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.
