Near-Surface Turbulent Kinetic Energy Dissipation Rates at the Martha's Vineyard Coastal Observatory

Subsurface observations of turbulent kinetic energy (TKE) dissipation rates were collected during the 2019–2020 Air–Sea Interaction Tower (ASIT) TKE field campaign, conducted at the Air–Sea Interaction Tower over a three-month period (October 2019–January 2020). Measurements were obtained from a vertical line of bottom-mounted ADCPs and a surface-following spar buoy. Atmospheric observations from the tower are available at https://doi.org/10.5281/zenodo.12802958. Additional subsurface measurements are available at https://doi.org/10.5281/zenodo.12824154 and are also provided here (ASIT_TKE_Data_Rev2.mat and accompanying README file). The file spar_near_surface_epsilon.mat contains the following variables: Time: UTC timestamp, eps_zb_Hm: near-surface constant TKE dissipation rate, expressed as ε(z_b)·H_m, Ein: wind-to-wave energy input estimated from wave spectra (W m⁻²) spar_epsilon_data_2026.mat, Time: UTC timestamp, eps_spar: observations from spar (TKE diss rate m^2 s^-3), z_Hs: Dimensionelss depth
