Seismic Blasting - Center for Biological Diversity

Seismic testing involves blasting the seafloor with high-powered airguns (a kind of powerful horn) every 10 seconds and measuring the echoes with long tubes to map offshore oil and gas reserves. These blasts disturb, injure and kill marine wildlife around the clock for years on end. In marine mammals, the blasts — which reach more than 250 ...

Lawsuit Challenges Seismic Oil, Gas Testing in Gulf of Mexico ...

In January NMFS scientists published a paper recognizing the Gulf of Mexico whale as a unique species, making it the only species of baleen whale believed to reside entirely off the United States. Last year NMFS found that oil and gas activities, including seismic testing, would jeopardize the whales’ continued existence if allowed to proceed without sufficient protection.

A Review of the Impacts of Seismic Airgun Surveys on Marine Life

Parente et al. (2007) discovered a reduction in cetacean species diversity with increasing numbers of seismic surveys during 2000 and 2001 off Brazil, despite no significant oceanographic changes in this period. Between 1999 and 2004, there was a negative relationship between cetacean diversity and the intensity of seismic surveys.

NRDC and partner groups Healthy Gulf, Center for Biological Diversity, the Association of Zoos and Aquariums, and the Surfrider Foundation sued the National Marine Fisheries Service (NMFS) today over a Trump administration decision to allow extensive seismic airgun testing in the Gulf of Mexico, with minimal protections for marine animals.

Seismic Exploration Permits | Louisiana Department of ...

Seismic exploration uses energy waves to generate a profile of subsurface reflective layers that help define potential oil and gas traps. The energy waves can be produced by explosives detonated below the ground, air guns that emit a burst of air at the surface of waterbodies, large vibrating pads placed on the surface, or other energy sources.

Protecting Wildlife Diversity | Louisiana Department of ...

The Wildlife Diversity Program maintains a geospatial database of these species and habitats. These data are vital for reviewing proposed construction projects to determine potential adverse impacts to the environment and providing guidance to prevent, minimize, or mitigate such impacts.

A large-scale experiment finds no evidence that a seismic ...

Seismic surveys are used to locate deposits of oil and gas in seabeds throughout the world’s oceans. There are conflicting views on the impact of these surveys on fish fauna and whether they harm commercial catches. To resolve this issue, we conducted an experimental seismic survey and monitored the composition, abundance, behavior, and movement of an assemblage of commercially important ...

Species diversity - Wikipedia

Species diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant).
