3.1. Scopus Database and Results of Assessment
As a result of our Scopus search, we received 150 documents from 1965 to 2020, where the most productive years were 2004 (12 articles), 2007 (eight articles), 2012, 2005, and 2003 (six articles each) (Figure 2
). Meanwhile, Mauk J.L. wrote 13 articles about Coromandel Peninsula, followed by Nelson C.S. and Moore P.R. (eight articles each), then Bryan K.R. (seven), Simpson M.P., Rowan D., and Christie A.B. (six each), with this list being only those scientists who made the highest value on the study of this area. Hence, this territory seems to have become visible to the global science community through globally relevant research outputs since 1965, which is a reasonably long time. However, its database has only 150 documents from the different fields of importance through the region, while similar random tests for other geologically and geographically similar locations gave higher results. For example, the Carpathian Mountains in Eastern Europe (Miocene–Pliocene subduction-related bimodal volcanism [andesitic to dacitic/rhyolitic], greywacke basement, and thick flysch successions but colder, temperate climate, and more alpine morphology) consistently yielded research outputs nearly two orders larger than the number of research outputs for our studied area (The Coromandel Peninsula) [38
For the studied areas, we directed our attention towards the authors’ keywords mentioned in information about every manuscript. According to the result from authors’ keywords (total number of 702 words or phrases) (Table 1
), “Geochemistry” was the most popular and was mentioned five times, (except “New Zealand”, 34; “Coromandel Peninsula”, 14; and “Coromandel”, seven times), then “Taxonomy”, “Northland”, “New Zealand Flora”, “Miocene”, “Ignimbrite”, and “Great Barrier Island” were mentioned four times each. Meanwhile, index keywords compounded by Scopus (1985 words or phrases) contain “North Island” (59 keywords), Waikato (47), and Australasia (33) were the highest number of words (except “New Zealand” (107) and “Coromandel Peninsula” (54), which have not been included as they are search words), which are connected mostly to the location of the place without any connection to a specific scientific field. Then, “Asystasia gangetica” was mentioned for 20 articles, “Hydrothermal alteration” (11), and “Gold deposits” and “Forestry” (10 times each). More precise information is outlined in the table below, where author keywords are presented together with Index 1.
From Microsoft Office Excel calculations (Table 2
), author keywords and index keywords were justified as the most relevant by researchers’ topics around the Coromandel Peninsula region; however, the table contains the number of words, which can be used in any kind of research, such as names of locations. Hence, we used a color code for the table (Table 2
) to highlight different fields of studies such as geology (red color), biology (green color), locations (light-green color), and periods (gray color).
Except for keywords, the Scopus database contained statistics about articles connected to different fields of research (Table 3
). Hence, 71 articles were written about “Earth and Planetary Sciences”, then 54 for “Agriculture and Biological Sciences”, and 43 for “Environmental science”. After this, the number of articles dropped to 15 manuscripts in “Social Science” and eight and seven in “Arts and Humanities” and “Multidisciplinary”, respectively, while other areas of studying were low in the Coromandel Peninsula.
In conclusion, the general information shown in Table 1
demonstrates that the Scopus database contained 150 articles about Coromandel Peninsula, and keywords (Table 2
) show most of them were about geology and more specifically about volcanic activities, justified by keywords such as “Obsidian”, “Volcanism”, “Tephra”, “Geochemistry”, “Epithermal deposits” and others. Meanwhile, biological spheres were also studied in this region and words like “Vegetation”, “Radiata Pine”, “Asystasia gangetica”, “New Zealand flora” and “Forestry” showed the interest in the Coromandel Flora. Additionally, words like “Spongiidae”, “Spongia”, “Invertebrate”, and “Porifera” demonstrated the fauna part of the study of marine life, especially sponges, “Succineidae”, and “Succinea archeyi” snails. Other keywords such as “Taxonomy”, “Structure”, and periods “Miocene” and “Pleistocene” were not related to any kind of specialization as they can be used in multiple fields, which have not been checked as they have no significant influence. The same trends for science priorities can be seen in areas of studying databases shown in Table 3
, where geological, biological, and environmental research were dominant in comparison to other fields. Additionally, the number of research areas in the table of studying areas was higher than the number of documents, 180 and 150, respectively. Hence, some documents were included in two or more areas. This pattern, mostly visible between environmental science and agriculture and biological science, 21 documents, showed a strong connection in these areas. It was followed by collaboration between Earth and Planetary Sciences and Environmental science—12 documents. Meanwhile, seven documents mentioned multidisciplinary areas of studying related to geological, biological, and environmental subjects and related collaboration. In the next sections we demonstrate how information taken from other sources can further refine the overall picture based only on the Scopus data.
3.2. Web of Science Database and Results of Assessment
The Web of Science search through topics with the words “Coromandel Peninsula” and “New Zealand” in the results found 180 documents in the period from 1946 to 2020 (Figure 3
). From the figure, the most productive years were 2003–2004, 2007, and 2020 as they included publication of eight and more manuscripts about Coromandel Peninsula. According to the authors’ influences, Mauk J.L. was mentioned in eight articles, then Simpson M.P. (seven documents), Christie A.B (six), Quinn J.M. (five), and Bryan K.R. (four).
As previously mentioned, WoS does not provide a dedicated database about keywords like Scopus does, but it does include information about science fields (Table 4
), where “Environmental Science Ecology” shows the highest number of articles (96), followed by “Zoology” (68), “Life Sciences Biomedicine Other Topics” (44), then “Biodiversity Conservation” and “Geology” (39 each).
In conclusion, we can state that analysis of our searches within WoS and Scopus yielded similar results for number of peaks of annual productivity for articles about the Coromandel Peninsula (Figure 2
and Figure 3
). For influence of authors, we saw that most of the manuscripts in both databases contained the same names, such as Mauk J.L., Simpson M.P., Christie A.B., Bryan K.R., and others. However, keyword analysis of Scopus results (Table 2
) showed that the most significant field of research in the Coromandel was geology (specifically, volcanology and hydrothermal deposits), then flora and botany, and fauna presented by studies about marine sponges and snails, as shown in research areas outlined in Table 3
. The WoS database about areas of research (Table 4
) showed that topics like biology, biodiversity, environmental conservation, and zoology showed a higher ranking than geology, which did still remain at a relatively high position.
3.3. JSTOR Database and Results of Assessment
Results for JSTOR showed 784 documents and three pictures, with half of them showing no connection to Coromandel Peninsula and New Zealand at all. Therefore, we chose to concentrate specifically on the mentioned phrases. Using this option, our search showed 357 documents and two pictures (Table 1
), which were published in the period from 1883 to 2019. From the period (Figure 4
), 1980 was the most productive year on the topic connected to the Coromandel Peninsula (18 documents), then the next peak was in 1998 with 11 articles. For influence of authors, Hayward B.W. wrote 10 articles, then Morley M.S. (nine articles), Davidson J. (eight), Thrush S.F. (seven), and Healy T.R., Golson J., Furey L., Eagle M.K., and Bryan K.R. were mentioned in six different manuscripts.
The JSTOR database is like WoS, in that it does not provide information about keywords, but it does contain a table, with different areas of research (Table 5
). According to our search, 183 manuscripts were written on the subject of “Ecology and Evolutionary Biology”, then 77 on “Biological Science”, and 75 on Asian Studies. Continuing on, 58 and 48 articles were related to “Anthropology” and “Archeology”, respectively. Meanwhile, on geological studies, only five were written for each “Geology” and “Paleontology”. Other areas of study were shown to have much less impact on the Coromandel Peninsula.
In conclusion, the JSTOR database showed different information compared to Scopus and WoS. Firstly, it provided two times more results than the other two studied databases. Additionally, within JSTOR searches, new authors tended to appear such as “Hayward B.W.”, who also had the highest number of articles on the topic of “Coromandel Peninsula” according to the JSTOR database. This was despite his research outputs being barely noticed in Scopus and WoS. This might be a result of any of the following: The science media his publications appear in have not been captured properly; his publications date back to a time not captured by other databases; or research outputs were not specifically associated with Coromandel Peninsula at a level that would have been captured by Scopus or WoS.
On the other hand, JSTOR’s fields of study (Table 5
) provided similar outcomes to those found by searching through WoS (Table 4
) in environmental and biological studies. In both cases, the highest amount of research occurred in geology in WoS, and completely opposite results were found in JSTOR compared to Scopus keywords (Table 2
) and areas of research (Table 3
) results, where most of them were around geological areas of science.
