Marine Invasive Species Risk Assessment for the Bering Sea

This project's objective is to provide managers and communities with information regarding invasive species known from, or potentially threatening the Bering Sea. To do this, we: a) produced a quantitative invasiveness ranking system and score for those species most likely to arrive and impact commercial fishing and subsistence, practices vital to the region’s communities, b) assessed shipping traffic to identify high risk ports of potential invasive species introduction, and c) developed species-specific habitat suitability maps for the Bering Sea, to identify regions of suitable habitat for survival and/or reproduction, for current (2003 - 2012) and future (2030 - 2039) time periods. There are 3 work products from this project that are being archived: 1. The shipping traffic figures created from publicly-available ballast water data. Specifically, included here is this file: 1523_R_Code_For_Vessel_Traffic_BallastWater.R 2. The shipping traffic figures created from confidential VMS data. Specifically, included here is this file: 1523_R_Code_For_Vessel_Traffic_VMS.R 3. Habitat Suitability Models: this dataset includes R scripts and a csv file. Specifically, included here are these files: README.md AverageConditions_byStudyPeriod.r BeringSea_Raster.r Description of Rfiles.txt Extract_Species_Rasters.r Overall_Week_Survival_byModel.r Overall_Year_Survival_byModel.r Overall_Year_Survival_byModel02.r read_netCDF_to_raster.r ReproWeeks_Summary.r Species_Tolerances.csv TaxaSuitability.r WhichOfSurvival_.r WhichOfSurvival_Summary.r WhichOfSurvival_Ensemble_WeeklyTemp.r This dataset was generated as part of NPRB project 1523.本项目旨在为管理者与沿岸社区提供已知或潜在威胁白令海（Bering Sea）的入侵物种相关资讯。为达成该目标，我们开展了以下三项工作：a）针对最有可能传入并影响该区域社区赖以存续的商业捕捞与传统生计捕捞活动的物种，构建了量化入侵性分级体系与评分标准；b）评估船舶交通流量，以识别具备高入侵物种引入风险的潜在港口；c）针对白令海生成物种专属栖息地适宜性图谱，用于识别当前（2003-2012年）与未来（2030-2039年）时段内，物种适宜生存和/或繁殖的区域。 本项目共产出三类可归档的工作成果： 1. 基于公开压载水数据生成的船舶交通流量统计数据集，对应归档文件为：1523_R_Code_For_Vessel_Traffic_BallastWater.R 2. 基于保密船舶监控系统（Vessel Monitoring System, VMS）数据生成的船舶交通流量统计数据集，对应归档文件为：1523_R_Code_For_Vessel_Traffic_VMS.R 3. 栖息地适宜性模型数据集：本数据集包含R脚本与逗号分隔值（Comma-Separated Values, CSV）文件，具体归档文件如下： README.md、AverageConditions_byStudyPeriod.r、BeringSea_Raster.r、Description of Rfiles.txt、Extract_Species_Rasters.r、Overall_Week_Survival_byModel.r、Overall_Year_Survival_byModel.r、Overall_Year_Survival_byModel02.r、read_netCDF_to_raster.r、ReproWeeks_Summary.r、Species_Tolerances.csv、TaxaSuitability.r、WhichOfSurvival_.r、WhichOfSurvival_Summary.r、WhichOfSurvival_Ensemble_WeeklyTemp.r 本数据集为北太平洋研究委员会（North Pacific Research Board, NPRB）项目1523的产出成果。
