Book Long term Monitoring of Ecological Conditions in Gray s Reef National Marine Sanctuary

Download or read book Long term Monitoring of Ecological Conditions in Gray s Reef National Marine Sanctuary written by William Leonard Balthis and published by . This book was released on 2015 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Since April 2000, NOAA's National Centers for Coastal Ocean Science (NCCOS) and the Office of National Marine Sanctuaries (ONMS) have been engaged in a collaborative partnership to augment the management of National Marine Sanctuaries (NMS) through increased scientific understanding of sanctuary sites (ONMS/NCCOS 2004). NCCOS scientists have been working with Gray's Reef NMS (GRNMS) to assess the status of ecological condition and stressor impacts throughout the sanctuary and surrounding shelf areas, with a major focus on the soft-bottom benthos and sediment quality. Such activities are important to fulfill key research and monitoring goals for GRNMS in supporting scientific research and long-term monitoring to enhance the understanding of the Sanctuary environment and to improve management decision-making (NOAA 2014)...An initial characterization of GRNMS was conducted in spring 2000 to evaluate the condition and distribution of benthic macroinfauna, including sediment-associated stressors, to provide a quantitative benchmark for tracking any future changes due to natural or human disturbances. The results of the spring 2000 survey suggested that soft-bottom habitats associated with GRNMS support highly diverse infaunal assemblages, thereby challenging a commonly-held assumption that these relatively featureless expanses of substrate surrounding "live bottom" habitat are biological voids (Cooksey et al 2004, Hyland et al. 2006). Levels of man-made, chemical contaminants were found at low, but detectable, concentrations in sediments and edible tissues of target species (black sea bass, turkey wing arks), suggesting background conditions while highlighting the need for future monitoring to track potential changes in levels of these substances. A follow-up survey in spring 2005 (Balthis et al. 2007) found similarly low levels of contaminants in sediments and fish and shellfish tissues, with measured concentrations being well below corresponding sediment quality and human health guidelines. Similar patterns in species richness and diversity of softbottom benthic assemblages also were observed in 2000 and 2005. This report presents the results of a follow-up survey, conducted in summer 2012/spring 2013, which provides additional data points for the long-term monitoring record as a basis for tracking status and trends in sanctuary conditions and supports important management products such as the GRNMS management plan (NOAA 2014) and GRNMS Condition Reports (ONMS 2008)"--Introduction.

Book Effects of Trawling and Dredging on Seafloor Habitat

Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Book Marine Anthropogenic Litter

Download or read book Marine Anthropogenic Litter written by Melanie Bergmann and published by Springer. This book was released on 2015-06-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Book Advances in the Studies of the Benthic Zone

Download or read book Advances in the Studies of the Benthic Zone written by Luis Soto and published by BoD – Books on Demand. This book was released on 2020-06-10 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an unpretentious editing venture to fill the gap in our current knowledge on the ecological implications caused by anthropogenic disturbances upon benthic communities in several regions of the world, including the Western Atlantic, the Mediterranean Sea, and the Eastern Pacific Ocean, as well as the pristine environments of the Andes in South America. The common goal of the contributing authors in this book was to unravel the complex processes that make possible the life existence of bottom-living animals in different environmental scenarios. To achieve such a goal, the authors focus their attention on the emerging issues inherent to global climate change or the pollution of aquatic systems. These are all themes that might be of interest to scientists active in a wide range of oceanographic subdisciplines. Well-established researchers would appreciate the innovative approach adopted in each chapter of the book, which extends from the ecosystem level to refined molecular interpretations.
