海隆是在养护和生物多样性方面以及在深海和深海鱼种渔业方面具有重大意义的生境。收集了20个以前汇编的数据集，包括海山/水下特征清单、测深图和不同来源（船舶和卫星测高）在不同空间尺度（从单独巡航到全球卫星数据）的新特征图，以汇编西太平洋和中太平洋部分地区的水下特征增强清单。KL 04数据集[Kitchingman，A.，和Lai，S.，2004.根据中分辨率测深数据推断潜在海山位置。渔业中心研究报告12（5），7-12]列出了根据卫星测高得出的水深测量计算的海山位置和深度，为这项研究提供了基线数据，因为它涵盖了整个有关区域，并包括山顶深度信息。所有KL 04潜在海山都与其他数据集进行了交叉核对，以删除任何被错误归类为海山的环礁和岛屿，添加KL 04未发现的海山，更新整个数据库（地理位置、深度、海拔和名称），并汇编不同类型水下地貌的12级类型学。在KL 04确定的4 626座潜在海山中，有719座是同一大型水下地物的多次确定，373座（10%）实际上是露出的岸滩、环礁和岛屿，剩下3 534座实际水下地物。相反，其他数据集中记录了487个水下特征，但KL 04没有记录。对所有潜在的中西太平洋海洋保护组织海山进行筛选后，产生了一份载有商定位置和信息的4 021个水下地貌的最后清单。这一扩大的清单在海洋学、生物多样性养护和海隆对远洋生态系统和渔业影响的研究方面应具有许多用途。(c)2008爱思唯尔有限公司保留所有权利。
Seamounts are habitats of considerable interest in terms of conservation and biodiversity, and in terms of fisheries for bentho-pelagic and pelagic species. Twenty previously compiled datasets including seamount/underwater feature lists, bathymetric maps and emerged feature maps from different sources (ship-derived and satellite altimetry-derived) at different spatial scales (from individual cruise to worldwide satellite data) were gathered in order to compile an enhanced list of underwater features for parts of the western and central Pacific Ocean (WCPO). The KL04 dataset [Kitchingman, A., and Lai, S., 2004. Inferences on potential seamount locations from mid-resolution bathymetric data. Fisheries Centre Research Reports 12 (5), 7-12], listing seamount positions and depths as calculated from satellite altimetry-derived bathymetry, provided the baseline data for this study as it covered the entire region of interest and included summit depth information. All KL04 potential seamounts were cross-checked with other datasets to remove any atolls and islands that had been incorrectly classified as seamounts, to add seamounts undetected by KL04, to update the overall database (geolocation, depth, elevation, and name) and to compile a 12-class typology of the different types of underwater features. of the 4626 potential seamounts identified in KL04, 719 were multiple identifications of the same large underwater features and 373 (10%) were actually emerged banks, atolls and islands, leaving 3534 actual underwater features. Conversely, 487 underwater features were documented in other datasets but not registered by KL04. The screening of all the potential WCPO seamounts produced a final list of 4021 underwater features with agreed upon position and information. This enhanced list should have many applications in oceanography, biodiversity conservation and studies of the influence of seamounts on pelagic ecosystems and fisheries. (c) 2008 Elsevier Ltd.
