Database Searching and the Power of Limiters


Marine Biology

Database Searching and the Power of Limiters (updated R. Musco 4-2017)

Information literacy topics:

  • Determining best sources

  • Searching strategies for information

  • Evaluating sources

  • Using technology tools



1: Find the activities for this class, at:

Amity website→High SchoolAHS Library Information Center

(tab) Find Online Stuff→By Subject→Science

(tab) Class Projects →CournoyerDatabase Searching and the Power of Limiters


2. Objective: What do we want to accomplish today?

To perform an efficient search for peer-reviewed academic journal articles, and/or magazine and newspaper articles on a given topic, using limiters in a college-level database (EBSCO’s Academic Search Complete)


3. Choosing the best resource:

Some databases from our library webpage with science articles:



Environmental Topics, All Formats




Mainfile and MasterFile

All Topics, All Formats






Science in Context

Science Only, for School




Academic Search Complete

All Topics, All Formats, 9000 Academic Journals



Academic Search COMPLETE: From the publisher EBSCO, Academic Search Complete has the largest number of peer-reviewed academic journals (9000) of all our databases, through a wide range of academic disciplines, from the behavioral and technical sciences, through education, theatre, and many more. It includes some popular magazines as well as scholarly journals.


4. Searching strategy: Search Terms

ESBCO:  Academic Search COMPLETE:

Main points:

  • Take note of your surroundings:  Look at main menus, search options, etc..

  • Search box:

    • Always give yourself more options with an “Advanced Search”.

    • Consider what you are searching for: Title? Author? Subject? Word in text?

    • Start simple.  You can always add more words to narrow down.

    • Too many results and not really relevant? Add more words to narrow down.

    • Too few results? Broaden your search with fewer words.

    • Use more advanced techniques:

      • Try with synonyms or related words (turtle, turtles, excluder, excluding, exclud*. etc.)

      • Use commands (“operators”) to narrow down: AND (to get both terms), OR (for one OR the other), NOT (to filter out the word), apostrophes around several words like “turtle excluder” or “fturtle excluder device” to get the exact phrase

    • Always limit to full-text, if it is what you need.

    • Notice what appears when you start to type “turtle”. How many results do you get? How does it change when you add “excluder”. How about “exclud*”?

    • Focus on results, and LEFT sidebar

      • Notice the number of hits for each Source Type.

      • Notice other “limiters”. Which are useful for our search?

5. Searching Strategy: Limiters


    • Notice the number of hits for each Source Type.

    • Use checkbox “limiters” on the LEFT sidebar to LIMIT your search by:

      • Etc.

      • Source Type (only Academic Journals? Magazines? Newspapers?)

      • Publication Date

      • Full-text.

  • When you identify a good source/article:

    • Choose a relevant article, and notice the related SUBJECTS.

    • Follow up on subject leads that appear in relevant articles. Remember, hey were chosen by humans: (how about “TURTLE excluder devices”, “BYCATCHES (Fisheries)”?).

    • Save your chosen results to avoid losing stuff (use personal lists, email, notes/citation tools, etc.). Add a user name and password to save searches and results.

Cournoyer: Shipwreck and Ocean Exploration

Shipwreck and Marine Exploration

Understanding Shipwreck and Marine Exploration



Woods Hole Oceanographic Institution has online materials about Underwater Archaeology, including exhibitions of three major underwater sites, including the Titanic and a sunken passenger aircraft.

Don’t forget to look at the technology used by Woods Hole at their Advanced Imaging and Visualization Laboratory.




The Maritime Archaeology Trust is a registered charity in England, involved in research, investigations and pioneering techniques for the study of marine cultural heritage. Start with their explanation titled “What is maritime archaeology?”, and then you can start to explore the incredible wreck sites through the interactive pages.

Nautilus Live, is a project carried out by the The Ocean Exploration Trust, founded by Titanic-discoverer and National Geographic Explorer-in-Residence Dr. Robert Ballard, is dedicated to scientific exploration of the ocean floor. Live feeds of ocean exploration, and images and videos of past explorations are available on the site. Woods Hole Oceanographic Institution has online materials about Underwater Archaeology, including exhibitions of three major underwater sites, including the Titanic and a sunken passenger aircraft.

Don’t forget to look at the technology used by Woods Hole at their Advanced Imaging and Visualization Laboratory.


The National Marine Sanctuaries site from NOAA’s National Ocean Services includes various shipwreck histories and explorations.


Shipwrecks: The Antikythera

The Antikythera Wreck is of huge historical significance to Greek maritime history, because it sheds new light on the sophistication of ancient sailing technology.The wreck has remained largely intact, because of the difficulty of exploring the ocean site.

Read the article High-tech Dives on an Ancient Wreck, that describes the incredible technology needed for this challenging project, including the “exosuit” used in the exploration.



Shipwrecks: The HMS Victory,1774: The Greatest Warship


“The HMS Victory was launched in 1737 and later became the flagship of the

Channel Fleet. She was lost less than a decade later during a violent storm in October 1744. Victory is unique: the only scientifically-studied wreck of a First Rate English warship.” Explore the Victory.
