2013 Tide Newsletter
The Metal Detecting Creed
By Jessie Thompson
We are Metal Detectorists. Venturing forth in search of relics lost to
time, only to be discovered and
secured for future generations.
Diligent in our endeavors to detect,
we will not trespass on to posted
lands and will always obtain lawful
permission in advance.
Detectorists are protective of
earth’s creatures, natures landscapes and tributaries. We close all
gates and leave no refuse in our
wake.
When requested, we will endeavor
to assist in the recovery of lost
items of sentimental value to the
best of our ability.
History being the tie that binds us,
any item recovered of a singular
significant historical value will be
reported to local historians.
Remember Metal Detecting is to be
conducted in a respectful and courteous manner; we are the ambassadors of our hobby to all who may
survey us.
Here is our first crack at creating a tide
newsletter for the year 2013. This information was collected from around the web especially the tide info from NOAA. While this
information provided is from a reliable
source we make no guarantee as to its correctness. Use at your own risk. We will try to
do this newsletter once a year. Please keep
it on your desktop for reference or print out
a copy. These tides are based on the Stamford, CT location.
PROXIGEAN TIDESThe Proxigean Spring Tide is a rare, unusually high tide. This very high tide occurs
when the moon is both unusually close to
the Earth (at its closest perigee, called the
proxigee) and in the New Moon phase (when
the Moon is between the Sun and the
Earth). The proxigean spring tide occurs at
most once every 1.2 to 1.5 years.

and occasionally by much more. What's more,
the low pressure characteristic of such
storms lifts oceans: A 1-inch drop in barometric pressure raises the seas by 13.2 inches,
which can cause a dangerous period of proxigean tides to boil over into a coastal catastrophe (It's also possible for only one of any
given day's two high tides to be catastrophic).
Proxigean tidal conditions combined with disastrous storms to bring death and calamity to
the eastern and southern United States in
1723, 1846, 1851, 1885, 1900, 1914,
1931, and 1978. The greatest loss of life—
6,000 people—occurred in Galveston, Texas,
on September 8, 1900. Low–lying regions of
Europe also have faced devastation when
such astronomical and meteorological conditions coincided: 100,000 people died in Holland in 1099, and half that many in 1287. –

The proximity of the Sun to Earth in December or January will occasionally coincide with
a new or full Moon that just happens to occur when the Moon is at its monthly perigee—or perhaps even when it's at the year's
most extreme perigee. This potent combination happened in 1990, 1992, and 2001.

This series of events can result in interesting but not necessarily destructive ocean
levels. The final devastating ingredient is a
storm at sea. The onshore winds of an
ocean storm can literally whip up the waters, typically raising tides by several feet

Earth experiences proxigean tides—an extraordinary tidal range that, when combined
with other factors (such as unusually low
barometric pressure or onshore winds), can
cause erosion on coastlines, among other
problems.

SPRING TIDES – PERIGEE (means closet to the earth) and or PERIGEAN TIDES are the same!
About three or four times a year (in the spring and the fall), the new or full moon coincides closely in time with the perigee of
the moon—the point when the moon is closest to the planet. These occurrences are often called 'perigean spring tides.'
A spring tide is a common historical term that has nothing to do with the season of spring. Rather, the term is derived from
the concept of the tide "springing forth." Spring tides occur twice each lunar month all year long without regard to the season. Neap tides ( Moderate Tides), which also occur twice a month, happen when the sun and moon are at right angles to
each other.
The following is a explanation of spring and neap tides in relation to lunar and solar cycles.
Since antiquity, people have noticed that oceans exhibit a much greater tidal range around the time of the full Moon and
new Moon. This is when the Moon and Sun are either together in the sky or are on opposite sides of the heavens. Higher
tides occur during these Moon phases because the Sun also exerts a gravitational pull on our oceans, although it is only 46
percent as strong as the Moon's.
When the gravitational effects of the Sun and the Moon combine, we get spring tides, which have nothing to do with the season of spring. The term refers to the action of the seas springing out and then springing back. These are times of high high
tides and low low tides.
A week later, during either of the two quarter Moon phases, when the Sun and Moon are at right angles to each other and
their tidal influences partially cancel each other out, neap tides occur, and the tidal range is minimal. In fact, because the
oceans take a bit of time to catch up to the geometry of the Moon, spring and neap tides usually occur about a day after the
respective lunar cycles. – Bob Berman

Q: What is the difference between "Tide Charts" and "Tide Tables"?
"Tide Charts" and "Tide Tables" are actually two different products.
"Tide Charts" refer to a series of maps that show the water levels throughout
a bay or estuary at a particular point in time. These maps normally show the
water levels on an hourly basis after high tide. "Tide Charts" are only available for a few locations around the USA.
