The information in the following report was gathered from web-based searches, email communication with colleagues, and phone conversations. This material was gathered to assist guidance counselors, teachers, and minority students potentially interested in marine science or science education of the available opportunities for education and training, and provide information on scholarships and internships. Although we … Read more

Ecological Forecasting: New Tools for Coastal and Marine Ecosystem Management

Policy makers, natural resource managers, regulators, and the public often call on scientists to estimate the potential ecological changes caused by both natural and human-induced stresses, and to determine how those changes will impact people and the environment. To develop accurate forecasts of ecological changes we need to: 1) increase understanding of ecosystem composition, structure, … Read more

This report is the third in an ongoing series of assessments of the condition of coral reef ecosystems in the United States and Pacific Freely Associated states, and the second report to focus specifically on summarizing the results of coral reef ecosystem monitoring activities carried out by federal, state, territorial, commonwealth, private, academic, and nongovernmental … Read more

Coastal Ecosystem Assessment of Chesapeake Bay Watersheds: Land Use Patterns and River Conditions

In coastal and estuarine regions, land use can have a profound impact on aquatic ecosystem health. In the Chesapeake Bay watershed, agriculture and urbanization have transformed major portions of the landscape, though some areas of undeveloped land remain. This document assesses the health of six Bay tributaries with different land use profiles via a suite … Read more

WEMo (Wave Exposure Model): Formulation, Procedures and Validation

This report describes the working of National Centers for Coastal Ocean Service (NCCOS) Wave Exposure Model (WEMo) capable of predicting the exposure of a site in estuarine and closed water to local wind generated waves. WEMo works in two different modes: the Representative Wave Energy (RWE) mode calculates the exposure using physical parameters like wave … Read more

A surveillance strategy for invasive species of concern in deepwater habitats of the Northwestern Hawaiian Islands

This document provides strategies to detect deepwater invasive species in the Northwestern Hawaiian Islands (NWHI) in support of the Papahanaumokuakea Marine National Monument (PMNM). The strategies use technical diving to conduct visual surveys and focus on two invasive species of growing concern, the octocoral Carijoa riisei and the red alga Hypnea musciformis. Both of these … Read more
