简介：为弥补测高数据在近海区域因为编辑准则被剔除而导致近海测量数据质量不高的缺点,利用5参数模型的两种形式和Ice-2模型对Jason-2卫星在中国南海部分海域的海洋回波波形进行了波形重跟踪的研究,并选择20个海洋回波波形,依据最小二乘原理进行计算、分析、对比,发现5参数模型的指数形式的结果和Ice-2模型结果非常接近.研究结果表明,在开阔的海域,对Jason-2波形进行3种方法波形重跟踪时,可以优先考虑Ice-2模型.波形重跟踪技术能够提高卫星测高数据利用率,为科学研究提供可靠的数据保障.

简介：《海洋环境保护法》第89条第2款本身并非关于诉讼的直接规定,该款规定的内容也不符合民事公益诉讼的内涵特征,将该款解释为关于海洋环境民事公益诉讼的规定不利于我国立法内部的横向协调。我国司法实践总体上也不认可《海洋环境保护法》第89条第2款规定的内容属于海洋环境民事公益诉讼。《海洋环境保护法》第89条第2款应是关于损害赔偿请求权的特别规定,不是我国海洋环境民事公益诉讼的法律依据,相应的法律依据应是《环境保护法》第58条、《民事诉讼法》第55条以及相关司法解释。
