Characteristics and Trends of Ocean Remote Sensing Research from 1990 to 2020: A Bibliometric Network Analysis and Its Implications

Abstract

The ocean is of great significance in the climate system, global resources and strategic decision making. With the continuous improvement in remote sensing technology, ocean remote sensing research has increasingly become an important topic for resource development and environmental protection. This paper uses bibliometric analysis method and VOSviewer visual software to conduct analysis. The analysis focuses on the period from 1990 to 2020. The analysis results show that articles have been steadily increasing over the past two decades. Scholars and researchers form the United States, China and Europe (mainly Western European countries), as well as NASA, Chinese Academy of Sciences and NOAA have bigger influence in this field to some extent. Among them, the United States and NASA holds the core leading position. Moreover, global cooperation in this field presents certain characteristics of geographical distribution. This study also reveals journals that include the most publications and subject categories that are highly relevant to related fields. Cluster analysis shows that remote sensing, ocean color, MODIS (or Moderate Resolution Imaging Spectroradiometer), chlorophy, sea ice and climate change are main research hotspots. In addition, in the context of climate warming, researchers have improved monitoring technology for remote sensing to warn and protect ocean ecosystems in hotspots (the Arctic and Antarctica). The valuable results obtained from this study will help academic professionals keep informed of the latest developments and identify future research directions in the field related to ocean remote sensing.

A Bibliometric Analysis and Overall Review of the New Technology and Development of Unmanned Surface Vessels

“…To offer more comprehensive insights into the advancement of cutting-edge technology in respect of USVs, this investigation conducted a systematic retrieval of scholarly articles focusing on USVs from the Web of Science (WoS) Core Collection database. Compared with other databases, WoS core database is more widely used and authoritative, and relevant published high-quality articles [19][20][21][22][23] have adopted WoS as their supporting database. Through the application of bibliographic analysis, this research delineated the prominent areas of investigation and the methodologies employed in the exploration of subjects related to USVs.…”

Exploring collaborative patterns in marine remote sensing literature through the fusion of complex networks and GIS

“…Xu et al utilized bibliometric approaches to assess the application of remote sensing in rice monitoring between 1980 and 2021 [8] . Wang et al employed bibliometric methods to investigate the global trends in marine remote sensing research spanning from 1990 to 2020 [9] . These examples highlight the widespread use of bibliometric methods in the field of remote sensing.…”

Electromobility: Logistics and Business Ecosystem Perspectives Review

“…There has been a growing emphasis on this aspect in recent years, suggesting that the success of electromobility is closely linked with the vibrancy of its business ecosystem [53,54]. However, like any significant transition, this evolution comes with its challenges [55,56]. Companies are compelled to adapt to innovative solutions [57,58], influenced not only by technological advances but also by social, legal, and environmental factors [59,60].…”
