Welcome Home Polarstern!
On Monday, October 12th we will welcome the Polarstern back to port after spending a year in the Arctic for the 2019-2020 MOSAiC expedition. The ship will return to Bremerhaven, a port city on Germany's North Sea coast. The ship will have traveled over 15,000 km (>9300 miles) over the course of the past year, much of that time spent passively drifting with the Arctic Ocean currents frozen in sea ice.
In the best of times and with perfect conditions, this expedition would have been a challenging and logistically complex achievement. But this past year brought many additional and some completely unexpected challenges for the expedition which it was still able to successfully continue through, including a global pandemic and unprecedented warming in the Arctic leading to the second lowest sea ice minimum on record. The data collected during this crucial field expedition by scientists who endured harsh and unforgiving working conditions and months away from their loved ones will improve our understanding of the Arctic climate system and our ability to more accurately represent the Arctic in global climate models.
In addition to the dedicated scientists, we also want to acknowledge all of the expedition crew members, logistics experts, polar bear guards, filmmakers, journalists, photographers, and educators who have been a part of this yearlong endeavor. MOSAiC was truly an international collaborative effort, and every person involved was an important piece of the puzzle. And thanks to all of the educators, students, and folks at home who have been following us over the past year!
How to Watch the Polarstern's Arrival Home
You can watch a livestream of the Polarstern's return to port and other events happening to celebrate the end of MOSAiC expedition fieldwork. Check out all of the events being hosted and broadcasted by the Alfred Wegener Institute here. Note to folks not in Europe: Many of the livestreams will be happening between 2-7 AM Eastern Time, so it might not be plausible for you to tune into the livestream, but you can still check out the recorded return during whatever time is convenient for you!
Recognizing Indigenous Peoples
Monday, October 12th is Indigenous Peoples Day in the United States. It is a day to celebrate and honor Native American peoples, their histories, and their cultures. Of the nearly 4 million people live in the Arctic region, roughly 10% are Indigenous. Indigenous peoples have been practicing their traditional ways of life in the Arctic for thousands of years, but as the Arctic climate and environment is changing, these ways of life and the livelihoods of Indigenous peoples are being threatened. Thawing permafrost, decreasing sea ice, coastal erosion, and invasive species are all phenomena contributing to this threat.
On this Indigenous Peoples Day, we invite you to learn more about the Indigenous peoples of the Arctic, their intimate knowledge of and relationship with the region, and how their ways of life are being threatened by climatic and environmental change.

Follow MOSAiC with Reach the World through November!
You can continue to connect virtually with MOSAiC team members through November with our friends at Reach the World and Exploring by the Seat of Your Pants!
Did you miss the live video call with Laura Schmidt on Monday October 5th? Not to worry! You can watch a recording of Laura's call on the RTW MOSAiC program page or on the Exploring by the Seat of Your Pants YouTube channel.
Hot off the Press: Take a Virtual Reality Tour of the MOSAiC Expedition!
Our friends at the Byrd Polar and Climate Research Center at the Ohio State University have created an incredible virtual reality tour of the MOSAiC expedition. In this 'choose your own adventure' tour, you are able to explore the MOSAiC Ice Camp like never before and get a front row seat to the unprecedented work conducted by MOSAiC scientists!

A Note to MOSAiC Monday Followers
The return of the Polarstern signifies the end of the field portion of MOSAiC, but not the end of the research efforts. In fact, much of the really crucial work--the data analysis--is just beginning. Thus, our work isn't finished either. We'll continue to bring you new and exciting educational resources related to the MOSAiC expedition, including more ArcGIS StoryMaps and activities like Data Nuggets that allow students to explore real MOSAiC expedition data in the classroom. However, starting in November, we'll be switching from MOSAiC Monday to MOSAiC Monthly, sharing new resources and news with you every month instead of every week. There's nothing that you need to do except stay subscribed to the MM newsletter!
Is there something you'd like to see in MOSAiC Monthly? Let us know! Email us at email@example.com
Coming up: Science@Home and CLEAN Elementary Opportunities
Tune in weekly from now through December for the CIRES/NOAA Science at Home Webinar Series!
Join us every Tuesday at 1:00 pm MT from now through December for the CIRES/NOAA Science at Home webinar series! Each webinar features a 10-15 minute presentation by a scientist about how they got into science and what they do as a scientist, followed by 10-15 minutes of live Q&A.
October 13th – Dr. Matt Druckenmiller will present on: Exchange for Local Observations and Knowledge of the Arctic (ELOKA)
October 20th – Dr. Aleya Kaushik will present on: The Arctic Carbon Cycle
Looking for activities for your students to do from home? Have your K-5th grade students join CLEAN (Climate Literacy & Energy Awareness Network) on October 21st at 1pm MT for a virtual live lesson about melting ice, and its relation to climate. Students will get to experiment with ice during this fun, hands-on lesson, which only requires ice, salt & pepper, as well as dark and light-colored plates if students have them! (Clear cups, a ruler, thermometer, and stopwatch are also useful but not necessary). This lesson also connects with several of the Science@Home talks by CIRES/NOAA scientists that would be appropriate for upper elementary and older students (see above).
MOSAiC Weekly Tracking - Final Week!
Each week we will provide you with the latitude and longitude coordinates of the Polarstern so that you can track its journey across the Arctic.
