Planning units layers used in ATLAS spatial prioritization on the North Atlantic

Planning units layers used for ATLAS EU prioritization scenarios on the North Atlantic (18°N to 76°N and 36°E to 98°W). This raster layer is designed on a grid of 25km * 25km resolution, that served to extract all the spatial data used prioritization. The 31 518 planning units (cells with value) corresponded to areas containing depths shallower or equal to 3500m, even if they could also contain deeper areas locally. For connectivity scenarios, only the planning units matching with the extent of available connectivity data were selected. One layer allocates planning units to the 13 geographical provinces (values ranging from 1 to 13) created for the purpose of prioritization.This dataset was built to feed a basin-wide spatial conservation planning exercise, targeting the deep sea of the North Atlantic. The goal of this approach was to identify conservation priority areas for Vulnerable Marine Ecosystems (VMEs) and deep fish species, based on the distribution of species and habitats, human activities and current spatial management.

本数据集为欧盟ATLAS项目北大西洋区域优先级评估场景所用的规划单元图层，覆盖范围为北纬18°至76°、东经36°至西经98°。该栅格图层基于25km×25km分辨率的网格构建，用于提取优先级评估所需的全部空间数据。共计31518个规划单元（带有数值的栅格单元格）对应水深不超过3500m的海域，即便局部区域可能存在更深的水深。针对连通性评估场景，仅选取与现有连通性数据范围匹配的规划单元。其中一个图层将规划单元划分为13个专为优先级评估设立的地理分区，数值范围为1至13。本数据集旨在支撑北大西洋全海域空间保护规划工作，目标覆盖北大西洋深海区域。本方法的核心目标是基于物种与栖息地分布、人类活动以及现行空间管理措施，识别脆弱海洋生态系统（Vulnerable Marine Ecosystems）和深海鱼类物种的保护优先区域。
