Dataset for: Potential connectivity among spatially distinct management zones for Bonefish (Albula vulpes) via larval dispersal

The Regional Ocean Modeling System (ROMS) was used to simulate hydrodynamics in the Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico for the period 2007 to 2017. The circulation fields drove a particle tracking simulation and quantified the transport connectivity for the study area. The model domain spans the northwest Atlantic with ~7 km horizontal grid spacing and 36 vertical layers and the bathymetry was generated using 1-min gridded GEBCO (General Bathymetric Chart of the Oceans) data and smoothed using Sikirić et al. (2009) methodology to remove large gradients that may lead to numerical pressure gradient errors for the model. The model used fourth-order centered advection using k-kl mixing coefficients (corresponding to Mellor-Yamada Level 2.5) with the generic length scale vertical mixing scheme (Warner et al. 2005). The model was configured to conserve volume with a free-surface Chapman condition (Chapman 1985), a Flather condition for 2D momentum (Flather 1976), and the Orlanski-type radiation condition (Orlanski 1976) for 3D momentum and tracers (Marchesiello et al. 2001; Zeng et al. 2015a) at its only open boundary to the east. The boundary values of ocean states were derived from the daily global Hybrid Coordinate Ocean Model (HYCOM) product. The surface forcing used in the ROMS simulation was derived from the European Center for Medium-Range Weather Forecast (ECMWF) reanalysis product with 0.125-degree grid spacing every three hours. The model was initialized with daily HYCOM output and ran from January 1, 2007, to December 14, 2017. This dataset supports the publication: Zeng, X., Adams, A., Roffer, M., & He, R. (2018).

区域海洋模拟系统（Regional Ocean Modeling System，ROMS）被用于模拟2007至2017年期间大西洋、加勒比海及墨西哥湾的流体动力学过程。环流场驱动了粒子追踪模拟，并量化了研究区域的输运连通性。模型域覆盖西北大西洋，水平网格间距约7公里，包含36个垂直层；水深数据由1分网格的通用海洋水深图（General Bathymetric Chart of the Oceans，GEBCO）生成，并采用Sikirić等人（2009）的方法进行平滑处理，以消除可能导致模型数值压力梯度误差的大梯度。模型采用四阶中心平流方案，使用k-kl混合系数（对应Mellor-Yamada 2.5级），并结合通用长度尺度垂直混合方案（Warner等人，2005）。模型在其唯一的东侧开边界处配置了体积守恒的自由表面Chapman条件（Chapman 1985）、二维动量的Flather条件（Flather 1976），以及三维动量和示踪剂的Orlanski型辐射条件（Orlanski 1976；Marchesiello等人，2001；Zeng等人，2015a）。海洋状态的边界值来源于每日全球混合坐标海洋模型（Hybrid Coordinate Ocean Model，HYCOM）产品。ROMS模拟所用的表面强迫场来源于欧洲中期天气预报中心（European Center for Medium-Range Weather Forecast，ECMWF）的再分析产品，其网格间距为0.125度，时间分辨率为每3小时一次。模型以每日HYCOM输出初始化，运行时间为2007年1月1日至2017年12月14日。本数据集为以下出版物提供支持：Zeng, X., Adams, A., Roffer, M., & He, R.
