1. Introduction

The Arctic region is a keystone to understand the present status of the currently ongoing Earth system, such as the climate change, together with to predict future images of our planet as viewed from the northern high latitude. The Arctic region, composed by the ice-covered Arctic Ocean in its center and surrounding fragmentation of major continents, has been rapidly investigated during the last half century by all kind of scientific studies including bioscience, physical sciences, geosciences, oceanography, and environmental studies, together with the technological domain. Major location names in the Arctic region are illustrated in Figure 1.

Red solid circle represents the “Arctic circle” (66.6°N). Abbreviations of representative local names are as follows: SV, Svalbard; MR, Mendeleev Ridge; HB, Hudson Bay; red solid triangles are the permanent stations; KMS, Kamenskoye Station; NAS, Ny-Alesund Station; ICE-S (south).

2. Scope of the book

This book covers the topics on recent development of all kinds of scientific researches in and around the Arctic region, with a viewpoint to monitor the current variations in the extreme environment, affected by remarkable changes in temperature and sea-ice extent, mass loss of ice-sheet and glaciers, and variations in marine and terrestrial ecosystem including human activities. Multidisciplinary and interdisciplinary approaches are beneficial in polar researches, focusing on the interrelated perspectives which will be needed to understand and quantify their connections with the prediction of future climate system change.

In this concern, particularly the cryosphere system is likely to be influenced by temporal–spatial variations in surface environmental conditions in the Arctic, and continuous researches of their variability provide direct evidence of climate change. For instance, large glacial-involved earthquakes are the most prominent phenomena found particularly around Greenland [1, 2, 3]; the new innovative studies conducted by glaciological and geophysical investigations are strikingly encouraged by long-term monitoring observations under extreme conditions in the area.

The most exciting initiative in the Arctic region was the International Polar Year (IPY) in 2007–2008, which had been conducted at the 50th anniversary of the International Geophysical Year (IGY 1957–1958). The IPY was a big international program composed of multidisciplinary science branches: upper atmosphere, meteorology, glaciology, geosciences, oceanography, and biosciences conducted by a significant number of polar scientists involved [4]. The initiative significantly enhanced the exchange of ideas across nations and scientific disciplines to unveil the status and changes of planet Earth. This kind of interdisciplinary approach helps us understand and address grand challenges such as rapid environmental change and its impact on human society.

The recent seismological research achievements in the polar region, for instance, are compiled in the special issue on “Polar Science” [5]. By taking into account the above concerns, however, this book partially aims to collect many discipline achievements by a significant number of involved projects at the IPY and post era, primarily focusing on surface environmental variations associated with climate change such as global warming.

It is also mentioned that, moreover, the contents in this book intend to appeal not only to the polar scientists but also to all general public who are interested in the present status of the Arctic region. It is hopeful that this book could provide remarkable knowledge and new understanding regarding current environmental variations and the past Earth’s history within the global dynamics. The book could surely attain fruitful information on an advance of frontier researches in the Arctic region which are currently suffering significant effects by climate change within the global system.
