Report of the 2nd National Ecosystem Modeling Workshop (NEMoW II) : Bridging the Credibility Gap - Dealing with Uncertainty in Ecosystem Models
The following document addresses the terms of reference (TOR) such that a group of scientists forming the National Ecosystem Modeling Workshops (NEMoWs) could explore the facets of ecosystem model (EM) uncertainty and make pragmatic suggestions of how the NMFS could proceed in its EM endeavors by dealing with uncertainty using a suite of "best practices" recommended herein.

Rehabilitation of the South Jetty, Ocean City, Maryland
Partial abstract: Frequent dredging requirements and scouring at the foundation of Ocean City Inlet's south jetty resulted in a study to determine the source of the shoaling and scouring. The study concluded that sand was being transported northward along Assateague Island, through and over the south jetty, and deposited inside the inlet. The sand was then transported north by ebb currents where it encroached on the Federal navigation channel. A rehabilitation program was initiated to create a littoral barrier to eliminate the shoaling problem and to repair the scour hold. Three headland breakwaters were constructed to stabilize Northern Assateague Island. The site was selected as part of the Monitoring Completed Coastal Projects (MCCP) Program to determine how well the rehabilitation project accomplished its design purpose.

Primary Productivity by Phytoplankton in the Tidal, Fresh Potomac River, Maryland, May 1980 to August 1981
Purpose and scope: The purpose of this study was to determine primary productivity and respiration of the fresh, tidal Potomac River. The data will be used by the authors and other researchers involved in modelling chemical and biological properties to calculate phytoplankton growth rates. Methods are documented in detail so that the report could serve as a reference. The report covers the period from May 1980 through August 1981. Five stations were selected for study that are representative of biologically important reaches of the fresh, tidal Potomac River.
