Top 20 Nations

The biggest players among nations are very evident in the lists of nations ranked by cites and papers. US researchers, with their studies of the Valdez spill and other US-based sources of petroleum contamination, have helped the nation's rankings immensely. Canada's extensive research places it in the #2 slot on both lists. Spain, whose researchers have spent so much time on the Prestige spill, also ranks in the top five on both lists.
The countries of origin of several other highly cited researchers and institutions also feature prominently on these lists; for example, Australia boasts Ian Snape, who ranks at #4 by total number of papers, and German researchers Tillman Lueders and Christian Griebler both have papers on the two-year list.
Some unique nations trickle into the cites per paper list. Some of these nations are doing oil contamination research in relation to their respective areas; for instance, Ireland has papers studying sediments in Cork Harbour, Scottish researchers are looking at contamination in the Firth of Forth and the Shetland Islands, Israel is on the list with papers about oil spills off the Mediterranean coast of their shores, Ecuador is concerned with the 2001 Jessica oil spill in the Galapagos Islands.

Overall General Information
Top 20 Scientists, Institutions, Journals, & Nations
Citation tables allow us to map compelling trends:
- Are there particular nations or institutions that might be expected to dominate research in the Topic area, and do the numbers bear out these expectations, or are there surprises?
- Who are the leading scientists and where are they located?
While these tables cannot offer a complete picture, the number of trends and anomalies that can be spotlighted or connected across categories is striking. The tables often lead to renewed perspectives to further explore and validate.
What are Special Topics?
