The Biospheric Ocean

The ocean is one of the five biomes within Biosphere 2.  The others are:  rainforest, savannah, desert, and marsh.  This view down onto the ocean shows a rowboat pulled onto the beach.

The ocean is a million gallons of saltwater, complete with fish and coral reef.  The beach in the foreground was a favorite picnic spot for the Biospherians.  The marsh is in the background.

The rainforest is at the top of the cliff.

In the Cloud Forest

One of my favorite areas of Biosphere 2 was the cloud forest.  Here, Laura disappears into the mist.

Biosphere 2 -- Part 1

The main reason Laura and I went to Tucson was to tour Biosphere 2.  We weren't disappointed. 

The most iconic part of Biosphere 2 is the huge greenhouse housing the rainforest.  After 20 years, the trees have nearly reached the top.  (What is Biosphere 1, one might ask?  The Earth itself.)

The dome on the right houses a "lung" -- a rubber membrane that expands and contracts to maintain a constant air pressure as the greenhouses heat up and cool off as the day progresses.  In the middle are the crew quarters.

An experimental solar panel array, testing different ground covers used when placing the panels directly on the ground.  I have mixed feelings about sacrificing a hillside like this.

I'll be posting more Biosphere pics when I have time.

One observation:  Biosphere 2 emerged from its 1991-93 mission with a bad reputation.  The most common themes are "a failed experiment," and "bad science."  But we need to remember that this negativity was created by the corporate media, which as we all know is as corrupt as any other national institution.  Members of the corporate media, especially at the national level, tend to be shallow, snide, and self-important.  We don't need to take their opinions seriously. 

San Xavier del Bac

Here's a typical tourist picture of the San Xavier del Bac Mission, probably the top tourist destination in Tucson.  The mission was founded in 1699, and the present church was started in 1783.

I have always had a connection with Tucson, going back to my five months in 1971-2 when I worked for the Lunar and Planetary Lab at the University of Arizona.  I hadn't been back to Tucson for a number of years and had never shown San Xavier to Laura, so this winter seemed like a good time to return briefy to "The Old Pueblo" as Tucson is sometimes called. 

The altar, and in fact the entire interior, is very ornate. 

Candles in an adjacent shrine room made a nice pattern picture.
