Description
Summary:<!--!introduction!--> Quantifying the heat absorbed and released by the ocean is important in understanding the role of air-sea interactions in global climate. Estimates from reanalysis products are readily available but high-resolution (both temporal and spatial) observations are much less so. To investigate ocean heat budget and air-sea interactions on a local scale, we deployed four autonomous platforms east of Barbados as part of the Eurec4a campaign, January- February 2020, in a 10 km x 10 km region. 3 Seagliders undertook 581 dives yielding 1162 vertical ocean profiles, and our 5 m wave-powered surface vessel, Caravela, travelled more than 1000 km over ground. Variations in the surface mixed layer properties are described by Seaglider profiles of temperature and salinity. For example, the mixed layer depth varies over days to weeks between 11 m and 45 m. Turbulent microstructure from one Seaglider estimates the contribution of vertical mixing to the heat budget. Variations in upper ocean heat ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
