Oceanography Mid-Term Study Guide (Fall 2011):
Tuesdays 11am-145pm & 625pm-910pm

Overview:
BATHYMETRY CONTOUR MAPS
-Know how to draw contours, be aware of contour intervals, and label them.-Be aware of elevation/depth values on maps to know where to start drawing a contour.
-Remember v-rule from intro lab and why it exists.
-Know the significance of contours such as isobaths.-Practice contour plotting from Intro Lab and Lab 1

SEISMIC PROFILE
-Practice exercise on Lab 1 regarding sound wave travel through seawater and sediment/rock.

MID-OCEAN RIDGES, TRENCHES, PLATES-Know what these features are and how trenches and mid-ocean ridges form.
-Know where some of these features are located on a map (i.e. Mid-Atlantic Ridge, East Pacific Rise, Aleutian Trench, MarianaTrench, Pacific Plate, North American Plate, etc.)
-Know the 3 kinds of plate boundaries (convergent, divergent, and transform) and what makes them distinct from one another.
-Know the differencebetween an active and passive continental margin.
-Study maps from Lab 2.

SELECTED QUESTIONS FROM LAB 2/PART 1
-Study the questions from Lab 2/Part 1.
-I will select a handful of questions fromthere.

OCEAN PROFILE (CROSS SECTION)
-Know what the cross section of an ocean floor looks like (i.e. from North America to Africa).
-Know where the continental slopes, abyssal plains, andmid-Atlantic ridge is located with respect to an ocean floor profile.

CARBONATE COMPENSATION DEPTH (CCD)
-Know what is, where it is, the effect it has on Calcium Carbonate and why it has that effect on it.-Read description of CCD in Lab 3.

EMPEROR’S SEAMOUNT CHAIN (HAWAIIAN ISLANDS)
-Know what is and where it’s located.
-Look over exercise involving this feature in Lab 3.

OCEANSEDIMENTS/MATERIALS OF THE SEAFLOOR
-Know the different kinds of sediments (Terrigenous and Biogenous).
-Terrigenous (sand, silt, ash, dust, etc.)
-Know how terrigenous sediments are deposited into the ocean....
