EAPS 105 Exam 1 Study Guide: Mastering Introductory Oceanography

Are you feeling overwhelmed preparing for your first EAPS 105 exam? Don't worry, you're not alone! Introductory Oceanography can cover a vast range of topics, from the physics of ocean waves to the intricate biology of marine life. This comprehensive study guide will break down the key concepts typically covered in Exam 1, providing you with a structured approach to mastering the material. We'll focus on effective study strategies, highlight crucial topics, and offer tips for maximizing your performance.

Understanding the Scope of Exam 1

Exam 1 in EAPS 105 usually focuses on the foundational aspects of oceanography. The specific topics may vary slightly depending on your instructor, but generally, you can expect questions covering:

• Introduction to Oceanography: This section sets the stage, defining oceanography as a discipline and exploring its interdisciplinary nature. Expect questions on the history of oceanographic exploration, the significance of the ocean's role in Earth's systems, and the various sub-disciplines within oceanography (e.g., physical, chemical, biological, geological).

• Earth's Structure and Plate Tectonics: A strong understanding of plate tectonics is vital. Be prepared to explain the theory of plate tectonics, identify different plate boundaries (convergent, divergent, transform), understand their associated features (volcanoes, earthquakes, mid-ocean ridges, trenches), and relate them to the formation and evolution of ocean basins. Remember to connect this to the distribution of continents and ocean features.

• Ocean Floor Topography: This section delves into the physical characteristics of the ocean floor. Master the terminology associated with different underwater features: continental shelf, slope, rise, abyssal plain, mid-ocean ridges, hydrothermal vents, seamounts, trenches. Understanding the processes that form these features (e.g., sedimentation, volcanism, plate tectonics) is crucial. Be prepared to interpret bathymetric maps and understand their significance.

• Physical Properties of Seawater: You'll need a strong grasp of the physical properties of seawater, including salinity, temperature, density, and pressure. Understand how these properties vary with depth and location, and how they influence ocean currents and water mixing. The concept of thermohaline circulation is usually emphasized.

• Ocean Waves: This section typically covers the generation, propagation, and characteristics of ocean waves. You'll need to understand wave terminology (wavelength, frequency, amplitude, wave height, period), different types of waves (wind waves, tsunamis, tides), and the factors that influence wave formation and behavior (wind speed, fetch, water depth). Be able to distinguish between deep-water and shallow-water waves.

• Ocean Currents: Understand the driving forces behind ocean currents (wind, density differences, Coriolis effect, tides), and be able to describe the major ocean currents (e.g., Gulf Stream, Kuroshio Current, California Current) and their impact on climate and marine ecosystems. The role of the Coriolis effect in deflecting currents is particularly important.

• Introduction to Marine Life (often covered in Exam 1 or 2): This might include a basic overview of marine ecosystems, the different zones of the ocean (intertidal, neritic, oceanic, benthic, pelagic), and the major groups of marine organisms (plankton, nekton, benthos). Focus on understanding the basic adaptations of marine organisms to their environment.

Effective Study Strategies for EAPS 105

Success in EAPS 105 requires a structured approach to studying. Here's a breakdown of effective strategies:

1. Active Recall and Spaced Repetition:

Instead of passively rereading your notes, actively test yourself. Use flashcards, practice questions, or teach the concepts to someone else. This strengthens memory and identifies areas needing more attention. Spaced repetition – reviewing material at increasing intervals – enhances long-term retention.

2. Concept Mapping and Mind Mapping:

Create visual representations of the relationships between different concepts. This helps to synthesize information and identify key connections, making complex ideas more manageable.

3. Problem-Solving Practice:

Work through practice problems and past exams (if available). This allows you to apply your knowledge and identify areas where you struggle. Don’t just look for the answers; focus on understanding the process of solving the problem.

4. Utilize Your Textbook and Lecture Notes:

Your textbook is your most valuable resource. Read actively, take notes, and highlight key concepts. Supplement this with your lecture notes, paying close attention to what your instructor emphasizes.

5. Form Study Groups:

Collaborating with classmates can significantly enhance your understanding. Explaining concepts to others helps solidify your own knowledge, and you can learn from different perspectives.

6. Seek Clarification:

Don't hesitate to ask your instructor or TA for clarification on concepts you don't understand. Attend office hours or utilize online discussion forums.

Deep Dive into Key Concepts: A Detailed Breakdown

Let's delve deeper into some of the most critical topics likely to appear on your Exam 1:

Plate Tectonics and its Oceanic Impact:

• Seafloor Spreading: Understand the process by which new oceanic crust is formed at mid-ocean ridges.
• Subduction Zones: Grasp the process of oceanic crust being pulled beneath continental crust, leading to volcanic activity and earthquakes.
• Transform Faults: Learn how these boundaries cause horizontal movement and frequent earthquakes.
• Magnetic Anomalies: Understand how these patterns on the seafloor provide evidence for seafloor spreading.
• Ocean Basin Formation: Connect plate tectonics to the creation and evolution of different ocean basins.

Ocean Floor Topography:

• Continental Margins: Understand the differences between passive and active continental margins.
• Abyssal Plains: Learn about their formation and characteristics as vast, flat areas of the deep ocean floor.
• Seamounts and Guyots: Understand their volcanic origins and the processes that shape them.
• Hydrothermal Vents: Learn about their unique ecosystems and the chemosynthetic organisms that thrive there.

Physical Properties of Seawater:

• Salinity: Understand its variations and the factors that influence it (e.g., evaporation, precipitation, river runoff).
• Temperature: Learn about its vertical and horizontal variations and its influence on density.
• Density: Understand how temperature and salinity affect density and its role in ocean circulation.
• Pressure: Learn how pressure increases with depth and its impact on marine organisms.
• Thermohaline Circulation: Understand the role of temperature and salinity in driving deep ocean currents.

Ocean Waves:

• Wave Formation: Understand the process by which wind generates waves.
• Wave Characteristics: Be able to define and calculate wavelength, frequency, amplitude, wave height, and period.
