NOAA recently released the 2019 Arctic Report Card at the American Geophysical Union Fall Meeting providing updates on the ongoing impact of changing conditions in the Arctic on the environment and communities, especially from continued warming and record sea ice loss. This work brings together 81 scientists from 12 nations to provide the latest in peer-reviewed, actionable environmental information on the current state of the Arctic environmental system relative to historical records.
The average annual land surface air temperature north of 60° N for October 2018-August 2019 was the second warmest since 1900. The warming air temperatures are driving changes in the Arctic environment that affect ecosystems and communities on a regional and global scale.
In the marine environment, August mean sea surface temperatures in 2019 were 1-7°C warmer than the 1982-2010 August mean in the Beaufort and Chukchi Seas, the Laptev Sea, and Baffin Bay. Arctic sea ice extent at the end of summer 2019 was tied with 2007 and 2016 as the second lowest since satellite observations began in 1979. The thickness of the sea ice has also decreased, resulting in an ice cover that is more vulnerable to warming air and ocean temperatures... more

OceanObs’19 was held in Honolulu, Hawaii, in September 2019. The conference presented a unique forum to share new ideas and concepts in marine data management and to emphasize the opportunities presented by a rapidly changing technology landscape. The OceanObs’19 conference was designed to bring: “… people from all over the planet together to communicate the decadal progress of ocean observing networks and to chart innovative solutions to society’s growing needs for ocean information in the... more
