Use the space below to reflect upon our recent study of the physical components of the ocean (often referred to as simply "oceanography").  Direct your work below to the reality of tides, currents, waves, and perhaps even the general nature of the world's oceans.  Also be certain to pay attention to the elements that make a good reflection, or argument.  Ask yourself as you construct your response here:  "does my contribution here extend or deepen the discussion as a whole?"  And as always, metacognition is key.  Uncovering your thinking at each step along the way is a very effective strategy for learning.
Also, in the thread below, add in a resource that you found on your own that helps not only you... but will also potentially help extend the understanding of your classmates.  This additional resource might be an excellent image...

...that helped your understand of one or more of these concepts.  Perhaps it is a link to an entire webpage devoted to one of the topics.  (This link goes to a really cool children's book about the spilled plastic duckies that taught us a thing or two about ocean surface currents.  Try reading it to a little sister, cousin or neighbor.)  Maybe even a videoclip that does a good job of helping you visualize some of the more abstract concepts, or even takes your learning in directions you hadn't even foreseen...


Whatever you choose, do it up right in the space below...

this website has grate resources that helped me understand oceanography better. i now know more terminolgy about currents, waves, and tides!!: )
Yes... that really is a super resource. Nice find. It is in my list as well. So what about your learning in this area? Check out the first part of the prompt about and flesh out your thinking a bit. What surprised you? What wasn't perhaps immediately clear? What made those things ultimately understandable to you? Had you been previously exposed to this field of information... or was this more or less a first exposure? Explain a bit more of what you now know, what you might not be perfectly clear about, or would want to know more about. Try to challenge yourself to reflect and truly make your thought processes transparent to the rest of us...
while reading on this website
i discoverd interesting things about the ocean. even though i already knew about how dolphins use sonar to comunicate and "see" , i had no idea how fast sound travels in water! apparently it travels 4,750 to 5,150 feet per second!!!! whats even more amazing is that the time that sound travels in water increases by seven feet per second whenever the temperature increases by 1 degreee F!!!!!!!!
im LOVING this website because it is soo informative on anything you would want to know about the oceans! :)
I knew about the sun and moon and how they affected the tides but I didn't know about what the ocean was made up of. The fact that the ocean has so little salt content compared to the chloride, sodium, sulfate, magnesium, calcium, potassium, and bicarbonate but can still taste so salty amazes me! I didn't know about gyres, as amazing as that sounds, and I also didn't know how they collected data from the ocean. I didn't know that The North Atlantic Current or The Gulf Stream existed but I can definitely now see how their can be different animals in different oceans and how they can have adapted to the different currents, weather patterns, and the different environments created. Scientists pay a lot of attention to the little parts and pieces of our oceans. I didn't know their was so much data being collected still today. I read somewhere that we know more about the surface of mars than we do our own oceans. While keeping this in mind I also know that 43% of all statistics are made up on the spot, probably including this one, but I believe that the mars thing is true and I think we should pay more attention to our surroundings. I also know that we have just discovered the Colossal Squid and several other species in our oceans. I have also studied wavelengths before but going over them was a nice refresher. I have one question though. Are there currents deep, deep in the ocean?

Really Ccool picture for the Coriolis Effect.

Click here for an awesome website full of small facts about the ocean.

This Video is really boring but it does help with the difference between spring and neap tides.

Currents exist at all depths in the ocean. There are much colder currents that travel below the warmer currents near the surface. Although the current system is complex, ocean currents are driven by two forces: the Sun and the rotation of the Earth. :)
It is pretty interesting that in one part of the ocean dolphins exist, and in another polar bears. Without the vast climates on earth, many living organisms wouldn't exist. That's another interesting part of this class, we're able to learn about all these differences and their affect on the Earth as a whole.
I found a diagram that shows another perspective on spring and neap tides that I thought helped me get a better grasp on the differences between tides. Even if you already understand, this is interesting to show a detail we don't usually cover when learning about the general concept of tides; just what the highs and low really are.
When people start talking about waves, tides, and currents; I start thinking of the moon. The moon is constantly in motion and our oceans are too. They kind of connect in that way. The ocean is in movement though because the moon is pulling on it. The picture I attached shows the us the temperature's of the oceans. I bet your wondering what temperatures have to do with waves and such. Ill tell you; It gives us observations about the speed and direction of currents and about the heat stored in the ocean, which will help us predict global climate variations! Other reasons are color variations, sea height, and winds. Tools they use to measure the currents, tides, and waves are buoys, drifters, and satellites. For those of you who do not know these terms ill explain. Ocean currents are continuous, directed movement of ocean water generated by the forces acting upon this mean flow, such as breaking waves, wind, Coriolis force, temperature and salinity differences and tides caused by the gravitational pull of the Moon and the Sun. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. Waves travel and transfer energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport. They consist of oscillations or vibrations around almost fixed locations.

This website is WONDERFUL!! It helped me learn a lot, and I learned who discovered what!
I learned about the moons connection to the ocean as well! I found out that the side of the Earth that is closer to the moon has a higher water level because the attraction is greater. When the moon and sun are on the same side of the Earth the tidal stream is much stronger.
WOW! thats really cool , i wonder why the attraction is greater on the side of the Earth that is closer to the moon, and why is the tidal stream stronger when the moon and sun are on the same side as the earth!
I think this

photogragh will help with the better understanding of the moon and sun gravitional pull on the ocean.
Back in elementary school I remember learning that the moon effected the tides on Earth, but that's it. Whenever we began talking about this in class, I realized there is so much out there about the ocean that I DIDN'T know and that I didn't even know existed. It's so weird to think that about 2/3 of the Earth is covered by water, but most people know nothing about it. this site really helped me with all things about the ocean. It amazed me that the wind TRANSFERS some of its energy that causes waves- the stronger the wind the larger the wave. I clicked the link at the top to find out why the ocean is salty- water picks up small amounts of minerals from river beds and flows into the oceans and seas. One cubic of water contains about 2.2 pounds of salt. I remember when I went to Hawaii in '08, salt water from the ocean got into my mouth. Knowing what I know now, there was quite a bit of salt in my mouth at that moment. Gross.

Island Time

Living on Island TimeThe first couple of days were spent waiting on this and on that and it truly felt like a year had gone by.  The first day was spent waking up early and driving to KCI airport where after about an hour or so of waiting we finally got on the plane that took us to Florida.  I sat in the very back of the plane with Zach and McCabe and I learned a valuable lesson from Zach when you get your free drinks on the airplane "always ask for the can".  The next morning we split into…See More

A New Experience

I woke up early and went to meet everyone at the library. Once we got our passports and tickets we all headed to the airport. We took a flight to Ft. Lauderdale.  Once there we all we out to eat and I had a Mahi-Mahi sandwich and tried some oyster, steamed clam, and calamari.  I think out of those 3 I will only have the calamari again.  Then we got our rooms and got the information for the plane trip to Andros.  We had the rest of the night to ourselves and I went swimming and hung out in some…See More

Loving the Bahamas!

I have known that I wanted to this program for a long time now. My brother did it back in 2003. I saw how much fun he was having learning the fish and then going out on the sail boats and seeing them in person. I saw what he brought back from the trip and it all sounded like so much fun i just had to try and go. So here I am! I took the class and went on the trip.Day 1 I couldn't sleep, I had to be up at 4:30 in the morning so we could meet at the library and and be at the air port around 6:20…See More

Time of my life!

Plane ride to Andros     My group got here 2nd and right once we got to Forefar we ate lunch and then got in the water.  I was ready to get right in and I saw so many fish.  Shelby Mills and I went snorkeling together.  The first fish we saw was a Beaugregory Juvenile.   Then we saw a sea slug.  It had orange and blue stripes going down its back.  Then we also saw an adult Beaugregory.  The next fish was a cocoa Damselfish.  This fish has a blue color on top ends and a dark spot on the upper…See More

Aye, Mon! (a.k.a. My Bahamian Experience/Greatest Week of 2013)

Where do I even begin? Or better rephrased, how do I start telling the tale of the most intriguing adventure I've ever gone on in my short 17 years of life? The most obvious answer would be to start with Day 1, which is only logical, but once you've started reading my account, I think you'll understand why I didn't know where to begin. Day 1- Friday, March 21st, Saint Joseph to Ft. Lauderdale Boy, I definitely wished I was a morning person that day. We met at a parking lot at East Hill's mall…See More

The Bahamian Experience

Everything about the Bahamas was pretty much perfect. The weather, the people, the lifestyle, the water, the air, the night sky, and the people. Did I say people twice? Heck yes I did because the people truly were some of the coolest people ever.They were some of the most down to earth and friendly people I have ever met. There was even a statue of a pair of hands shaking to really reinforce the fact that they were very friendly people.The first day that we spent on the island I played some…See More

Under the Sun-2013

Saturday, March 23rd, 2013Yesterday we arrived at Ft. Lauderdale, Florida to begin our adventure miles from home. Around 12:30 PM, 7 of us loaded a small plane with a pilot named Eddie (I got to be co-pilot!) and we set flight over the ocean. The ocean is simply breathtaking and magnificent. Looking the 5,000 feet down to the shades of blue wasn't full of much to look at but I couldn't take my eyes off of it. I was looking for something to strike my eye, to jump out of the water...SOMETHING!…See More
