Southwest Research Institute is presently managing a relatively large program in offshore ecology for the Bureau of Land Management (BLM), Department of the Interior.
The objective of the studies reported in this paper was to obtain facts about the present status of the sea life on and near two offshore structures and compare the quantity and quality of life there now with that which lived at the tower several years
Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems.
To investigate the effects of drilling discharges on the seabed fauna, surveys were carried out in the Beatrice oilfield after drilling 13 wells with water-based muds, and then after one and five further wells had been drilled using low toxicity oil-ba
From Significant Results: Task 1: In this study we collected 18 kelp bass (Paralabrax clathratus), 80 kelp rockfish (Sebastes atrovirens), and 98 Pacific sanddab (Citharichthys sordidus) from five offshore oil platforms and
In a study of the fouling communities of petroleum platforms near the Louisiana coast, scraped samples were collected by divers at depths from 1 to 30 m.
A biological survey was made following an uncontrolled gas flow at a gas well in the North Sea in May 1983. The survey indicates that no lethal and sublethal effects were detectable amongst the macrobenthic fauna living on the jacket of the platform.
