Geography in the News: Chernobyl Revisited (audio)

Subscribe to the Podcast

Chernobyl is a place known around the world. The meltdown at the Chernobyl power plant in 1986 made front-page news, and until Japan’s Fukushima disaster of 2011, was considered the world’s worst nuclear accident. With North Korea’s recent threats of a nuclear strike aimed at South Korea, Japan and the United States, the geography of Chernobyl’s impacts and the lessons learned are worth repeating to each generation.

How Do Streets Get Named?

Do you live on a road? Or a lane? Or maybe you live on an avenue? What’s the difference? Who decided whether your motor pathway is called a street or a boulevard? And how did it come to be boring “Maple Dr.” or too-clever “Tennis Ct.”?

As I can personally attest, there are millions of streets in the US of A.  Sometimes I feel like I have seen every one of them….on paper, anyway.  But there weren’t always so many streets here, and back when there were fewer, they were often named for the landmarks that they passed by, such as Church, or Market, or River.  They came by their names as a result of common usage and were almost always called “street”, a generic and suitable urban word, and usually not capitalized.  The landmark was the important factor, thus, “Court street”, or Hill street”.

Rural roads were generally not given official names.  Streets were commonly named for prominent statesmen like Washington or Adams.  Early in the 19th century a cultural phenomenon came into play wherein nature, formerly thought to be a wild adversary, began to be extolled over the dreary urban crowding that had come to exemplify city life.  Because of this, new street names took on all the Oak, Pine, Walnut, Elm, Beech, etc. monikers that fill so many maps.

As cities continued to grow, real estate operators were designing whole new neighborhoods and placing their own surnames, or those of their colleagues and financial backers, on the streets.  In the West, where entire towns might spring up at once, the checkerboard of streets commonly had letter or number assignments – easy to navigate, but uninspiring.  In the later 1800s, the suffix “Street” began to be supplanted by “Avenue”, a more upscale sounding term.  Similarly, towards the 1900s, the use of Boulevard, Park, Court and Terrace lent an air of the upper class.  As the automobile began its climb into the role of essential element of the culture, Drive was appended to more and more byways.

Into the 20th century, developers seeking to imbue their neighborhoods with a certain cachet, began to add “–wood” or “-stone” to the ends of innumerable root words.  Crossingstone, Bravestone, Griffinwood, Rainwood, and even…Stonewood.  The proliferation of housing developments in the last few decades has really strained the production of unique names, and the “namers” have stretched far beyond the names of flowers, universities, world cities, and animals.  I have seen neighborhoods of famous jazzmen, astronauts and racehorses amongst a host of others.

In the shot below, have a close look and see if you think the person who named some of these streets in Atwater CA may have been paying homage our fair city and county, however badly spelled.

Doldrums – Maps and Diagrams

Air in motion – it’s a constant and unstoppable feature of life on the Earth, given that the planet is endlessly spinning on its axis and variably warmed by our Mr. Sun.  Currents of wind flow in predictable patterns and you’ve all heard about the westerlies and the easterlies and the trade winds.  The trade winds, so called because they facilitated the merchant trade of the sailing ship days, blow between about 30 degrees north and south of the equator.  It’s hot at the equator, so as these two air masses meet, they heat up and rise, rather than blow across the surface.  In other words, it’s mostly pretty calm along the equator and if you’re trying to go somewhere by sail, you’re out of luck.

The Doldrums

Technically this belt, about 5 degrees on either side of the equator, is called the Intertropical Convergence Zone, or ITCZ.  Colloquially, it’s known as the doldrums, and given that the origin of the word points to the Old English “dol”, for foolish or dull, the word apparently referred to human mental stagnation before it was applied to the slack breeze in the middle of the tropics.  Bored, dispirited and overheated, sailors stuck in the doldrums could face illness and starvation.  Further aggravating their plight, the heat of the equatorial region can make for a lot of evaporation and humidity, which can lead to rapidly-forming storms.  Sudden 30 knot gales can be a bit too much of a good thing.

Horse Latitudes

In the neighborhood of 30 to 35 degrees north and south, the air that was heated along the equator descends and creates another belt of weak cross-surface wind.  Sailors becalmed in these regions were known to jettison horses and other livestock from their ships in order to conserve precious water supplies and lighten their load, and these parallels became known as the horse latitudes.  It’s no wonder the world switched to steam power for ships when it could – getting stuck in the doldrums or the horse latitudes brought delay and physical and mental anguish.

Here are a couple of diagrams illustrating of all this – each lends a different bit of clarity to the concept:

Disclalmer: I am not now, nor have I ever been a meteorologist and the above is my best distillation of some fairly complex heat and air physics.  No animals (except the horses and sailors) were harmed in the composition of this Geo-Joint and the author takes no responsibility for the reader’s use of this information.

Fog Harvesting in Western South America

People live all over the planet, but life is tough where there is little water.  Desert populations are low, unless you can import water, or suck it from ancient underground aquifers as has been done in Arizona and Saudi Arabia.  But even without the help of pipelines, water trucks, or drilling wells, some communities in lands of very sparse rainfall have found a way to get enough water to live comfortably.  Do you know how they get it?

It doesn’t work everywhere, but in some places that are certifiable deserts, there is a lot of fog. This is common along the coastal cliffs of western South America in parts of Ecuador, Peru and Chile where desert lands run all the way to the sea. Well, that’s nice, you may think, so you can be sort of damp all over while you die of thirst! But some clever thinkers realized that by erecting nets of very fine strands, heavy fog could be “trapped”, the condensate collected as it dripped down into trays, with the water thence flowing to pipes. Doesn’t seem like it would produce all that much water, but it does! For you guys with facial hair, think how wet your moustache or beard gets when you walk on the beach on a foggy day. Same principle.

Banks of fog nets have been a boon to poor communities that are far from water sources, or which have no funding to tap into the nearest urban supplier. While none of these towns will be constructing a water slide amusement park any time soon, a fog net system in one Chilean locale increased per-person daily water availability from just over 3 gallons of expensive trucked-in water, to as much as 14 gallons of far cheaper netted fog. People can take a shower every day, an unheard of luxury in the past.

So the next time you’re stuck with a problem you can’t seem to solve, remember that the solution may be all around you, blowing in the wind.

On the Map: Ellis Island

People enter the US of A at a great number of immigration stations in cities at our nation’s margins.  Despite the best efforts of the INS, many arrive through unnofficial portals.  But a vast number of newcomers passed through a particular point on their way into this country.

Ellis Island, by Jersey City, off the southern tip of Manhattan, was the home of an immigration station that opened in 1892.  As ships approached this small speck of land in the Hudson River, they passed by Liberty Island, home of the Statue of Liberty, and immigrants were no doubt awed, hopeful and probably a little scared at what lay ahead.

By 1892, the immigration patterns into the US were shifting from the English, Irish and Western European nations to the Southern and Eastern European lands.   Greeks, Poles, Slovaks, Hungarians and Russians were amongst the many people escaping wars, religious persecution and poverty.  The greatest wave of arrivals came between 1900 and 1914, when 5,000 to 10,000 people a day would be processed.  Legend has it that in this crush, many had their names changed or mangled by ignorant officials, but the truth of the matter is that passenger lists were compiled at the port of origin where there were people familiar with regional surnames, and incoming passengers were not accepted without proper ID.  Ellis Island inspectors were themselves often immigrants, and interpreters of many languages were on hand to clarify confusion.  Name changes did occur over time, but they usually resulted from poor documentation made by officials encountered later, such as business clerks or teachers, or because of the immigrant’s own difficulties with English.

Legal Examination in the Great Hall

Partly due to the huge influx of immigrants, laws were passed in the 1920s that limited the number of immigrants allowed from particular countries, and the overall total, so from the ‘20s til Ellis Island closed in 1954, there were far fewer entries.  Still, more than half of all US immigrants in that later period came through Elllis Island.  In all, more than 12 million citizens of foreign nations began their American experience at Ellis Island so it is little wonder that somewhere around 40 percent of all people in this country can trace their family back to a relative who passed through that famous gateway.

Gold Leaf Easter Egg Maps

Easter is just around the corner and we can’t help but share these clever gold leaf Easter egg globes by Sugar and Charm. Though these map eggs look difficult and time consuming, she assures they are not.

Using gold leaf glue, a paint brush and a pencil, draw your design. Paint it in with glue and then place a sheet of gold leaf over the top. Lightly tap it (it might lift, but that’s okay because you can fill the holes in later) and then give it a second before lifting the edges up. Your design will pretty much be laid in, but you’ll need to do a little touching up and cleaning around the edges.

If you’re finding yourself stuck in drawing the continents on the egg, here is a helpful world map to reference that will help you on your way.

Natural Maps: Recreated Coral Reef Art


Map art at its finest. Connecticut-based artist Amy Eisenfeld Genser recently completed a new series of coral reefs that she painstakingly recreates using rolled bits of paper and acrylic paint. Ahead of her upcoming exhibition at the Architectural Digest Home Show, Genser sat down with All Things Paper for a brief interview. An excerpt on her process:

These days I usually work with Thai Unryu [mulberry paper], but I have hundreds of papers in my studio from all around the world. I treat the paper almost as a pigment, layering colors one on top of the other to create different colors. My pieces are about a foot wide. Then I roll one layer on top of the other in all different thicknesses. I seal the roll with acid-free, archival glue stick, and then cut the long piece into sections with scissors or pruning shears. I have pruning shears of all different sizes to accommodate different widths.

Krakatoa – East of What???

Well, the first thing to fix on that movie title from 1969 is the spelling of “Krakatoa”, which should be “Krakatau”.  But more importantly, Krakatau is located between Java and the island of Sumatra, and it is decidedly west of, not east of, Java.  Guess “east” must have sounded more exotic to the Hollywood title creators.  But Krakatau is famous for more than being a movie star.  In August of 1883, in four huge eruptions, the Krakatau volcano which formerly stood about 2,600 feet high, blew itself to smithereens and set enormous tsunamis in motion that along with the eruption, killed an estimated 36,000 people.  The noise was so loud that it burst the eardrums of sailors miles away, and the sound was audible on Diego Garcia island, some 2,000 miles distant.   It may have been the loudest noise generated in human history.  News of the eruption was known far and wide in record time, because recently laid undersea telegraph cables sped up the reporting.  But people got other “news” of the blast as all the material blown high into the atmosphere caused very colorful sunsets worldwide for almost three years following the event.

That’s Sumatra on the northwest of the “A” pointer that marks Krakatau, and Java to the east.

Before the big bang

Krakatau in our times – it’s rebuilt itself, rising above the surface of the sea in 1927.  This new island is called Anak Krakatau, or “Child of Krakatau”:

Why do we have Daylight Saving Time?

Dragging a little bit today?  Sleep deprived, perhaps?  Maybe it’s the hour of sleep you lost a couple of days ago when we set our clocks forward for Daylight Saving Time.  What?  You forgot?  So that’s why you’ve been late to work for two days!  But seriously, do you know why we change our clocks twice a year, and the effect it has (or doesn’t have) on the nation?

Some people love that extra hour of sunlight at the end of the day, and others hate losing an hour of sleep and throwing the kids’ schedules all off, and wonder why we do it.  Obviously, it has to do with taking advantage of the natural lengthening of the day as our hemisphere tilts towards the sun in the spring.  Ben Franklin suggested it as a way to save on candles in the evening, but it was many years later, in 1918, that it became law for a year to help cut the use of evening electricity during World War I.  World War II saw the return of Daylight Saving for similar reasons.  But it wasn’t til 1966 that the Uniform Time Act established nationwide time change from the last Sunday of April to the last Sunday of October.  There have been a number of tweaks and adjustments to its length, but as of 2007, Daylight Saving Time was extended to begin on the second Sunday of March and end on the first Sunday of November.
Daylight Saving Time tends to be more popular on the western sides of time zones, where the effect of moving the clock up by an hour provides more evening light than on the eastern sides.  Farmers are amongst the naysayers as they already get up very early in the dark, and the time change exacerbates that.  Add to that the fact that farm animals don’t wear watches, and are thoroughly uninterested in changing their habits (such as milking time for cows) just because Farmer Brown adjusted his kitchen clock.  So given that the main practical reason for all this disruption is conservation, are we really getting a payback?  It turns out that while we do save significant electricity overall by pushing the dark back, people use that extra hour to do a lot of running around taking care of business or going to someplace to play, so the extra gas burned has a negative effect.  For many of those who just go home after work, there is an extra hour of running the AC, which further eats into the energy advantage.  But despite the debate over the energy savings, people really seem to get a kick out of that later light, so we’ll probably keep it up.  However, if you’re in the “hate it” camp, there is a solution!  You can move!  For reasons of excessive evening heat in Arizona, and greater proximity to the equator in Hawaii (thus little change year-round in daylight length), the advantages of daylight saving are diminished and the locals in those two states have voted not to observe the time change.

Fun fact:  The Navajo Nation (a significant chunk of NE Arizona), does change to Daylight Saving Time each year.  This is due to the fact that their large reservation extends onto two other states.  However the Hopi reservation, which is within the Navajo reservation, follows Arizona’s lead and does not observe the time change – yet another example of how complicated the world of time observation can be.
