GEOBASE is a database of indexed research literature unequalled in its coverage of the international geoscience literature: Earth sciences, ecology, geology, human and physical geography, environmental sciences, oceanography, geomechanics, alternative energy sources, pollution, waste management and nature conservation. The content crosses subject, language and cultural boundaries, providing a unique research tool to users.

GEOBASE covers 2,772,739 abstract records of multidisciplinary content enabling comprehensive geological evaluation of any desired region. This includes geological structure and relation to natural resources as well as linking resource management, transport, and regional and urban planning.

Segments and Years of Coverage
ELGE 2004 to Present
ELGE3 1994 to 2003
ELGE2 1990 to 1993

Advanced Searching
You can use special search syntax listed below to combine search terms or strategically develop a search. Full documentation is provided in the Advanced Searching Techniques section of the Online Help.
Operator Syntax Search Example Sample Results
OR x or y

snake river or columbia river

"Estimating season-wide survival rates of outmigrating salmon smolt in the Snake River, Washington"

The OR operator retrieves records that contain any or all of the search terms. For example, the search heart attack or myocardial infarction retrieves results that contain the terms heart attack, myocardial infarction or both terms; results are all inclusive. You can use the OR operator in both unqualified searches and searches applied to a specific field.
AND x and y

salmon and columbia river

"Evaluation of energy expenditure in adult spring Chinook salmon migrating upstream in the Columbia River Basin"

The AND operator retrieves only those records that include all of the search terms. For example, the search blood pressure and stroke retrieves results that contain the term blood pressure and the term stroke together in the same record; results are exclusive of records that do not contain both of these terms. You can use the AND operator in both unqualified searches and searches applied to a specific field.
NOT x not y

Pliocene not Pleistocene

"Dolichopithecus balcanicus sp. nov., a new Colobinae (Primates, Cercopithecidae) from the early Pliocene of southeastern Europe, with a discussion on the taxonomy of the genus"

The NOT operator retrieves records that contain the first search term and excludes the second search term. For example, the search health reform not health maintenance organizations retrieves only those records that contain the term health reform but excludes the term health maintenance organizations. In this way, you can use the NOT operator to restrict results to a specific topic.
You can use the NOT operator in both unqualified searches and searches applied to a specific field.
Adjacency (ADJ) x y

Pliocene adj Pleistocene

"The Pliocene-Pleistocene boundary: Which significance for the so called 'Wolf Event'? Evidences from Western Europe."

The Adjacent operator (ADJ) retrieves records with search terms next to each other in that specific order. You do not need to separate search terms manually by inserting ADJ between them, because when you separate terms with a space on the command line, Ovid automatically searches for the terms adjacent to one another. For example, the search blood pressure is identical to the search blood adj pressure.
Defined Adjacency (ADJn) x ADJn y

bonneville adj3 utah

"Moisture history and small mammal community richness during the latest Pleistocene and Holocene, northern Bonneville Basin, Utah"

The defined adjacency operator (ADJn) retrieves records that contain search terms within a specified number (n-1) of words from each other in any order (stop-words included). To use the adjacency operator, separate your search terms with ADJ and a number from 1 to 99 as explained below:

           ADJ1     Next to each other, in any order
           ADJ2     Next to each other, in any order, up to 1 word in between
           ADJ3     Next to each other, in any order, up to 2 words in between
           ADJ99   Next to each other, in any order, up to 98 words in between

For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship with a maximum of four words in between in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship between cancer patient and physician.
Please note Ovid’s order of operation handles terms within parentheses first. Therefore it is recommended to apply the ADJn operator in one-on-one operations to avoid missing out on results. E.g. stroke adj4 (blood pressure or high blood pressure) could potentially miss out on some combinations of stroke with high blood pressure. The optimum way to execute this on Ovid is: (stroke adj4 blood pressure) OR (stroke adj4 high blood pressure).
Frequency (FREQ) x.ab./FREQ=n

Baikal.ab./FREQ=2

"Mercury distribution was examined in the sediments of Lake Baikal that were sampled within the scope of the Baikal Drilling International Project in 1996-1999"

The frequency operator (FREQ) lets you specify a threshold of occurrence of a term in the records retrieved from your search. Records containing your search term are retrieved only if the term occurs at least the specified (n) number of times. In general, records that contain many instances of your search term are more relevant than records that contain fewer instances. The frequency operator is particularly useful when searching a text field, such as Abstract or Full Text, for a common word or phrase.
Unlimited Truncation ($) x$

rat$

"Titan's young surface: Initial impact crater survey by Cassini RADAR and model comparison."

Unlimited truncation retrieves all possible suffix variations of the root word indicated. To apply unlimited truncation to a term, type the root word or phrase followed by either of the truncation characters: $ (dollar sign) or * (asterisk). For example, in the truncated search rat*, Ovid retrieves the word rat as well as the words rats, and more.
Limited Truncation ($) x$n

dog$1

"The dog that didn't bark: Would increased electoral turnout make a difference?"

Limited truncation specifies a maximum number of characters that may follow the root word or phrase. For example, the truncated search dog$1 retrieves results with the words dog and dogs; but it does not retrieve results with the word dogma.
Mandated Wildcard (#) xx#y

wom#n

"The role of high school performance in explaining women's rising college enrollment."

Searching with a mandated wildcard retrieves all possible variations of a word in which the wildcard is present in the specified place. You can use it at the end of a term to limit results to only those that contain the word plus the mandated character. For example, the search dog# retrieves results that contain the word dogs, but not those that contain the word dog, effectively limiting results to only those that contain the plural form of the word. The mandated wild card character (#) is also useful for retrieving specialized plural forms of a word. For example, the search wom#n retrieves results that contain both woman and women. You can use multiple wild cards in a single query word.
Optional Wildcard (?) xx?y colo?r

"A proposed stereo matching algorithm for noisy sets of color images."

The optional wild card character (?) can be used within or at the end of a search term to substitute for one or no characters. This wild card is useful for retrieving documents with British and American word variants since it specifies that you want retrieval whether or not the extra character is present. For example, the optional wild card search colo?r retrieves results that contain the words color or colour. You can use multiple wild cards in a single query word.
Literal String ("") "x / y"

"Pumpellyite-(Al)"

"Pumpellyite-(Al), a new mineral from Bertrix, Belgian Ardennes"

"n"

"3".vo

"Journal of Map and Geography Libraries. 3(1)57-78, 2006."

Quotation marks can be used to retrieve records that contain literal strings, when the string includes special characters, such as a forward slash (/).

Quotation marks can also be used to retrieve records that contain numbers that may otherwise be confused for earlier searches. In the example, a search for 3.vo would limit the string from your third search in your search history to the volume field. By including the number in quotation marks, the search will retrieve documents with a 3 in the volume number.

Go: Menu or Back

Stopwords
The Ovid search engine applies so called "run-time stopword processing". This means the search engine on the fly ignores the stopwords: and, as, by, for, from, in, is, of, on, that, the, this, to, was, were & with.

Therefore a search: at risk for diabetes.ti will also find: at risk of diabetes. The distance of one word in between is kept, but the stopword "for" is ignored.

Abstract  
  Uranium concentrations in the rivers of Okinawa Island, Japan were determined in this study. Most rivers in the 
  southwestern area of the island showed high U concentrations, the highest of which was 87 and 11 times the average 
  U levels in Japanese rivers and worldwide, respectively. The U concentration in two rivers exceeded the Japanese 
  guideline for public waters. Thermodynamic calculations revealed that the predominant U species in the rivers was 
  Ca2UO2(CO3)30 (aq) because of high concentrations of calcium and carbonate ions. However, the U concentrations 
  were not explained by either the congruent dissolution of limestone or the input of seawater and/or sea salt aerosols. 
  Therefore, selective dissolution of U from limestone as well as from other rocks and soils via the formation of calcium-
  uranyl-carbonate complexes may be a possible mechanism for the high riverine U concentrations. Copyright 2015 by
