Did You Know
– The Chesapeake Bay is an estuary: a body of water where fresh and salt water mix. It is the largest of more than 100 estuaries in the United States.
– The Bay is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia.
– The Bay’s width ranges from 4 miles near Aberdeen, Maryland, to 30 miles near Cape Charles, Virginia.
– The Bay is surprisingly shallow. Its average depth, including all tidal tributaries, is about 21 feet. A person who is 6 feet tall could wade through more than 700,000 acres of the Bay and never get his or her hat wet.
– A few deep troughs run along much of the Bay’s length. Some of these troughs are as much as 174 feet deep. The troughs are believed to be remnants of the ancient Susquehanna River.
– The blue crab’s scientific name — Callinectes sapidus — translated from Latin means ‘beautiful savory swimmer.
– Blue crabs not only comprise the most valuable fishery in the Chesapeake Bay, but are major predators of benthic communities and are prey for many other fish species.
– Blue crabs are sexually dimorphic, meaning sexes occur in distinct forms. Males have blue claws and a narrow abdominal apron (referred to as the Washington Monument). Females have red-tipped claws (“painted fingernails”) and a broad abdominal apron (referred to as the Capitol dome).
Thomas Point Shoal Lighthouse
– Location: Chesapeake Bay just north of the mouth of the South River, south of Annapolis, Maryland
– Date Built: Original shore light – 1825, Re-built shore light – 1840, Current screw-pile – 1875
The current Thomas Point light is arguably the most widely recognized lighthouse in Maryland and is the only screw-pile light on the Chesapeake Bay still in its original location. (The remaining 3 have been moved to museum settings.) It is the third light to mark Thomas point shoal.
The lighthouse was manned until 1986 and was the last lighthouse on the Chesapeake Bay to be fully automated. More recently, its image was a runner up for Maryland’s back of the 2000 U.S. quarter coin.
The Bahamas, 700 islands and 2,400 cays, dot the Atlantic Ocean from Florida almost to Haiti. Only 30 of the islands are inhabited.
Today, about 85 percent of Bahamians are of African heritage. New Providence, one of the smallest of the major islands, is home to almost 70 percent of the population. The Bahamas takes in more than three billion dollars annually from nearly four million tourists. International banking and investment management augment the economy, with more than 400 banking institutions from 36 countries.
Capital: Nassau; 222,000
Area: 5,382 square miles
Language: English, Creole
Religion: Baptist, Anglican, Roman Catholic
Currency: Bahamian dollar
The circumnavigation of Eastern North America by water is known as The Great Loop. Also improperly referred to as the Great Circle Route.
The trip varies from 5,000 miles to 7,500 miles depending on the options used.
The boats used range from personal watercraft (jet-skis) to 60-foot yachts. Both sailboats and powerboats are used but the most common boats are 34–45 ft recreational trawlers. The main factors that govern the size of the boat are the limited draft (5 feet) in some locations on the loop and the height of one bridge (19 feet) in Chicago.
People traveling The Great Loop are known as “loopers.”
The number of people attempting this voyage is growing with the baby boomers reaching retirement age. In 2007, more than 150 boat owners notified America’s Great Loop Cruisers’ Association that they were planning to attempt the loop in the coming season.
The Abacos are a group of islands and cays forming a boomerang-shaped 120-mile-long island chain that stretches over 650 square miles. Geographically, The Abacos are simply ideal for boating and sailing. Great Abaco’s coastline is scalloped with bays and coves and protected harbors that feature full-service marinas and resorts. Great Abaco Island and Little Abaco serve as the “mainland,” with a string of barrier islands separating them from the Atlantic. The body of water between – a turquoise nirvana for those boaters and sailors – is the calm, shallow Sea of Abacos.
Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning
In order to understand why “Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning” can predict the weather, we must understand more about weather and the colors in the sky.
Usually, weather moves from west to east, blown by the westerly trade winds. This means storm systems generally move in from the West.
The colors we see in the sky are due to the rays of sunlight being split into colors of the spectrum as they pass through the atmosphere and ricochet off the water vapor and particles in the atmosphere. The amounts of water vapor and dust particles in the atmosphere are good indicators of weather conditions. They also determine which colors we will see in the sky.
During sunrise and sunset the sun is low in the sky, and it transmits light through the thickest part of the atmosphere. A red sky suggests an atmosphere loaded with dust and moisture particles. We see the red, because red wavelengths (the longest in the color spectrum) are breaking through the atmosphere. The shorter wavelengths, such as blue, are scattered and broken up.
Red sky at night, sailors delight. When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.
Red sky in morning, sailor’s warning. A red sunrise reflects the dust particles of a system that has just passed from the west. This indicates that a storm system may be moving to the east. If the morning sky is a deep fiery red, it means a high water content in the atmosphere. So, rain is on its way.
Rainbows are simply beautiful multicoloured arcs of light in the sky. Rainbows occur when it’s both raining and the sun is shining simultaneously. To see a rainbow, you must stand with your back to the sun, otherwise it will not be visible.
Our sun gives off light, which we see as ‘white light’. But in fact, it isn’t actually white at all, it is actually numerous different colour wavelengths. The main colours it gives off are red, orange, yellow, green, blue, indigo and violet. These colours are called the colours of the spectrum. This is often remembered by the mnemonic ‘Richard Of York Gave Battle In Vain’.
As an experiment, you can use a prism to separate these seven colours of the spectrum from the white light we see.
