One of the massive body of water which is second only to the great Pacific sea is the
Atlantic Ocean. It is estimated that it wraps twenty percent of earth's faade with an area of
106 million square kilometers. This tremendous body of water maintains an approximate
354,700,000 cubic kilometers of sea water while various rivers from the nearby places run
into the Atlantic. This particular area is being regarded as the saltiest which could reach up to
37 parts per thousand by mass in terms of salinity and this is influenced by season, and
latitude, while the temperature which is also affected by season and distribution of sun's
energy can reach below -2 C.
Apart from the general information, the Atlantic is also a home to numerous types of fish.
Many experts consider this part of ocean as one of the world's richest fishing resources. The
cod, haddock, hake, herring and mackerel are some of the marine organisms caught here.
These creatures are frequently found in the nearby banks of New Foundland particularly in
the Grand Banks and there have been sightings also in Nova Scotia and Bahama Banks.
What's more, commercial fishers with their big transport vessels frequent this place because
there are an abundance of other invaluable sea organisms like lobsters and crabs. On the
other hand, individuals or groups are also found here angling deep sea creatures of the
Atlantic for leisure or sport. For instance, Striped bass are plenty in this area particularly in
bays of New York, Rhode Island, Virginia and New Hampshire are being fished by anglers for
recreation. As a result, several management methods were introduced such as size limits,
commercial quotas, and biological reference points for the well being of one's species
because their quantities are dwindling stemming from its attraction amongst recreational
anglers and industrial fishers.

As of today, the population of Striped Bass is on the rise due to the efforts of authorities and
also responsible individuals which showed great concern for the ecology within the Atlantic
Ocean.
In conclusion, the Atlantic Ocean is truly a magnificent piece of water ideal for recreational or
commercial fishing.
One particular valuable phase in fishing certainly is the operation of tracking down the perfect
places to angle. This is difficult to accomplish most of the time especially when you lack the
proper tools to do it. In the past people rely on experience and accounts by other people
which is why some sea areas today have become common grounds for fans and commercial
fishers. However our planet is changing constantly and what might have been the usual
practice in the past may not be applicable today.

2. In order to accurately locate areas where there is an abundance of marine organisms, an
individual must consider several factors apart from relying on history or accounts from other
people. Temperature of the ocean for occasion, contains a immediate effect on the creatures'
habits. Fish are cold blooded animals and they need cold water in order to survive. One more
aspect to take into account is the local creatures preferred food. This can turn out to be quite
a challenge because this step needs more than just visual observation. In this step, you need
equipments that would look for the food and not the fish. Locating the sources of food will
also show you where the sea creatures live. One specific tool which is very useful in finding
food is the chlorophyll chart.
Chlorophylls in the water are generally produced by plankton and these planktons are eaten
by small creatures which in turn are eaten by large fish and other marine animals.
Understanding the date provided by the chart will be the main in finding out the worth of
chlorophyll charts.
Upwelling in the ocean is very common and this is characterized by rising of cold water while
the warm water sinks to the bottom. When upwelling transpires, the vitamins below are
pushed upward causing a rise in the populace of algae and phytoplanktons. The number of
plankton multiplies which is then eaten by small creatures; this critters are eventually eaten
by minnows.

In conclusion, these minnows are the source of food for bigger maritime animals. Looking at
the chart, you can find areas with high concentration of chlorophyll as represented by
yellow/red color in the chart while the blue ones are regarded as clean water with less
chlorophyll concentration.
