Artifical Reef Awareness Understandng the Texas Gulf: Planning Dives with Moon phases & Tides..
The Texas Gulf can be fun and
relaxing if the Moon and Tides are made part of the DIVE PLANNING.
The moon has 21 days to its rotation around the earth. The angle of the
earths axes determines the gravitational pull of the moon on the surface
waters.
If near the equator,
polarity is small, however if you are far north like Iceland the tidal
currents can be very high and strong. The change in seasons is a result
of the earth rotating on the axes and results in changes in the tidal levels.
The Moon's angle to a region or body of water and the phases of the
moon, determines the time length and strength of a tide change. Some
days there are two to five tide changes in a day. The time length between
changes and the amount of water exchanged will determine the currents Underwater
and the visibility one could expect.
In The Gulf of Mexico
of Freeport and Galveston tidal currents can be moving one direction on
the surface. This is the affect of winds blowing over the surface creating
the surface current. Next is the gulf stream current which move northward
and easterly trying to return to the Atlantic Ocean. This specific current
changes the most in the Spring time. Next is the true tidal current on
the bottom and results in the change in visibility the most. If the strength
of one current is higher than the others, it will result in a very strong
current in the whole water column. This is why the gulf rig and wreck diving
off the upper Texas coast can play tricks on the unsuspecting diver. Dive
s which are best are in third quarter, this does not mean other days
can't be good. This means the 16th day of a moon phase usually results
in the whole water column having the least amount of suspended particles
and visibility is greatest.
