Course Description

Overview

Explore the diverse marine provinces of Earth's oceans in this comprehensive 46-minute lecture. Dive into the methods of measuring bathymetry, including echo sounding and modern techniques like sea floor mapping from space. Examine various bathymetric maps and seismic reflection profiles to understand ocean topography. Learn about major ocean regions, focusing on the North Atlantic, and distinguish between passive and active continental margins. Investigate features of the ocean floor such as continental shelves, slopes, submarine canyons, and abyssal plains. Discover the formation of turbidity currents and their impact on underwater landscapes. Study volcanic structures like seamounts, tablemounts, and the Pacific Ring of Fire. Analyze the characteristics of mid-ocean ridges, including hydrothermal vents, fracture zones, and transform faults. Conclude with an exploration of oceanic islands and witness the emergence of new volcanic islands.
