Using platforms of opportunity to determine the occurrence and group characteristics of orca (Orcinus orca) in the Hauraki Gulf,New Zealand

We present the first fine-scale data relating to the occurrence and group characteristics for killer whales (Orcinus orca) in the Hauraki Gulf, New Zealand, as observed from a platform of opportunity (PoP). Group size and composition were examined in relation to water depth and sea surface temperature (SST). From 2000 to 2010, 119 orca encounters were recorded, involving 1 to 18 animals. The encounter rate varied seasonally, being highest in austral spring and lowest in summer. Water depth in which whales were observed was significantly affected by group composition. Sixty-seven percent of groups contained immature animals. Group size was highly skewed towards smaller groups comprising two animals. While this study illustrates that PoPs can be used to indicate the occurrence and group characteristics of highly mobile social species, biases clearly exist. Through identifying such inaccuracies, we present recommendations on how future data should be collected to minimise error and improve datasets for scientific use.

济阳坳陷邵家地区沙四段油气成藏差异性及其定量评价

济阳坳陷邵家地区沙四段勘探目标多、油气分布不均一且对油气成藏规律认识程度较低,给油气勘探工作带来较大困难。为了能够直观地认识油气成藏差异特征,并可以快速方便地为油气勘探决策部署提供有效指导意见,对研究区沙四段开展成藏差异性定量评价研究。在立足于已有勘探成果的基础上,按照含油气系统区带圈闭分层次对其油气成藏差异性特征进行系统剖析,并充分利用改进的区带与圈闭评价方法以及借助于统计挖掘等数学手段进行定量表征评价。结果表明：总体上研究区沙四段油气成藏差异明显,油源、储层及运聚条件是影响油气成藏差异性的主要因素;北部断阶带成藏条件优越,仍是主要的滚动勘探区,评价出的1类圈闭可作为优选的钻探目标;南部缓坡带成藏条件变化较大,通过加大勘探则有望成为油气资源接替区;西部断裂带成藏条件总体较差,勘探风险较高,局部可作为油气潜力区。开展的成藏差异性定量评价可以有效降低油气勘探成本,深化油气成藏认识,对类似地区的油气效益勘探具有一定借鉴意义。
