Diatoms are the most important producers of plant biomass in the ocean and help to transport carbon dioxide (CO2) from the atmosphere into the deep ocean and thus regulate our climate. Because diatoms rely on silica rather than calcium carbonate to build their shells, they were previously thought to benefit from ocean acidification -- a chemical change in seawater triggered by the increasing uptake of CO2 that makes calcification more difficult. Scientists now show that diatoms, which are a type of plankton, are also affected. Analyses of data from field experiments and model simulations suggest that ocean acidification could drastically reduce diatom populations.

Present-day wolverines, which emerged during the ice age, have been declining globally despite their many adaptions to live in challenging, rugged environments. These large land-dwelling weasels evolved to scramble up trees and climb steep, snowy mountains. Wolverines' snowshoe-like paws, heavy frost-resistant fur and powerful muscles let them thrive in some of the coldest places on Earth. Their sharp claws and strong jaws allow them to feast on carcasses and hunt species of all sizes from ground squirrels to elk.

Many adverse space weather impacts arise when bursts of magnetic energy are released from the tail of Earth’s magnetosphere. These bursts, known as substorms, occur when energy from the solar wind enters the dayside magnetosphere and is transported to the tail (the growth phase of a substorm), where it gradually builds up until abruptly released (many such releases may occur during the course of an intense geomagnetic storm). The energy transported to the tail produces a magnetic signature in the polar regions of the Earth.

The new Arctic Research Plan 2022-2026 articulates the need for continued work towards ethically open data and research practices. But what does “open science” mean for Arctic research funders? And how can you get funding to support it? IARPC hosts this program officer chat with the National Science Foundation and NASA. Program officers will talk about what open science means in their programs, and how NASA and NSF provide funding and support to advance open polar and cryospheric science. After short presentations, there will be Q&A with the panel.

This event is hosted by The Arctic Institute (TAI). This event will include topics on: cultural security, economic security, energy security, environmental security, food security, health security, military security, and political security.

The events during the week of August 1st, 2022, will include Enhancing Arctic Science and Engineering Workshop along with Regional Development Tours and forums on the Arctic science to plan for the next 25 years of Arctic research. Participants will include scientists and engineers, Indigenous leaders, Arctic community members, policymakers, government organizations and businesses to celebrate past research success, take stock of current challenges and opportunities and plan for the next generation of collaboration and knowledge co-production that will keep Utqiagvik and Indigenous knowledge at the forefront of Arctic science and contribute to a safe and sustainable future for

the Arctic.

The Forum is organized in cooperation with Naalakkersuisut - The Government of Greenland. The Focus of the 2022 Greenland Forum will be on climate and prosperity; and, geopolitics and progress.

The Arctic Circle Assembly is an open democratic platform with participation from governments, organizations, corporations, universities, think tanks, environmental associations, indigenous communities, concerned citizens, and others. It is nonprofit and nonpartisan.
