Aimed at understanding the mesoscale eddy’s effect on the subduction and dissipation of the North Pacific Subtropical Mode Water, a field experiment namely the Pacific Mode Water Ventilation Experiment (P-MoVE) was carried out in the northwestern Pacific Ocean ((Xu et al., 2016)-[https://doi.org/10.1038/ncomms10505]). During 27 March to 5 April 2014, we conducted 54 station surveys in an anticyclonic eddy (AE) and a nearby weak cyclonic eddy (CE) with a spacing of 0.25° (Figure 1). The conductivity-temperature-depth system (CTD 911plus, Sea-Bird Electronics) and microstructure probe (MSS-90, Sea & Sun Technology) were deployed to obtain temperature-salinity profiles and microscale velocity shear at these stations.

The air-sea flux and surfacw wave were observd in a fixed platform( 21º26.5' N, 111º23.5' E),  during the measurements from 6 February to 8 May 2012, the turbulence observed by the high-frequency ultrasonic anemometer (Gill R3-50) mounted at a height of 8 m, and waves were observed by the An acoustic wave and current (AWAC) sensor (Nortek, Rud, Norway).   The data provided are: Time:  YYYYMMDDHHNN; U8: Wind speed observed from ultrasonic anemometer fixed at 8 m height above the sea surface; Wind direction(from): Wind direction observed from ultrasonic anemometer; Wave direction(from): wave direction from acoustic wave and current (AWAC) sensor; Atmospheric Stability (z/L): Atmospheric Stability z/L, where z is height, and L is Obukhov length; wave age (cp/U8): Peak wave age ; τx/ρ: total wind stress  in longitudinal direction ; τy/ρ: total wind stress in lateral direction; τtx/ρ: turblent wind stress  in longitudinal direction ; τty/ρ: turblent wind stress in lateral direction; Cd(COARE): the drag coefficient computed by COARE 3.0 ; case: It represent the cases shown in figures 6~7 in the main text.Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.
