Okay I am a smoker. I smoke outside (laundry room is a cross between outside and inside - and this is where I smoke). I usually take my laptop with me so I can continue to chat with you ladies. So I go in the laundry room. Open the door to outside to ventilate the room. Grab a cigarette, light it (all while holding onto my laptop). Then I go to sit down. And miss the chair by a foot.

Hahahahhahahaha... That's great. So did the cherry fall off?

Nope! AND I didn't drop the laptop.

I'm suddenly sooo tired. It just went WOOMPH and hit me all at once.
I'm off to bed. Goodnight!

Oh, and btw, I just wanted to let you guys know that when I say that I love you, I seriously mean it! I haven't even been posting that long and I feel so close to you guys. It's awesome.

G'nite!

considdy. is. leaving. meeeeeeee?



have a great night!

she moves like sea breeze...

oh somebody please get this song out of my head!

Chelsey is leaving too...

My bed looks so heavenly right now.

I just have to somehow get the 20lb bitch off my bed...

Oi.

I want you to want me...
I need you to need me...
I love you to love me...
I'm begging you to beg me...

Good night ladies

everyone is leaving!!!! noooooooo

it sucks, cuz I have to leave too.

I have so much homework.

Awwww, if I could help I would.

Oh, fyi... 20lb bitch= Sammi the cat.


Chyeah... I'll be lurking for about 5 minutes now..

Goodnight!

I was wondering about that

In the last lesson we covered the wind-driven currents of the surface ocean. While the surface circulation is the more obvious to us, it turns out it affects only 10% of ocean water volume. The remaining 90% of ocean water is too deep to be affected by wind. This lesson covers where that deep water comes from, and how it circulates through the deep ocean in slow currents driven by density differences between water masses with different temperatures and salinities. This slow movement of deep water helps regulate our climate, and delivers nutrients to organisms living in the deep.


Density-Driven Water Flow

Deep-water circulation is driven by density differences (as in heavier water sinks, and lighter water rises), and is called “Thermohaline Circulation” because temperature and salinity (T&S) together are what determine the density of seawater. Processes that cause variations in temperature and salinity occur mainly at the surface (warming and cooling by the atmosphere, evaporation, freezing). So once a parcel of water becomes dense and sinks away from the surface it tends to keep its T&S characteristics for a long time (1000 years or longer), until it eventually circulates back up to the surface.


Density Variation in Sea Water

Most ocean water is within a narrow range of T&S. The figure below (Figure 6.13 in your textbook) shows the natural range of T&S of ocean waters. 75% of ocean water has the very narrow range of T&S characteristics covered by the small, dark blue square near the bottom of the figure at 0–5°C and 34–35‰, while 99% of ocean water has T&S characteristics that fit within the light blue area. But even these small variations in T&S are enough to create the density differences that drive deep-water circulation.
