Special Issue Information

Dear Colleagues,

As the global climate warms, significant changes occur in the Arctic and Southern Oceans. Loss of Arctic sea ice has occurred at least since 1979, while a small positive trend of sea ice cover appeared in the Southern Ocean until 2016, with a rapid declining trend afterwards. These changes in sea ice conditions can modulate the Earth’s radiation balance in Polar Regions, and further induce positive feedback processes. At the same time, internal decadal variability can also alter not only the sea ice cover in the Arctic and the Southern Oceans, but also the interactions between sea ice and ocean. This Special Issue aims to advance the current understanding of sea ice and ocean interaction and its influence on the regional and global climate under different timescales (interannual to decadal to multi-century). This will include but is not limited to how internal variability and anthropogenic forcing will modulate these interactions, how the changes in sea ice will modulate regional and global climate (such as the changes in atmospheric teleconnections, storm tracks, and jet streams), and whether the changes in sea ice can modulate the oceanic overturning circulation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Changes in Arctic sea ice since the middle of the last century are explored in this study. Both observations and climate model simulations show an overall sea ice expansion during 1953–1970 but a general sea ice decline afterward. Anthropogenic aerosols, nature forcing and atmospheric ozone changes are found to contribute to the sea ice expansion in the early period. Their effects are strong generally in late boreal summer. On the other hand, greenhouse gas warming has a dominant effect on diminishing Arctic sea ice cover during 1971–2005, especially in September. Internal climate variability also plays a role in the Arctic sea ice change during 1953–1970. However, it cannot solely explain the Arctic sea ice decline since the 1970s. Full article
