High-resolution spatial analyses using glider data (and other high-res measurement campaigns)
This study was designed to complement the spatial analyses I conducted as part of the ODaT project (see details here) and later as part of MASSMO. Several new data products were computed from historical data, but it was recognised that the occupation of a region by a glider would increase the data density by several orders of magnitude, thus providing new information on oceanographic features.
I initially wrote a series of scripts to accept glider data and calculate measures of stratification and water properties which could then be compared to regional climatology.
I’ve continued to develop these data products, with further iterations incorporating the ability to assess the change in strength and depth of stratification in time as well as space. This means that we can infer the impact of internal wave activity on the region sampled by the gliders, for example. Below are a series of figures from the MASSMO-4 exercise in the Faroe-Shetland Channel in summer 2017.
This work was carried out in collaboration with DSTL.
