Marine observation and detection technology is an important component of marine science and technol-ogy and plays an essential role in warning against marine disasters,developing marine resources and space,pro-tecting the marine environment,safeguarding marine rights and interests,and strengthening national defense con-struction.Research on marine observation and detection instruments is important for developing marine observation and detection technology.This study clarifies the current research status and hotspots of instrument technology for marine observation and detection by first retrieving the related English articles published between 1998 and 2022 from the Web of Science and then statistically analyzing them in terms of the quantity of publications,disciplines involved,authors,institutions,keywords,and other aspects using bibliometric and visual analyses.The current re-search status and hotspots are summarized here.First,research on instrument technology for marine observation and detection has shown a rapid growth trend in the past decade.In China,research in this technological field began relatively late but rapidly developed.After 2018,it has steadily ranked first in the world in terms of the publication quantity of articles from Chinese researchers in this field.Three of the top ten authors of highly cited papers are Chinese scholars,showing that some Chinese researchers have a considerably influence in this field.However,in terms of publication quantity,most of the top 10 institutions are American institutions,and no scholar is Chinese by nationality among the top 10 high-yield authors.Hence,the influence and competitiveness of Chinese researchers in this field must be further improved.Second,the results of the word cloud clustering analysis show that the global research hotspots in this field are focused on unmanned aerial vehicles,magnetometers,microwave radiometers,sea surface temperature,and water color.Note that the association words of the ocean sensor are mostly keywords from the clustering analysis,indicating that the ocean sensor is a key research focus in this field.From the perspective of research focus evolution,despite starting late,China plays a certain leading role in the transfer of research hotspots on instrument technology for marine observation and detection due to its strong research tracking ability and rapid transfer of theme evolution.
