在使科学成为养护的重要事项时，海洋养护从业人员和管理人员必须做好准备，根据现有的最佳科学成果作出适当的决定。近十年来，许多利益攸关方鼓励北太平洋渔业管理委员会制定保护东白令海斜坡几个峡谷的深海珊瑚的措施。2014年，应理事会的要求，阿拉斯加水产科学中心国家海洋渔业局沿东白令海斜坡进行了一次带状样带调查，以验证预测深海珊瑚栖息地发生的模型的结果。超过25万张照片被分析，以估计珊瑚、海绵和海鞭的丰度、分布、高度和对人为破坏的脆弱性。调查结果证实，珊瑚的栖息地和产状集中在Pribilof Canyon和邻近的斜坡周围。研究结果还证实，东白令海的珊瑚密度很低，即使在它们出现的地方也是如此。在审查了现有的最佳科学信息后，理事会得出结论，没有科学证据表明，在目前的管理结构下，东白令海斜坡或峡谷的深海珊瑚面临商业渔业的风险，没有必要对深海珊瑚进行特别保护。
When making science matter for conservation, marine conservation practitioners and managers must be prepared to make the appropriate decision based on the results of the best available science used to inform it. For nearly a decade, many stakeholders encouraged the North Pacific Fishery Management Council to enact protections for deep-sea corals in several canyons in the Eastern Bering Sea slope. In 2014, at the request of the Council, the National Marine Fisheries Service, Alaska Fisheries Science Center conducted a strip-transect survey along the Eastern Bering Sea slope to validate the results of a model predicting the occurrence of deep-sea coral habitat. More than 250,000 photos were analyzed to estimate coral, sponge, and sea whip abundance, distribution, height and vulnerability to anthropogenic damage. The results of the survey confirmed that coral habitat and occurrence was concentrated around Pribilof Canyon and the adjacent slope. The results also confirmed that the densities of corals in the Eastern Bering Sea were low, even where they occurred. After reviewing the best available scientific information, the Council concluded that there is no scientific evidence to suggest that deep-sea corals in the Eastern Bering Sea slope or canyons are at risk from commercial fisheries under the current management structure, and that special protections for deep-sea corals were not warranted.
