The directory contains mesoscale eddy trajectory data and eddy colocation data with Argo floats from TOEddies Dynamical Atlas (Laxenaire et al., 2018) for the Atlantic Ocean. Data are used in the manuscript “Characterizing mesoscale eddies of eastern upwelling origins in the Atlantic Ocean and their role in offshore transport” submitted to Frontiers in Marine Science. Data are intended for the reviewers and may be updated until the review process is complete. All data are stored in mat format. 1) Trajectory data contains two main variables -Anticyclonic Trajectories - Cyclonic Trajectories each row is a different eddy trajectory. For each eddy trajectory, relevant information is stored in each column as described in Fields_Trajectories 2) Argo colocalisation data (seperately for north and south AT) contains one main variable Argo_proxy each row is a different Argo profile for which relevant information can be accessed in each column. Each column stores relevant information as described in Fields_Argo_proxy. The eddy polarity (Field 19) is defined as -1| 1 for cyclone | anticyclone Selected cyclonic eddies presented in section 3.3 of our paper have ID Trajectory numbers 871389 and 75 9884 for Cyclone C0 and Cyclone C1 respectively. Argo floats remained trapped in the cyclones can be access from the Argo_proxy (WMO 1901310 for cyclone C0 and WMO 1900744, 1901567 6900728, 6900931 for cyclone C1).
