Deferred Revenue	12 Months Ended

Deferred Revenue [Abstract]
Deferred Revenue	NOTE N – DEFERRED REVENUE Since 2009, we entered into several marine search services contracts associated with the Robert Frasier Marine, Ltd. projects. For each contract, revenue is recognized over the contractual period when services are performed as defined by the contract. The period of time a search project remains active varies but usually extends over several months and may be accelerated or extended depending upon operational factors. At December 31, 2011, we have a $3,545,140 service obligation on two service contracts that will be recognized as revenue over the period of time the contractual services are provided. At December 31, 2010, we had deferred revenue related to a specific contract of $730,098 which was earned in 2011. For the years ended December 31, 2011 and 2010, we earned charter expedition revenue, exclusive of the sale of research, of $2,708,947 and $5,846,793, respectively, relating to these contracts.

- Definition

The entire disclosure for deferred revenues at the end of the reporting period, and description and amounts of significant changes that occurred during the reporting period. Deferred revenue is a liability as of the balance sheet date related to a revenue producing activity for which revenue has not yet been recognized. Generally, an entity records deferred revenue when it receives consideration from a customer before achieving certain criteria that must be met for revenue to be recognized in conformity with GAAP.
