Welcome to the LOPS laboratory (Ifremer, University of Brest, CNRS, and IRD) Mixed Layer Depth Climatology website.

This website aims at giving access to some datasets of advanced oceanic variables at different levels of computation (L2 for pointwise data and L3 for gridded maps data). The datasets are mainly intended for oceanographic and climate research purposes.

Those advanced variables (e.g. Mixed Layer Depth, Barrier Layer Thickness...) are computed from in-situ measurements of Temperature (T) and Salinity (S) profiles made at sea, and obtained from oceanographic data centers (cf links towards those basic observations data in the Data Access section). The methodology used to construct the datasets is basically the one presented in de Boyer Montégut et al. (JGR, 2004) [1] with possible adjustments and evolutions.

Since November 2022, the new updated datasets will actually be hosted at SEANOE (a french publisher of marine sciences data) that enables to have a proper doi for each dataset. This website will gather all those related datasets and will give the associated link to the SEANOE page for each one of them (plus direct link for not yet updated ones).

A general presentation of the computation methodology and data description is given in the Data Description section. More details about each dataset can also be found in each webpage of the Data Access section.
