The bathymetry of Coco's Island (UNESCO Natural and Cultural World Patrimony), located approximately 500 km from the Pacific coast of Costa Rica, is not well known. It has a high marine biodiversity and also represents a meeting site for many species traveling throughout the Pacific Ocean. The insular shelf is irregular in extension and also in bathymetric features. The northeast limit is defined by the 109.8-128.1 m contours (60-70 fathoms) while the 183 m contour (100 fathoms) practically defines the rest of the island, from which the depth gradient is steep. The maximum extension is to the northeast with a longitude of 13 km. In this context the present limits of the marine park (5 km), are insufficient to protect the whole insular shelf. Current regulation should be modified to prevent fishing activities less than 15 km from the Island.
科科斯岛（联合国教科文组织自然与文化世界遗产）位于距哥斯达黎加太平洋海岸约500公里处，其海底地形尚不为人所知。该岛拥有高度的海洋生物多样性，也是许多在太平洋中迁徙的物种的交汇地。岛架在范围和海底地形特征上都不规则。东北边界由109.8 - 128.1米等高线（60 - 70英寻）界定，而183米等高线（100英寻）实际上界定了该岛的其余部分，从这里开始深度梯度很陡。最大延伸方向是东北，长度为13公里。在这种情况下，目前海洋公园的范围（5公里）不足以保护整个岛架。应修改现行规定，以防止在距离该岛不到15公里的区域进行捕鱼活动。
