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.

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.

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.

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.

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.

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.
