This technical report reviews the placement of dredged sediment at ocean dredged material disposal sites (ODMDS) from 1976-2015. This report uses data obtained from the Ocean Disposal Database (ODD), a repository of ocean disposal data submitted by USACE Districts. These data are collected in order to fulfill the London Convention (LC) obligations to report annually the amount and location of dredged sediments placed in ocean waters. The LC report is published annually, but until now, a long-term compilation analysis of the ODD dataset has never been conducted. Analyzing the database for long-term trends shows that the ODD can help answer questions related to policies concerning placement of dredged sediments in ocean waters. Additionally, historical trends provide the USACE with information about ODMDS activity to assist in the short- and long-term management of dredged sediment placed at these sites. There is limited ancillary data outside of the required data fields to support LC reporting activities. Therefore, this report leaves open the possibility for further research into the reasons for the observed trends. In order to better understand ODD trends, it is recommended that data from other related databases be integrated into a broader and more comprehensive framework.
