Here is what I found on Floridas Isolated Finds Law. It does not say anything about the beach or ocean. I did however find this statement-- "analysis of the IFP database examined Isolated Finds reports from May 1996 ... Artifacts have been reported from 27 rivers/creeks, 3 lakes, one beach, and one sinkhole."
Isolated Finds:The Isolated Finds Program (IFP) allowed divers to legally collect artifacts (e.g., arrowheads, pottery sherds) from some Florida rivers by reporting information on their finds to the Division of Historical Resources.
§ 267.115(9), Florida Statutes states that "the division may implement a program to administer finds of isolated historic artifacts from state-owned river bottoms whereby the division may transfer ownership of such artifacts to the finder in exchange for information about the artifacts and the circumstances and location of their discovery."
Artifacts were not to be collected from known archaeological sites or from rivers within managed areas like parks, preserves and forests.
The IFP began in 1996 as a cooperative effort between the Division and river divers who were concerned that their long standing hobby was jeopardized by increased criminal penalties for removing artifacts from State of Florida owned lands.
The Division attempted to inform river divers about the IFP with flyers, public presentations, meetings with river divers, and a web page.
In November 2003 the Florida Historical Commission recommended that the Division discontinue the IFP and explore alternative programs. This decision was based on low participation and problems with enforcement of the IFP.
The Division held public meetings in April and June 2004 to receive input on the IFP and possible alternative programs. Letters requesting input were sent to IFP participants, avocational and professional archaeological societies, American Indian tribes, land managing and law enforcement agencies.
The Historical Commission discussed this issue and received public comment at its meetings in Delray Beach (May 15, 2004) and Tallahassee (November 15, 2004 and April 7, 2005).
The Division's review of the IFP was presented to the Historical Commission in May 2005. The Commission unanimously recommended that the Division discontinue the IFP without a replacement program.
The Division accepted the recommendation of the Historical Commission and notified IFP participants and other interested parties that the IFP was discontinued as of June 1, 2005. Participants were encouraged to continue their interests in Florida archaeology by working with scholars and archaeological societies.
Between June 1996 and June 2005 the Division received 1,115 IFP reports from 150 individuals. Seven individuals submitted 54 % of the IFP reports received.
10,720 artifacts were collected under the IFP program from 51 rivers and lakes. In two cases divers reported locating significant sites and donated their finds to the Division; in all other cases the artifacts were kept by the finders.
Geographic analysis indicates that 10 % of the IFP reports represent artifacts removed from known archaeological sites.
In the absence of the IFP removal of artifacts from river bottoms and other sovereign submerged lands is a first degree misdemeanor under § 267.13(1)(a), Florida Statutes. --------------------------------------------------------------------------------
