Long-term observations of the marine environment are imperative to enable us to see how the marine environment is changing and to provide a baseline for projections of how it may change into the future. PML has a long standing network of in situ
observations, from the Western Channel Observatory
in the western English Channel to the Atlantic Meridional Transect
sampling the length of the Atlantic Ocean each year. However, it is not possible to sample the entire global ocean and PML is at the forefront of utilising remote sensing platforms including satellite and aircraft observations to conduct research on the physical and ecological processes in oceanic, coastal and inland waters.
