This expertly crafted course serves as an illuminating gateway into the Arctic, guided by an incredible feat of modern science: the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) research expedition, which saw scientists from around the world living in subzero conditions for a year aboard a ship intentionally frozen in Arctic sea ice. ### Course Overview Spanning multiple modules, the course relies on firsthand accounts and insights from leading Arctic scientists, making it both highly informative and engaging. It delves into the geography and geopolitics of the Arctic, atmospheric physics, oceanic processes, the vital role of sea ice, and the delicate ecosystems that thrive in such harsh conditions. Participants will immerse themselves in the challenges posed by climate change and the future of this fragile region. ### Syllabus Breakdown 1. **Course Introduction and Course Basics**: This initial module sets the stage by exploring the Arctic’s geography and the influences that shape its climate. It draws connections to historic expeditions, particularly the Fram expedition, laying a rich historical context for the MOSAiC mission. 2. **Atmosphere in the Arctic and Beyond**: This segment focuses on fundamental atmospheric physics, emphasizing the unique conditions of the Arctic. Here, students will learn about the energy balance of the Earth and the critical feedback mechanisms that influence climate patterns globally. The insights gained serve not only to understand the Arctic but to appreciate its connections to the world at large. 3. **The Arctic Ocean**: Participants are guided through an exploration of ocean processes, learning about how ocean circulation and stratification contribute to the Arctic climate. This module emphasizes the interconnectedness of the atmosphere, ocean, and sea ice, providing a comprehensive understanding of the region's dynamics. 4. **Sea Ice**: Understanding sea ice is paramount when studying the Arctic, and this module explores its formation, behaviors, and changes over time. Students will recognize how vital sea ice is to the climate system and how it responds to global warming. 5. **Arctic Biochemistry/Ecosystem**: The course then shifts focus to the ecosystems within the Arctic Ocean, detailing not just the megafauna, but also the critical roles played by microscopic organisms. This holistic view is essential in understanding nutrient cycles and overall biodiversity in the Arctic. 6. **Modeling Using Data from the Arctic**: One of the standout features of the course is its deep dive into climate modeling. This module teaches students the various modeling approaches that scientists use to predict future changes in the Arctic, thereby bridging the gap between field data and practical application. 7. **Challenges in the Arctic**: The concluding module synthesizes prior lessons, framing them within the broader challenges faced by the Arctic due to climate change. Participants will gain insights into the socio-political implications of these environmental changes, especially concerning indigenous communities and global shipping routes. ### Recommendation I wholeheartedly recommend "Frozen in the Ice: Exploring the Arctic" for anyone interested in environmental science, climatology, or natural history.

Syllabus

Course Introduction and Course Basics

In this module, we will take you on a tour of the Arctic and discuss topics like Arctic geography and geopolitics before introducing the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition. The module wraps up with a brief look back at the historic Fram expedition to the Arctic 150 years ago that inspired MOSAiC.

Atmosphere in the Arctic and Beyond

In this module, you will learn about the basic physics of the atmosphere with a specific focus on the Arctic. We will explore Earth’s energy budget and look at the structure of the atmosphere. Arctic clouds are an important player in the Arctic atmosphere and their role will be part of one video lecture. Finally, we will introduce you to the concept of feedbacks, systems responses that modulate the climate system and are the basis for connections to the lower latitudes. The module concludes with an overview of the goals of the MOSAiC Atmosphere research group and the data they are collecting.

The Arctic Ocean

In this module, we will take you on a tour of the Arctic Ocean. We will explore topics like ocean circulation and ocean stratification with a specific focus on processes that are happening in the Arctic. You will begin to draw connections to the coupling of the atmosphere, ocean, and sea ice and explore the chemistry of the ocean, nutrient distribution, and ocean productivity. The module concludes with an overview of the goals of the MOSAiC Ocean research group and the data they are collecting.

Sea Ice

In this module, you will learn about sea ice and the important role it plays in the Arctic climate system. We will discuss how sea ice forms, how sea ice interacts with sunlight, and how sea ice moves and behaves. We will also explore the change in sea ice thickness and distribution in the Arctic over time and in response to a changing climate. The module concludes with an overview of the goals of the MOSAiC Sea Ice research group and the data they are collecting.

Arctic Biochemistry/Ecosystem

In this module, you will learn about the ecosystems of the Arctic Ocean. We will briefly explore the megafauna, such as polar bears, but then focus the exploration on the importance of the microfauna, such as algae and plankton, and their connections to oceanic nutrient cycles and atmospheric phenomena. The module concludes with an overview of the goals of the MOSAiC Biogeochemistry and Ecosystems research group and the data they are collecting.

Modeling Using Data from the Arctic

In this module, you will dive into the world of climate modeling. You will learn from MOSAiC researchers what the different modeling approaches are, what we can learn from models, and how we can use field data from expeditions like MOSAiC to improve model forecasts. The module concludes with an overview of the goals of the MOSAiC Modeling research group and the data they are collecting.

Challenges in the Arctic

In this module, we will tie together what we learned in the previous modules and explore challenges that the new Arctic faces. We will discuss the impacts of a changing climate on the Arctic as a whole, discuss the research frontiers around connections between the Arctic and lower latitudes, and explore the potential impacts of climate change on shipping lanes, energy exploration and fishing as well as related environmental challenges such as plastics and oil spills. Finally, you will learn how climate change is already impacting and will continue to impact indigenous communities in the Arctic in different ways.
