Catch number of true tuna (Thunnus spp.) larvae collected in the Gulf of Mexico before (2007-2009), during (2010), and after (2011-2013; 2015) the Deepwater Horizon Oil Spill (DWHOS)

Catch number of true tunas (Thunnus thynnus [bluefin tuna], T. albacares [yellowfin tuna], T. obesus [bigeye tuna] and T. atlanticus [blackfin tuna]) before, during, and after the oil spill will be compared to improve our understanding of the causes of temporal variability as it relates to the DWHOS. This dataset contains historical catch data from 2007-2015 collected in the northern Gulf of Mexico. Generalized additive models will be developed for periods before the event (2007-2009) to characterize habitat associations of each species, and then used to estimate the spatial extent of suitable habitats of true tunas (2010-2015) and identify areas of high quality habitat that overlapped with regions exposed to surface oil. Sampling data from 2015 are available in dataset R4.x257.227:0002.

真金枪鱼（包括蓝鳍金枪鱼Thunnus thynnus、黄鳍金枪鱼T. albacares、大眼金枪鱼T. obesus及黑鳍金枪鱼T. atlanticus）在石油泄漏事件前、中、后的捕捞数量将被对比分析，以加深我们对与DWHOS相关的时间变异性成因的理解。本数据集包含2007-2015年在墨西哥湾北部采集的历史捕捞数据。将针对事件前时期（2007-2009年）构建广义可加模型（Generalized Additive Model），以刻画各物种的栖息地关联特征；随后利用该模型估算2010-2015年真金枪鱼适宜栖息地的空间范围，并识别与表层石油污染区域重叠的高质量栖息地。2015年的采样数据可在数据集R4.x257.227:0002中获取。
