	A ship named Polarstern will spend a year drifting in Arctic ice near the North Pole. “The Multidisciplinary Drifting Observatory of the Study of Arctic Climate, or Mosaic as it is known, dwarfs previous expeditions of its kind… More than 600 scientists from 19 different nations will take part over the course of the year. Some are staying for a total of nine months. Living on a boat and floating ice camp more than 1,000km (621 miles) from the nearest solid land, they will work in vicious polar storms, temperatures as low as -45C and the long months of polar night over the winter.” bbc.com/future/story/20191004-largest-arctic-expedition-in-history-going-the-north-pole The BBC article is quite interesting and was written by a BBC journalist who will spend 6 weeks onboard. Its climate change assertions seemed halfway reasonable considering today’s political “climate.” I welcome this expedition to get first-hand data and knowledge of the ice parameters and other weather and environment facts. Note that recorded history for these measurements starts now. I found no political spin whatsoever in the Brietbart article below. breitbart.com/news/mosaic-expedition-selects-ice-floe-for-drift-through-arctic-ocean __________________ “I would rather have questions that can't be answered than answers that can't be questioned.” - Richard Feynman

	Two graduate students from The Ohio State University join the expedition. "As a mother, U.S. Coast Guard veteran, former social worker, scuba diver, drone pilot and scholar, Ohio State electrical and computer engineering (ECE) Ph.D. student Brandi Downs still isn’t done finding her path in life. Soon, she can add Arctic pioneer to that list." electroscience.osu.edu/news/2019/09/mosaic-ohio-state-students-join-historic-arctic-climate-science-expedition __________________ “I would rather have questions that can't be answered than answers that can't be questioned.” - Richard Feynman

	...."Since the late 1970s, the Arctic has lost an average of 20,800 square miles (53,900 square kilometers) of ice a year; the Antarctic has gained an average of 7,300 square miles (18,900 sq km). On Sept. 19 this year, for the first time ever since 1979, Antarctic sea ice extent exceeded 7.72 million square miles (20 million square kilometers), according to the National Snow and Ice Data Center. The ice extent stayed above this benchmark extent for several days. The average maximum extent between 1981 and 2010 was 7.23 million square miles (18.72 million square kilometers)."... 7.7 million square miles...The entire United States including Alaska is only 3.5 million square miles...That's a lot of ice! https://www.nasa.gov/content/goddard/antarctic-sea-ice-reaches-new-record-maximum __________________ All living things seek to control their own destiny....this is the purpose of life

	..."This project will use a Beryllium 7 (7-Be) method in a year-long expedition as part of the international Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition to assess the seasonal variability of aerosol deposition. This is the first modern opportunity for such a comprehensive study of the yearly depositional flux of trace elements (TEs) into the Arctic ocean/ice ecosystem. The combination of 7-Be and aerosol TE measurements has been shown to be an effective tool for estimating the atmospheric input of TEs in remote ocean regions where nearby land-based collection sites do not exist. The data generated in this work will be available to allow ground-truthing of models of aerosol deposition and atmospheric input of TEs. Atmospheric deposition is the dominant pathway by which anthropogenically-derived trace elements, especially mercury (Hg), enter the Arctic Ocean, and recent literature suggests that atmospheric deposition of biologically-essential trace elements such as iron (Fe) could play a major role in controlling biological productivity in the Arctic. Atmospheric transport and deposition of aerosols is an important delivery mechanism of natural and contaminant trace elements (TEs) to the Arctic. Existing data show that atmospheric deposition of contaminant elements like Hg, Pb, and Se may be a major input of these elements to the Arctic, with likely sources being anthropogenic - industrial or power plant emissions associated with fossil fuel combustion in Europe, Russia, and Asia. The atmospheric input of biologically-essential trace elements (e.g. Mn, Fe, Co, Ni, Cu, Zn) plays a key role in controlling biogeochemical processes in the ocean, and recent work suggests this might be true in the Arctic as well."... https://www.nsf.gov/awardsearch/showAward?AWD_ID=1753408 ..."The National Science Foundation (NSF) is a United States government agency that supports fundamental research and education .... ...With an annual budget of about US$7.8 billion (fiscal year 2018), the NSF funds approximately 24% of all federally supported basic research conducted by the United States' colleges and universities.^[3] .."... https://en.wikipedia.org/wiki/National_Science_Foundation So this has nothing to do with any global warming theories...it has to do with detecting trace elements...pollution __________________ All living things seek to control their own destiny....this is the purpose of life

	It looks like Polarstern is going in circles. Will it get any closer to the North Pole? __________________ “I would rather have questions that can't be answered than answers that can't be questioned.” - Richard Feynman
