Improving methods and indicators for evaluating coastal water eutrophication: A pilot study in the Gulf of Maine

Study Goals and Objectives: 1) Improve existing nutrient-related eutrophication assessment methods, updating (from early 1990s to early 2000s) the eutrophication assessment for systems included in the study with the improved method. 2) Develop a human-use/socioeconomic indicator to complement the assessment indicator. The human-use indicator was developed to evaluate costs of nutrient-related degradation in coastal waters … Read more

Temporal and Spatial Aspects of Bottlenose Dolphin Occurrence in Coastal and Estuarine Waters near Charleston, South Carolina

The spatial and temporal occurrence of Atlantic bottlenose dolphins (Tursiops truncatus) in the coastal and estuarine waters near Charleston, SC were evaluated. Sighting and photographic data from photo-identification (ID), remote biopsy, capture-release and radio-tracking studies, conducted from 1994 through 2003, were analyzed in order to further delineate residence patterns of Charleston area bottlenose dolphins. Data … Read more

Human Use Pharmaceuticals in the Estuarine Environments: A Survey in the Chesapeake and Biscayne Bays

The goal of this pilot project was to assess the presence of a number of commonly prescribed human use pharmaceuticals in three coastal areas of the U.S. Water samples were collected in conjunction with three NOAA monitoring/research projects to assess sediment contamination, macrobenthic infaunal communities, and bioeffects in the Chesapeake Bay, Biscayne Bay, and the … Read more

A Biogeographic Assessment off North/Central California: In Support of the National Marine Sanctuaries of Cordell Bank, Gulf of the Farallones and Monterey Bay. Phase II Environmental Setting and Update to Marine Birds and Mammals

This document is Phase II of a biogeographic assessment completed in 2004, described below. In the spring of 2001, NOAA’s National Marine Sanctuary Program (NMSP) and National Centers for Coastal Ocean Science (NCCOS) launched a project to assess biogeographic patterns of selected marine species and habitats found within and adjacent to the boundaries of three … Read more

Preliminary report on bottlenose dolphin (Tursiops truncates) uterine samples for parity analysis

There have been numerous studies on various mammalian species regarding vascular changes in uterine arteries elucidating the effects of parity. In equids, vascular changes of uterine arteries have been demonstrated to occur in uniparous and multiparous mares. The severity of these arteriole changes suggests a link to previous pregnancies. Differences in the number or range … Read more

A pilot study to determine the movements of buoy line used in the crab pot fishery to assess bottlenose dolphin entanglement

A pilot study on the characteristics of crab pot buoy line movements to assess bottlenose dolphin entanglement was conducted from 19 September to 30 September 2005 in the Charleston Harbor, Charleston, South Carolina. The objectives of this study were to determine: 1) the movements of the buoy line in the water at various tidal stages, … Read more

Spatial and temporal analysis of bottlenose dolphin strandings in South Carolina, 1992-2005

This report contains summary data of bottlenose dolphins stranded in South Carolina. The intent of this report is to provide data on bottlenose dolphin strandings in South Carolina to marine mammal researchers and managers. This report is an accumulation of 14 years of stranding data collected through the collaborations of the National Ocean Service, Center … Read more

Comparative Microbial Dynamics in Crassostrea virginica and Crassostrea ariakensis

Considerations to introduce the Suminoe or Asian oyster Crassostrea ariakensis along the East Coast have raised many questions regarding ecology, economics, and human health. To date, research has focused primarily on the ecological and socioeconomic implications of this initiative, yet few studies have assessed its potential impact on public health. Our work compares the rates … Read more

Biology, Ecology, Control and Management of the Invasive Indo-Pacific Lionfish: An Updated Integrated Assessment

Venomous Indo-Pacific lionfish (Pterois miles and P. volitans) are now established along the Southeast U.S.A. and parts of the Caribbean and pose a serious threat to reef fish communities of these regions. Lionfish are likely to invade the Gulf of Mexico and potentially South America in the near future. Introductions of lionfish were noted since … Read more

Status of Contaminant Levels in Biota and Sediments of the St. Lucie Estuary

This NOAA study was one of the eight selected for funding by the St. Lucie River Issue Team (SLRIT) in the Year 2000. The study purpose was to characterize St. Lucie Estuary in terms of environmental toxicity and to describe the extent and severity of habitat degradation using the sediment quality triad approach. The study … Read more
