100
A wind blowing from west to east

Westerlies

100

These currents are driven by a difference in heat 

Convection currents

100

What's gives water the "magic" ability to dissolve compounds?

High polarity breaking apart dipoles

100

This type of margin is characterized by a narrow shelf

Active margin 

100

Why is the ocean blue?

Light penetration

(red is the shallowest, blue is the deepest) 

200

These east-to-west winds are focused at the equator

Trade winds

200

Maximum gravitational attraction between the sun, earth and moon pull the ocean to form

King Tides

200

This feature of water gives it high surface tension and heat capacity

Hydrogen bonds

200

The name for the path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes 

The ring of fire

200

Traditional combination of probes to determine properties of seawater

CTD (Conductivity-Temperature-Depth)

300

In the southern hemisphere, winds in a counter-clockwise pattern are referred to as this 

Anti-cyclonic 

300

A water feature largely occurring on the west coast of continents, resulting in higher nutrients

Upwelling
300

While both important, does temperature or salinity have a larger effect on ocean density? 

Temperature

300

The three main sediment types on Earth

Terrigenous (land)

Biogenous (biology) 

Lithogenous (rocks)

300

A researcher might use a EA-GCMS to evaluate these properties of C, N, or O

Stable isotopes

400

In the Northern Hemisphere, anti-cyclonic wind results in this oceanic feature

Downwelling

400

The three biggest abiotic factors in intertidal environments

Temperature 

Water level

Oxygen 

400

A water mass with temps ~35F and salinity ~34.6 psu

Antarctic Bottom Water (coldest and freshest) 

400

Formed from chemical reactions between seawater and minerals

Hydrogenous sediments

400

What compound has a concentration depth curve INVERSE to oxygen? 

CO2 (carbon dioxide)

Respiration and photosynthesis are generally inverse 

500

The planetary phenomenon controlling water movement on Earth

Coriolis Effect

500

This ocean feature flows northward along the coast of Japan 

The Kuroshio Current

500

The half-life of radiocarbon-14 is 5730 years, what fraction remains after 11460 years? 

1/4

After 5730 years, 1/2 remains

After 2(5730), 1/4 remains

500

Skeletal remains of microscopic organisms make up more than 30% of the sediment 

Ooze (silicious or calcareous) 

500

Why is surface water "younger" in the Pacific than in the Atlantic?

Deep water is formed in the North Atlantic, Deep water is upwelled in the North Pacific
