Ryder Glacier Expedition 2019. The Ryder 2019 expedition with the Swedish icebreaker Oden targets the unexplored marine realm of Ryder Glacier, more specifically the Sherard Osborne Fjord and adjacent area of northern Nares Strait and the southern Lincoln Sea. It is a multidisciplinary expedition, spanning the fields of atmospheric chemistry and physics, archeology, biology, climatology, ecology, genomics, glaciology, oceanography, marine geology, geophysics and geochemistry. The overarching goal is to investigate the dynamics and development of the marine cryosphere and ocean conditions over time. Earth's marine cryosphere includes glaciers extending into the ocean, ice sheets with their base suppressed below sea level, sea ice, gas hydrates and subsea permafrost. Stockholm University

 

A Weather Station Above the Arctic Circle Hit 94.6 Degrees Fahrenheit. Amid the hottest month in recorded history, some records still stand out as absolutely jaw dropping. That's definitely true of a measurement made in the Arctic this July. According to data released in the National Oceanic and Atmospheric Administration's (NOAA) monthly climate analysis, a weather station in Sweden north of the Arctic Circle hit a stunning 94.6 Fahrenheit (34.8 degrees Celsius) last month. As an isolated data point, it would be shocking. But coupled with a host of other maladies, from no sea ice within 125 miles of Alaska to the unruly fires ravaging Siberia, it's an exclamation point on the climate crisis. Gizmodo

 

NOAA Confirms July 2019 as Hottest on Record; Unprecedented Ice Melt Observed in Arctic. In line with the observations from various climate scientists, a prominent scientific agency of the United States has confirmed that July 2019 was the hottest month on record. On Thursday, the US National Oceanic and Atmospheric Administration (NOAA) reported that the global temperature of July 2019 was 0.95°C higher than the 20th century average of 15.8°C. It is the maximum departure from average temperatures since global records began in 1880. Another troubling detail from the NOAA report is that the average Arctic sea ice has reached a historic low, indicating that the impacts of warming are already evident. Weather.com

 

NAU Study: Arctic Losing Carbon Faster Than Previously Thought. Scientists developed a new method to directly measure soil carbon in experimental plots. They found over five years of warming temperatures, the top layer of soil lost a quarter of its carbon. Ted Schuur, an author of the study in Nature Geoscience, says, "That's quite a bit, it's quite fast.... The Arctic is a large store of carbon and the potential for that to end up in the atmosphere makes this climate change problem all the more difficult." KNAU
