The seaward margin of Belize barrier and atoll reefs : morphology, sedimentology, organism distribution, and late quaternary history /
This first IAS Special Publication contains the oral presentations from a special symposium on pelagic sediments held in Zurich in 1973. The aim of the symposium was to bring together sea-borne researchers involved with the Deep Sea Drilling Project and land-locked researchers studying ancient sedim...
