Soft Question: How Best to Thoroughly Exhaust the Literature I am trying to make sure I have done my due diligence in researching the literature when it comes to a particular topic in oceanography and/or atmospheric science.  My specialization is in a different subject altogether, where we have one website in particular that has a collection of abstracts and titles for nearly all papers that have ever been published (pre- and post-internet era) in this particular area.  Those of us in the field can search the one website for certain keywords, and once you have done this with some variations on said keywords and then combed the relevant citing/cited literature, it's pretty safe to say you've done your due diligence to comb the literature.  Is there a similar website for the areas of oceanography and/or atmospheric science or does one usually use Google Scholar?  Any help would be much appreciated, thanks!
I would suggest combing Google Scholar with the following methods:


Search keywords just as you've mentioned.   
When you hit on a semi-relevant paper, check the citations for relevant information.
Additionally check the collected works of the authors of said papers.  
Search specifically for review papers or graduate-level textbooks for context on a subject and more citations.  


The perk of interdisciplinary Earth Science is that everything connects.  The downside of interdisciplinary Earth Science is that information is dispersed.  Good luck.
