Title: Oceans

Oceans
  • By Alicia Ellis

2
Oceans In General
  • An ocean is a large mass of salt water. An
    ocean can have very extreme weather conditions
    and if you dont know what youre doing while
    exploring you could be injured very easily. If
    you are planning to explore the top an ocean you
    would need a boat or something that would float.
    If you are planning to explore underneath the
    oceans surface you will need more tools because
    there is no air underwater and you wouldnt be
    able to breathe.

3
Where Im Researching
  • I am researching the Depths of the Pacific
    Ocean along B.C.s coast.

4
What I Am Researching
  • What I will be researching is ocean currents. I
    think that ocean currents would be interesting to
    research because even though sometimes if the
    oceans surface is completely calm, if you get
    into a part in the ocean that has a current it
    could be as violent as if there were waves on the
    surface. I want to know why those parts of the
    ocean dont apply to the rest of the ocean.

5
The Climate Of An Ocean
  • An oceans climate varies, depending on where
    on the Earth the ocean is. Generally where we
    live an ocean will be fairly cold. That
    temperature could change depending on the
    weather. In polar regions the ocean there is
    always cold, and most of the time the surface of
    the ocean is frozen. Near the equator and tropics
    the ocean is generally warm. That is because the
    ocean is so close to the hot equator and the sun
    usually beats down on the ocean every day. Even
    though In some places The ocean is generally hot
    or cold, near the bottom of every single ocean in
    the world (no matter where it is located) the
    ocean there is cold, dark, and still. There is no
    type of weather in the depths of an ocean but on
    the surface the weather can vary from light waves
    to waves as high as a house.

6
Are Oceans In Canada?
  • Yes there are more than 1 ocean that touch
    Canada , they are the Pacific Ocean (North
    Pacific), the Atlantic Ocean (North Atlantic),
    and the Arctic Ocean. The Pacific touches the
    West side of Canada. The Atlantic touches the
    East side of Canada. The Arctic touches the North
    side of Canada

7
The Conditions That Make It Difficult To Survive
In An Ocean
The most Obvious condition is the lack of air.
Humans arent built to get the dissolved oxygen
out of the water like fish and other marine
animals can. You can get around this condition by
using an oxygen tank or any other external source
of air. Another condition to exploring oceans is,
even if you have enough air to last a long time
there is the water pressure to take into
consideration. You can use a submarine to get
lower in the ocean than you could with just your
body because the submarine would protect you from
more water pressure. But even a submarine has its
limits and would eventually break. Ocean currents
are also an condition to exploring an ocean. If
you dont know where to go in the ocean you could
be tossed around for forever.

8
Obstacles To Exploring Oceans
  • Another obvious obstacle would be the danger of
    ocean animals. Even though shark attacks dont
    happen often they still could. There are also
    other animals that could hurt you, like
    jellyfish. Some of the most small jellyfish could
    kill you in under a minute. Another obstacle to
    exploring an ocean would be the possibility of
    your equipment breaking. Lets say you were
    traveling in a submarine and parts of the wall
    springs a leak, if the water fills up the
    submarine you will die. 2 more obstacles that has
    to with equipment are, lack of equipment, and the
    prices of equipment. If you dont have enough
    money to pay for your equipment you obviously
    wouldnt be able to explore an ocean. Some of the
    conditions mentioned in the last page would also
    apply here. Those conditions would be, lack of
    air, and ocean currents.

9
Why Oceans Are Important To Research
  • If we research oceans they will become more
    safe for us to travel on and in. If we didnt
    know anything about oceans there would be way
    more shipwreck occurrences around the globe. If
    we research and explore the ocean we will know
    more about I and therefore it will be a safer
    place for us humans to sail on or swim/dive in.
    The ocean effects the climate of the Earth
    drastically so if we know how the ocean is doing
    we can make a sensible prediction on how the
    Earth will change in the next few years. Another
    reason to research oceans is that children need
    to be educated and if we know more about the
    ocean adults can expand childrens knowledge on
    the ocean.

10
What To Use To Explore Oceans And How These
Things Work
  • If you want to explore the surface of the
    ocean you would usually use a vessel. Vessels are
    vehicles that explore the top of the ocean. Some
    vessels can be very big, like a cruise ship. Or
    Vessels can be as simple and as small as a row
    boat. Vessels can be powered by motors or by you
    rowing it. There are other ways to power a vessel
    but Im not going to list them all. If you want
    to explore the ocean depths you would have a
    couple different options. One of those options is
    a submersible vehicle. (SV.) A SV is a vehicle
    that explores under the ocean. An example of an
    SV is a submarine. Not all SVs have to be able to
    hold people though. A ROV (Remotely Operated
    Underwater Vehicle) ROVs Are controlled by a
    remote control and are designed to go about 3000
    underwater, where a human would have been crushed
    because of water pressure. ROVs are connected to
    a cable that is connected to a vessel where the
    person with the remote will be controlling the
    ROV. A ROV can be used for a whole bunch of
    different purposes. A few of these are,
    collecting information about the deep sea,
    discovering different types of sea animals and
    much more. Another option for exploring under the
    ocean would be to use a scuba suit. If the
    conditions are good enough that the human inside
    of the suit will not be hurt a scuba suit can be
    very helpful. With the suit the human inside will
    now be taking possibly more accurate
    observations. You will also get to see the ocean
    firsthand other than through a camera from a ROV
    or another kind of SVC like a ROV.

Who Has Explored Oceans Before
  • One very famous ocean explorer was named Jacques
    Cousteau. Jacques was born in France on June 11
    1910. He died in June 25 1997 at 87 years old. A
    lot of what we know about the ocean is because of
    his studies. He was a French naval officer,
    explorer, conservationist, filmmaker, innovator,
    scientist, photographer, author and researcher
    who studied the sea and all forms of life in
    water. He co-developed the Aqua-Lung, pioneered
    marine conservations and was a member of the
    Académie française. Some of Jacquess
    accomplishments he maded when he was alive are
  • -Inventing the development of the first
    watertight 35mm still camera
  • -Inventing self-righting underwater sleds
    for filming in deep water
  • -Designing the modification of torpedoes
    to be used as underwater scooters
  • -Inventing the first SCUBA (Self Contained
    Underwater Breathing Apparatus) regulator

12
What Canada Has Done To Develop Technology Used
For Exploration
  • In port Coquitlam BC there is a company called
    ISE (International Submarine Engineering) At ISE
    they dont necessarily make submarines, they make
    ROVs, AUVs (Autonomous Underwater Vehicles) and
    other Submersibles. In St. Johns, Newfoundland
    And Labrador there are over 50 ocean technology
    companies. Those companies are vital to
    Newfoundland And Labradors economy. There are
    also other places in Canada that contribute to
    ocean technology but at the moment I am not going
    to list them all.

13
How You Can Explore Oceans Safely
  • If you are planning to explore the surface
    some ways that you can explore an ocean safely
    are by not using a boat that requires too much
    fuel, that would pollute the waters. You could
    also use a boat that doesn't make much noise,
    that would disturb wildlife. If you are planning
    to explore the oceans depths you can use
    submarines that arent too big. If it breaks it
    would be a huge mess! You could also not use any
    environmental hazardous equipment like, a scuba
    suit, a scuba suit wont have any equipment on it
    that would endanger oceans there fore not being
    hazardous. You could also just not use any
    equipment at all. Some people do explore Oceans
    without any equipment, they are called Free
    Divers.
