Modeled Lagrangian data 1km horizontal resolution ROMS run to investigate the influence of mesoscale and submesoscale circulations on the trajectories of sinking particles, Gulf of Mexico, April 20-30, 2012 (spring case) October 2-12, 2012 (fall case)

Modeled Lagrangian data using a 1km horizontal resolution Regional Ocean Modeling System (ROMS) run. The Lagrangian model adopted is LTRANS v2b. Particles with sinking speeds of 20 m d-1, 30 m d-1, 50 m d-1 and 100 m d-1 are released at two sediment traps, GC600 (27.375 N, -90.511667 W) and AT357 (27.525 N, -89.71 W) in April and October 2012. Backward simulation of particles is applied to investigate the influence of mesoscale and submesoscale circulations on the trajectories of sinking particles in the Gulf of Mexico.本数据集采用水平分辨率为1千米的区域海洋建模系统（Regional Ocean Modeling System, ROMS）模拟生成拉格朗日（Lagrangian）数据。本次模拟采用的拉格朗日模型为LTRANS v2b。于2012年4月与10月，分别在两个沉积物捕获器GC600（北纬27.375°，西经90.511667°）与AT357（北纬27.525°，西经89.71°）处，释放沉降速率分别为20 m·d⁻¹、30 m·d⁻¹、50 m·d⁻¹及100 m·d⁻¹的粒子。通过对粒子开展反向模拟，旨在探究墨西哥湾内中尺度与亚中尺度环流对沉降粒子运动轨迹的影响。
