Highline Operation at McInnes Island c. 2004

Aerial highline - photo Glenn Borgens

The highline (aka aerial line, or aerial) was literally the lifeline of the lighthouse in the days before helicopters. It was used and still is used to raise and lower heavy supplies to and from the lighthouse. They were not installed at all lighthouse locations – only the ones with no other access to the ocean within a reasonable distance of the station. For example Cape Scott  has a highline but also has beach access but no one would want to move supplies that distance by hand or by road so a highline was built. Some other stations with highlines are Carmanah, Pachena, Cape Beale, Quatsino, Green, Pine, and Bonilla.   Continue reading Highline Operation at McInnes Island c. 2004

The Diaphone Fog Signal

The Diaphone Fog Signal by Jeff Laser

reprinted with permission from Terry Pepper and his website

Diaphones were a once familiar sound heard throughout the Great Lakes from the early 1920s until the late 1960s / early 1970s when most lighthouses were automated. 120 such installations existed on both U.S. and Canadian waterways in the 1950s. The two most commonly heard Diaphones were the “Standard” Diaphone, which gave a full steady upper tone that terminated in a heavy “grunt” tone, and the classic two-tone Diaphone that produced an upper tone followed by a full steady low tone of equal or greater duration than the upper tone.

 

Robert Hope-Jones

In 1895, Robert Hope-Jones, an English pipe organ designer and builder, developed a special tone generator for his famous WURLITZER organ; the WURLITZER was a popular musical instrument in the days of silent movies and live stage performances. The new tone generator consisted of a casing that contained a slotted cylinder with a similarly slotted piston. Air was channeled through the casing in such a way that it caused the piston to reciprocate within the cylinder. The major portion of the air was discharged through the slots in both the piston and cylinder as the piston stroked back and forth in the cylinder. As the air passed through slots in the piston, it was “chopped” which caused a vibration that was amplified though a long cone shaped trumpet. Hope-Jones labeled this new tone “diaphonic” (meaning two or more tones”). The new tone had a full, powerful harmonic structure that could be heard over some of the other tones on the pipe organ. He called his new tone generator a Diaphone. Continue reading The Diaphone Fog Signal

‘F’ Type Diaphone Foghorn c. 1969

The diaphone is a unique organ pipe. The theory was based on a design for the Wurlitzer pipe organ invented by Robert Hope-Jones dating from 1895.

A special tone generator in the organ involved a piston vibrating inside a cylinder, which had slots through which air was discharged. The air passing through the slots caused a vibration which when amplified through a long cone (like a megaphone) created a powerful harmonic sound.

Robert Hope-Jones also applied this principle successfully to foghorns, and this then became the most common type of navigational aid in the world. Continue reading ‘F’ Type Diaphone Foghorn c. 1969

The Storm of October 1984

The article I posted earlier about the storm at Cape Scott brought to mind a story I had written for the old website. This story (below) brought to the attention of the government one of the important attributes of BC lighthouse keepers – they are on-site!

Helicopter pad at McInnes

On Thursday October 12, 1984 Roger Mogg (my assistant) and I were up at the helicopter pad at McInnes Island  lighthouse enjoying the clear Fall weather after lunch. We had been shooting clay pigeons with our shotguns and a newly acquired launcher. The wind was light, with very few clouds in the sky, so it made a perfect day for target practice in between weather reports. 

Just then Karen called up that Stan at Egg Island  had just notified the Coast Guard radio station in Bull Harbour  that he had unexpected high winds and seas. Roger and I looked at each other and joked that Stan must have been into his home-made wine again! Looking down towards Calvert Island  (between us and Egg Island) from our location on the helo (helicopter) pad we could see only clear sky with a trace of cirrus cloud. Calvert was over forty miles (64 kms) away and we could just see the top of it on the horizon. Egg Island was further south still.  Continue reading The Storm of October 1984

Recent Storm on Cape Scott 2012

Every winter the West coast of Canada is pounded by storms with Hurricane Force winds (scale 12 on the Beaufort Scale).

Below you can read what the lightkeeper at Cape Scott lighthouse posted for this April 02, 2012 storm. The keeper, Harvey Humchitt, Jr. posted this information on his Facebook page.

02:05 PST MONDAY APRIL 2, 2012 HURRICANE FORCE WIND WARNING FOR CAPE SCOTT.
Wind southwest 10 to 20 knots (18 to 37km/hr) increasing to southeast 20 to 30 knots (37 to 55km/hr) this afternoon and to 30 to gales 40 knots (55 to 74km/hr) early this evening. Wind increasing to southeast storm force 50 to 60 knots (92 to 111km/hr) near midnight except HURRICANE FORCE 65 knots (120km/hr) near the headlands Monday morning. Wind diminishing to southwest 25 to gales 35 (46 to 64km/hr) near noon Monday.

04:43 PST MONDAY APRIL 2, 2012 Hurricane is here full force hittin us hard at 80 knots 150km/hr, and a ton of rain

07:34 PST MONDAY APRIL 2, 2012 We were hit by almost 200km/hr winds that took out two storm doors, the crown on a spare house, the siding on a spare house and flooded our engine room. Winds are still gusting to 180km/hr, and horizontal rain.

11:38 PST Final Hurricane status report, winds hit 230 km/hr, lots of heavy rain that dumped 40mm of rain and the seas hit near 30ft. Damage done, two screen doors lost, siding on one house gone, crown on roof…gone, flashing for roofing…..gone, 3 trees fell, bassement in spare house flooded, engine room flooded and a stick punctured a hole in our sat dish for the tv but still works. In all….a typical British Columbia North Coast Hurricane. This is probably the last Hurricane force wind we will see now until the fall.

I do not think I have ever seen a storm like this when I was on the lighthouses – at least one  quite as strong in intensity. Climate change? 

Below are some photos Harvey made after the storm had gone through. Note the stormy seas and ragged clouds. Remember, these were made after the storm passed over. During the storm you cannot even get outside the house sometimes.  (All photos credited to Harvey Humchitt, Jr.

In Memorium – Prospect Point Lighthouse – Automated!

Prospect Point Lighthouse

Latitude 49 18 50.4N, Longitude 123 08 29.1W       List of Lights #392 

Established: October 01, 1888       Automated: January 1926 

Three nautical miles east of Point Atkinson, situated at the base of a cliff, stands the lonely and short-lived lighthouse called Prospect Point.

The light was first manned in October 1888 and was overshadowed by the importance of the Signal Station on the cliff above. This signal station operated in conjunction with Brockton Point  to signal when ships were coming into or out of Vancouver Harbour. 

In January 1926 the poor lightkeeper was informed by the Department of Marine and Fisheries that the lighthouse would be electrified and would then be operated by the Prospect Point Signal Station. He was out of a job after years keeping both systems working.

As mentioned above, the Prospect Point and Brockton Point signal stations monitored ship traffic in and out of Vancouver harbour. 

Just across the harbour from Prospect Point, at the mouth of the Capilano river, was the tiny little-known Capilano lighthouse (aka First Narrows). (see Capilano webpage here.

Below is a photo taken from the mouth of the Capilano River showing Prospect Point today and the the probable view from the Capilano lighthouse. Beside it is a Google Earth map showing the exact location of the three lighthouses.

Grocery Mishap at Kains Island (Quatsino) c.1975

CCGS Sir James Douglas

 The landing under the hook (aka highline) at Kains Island was a large basin at the back side. It looked like a very large boulder had been washed out from the hole. It was a bit tricky if the swell was running to bring the station inflatable in safely but we never had a accident in my three years on station.

After a SE winter storm the hole would fill up with kelp stems broken off the surrounding reefs by the large swells. The swells then pounded this kelp into a tan-coloured foam which drifted all over the ocean and blew up into the trees and hung there like lichen. It was quite light but sticky to the touch.

One winter day we were expecting the supply ship with groceries, mail, etc. One of the Coast Guard buoy tenders arrived rocking and rolling in the swells in Quatsino Sound. Over the side went the workboat and then began the process of off-loading the supplies into her. We could see the orange-suited crew members on deck and in the boat but could not recognize anyone.

As we watched the workboat pull away from the shelter of the ship we were called on the radio by an unknown voice that the boat was on its way in. We acknowledged and commented that this appeared to be a new mate. Always fun to see how much experience they had unloading under a highline. 

The boat rolled across the half kilometer distance between us and the ship, sometimes disappearing completely in the swells. The mate brought the boat closer to shore and lined up with the small bay, all the while ploughing a path through the foam which was pushed aside by the bow. As the boat neared the gap the mate rode a swell in under the hook and all but completely disappeared! 

We could see well from the winch shed and the highline deck but only heads were showing in the workboat – the rest had completely disappeared! During the night the storms had lashed the kelp to pulp and filled the gap with sea foam to almost a metre deep! The workboat rode in on the swell and right under the foam.

 Pushing the foam aside, the crew grabbed the lowered hook, slipped on a set of slings and signalled Haul Away. As the bonnet sling left the well of the workboat it also left a nice clean spot in the boat. On landing on the highline deck above, it was discovered that everything was covered with the sea foam, but, all was OK on the inside of the cartons of groceries and bags of mail although a bit sticky on the outside. The foam, although appearing quite dense, was actually quite dry and no harm was done. 

The mate was a little more cautious when he came in with the second load.

 More information about the sea foam. Below is the content of an email I received in March 17, 2008.

HERE’S SOMETHING WE’LL NEVER SEE………WHIPPED OCEAN……..AMAZING!

Suddenly the shoreline north of Sydney was transformed into the Cappuccino Coast . Foam swallowed an entire beach and half the nearby buildings, including the local lifeguards’ centre, in a freak display of nature at Yamba in New South Wales .

One minute a group of teenage surfers were waiting to catch a wave, the next they were swallowed up in a giant bubble bath. The foam was so light that they could puff it out of their hands and watch it float away.

Boy in the bubble bath: Tom Woods, 12, emerges from the clouds of foam after deciding that surfing was not an option

It stretched for 30 miles out into the Pacific in a phenomenon not seen at the beach for more than three decades. Scientists explain that the foam is created by impurities in the ocean, such as salts, chemicals, dead plants, decomposed fish and excretions from seaweed. All are churned up together by powerful currents which cause the water to form bubbles. These bubbles stick to each other as they are carried below the surface by the current towards the shore. As a wave starts to form on the surface, the motion of the water causes the bubbles to swirl upwards and, massed together, they become foam.

The foam ‘surfs’ towards shore until the wave ‘crashes’, tossing the foam into the air.

Whitewash: The foam was so thick it came all the way up to the surf club

‘It’s the same effect you get when you whip up a milk shake in a blender,’ explains a marine expert. ‘The more powerful the swirl, the more foam you create on the surface and the lighter it becomes.’ In this case, storms off the New South Wales Coast and further north off Queensland had created a huge disturbance in the ocean, hitting a stretch of water where there was a particularly high amount of the substances which form into bubbles. As for 12-year-old beach goer Tom Woods, who has been surfing since he was two, riding a wave was out of the question ‘Me and my mates just spent the afternoon leaping about in that stuff,’ he said.

‘It was quite cool to touch and it was really weird. It was like clouds of air – you could hardly feel it.’

Children play among all the foam which was been whipped up by cyclonic conditions.

Groceries at Sisters Island c. 1927 

– Elizabeth Kate (Stannard) Smithman (Wife of Henry Herbert Smithman who was Senior Keeper at Sisters Island 1927 – 1929) 

Light keepers have to take a four-month supply of food when they go on as there’s no way of getting anything otherwise. No stores to run to and no neighbours to borrow from, ha ha. The government boat called the lighthouse tender [probably the CCGS Estevan which was built in 1912] calls around every 4 or 5 months. Light keepers order groceries from wholesalers in Victoria and it is delivered to the government wharf and loaded on the tender and they bring it when they are coming up that way.

The Awfully Long Thermometer!

 In an earlier story I wrote about how the lighthouse keepers have been doing sea water samples since the early 1930s – some of the oldest observations on the BC coast!

Now, with satellites we can get different temperatures of the sea – Sea Surface Temperatures for one – similar to what the lightkeepers do, but globally.

Sea surface temperatures have a large influence on climate and weather. For example, every 3 to 7 years a wide swath of the Pacific Ocean along the equator warms by 2 to 3 degrees Celsius. This warming is a hallmark of the climate pattern El Niño, which changes rainfall patterns around the globe, causing heavy rainfall in the southern United States and severe drought in Australia, Indonesia, and southern Asia. On a smaller scale, ocean temperatures influence the development of tropical cyclones (hurricanes and typhoons), which draw energy from warm ocean waters to form and intensify. – NASA Earth Observatory Continue reading The Awfully Long Thermometer!

Ocean Water Samples

One of the duties of a lighthouse keeper on some stations, was to do a daily Sea Water sample. It was started very early on (see the story here), before the advent of Global warming, and the observed data has been beneficial in many ways as you will see at the bottom..

Kains Island (Quatsino) lighthouse

In the above-mentioned story from Kains Island lighthouse, the samples started in 1935, so we have seventy-seven (77) years of ocean data. Also in the story is the fact that in the early years . . . 

. . . the small glass bottles of sea water with cork stoppers were stored in wooden boxes with many little squares, one for each bottle1. These boxes would be shipped out when the supply ship re-supplied the station once a year, usually in July.  Continue reading Ocean Water Samples
