课程名称：冰封北极：探索北极 课程概述：为何来自全球的数百名科学家会选择在北极海冰中让一艘船只被故意冰封整整一年，勇敢面对零下的温度和数月的极昼黑暗？虽然这听起来像一部虚构的冒险电影，但从2019年9月到2020年10月，MOSAiC（多学科漂流观测站用于研究北极气候）北极研究考察确实进行了一次这样的冒险。在本课程中，您将直接听到MOSAiC科学家和北极专家的见解，他们将讲述此次考察如何增强我们对北极和全球气候系统的理解，以及他们将在冰上、海下和空中收集哪种数据。课程开始时将介绍北极的地理、气候及探险历史，随后逐步讲解北极系统的基本组成部分：大气、海洋、海冰和生态系统。您还将学习如何利用MOSAiC收集的数据来改进气候模型的预测。最后，我们将探讨新北极所面临的挑战，包括气候变化对北极土著人民的不同影响。 课程大纲： 1. 课程介绍与基础知识：了解北极地理与地政学，介绍MOSAiC考察及历史上的弗拉姆探险。 2. 北极与其他地区的大气：学习大气基本物理，探讨北极气候反馈及MOSAiC大气研究组的目标与数据。 3. 北极海洋：探索海洋循环与分层，分析大气、海洋与海冰的耦合，以及海洋的化学、营养分布与生产力。 4. 海冰：了解海冰在北极气候系统中的重要性，讨论海冰的形成、光照互动及其变化。 5. 北极生物化学与生态系统：调查北极生态系统中微生物的作用，了解营养循环及气候变化对生态的影响。 6. 使用北极数据建模：学习气候建模及如何利用MOSAiC的实地数据改进预测模型。 7. 北极面临的挑战：结合前面模块讨论气候变化带来的影响，包括航运、能源开发和土著社区的变化。 通过本课程，学习者将对北极的复杂环境及其全球气候系统的关系有更深入的理解，并认识到应对气候变化的重要性。
Name:Course Introduction and Course Basics
Description: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.
Name:Atmosphere in the Arctic and Beyond
Description: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.
Name:The Arctic Ocean
Description: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.
Name:Sea Ice
Description: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.
Name:Arctic Biochemistry/Ecosystem
Description: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.
Name:Modeling Using Data from the Arctic
Description: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.
Name:Challenges in the Arctic
Description: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.
Why would hundreds of scientists from around the world intentionally freeze a ship in Arctic sea ice for an entire year, braving subzero temperatures and months of polar darkness? This may sound like a fictional adventure movie plot, but from September 2019 through October 2020, the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) Arctic research expedition did just this. In this course, you’ll hear directly from MOSAiC scientists and Arctic experts as they describe why this expedition is so key for increasing our understanding of the Arctic and global climate systems and what kinds of data they will be collecting during MOSAiC on the ice, under the sea, and in the air. The course kicks off with content around Arctic geography, climate, and exploration history, and then walks learners through the basics of the components of the Arctic system: atmosphere, ocean, sea ice and ecosystems. You will also learn how the data collected during MOSAiC will be used to improve climate model projections. Finally, we will wrap up the course by exploring challenges the new Arctic faces, including how indigenous peoples in the Arctic are being impacted in different ways by a changing Arctic environment.
