This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Concerns were expressed by Snow Crab harvesters in the Newfoundland and Labrador region about the potential impacts of seismic oil and gas surveying on catch rates near commercial fishing areas. The impacts of ocean noise are a known societal concern, heightened by significant gaps in ecological understanding of the potential existing and future long-term effects on marine life. This study, funded by the Environmental Studies Research Fund (ESRF), was conducted in collaboration with local stakeholders, with significant participation from the snow crab fishing industry, from the planning stages through to completion. The purpose of this project was to examine effects of seismic exploration on the commercial Snow Crab fishery"--Executive summary, page 5.

Book excerpt: Concern has been expressed by commercial fishermen that seismic surveys may affect the health and/or behaviour of snow crab. This study examines the effects of seismic survey air gun noise on snow crab & snow crab catches. The study investigated a number of health, behavioural, & reproductive variables before, during, & after seismic shooting in a preliminary attempt to assess potential effects on physical, biochemical, or activity patterns in subject crabs. The study site was Conception Bay, Newfoundland, an area considered to be typical prime crab grounds. Fishing experiments were conducted in a controlled manner using standard & modified crab traps, with seven sets prior to shooting and six afterward. Crab movement & behaviour after exposure to air gun shots was monitored for caged crabs by video camera and for transmitter-tagged crabs by hydrophones. Caged crabs were also exposed to air gun shots at various depths and were sampled to assess potential indicators of stress & physical damage, in comparison to control crabs not exposed to shots. An important component of that study was to determine if lethal effects occurred three months after exposure. Results of this research are presented & discussed and direct effects on crab physiology are summarized.

Book excerpt: While these results do not support the hypothesis of organ fouling due to the dragging of cages in the ensonified area, a definitive conclusion could not be reached, since the two-hour duration of the study was considerably shorter than the 12-day caging period during the December 2003 seismic survey. [...] Because of the lack of knowledge on the potential impacts of such a survey on local snow crab populations, an Environmental Effects Monitoring (EEM) research program, funded by the Environmental Studies Research Funds (ESRF) of the National Energy Board (NEB), was developed by the CRI, the Department of Fisheries and Oceans (DFO) and the Area 19 Snow Crab Fishermen's Association. [...] The main objectives of the scientific study were to assess the effects of seismic exploration on the survival of adult female snow crab; survival, morphological development, and locomotion of snow crab larvae from exposed females; and to conduct a histopathological analysis of exposed females. [...] Chapter 2 discusses the investigation of the effect of the dragging of cages on gill fouling and the evaluation of current stock assessment data for evidence of reduced snow crab abundance within the December 2003 seismic survey area (meeting of January 23, 2007, items 2 and 3). [...] Chapter 3 discusses the results of the verification by an independent histopathologist of the interpretations made in September 2004 of the gonad and hepatopancreas tissue from snow crab caged within and outside the seismic survey area (meeting of January 23, 2007, item 1).

Book excerpt: This report summarizes the results of a study on the potential impacts of seismic energy on snow crab (Chionoecetes opilio). It focusses in particular on whether there was any evidence to indicate the following: irreversible harm to female snow crab; mortality or morbidity in females carrying eggs; long-term effects on behaviour; long-term effects on the characteristics and morphology of gills and internal organs; effects on the hatch of embryos carried by exposed female snow crab and subsequent morphology and locomotion of larvae. The report also identifies areas for further research.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy (DOE), in conjunction with the Bureau of Land Management (BLM), has prepared an Environmental Assessment (DOE/EA-1124) to identify and evaluate the potential environmental impacts of the proposed geophysical seismic survey on and adjacent to the Naval Petroleum Reserve No. 1 (NPR-1), located approximately 35 miles west of Bakersfield, California. NPR-1 is jointly owned and operated by the federal government and Chevron U.S.A. Production Company. The federal government owns about 78 percent of NPR-1, while Chevron owns the remaining 22 percent. The government's interest is under the jurisdiction of DOE, which has contracted with Bechtel Petroleum Operations, Inc. (BPOI) for the operation and management of the reserve. The 3-dimensional seismic survey would take place on NPR-1 lands and on public and private lands adjacent to NPR-1. This project would involve lands owned by BLM, California Department of Fish and Game (CDFG), California Energy Commission (CEC), The Nature Conservancy, the Center for Natural Lands Management, oil companies (Chevron, Texaco, and Mobil), and several private individuals. The proposed action is designed to provide seismic data for the analysis of the subsurface geology extant in western NPR-1 with the goal of better defining the commercial limits of a currently producing reservoir (Northwest Stevens) and three prospective hydrocarbon bearing zones: the[open-quotes]A Fan[close-quotes] in Section 7R, the 19R Structure in Section 19R, and the 13Z Structure in Section 13Z. Interpreting the data is expected to provide NPR-1 owners with more accurate locations of structural highs, faults, and pinchouts to maximize the recovery of the available hydrocarbon resources in western NPR-1. Completion of this project is expected to increase NPR-1 recoverable reserves, and reduce the risks and costs associated with further exploration and development in the area.
