Every third month Science direct lists the twentyfive hottest articles within a specific field of research. The list is based on number of downloads for each article. Unfortunately there is a lagtime between the download count over a three month period and the time the list is published, which means that the Hot topics list today (21/1 2012) still displays the most downloaded papers during July to September 2011. However, the list is still a good indicator if one wants to find out what’s hot in geosciences.
Based on the Science Direct list for July to September have compiled the three hottest topics within Earth and Planetary sciences, and these are:
- Ecology/Palaeoecology/Evolution 10/25
- Environment and pollution 7/25
- Water treatment/resources 4/25
Since the last published list the research focus has changed somewhat. Although the most downloaded papers are still within Ecology/Palaeoecology several of those papers also deal with evolution.
Number two on the last list, Climate/Global change research, appears to have lost some ground to Environment and Pollution, perhaps indicating a societal trend that we have to clean up in our own backyards before accomplishing global changes.
In third place there is a lot of focus on our freshwater resources and their quality, something that is of vital importance in many areas around the world.
Important issues to consider for us all!
