched, scarcely lit the interior of the hut, and until we got accustomed to the light the sealers had to lead us by the hand.

Let’s have a look to the others removed Huts:

With the long awaited recognition that Macquarie Island was cat free this last season, there was no longer any justification for the presence of the three plateau Field Huts that  had been established some years ago to provide accommodation for the Tasmanian Parks and Wildlife staff involved in the cat eradication project, part of the Vertebrate Pest Management Program:

They were:

Mt Eitel Hut (54° 36.6′ South, 158° 50.9′ East),

Lake Tiobunga Hut (54° 41.7′ South, 158° 49.2′ East)

Windy Ridge Hut (54° 44.0′ South,  158° 49.8′ East).

Another Hut was established at Davis Point in 1993 for the purpose of conducting the marine debris survey.

Davis Point Hut (54° 39.9′ South, 158° 49.5′ East) There is a small hut at Davis Point (pic aside) used for special fieldwork and as a refuge, which catches rain water off the roof. Davis Point hut is a cross country transit to Green Gorge Hut

The Davis Point Hut is one of seven shelters dropped across the island for hunters and their dogs tracking rabbits. They were a vital part of the Macquarie Island eradication of pests.

As this work will now be centered on Bauer Bay, there was no longer any need for this hut to remain on the island. Mt Eitel apple hut packed up. Rat-proof cage pallet in foreground. March 2003

When the ship arrived at the end of March, the helicopters were deployed to lift both the Davis Point Hut and the three apple huts from the plateau, by cable sling and transport them back to the main station area. Each hut was accompanied by two pre-packed cage pallets, gas bottles and a black rat-proof cage pallet with perishable items such as food. It took about three to four hours of work to totally remove each of the apple huts and their contents.

All four huts were then transported by helicopter from the Isthmus to the ship ready for return to Australia.

IAØ/DK5SQX Concordia Station WAP MNB-Ø3

While talking of his Antarctic experience, Marco De Pas (DK5SQX-IK5SQX) is happy for such a great professional and human experience lived in the Icy Continent. -Our LIDAR a kind of optical radar that does “Cloud ranging” works perfectly and that’s great- Marco said!

The only disappointment is about the Ham Radio: too many restrictions, too many constraints on the use of  HF Base equipments. This kind of unnecessary bureaucracy, poorly contrasts with the skill of a licensed Ham radio operator, but rules are rules, so that the free time to dedicate to the HF was strictly reduced, practically nothing!

Nevertheless Marco could test propagation from that remote Concordia Station at 75°06’06” South,  123°23’43” East and even if conditions were not favorable,  he logged few QSOs  signing IAØ/DK5SQX and now, QSLs have been sent to the lucky  and patients OM who worked him on last January 2019.
Same situation at Dumond D’Urville (WAP FRA-Ø1). Down there, Marco could meet the Responsible of the Radio room,  who did show him the HF setup… too bad the VFO was unstable  with shifting frequency, so practically unusable … what a kind of conspiracy!
It could be that next season,  Marco will be call to return in Antarctica again. Next time -he said- I will bring my own equipment and a small amplifier so I will be independent and I can operate without interfere with the Base activity where the radio room is mainly used for air traffic and contacts with field camps.
