This Day of the Year

  • Eight-Years Ago Today. Backyard Urban Garden in St. Petersburg, Florida.

    A Pineapple growing in my parent’s backyard urban garden. When I worked at the produce department at Publix, the manager told me that I could grow a Pineapple from the tops of the fruit we cut off and would have discarded. It would take a couple of years for the plant to grow big enough to produce the fruit again. Somewhere else I learned that calcium carbide can be used to induce flowering in one year old plants. The calcium carbide reacts with water to produce acetylene gas which is similar (but not the same) as ethylene.

  • Thirteen-Years Ago Today. Backyard Springtime Nature in New Jersey.

    At first, I thought this Question Mark Butterfly was a dead leaf. Then it started moving along the old deck railing. It is very well disguised or camouflaged as a dead leaf although more so for in the fall, not the spring when most leaves are green. If you look closely, you can see the tiny white question mark on the back wing.

  • Twelve-Years Ago Today. Semester at Sea, Spring 2013 Enrichment Voyage. Baltic Sea.

    Noctilucent Clouds viewed from my cabin on the MV Explorer while traveling from Stockholm to Copenhagen while crossing the Baltic Sea. Noctilucent clouds are high-altitude clouds that appear as glowing blue or silver streaks in the night sky, typically visible during summer months at high latitudes (or winter months in the southern hemisphere). They are tiny ice crystals illuminated by the sun below the horizon and only visible from the ground during astronomical twilight.

  • Twelve-Years Ago Today. Semester at Sea, Spring 2013 Enrichment Voyage.

    Sailboat passing in front of the setting sun viewed from the deck of the MV Explorer on the Baltic Sea. For several voyages we have been having a contest to capture images of ships passing in front of the rising or setting sun while at sea.
